In order to fix the position of the dust removing bag 54, a fixing groove 552 is formed in the limiting ring 551, an elastic fixing ring is arranged at the bag opening of the dust removing bag 54, the dust removing bag 54 is placed into a net, the elastic fixing ring is pressed into the fixing groove 552, displacement can be avoided, a balancing weight 541 at the bottom of the dust removing bag 54 plays a role in drainage, particles such as tar in flue gas possibly adhere to the dust removing bag 54 in a liquid form after being heated, and oil drops can smoothly fall below due to the design of the balancing weight 541.
The working principle of the utility model is as follows: when the flue gas enters the box body 1 through the air inlet pipe 3, under the cooperation of the temperature sensor 8 and the temperature control component 7, the flue gas carries out primary adsorption on dust and impurity particles through the mesh cover 55 and the dust bag 54 when upwards flowing, then carries out secondary adsorption through the secondary adsorption box 9, finally flows out from the air outlet pipe 4, when sediment is gathered to a certain extent on the mesh cover 55 and the dust bag 54, the pulse valve 512 sprays compressed gas, the mesh cover 55 is driven to vibrate together when the dust bag 54 is vibrated, the sediment is fallen off at the moment and discharged from the drain 6, when the dust bag 54 and the mesh cover 55 need to be replaced, the turnover window 10 is opened, the position of the support rod 52 is moved, the mesh cover 55 and the dust bag 54 are taken out from the upper part, a new mesh cover 55 and the dust bag 54 are replaced, then the support rod 52 is pushed back to the original position, the turnover window 10 is closed, when the active carbon in the secondary adsorption box 9 needs to be replaced, the top of the box body 1 is lifted through an escalator, the drawing-out piece 91 is pulled out, and new active carbon is pushed into the box.
