Description

Combined dust collector

technical field

The utility model relates to an environmental protection device, in particular to a combined dust collector.

Background technique

China is the world's largest producer and consumer of coal. It emits 24 million tons of SO ₂ and 7 million tons of NO ₂ into the atmosphere every year, as well as a large amount of smoke and dust. A large amount of SO ₂ and NO ₂ pollution and the resulting acid precipitation Pollution has caused serious harm to human health, agriculture, forests, fisheries, materials, etc.

Boiler smoke and dust eliminators in my country all belong to dry type, wet type vortex dust collector and electrostatic precipitator. Their dust removal efficiency cannot meet the boiler smoke and dust emission standards, and the atmospheric environment is polluted, especially the removal of sulfur dioxide and nitrogen oxides in boiler flue gas. The rate is not high, and the pollution to the atmospheric environment is very harmful to the health of the human body. For this reason, the country has invested a huge amount of manpower and financial resources, but it still cannot be effectively treated; it has spent huge sums of money to introduce many sets of large-scale power plant flue gas treatment technologies from abroad, but all because of the huge investment in the equipment, high operating costs, and large footprint. For major reasons, it cannot be popularized and used. Especially for small and medium-sized boiler users, because there is no economical and practical flue gas treatment process and equipment, they are forced to use natural gas or oil boilers with expensive fuel.

In order to solve the problem that the existing boiler smoke and dust removal efficiency cannot meet the environmental protection emission standards, it is very important to remove sulfur dioxide and nitrogen oxides in the boiler smoke and reduce the pollution to the atmospheric environment.

Utility model content

The purpose of this utility model is to provide a combined dust collector for the above-mentioned deficiencies in the prior art.

The above-mentioned technical problems of the utility model are mainly solved by the following technical solutions:

A combined dust collector, comprising an injection system, a dust removal chamber and an ash hopper, characterized in that the injection system is arranged above the dust removal chamber, and the ash hopper is located below the dust removal chamber; the injection system and The dust chambers are tightly connected by bolts and can be disassembled separately.

Further, the blowing system includes a blowing chamber, a fan, an air outlet, a blowing pipe, an air bag and a pulse valve, and the blowing pipe is located in the blowing chamber.

Further, the blowing pipe corresponds to the filter below, and the filter is located in the dust removal chamber, and the dust removal chamber communicates with the blowing chamber through the upper port of the filter.

Further, the dust removal chamber also has an air inlet.

Preferably, the filter is a filter bag or a filter cartridge.

It can be seen from the above technical scheme that the utility model has the technical effects of small size, convenient installation, large filter material area, strong processing capacity, high dust removal efficiency and convenient dust removal.

Description of drawings

Fig. 1 is a structural schematic diagram of an embodiment of the utility model.

Detailed ways

Below in conjunction with embodiment and accompanying drawing, the technical solution of the utility model is described further in detail.

A combined dust collector includes an injection system 1 , a dust removal chamber 2 and an ash hopper 3 , the injection system 1 is arranged above the dust removal chamber 2 , and the ash hopper 11 is located below the dust removal chamber 2 .

The blowing system 1 includes a blowing chamber 8 , a fan 2 , an air outlet 3 , a blowing pipe 4 , an air bag 6 and a pulse valve 5 , and the blowing pipe 4 is located in the blowing chamber 8 .

The dust removal chamber 2 includes a filter 10 and an air inlet 7, and a baffle 9 for drainage can also be provided. The top of the filter 10 corresponds to the spray pipe 4 . The dust removal chamber 2 communicates with the blowing chamber 8 only through the upper opening of the filter 10 in space.

The blowing system 1 is tightly connected in the form of bolts between the blowing chamber 8 and the dust removal chamber 2, and can be disassembled and installed separately.

The ash hopper 11 is a drawer-shaped ash hopper, which can be directly pulled out and separated from the dust removal chamber 2 .

The filter 10 is a filter bag or a filter cartridge.

The embodiment of a combined dust collector provided by the utility model has been introduced in detail above. For those of ordinary skill in the art, according to the idea of the utility model embodiment, there will be changes in the specific implementation and application range Things, such as the shape of the box and the connection method of the filter, can be changed according to actual needs. To sum up, the contents of this specification should not be understood as limiting the utility model.
