Organic Compounds ’ VOCs),而多數的VOCs對人體有一定毒性,必 須加以處理;其中,焚化法為VOCs廢氣處理方式之一種, 在適當條件下之VOCs去除率可達99%以上,燃燒後之產物 通常為水、二氧化碳、氮氧化物、硫氧化物…等,故為一 種可有效處理廢氣中所含之VOCs及臭氣之方法。 次按,VOCs通常會採用蓄熱焚化爐(Regenerative Thermal Oxidizer,RT0)予以焚化,第一圖所示為常見之 雙槽式蓄熱焚化爐,其於内部填充蓄熱材料(11a、lib)之 第一與第二蓄熱槽(l〇a、l〇b)之間連結燃燒室(12),並將 一焚化氣流控制裝置(20)連結至每一蓄熱槽(10a、10b), 而該焚化氣流控制裝置(20)之控制器(21)根據所設定之切 換時間控制切斷閥群(22a、22b、22c、22d)之啟閉,進而 切換焚化氣流於該第一與第二蓄熱槽(1 〇a、10b)之流向(一 流入且一流出);藉此,其操作包含兩步驟:步驟1 :令切 201217710 斷間(22a)開、切斷閥(22b)關、切斷閥(22c)關、切斷閥(22d) 開’而將待焚化廢氣藉由該焚化氣流控制裝置(2〇)導入第 一蓄熱槽(l〇a)預熱至一定溫度,然後通過燃燒室(12)進入 第二蓄熱槽(l〇b) ’亦即燃燒後氣流之高溫會轉移儲存於第 二蓄熱槽(10b)中;步驟2 :待經過所設定之切換時間後, 該焚化氣流控制裝置(2〇)則令切斷閥(22a)關、切斷閥(22b) 開、切斷閥(22c)開、切斷閥(22d)關,而改將待焚化廢氣 導入已蓄熱之第二蓄熱槽(10b)將待焚化廢氣體預熱,再通 過燃燒室(12)進入已冷卻之第一蓄熱槽(1〇a),燃燒後氣流 之高溫則再轉移儲存於第一蓄熱槽(1〇a)中,而完成一循環 熱交換。

Description of the Invention: [Technical Field] The present invention relates to a self-cleaning device and method for a heat storage incinerator, and more particularly to extending a flow switching cycle of an incineration gas stream, and letting the temperature at the outlet end of the heat storage tank reach the set The designer who switches the temperature from the net incineration and uses the high temperature to thermally desorb or decompose the attached material at the bottom of the heat storage material to restore its heat storage function. [Prior Art] Organic solvents, widely used in life and production, are easily volatilized into gases at room temperature, so they are also known as Volatile Organic Compounds 'VOCs. Most VOCs are toxic to humans. The incineration method is one of the treatment methods of VOCs waste gas. Under suitable conditions, the removal rate of VOCs can reach more than 99%, and the products after combustion are usually water, carbon dioxide, nitrogen oxides, sulfur oxides, etc. It is a method for effectively treating VOCs and odors contained in exhaust gas. Sub-press, VOCs are usually incinerated using a Regenerative Thermal Oxidizer (RT0). The first figure shows a common two-slot regenerative incinerator, which is filled with the first heat storage material (11a, lib). A combustion chamber (12) is coupled between the second heat storage tanks (10a, lb), and an incineration gas flow control device (20) is coupled to each of the heat storage tanks (10a, 10b), and the incineration gas flow control device (20) The controller (21) controls the opening and closing of the shut-off valve group (22a, 22b, 22c, 22d) according to the set switching time, and further switches the incineration gas flow to the first and second heat storage tanks (1 〇a) , 10b) flow direction (one inflow and first-class out); thereby, its operation consists of two steps: Step 1: make cut 201217710 break (22a) open, shut off valve (22b) off, shut off valve (22c) off The shut-off valve (22d) is opened, and the incineration gas to be incinerated is introduced into the first heat storage tank (l〇a) by the incineration gas flow control device (2〇) to be preheated to a certain temperature, and then enters the first stage through the combustion chamber (12). The second heat storage tank (l〇b) 'that is, the high temperature of the gas stream after combustion will be transferred and stored in the second heat storage tank (10b) Step 2: After the set switching time, the incineration airflow control device (2〇) closes the shut-off valve (22a), shuts off the valve (22b), and closes the shut-off valve (22c). The shut-off valve (22d) is closed, and the waste gas to be incinerated is introduced into the second heat storage tank (10b) that has been recharged to preheat the waste gas to be incinerated, and then enters the cooled first heat storage tank through the combustion chamber (12) (1〇 a) The high temperature of the gas stream after combustion is transferred to the first heat storage tank (1〇a) to complete a cycle of heat exchange. However, the temperature of the heat storage material (lla, lib) will gradually decrease with depth. After using the incinerator for a period of time, the bottom of the heat storage material (11&, lib) will have high boiling organic matter and organic Polymerized monomer, oil mist and tar-like substances, even causing clogging, causing the heat storage material (11a, lib) to gradually lose heat storage function; wherein the aforementioned adhesion substance can be heated after the incinerator system is turned off Water or solvent is removed, but it can only be removed by shallow layer and cannot be completely removed. In addition, another method of removing the adhering substances is to introduce the first and second heat storage tanks one by one using an external heat source (l〇a The flushing airflow of 10b) is heated, and the heat accumulating material (11a, lib) is bake-out from the bottom to remove the adhering substance, but the design must add a set of external heat source and flushing gas pipeline to increase the fuel. And the cost of the equipment. In addition, when the double-tank type thermal storage incinerator is switched between preheating/heat storage in the heat storage tank, the gas to be incinerated in the preheating heat storage tank will be discharged because it has not been incinerated, so there will be a problem of periodic discharge of unburned gas in 201217710. In order to solve the above problems of the two-tank type heat storage incinerator, there is also a three (multi) trough type regenerative incinerator as shown in the second figure, which is internally filled with the first and second heat storage materials (3ia, 31b, 31c). A combustion chamber (32) is coupled to the third heat storage tank (30a, 30b, 30c), and an incineration gas flow control device (4〇) is coupled to each of the heat storage tanks (3〇a, 30b, 30c), and each A heat storage tank (3〇a, 3〇b, 30c) is connected to a flushing " airflow control device (50) 'the controller (41) of the incineration airflow control device (40), according to the set switching time control cut Opening and closing of the shut-off valve group (42a, 42b, 42c, 42d, 42e, 42f, 51a, 51b, 51c), thereby switching the flow of the incineration gas stream and the flushing gas flow in each of the heat storage tanks (30a, 30b, 30c) ( An incineration gas stream flows in, an incineration gas stream flows out and a flushing gas stream flows in; thereby, a heat storage tank is added to the double-tank type heat storage incinerator, and a step of flushing air flow is introduced between the heat storage and preheating steps (detailed The operation steps are not the patent subject of this case, and will not be described again) No problem will incineration incinerator exhaust gases of the periodic, but still by an external heat source to heat the purge stream, to serve the storage material (31a, 31b, 31c) from the bottom upwards hot baking clear adhering substance. SUMMARY OF THE INVENTION The main object of the present invention is to provide a self-cleaning device and method for a heat storage incinerator, which has the effect of completely removing the material adhering to the heat storage material without an external heat source.

The controller automatically switches between the normal mode and the self-cleaning mode according to the pressure difference between the inlet end and the outlet end of the set heat storage tank. Alternatively, the controller manually switches between the normal mode and the self-clean mode. Furthermore, the self-cleaning mode controls the opening and closing of the shut-off valve group according to the set self-cleaning incineration switching time, thereby forcibly switching the flow direction of the incineration gas flow in each heat storage tank, thereby serving as a safety mechanism for preventing high temperature smoldering of the heat storage tank. . In addition, the enthalpy is a double tank or a multi tank. Further, the normal incineration switching time is 60 to 18 sec., and the self-incineration switching temperature is 2 〇〇 to 45 〇.匚, the self-incineration switching time is 2 to 6 times of the normal incineration switching time. In addition, the self-cleaning method of the regenerative incinerator of the present invention provides a self-cleaning mode switching signal, and the inflowing mode of the incineration gas flow in each of the regenerators is controlled by the normal mode of the flow switching according to the normal incineration switching time. Self-cleaning incineration switching temperature control flow switching mode of self-cleaning mode 0 201217710 ' The self-cleaning mode conversion signal is the pressure difference between the inlet end and the outlet end of the regenerator and the input of the personnel. In addition, the self-cleaning mode is forced to (4) the inflow of the incineration gas flow in each of the heat storage tanks according to the set self-cleaning incineration switching time as a safety mechanism for preventing high-temperature and wide-burning of the heat storage tank. In addition, the normal incineration switching time is 6 〇 to (10) seconds, and the self-cleaning switching temperature is a touch of ~450 ° C, and the self-cleaning switching time is 2 J to 6 times of the normal incineration switching time. [Embodiment] φ First, as shown in the third figure, the self-cleaning device of the present invention is a two-tank f-heat incinerator, which is filled with a heat storage material (lla, Ll)) connecting the combustion chamber (12) between the first and second heat storage tanks (10a, l), and connecting an incineration gas flow control device (20) to each of the heat storage tanks (1〇a, 1) 〇b), and a thermometer (6〇) is disposed at the outlet end of the incineration gas stream of the incineration gas flow control device (20), and the temperature is sixty (60) connected to the controller of the incineration gas flow control device (2〇) (21 And the controller (21) enables the incineration airflow to perform mode switching and flow direction switching in the normal mode or the self-cleaning mode.

The flow direction of the grooves (10a, 1〇b), and the self-cleaning mode controls the opening and closing of the shut-off valve group (22a, 22b, 22c, 22d) according to the set self-cleaning switching temperature, and then switches the incineration gas flow to each a flow direction of a heat storage tank (l〇a, 10b); wherein the normal mode is an operation mode of a general regenerative incinerator, and the self-cleaning mode is an operation mode of the invention added in 201217710, which is an incineration airflow The flow switching cycle is extended from the normal mode, so that the temperature at the outlet end of the heat storage tank (10a, 10b) reaches the self-cleaning switching temperature (this case is set to 200 to 45 (rc), and the heat storage material (lla, llb) is taken by high temperature. The bottom attached material is decomposed and removed to restore the heat storage function of the heat storage material (11a, lib). Further, a first pressure gauge (71) is further disposed at the inlet end of the incineration gas stream of the incineration gas flow control device (20) and is disposed at the outlet. end a second pressure gauge (72) is coupled to the controller (21) of the incineration airflow control device (20), and the controller (21) is The set pressure difference of the heat storage tank automatically switches between the normal mode and the self-cleaning mode; therefore, when the pressure difference between the inlet end and the outlet end of the heat storage tank increases sharply, the heat storage material (lla, llb) is attached. The substance forms a blockage. 'The controller (21) converts the operation mode of the incinerator from the normal mode to the self-clean mode; and when the inlet end and the outlet end of the heat storage tank return to the normal pressure difference, it indicates the heat storage material (lla) The attached material of Ub) has been decomposed and removed. The controller (21) converts the operation mode of the incinerator from the self-cleaning φ mode back to the normal mode; however, the controller (21) is not only according to the heat storage tank pressure set. The difference automatically switches between the normal mode and the self-clean mode, and can also be manually switched between the normal mode and the self-clean mode by the person. In addition, in order to prevent the thermometer (60) from being dangerous, the self-cleaning mode In addition, according to the set self-cleaning incineration switching time (this case is set to 2 to 6 times of the normal incineration switching time), the shut-off valve group (22a, 22b, 22c, 22d) is controlled to open and close, and then the incineration gas flow is forcibly switched.

The incineration gas flow switching cycle is about 270 seconds. In addition, the operating conditions of the third application example of the present invention in the double-tank type thermal storage incinerator are as follows: The waste gas to be incinerated contains high boiling point dimethyl decylamine (DMF, boiling point 153 ° C); the inlet temperature of the normal mode is 5 (TC, The incineration temperature is 850 °C, the average outlet temperature is 90 °C, the incineration gas flow switching period is 90 seconds; the inlet temperature of the self-cleaning mode is 50 °C, the incineration temperature is 850 °C, the outlet temperature is 200 °C, then the incineration gas flow direction is switched, and the incineration gas flow is switched. The cycle is about 210 seconds. In addition, as shown in the fourth figure, the second embodiment of the self-cleaning 201217710 device of the regenerative incinerator of the present invention is a multi-tank regenerative incinerator, which is internally filled with a heat storage material (31a). a combustion chamber (32) connected between the first, second and third heat storage tanks (31a, 30b, 30c) of 31, 31c), and an incineration gas flow control device (40) coupled to each heat storage tank (30a) And 30b, 30c), and each of the heat storage tanks (30a, 30b, 30c) is connected to a flushing airflow control device (50), and a thermometer is arranged at the outlet end of the incineration airflow of the incineration airflow control device (40). 60), the thermometer (60) is linked to the incineration The airflow control device (40) is a controller (41), and the controller (41) causes the incineration airflow to perform a mode switching and a flow direction switching in a normal mode or a self-cleaning mode. However, the normal mode is based on the set normal state. The incineration switching time (usually 60 to 180 seconds) controls the opening and closing of the shut-off valve group (42a, 42b, 42c, 42d, 42e, 42f, 51a, 51b, 51c), thereby switching the incineration gas flow and the flushing gas flow to each heat storage. The flow direction of the grooves (30a, 30b, 30c); further, the self-cleaning mode controls the shut-off valve group (42a, 42b, 42c, 42d, 42e, 42f, 51a, 51b, 51c) according to the set self-cleaning switching temperature Opening and closing, and then switching the flow direction of the incineration gas stream and the flushing gas flow in each of the heat storage tanks (10a, 1 Ob); the operation steps are the same as those in the first embodiment, and will not be described again. 9 Thereby, the present invention is multi-tank type heat storage.
