Description

The boiler fume desulfurizing and dedusting clarifier

The utility model relates to a kind of boiler exhaust gas purifier, and it belongs to a kind of boiler fume desulfurizing and dedusting clarifier.

For reducing air pollution, various boilers all need be equipped with desulfation dust-extraction device, the flue dust that utilizes various dissimilar dust arresters that boiler is discharged purifies, but owing to all not ideal enough on existing desulfation dust-extraction device is from the project organization to the dust removing effects, make in the flue gas of last discharge and still have pollution sources, environment is damaged.The desulfation dust-extraction device that uses is roughly two kinds at present: a kind of is single hose; Its single hose will be provided with fixedly deflector of multilayer in pipe, so body height, the many inconvenience of tube coupling are installed, fixedly deflector collects grey phenomenon in flue gas normal appearance in service, influence the flue gas circulation and strengthen the smoke evacuation resistance, influence water conservancy diversion time and spray mixed effect, cause dust-removal and desulfurizing efficient low, having fixedly between deflector and the simple spray does not have power to carry out hybrid separation again, so band water band dirt problem is serious in the flue gas.Another kind is two-tube joint formula, and not only there are the problems referred to above in its two-tube joint, and it also increases labour intensity and difficulty simultaneously, also will install communicating pipe between two pipes, and its two-tube floor space is big, need improve just and can install existing boiler room.The height of single tube also is the common problem that existing boiler is not easy to install.

The purpose of this utility model is to provide a kind of boiler fume desulfurizing and dedusting clarifier, and this clarifier volume is little, and desulfurization and dedusting is effective, is convenient to install, and saves material.

Above-mentioned purpose is achieved through the following technical solutions: a kind of boiler fume desulfurizing and dedusting clarifier is characterized in that this clarifier is made of universal joint, purifying tube and dust collecting box; Its universal joint has into mouth and mouth spray; Purifying tube is built-in with the cylinder of configuration mixed flow separator; Dust collecting box leaves overflow valve, discharge outlet, measurement window and shoot door; Universal joint advances mouth through cardo ring and cylinder in the clarifier and is connected; Clarifier fixes with ring flange and dust collecting box.

It is identical that described universal joint outlet flue internal diameter and cylinder advance the mouth internal diameter, and weldering system one external diameter and cylinder advance the cardo ring that the mouth internal diameter is complementary in its universal joint outlet flue.

Described mixed flow separator with place support in the cylinder for axially to be connected; Its mixed flow separator upper surface is shaped on some deflectors.

Can establish multilayer mixed flow separator in the described cylinder.

Described purifying tube upper side wall has outlet flue.

Characteristics of the present utility model are: the clarifier overall volume is little, universal joint advances mouth and can adjust direction according to the needs of boiler exhaust gas mouth, and the mixed flow separator is at flue gas.The effect of spray liquid and air-introduced machine rotation down effectively mixes flue gas and spray liquid, and carries out gas-liquid separation with deflector, has improved the desulfurization and dedusting effect; The lime-ash of dust collecting box utilizes probe to detect by measurement window can be in time from shoot door cleaning lime-ash.The utility model is simple in structure, saves material, and floor space is little, the clarifier whole height is little, is suitable for being installed in the various existing boiler rooms and uses.

Below in conjunction with accompanying drawing in detail the utility model embodiment is described in detail:

1 one kinds of boiler fume desulfurizing and dedusting clarifiers of accompanying drawing structural representation.

Accompanying drawing 2 mixed flow cyclone separator arrangement schematic diagrames.

As shown in Figure 1, to after welding with support 11, made dust collecting box 9 lie against ground as scheming, purifying tube 16 and ash-collecting tube 9 usefulness ring flanges 12 fix, universal joint 2 is universal the connection with cylinder 5 footpath cardo rings 3, when flue gas is discharged fume in the mouth 15 from advancing of universal joint 2, lead in the other circulating water pool of clarifier alkaline spray liquid that people's pH value reaches 9-12 through water pump beat to mouth spray 1 and and in flue gas together falls into cylinder 5 and through be fixed in cylinder 5 in support 7 be that the axial ground floor mixed flow separator that is connected 6 moves guide vane 6 at air-introduced machine in it, the effect of flue gas and spray liquid is rotated automatically down flue gas and spray liquid is fully mixed, sulfur in smoke is mixed with spray liquid and abundant reacting generating salt and sulfurous acid solution, in the rotation process of mixed flow separator to the further washing, purifying of the particle in the flue gas, particle sulfate and sulfurous acid solution in the flue gas are flowed downward in splashing into dust collecting box 9 on the inwall that drains into cylinder 5 under the effect of mixed flow separator 6 and along inwall, and the flue gas of continuation operation downwards and spray liquid are through second layer mixed flow separator 6 time, be rotated mixing once more, purify and reaction, and under the effect of mixed flow separator 6, do gas-liquid separation, make sulfate and sulfurous acid solution drain into the inwall of cylinder 5 and flow downward in flowing into dust collecting box 9 along inwall, and the flue gas that purifies twice moves to the water surface in the dust collecting box 9 downwards, finishes impulse water surface purifying process after purifying tube 16 upwards moves to outlet flue 4 and sends into smoke discharging pipe.

Splash into sulfate, sulfurous acid solution, dust and spray liquid in the dust collecting box 9 downwards in dust collecting box 9 after the sedimentation separation through cylinder 5 inwalls, its lime-ash is sink at the bottom of the case, solution floats on the surface, when solution and ash deposition are a certain amount of, its solution to discharge outlet 13 places can discharge dust collecting box 9 automatically and flow into circulating water pool, when surveying its lime-ash overfill by measurement window 8 with probe, open overflow valve 14 swimming in the dust collecting box 9 put only, open shoot door 10 removing lime-ash then and get final product.

As shown in Figure 2, on mixed flow separator 6, install deflector 17 additional, can make pneumatic guide vane 6 utilize deflector 17 that the mixture of flue gas and spray liquid is beaten inwall to cylinder 5 when rotated, make gas, liquid separate more thorough.
