Description
Technical field
The utility model relates to the device for absorbing tail gas of a kind of chlorine hydride tail gas absorber, particularly a kind of γ-r-chloropropyl trimethoxyl silane.
Background technology
γ-chloropropyl triethoxysilane is not only a kind of useful silane coupler, or a kind of broad-spectrum intermediate, can be used for the synthetic of plurality of silane coupling agents.By the application study of γ-chloropropyl triethoxysilane at rubber, found that γ-chloropropyl triethoxysilane all has good effect in single rubber and mixed rubber, can obviously improve processing characteristics and some physical properties of rubber.When γ-chloropropyl triethoxysilane replaces Si 69 and uses, rubber performance to improve effect almost consistent, significantly reduced the production cost of rubber.As a kind of rubber processing aids, be used for processing the inorganic filler in the various halo rubber of coupling, such as neoprene, chlorinated scoline, chlorohydrin rubber, chlorosulfonated polyethylene etc., to improve various physical and mechanical properties.This product also is the base stock of synthetic multiple important organo-silicon coupling agent Si-69, Si-75, KH-550, gamma-aminopropyl-triethoxy-silane, N-β-aminoethyl-γ-chloropropyl triethoxysilane etc.Si-69, Si-75 are radial and high-grade rubber special assistant, in order to improve wear-resisting, the tear-resistant intensity of tire and other rubber.KH-550 is widely used in the industries such as glass, casting, yarn fabric auxiliary agent, insulating materials, adhesive.γ-chloropropyl triethoxysilane also can be used for the synthetic organo-silicon compound that contain quaternary ammonium salt cationic in addition, as mould proof, deodorization finishing agent, has special sterilization, deodorization, antistatic and surface-active.
The tail gas that produces in γ-chloropropyl triethoxysilane production is hydrogen chloride gas, present processing mainly is the method that absorbs by water, but absorption process is had nothing in common with each other, mainly be by using circulating pump to absorb in the entry of hydrogen chloride gas band, for example using jet pump to produce the negative pressure extracting hydrogen chloride gas absorbs, utilize the circulating pump circulation to absorb, so that form the concentration that hydrochloric acid reaches take-away.Only have 50% but absorptivity is low like this, also have a large amount of hydrogen chloride gas along with evacuated tube enters in the air, affect environment.
The utility model content
Its purpose of the utility model just is to provide a kind of chlorine hydride tail gas absorber, has that absorptivity is high, the characteristics of environmental protection, and increases economic benefit.
The technical scheme that realizes above-mentioned purpose and take, comprise circulating pump and vacuum unit and tank, condensator outlet connects falling-film absorber, falling-film absorber exports an end and connects 1# pans one end bonding pad absorption tower, described 1# pans one bring out mouth and connect falling-film absorber through circulating pump, described packed absorber exports an end and connects the 2# pans, and the other end connects vacuum unit and tank, and described 2# pans one bring out mouth through circulating pump bonding pad absorption tower.
Compared with prior art the utlity model has following advantage.
Because the structural design that has adopted B-grade condensation and vacuum falling film to absorb, carry out the absorption of hydrogen chloride gas, absorptivity can reach 99%-100%, stop hydrogen chloride gas and entered the air impact environment, effectively utilizing hydrogen chloride gas to make hydrochloric acid increases economic benefit, reduces the cost of γ-chloropropyl triethoxysilane.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Accompanying drawing is this apparatus structure principle schematic.
Among the figure: the 1-condenser; The 2-condenser; The 3-falling-film absorber; The 4-1# pans; The 5-circulating pump; The 6-packed absorber; The 7-2# pans; The 8-circulating pump; The 9-vacuum tank; 10-vacuum unit and tank.
The specific embodiment
This device comprises circulating pump and vacuum unit and tank, as shown in drawings, condensator outlet connects falling-film absorber 3, falling-film absorber 3 outlets one end connects 1# pans 4 one end bonding pad absorption towers 6, described 1# pans 4 one bring out mouth and connect falling-film absorbers 3 through circulating pump 5, described packed absorber 6 outlets one end connects 2# pans 7, and the other end connects vacuum unit and tank 10, and described 2# pans 7 one bring out mouth through circulating pump 8 bonding pad absorption towers 6.
Described condenser comprises 1# condenser 1 and 2 series connection of 2# condenser.
Described vacuum unit and tank 10 front ends are provided with vacuum tank 9.
Reaction produces hydrogen chloride gas in embodiment (1) γ-chloropropyl triethoxysilane esterification device, and the ethanol of hydrogen chloride gas being carried secretly by one-level water-cooled condenser 1 and secondary cryogenic condenser 2 etc. is condensed into liquid and enters esterification device;
(2) hydrogen chloride gas is along with the negative pressure of vacuum system enters falling-film absorber 3, water in the 1# pans 4 also enters falling-film absorber 3 by circulating pump 5, hydrogen chloride is absorbed by water, enter pans, utilize circulating pump 5 to make the continuous absorbing hydrogen chloride gas of water in the 1# pans 4, to reach the hydrochloric acid of concentration;
(3) hydrogen chloride gas that does not absorb fully in the falling-film absorber 3, enter packed absorber 6, circulating pump 8 by 2# pans 7 enters packed absorber 6 tops with the water in the 2# pans 7 and sprays, making the hydrogen chloride gas that upwards flows be sprayed downward water absorbs at filler, enter 2# pans 7, utilize circulating pump 8 to make the continuous absorbing hydrogen chloride gas of water in the 2# pans 7, to reach the hydrochloric acid of concentration;
(4) packed absorber 6 does not absorb completely that hydrogen chloride gas is inhaled into the tank 10 of vacuum system along with vacuum system, to such an extent as to the absorptivity of hydrogen chloride gas reaches 99%-100%;
(5) concentration of hydrochloric acid that makes of above hydrogen chloride gas absorption plant can reach 33%-35%, and temperature is low, do not need cooling, control is convenient, stable operation, the hydrochloric acid of the concentration hydrochloric acid that enters my company takes off and analyses the workshop and will make high-purity chlorination hydrogen and try out as the raw material in trichlorosilane workshop like this.
Characteristics:
1. this device passes through the absorption tube that B-grade condensation afterchlorinate hydrogen enters falling-film absorber, absorbs, and absorption tube uses cooling water that absorption tube is carried out cold treatment outward, the water that has absorbed hydrogen chloride gas is cooled off, make the temperature of hydrochloric acid lower, do not need to carry out again cooling processing;
2. falling-film absorber does not absorb completely that gas enters packed absorber, packed absorber has used suitable fillers, makes the water of spray larger with the area that hydrogen chloride gas contacts in filler, absorbs more complete, through after the packed absorber, there is not absorbed hydrogen chloride gas seldom;
3. through not having absorbed hydrogen chloride gas to enter the tank of vacuum system behind falling-film absorber and the packed absorber, again absorbed by water, guaranteed so the fully absorption of hydrogen chloride gas, so absorptivity can reach 99%-100%.
