Abstract
The utility model discloses a tail gas exhaust device in chlorohydrination process, which comprises a tail gas inlet and an exhaust outlet communicated with the atmosphere. Since a gas-liquid separator is arranged between the tail gas inlet and the exhaust outlet, tail gas can be buffered in the gas-liquid separator to be subjected to physical separation of gas and liquid phases, acid liquid in the tail gas can be recovered, liquid phase entrained in exhaust gas can be eliminated, corrosion of exhausted gas to the surrounding environment can be reduced, and field environments can be improved.
Description
Technical field
The utility model relates to a kind of tail gas emptying device, relates in particular to the tail gas emptying device in a kind of chlorohydrination operation.
Background technology
The reaction system of chlorohydrination operation was the propylene reaction; Also a large amount of nitrogen to be charged into for guaranteeing that system's oxygen content is qualified, therefore, a large amount of reaction end gas can be produced in the system; Part tail gas recycles, and part tail gas needs the oxygen of emptying in order to balance sysmte pressure and removal system accumulated.The emptying device operated by rotary motion is in the 6th buildings, and blow-down pipe is directly connected atmosphere, because of tail gas contains part steam and acid; In the emptying end gas; Entrained liquid is serious, is prone to coagulate at the drain place to be dropped in field ground or liquid phase along blow-down pipe drippage ground, corroded pipeline, equipment and ground; On-the-spot acidic smell is big, has a strong impact on environment.
The utility model content
The utility model purpose: the purpose of the utility model is the deficiency to prior art, provide a kind of can be with the tail gas emptying device in the chlorohydrination operation of moisture in the tail gas and acid Separation and Recovery.
Technical scheme: the tail gas emptying device in the described chlorohydrination operation of the utility model; Comprise the tail gas import and with the drain of atmosphere; Be provided with gas-liquid separator between said tail gas import and the said drain, through adding gas-liquid separation device with moisture content in the emptying end gas and acid Separation and Recovery.
In order to recycle the recover materials in the gas-liquid separation device, the lower end of said gas-liquid separator is provided with the lime set outlet that links to each other with recycling can.
The utility model compared with prior art; Its beneficial effect is: 1, the utility model cushions tail gas through between tail gas import and drain, being provided with gas-liquid separator therein, carries out the physical separation of gas-liquid phase; And recovery acidic liquid wherein; Reach the liquid phase of eliminating in the emptying gas and carry secretly, reduce the corrosion of emptying gas, improve the purpose of site environment surrounding enviroment; 2, the utility model apparatus structure is simple, and is easy to process, and financial cost is low, and what reach is effective.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model technical scheme is elaborated, but the protection domain of the utility model is not limited to said embodiment.
Embodiment: as shown in Figure 1, the tail gas emptying device in the said chlorohydrination operation of the utility model, comprise tail gas import 1 and with the drain 2 of atmosphere, be provided with gas-liquid separator 3 between said tail gas import 1 and the said drain 2; The lower end of said gas-liquid separator 3 is provided with the lime set outlet 5 that links to each other with recycling can 4.
Treat the advanced gas-liquid separator of tail gas of emptying, carry out gas-liquid separation after, emptying again.After the use, the liquid phase of dropping a hint is carried elimination secretly, on-the-spot no lime set drippage, and enhancement of environment is obvious.
As stated, although represented and explained the utility model that with reference to specific preferred embodiment it shall not be construed as the restriction to the utility model self.Under the spirit and scope prerequisite of the utility model that does not break away from the accompanying claims definition, can make various variations in form with on the details to it.
Claims (2)
1. the tail gas emptying device in the chlorohydrination operation, comprise the tail gas import and with the drain of atmosphere, it is characterized in that: be provided with gas-liquid separator between said tail gas import and the said drain.
2. the tail gas emptying device in the chlorohydrination operation according to claim 1 is characterized in that: the lower end of said gas-liquid separator is provided with the lime set outlet that links to each other with recycling can.
