Abstract

The utility model relates to a wet cleaner matching with industrial boilers and industrial furnaces, which is composed of an outer shell, a guide plate, an atomizing chamber and a reservoir. The shape of the atomizing chamber is a curved surface. A fog drop collector is arranged between an exit port and the top of the outer shell, the guide plate is fixed on the middle upper part, and a reaction tank is arranged on the lower part. The top of the outer shell is provided with a by-pass channel which is communicated with a flue outlet. The utility model can make flue gases pass through multi-stage filtration, can simultaneously remove dust and remove sulfur and nitrogen, and has more than 95% dust removing effect and more than 75% sulfur and nitrogen removing. Boilers are without puffing after blowing out.

Description

The eddy current type flue gas cleaner

The utility model relates to a kind of environment protection equipment, the clarifier that especially matches with Industrial Boiler and Industrial Stoves and use.

At present, industrial boilers in China is burnt the flue dust that coal produced, and annual emissions has reached more than 500 ten thousand tons, flyash in the flue dust, sulfur dioxide, nitrogen oxide, harmful substances such as carbon monoxide and hydrogen sulfide, chromium, lead are discharged to the atmosphere severe contamination atmosphere, harm humans health.Therefore the flue dust of Industrial Boiler discharging has become big public hazards, is badly in need of being administered.In recent years, the deduster of various purification flue dust is come out one after another, have electrostatic, dry type, ultrasonic type and wet type, particularly wet cleaner has solved the smoke contamination problem preferably, but still that ubiquity efficiency of dust collection is not high, easily falls cigarette, corrosive pipeline after the blowing out to block more serious, the running expense height causes defectives such as secondary water pollution.

The purpose of this utility model is to provide a kind of and has smoke abatement and dust control, reduces noise, the wet cleaner of reversing smoke free during blowing out is finished in desulfurization, denitrogenation etc. simultaneously.

The utility model is realized in the following manner: this eddy current type flue gas cleaner is made up of shell, deflector, spray chamber, reservoir etc., its spray chamber be shaped as a curved surface, establish a droplet gatherer between the top of exit and shell, the middle and upper part fixes 1 to a plurality of deflectors, the bottom is as reaction tank, the end face of shell has a bypass channel, communicates with outlet flue.

Above-mentioned spray chamber be shaped as hexagon or garden arc, deflector be shaped as planar shaped or herringbone, and the herringbone angle of deflector is adjusted in 0～45 ° of scope, the droplet gatherer be shaped as rectangle or garden cylindricality, each parts adopts and mixes brick, steel plate or the cement system of giving and make and carry out preservative treatment.

Employing the utlity model has simple in structure, cheap, use easy to maintenance, characteristics such as the life-span is long, its flue gas ash removal rate is more than 95%, and sulphur, nitrogen dust removal efficiency are more than 75%, lingemann blackness is below 1 grade, reducing the unit noise more than 5～10 decibels than similar wet type, alleviated operating personnel's live load, is desirable wet type flue gas purifying equipment.

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.

Fig. 1 is the schematic diagram of first specific embodiment of the present utility model;

Fig. 2 is the schematic diagram of another specific embodiment of the present utility model.

Wet cleaner shown in Figure 1, shell (1) is a rectangular structure, inner chamber is as spray chamber, be hexagon, have a plurality of through holes between shell (1) and the spray chamber (3), the intake valve (7) of flue gas is installed respectively, blast pipe (5), bypass airduct control valve (2), purify water pipe (10), scum pipe (9) and droplet gatherer (6), spaced two herringbone deflectors (4) are fixed in the middle and upper part of spray chamber (3), the herringbone angle can be adjusted in 0～45 ° of scope, fix the droplet gatherer (6) of a rectangle grizzly bar shape between the top of the outlet of spray chamber (3) and shell (1), the bottom of spray chamber (3) is reaction tank (11), interior injection running water adds appropriate bases or the acidic materials conduct is purified waste water, reaction tank (11) links to each other by the water receiver (8) of water inlet pipe and water outlet pipe (10) with the outside, recycle for purifying waste water, the height of water level is controlled by liquid level gauge (12).During work, the high speed smoke of being introduced by air-introduced machine flows, enters spray chamber (3) through flue gas control valve (17), change to flow to and pour reaction tank (11), the flue dust flow velocity is reduced, all the other most of granule dusts are at the bottom of the gravity effect is lowered into the pond, fully mix with purifying waste water the drop, liquid film and the bubble that disperse the back to produce disposable separate to inhale float on the liquid level, and the flue gas that is cleaned is under the secondary guide effect of deflector (4), slow down and discharge through (5) by the filtration once more of droplet gatherer (6), the circulation water purification then flows to from water inlet pipe (10).

Fig. 2 has provided the structure of another kind of wet cleaner, the spray chamber of this clarifier (3) inwall is a garden arc, deflector (4) is horizontally fixed on the middle and upper part of spray chamber (3), having a plurality of aperture cross sections on the plate is the garden arc, and the droplet gatherer that is contained in spray chamber (3) exit is an annular grizzly bar.

The inwall of spray chamber (3) also can be made taper, ellipse garden shape or other shape according to need of work.

Several important materials of part in addition: 1. cement prefab, steel plate or brick mix structure manufacturing all can be adopted in shell (1), spray chamber (3), deflector (4), pond (11), and carry out preservative treatment, 2. flue (5) and water inlet pipe and water outlet pipe all adopt igelite or the steel plate manufacturing after preservative treatment.
