The project is located in Shaoyang, Hunan, with an annual output of 14,000t of colloidal emulsion explosives. This project is divided into emulsion explosive production workshop (104#), with a production hazard level of 1.1; water-oil phase preparation workshop (103#), with a production hazard level of 1.4. Among them, the 104# workshop belongs to the follow-up processing and production workshop, and a new air-cooled heat pump post air supply system is designed; the 103# workshop is a water-oil phase preparation workshop. The steel strip production line needs to provide process ice water for cooling, and an air-cooled screw type is designed. Chiller process cooling system.

1. The split explosion-proof air-cooled heat pump cabinet air-conditioning unit is adopted, and the hot and cold air is directly sent to each work position through the post air supply system to improve the energy utilization rate, which not only meets the heating and cooling needs of the workshop in winter and summer, At the same time, safety production is realized for the use occasions.

2. The process cooling system adopts air-cooled screw refrigeration unit + energy-saving system in transition season and winter. In transition season and winter, cooling tower is used for cooling, which can save more than 40% of refrigeration energy consumption in one year.
