Description
Technical field
The utility model belongs to field of Environment Protection control atmosphere pollution cleaner, particularly relates to bag-type dust collecting equipment field.
Background technology
At present, the operating cleaner structural design of every profession and trade is that flue gas enters filtering area by air inlet through branch pipe(tube), manual volume damper, storage ash bucket, after smoke filtration, by card aperture clean room, pipeline, blower fan, enter atmosphere, such structural design because of dusty gas concentration high, speed is fast, increases the weight of filter bag and filters load, to filter bag quick abrasion, equipment resistance is high, and operation energy consumption is high.The pre-dust collecting technique of W shape device is thoroughly to improve flue gas to enter deduster by the pre-dust collecting technique of W shape device, and it forms pre-dust collecting structure, has improved equipment performance, has realized equipment lower resistance, low energy consumption.Because possessing in advance, equipment gathers dust, deashing time lengthening, also extended life-span of the filter bag, save operating cost.
In the middle of prior art, not yet occur utilizing W shape technology to gather dust in advance and the device of deashing.Therefore in the middle of prior art, need badly and will solve the existing technical problem of the current industry by this kind of new device,
Summary of the invention
Technical problem to be solved in the utility model is: provide a kind of W shape device pre-dust collecting technique, the pre-dust collecting technique of this W shape device is that dusty gas slows down, enters filtering area through multistage while flowing in W shape device, filters.Gas flow rates from fast to slow, is brought a series of benefits; Deduster allocation of the amount of air is reasonable, and dust remover resistance is low, and dust-collecting efficiency is high, and dust is little to filter bag wearing and tearing, and life of bag filter is long.
The pre-dust arrester installation of W shape, is characterized in that: comprise chimney valve, buffler, air inlet threeway, flue louver valve, flow distributor, W shape device, airflow filtering section, decanting zone and filtering area internal partition, filter bag assembly, clean room, decanting zone, manhole door, filter bag positioner, bypass flue, air outlet threeway;
Described chimney valve is installed on the air inlet place of bypass flue, and is positioned at the top of air inlet threeway; Described buffler is installed on the inside of bypass flue; Described flue louver valve is installed on the air outlet place of bypass flue; Described flow distributor is positioned at the bottom of W shape device; Described W shape device is connected with filter bag assembly by airflow filtering section; Described filter bag assembly is installed on the inside of filter chamber by filter bag positioner; Described clean room is installed on the top of filter bag assembly; The inside of described decanting zone is provided with decanting zone and filtering area internal partition; Described manhole door is positioned at the sidepiece of the top clean room of filter bag assembly; Described air outlet threeway is installed on flue louver valve.
Described chimney valve is reciprocating bypass structure.
The bottom of described flow distributor is provided with ash bucket.
Described filter bag assembly consists of filter bag, bag cage and three parts of filtering area.
Described air outlet threeway is connected with blower fan.
By above-mentioned design the utility model, can bring following beneficial effect: by making full use of occupation of land space and the framework of deduster, the method that adopts deduster structure mutually to mate with flow of flue gas speed, thus met optimum speed and the mode of flue dust in flowing.Can make high concentration thus, large particle diameter dust is just deposited in ash bucket and is collected before filtering area.
The utility model gas flow rates in dust removal process from fast to slow, is brought a series of benefits, and can process high concentration flue dust does not need multistage dedusting, and deduster allocation of the amount of air is reasonable, and dust remover resistance is low, and dust-collecting efficiency is high, simple in structure, and successful in advance gathers dust.The utility model dust in dust removal process is little to filter bag wearing and tearing, and life of bag filter is long.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is further described:
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the cutaway view of Fig. 1.
In figure: 1-chimney valve, 2-buffler, the threeway of 3-air inlet, 4-flue louver valve, 5-flow distributor, 6-W shape device, 7-airflow filtering section, 8-decanting zone and filtering area internal partition, 9-filter bag assembly, 10-clean room, 11-decanting zone, 12-manhole door, 13-filter bag positioner, 14-bypass flue, the threeway of 15-air outlet.
The specific embodiment
The utility model is work so as shown in the figure: the flue dust in chimney valve 1 is in zero leakage state.Chimney valve 1 is arranged on the top position of air inlet threeway 3, is installed on the air inlet place of bypass flue 14.Air outlet threeway 15 is installed on flue louver valve 4.When closing flue louver valve 4, just open the chimney valve 1 of the reciprocating bypass structure of zero leakage simultaneously, make overtemperature flue gas by air outlet threeway 15, by blower fan, enter atmosphere through bypass flue 14.
In the accompanying drawings, flow distributor 5 is positioned at the bottom of W shape device 6; W shape device 6 is connected with filter bag assembly 9 by airflow filtering section 7; Filter bag assembly 9 is installed on the inside of filter chamber by filter bag positioner 13; Clean room 10 is installed on the top of filter bag assembly 9; The inside of decanting zone 11 is provided with decanting zone and filtering area internal partition 8; Manhole door 12 is positioned at the sidepiece of the top clean room 10 of filter bag assembly 9.Normal temperature flue gas enters air inlet threeway 3 and by wind speed 15m/s, to dedusting import, drops to gradually 6m/s ash-laden gas and enter decanting zone 11 again and with speed 3m/s, through flow distributor, enter ash bucket top and flow to air-flow changeover portion 7 and enter filter bag assembly 9 and from air inlet threeway 3 to filter bag assembly 9 air velocities, by 15m/s, drop to 0.85m/s dust removal mechanism and possess sedimentation, inertia, filtration, and three kinds of mechanism are gathered dust.
