Abstract

The invention relates to pre-cooling equipment, in particular to cold box pre-cooling equipment for natural gas liquefaction for chemical engineering. The technical problem is to provide the cold box pre-cooling equipment for natural gas liquefaction for chemical engineering, which does not affect the environment. Cold box pre-cooling equipment for natural gas liquefaction for chemical engineering comprises a cold box and a gas inlet pipe, and the gas inlet pipe is fixedly connected to the lower portion of one side of the cold box; the mounting seat is fixedly connected to one side of the inner wall of the cold box, and the air inlet pipe is fixedly connected with the mounting seat; and the compressor is mounted on the mounting seat. The filtering mechanism can filter air, dust in the air is prevented from entering the compressor, the compressor can cool the air, the heat exchange mechanism can also cool the air, and therefore the environment in the cold box is refrigerated, the water cooling mechanism can cool redundant hot air, and the cooling efficiency is improved. Redundant hot air is prevented from being directly discharged to the outside, and the environment is prevented from being influenced.

Description

technical field [0001] The invention relates to a precooling device, in particular to a cold box precooling device for chemical natural gas liquefaction. Background technique [0002] Natural gas is a naturally occurring gas in nature. It is colorless, odorless, and non-toxic. In the chemical industry, liquefied natural gas cold boxes are often used to exchange heat between natural gas and refrigerants. The current liquefied natural gas cold box is in the cooling process. , will produce some excess hot gas, but the current liquefied natural gas cold box does not have the function of collecting excess hot gas, and the excess hot gas is directly discharged to the outside, thus causing certain pollution to the environment. [0003] In response to the current problems, we design a device that will not affect the environment. Contents of the invention [0004] In order to overcome the disadvantages that the current liquefied natural gas cold box does not have the function of c...
