Background technology
Deduster is the important component part of station boiler dust pelletizing system, directly affects the economy and the security of station boiler unit in its performance, cost and service life.In addition, functional, cheap deduster is to improve one of the economic benefit in power station and essential condition of social benefit.The thermal power generation unit of homemade thermal power generation unit of China and early stage import mainly uses dust arresters such as gravity settling chamber, cyclone dust collectors, wet scrubber, electric cleaner, all in various degree exist the problem that some are difficult to overcome.As: the gravity settling chamber volume is big, efficient is low, can only be as the pre-dedusting device of high-efficiency dust remover; Lower, the easy obstruction of the efficient of cyclone dust collectors is had relatively high expectations to the flowability of grit in the flue gas; The wet scrubber water consumption is big, is unwell to the water-deficient area and uses; The operational reliability of electric cleaner is low, efficient is unstable.The problems referred to above cause shortcomings such as boiler dusting system dust removing efficient is low, operational reliability is poor, equipment cost height, be difficult to improve the economy and the safety inspection of boiler unit operation, and above deduster all can not adapt to more and more strict emission control standards.
The utility model content
The purpose of this utility model is for overcoming above-mentioned shortcoming, and a kind of efficiency of dust collection height, reliable, pulse flat bag deduster that operating cost is lower are provided, and it can be used in the dust pelletizing system of coal-fired power station boiler.
The technical solution of the utility model is: a kind of pulse flat bag deduster, be connected between boiler back end ductwork outlet and the exhanst gas outlet, constitute by smoke inlet, casing, rotary counter-blowing mechanism, ash bucket etc., wherein smoke inlet places wall box, is bullet, and its enlarging one side is connected with casing, establish flat bag bunch in the casing, its top and rotary counter-blowing mechanism connection, its underpart is communicated with ash bucket, adds impulse electromagnetic valve between the gas bag of rotary counter-blowing mechanism and revolution airduct.
Add orifice plate shape air-flow buffering current equalizer in the smoke inlet, vertical with the flue gas airintake direction, air-flow buffering current equalizer is 2～4 layers; The smoke inlet cross section is circular or square; Flat bag bunch is that flat bag is arranged into column with concentric circles, and flat bag cross section is oval.
The utility model beneficial effect is as follows:
1. efficiency of dust collection height.The utility model is taked the arrangement form of side air inlet, be that dusty gas enters from deduster sidewall open to the outside world formula, casing top communicates with rotary counter-blowing mechanism, pure qi (oxygen) body after the filtration is from the arrangement of deduster top emptying, adopt this arrangement SR less, and dust can fall to entering ash bucket rapidly behind the deashing, and dust second adsorption rate is little, can realize online ash removal; In addition, the flat bag bunch flat cloth bag non-rectilinear arranged in concentric circles mode of employing makes limited space reach maximum filter area, thereby improves efficiency of dust collection in the utility model casing.
2. simple in structure, reliable, operating cost is lower.The utility model adopts heavy caliber action of low-voltage pulse rotary counter-blowing, combine the advantage of rotary counter-blowing and pulse dust cleaning deduster, need not resemble the pulse dust cleaning deduster and arrange the more pulse valve of number, reduce maintenance rate, avoided the air consumption of rotary counter-blowing purge mode big, can not increase back blowing machine, make the deduster structure simpler.
3. the utility model is provided with air-flow buffering current equalizer in smoke inlet, makes the part coarse granule dust sedimentation after clashing in the ash-laden gas slip into ash bucket, avoids dust granule directly to clash into filter bag filter bag is caused damage, and the effect of protection filter bag is arranged.

The specific embodiment
Embodiment
Shown in Fig. 1～6, the utility model is connected between boiler back end ductwork outlet 9 and the exhanst gas outlet 3, by smoke inlet 1, casing 6, rotary counter-blowing mechanism 2, ash bucket 7 constitutes, smoke inlet 1 places casing 6 sidewalls, be bullet, its enlarging one side is connected with casing 6, establish flat bag bunch 61 in the casing 6, its top is communicated with rotary counter-blowing mechanism 2, its underpart is communicated with ash bucket 7, the gas bag 21 of rotary counter-blowing mechanism 2 and 24 of airducts of revolution add impulse electromagnetic valve 22, flat bag bunch 61 is that flat bag is arranged into column with concentric circles, flat bag cross section is oval, thereby reaches maximum filter area in limited space, adds two-layer orifice plate shape air-flow buffering current equalizer 11 in the smoke inlet 1,12, vertical with the flue gas airintake direction, ash discharging hole 8 is established in ash bucket 7 bottoms, and exhanst gas outlet 3 outsides are provided with wind blocking door 4, and casing 6 one sides are provided with cat ladder and inspection platform 5.
Smoke inlet 1 of the present utility model (shown in Fig. 3～5) is that two-layer air-flow buffering current equalizer 11 is equipped with in an inside; 12 bullet; portion's flow resistance is quite little within it for flue gas; ash-laden gas enters smoke inlet 1 by boiler back end ductwork outlet 9; enter smoke inlet 1 by bullet reducing one side; through being installed on the two-layer air-flow buffering current equalizer 11 of its inside; 12 enter casing 6 by bullet enlarging one side; because the sudden enlargement of passage section; make flue gas flow rate die-off part coarse granule dust in the ash-laden gas in smoke inlet 1 directly sedimentation or with air-flow buffering current equalizer 11; 12 bump back sedimentations slip into ash bucket, air-flow buffering current equalizer 11; 12 have current-sharing; the effect of protection cloth bag.
