Description

Technical Field

[0001] This utility model relates to the field of propylene liquid condensation technology, specifically to a propylene liquid condensation controllable cooling capacity cooler. Background Technology

[0002] A propylene condenser is a device used to cool propylene gas and convert it into a liquid state. It is typically used in conjunction with a reaction unit to collect and treat the condensate and exhaust gases produced by the reaction. It ensures that the exhaust gases are adequately treated to meet emission standards and effectively prevents the escape of unreacted exhaust gases.

[0003] Currently, the amount of condensate / water supplied to the cooler used for propylene liquid condensation on the market is fixed and uncontrollable. That is, when the temperature of the condenser tube is low or has reached the required standard for condensation, a large amount of condensate will still be supplied from the outside according to the previously preset information. This will cause the temperature of the condenser tube used for conversion cooling to continue to drop, resulting in it being lower than the temperature for cooling propylene gas and converting it into liquid, which will lead to the risk of over-condensation conversion.

[0004] Therefore, it is necessary to design a propylene liquid condenser with controllable cooling capacity to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this invention is to provide a propylene liquid condenser with controllable cooling capacity, which makes the cooling capacity inside the condenser controllable and avoids excessive propylene condensation and conversion, thereby solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A propylene liquid condenser with controllable cooling capacity includes a condenser body. A feed inlet and a condensate inlet are respectively provided on the upper side of one side of the condenser body, and a discharge outlet and a condensate outlet are respectively provided on the lower side of the other side of the condenser body. A feed pipe and a condensation pipe are respectively provided inside the condenser body, and the condensation pipe is wrapped around the feed pipe. A fixing bracket is also fixedly installed on the outer side of the condenser body. A controller is embedded in the outer shell of the condenser body.

[0008] As a preferred embodiment of this utility model, one side of the material tube is fixedly connected to and communicates with the bottom of the inlet, and the other side is fixedly connected to and communicates with the top of the outlet.

[0009] As a preferred embodiment of this utility model, one side of the condenser tube is fixedly connected and communicates with the bottom of the condensate inlet, and the other side is fixedly connected and communicates with the top of the condensate outlet.

[0010] As a preferred embodiment of this utility model, a three-way valve is also provided on the condensate outlet. One side outlet of the three-way valve is connected to the bottom outlet end of the condensate outlet, and the other side outlet is connected to a circulation pipe, which is connected to a circulation pump. The side of the circulation pipe away from the circulation pump is connected to the condensate inlet.

[0011] As a preferred embodiment of this utility model, a solenoid valve is provided on the condensate inlet, and the solenoid valve and the controller are electrically connected.

[0012] As a preferred embodiment of this utility model, a temperature sensor is provided on the condenser tube, and the temperature sensor and the controller are electrically connected.

[0013] As a preferred embodiment of this utility model, the controller is internally equipped with a processor and a memory.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] In this invention, a controllable cooling capacity cooler for propylene liquid condensation is provided. When using this cooler, propylene is added from the inlet into the feed pipe located inside the cooler body. Condensate flows inside the condenser pipe. Driven by a circulating pump, the condensate cools the condenser pipe, which condenses the propylene inside the feed pipe and converts it into liquid. The temperature value of the condenser pipe is obtained by a temperature sensor. When the temperature value is lower than the preset temperature value stored in the memory, the solenoid valve is controlled to reduce its opening degree, thereby reducing the entry of condensate. Conversely, when the temperature value is higher than the preset temperature value, the solenoid valve is controlled to increase its opening degree, thereby increasing the entry of condensate. This makes the cooling capacity of the cooler controllable. Attached Figure Description
