Description

Technical Field

[0001] The present application relates to the technical field of industrial waste gas dust removal, and specifically to an industrial waste gas dust removal device. Background Art

[0002] Industrial waste gas contains a large amount of dust. If dust and particulate matter are discharged directly into the atmosphere without treatment, it will cause serious pollution to the environment, affect air quality, and endanger human health. Therefore, dust removal is an important means to reduce pollution and protect the environment.

[0003] Application No. 202220444943.3 discloses an industrial waste gas dust removal device, including an equipment body, an installation groove, a sealing gasket, a filter screen and a spray device, etc. After the filter screen on the fixed mesh plate has been used for filtering for a long time, the fixing bolts on the disassembly can be rotated and toggled through the external thread to be removed from the installation screw groove on the equipment body, and the disassembly cover itself can be directly pulled out and removed from the inside of the installation groove, so that the multiple groups of filter screens installed inside the disassembly cover can be taken out of the equipment body together for separate subsequent maintenance and cleaning. After cleaning, the threaded fixed installation is similarly used again, thereby facilitating the removal and cleaning of the filter screen inside the disassembly cover and improving the filtering effect of the waste gas dust removal.

[0004] However, in use, there are the following defects:

[0005] Although a detachable filter is used for easy cleaning, the device cannot remove dust temporarily when it is taken out for cleaning, and needs to wait until the filter is reinstalled before it can continue to work, which affects the dust removal efficiency of the device. Utility Model Content

[0006] The purpose of the present application is to provide an industrial waste gas dust removal device, which solves the problem in the background art that although a detachable filter is used for easy cleaning, the device cannot perform dust removal when it is taken out for cleaning, and needs to wait until the filter is reinstalled before it can continue to work, which affects the dust removal efficiency of the device.

[0007] To achieve the above-mentioned objectives, the present application provides the following technical solutions: an industrial waste gas dust removal device, comprising a box body, an exhaust fan, a support block and a water collecting tank, an air inlet is provided at the top of the box body, an air outlet is provided at the lower right side wall of the box body, a water pipe passes through the upper inner wall of the box body, and two upper parallel slide grooves are provided on the left and right inner walls of the box body below the water pipe, and the inner sides of the slide grooves are horizontally slidably connected with slide bars, and the slide bars are respectively fixedly connected to the left and right side walls of the upper filter frame and the lower filter frame, and the two side walls of the box body parallel to the water pipes are respectively provided with upper strip grooves and lower strip grooves, the upper filter frame is horizontally slidably connected to the box body through the upper strip grooves, and the lower filter frame is horizontally slidably connected to the box body through the lower strip grooves.

[0008] In this technical solution, exhaust gas is discharged into the box through the air inlet, and then the water pipe is connected to a water source to spray water mist into the box through a branch nozzle. The water droplets will be better collected after contacting the dust in the exhaust gas, and the dust can be continuously collected through the upper filter frame, the lower filter frame and the filter. The dust will move downward under the spraying of water droplets, and then be intercepted by the filter on the upper filter frame or the lower filter frame, and the collected dust can be cleaned without delaying the dust removal work through the slide groove, the slide bar, the upper strip groove and the lower strip groove. The exhaust gas discharge is temporarily closed, and then the handle is held to pull the upper filter frame or the lower filter frame out of the upper strip groove and the lower strip groove respectively, and then the filter is replaced. When cleaning the filter on one of the filter frames, the other filter can continue to perform dust removal work, so as not to delay the operation of the device and improve the dust removal efficiency. The water mist and exhaust gas can be blown downward by the exhaust fan. The heat in the exhaust gas will produce a large amount of water vapor floating in the box after contacting the water mist. At this time, the exhaust gas needs to be guided downward. After the exhaust fan is started with an external power supply, the exhaust fan will blow air toward the bottom of the box, thereby driving the water vapor and exhaust gas to move downward together. During the movement, the dust will be intercepted by the filter, thereby improving the dust removal efficiency. The exhaust gas after dust removal will leave from the air outlet, and the water droplets in the box will fall into the sump below.

[0009] As an optional solution of the technical solution of the present application, the inner side walls of the upper filter frame and the lower filter frame are fixedly connected with a support block, and the inner sides of the upper filter frame and the lower filter frame above the support block are detachably mounted with a filter screen.

[0010] As an optional solution of the technical solution of the present application, exhaust fans are fixedly installed on the top of the box body on both sides of the air inlet.

[0011] As an optional solution of the technical solution of the present application, a plurality of branch nozzles are evenly arranged on the side wall of the water pipe located on the inner side of the box body.

[0012] As an optional solution of the technical solution of the present application, the bottom of the box is connected to a water collecting tank.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. The present application uses the slide groove, the slide bar, the upper bar groove and the lower bar groove to clean the collected dust without delaying the dust removal work, temporarily shut down the exhaust gas discharge, and then hold the handle to pull the upper filter frame or the lower filter frame out of the upper bar groove and the lower bar groove respectively, and then replace and clean the filter. When cleaning the filter on one of the filter frames, the other filter can continue to perform dust removal work, thereby not delaying the operation of the device and improving the dust removal efficiency.

[0015] 2. In this application, the water mist and exhaust gas can be blown downwards by the exhaust fan. The heat in the exhaust gas will generate a large amount of water vapor floating in the box after coming into contact with the water mist. At this time, the exhaust gas needs to be guided downwards. After the exhaust fan is started with an external power supply, the exhaust fan will blow air downwards of the box, thereby driving the water vapor and exhaust gas to move downwards together. During the movement, the dust will be intercepted by the filter, thereby improving the dust removal efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
