Abstract

The utility model discloses a dust-blowing device for an ash hopper of a dust-removing device and solves the problem that dust accumulating into blocks in the ash hopper can not be discharged from the ash hopper timely at present. The dust-blowing device mainly comprises three layers of air-compressing branch pipes which surround the outer side face of the ash hopper. The three layers of the compressed air branch pipes are respectively communicated with a compressed air main pipe. Each layer of the air-compressing branch pipe is connected with at least two spraying heads which penetrate the side wall of the ash hopper and can spray compressed air into the ash hopper to blow the dust. The dust-washing device is reasonable in dust-blowing point distribution, can overcome the defects that a dust-washing point is single and dust-blowing effect is poor, and is flexible and convenient to operate and economical and practical.

Description

A kind of dust collector ash hopper ash flushing device

Technical field

The utility model relates to a kind of dust collector ash hopper ash flushing device.

Background technology

Deduster is widely used in each industrial circle with characteristics such as its efficiency of dust collection height, operational management convenience and adaptability are strong.Deduster deposits dust in flue gas through high-pressure electrostatic or filtrate on dust collection plate or filtrate, when dust deposit behind certain thickness, through rapping it is shaken to fall in the ash bucket and through unloading valve etc. ash is drained, thereby reach the purpose of dedusting.But owing to reasons such as humidity of flue gas are big, equipment leaks out, make the dust caking in the ash bucket, can not in time discharge ash bucket, have a strong impact on the normal operation of deduster.In order to prevent the generation of this type situation, on the ash bucket of a lot of dedusters, vibrator, heat(ing) coil, ash poking hole and air bubble etc. have been installed all, but these device ubiquities dash the ash point single, arrange problems such as unreasonable, ash discharge poor effect.

The utility model content

The purpose of the utility model is to overcome the prior art defective, provides a kind of ash discharge effective dust collector ash hopper ash flushing device.

The technical scheme of the utility model is achieved in that a kind of dust collector ash hopper ash flushing device; Mainly form by three layer compression air arms around the ash bucket lateral surface; Three layer compression air arms are connected with pneumatic manifold respectively; Every layer compression air arm is connected with at least two shower nozzles, and shower nozzle passes the ash bucket sidewall, can in ash bucket, injecting condensed air dash ash.

Preferably, every layer compression air arm is connected with four shower nozzles, is arranged in four sides of ash bucket.

Preferably, three layer compression air arms are connected with pneumatic manifold through air valve respectively.

Preferably, three layer compression air arms are from the downward separation of following 1/2-3/5 beginning of ash bucket height.

The utility model dashes ash point connection and reasonable arrangement, can avoid dashing the ash point single, towards the bad drawback of grey effect, and flexible and convenient operation, economical and practical.

Description of drawings

Fig. 1 is the utility model structural representation.

Fig. 2 is that the compressed air arm is connected cutaway view with ash bucket.

Among the figure, the 1-pneumatic manifold; The 2-air valve; The 3-ash bucket; 4-compressed air arm; The 5-shower nozzle.

The specific embodiment

Further describe below in conjunction with accompanying drawing:

Like Fig. 1, shown in Figure 2; A kind of dust collector ash hopper ash flushing device mainly is made up of three layer compression air arms 4 around ash bucket 3 lateral surfaces, and three layer compression air arms 4 are connected with pneumatic manifold 1 through air valve 2 respectively; Every layer compression air arm 4 is connected with four shower nozzles 5; Be arranged in 3 four sides of ash bucket, shower nozzle 5 passes ash bucket 3 sidewalls, can in ash bucket 3, injecting condensed air dash ash; According to the position of the common caking of ash bucket, three layer compression air arms 4 are from the downward separation of following 1/2-3/5 beginning of ash bucket height.

During installation; Pick out a pipe as this ash flushing device source of the gas from existing compressed air reservoir, be distributed to three layer compression air arms 4, on the pneumatic manifold 1 air valve is installed through pneumatic manifold 1; Also be separately installed with air valve 2 on the compressed air arm 4; 4 parallel connections of three layer compression air arms, which partly has grey piece for ash bucket 3, just the air valve 2 of which layer is opened and is dashed ash.

Dust caking in dust collector ash hopper 3 when being difficult to normally unload ash, is at first opened the air valve on the pneumatic manifold 1; Through the mode of knocking, judge that roughly which position ash bucket 3 lumps at, opens the air valve 2 on the corresponding compressed air arm 4 at ash bucket; Compressed air is ejected in the ash bucket 3 by shower nozzle 5, and through compressed-air actuated rapid expansion, the dust that will harden breaks up; Serious like the dust caking, also can open all air valves 2 simultaneously, reach smooth and easy purpose of unloading ash.
