Description

A kind of regenerative system for flue gas desulfurization device line

Technical field

The application is related to environmental protection industry (epi) technical field of atmospheric pollution control, and in particular to one kind is used for flue gas desulfurization device line Regenerative system.

Background technology

Other are major pollutants in air to sulfur dioxide, there is very big harm to link and health, while It is the main reason for producing acid rain.With rapid development of economy, the discharge capacity of China's sulfur dioxide has occupied first place in the world, All there is acid rain to some extent in various regions, turn into the acid rain seriously polluted area after Europe, North America.Therefore, industrial discharge flue gas In, the removing improvement of sulfur dioxide is the important topic in Environmental Protection in China field.

Administered for the sulfur dioxide removal of industrial smoke, usual mode is using desulphurization plant line in industrial smoke Sulfur dioxide is handled, and current desulphurization plant line mainly includes gas supply assembly and desulfurization module, in real work, is supplied Industrial smoke is sent into desulfurization module by pneumatic module, and desulfurization module is usually desulfurizing tower, and desulfurizing tower takes off the sulfur dioxide in flue gas Remove, so realize the control to flue gas.

Adopt in manner just described, not only can significantly reduce the content of sulfur dioxide in industrial smoke, reduce industrial cigarette Pollution of the gas to environment, meanwhile, in the case of conditional, the sulfur dioxide of removing can also be collected and sharp again With.

With going deep into for research, inventor has found that above-mentioned desulphurization plant line still also there are deficiency, and concrete reason exists In：

In current Structure of Flue Gas Desulfuration Absorbing, desulfurization method is usually dry desulfurization or wet desulphurization, is carrying out desulfurization work When making, industrial smoke is by entering in tower body below tower body, and corresponding desulfurization agent, and then realizes the removing of sulfur dioxide, However, it is found by the inventors that in current desulfurization method, flue gas is not high with desulfurization agent efficiency, causes the use of desulfurizing agent And it is insufficient, the waste of desulfurizing agent is caused, the problem of also easily causing the removal efficiency of sulfur dioxide in flue gas low.

The content of the invention

The purpose of the application is：For sulfur dioxide removal rate in current desulphurization plant line it is not high the problem of, there is provided one Kind can improve the desulphurization plant of sulfur dioxide removal rate.

In order to realize foregoing invention purpose, this application provides following technical scheme：

A kind of filtering layer component for desulfurizing tower, the filtering layer component be located at desulfurizing tower gas approach and exhanst gas outlet it Between, after flue gas is first passed through the filtering layer component, then to be discharged by the exhanst gas outlet, the filtering layer component includes filter layer, Some exhaust gases passes passed through for flue gas are there are in the filter layer.

The filtering layer component of the application, there is some passages passed through for flue gas in filter layer, and the flue gas into tower body passes through These passages are discharged by exhanst gas outlet again, are adopted in such a way, can greatly improve sulfur dioxide in flue gas and desulfurizing agent Contacting efficiency, and then improve the removal efficiency of sulfur dioxide in flue gas, the desulfurizing agent in the application can be can and sulfur dioxide Occur to chemically react and then realize the chemicals of sulfur dioxide removal or for being catalyzed sulfur dioxide and other materials Occur to chemically react and then realize the catalyst of sulfur dioxide removal.

Preferably, the filter layer by some granular filter elements the shape in a manner of accumulating or lay Into formed with gap between adjacent filtration member, to be connected with each other either independently of each other or part connects between each gap Mode form some exhaust gases passes passed through for flue gas.

In this scenario, the exhaust gases passes passed through for flue gas are formed using aforesaid way, these exhaust gases passes shapes are random Property high, or bending or tortuous, be flue gas by providing longer path, can further improve connecing for flue gas and desulfurizing agent Touch efficiency, and then the further removal efficiency for improving sulfur dioxide.

Preferably, the filter element is spherical, ellipsoid or column.

Using the filter element of above-mentioned shape and specification, in accumulation or laying, facilitate the formation of exhaust gases passes, and The exhaust gases passes formed also have more suitably sized, that is, ensure that flue gas and desulfurizing agent have higher contacting efficiency, together When have and avoid the formation of excessive resistance, facilitate passing through for flue gas.

It is further preferred that the filter element is cylindric, a diameter of 3-10mm.

It is further preferred that the filter element is cylindric, a diameter of 4-6mm.

In actual design and in use, inventor's discovery, is arranged to above-mentioned size by filter element, makes its each filter element Between form size suitable gap, while ensureing that flue gas circulation is smooth, it is ensured that the gap inside filter layer has foot Enough big areas, ensure the removal efficiency of sulfur dioxide.
