Description

Multistage high-efficiency purifier

The utility model relates to combustion products---cigarette or treatment of waste gas equipment.

Boiler flue gas purification adopts wet processing more at present, and commonly used is spray type sieve-plate tower deduster, and it is made up of sieve plate and top installation spray head thereof, and when flue dust contacted with liquid on the plate by the sieve plate hole, flue dust was taken away by liquid adsorption.Another kind is Chinese patent 2050933 combined wet scrubbers, has proposed the deduster of being made up of tower body, pipeline, blower fan, sieve plate, eddy flow plate and shower nozzle.Basically also be that flue dust purifies by sieve plate, and, make liquid be thrown toward the tower wall that flow down along wall, the gas of final purification is discharged from pipeline with dust after spray section enters eddy flow plate in the tower.The deficiency of this deduster maximum is a function singleness, can only dedusting, can not in dedusting, pernicious gas be removed in the lump.

The purpose of this utility model provides a kind of boiler that is applicable to and once finishes dedusting and remove SO ₂Clarifier Deng pernicious gas.

The utility model is to realize like this.

A kind of horizontal combined wet method multi-stage, efficient clarifier, comprise casing (1), box frame (2), unload dirt device (3), mixed flow spray equipment (4), filter (5) and blower fan, it is characterized in that being provided with slow resistance diverter (6), spray tank (7), hydraulic automatic switch (8), soup injector (9) and moisture trap (10).Slow resistance diverter is installed in the mixed flow spray equipment, and moisture trap is installed in the gas outlet.Spray tank is placed in above the casing, and hydraulic automatic switch and soup injector are placed on the box frame.3～5 filters are housed in the casing, and each filter top is equipped with shower nozzle; Be provided with spray equipment between two filters; Unloading the dirt device and be installed in lower box, is an automatic sealing dust unloading wheel (11), is the wheel (see figure 7) of a band bucket.

Below in conjunction with drawings and Examples the utility model is described further.

Enter that clarifier is sprayed after filter, slow resistance diverter depositing dust, flue gas change and flow to referring to Fig. 1, Fig. 4 flue gas, slow down pressure and flow velocity and do multidirectional diffusion, through the desulfurization of soup spray mixed flow, it is poor that the dirt district is taken off in change again, makes dust, gas, water obtain fully mixing touching aggegation.Carry out final dusting and change flue gas flow direction through second filter then, again through the desulfurization of secondary soup spray mixed flow, in and pernicious gas, change that to take off the dirt district poor, make that dust, gas, water are mixed once more to touch aggegation.Carry out dedusting for the third time and change flue gas flow direction through filter again, after moisture trap, make gas, moisture from, the flue gas that is cleaned is discharged from the gas outlet, dust and waste water flow into and unload in the dirt device.

Referring to Fig. 2 as can be known the filter disc of filter be the filter disc layer that equidistantly rearranges by the V-shaped angle bar of curved surface (12), each filter is provided with 4～5 groups of filter disc layers.

V-arrangement angle bar horizontal direction on the filter disc layer is equidistant as can be known arranges or vertical direction is equidistantly arranged referring to Fig. 2, Fig. 3.

Horizontal direction will be housed in the casing equidistantly arranges the filter of filter disc layer and vertical direction is housed and equidistantly arrange the filter of filter disc layer and be used alternatingly.

Referring to Fig. 5 (a) (b) as can be known in the middle of the slow resistance diverter by two trapezoidal and two tetrahedrons (13) that the triangle steel plate is formed, skin is equipped with four trapezoidal filter discs (14), they respectively with each parallel sided of tetrahedron.

Referring to Fig. 6 moisture trap is two rotating vanes of being made up of S shape blade (15) and sharf, is installed in the gas outlet.

Referring to Fig. 8 as can be known hydraulic automatic switch by controller housing (16), overcoat (17), leakproof gland (18), valve rod (19), adjust screw (20) and UNICOM's mouth (21) is formed, wherein there is annular groove (22) at the valve rod middle part, between valve rod and adjustment screw back-moving spring (26) and spring base (27) is housed; The soup injector is made up of injector housing (23), nozzle (24), adjustment cap (25) and UNICOM's mouth (21).Soup flows into from the A mouth, and the annular groove on valve rod is regulated adjustment screw (20) valve rod is moved forward and backward to soup injector B mouth, changes the relative position of annular groove and UNICOM's mouth, the control medicinal liquid flow.Water flows into from soup injector C mouth, mixes through nozzle (24) and soup, and mixed solution is delivered to each shower nozzle place by water pipe (28), and the concentration of its solution can be regulated the adjustment cap and be determined.
