Embodiment 3
[0044]The adsorber of the boiler exhaust gas purification device is provided with an activated carbon filter, a HEPA filter and a ceramic filter in sequence along the air intake direction, and the activated carbon filter is made of activated carbon filter forming material.
[0045] The manufacture method of the activated carbon filter screen of the adsorber of the boiler exhaust gas purification device comprises the following steps:
[0046] 1. Activated carbon filter screen molding material (prepared in embodiment 2) is heated to a molten state, and is sieved with a 500-mesh screen;
[0047] ②. Fill the molten material into the processing mold and keep it under 10MPa pressure for 5 minutes;
[0048] ③, naturally cool to room temperature, then demoulding to obtain the filter screen blank;
[0049] ④, put it into a heat treatment furnace for 30 minutes, and the treatment temperature is 200° C. to obtain an activated carbon filter.
