Description
Technical field
The utility model relates to the boiler plant application, and the tail gas that particularly relates to boiler carries out denitrification apparatus.
Background technology
Boiler is a kind of energy conversion, to the energy of boiler input the forms such as heat energy of chemical energy in the fuel, electric energy, high-temperature flue gas are arranged, and through the boiler conversion, outwards output has steam, high-temperature water or the organic heat carrier of certain heat energy.The original meaning of pot refers to the water container that heats at fire, and stove refers to the place of combustion fuel, and boiler comprises pot and stove two large divisions.The hot water that produces in the boiler or steam can be directly for industrial production and people's lives provide required heat energy, also can be converted to mechanical energy by Steam Power Equipment, or by generator mechanical energy is converted to electric energy again.Provide the boiler of hot water to be called hot-water boiler, be mainly used in life, a small amount of application is also arranged in the industrial production.The boiler that produces steam is called steam boiler, and is often referred to as boiler, multiplex in thermal power station, boats and ships, locomotive and industrial and mining enterprises.Boiler carries out simultaneously at " pot " and " stove " two parts, and water enters after the boiler, and boiler heating surface makes water be heated into hot water or the generating steam of uniform temperature and pressure in the heat transferred water that absorbs in boiler circuit, is drawn application.In the combustion apparatus part, heat is constantly emitted in fuel combustion, and the high-temperature flue gas that burning produces is by the propagation of heat, and with the heat transferred boiler heating surface, and self-temperature reduces gradually, is discharged by chimney at last.
Yet along with the continuous development of society, the pollution of air is also in suitable lifting, and administering now environment also is a vital task of country, yet after the energy burnt in the boiler, many NO were contained in tail gas the inside
XAnd cause a large amount of environment to pollute, had a strong impact on resident's normal life, and that the workload of company does not have equally is upper as to go, and the object of tail gas the inside being wasted in the air in vain, but all do not use, also be a kind of loss to the energy, serious increase the cost of processing, simultaneously, also improved workman's labour intensity, also endangering the healthy of people, also is very large destruction to environment, does not meet the demand of presentization development.
In sum, for the defective of prior art, need especially a kind of boiler exhaust gas denitrification apparatus, to solve the deficiencies in the prior art.
The utility model content
Contain a large amount of pollutants for boiler exhaust gas in the prior art, and flow to the pollution that can cause environment in the air, the utility model proposes a kind of boiler exhaust gas denitrification apparatus, simple in structure, can be effectively the pollutant of boiler be carried out filtered and recycled, really to be discharged into extraneous gas be do not endanger the people healthy to treasured, and flow process is simple, space hold is few, and is practical.
To achieve these goals, the technical solution of the utility model is as follows:
A kind of boiler exhaust gas denitrification apparatus, comprise transfer tube, one end of described transfer tube is set to the tail gas import, its other end is set to exhaust port, and the centre of transfer tube is provided with catalytic unit, and the below of described tail gas import is provided with electric cleaner, the below of exhaust port is provided with air-introduced machine, one end of described catalytic unit is equipped with catalyst inlet, and its other end is equipped with compressor, and described compressor one side is equipped with the product stream siphunculus.
End at product stream siphunculus described in the utility model is equipped with the product collection box.
In an embodiment of the present utility model, the top of described air-introduced machine is provided with fan.
Further, described transfer tube be shaped as U-shaped.
The beneficial effects of the utility model are: this product structure is simple, easy to use, can be to carry out improvement and installation in original boiler applications field, in factory that equipment making is complete, the component device shipping is on-the-spot, first the basis is built up at the scene, connect with pipeline, and do not affect in time the original production plan, the tail gas that boiler produces can directly enter into denitrification apparatus, in the denitration assembling device tail gas and Recyclable is separated, having changed in the past, multiple cone equipment is installed separately, investment is large, take up an area a large difficult problem, and removal efficiency is high, and the investment price is relatively low, makes and optimizes, to the environment non-secondary pollution, alleviated production cost, also reduced workman's labour intensity, the automaticity of device is high, outward appearance is unique, satisfy the demand of modernization development, modern design is easy to promote and use.
