Abstract
The utility model discloses a chloride propyl trichlorosilane esterification tail gas absorption device which comprises four-stage transit tanks and four-stage absorption towers communicated with the transit tanks in one-to-one corresponding mode. The four-stage absorption towers are sequentially communicated, and condensers and conveying pumps are respectively connected between each stage of transmit tanks and absorption towers. A third stage conveying pump is connected with a second stage condenser through a pipeline, and a second conveying pump is connected with a first condenser through a pipeline. The chloride propyl trichlorosilane esterification tail gas absorption device can effectively absorb hydrogen chloride tail gas by matching the multistage absorption towers and the transmit tanks, reduces damage to environment by chloride propyl trichlorosilane esterification, and has good social significance.
Description
Technical field
The utility model relates to the device for absorbing tail gas field, is specially a kind of chloropropyl trichloro-silane esterification device for absorbing tail gas.
Background technology
The chloropropyl alkoxy silane by trichlorosilane and chloropropene after addition reaction, generate chloropropyl trichloro-silane, this silane activity is higher, can't directly use in industry, not have coupling effect with inorganic material, this material need pass through through over-churning, obtain the silane coupler of alkoxyl type, alkoxyl generates Si-OH through after being hydrolyzed, and again produces certain coupling effect with inorganic material.In the time of the chloropropyl trichloro-silane esterification, can produce a large amount of accessory substances, hydrogen chloride gas, has stronger corrosivity, most domestic adopts the hydrogen chloride absorption device of discontinuous at present, in absorbing hydrogen chloride, acidity can increase gradually, still, and when concentration of hydrochloric acid is low, the device of employing water absorbing hydrogen chloride is easy to reach the requirement of this respect, if the concentration of hydrochloric acid need to be brought up to more than 30%, be difficult to accomplish for the absorption plant of discontinuous, and the tail gas exit has very large tail gas to shed, environment is caused larger harm, and the lower hydrochloric acid of concentration exists certain limitation aspect recycling simultaneously.
The utility model content
The utility model purpose provides a kind of chlorine trisilalkane trichlorosilane esterification device for absorbing tail gas, to solve the relatively poor problem of hydrogen chloride absorption device absorbing hydrogen chloride assimilation effect of prior art discontinuous.
In order to achieve the above object, the technical scheme that adopts of the utility model is:
Chlorine trisilalkane trichlorosilane esterification device for absorbing tail gas, it is characterized in that: comprise that level Four is contained with respectively the transfer tank of hydrochloric acid, and respectively with the transfer tank level Four absorption tower of corresponding connection one by one, the level Four absorption tower is communicated with successively, wherein first order absorption tower is connected with the appendix of input tail gas, be contained with liquid caustic soda and fourth stage absorption tower in the fourth stage absorption tower and be connected with the blast pipe that discharge tail gas is absorbed rear gas, be connected with respectively condenser between every grade of transfer tank and each the self-corresponding absorption tower, delivery pump, wherein the input port of third level transfer tank has access to the water inlet pipe of input pure water, third level delivery pump is by pipeline access second level condenser, second level delivery pump is connected with drainpipe by pipeline access first order condenser on the first order delivery pump delivery outlet.
Described chlorine trisilalkane trichlorosilane esterification device for absorbing tail gas is characterized in that: have access to delivery pump on the appendix that first order absorption tower connects.
The utility model cooperates the transfer tank effectively to absorb hydrogen chloride tail gas by the multistage absorption tower, has reduced chloropropyl trichloro-silane esterification environmental disruption, has well good social effect.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
As shown in Figure 1.Chlorine trisilalkane trichlorosilane esterification device for absorbing tail gas, comprise that level Four is contained with respectively the transfer tank V1-V4 of hydrochloric acid, and respectively with the transfer tank level Four absorption tower T1-T4 of corresponding connection one by one, level Four absorption tower T1-T4 is communicated with successively, wherein first order absorption tower T1 is connected with the appendix of input tail gas, be contained with liquid caustic soda and fourth stage absorption tower T4 among the T4 of fourth stage absorption tower and be connected with the blast pipe that discharge tail gas is absorbed rear gas, be connected with condenser F1 between first order transfer tank V1 and the first order absorption tower T1, delivery pump P1, be connected with condenser F2 between second level transfer tank V2 and the first order absorption tower T2, delivery pump P2, be connected with condenser F3 between third level transfer tank V3 and the first order absorption tower T3, delivery pump P3, be connected with condenser F4 between fourth stage transfer tank V4 and the first order absorption tower T4, delivery pump P4, wherein the input port of third level transfer tank V3 has access to the water inlet pipe of input pure water, third level delivery pump P3 is by pipeline access second level condenser F2, second level delivery pump P2 is connected with drainpipe by pipeline access first order condenser F1 on the first order delivery pump P1 delivery outlet.Have access to delivery pump P5 on the appendix that first order absorption tower T1 connects.
When hydrochloric acid produces from reaction unit, by first order absorption tower, unabsorbed hydrogen chloride enters absorption tower, the second level simultaneously, remaining hydrogen chloride is again by the third level and fourth stage absorption tower, during finally to fourth stage absorption tower, adopt absorbing by liquid caustic soda, can guarantee final emptying place, emit without hydrogen chloride gas.Simultaneously, process water adds in third level transfer tank first, liquid after the absorption, again by third level transfer tank to second level transfer tank, again by second level transfer tank to first order transfer tank, in first order transfer tank, adopt the higher hydrochloric acid liquid of concentration to absorb the hydrogen chloride gas of high concentration, arrive more than 30% with the hydrogen cloride concentration that guarantees to contain in the hydrochloric acid liquid, the hydrochloric acid solution after again will absorbing is transferred to hydrochloric acid tank.Complete equipment does not exist concentration of hydrochloric acid not reach the phenomenon of requirement, and the final tail gas phenomenon that do not have hydrogen chloride to emit, and complete equipment has satisfied the requirement of above two aspects, has larger advance in the absorption plant of hydrogen chloride.
Esterification tail gas process delivery pump P5 enters absorption tower T1, T2 successively, T3, T4 absorb, the concentration V1 of the hydrochloric acid in the transfer tank＞V2＞V3＞V4, pure water begins to add from transfer tank V3, then step by step to transfer tank V2, V1 transfer, finally by the absorption of maximum concentration among the transfer tank V1, squeeze into again hydrochloric acid tank, in every grade absorption process, be exothermic phenomenon, therefore, add condenser system every grade of absorption, to guarantee maximum degree of absorption.Add liquid caustic soda among the T4 of fourth stage absorption tower, absorb fully to guarantee final tail gas, increase simultaneously condensing unit.
