[0028] The present invention provides a biomass charcoal waste gas purification and emission equipment and a method of using the same through improvement, and its working principle is as follows;

[0029] First, the waste gas collection point 1 can collect the waste gas, and then the waste gas enters the spray tower 3 through the first transmission pipe 2 for spray treatment, and the larger particles in the waste gas are deposited and filtered. After filtering in the spray tower 3, the waste gas will flow along the filter transmission pipe 4, and the honeycomb carbon block 45 in the filter transmission pipe 4 will perform a secondary filtration on the waste gas. Then, the waste gas that has been filtered again can enter the box 51, and the ultraviolet lamp 55 set at the right end of the inner side of the box 51 performs photo-oxidation catalysis on the waste gas;

[0030] Second, after the exhaust gas passes through the first baffle plate 56, it is concentrated in the middle of the inner side of the box body 51, and then the exhaust gas is filtered by the activated carbon in the frame body 581. After the filtration is completed, the exhaust gas will follow the second transmission pipe 6, and under the action of the fan 7, the filtered exhaust gas will rise to the top of the discharge pipe 8 for discharge;

[0031] Third, after long-term use, if the honeycomb carbon block 45 inside the tube body 41 needs to be replaced, the sealing effect between the sealing cover 42 and the tube body 41 can be released by an external tool, and the honeycomb carbon block 45 placed on the top of the grid plate 44 can be removed for replacement;

[0032] Fourth, when the activated carbon in the purification pull frame 58 needs to be replaced, the drawstring at the front end of the frame 581 can be pulled outward to make the frame 581 slide outward from the slide groove 57, and then the activated carbon in the placement frame 584 can be poured to the discharge location by flipping the frame 581 and refilled. If modular carbon blocks are needed later, the placement frame 584 can be pulled out of the limit block 583 by applying upward force, and then the carbon block can be placed on the top of the limit block 583.
