The utility model discloses make the medium that flows back in the gas-liquid separator in the medium circulation circuit and the notes liquid of expansion tank independently separately, effectively avoid the gas in the medium to circulate in the medium circulation circuit always, improved exhaust efficiency.
Description
Technical Field
The utility model relates to a circulation system especially relates to a gas-liquid separation system for circulation system.
Background
In the chemical field, many chemical reactions need to be carried out under ultrahigh temperature conditions or low temperature conditions, and a circulating system communicated with a medium channel of load equipment (such as a reaction kettle) is an important factor influencing whether raw materials are fully reacted or not.
Most of the existing circulating systems are closed circulating systems, and gas-liquid separators are generally used for discharging gas in circulating media, so that bubbles in the circulating media are reduced, and the circulating effect is ensured. When the medium needs to be supplemented, the expansion tank is used for supplementing the medium to the gas-liquid separator, the newly supplemented medium circulates through a circulation loop of the gas-liquid separation system and is mixed with the circulating medium, and gas contained in the medium is discharged into the expansion tank by using an exhaust pipe inserted into the gas-liquid separator in the circulation process. However, the medium injected into the expansion tank and the medium in the circulation circuit are mixed together and circulate, so that it is difficult to discharge the gas in the medium, the discharge time is long, and the discharge is not clean.
Disclosure of Invention
An object of the utility model is to provide a gas-liquid separation system for circulation system can discharge the gas in the medium circulation return circuit fast, has improved exhaust efficiency and exhaust effect.
In order to achieve the above purpose, the utility model adopts the following technical proposal:
the utility model discloses a gas-liquid separation system for circulation system, gas-liquid separation system includes the medium circulation loop that is formed by the medium passageway of vapour and liquid separator, circulating pump, load equipment through connecting line connection, still includes the expansion tank with vapour and liquid separator intercommunication;
the gas-liquid separator is provided with a cavity for containing a medium and a liquid separation box arranged in the cavity, and the medium flows out from the outlet of the medium channel and then flows into the liquid separation box through the connecting pipeline;
the bottom exit intercommunication of expansion tank is provided with annotates the liquid pipe and its upper portion intercommunication is provided with a blast pipe, the lower part of annotating the liquid pipe extends to in vapour and liquid separator's the cavity, and the lower part of blast pipe extends to in the minute box, and is provided with the exhaust unit on being located the blast pipe in minute box.
In a preferred embodiment of the present invention, the exhaust unit includes a plurality of exhaust holes spaced apart from each other on the exhaust pipe.
In a preferred embodiment of the present invention, the exhaust pipe extends downward to a bottom wall of the liquid separation box.
The utility model has the advantages that the expansion tank adds the medium into the cavity of the gas-liquid separator through the liquid injection pipe, and the return liquid (namely the medium) in the medium circulation loop flows into the liquid separation box, so that the medium which flows back into the gas-liquid separator in the medium circulation loop and the liquid injection of the expansion tank are independently separated, further the air of the medium in the liquid separation box enters the expansion tank along with the exhaust pipe, the gas in the medium is effectively prevented from always circulating in the medium circulation loop, and the exhaust efficiency is improved; meanwhile, the lower part of the exhaust pipe is provided with an exhaust unit, so that gas contained in the medium in the loop is exhausted by the exhaust unit, the gas content in the medium is further reduced, and the exhaust efficiency is further improved.

Detailed Description
The following describes embodiments of the present invention in detail with reference to the drawings, which are implemented on the premise of the technical solution of the present invention, and detailed embodiments and specific operation procedures are provided, but the scope of the present invention is not limited to the following embodiments.
As shown in fig. 1, the gas-liquid separation system for a circulation system of the present invention comprises a medium circulation loop formed by connecting medium channels of a gas-liquid separator 1, a circulation pump 2 and a load device 3 through a connection pipeline, and further comprises an expansion tank 4 communicated with the gas-liquid separator 1;
the gas-liquid separator 1 is provided with a cavity for containing a medium and a liquid separating box 1.1 arranged in the cavity, and the medium flows out from an outlet of the medium channel and then flows into the liquid separating box 1.1 through a connecting pipeline;
the bottom outlet of the expansion tank 4 is communicated with a liquid injection pipe 5, the upper part of the expansion tank is communicated with a gas exhaust pipe 6, the lower part of the liquid injection pipe 5 extends into the chamber of the gas-liquid separator 1, and the lower part of the gas exhaust pipe 6 extends to the bottom wall of the liquid separation box 1.1.
As shown in fig. 1, an exhaust unit is arranged on the exhaust pipe 6 in the gas-liquid separator 1, the exhaust unit comprises a plurality of exhaust holes 7 arranged on the exhaust pipe 6 at intervals, the height of the exhaust hole 7 positioned at the lowest part is higher than that of the liquid separation box 1.1, and a part of gas is exhausted to the upper part of the gas-liquid separator 1, so that the gas exhaust efficiency is improved.
When a medium (the medium can be a secondary refrigerant or a heat-carrying agent) is supplemented to the medium circulation loop, the medium in the expansion tank 4 falls into a chamber of the gas-liquid separator 1 below by means of self weight; the medium in the gas-liquid separator 1 falls into the liquid separating box 1.1 in the gas-liquid separator 1 after passing through the medium channel under the action of the circulating pump 2, namely, the separation of the loop medium and the liquid injection of the expansion tank 4 is realized, so that the gas in the loop medium enters the exhaust pipe 6 above under the power action of the circulating pump 2, a part of gas is discharged to the upper space of the gas-liquid separator 1 through the exhaust hole 7, and the other part of gas is discharged to the upper space of the expansion tank 4 under the action of the circulating pump 2 and is discharged through the air hole on the filling cover 8 at the top of the expansion tank 4, and the exhaust efficiency is improved. When the liquid separating box 1.1 is filled with the medium, the medium overflows into the cavity of the gas-liquid separator 1, so that the whole medium circulation amount meets the circulation requirement of the medium circulation loop.
