Abstract

A dredging device for a pole plate dripping pipe of a wet electrostatic precipitator is composed of the pole plate dripping pipe (1), an outer connector (2), a short pipe (3), a tee joint (6), a pipe plug (7), an inner connector (8), a valve (9), a water receiving tank (10) and a hairbrush (11); the pole plate dripping pipe (1) is connected outside the precipitator through the outer connector (2) and the short pipe (3), the tee joint (6), the pipe plug (7), the inner connector (8), the valve (9) and the water receiving tank (10) are arranged at the end of the short pipe (3), scale on the inner wall and dripping holes of the pole plate dripping pipe is cleared through the hairbrush (11) after the pipe plug (7) is taken down, and sediments in the pole plate dripping pipe (1) are discharged regularly through the valve (9). According to the technical scheme, the inner wall and the dripping holes of the pole plate dripping pipe can be effectively prevented from being blocked, and the wet electrostatic precipitator can be operated stably for a long time by cleaning the pole plate dripping pipe and discharging the scale regularly outside the precipitator.

Description

A kind of wet cottrell pole plate drips shower pipe dredges block apparatus

Technical field

The present invention relates to the deashing device of wet cottrell, be specifically related to a kind of wet cottrell pole plate and drip the thin block apparatus of shower pipe.

Technical background

Wet cottrell is a kind of for processing the cleaning equipment containing trace dust and microparticle, it is mainly used to remove containing harmful substances such as the dust in humid gas, acid mist, drop, aerosol, PM2.5, have that efficiency of dust collection height, the pressure loss be little, behaviour do simple, energy consumption is low, movement-less part, without reentrainment of dust, be operable with below flue gas dew point temperature, can be combined with other smoke gas treatment equipment, the advantage such as versatile and flexible, one of the ideal equipment of industrial smoke pollution control, the deacidification of each industrial processes, except mist in have extensive application. The use of wet cottrell is divided into charged, collection and deashing three phases, and what wet cottrell deashing adopted is current backwashing manners, makes dust remove along with the flowing of cleanout fluid; At present, the pole plate of wet cottrell cleans mainly has spray and drips pouring two ways. Drip the non-fountain pole plate cleaning ways such as pouring and there is the distinguishing features such as pole plate moisture film is uniform, it is thorough to clean, efficient energy-saving, stable, purification efficiency is high, get more and more in state, inside and outside application. But, along with being on the increase of engineer applied, also expose some problems, be concentrated mainly on pole plate because of hydropenia premature corrosion failure, the aspect such as specific collection area reduces relatively, purification efficiency die-offs. Trace it to its cause fouling not good enough mainly due to water quality, easy and the relatively low anti-blocking ability of hydraulic pressure relatively weak caused by. For the problems referred to above, it is necessary to propose a kind of new wet cottrell pole plate and drip the anti-blocking and thin stifled technique device of shower pipe.

Summary of the invention

It is contemplated that overcome wet cottrell pole plate to drip tube wall incrustation that shower pipe often occurs, drip problems such as drenching hole plug, with avoid pole plate premature corrosion, electric field run understable, affect the adverse consequencess such as purification efficiency, clean in real time, thoroughly, efficiently and the steady in a long-term of equipment runs thus being effectively ensured dust collecting pole plate.

For achieving the above object, the present invention adopts the following technical scheme that

A kind of wet cottrell pole plate drips shower pipe dredges block apparatus, it includes pole plate and drips shower pipe, coupling, short tube, threeway, pipe plug, nipple, valve, water receiving tank and hairbrush, it is characterized in that: pass through coupling, pole plate is dripped shower pipe prolongation and is connected to outside cleaner unit by short tube, it is provided with threeway in short tube end, which is provided with pipe plug and nipple, valve couples threeway by nipple, water receiving tank is arranged on below valve, opening pipe plug adopts hairbrush cleaning pole plate drip shower pipe inwall and drip the fouling drenching hole place, the deposit that pole plate drips in shower pipe is regularly discharged by valve, can effectively prevent pole plate from dripping shower pipe inwall and dripping the blocking drenching hole.

Described wet cottrell pole plate drips and is provided with continuous print low amounts flowing water in shower pipe and tube wall is rinsed for anti-blocking and thin stifled, and its valve is in opening all the time.

Described wet cottrell pole plate drips and is provided with the relatively large flowing water of continuous print at interval of a period of time in shower pipe and is rinsed tube wall blocking up for anti-blocking and thin, and during flushing, valve is opened simultaneously.

Described short tube wear housing place be provided with protection pipe it is protected, short tube and protection pipe between gap adopt Sealed casing pipe seal.

In upper art technical scheme:

This thin block apparatus except except wet cottrell pole plate drips and uses in shower pipe, also can adopting this technical scheme on spillway pipe, and it is identical that it installs and uses mode.

Cleaning and drip shower pipe inwall and drip the fouling drenching hole place, valve can be made regularly to discharge the deposit that pole plate drips in shower pipe by automatic executing agency, its actuator can by electric and pneumatic realization; Valve adopts manually and automatically mode of operation, timing controlled actuator Open valve under auto state.

Wearing at short tube protects pipe to guarantee tightly air tight set by housing place, Sealed casing pipe adopts heat-shrinkable T bush or non-metallic casing etc., and concrete form and material are not limit.

Pole plate is dripped shower pipe prolongation by coupling and short tube and is connected to outside cleaner unit by the present invention, and the pipe plug opening threeway connection realizes hairbrush cleaning, utilizes the nipple that threeway couples to realize valve opening and carries out water flushing, arranges water receiving tank simultaneously and improve purging system. This technical scheme can be prevented effectively from tube wall incrustation, drip and drench the phenomenon such as hole plug, the advantage such as have that blocking-proof result is good, not affect equipment properly functioning and convenient, practical, it is adaptable to drips the non-fountain pole plates such as pouring and drips the anti-blocking and thin of shower pipe and block up.

Below in conjunction with Figure of description, the present invention will be further described.
