Due to the adoption of the structure, the specifications of the equipment are correspondingly increased and the treatment air quantity reaches 30000m<3>/h to the maximum extent; the air current uniformity of the dust-containing gas entering the inside of the ash bucket is greatly improved, the speed of air current entering the inside of the ash bucket is reduced, the service life of the filtering bag is prolonged, the raising speed of air current in each area is enabled to be lower than the dropping speed of dust and the dust collector can still remove dust when fine dust is treated.
Description
Technical field
The utility model relates to a kind of cleaner, especially relates to a kind of pulse blow filter of easy dedusting.
Background technology
DMC type pulse blow filter, it is the practical sack cleaner of a kind of high-efficiency economy, it has that floor space is little, simple in structure, maintenance management convenience, less energy consumption, smooth running, failure rate is low, efficiency of dust collection advantages of higher, though use decades, still be widely used and affirm in each industrial and mining enterprises of China.But the DMC pulse blow filter also has many deficiencies:
(1) series specification is few, and range of application is less, and the DMC pulse blow filter filter bag specification of typing is D130*2000, employing blow valve for DN25 pulse right angle, 8 filter bags of each pulse valve blowing; Have six kinds of specifications, process the air quantity maximum and be no more than 9000m
3/ h;
(2) the DMC pulse dust collector adopts 7 times air inlet structures of ash bucket as shown in Figure 1, the air velocity that enters ash bucket 7 is very fast, washing away of 6 pairs of filter bags 4 of dusty gas is larger, and air-flow is the unevenness of ash bucket 7 large (this also is the less major reason can not doing greatlyr of DMC pulse dust collector specification); Abrasion dust particularly, the wearing and tearing of indivedual filter bags 4 are large especially, often 4 life-spans of filter bag do not reach the requirement of design, in addition, for the ultrafine dust of micron order and submicron order, the dust that unit weight is lighter is because the inhomogeneities of the ash bucket 7 interior rates of climb, so that the rate of climb of ash bucket 7 some regional gas stream has surpassed the dust decrease speed, cause the deashing inefficacy and cause whole duster system failure;
(3) pulse spraying equipment 1 of DMC pulse dust collector is arranged in the casing side, although can reduce the volume of ash bucket 7 and casing, but because pulse spraying equipment 1 is in the side of casing, must increase separately an inspection platform and guardrail 9, and from the casing top to the electromagnetic impulse valve inspection platform an approximately drop of one meter being arranged, the maintenance magnetic valve is not too convenient.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of normally deashing and the wider pulse blow filter of multi-size range of application.
The technical scheme in the invention for solving the technical problem is: a kind of pulse blow filter, comprise support, support is provided with the dedusting cavity, the dedusting cavity bottom is ash bucket, the exit of ash bucket is provided with air valve, the middle part of dedusting cavity is filter chamber, filter chamber inside is provided with filter bag, the top of dedusting cavity is provided with air-purifying chamber, and a side of air-purifying chamber is provided with the pure qi (oxygen) outlet, and the pure qi (oxygen) outlet is connected with main air blower, support is provided with pulse spraying equipment, pulse spraying equipment is connected with filter bag, and a side of described dedusting cavity is provided with the dusty gas inlet tank, is provided with the inlet plenum baffle plate in dusty gas inlet tank inside.
In order to guarantee that each regional air-flow rate of climb has been lower than the dust decrease speed, described inlet plenum baffle plate is skewed.
In order to have made things convenient for the inspection and maintenance of electromagnetic impulse valve, and also reduced an inspection platform and guardrail, described pulse spraying equipment is arranged on the top of air-purifying chamber.
Further concrete, the length of described filter bag is 2450m.
In order to guarantee operating personnel in the safety of repair apparatus, the top of described air-purifying chamber is provided with guardrail.
The beneficial effects of the utility model are: adopted after the said structure, increased accordingly the specification of equipment, processed the air quantity maximum and reach 30000m
3/ h; Greatly improve dusty gas and entered the interior airflow homogeneity of ash bucket, reduced to enter the air velocity of ash bucket, reduced dust-contained airflow washing away filter bag, increased the service life of filter bag, because the rate of climb is even in the ash bucket, guarantee that each regional air-flow rate of climb has been lower than the dust decrease speed, make deduster normal deashing still when processing fine solid particle; Made things convenient for the inspection and maintenance of electromagnetic impulse valve.
