Surface air cooler serialization design method for air compressor air inlet pretreatment

Abstract

The invention discloses a surface air cooler serialization design method for air inlet pretreatment of an air compressor. The method specifically comprises steps of calculating the cooling capacity Qof a surface air cooler according to the air yield G of the air compressor: determining the coil parameters of the surface air cooler according to the cooling capacity Q of the surface air cooler; calculating total heat efficiency E'g which can be achieved by the surface air cooler according to the gas production rate G, the surface air cooler coil parameters, the air parameters and the fluid parameters, and verifying the total heat efficiency E'g which can be achieved by the surface air cooler by utilizing the required total heat efficiency Eg. Under the condition of not changing equipment original parts, the air quality can meet the temperature, humidity and pressure requirements of air inlet of the air compressor by changing the size and specification of the cooling equipment accordingto the change of the air yield caused by the difference of the models of the air compressor; the surface air cooler suitable for air compressors with different gas production rates can be rapidly designed, and design and manufacturing cost is reduced.

Description

Technical field[0001]The invention belongs to the technical field of heat exchange equipment design methods, and relates to a surface cooler serialized design method for air compressor intake pretreatment.Background technique[0002]The air source of the air compressor comes from the atmosphere. As a power source, it has the characteristics of non-toxic, harmless, safe, compressible, and convenient to use. Compressed air is called the fourth public utility, and it plays an important role in modern society. Compressed air accounts for about 10% of the total energy used in today's industry. Air compressors are widely used in the air compressor system of the textile industry. The energy consumption of the air compressor system in textile enterprises accounts for more than 30% of the overall energy. As a large textile country, 70% of the textile industry is located in the Yangtze River Delta, the Pearl River Delta and other regions. The Pearl River Delta is located in my country's high-te...

AI Technical Summary

Problems solved by technology

Most of the textile mills only carry out simple filtration, dust removal, and noise reduction treatment on the incoming air, and do not consider the temperature and humidity pretreatment of the incoming air, let alone design pretreatment for the difference in the air output of the air compressor The method of equipment, if the pretreatment equipment of the air compressor is not suitable, it will also reduce the working efficiency of the air compressor
