Problems solved by technology

Therefore, a waste gas treatment device with complete functions and good evolution effect is needed. Nowadays, the treatment devices are relatively single, and the purification of many waste gases usually fails to achieve the expected effect or does not meet the standard at all, which is not conducive to environmental protection.

Embodiment 1

[0031] The present invention is realized through the following technical solutions, as figure 1 As shown, a high-temperature exhaust gas filtering device is connected with the exhaust gas output pipeline, and includes a box body 1 provided with an air inlet 11 and an output port. The inside of the box body 1 includes a gas cooling chamber equipped with an exhaust gas cooling mechanism and cooling A treatment chamber where the post-gas is filtered; the waste gas cooling mechanism includes a cooling pipe 5 fixedly installed in the gas cooling chamber, and one end of the cooling pipe 5 is connected to the air inlet 11; an exhaust fan 7 is installed at the output port.

[0032] It should be noted that, through the above improvements, when in use, the air inlet 11 is connected to the exhaust gas pipeline, and the exhaust fan 7 is turned on, and the exhaust gas will enter the cooling pipeline 5 for cooling, so that the temperature of the exhaust gas is lowered, and the filtration pro...

Embodiment 2

[0035] This embodiment is further optimized on the basis of the above embodiments, such as figure 1 As shown, the cooling pipeline 5 is spiral; the end of the cooling pipeline 5 close to the air inlet 11 is provided with a filter 51 , and the end of the cooling pipeline 5 away from the air inlet 11 communicates with the box body 1 .

[0036] An active carbon filter layer 4 , a PM2.5 filter screen 3 , and an open-cell foamed aluminum filter layer are slidingly installed in the treatment chamber in sequence along the vertical direction.

[0037] The open-cell foam aluminum filter layer includes an open-cell foam aluminum plate 2 and a stainless steel filter screen 21 for supporting the open-cell foam aluminum plate 2 , and the stainless steel filter screen 21 is slidably installed in the box body 1 .

[0038] The porosity of the open-cell aluminum foam filter body is 60%-90%.

[0039] A dust storage tank 6 is also slidably installed inside the bottom of the box body 1 . The du...

Embodiment 3

[0044] This embodiment is the best embodiment of the present invention, as figure 1 As shown, a high-temperature exhaust gas filtering device is connected with the exhaust gas output pipeline, and includes a box body 1 provided with an air inlet 11 and an output port. The inside of the box body 1 includes a gas cooling chamber equipped with an exhaust gas cooling mechanism and cooling A treatment chamber where the post-gas is filtered; the waste gas cooling mechanism includes a cooling pipe 5 fixedly installed in the gas cooling chamber, and one end of the cooling pipe 5 is connected to the air inlet 11; an exhaust fan 7 is installed at the output port.

[0045] The cooling pipeline 5 is spiral; the end of the cooling pipeline 5 close to the air inlet 11 is provided with a filter 51 , and the end of the cooling pipeline 5 away from the air inlet 11 communicates with the box body 1 .

[0046] The cooling pipe 5 includes an inner tube for exhaust gas flow and an outer tube sleev...

Abstract

The invention discloses a high-temperature exhaust gas filtering apparatus. The high-temperature exhaust gas filtering apparatus is connected with an exhaust gas output pipeline and comprises a box provided with a gas inlet and a gas outlet. The interior of the box comprises a gas cooling chamber provided with an exhaust gas cooling mechanism and a processing chamber used for filtering cooled gas.The exhaust gas cooling mechanism comprises a cooling pipeline fixedly arranged in the gas cooling chamber, and one end of the cooling pipeline is connected with the gas inlet. The gas outlet is provided with an exhaust fan. The high-temperature exhaust gas filtering apparatus provided by the invention effectively cools high-temperature exhaust gas via the spiral cooling pipeline; a perforated foamed aluminum plate in the apparatus can be cyclically used and has long service life, so maintenance cost is effectively lowered; the perforated foamed aluminum filtering plate does not deform even after blowing by strong breeze and has stable filtering performance and good flame resistance; the perforated foamed aluminum filtering plate can be recycled, so air pollution is prevented; and the high-temperature exhaust gas filtering apparatus has simple structure and good practicality.

Description

technical field [0001] The invention relates to the technical field of waste gas treatment, in particular to a high-temperature waste gas filter device. Background technique [0002] Exhaust gas purification mainly refers to the work of treating industrial waste gas such as dust particles, flue gas smoke, odorous gas, and toxic and harmful gases generated in industrial places. Common waste gas purification includes factory smoke and dust waste gas purification, workshop dust waste gas purification, organic waste gas purification, waste gas odor purification, acid-base waste gas purification, chemical waste gas purification, etc. Therefore, there is a need for a waste gas treatment device with complete functions and good evolutionary effect. Nowadays, the treatment devices are relatively single, and the purification of many waste gases usually does not achieve the expected effect or does not meet the standard at all, which is not conducive to environmental protection.
