Problems solved by technology
Especially in the printing industry and coating industry, there is a lot of dust and fluff in the exhaust gas and the temperature of the gas is high. The existing exhaust gas treatment equipment is not effective for this type of exhaust gas treatment. At present, most of them use simple filter devices combined with water washing The tower purifies dust and lowers the gas temperature; however, such devices usually occupy a large area of equipment and require high equipment investment. At the same time, some organic matter in the exhaust gas will be washed and discharged by the water washing tower, causing secondary pollution

Embodiment Construction
[0014] Such as figure 1 As shown, a high-temperature exhaust gas filter device includes a housing 1 , a dust filter unit 2 , a cooling unit 3 and a honeycomb filter unit 4 . The housing 1 has an air inlet 11 and an air outlet 12 . The dust filter unit 2, cooling unit 3 and honeycomb filter unit 4 are all located in the housing 1, and the dust filter unit 2, cooling unit 3 and honeycomb filter unit 4 pass through the flange 5 in turn (see image 3 ) connection, and the dust filter unit 2 is adjacent to the air inlet 11 , and the honeycomb filter unit 4 is adjacent to the air outlet 12 .
[0015] see again figure 2 , the dust filter unit 2 includes a frame 21 and a filter layer 22 fixed on the frame 21, the dust filter unit 2 can remove most of the dust in the exhaust gas, thereby ensuring that the cooling unit 3 is not affected by the dust in the exhaust gas Dust clogged. The frame 21 can be a grid-shaped screen, so that the frame 21 can better support the filter layer 22 ...

Abstract
The invention provides a high temperature exhaust gas filtering apparatus. The apparatus comprises a shell, a dust filtering unit, a cooling unit and a honeycomb filtering unit. The shell is provided with a gas inlet and a gas outlet. The dust filtering unit, the cooling unit and the honeycomb filtering unit are respectively positioned in the shell, and the dust filtering unit, the cooling unit and the honeycomb filtering unit are sequentially connected. The apparatus has the advantages of simple structure, precise and simple parts, small occupied area, low device investment cost, removal of dusts and macromolecular organic matters from exhaust gas, and no secondary pollution.
Description
technical field [0001] The invention relates to waste gas treatment equipment, in particular to a high-temperature waste gas filtering device. Background technique [0002] The current waste gas treatment technology is becoming more and more diversified, and the mainstream treatment process "adsorption-catalytic combustion method" and "adsorption-desorption recovery method" equipment have higher requirements for the amount of dust and gas temperature in the treatment of organic waste gas. Especially in the printing industry and coating industry, there is a lot of dust and fluff in the exhaust gas and the temperature of the gas is high. The existing exhaust gas treatment equipment is not effective for this type of exhaust gas treatment. At present, most of them use simple filter devices combined with water washing The tower purifies dust and lowers the gas temperature; however, such devices usually occupy a large area of equipment and require high equipment investment. At t...
