Method used

The present invention adsorption catalysis integrated waste gas purifying device first carries out preliminary filtration dust mist and odor wherein by the adsorption device inside filter and inlet pipeline when processing waste gas, more dust mist and stink in adsorption box adsorption waste gas Odor, after the exhaust gas after adsorption reaches the emission standard, it will be discharged from the chimney through the exhaust fan. If the emission standard cannot be reached, it can enter the catalytic device through the desorption tube for catalytic treatment, and the organic matter in the exhaust gas will be catalytically burned to make it meet the emission standard. It is discharged into the chimney by the desorption fan; when the adsorption box is saturated, the valves of the exhaust fan and the adsorption box are closed, and the desorption fan blows from the inlet of the adsorption box for desorption treatment, and the exhaust gas after desorption enters the catalytic device Carry out catalytic combustion treatment, and discharge after the treatment is qualified, so that the organic matter in the exhaust gas can be treated intensively, especially suitable for the treatment o...

Example Embodiment

[0012] In the following, the present invention will be further clarified with reference to the accompanying drawings and specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and not to limit the scope of the present invention. After reading the present invention, those skilled in the art will understand various aspects of the present invention. Modifications in equivalent forms fall within the scope defined by the appended claims of this application.
[0013] Such as figure 1 As shown, the present invention discloses an adsorption catalytic integrated exhaust gas purification device, which includes an exhaust gas inlet pipeline 2 provided with a filter 1, and the inlet pipeline 2 is connected to the inlets 31 of a plurality of adsorption boxes 3 connected in parallel. The outlet 32 ​​of the adsorption box 3 is connected to the chimney 6 through the valve 4 and the exhaust fan 5, and the outlet 32 ​​of these adsorption boxes is connected to the catalytic device 8 through the valve 4 and the desorption pipe 7, and the catalytic device 8 is connected to the desorption fan 9. The desorption fan 9 is connected to the inlet 31 of the adsorption box connected in parallel through the exhaust duct 10, a valve 4 is provided between the exhaust duct 10 and the inlet 31 of the adsorption box, and the exhaust duct 10 passes through at the same time The valve 4 is connected to the chimney 6, the exhaust gas inlet pipe 2 is provided with an adsorption device for absorbing dust, mist and odor, the adsorption box 3 is equipped with an activated carbon drawer 33, and the exhaust pipe and the desorption pipe A short-circuit pipe 20 with a valve 4 is short-circuited in between, and the short-circuit pipe can realize bidirectional blowing and desorption of the adsorption box by switching the valve 4 on and off.
[0014] The adsorption and catalysis integrated exhaust gas purification device of the present invention firstly filters the dust mist and odor in the filter and the adsorption device inside the inlet pipeline when processing the exhaust gas, and absorbs more dust mist and odor in the exhaust gas in the adsorption box. After the adsorbed exhaust gas reaches the emission standard, it is exhausted from the chimney through the exhaust fan. If the emission standard is not met, it can enter the catalytic device through the desorption tube for catalytic treatment, and catalytically burn the organic matter in the exhaust gas to meet the emission standard by desorption The fan is discharged into the chimney; when the adsorption box is saturated, the valves of the exhaust fan and the adsorption box are closed, and the desorption fan is blown from the inlet of the adsorption box for desorption treatment, and the desorbed exhaust gas enters the catalytic device for catalytic combustion Treatment, discharge after qualified treatment, this can concentrate the treatment of organic matter in the exhaust gas, especially suitable for the treatment of low-concentration organic exhaust gas. After the accumulated organic matter reaches a certain concentration, it will be concentrated desorption and catalytic treatment; through adsorption, catalysis or through adsorption and desorption , Catalysis or direct adsorption treatment of different concentrations and types of exhaust gas, with a wide range of treatment, suitable for use in different production environments, that is, it can treat organic matter in the exhaust gas and absorb the odor in the exhaust gas, and the structure design is reasonable. The invention can connect multiple adsorption boxes in parallel, and perform desorption treatment after a part of the adsorption boxes are saturated with adsorption, and other adsorption boxes can continue to perform adsorption work, which ensures the continuous operation of the device without intermittent; the area occupied by the device Small area, light weight, and the activated carbon drawer in the adsorption box is easy to replace. The organic gas is absorbed and concentrated by the activated carbon drawer. When the exhaust gas concentration in catalytic combustion analysis reaches more than 2000ppm, the catalytic combustion can maintain spontaneous combustion and save energy.
