Abstract
A wear-resistant furnace bag-type dust collector belongs to the technical field of environment-friendly equipment, and aims to provide a wear-resistant impulse blowing bag dust collector. The technical key includes that on the basis of the existing impulse blowing bag dust collector, a guide plate (11) is arranged on a dust hopper (1) below each filtering chamber (8), and spaces of air flow expansion chambers (7) are additionally arranged above the guide plate and below a filter bag. Extending seams (4) are arranged among the filtering chambers (8), thereby forming air flow buffer areas in the filtering chambers, avoiding high-friction areas of air flow at the inlet, not only being favorable for dust removal but effectively reducing erosive wear of dust particles to the filter bag. Simultaneously, the spaces of the air flow expansion chambers further resolve the problem that an identical bag is uneven in distribution of air flow, thereby homogenizing smoke rising speed and preventing swinging and impacting of the filter bag. The extending seams are arranged among the filtering chambers, thereby preventing that steels which are expanded by heat generate heat stress to crack welding seams of a partition board inside the dust collector to cause problems of mutual wind leakage among filtering chambers and failure of dust removal.
Description
Technical field
The utility model relates to a kind of pulse blowing bag type dust precipitator that is used for the Industrial Stoves flue gas ash removal, belongs to the environmental protection equipment technical field.
Background technology
In recent years, sack cleaner since advantage such as it is safe and reliable to operation, efficiency of dust collection is high, applicability is strong be used widely at Industrial Stoves flue gas ash removal and desulfuration field.
Industrial Stoves dust in flue gas particle mainly is a clinker as the dust granules in the cement kiln head grog grate cooler lingering remnants of past customs, and hardness is big, and the surface is angular, and chiseling property of mill is stronger; Coal-fired boiler in power plant dust in flue gas particle mainly is a silica, has abrasiveness.These high abrasiveness dust granules wash away strongly to filter bag, cause life-span of the filter bag to shorten greatly.
The kiln bag dust collector generally moves under the condition of high temperature, the steel expanded by heating, and the thermal stress of generation causes mutual string wind between bag chamber easily with the drawing crack of bag dust collector internal partition weld seam, and deashing lost efficacy.
Summary of the invention
The purpose of this utility model provides a kind of abrasionproof type pulse jet bag dust collector that has.
Its technical scheme is: a kind of abrasionproof type pulse jet bag dust collector, comprise casing, be arranged in the casing by the chamber dividing plate and be installed in a plurality of filter chambers that the filter bag on the card constitutes, by the air-purifying chamber that forms between card and the casing top, the air inlet flue that constitutes by the air channel dividing plate and the flue of giving vent to anger, in the air-purifying chamber of each filter chamber, be provided with by electromagnetic impulse valve, tube connector, the pulse jetting deashing mechanism that winding-up pipe and nozzle sets constitute, be arranged on the pneumatic power lifting valve at place, air-purifying chamber gas outlet, be arranged on the control valve at air inlet place, filter chamber, and the ash bucket that is arranged on each below, filter chamber, it is characterized in that: on the ash bucket of described each below, filter chamber deflector is set, the deflector top, the filter bag below has additional space, flow expansion chamber.
Leave the expansion joint between above-mentioned each filter chamber by the isolation of chamber dividing plate.
Its technique effect is: since above the ash bucket, have additional space, flow expansion chamber below the filter bag, so in the filter chamber, formed the air-flow buffering area, avoided the height friction district of inlet air flow, both be beneficial to the sedimentation of dust, effectively alleviated the erosive wear of dust granules again filter bag; Simultaneously, space, flow expansion chamber has also solved the problem of same bag chamber distribution of air flow inequality, homogenizing the speed that rises of flue gas, prevented the swing and the collision of filter bag.Leave the expansion joint between each filter chamber, when having prevented that the kiln bag dust collector from moving under the condition of high temperature, the steel expanded by heating produces thermal stress with the drawing crack of deduster internal partition weld seam, causes the problem that mutual string wind, deashing lost efficacy between the filter chamber.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the left view of Fig. 1.
The specific embodiment
As Fig. 1, shown in 2, abrasionproof type pulse jet bag dust collector, comprise casing, be arranged in the casing by the chamber dividing plate and be installed in a plurality of filter chambers 8 that the filter bag on the card constitutes, by the air-purifying chamber 3 that forms between card and the casing top, the air inlet flue 2 that constitutes by the air channel dividing plate and the flue 6 of giving vent to anger, in the air-purifying chamber of each filter chamber, be provided with by electromagnetic impulse valve, tube connector, the pulse jetting deashing mechanism 5 that winding-up pipe and nozzle sets constitute, be arranged on the pneumatic power lifting valve 9 at place, air-purifying chamber gas outlet, be arranged on the control valve 10 at air inlet place, filter chamber, and the ash bucket 1 that is arranged on each below, filter chamber.On the ash bucket of each below, filter chamber deflector 11 is set, deflector top, filter bag below have additional space, flow expansion chamber 7.Form the air-flow buffering area, avoid the high friction of inlet air flow district, both be beneficial to dust settling, effectively alleviate the erosive wear of dust granules again filter bag; Simultaneously, space, flow expansion chamber has also solved the uneven problem of same bag chamber distribution of air flow, homogenizing the flue gas rate of climb, prevented the swing and the collision of filter bag.
Leave expansion joint 4 between above-mentioned each filter chamber by the isolation of chamber dividing plate, when preventing that the kiln bag dust collector from moving under the condition of high temperature, the steel expanded by heating produces thermal stress with the drawing crack of deduster internal partition weld seam, cause mutual string wind between bag chamber, the problem that deashing lost efficacy.
Its operation principle: the high temperature dust flue gas by the guiding device in air inlet flue and the ash bucket, enters the flow expansion chamber from air inlet, and crude particle dust falls in the ash bucket.Particle dust enters in the filter chamber with the air-flow after the homogenizing of flow expansion chamber, and after being filtered by filter bag, clean gas enters air-purifying chamber, is discharged by gas outlet, discharge duct.Dust is attracted to the filter bag surface, continuity along with filtration time, the dust layer on filter bag surface constantly thickens, resistance of the filter bag increases, when resistance reaches in advance setting value, PLC deashing control system is sent signal, at first order the gas outlet pneumatic power lifting valve of a filter chamber to be closed to cut off the filtered airflow of this chamber, then provide the instruction unpack electromagnetic impulse valve, compressed air is with the extremely short time, spray into to filter bag by winding-up pipe and drainage nozzles, because compressed-air actuated inducing action sucks filter bag to net air a large amount of in the pure qi (oxygen) case, the inverted draft of generation makes filter bag begin in proper order to expand from top to bottom, and the position that reaches capacity in proper order, produce backward acceleration this moment again under the effect of filter bag tension force, filter bag produces the dither distortion, and the adsorbed dirt cake distortion in the filter bag outside is come off.Behind the dust settling certain hour, the gas outlet pneumatic power lifting valve is opened, and this filter chamber is in the filtration state once more, and next filter chamber then enters the deashing state.So go round and begin again, the dust-precipitator resistance is in the certain value scope all the time, realize long-term continous-stable operation.According to the deduster running resistance, also can adopt line pulse jetting deashing mode.
