Cotton mill air-conditioning dust collection automatic control system

Abstract

The invention discloses an automatic control system for air-conditioning dust removal in a cotton spinning mill, which includes a pipe connecting the controlled workshop of the cotton spinning mill and an air-conditioning room, and a temperature and humidity sensor and an enthalpy transmitter are arranged at the fresh air inlet of the air-conditioning room; Air valves, return air valves, and fresh air valves are equipped with electric actuators for air valves; electric valves are installed on the water supply pipes and steam pipes in the air-conditioning room; the air volume of the sending and returning fans is controlled by frequency converters; A dew point temperature sensor is set after the spray section of the room; a direct digital controller is set near the air-conditioning room. The invention has the advantages of greatly saving energy consumption of water, electricity, steam, cold source and heat source. It can save more than 40% energy for air conditioners in textile factories. High precision control of temperature and humidity in textile process. The control accuracy is within ±0.5°C for temperature and within ±3% for relative humidity. Greatly improved the quality of finished and semi-finished textile products. Greatly reduced labor costs.

Description

technical field [0001] The invention relates to an automatic control system, in particular to an automatic control system for air-conditioning and dust removal in cotton spinning mills. Background technique [0002] my country is a large textile country. Many cotton spinning mills were built in the early days of the founding of the People's Republic of China. Due to the historical conditions at that time, until now, the air conditioning and dust removal systems of cotton spinning mills are basically manually adjusted. This primitive working method causes waste of energy, increased labor cost and too low accuracy. Moreover, many textile equipments at this stage have high requirements on the accuracy of temperature and humidity. The air-conditioning and dust removal control system in cotton spinning mills currently used cannot meet the needs of modern mass production, which often makes it difficult to open workshop equipment. Contents of the invention [0003] The purpose o...
