Detailed Description

Referring to fig. 1 and 2, the invention is a filter belt type dust collector capable of automatically changing cloth, which comprises a dust collector air outlet 1, a dust collector air inlet 2, an ash hopper 3, an ash discharge valve 4, a dust collector shell 5, an ash cleaner 6, a recovery drum 7 and a new belt drum 8, wherein the dust collector shell 5 is divided into a filter chamber 16 and an air purifying chamber 15, and comprises a wall plate 10, a filter bag 11, a carrier roller 12, an air inlet side plate 9 and a sealing device 14; the air inlet side plate 9 is provided with a plurality of air inlets 13 of the filter chamber; the filter belt 11 is distributed on a plurality of carrier rollers 12 in a wave shape; the filter belt 11 divides the dust remover shell 5 into an upper part and a lower part, the lower shell is a filter chamber 16, and the upper shell is an air purifying chamber 15; the left side and the right side of the filter belt 11 are connected with an air inlet side plate 9 or a dust remover wall plate 10 through a sealing device 14; the front end and the rear end of the filter belt 11 are respectively connected with a new belt drum 8 and a recovery drum 7, the new filter belt and the failure filter belt are respectively stored in the drums, and the new belt drum 8 and the recovery drum 7 both comprise rotating mechanisms.

When the invention is used for filtering flue gas, the process is as follows: the dust-containing air enters the interior of the dust remover from the air inlet 2 of the dust remover, enters the filter chambers 16 of the filter belt 11 on one side from the air inlets 13 of the filter chambers in a side air inlet mode under the negative pressure action of a fan, and the clean gas filtered by the filter belt 11 enters the air purifying chamber 15 and is exhausted to the atmosphere through the air outlet 1 of the dust remover; the dust on the surface of the filter belt 11 falls into the ash hopper 3 under the action of the ash remover 6 and is periodically discharged through the ash discharge valve 4.
