Description

A regenerative thermal incinerator exhaust gas treatment device with heat recovery function

Technical field

The present invention relates to the technical field of incinerator exhaust gas treatment, and is specifically a regenerative thermal incinerator exhaust gas treatment device with heat recovery function.

Background technique

Regenerative thermal incinerator, also known as: regenerative oxidation furnace, heats organic waste gas to above 760 degrees Celsius to oxidize and decompose VOC in the waste gas into carbon dioxide and water, and allows the high-temperature gas generated by oxidation to flow through special ceramics The heat storage body heats up the ceramic body to "store heat". This "heat storage" is used to preheat the subsequent incoming organic waste gas, thereby saving fuel consumption for heating up the waste gas. The ceramic regenerator should be divided into two or more zones or chambers. Each regenerator undergoes the procedures of heat storage-heat release-cleaning in turn, starting over and over again, and working continuously. After the regenerator "releases heat", part of the processed clean exhaust gas should be introduced immediately to clean the regenerator (to ensure that the VOC removal rate is above 95%). Only after the cleaning is completed can the "heat storage" process be entered. , since the existing regenerative thermal incinerator needs to emit waste gas during use, and the direct discharge of non-volatile substances in the waste gas into the external environment will cause pollution, therefore, additional waste gas treatment devices need to be used.

When the existing regenerative thermal incinerator discharges waste gas through the waste gas treatment device, it can purify the non-volatile substances in the waste gas, but the heat in the waste gas cannot be recycled, which will cause a waste of energy and accelerate energy consumption.

Working principle of the invention:

When the exhaust gas enters the conduction chamber through the air inlet pipe 6, the heat in the exhaust gas can be absorbed by the heat conduction plate 4, and the exhaust gas in the conduction chamber can enter the treatment tank 1 through the gas transmission pipe 7, which facilitates the filter 2 to filter the waste gas. The magazine particles are filtered and intercepted. At the same time, the water pump 8 is started to cause the nozzle 11 to spray liquefied water, so that the liquefied water forms steam under the heating effect of the heat conductor plate 4, thereby realizing the recovery and utilization of the heat in the exhaust gas, thereby allowing the exhaust gas to be The fine impurity particles combine into large impurity particles, thereby improving the filtration and purification effect of the filter screen 2 on the exhaust gas.

When the exhaust gas in the air inlet pipe 6 is transported rapidly, due to the one-way limiting effect of the electric one-way valve 1304 on the connecting pipe 1303, an air pressure difference is formed between the air inlet pipe 6 and the connecting pipe 1303, thereby forming a pressure difference in the tank 1302 through the connecting pipe 1303. The suction effect causes the movable plate 1305 in the tank 1302 to compress the support spring 1306 and move upward. At the same time, because the transmission rod 1307 and the perforation 1308 are in sliding fit, the movable plate 1305 can be driven by the transmission rod 1307 during the movement. The moving ring 1309 moves upward synchronously, thereby providing operating driving force for the air pressure utilization assembly 14 .

In the initial state, when exhaust gas is rapidly transported in the intake pipe 6, when the movable plate 1305 drives the moving ring 1309 to move to the highest point, the closing button 1312 can be pressed by the pressing block 1310, thereby closing the electric one-way valve 1304, allowing the movable plate 1305 to It can move downward under the elastic force of the support spring 1306. When the movable plate 1305 drives the moving ring 1309 to move to the lowest point, the start button 1311 can be pressed through the pressing block 1310, thereby allowing the electric one-way valve 1304 to open, which facilitates the movable plate 1305. It can move upward under the action of air pressure and start again and again, and can realize the longitudinal reciprocating movement of the moving ring 1309 during the rapid transportation of exhaust gas.

When the moving ring 1309 moves upward, since the sliding block 1405 and the sliding channel 1404 are in sliding coordination, the moving ring 1309 can cause the rotating column 1403 to rotate clockwise through the squeezing effect of the sliding block 1405 on the sliding channel 1404, thus During the rotation process, the rotary column 1403 drives the turntable 1408 to rotate synchronously through the screw 1402, the rotating shaft 1406 and the linkage rod 1407, so that the fan blade 1409 is driven by the turntable 1408 to rotate clockwise, which can form a "blowing" and improve the exhaust gas flow rate. To handle the upwelling rate in the tank 1, when the moving ring 1309 moves down, the rotary column 1403 can rotate counterclockwise driven by the slider 1405, thereby driving the turntable 1408 through the screw 1402, the rotating shaft 1406 and the linkage rod 1407. The counterclockwise rotation causes the fan blade 1409 to form a "suction" in the treatment tank 1, which is beneficial to the diffusion of water vapor in the treatment tank 1, thereby improving the binding effect of impurity particles in the exhaust gas.

When the screw 1402 rotates clockwise, the moving block 1410 can move upward along the screw 1402 through the threaded cooperation between the screw 1402 and the screw hole 1411, so that the moving block 1410 can pass through the connecting plate 1412 and the connecting plate 1412 during the movement. The sliding rod 1413 drives the linkage ring 1415 to move upward synchronously, so that the cleaning pad 1416 on the linkage ring 1415 can wipe and clean the surface of the heat transfer plate 4, which can prevent dirt from adhering to the surface of the heat transfer plate 4 and affecting the heating effect of the heat transfer plate 4. , at the same time, when the linkage ring 1415 moves to the highest point driven by the slide rod 1413, the linkage ring 1415 impacts the filter screen 2, causing the filter screen 2 to vibrate, thereby allowing the dirt attached to the filter screen 2 to The falling of impurities can ensure the continuous use of filter 2.
