Abstract
The utility model discloses a vacuum condensation tail gas recovery system, including vacuum pump, filter, recovery jar and double-pipe heat exchanger, install the check valve on the vacuum pump, the discharge end of vacuum pump passes through gas piping intercommunication double-pipe heat exchanger's feed end, and the intercommunication has the filter on the gas piping, and the discharge end of filter communicates the import of retrieving the jar, and double-pipe heat exchanger's discharge end also communicates the feed end of filter, and is equipped with simultaneously the high point gas vent. The utility model discloses vacuum condensation tail gas recovery system can be with the organic gas in the tail gas through vacuum pump compression condensation to and the double-pipe heat exchanger condensation, the material that the condensation got off, through the filter, enters into the recovery jar after detaching impurity, recycle, and the trace organic gas after the condensation discharges up to standard with noncondensable gas, reduces organic gas emission environmental pollution.
Description
Technical Field
The utility model relates to a chemical industry field specifically is a vacuum condensation tail gas recovery system.
Background
A small amount of organic gas is generated in the chemical production process, the small amount of organic gas is directly discharged and does not reach the standard after passing through the outlet of the vacuum pump, or the organic gas needs to be adsorbed by activated carbon, so that the problem of solid waste is caused, and meanwhile, the consumption of raw materials is increased due to the continuously discharged gas.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a vacuum condensation tail gas recovery system to solve the problem that proposes among the above-mentioned background art.
In order to solve the technical problem, the utility model provides a following technical scheme: the utility model provides a vacuum condensation tail gas recovery system, includes vacuum pump, filter, recovery jar and double-pipe heat exchanger, install the check valve on the vacuum pump, the discharge end of vacuum pump passes through the gas pipeline intercommunication double-pipe heat exchanger's feed end, the last intercommunication of gas pipeline has the filter, the discharge end intercommunication of filter the import of recovery jar, double-pipe heat exchanger's discharge end also communicates the feed end of filter, and be equipped with simultaneously the high point gas vent.
And a liquid level meter is arranged on the recovery tank.
Compared with the prior art, the utility model discloses the beneficial effect who reaches is: the utility model discloses vacuum condensation tail gas recovery system can be with the organic gas in the tail gas through vacuum pump compression condensation to and the double-pipe heat exchanger condensation, the material that the condensation got off, through the filter, enters into the recovery jar after detaching impurity, recycle, and trace organic gas after the condensation and noncondensable gas discharge to reach standard reduce organic gas and discharge environmental pollution, and tail gas recovery has also further reduced raw materials consumption simultaneously.
Drawings
The accompanying drawings are included to provide a further understanding of the invention, and are incorporated in and constitute a part of this specification. In the drawings:
FIG. 1 is a flow chart of the vacuum condensation tail gas recovery system of the present invention;
in the figure: 1, a check valve; 2, a vacuum pump; 3, a filter; 4, a recovery tank; 5, a liquid level meter; 6 double-pipe heat exchanger; 7 high point exhaust port; 8 gas pipeline.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1, the present invention provides a technical solution: the utility model provides a vacuum condensation tail gas recovery system, includes vacuum pump 2, filter 3, retrieves jar 4 and double-pipe heat exchanger 6, installs check valve 1 on vacuum pump 2, and the discharge end of vacuum pump 2 passes through the feed end of 8 intercommunication double-pipe heat exchangers 6 of gas pipeline, and the intercommunication has filter 3 on the gas pipeline 8, and the discharge end intercommunication of filter 3 retrieves jar 4's import, and the discharge end of double-pipe heat exchanger 6 also communicates filter 3's feed end, and is equipped with high point gas vent 7 simultaneously.
The recovery tank 4 is provided with a liquid level meter 5.
The utility model discloses a theory of operation:
mixed tail gas gets into vacuum pump 2 through check valve 1, mixed tail gas contains a small amount of organic gas and noncondensable gas (the principal ingredients is air, nitrogen gas), export through vacuum pump 2, become the ordinary pressure by the vacuum, most organic gas in the tail gas will liquefy at the vacuum outlet, get into recovery jar 4 through gas pipeline 8 through filter 3, a small amount of organic gas gets into double pipe heat exchanger 6 through gas pipeline 8, double pipe heat exchanger 6 leads to the cooling water, continue to be condensed below 40 ℃, the material that condenses, get into recovery jar 4 through pipeline process filter 3 in, and remaining trace organic gas and noncondensable gas, it discharges to advance the high point gas vent.
It is noted that relational terms such as first and second, and the like may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Also, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus.
Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described in the foregoing embodiments, or equivalents may be substituted for elements thereof. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
