Abstract
A positive pressure type bag dust collector relates to dust collectors and comprises a leg component which is provided with a bag chamber and an air inlet tube communicated with the bag chamber. The positive pressure type bag dust collector is characterized in that a backward air suction tube is connected to the lower portion of the air inlet tube and communicated with the air inlet tube through a switch valve, a dust hopper is connected to the lower portion of the bag chamber, and a gate valve is mounted at an outlet of the dust hopper. The positive pressure type bag dust collector is low in investment, high in heat resistance of the bag, convenient in maintenance, fine in effect and small in running resistance by means of separated-chamber backward air suction dust collecting.
Description
Technical field
The utility model relates to deduster, is specifically related to a kind of positive-pressure type sack cleaner.
Background technology
The material that sack cleaner is extensively applied to clean when filtering the hot stove pyrolytic semlting in ash-laden gas and ore deposit reclaims, and makes flue gas reach discharge standard.Ash-laden gas after the burning is blown into the filter bag inside of sack cleaner in the effect of air-introduced machine, and dust that contains in the flue gas in this process and recover materials are filtered the inwall that accumulates in filter bag by filter bag.What come out in the filter bag through such process is exactly clean flue gas, can be by the top smoke stack emission to upper atmosphere.As long as reasonably select the filter area of filter bag, just can reach environmental protection requirement with comparalive ease.When existing sack cleaner, dusty gas enter the deduster casing by the deduster air inlet,, do not have the locellus water conservancy diversion, cause the air-flow major part to pour in air intake body rear side, increase the filtration load of rear side filter bag because flow velocity is very big.Under the dense situation of dusty gas, can cause the local filter bag serious wear of inlet air plenum rear side, need often to change filter bag.Especially for large-scale sack cleaner,, reduce the service life of rear side filter bag because the vortex phenomenon that the air-flow skewness causes makes the resistance of deduster increase.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of running resistance little, the positive-pressure type sack cleaner that life-span of the filter bag is high.
Technical problem to be solved in the utility model realizes by the following technical solutions,
A kind of positive-pressure type sack cleaner, comprise leg assembly, the air inlet pipe that leg assembly is provided with bag chamber and is communicated with the bag chamber, it is characterized in that: described air inlet pipe bottom is connected with the back suction airduct, described back suction airduct is communicated with by a transfer valve with air inlet pipe, described bag bottom, chamber is connected with ash bucket, and the exit of ash bucket is equipped with push-pull valve.
Described bag chamber is communicated with air inlet pipe, transfer valve, back suction airduct and ash bucket.
Described bag top, chamber is equipped with top rail, access door and chimney.
Described bag top, chamber is provided with the filter bag hanging mechanism, and filter bag is hung and hung with filter bag.
The beneficial effects of the utility model are: reduced investment, and it is strong, easy to maintenance that cloth bag is high temperature resistant, adopts back suction wind sub-room cleaning mode, and effective, running resistance is little.

Fig. 2 is the utility model front view.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
As shown in Figure 1 and Figure 2, a kind of positive-pressure type sack cleaner, comprise leg assembly 1, the air inlet pipe 7 that leg assembly 1 is provided with bag chamber 3 and is communicated with bag chamber 3, air inlet pipe 7 bottoms are connected with back suction airduct 9, back suction airduct 9 is communicated with by a transfer valve 8 with air inlet pipe 7, and bag 3 bottoms, chamber are connected with ash bucket 2, and the exit of ash bucket 2 is equipped with push-pull valve 10.
Bag chamber 3 and air inlet pipe 7, transfer valve 8, back suction be in charge of 9 and ash bucket 2 is communicated with, bag 3 tops, chamber are equipped with top rail 6, access door and chimney (not marking among the figure), bag 3 tops, chamber are provided with filter bag and hang 4, filter bag is hung and is hung with filter bag 5 on 4.
