The chemical tail gas absorption apparatus disclosed by the utility model has the advantages that the spraying chamber is arranged so as to cool the tail gas to room temperature, firstly the tail gas which reacts with water or can be absorbed by water is purified so as to complete primary purification; then the absorption chambers are arranged, oxidizing agents or halogens are arranged in the absorption chambers and serve as absorbents so as to absorb the residual tail gas, the multiple absorption chambers are used for multiple purification, and the chemical tail gas absorption apparatus is simple to operate and high in purification degree and meets the high-efficiency, green and environmental-protection subject requirements of modern society.
Description
Technical field
The utility model relates to a kind of vapour deposition process and absorbs tail gas unit.
Background technology
Chemical vapour deposition (CVD) (Chemicalvapordeposition is called for short CVD) is that reactive material issues biochemical reaction in gaseous state condition, generates solid matter and is deposited on the solid matrix surface of heating, and then make the technology of solid material.It belongs to the gaseous state mass transport process of former subcategory in essence.On the other side is physical vapor deposition (PVD).Chemical vapour deposition (CVD) is a kind of method of vapor-phase growing of preparing material, it is that compound, elementary gas that one or more are contained to formation film element pass into the reative cell that is placed with base material, deposits the technology of solid film by space gas-phase chemical reaction on matrix surface.
Modern science and Technology Need use the New Inorganic Materials of a large amount of Various Functions, and these functional materials must be high-purity, or the dopant material that some kinds impurity forms wittingly in high-purity material.But many preparation methods that we are familiar with in the past, as precipitation and crystallization etc. in high melt, the aqueous solution are often difficult to meet these requirements, are also difficult to guarantee to obtain highly purified product.Therefore, the synthetic major subjects just becoming in modern material science of New Inorganic Materials.Chemical vapor deposition is the new technology of the preparation inorganic material that grows up nearly decades.CVD method has been widely used in purifying substances, has developed new crystal, the various monocrystalline of deposit, polycrystalline or glassy state inorganic thin film material.These materials can be oxide, sulfide, nitride, carbide, can be also compound between binary in III-V, II-IV, IV-VI family or polynary element, and their physical function can accurately be controlled by the deposition process of gas phase doping.At present, chemical vapor deposition has become a frontier of inorganic synthetic chemistry.
In chemical vapor deposition method tail gas, contain multiple poisonous fume, such as polyfluoride, arsine, phosphine, borine, silane etc., if be directly discharged in atmosphere, can cause severe contamination to environment, therefore these toxic gases must just can enter in atmosphere after strict processing reaches discharge standard.Wherein some waste gas can react with water, some other composition can be absorbed by water, therefore, the U.S., Japan and other countries adopt water to absorb exhaust gas processing device mostly at present, but wherein also have some not react and can not can be directly discharged in air by absorbed gas with water, cause the destruction to environment.Therefore, working out a kind of device for absorbing tail gas is efficiently significant.
Because the defect that above-mentioned existing chemical tail gas absorption apparatus exists, the design people, actively research and innovation in addition, to founding a kind of chemical tail gas absorption apparatus of new structure, makes it have more practicality.
Utility model content
Main purpose of the present utility model is, overcomes the defect that existing chemical tail gas absorption apparatus exists, and a kind of chemical tail gas absorption apparatus of new structure is provided, and improves tail gas clean-up degree, thereby is more suitable for practicality, and have the value in industry.
The purpose of this utility model and solve its technical problem and realize by the following technical solutions.According to the one chemistry tail gas absorption apparatus the utility model proposes, described absorption apparatus includes a housing, described case top one side is provided with air inlet and is provided with exhaust outlet at bottom opposite side, in described housing, be provided with from right to left connected successively spray chamber, the first absorption chamber, the second absorption chamber and the 3rd absorption chamber, described spray chamber is connected with described air inlet, and described exhaust outlet is connected with described the 3rd absorption chamber.
As preferably, aforesaid chemical tail gas absorption apparatus, fills oxidant absorbent in described the first absorption chamber.
As preferably, aforesaid chemical tail gas absorption apparatus, described oxidant absorbent is potassium permanganate.
As preferably, aforesaid chemical tail gas absorption apparatus, fills halogen absorbent in described the second absorption chamber.
By technique scheme, chemical tail gas absorption apparatus of the present utility model at least has following advantages:
Chemical tail gas absorption apparatus of the present utility model, is provided with spray chamber, and exhaust temperature is dropped to room temperature, first purges the tail gas that reacts or can be absorbed by water with water, completes preliminary purification; Absorption chamber is then set, oxidant or halogen is set in absorption chamber and sponges remaining tail gas as absorbent, multiple absorption chambers are set, multiple purifying, simple to operate, degree of purification is high, meets that modern society is efficient, green, the subject requirement of environmental protection.
Above-mentioned explanation is only the general introduction of technical solutions of the utility model, in order to better understand technological means of the present utility model, and can be implemented according to the content of description, below with preferred embodiment of the present utility model and coordinate accompanying drawing to be described in detail as follows.
