Description
Technical field
The invention belongs to field of Environment Protection control atmosphere pollution cleaner, particularly relate 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 air volume control valve, storage ash bucket, air is entered by card aperture clean room, pipeline, blower fan after smoke filtration, such structural design because of dusty gas concentration high, speed is fast, increases the weight of sock filtration 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 thoroughly improves flue gas to enter through the pre-dust collecting technique of W shape device after deduster, and it forms pre-dust collecting structure, improves equipment performance, achieves equipment lower resistance, low energy consumption.Gather dust in advance because equipment possesses, deashing time lengthening, also extend 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 need badly in the middle of prior art and this kind of new device will solve technical problem existing for the current industry,
Summary of the invention
Technical problem to be solved by this invention is: provide a kind of W shape device pre-dust collecting technique, and the pre-dust collecting technique of this W shape device is that dusty gas slows down through multistage, enters filtering area when flowing in W shape device, filters.Gas flow rates from fast to slow, brings a series of benefit; 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 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 is made up of filter bag, bag cage and filtering area three parts.
Described air outlet threeway is connected with blower fan.
Following beneficial effect can be brought: by making full use of occupation of land space and the framework of deduster by above-mentioned design the present invention, adopt the method that deduster structure is mated mutually with flow of flue gas speed, thus meet the optimum speed of flue dust in flowing and mode.Can make high concentration thus, Large stone dust is just deposited in ash bucket and is collected before filtering area.
The present invention's gas flow rates in dust removal process from fast to slow, brings a series of benefit, 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, and structure is simple, and gather dust successful in advance.The present invention's 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 present invention is further illustrated:
Fig. 1 is structural representation of the present invention.
Fig. 2 is the sectional 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.
Detailed description of the invention
The present invention 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 of bypass flue 14.Air outlet threeway 15 is installed on flue louver valve 4.When closing flue louver valve 4, just opening the chimney valve 1 of the reciprocating bypass structure of zero leakage simultaneously, making overtemperature flue gas enter air by air outlet threeway 15 by blower fan 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 drops to 6m/s ash-laden gas by wind speed 15m/s gradually to dedusting import and enter decanting zone 11 again and enter ash bucket top with speed 3m/s through flow distributor and flow to flow transition section 7 and enter filter bag assembly 9 and drop to 0.85m/s dust removal mechanism to filter bag assembly 9 air velocity by 15m/s from air inlet threeway 3 and possess sedimentation, inertia, filtration, and three kinds of mechanism are gathered dust.
Slow down through multistage, enter filtering area when fume gases flows in the pre-dust arrester installation of W shape, filter.Present invention achieves the technique effect of equipment lower resistance, low energy consumption in sum, therefore also extend the service life of filter bag, save operating cost and the cost of dedusting work.
