Abstract
Disclosed are a blowing method and a device thereof for a pulsed jet cloth filter. The blowing method is characterized in that an upper box of the cloth filter is divided into at least two small gas purification chambers which are mutually independent, each small gas purification chamber is communicated by a gas purification discharging pipe and a gas purification collecting pipe, and during ash removal, nozzles of blowing pipes blow reverseblown gas into corresponding small gas purification chambers through the gas purification discharging pipes. The device comprises the upper box, a middle box and a lower box, wherein the middle box is a cloth bag chamber and the upper box is divided into a plurality of small gas purification chambers which are mutually independent. The device is characterized in that the gas purification discharging pipes are arranged outside the small gas purification chambers, a plurality of gas purification discharging pipes are communicated with the gas purification collecting pipes, and gas purification discharging pipes corresponding to the small gas purification chambers are provided with the nozzles of the blowing pipes. The device is simple in structure, small in size, low in material consumption and cost, and convenient to install and maintain. Practices prove that same performances can be achieved through the adoption of the blowing method and the device thereof, raw materials can be saved by about 10%, and economic benefits are obvious.
Description
Technical field:
The device that the present invention relates to a kind of pulsed jet cloth filter blowing process and implement this method is a pulse bag cell deduster.
Background technology:
Sack cleaner, especially pulsed jet cloth filter are to use the widest dust collection method.At present, the blowing method of sack cleaner all adopted the pipeline injection method during reality was produced, and promptly the winding-up pipe directs at cloth bag." the blast furnace gas drying bag dust removing device bi-directional electromagnetic pulse jetting deashing device " of CN200620167649.3 bulletin for example, this device is exactly at several nozzles of winding-up Guan Shangshe, and wherein cloth bag of each nozzle correspondence is directly blown to cloth bag.For another example, " the plug-in type reverse gas cleaning devices and methods therefor that is used for sack cleaner " of CN200510058804.8 bulletin, the winding-up pipe of this device is deep among the cloth bag.And for example, " combined filter tube element pulse dust-collector " of CN200610046580.3 bulletin, the connecting place of this deduster pure qi (oxygen) case and outlet is provided with the induction tunnel that the blowback dedusting is used.Also have CN200920217238.4 bulletin " a kind of pulsed jet cloth filter ", this deduster bottom in cell is provided with ductor.As above several examples have a common defective, and promptly they all are provided with device between purge gas spout and air-purifying chamber outlet, or are the winding-up pipes of lengthening, or are induction tunnel, or are ductor.Resemble this blowing method and device thereof, discuss dust removing effects for the present, single with regard to device structure, it is problem the most significantly, is that the volume that causes whole device strengthens, consumptive material is many, cost is high.Therefore be necessary to improve.
Summary of the invention:
Task of the present invention is to the problems referred to above, a kind of pulsed jet cloth filter blowing process is provided, and device to be a pulse bag cell deduster.This pulsed jet cloth filter blowing process and device thereof not only can guarantee and optimize dust removing effects, and can make that apparatus structure is simple, volume is little, are adapted to difform deduster; Reach same usefulness; Can save material, reduce equipment cost, and be convenient to I&M.
One of its technical solution is: a kind of pulsed jet cloth filter blowing process; Use existing gases at high pressure blowing device; With gases at high pressure is power; Exert pressure to the cloth bag blowback of sack cleaner through the winding-up pipe; It is characterized in that: the upper box of sack cleaner is separated into is no less than 2 separate cell air-purifying chambers, each cell air-purifying chamber is communicated with by pure qi (oxygen) delivery line and pure qi (oxygen) manifold trunk, and winding-up pipe spout is blown into corresponding cell air-purifying chamber with purge gas through the pure qi (oxygen) delivery line during deashing.
Two of its technical solution is: a kind of device of implementing aforementioned pulsed jet cloth filter blowing process; Be pulse bag cell deduster, be divided into three casings in upper, middle and lower, wherein middle casing is the cloth bag chamber; Upper box is divided into the cell air-purifying chamber of several independent; It is characterized in that: cell air-purifying chamber peripheral hardware pure qi (oxygen) delivery line, several pure qi (oxygen) delivery lines are communicated in the pure qi (oxygen) manifold trunk, and the spout of winding-up pipe is set corresponding to the pure qi (oxygen) delivery line of cell air-purifying chamber.
Compared with prior art; Advantage of the present invention is: owing between the winding-up pipe spout of pulsed jet cloth filter and cell air-purifying chamber, the pure qi (oxygen) delivery line only is set; And do not resemble the device of one type of winding-up pipe of the prior art, induction tunnel, pure qi (oxygen) block valve etc.; Therefore whole apparatus structure is simple, volume is little, consumptive material is few, and equipment cost is low, and is convenient to I&M.Facts have proved, adopt present technique can save material about 10%, have tangible economic benefit.And; Because the cell air-purifying chamber is established the pure qi (oxygen) delivery line and is communicated with the pure qi (oxygen) manifold trunk; And winding-up pipe spout is extend in the pure qi (oxygen) manifold trunk jet corresponding to the cell air-purifying chamber through the pure qi (oxygen) delivery line, therefore, not only can adapt to difform dedusters such as resembling circle, rectangle.And the entering effect of its gas compared to prior art by nozzle directly to cloth bag carry out blowback come gentlely, even; No delivery line guiding compared to prior art and lean on ductor with purge gas import carry out blowback come concentratedly, strong, so can optimize the winding-up effect.
Description of drawings:
Fig. 1 is the structural representation of pulse bag cell deduster of the present invention.
Fig. 2 is that the A-A of Fig. 1 cuts open left view.
Fig. 3 is that the B-B of Fig. 1 cuts open amplification plan view.
The specific embodiment:
Embodiment 1; A kind of pulsed jet cloth filter blowing process is used existing gases at high pressure blowing device, is power with gases at high pressure; Exert pressure to the cloth bag blowback through the winding-up pipe; It is characterized in that: upper box is separated into and is no less than 2 separate cell air-purifying chambers, and the cell air-purifying chamber is communicated with by pure qi (oxygen) delivery line and pure qi (oxygen) manifold trunk, and winding-up pipe spout is blown into corresponding cell air-purifying chamber with purge gas through the pure qi (oxygen) delivery line during deashing.
Like Fig. 1-shown in Figure 3; Pulse bag cell deduster provided by the invention is divided into three casings in upper, middle and lower, and wherein middle casing 1 is the cloth bag chamber; Upper box is divided into the cell air-purifying chamber of several independent, and corresponding below the cell air-purifying chamber 2 is several rows of cloth bag.It is characterized in that: cell air-purifying chamber 2 peripheral hardware pure qi (oxygen) delivery lines 3, several pure qi (oxygen) delivery lines 3 are communicated in pure qi (oxygen) manifold trunk 4, and promptly cell air-purifying chamber 2 is communicated with through pure qi (oxygen) delivery line 3 and pure qi (oxygen) manifold trunk 4.The spout 6 of winding-up pipe 5 is set corresponding to the pure qi (oxygen) delivery line 3 of cell air-purifying chamber 2.Be the spout 6 of each winding-up pipe 5 all corresponding the pure qi (oxygen) delivery line 3 of cell air-purifying chamber 2.That is to say that when device work, the gases at high pressure blowing device is blown into corresponding cell air-purifying chamber through the pure qi (oxygen) delivery line with purge gas, thereby accomplishes the deashing task.
