The gas and liquid separator comprises a gas and liquid separation tank (5) arranged on the top of an esterification working process reaction kettle, and is characterized in that the top of the gas and liquid separation tank (5) is connected with a gas and liquid feeding pipe (1) through a first ball valve (2), and the bottom of the gas and liquid separation tank (5) is connected with an alcohol discharging pipe (6) through a second ball valve (7); the alcohol discharging pipe (6) is connected to the top of the esterification working process reaction kettle through a condensed fluid return pipe; and one side of the upper part of the gas and liquid separation tank (5) is connected with a tail gas absorption device through a hydrochloric acid gas discharging pipe (4). The gas and liquid separator for esterification has the advantages of running safely and steadily, effectively improving the running quality and the running efficiency of a system, reducing the environment pollution and the like along with a simple structure.
Description
Technical field
Gas-liquid separator is used in esterification, belongs to chemical industry esterification apparatus field, is specifically related to a kind of separator that removes hydrochloric acid gas in esterification workshop section.
Background technology
Existing esterification technique; Like the esterification of silester, be at first to pump into into the raw material silicon tetrachloride with constant displacement pump from the agitated reactor cat head, add ethanol vaporization liquid and inertia light component from tower joint 1/3rd then; And keep certain still temperature; Make its fully reaction in packed tower, subsequently, the silester esterifying liquid is continuous extraction at the bottom of tower; Be provided with offgas duct and condensate liquid return duct at cat head, under the vacuum hydrogen chloride gas removed the aspiration receiving apparatus that truncates then and absorb collection, not reacted alcohol then is condensed and is back to Ta Jienei and carries out recycle.
But this treating apparatus; As easy as rolling off a log when esterification workshop section vacuum removal hydrochloric acid gas, form the entrained liquid of acid alcohol, so not only reduced the running quality and the operational efficiency of whole system; And increased operating cost; When operation, also have other many potential safety hazards, shortened the service life of equipment, also brought a large amount of pollutions to environment.
Summary of the invention
The technical problem that the utility model will solve is: overcome the deficiency of prior art, provide a kind of to gas-liquid separate back individual processing, safety and steady, gas-liquid separator is used in esterification with low cost.
The utility model solves the technical scheme that its technical problem adopted: gas-liquid separator is used in this esterification; Comprise the knockout drum that is installed in esterification workshop section agitated reactor cat head; It is characterized in that: the gas-liquid separation tank top connects the gas-liquid feed pipe through first ball valve; The bottom connects pure discharge nozzle through second ball valve, and pure discharge nozzle connects esterification workshop section agitated reactor cat head through the condensate liquid return duct, and knockout drum top one side connects device for absorbing tail gas through hydrochloric acid gas discharge nozzle.At first gas-liquid mixture is carried out gas-liquid separation completely, hydrochloric acid gas and alcohol after will separating are then collected respectively and are handled.
Described gas-liquid separation tank top one side also is provided with pressure vacuum gauge.Be used for monitoring in real time the pressure condition in the knockout drum, guarantee that device security moves stably.
Compared with prior art, the beneficial effect that is had of the utility model is:
1, simple in structure, reduce cost: at first gas-liquid mixture is carried out gas-liquid separation completely; Hydrochloric acid gas and alcohol after will separating are then collected respectively and are handled, and have solved the problem of the acid alcohol entrained liquid when the vacuum removal hydrogen chloride gas, have improved the running quality and the operational efficiency of whole system; Pure liquid after reclaiming is carried out cycling and reutilization; Not only reduced pollution, and reduced the operating cost of equipment, improved economic benefit environment.
2, safe and reliable, operate steadily: with handling respectively after gas and the fluid separation applications, and monitor in real time, both improved the service life of equipment, guaranteed that also device security moves stably through pressure vacuum gauge.
Description of drawings
Fig. 1 is the utility model structural front view sketch map.
Wherein: 1, gas-liquid feed pipe 2, first ball valve 3, pressure vacuum gauge 4, hydrochloric acid gas discharge nozzle 5, knockout drum 6, pure discharge nozzle 7, second ball valve.
Fig. 1 is the most preferred embodiment of the utility model, further specifies below in conjunction with 1 pair of the utility model of accompanying drawing:
The specific embodiment
With reference to accompanying drawing 1:
Gas-liquid separator is used in this esterification, comprises gas-liquid feed pipe 1, first ball valve 2, pressure vacuum gauge 3, hydrochloric acid gas discharge nozzle 4, the knockout drum 5 that is installed in esterification workshop section agitated reactor cat head, pure discharge nozzle 6 and second ball valve 7.Knockout drum 5 is installed in esterification workshop section agitated reactor cat head; The top connects gas-liquid feed pipe 1 through first ball valve 2; The bottom connects pure discharge nozzle 6 through second ball valve 7, and pure discharge nozzle 6 connects esterification workshop section agitated reactor cat head through the condensate liquid return duct, and knockout drum 5 tops one side is provided with hydrochloric acid gas discharge nozzle 4; Connect device for absorbing tail gas through hydrochloric acid gas discharge nozzle 4, knockout drum 5 tops one side also is provided with pressure vacuum gauge 3.
The course of work is following:
The utility model is when work; The hydrogen chloride gas and the pure mixtures of liquids of discharging from esterification workshop section agitated reactor cat head get into the knockout drum 5 through first ball valve 2 from gas-liquid feed pipe 1; In knockout drum 5, carry out gas-liquid separation; Isolated hydrogen chloride gas is discharged through the hydrochloric acid gas discharge nozzle 4 that knockout drum 5 tops one side is provided with, and gets into then to carry out the centralized collection processing in the device for absorbing tail gas; Isolated pure liquid is then discharged from the pure discharge nozzle 6 of knockout drum 5 bottoms, after the condensation, flows back to the agitated reactor Ta Jienei of esterification workshop section through the condensate liquid return duct, carries out follow-up recycle.
At knockout drum 5 duration of works, the pressure size in pressure vacuum gauge 3 monitoring in real time that can be in real time be provided with through its top jar is carried out suitable adjusting according to the needs of real reaction, guarantees that further device security moves stably.
The above; It only is the preferred embodiment of the utility model; Be not to be the restriction of the utility model being made other form, any professional and technical personnel of being familiar with possibly utilize the technology contents of above-mentioned announcement to change or be modified as the equivalent embodiment of equivalent variations.But every the utility model technical scheme content that do not break away to any simple modification, equivalent variations and remodeling that above embodiment did, still belongs to the protection domain of the utility model technical scheme according to the technical spirit of the utility model.
