Abstract

The utility model relates to a dust removal device for boiler exhaust gas; the utility model belongs to the technical field of boiler fabrication. The device is composed of a draught fan, a main flue, branch flues, a dust removal tank, a cold water pipeline, a sewage discharge pipeline, a smoke discharge pipeline, an inactive mode water and vapor separator and a chimney. The utility model is characterized in that boiler smoke and dust are processed by the draught fan and are blown into multiple branch flues to lead to the dust removal tank, and water or alkaline water are installed in the dust removal tank; after being processed by a filter screen and a smoke, dust and water mixer, the boiler smoke and dust are discharged into the atmosphere through the smoke discharge pipeline, the draught fan and the inactive mode water and vapor separator. The utility model has the advantage that effects of dust removal and smoke elimination are favorable.

Description

The boiler waste gas dust arrester

The utility model relates to a kind of smoke dust in boiler dust arrester, belongs to boiler manufacturing technology field.

At present, boiler is directly to discharge flue dust, major polluting atmosphere environment by chimney in atmosphere mostly both at home and abroad.In No. 97111072.7 patents of invention, adopted following technology for effectively eliminating the volume of smoke that boiler discharges: the flue dust that the boiler exhaust gas mouth is got rid of by air-introduced machine introduce the dedusting tank of water or buck is housed after, by water or buck the pernicious gas and the soot dust granule that contain in the flue dust are disposed, reach the purpose that purifies flue dust, but flue dust directly enters in water or the buck, because of can not fully contacting with water, clean-up effect is undesirable.In No. 91100986.8 patents of invention, flue dust mainly is to purify flue dust by a flue dust one water agitating device, though also can increase the contact area of flue dust and water, has improved dust removing effects, and dust removing effects is still undesirable.

The purpose of this utility model is exactly for the flue dust that can prevent that overcomes above-mentioned shortcoming and provide forms air pocket in water, and flue dust is fully contacted with water, improves a kind of boiler waste gas dust arrester of dust removing effects.

The purpose of this utility model is achieved in that this device is by air-introduced machine, flue collector, branch flue, dedusting tank, cold water pipes, blow-off line, smoke discharging pipe, passive type moisture separator and chimney constitute, the 1# air-introduced machine is connected with the boiler gas outlet by pipeline one end, one end links to each other with flue collector, flue collector one end links to each other with the 1# air-introduced machine, the other end links to each other with dedusting tank, branch flue one end links to each other with flue collector, the other end links to each other with dedusting tank, water or low concentration buck are housed in the dedusting tank, there is the gas outlet upper end, 2# air-introduced machine one end links to each other with smoke discharging pipe, the other end links to each other with the passive type moisture separator, passive type moisture separator one end links to each other with the 2# air-introduced machine, the other end links to each other with chimney by pipeline, cigarette after the udst separation is entered in the air, wherein flue collector is than the relative position height of water in the dedusting tank, there is blowoff valve the dedusting tank lower end, blowoff valve links to each other with blow-off line regularly dirty slag, sewage discharge is in cesspool, in the dedusting tank upper end cold water pipes water inlet pipe is arranged, regularly cold water is introduced in the dedusting tank.

Be connected with the multichannel branch flue between flue collector and the dedusting tank, flue dust one water agitator is installed in the dedusting tank, it is made of rotating shaft and blade, the following one deck filter screen in addition of flue dust-water agitator.

Compared with prior art the utility model has the advantages that: structure is simpler, and the dedusting smoke effect is good, can reclaim a part of utility, alleviates the pollution to atmosphere, the no black smoke discharging of basic realization.

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

Fig. 1 is a structure chart of the present utility model.

Wherein: 1-boiler, 2-1# air-introduced machine, 3-flue collector, 4-branch flue, 5-dedusting tank, 6-cold water pipes, 7-blow-off line, 8-smoke discharging pipe, 9-2# air-introduced machine, 10-passive type moisture separator, 11-chimney, 12-blowoff valve, 13-filter screen, 14-flue dust-water agitator, 15-smokestack.

The utility model device is by air-introduced machine [2], flue collector [3], branch flue [4], dedusting tank [5], cold water pipes [6], blow-off line [7], smoke discharging pipe [8], passive type moisture separator [10], chimney formations such as [11], the boiler exhaust gas mouth links to each other with 1# air-introduced machine [2] by a pipeline, flue collector [3] one ends link to each other with 1# air-introduced machine [2], the other end links to each other with branch flue [4], branch flue [4] one ends link to each other with flue collector [3], the other end links to each other with dedusting tank [5], inject water or low concentration buck in the dedusting tank [5], there is the gas outlet upper end, 2# air-introduced machine [9] one ends link to each other with the gas outlet, the other end links to each other with passive type moisture separator [10], passive type moisture separator [10] one ends link to each other with 2# air-introduced machine [9], the other end links to each other with chimney [11] by smoke discharging pipe, rely on the wind-force of discharging gas to promote passive type moisture separator [10], the part water or the impurity that still contain in the discharge gas are separated with gas, and the cigarette after the udst separation entered in the air by chimney [11], wherein flue collector [3] is higher than the relative position of the middle water of dedusting tank [5], there is blowoff valve [12] dedusting tank [5] lower end, blowoff valve [12] links to each other with blow-off line [7] regularly dirty slag, sewage discharge is in cesspool, in dedusting tank [5] upper end cold water pipes [6] water inlet pipe is arranged, regularly cold water is introduced in the dedusting tank [5].The flue dust of being sent here by 1# air-introduced machine [2] enters branch flue [4] through flue collector [3], send into dedusting tank [5] from dedusting tank [5] bottom after being divided into several parts here, at first pass through one deck filter screen [13] air pocket is divided into minute bubbles, passing through flue dust-water agitator [14] again stirs, make the water of rotation that minute bubbles are broken into more, littler minute bubbles, with time of contact and the contact area of increase with water.Flue dust is through after so filtering, and the water surface of emerging be discharged in the air through smoke discharging pipe [8], 2# air-introduced machine [9], passive type moisture separator [10], chimney [11], and flue dust is deposited in the dedusting tank [5], and sediment and sewage are discharged from blowoff valve [12].For medium small boiler, also can only use an air-introduced machine.
