Description

Styrene external refrigeration cycle transceiver system

technical field

The utility model relates to the technical field of refrigeration cycles, in particular to a styrene external refrigeration cycle transceiver system.

Background technique

When the temperature in the environment is high, the styrene in the styrene storage tank will polymerize. In order to prevent the polymerization of styrene, a refrigeration system is generally installed in the styrene storage tank, but each styrene storage tank Installing a refrigeration system inside makes the cost higher.

Utility model content

Aiming at the above technical problems, the utility model provides a low-cost and easy-to-use styrene external refrigeration cycle transceiver system.

In order to achieve the above object, the technical solution of the utility model is: a styrene external refrigeration cycle transceiver system, including a plurality of styrene storage tanks, a first valve, a feed pipe, a discharge pipe, a second valve and a refrigeration system, The feed pipes are respectively communicated with each styrene storage tank, each of the styrene storage tanks is connected in series with the first valve and then connected in parallel, and the second valve is connected in series on the pipeline after the styrene storage tanks are connected in parallel. One end of the system is communicated with the second valve, and the other end of the refrigeration system is also communicated with the parallel-connected pipeline of the styrene storage tank.

According to the above scheme, it can be seen that the utility model has the following advantages: such a design can ensure normal feeding and discharging, and when there is no need for external discharging, the first valve can still be opened and the second valve can be closed to feed styrene into the refrigerator. system for freezing. At this time, not only can styrene enter the original storage tank, but also the styrene can enter another storage tank by closing the first valve on the original storage tank and opening the first valve on the other storage tank, so that the design can The styrene in a plurality of styrene storage tanks is frozen by an external refrigeration system, and the cost is low and the use is convenient.

Preferably, the refrigeration system includes a refrigerated liquid storage tank and a heat exchanger, and the refrigerated liquid storage tank is connected in series with the heat exchanger; the structure is simple, the installation is convenient, and the cost is low.

As an improvement, it also includes a third valve, the third valve is connected in series on the passage of the pipeline after the refrigeration system is connected in parallel with the styrene storage tank; the third valve can be closed when the styrene is discharged to prevent the original need to discharge The styrene of the feed enters the refrigeration system.

Preferably, the number of the styrene storage tanks is four; a good freezing effect can be achieved for the styrene in each styrene storage tank.
