Description

Boiler exhaust gas dust arrester

Technical field

The utility model relates to a kind of dust arrester, and specifically a kind of boiler exhaust gas dust arrester, belongs to boiler dusting technical field.

Background technology

At present, along with the development of society and the raising of people's living standard, the requirement of people to environment is also more and more higher.Industrial Boiler is one of important thermal hardware involved the interests of the state and the people, and traditional Industrial Boiler is using coal as fuel, but the flue dust produced after coal combustion or dust concentration higher, big for environment pollution, therefore, in order to reduce the pollution to environment, biomass boiler arises at the historic moment.Biomass boiler is a kind of boiler, using biomass energy as fuel, although utilize biomass energy can reduce pollution to environment, if do not process boiler exhaust gas, still can produce certain flue dust or dust, produce pollute environment.The method of general employing water mist dust-removing processes boiler exhaust gas, but it is higher or at the insufficient biomass fuel of boiler combustion for the moisture as rice husk class, the boiler smoke produced is larger, traditional water mist dust-removing method cannot be clean by impurity treatment larger for particle in flue dust, therefore, the boiler exhaust gas of discharge still causes very large pollution to environment.

Summary of the invention

The utility model provides a kind of boiler exhaust gas dust arrester, can carry out dedusting effectively by the particle larger to flue dust in boiler exhaust gas, and good dedusting effect, reduce the pollution to environment further.

To achieve these goals, a kind of boiler exhaust gas dust arrester of the utility model, comprises dedusting tank, air exhauster and dirt pocket; Be provided with the first spray chamber and the second spray chamber in described dedusting tank, in described two spray chambers, be respectively equipped with high pressure spray head, bottom two spray chambers, be communicated with formation sewage storage device; Be provided with flue dust mud chamber in described dirt pocket, flue dust spray chamber and flue dust discharge chamber, described flue dust spray chamber is provided with high pressure spray head, described flue dust mud chamber, flue dust spray chamber be communicated with formation tank bottom flue dust discharge chamber; Described first spray chamber is connected to smoke-intake pipe, and described flue dust discharge chamber is connected to pipe; Second spray chamber of described dedusting tank is with air exhauster, be connected by pipeline between air exhauster and the flue dust mud chamber of dirt pocket.

Further, sewage storage device is provided with sewage effluent.

Further, tank is provided with inlet channel and drainage pipeline.

Further, tank is also provided with overfall.

Compared with prior art, the utility model flue dust enters in dedusting tank and carries out first time water mist dust-removing, flue dust after dedusting enters dirt pocket through piping again and carries out second time water mist dust-removing, altogether through twice water mist dust-removing, effectively removes impurity larger in boiler exhaust gas, make the tail gas of discharge more clean, thus significantly reduce the pollution of tail gas to environment.The utility model structure is simple, is easy to manufacture, and cost is low.

Accompanying drawing explanation

Fig. 1 is the utility model overall structure schematic diagram;

Fig. 2 is that the utility model flue dust moves towards schematic diagram.

Detailed description of the invention

Below in conjunction with accompanying drawing, the utility model is described in further detail.

As depicted in figs. 1 and 2, a kind of boiler exhaust gas dust arrester, forms primarily of dedusting tank, air exhauster 6 and dirt pocket; Described dedusting tank is made up of the first spray chamber 3 and the second spray chamber 4, is respectively equipped with bottom high pressure spray head 2, two spray chamber and is communicated with formation sewage storage device 12 in described two spray chambers; Described dirt pocket is made up of flue dust mud chamber 7, flue dust spray chamber 8 and flue dust discharge chamber 10, and described flue dust spray chamber 8 is provided with high pressure spray head 2, is communicated with formation tank 11 bottom described flue dust mud chamber 7, flue dust spray chamber 8 and flue dust discharge chamber 10; Described first spray chamber 3 is connected to smoke-intake pipe 1, and described flue dust discharge chamber 10 is connected to pipe 9; Second spray chamber 4 of described dedusting tank is with air exhauster 6, be connected by pipeline 5 between air exhauster 6 and the flue dust mud chamber 7 of dirt pocket.

For the sewage in timely effluent sewerage holder 12, prevent dedusting tank from filling sewage, sewage storage device 12 of the present utility model is provided with sewage effluent 121, so that the sewage in timely effluent sewerage holder 12.

As the improvement of the utility model to technique scheme, described tank 11 is provided with inlet channel 111 and drainage pipeline 112, and described tank 11 is also provided with overfall 113.After the water in tank 11 is by smoke contamination, discharge in time by drainage pipeline 112, and then pour into clear water by inlet channel 111, unnecessary water flows out tank 11 by overfall 113, effectively prevent the carelessness because of staff, cause clear water or sewage to fill the phenomenon of whole dirt pocket.

During work, flue dust enters the first spray chamber 3 of dedusting tank by smoke-intake pipe 1, high pressure spray head 2 pairs of flue dust spray, sewage after spray enters sewage storage device 12, flue dust after spray enters into the second spray chamber 4 by sewage storage device 12 and carries out second time spray, air exhauster 6 constantly attracts the flue dust in the second spray chamber 4, flue dust after second time spray enters the flue dust mud chamber 7 of dirt pocket by pipeline 5, and then enter flue dust spray chamber 8 by tank 11, high pressure spray head in flue dust spray chamber 82 pairs of flue dust carry out third time spray, flue dust after third time sprays enters flue dust discharge chamber 10 by tank 11 again, and discharge along pipe 9.

In addition; all some dust or impurity can be precipitated because flue dust enters in water at every turn; therefore each from water flue dust out all can be purified further; again through the spray of three sub-high pressure fountain heads 2; the flue dust of discharging is cleaner, pollution-free; reach the requirement of national environmental protection, be conducive to the protection of environment.
