Description

The pulse blowing bag type dust precipitator that disperses the overflow card

Technical field:

The utility model relates to a kind of pulse blowing bag type dust precipitator, particularly relates to a kind of pulse blowing bag type dust precipitator that disperses the overflow card.

Background technology:

When using pulse blowing bag type dust precipitator that the smoke pollution of high temperature, high humidity and high dew point is handled; usually having condensed water in clean room produces; formed condensed water promptly trickles to card from top to bottom from inwall; flow in filter bag and the filter bag along going downstream on the card again; thus; filter bag is subjected to promptly to have increased behind the water intrusion filtration resistance of filter bag, has influenced the disposal ability to later smoke pollution, and filter effect and treatment effeciency are reduced greatly.

Summary of the invention:

The purpose of this utility model is the pulse blowing bag type dust precipitator that a kind of improved dispersion overflow card will be provided, it not only can be got rid of at the condensed water of being put aside on the card outside casing effectively, make pulse blowing bag type dust precipitator keep sealing state again, and, avoided filter bag to meet with the intrusion of condensed water.

Solution of the present utility model to achieve the above object is: the pulse blowing bag type dust precipitator of dispersion overflow card of the present utility model has an ash bucket, the end, lower end of described ash bucket is equipped with a unloading valve, described ash bucket is equiped with a casing by steel frame on the end face of ash bucket upper end, the end, upper end of casing is a clean room, be equipped with a pulse jet part on the end face of described clean room upper end, the left end sidewall of described casing is provided with dusty gas inlet, the right-hand member sidewall of described casing is provided with a purified gas outlet that communicates with clean room by the pipeline in the casing, described clean room is divided into a left side by the wooden partition of centre, right clean room, a described left side, be equipped with and winding-up pipe band spout that be communicated with in the right clean room with the pulse valve of pulse jet part, a described left side, the bottom surface of right clean room is a card with holes, be installed on the filter bag of band filter bag cage bone in the hole of described card, the filter bag of band filter bag cage bone is to hang in the casing, the left side of described clean room, the periphery of the card on the right clean room bottom surface respectively and be provided with the overflow launder that is respectively equipped with a drainage hole on that connect and the bottom surface between the inwall of casing and the wooden partition, drainage hole on the described overflow launder bottom surface passes a described casing left side with an end respectively, the overflow pipe installing hole on the right-hand member sidewall and that be ' U ' shape forms and is connected and fixed, and described overflow pipe and described installing hole place form to be connected and fixed.

Because the utility model has improved existing pulse blowing bag type dust precipitator, the periphery of the card on described left and right clean room bottom surface respectively and be provided with one between the inwall of casing and the wooden partition and disperse overflow card device, pulse blowing bag type dust precipitator is being kept under the sealing state, outwards get rid of the condensed water of assembling on the card, and stoped the condensed water on the card to flow in the filter bag, thereby, guaranteed that pulse blowing bag type dust precipitator carries out normal handling work to the smoke pollution of high temperature, high humidity and high dew point.

Description of drawings:

Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.

Fig. 1 is the structural representation of the pulse blowing bag type dust precipitator of dispersion overflow card of the present utility model.

Fig. 2 is that schematic diagram is looked on the left side of Fig. 1.

Fig. 3 is the generalized section along A-A line among Fig. 1.

Fig. 4 is the local enlarged diagram of overflow pipe of the pulse blowing bag type dust precipitator of dispersion overflow card of the present utility model.

The specific embodiment:

Below with reference to accompanying drawing the pulse blowing bag type dust precipitator of dispersion overflow card of the present utility model is made following detailed description.

Referring to Fig. 1, Fig. 2, Fig. 3 and Fig. 4, the pulse blowing bag type dust precipitator of the dispersion overflow card of this utility model is made up of ash bucket (2), casing (4), clean room (5) and pulse jet part (6).

The end, lower end of described ash bucket (2) is equiped with a unloading valve (1), by steel frame (3) casing (4) is installed on the upper end end face of described ash bucket (2), the end, upper end of described casing (4) is a clean room (5), be equipped with pulse jet part (6) on the end face of described clean room (5) upper end, the left end sidewall of described casing (4) is provided with dusty gas inlet (7), the right-hand member sidewall of described casing (4) is provided with a purified gas outlet (8) that communicates with described clean room (5) by the pipeline in the described casing (4), and described clean room (5) is by the wooden partition of centre

(9) be divided into a left side, right clean room, a described left side, respectively be provided with a winding-up pipe (10) that is communicated with the pulse valve of described pulse jet part (6) in the right clean room, be fixed with spout on the described winding-up pipe (10), a described left side, the bottom surface of right clean room is a card (11) with holes, (12), described card (11), (12) be placed with the filter bag (13) of band filter bag cage bone in the hole on, the filter bag (13) of described band filter bag cage bone is to hang in the described casing (4), the left side of described clean room (5), described card (11) on the right clean room bottom surface, (12) periphery respectively and be provided with an overflow launder that connects (16) between the inwall of described casing (4) and the wooden partition (9), (17), described overflow launder (16), (17) respectively be provided with a drainage hole (14) on the bottom surface, (15), described overflow launder (16);
