An energy-saving industrial circulating water system and its operation method

Abstract

The invention discloses an energy-saving industrial circulating water system, and relates to the technical field of circulating water systems and their operating methods. In order to solve the most unfavorable conditions of current domestic circulating water systems, such as the maximum output of each unit, the highest variety and specification, and the highest temperature, etc. Conditional commissioning and operation, the temperature difference between the circulating water supply and return water is small, which brings a lot of energy waste. A water supply pipe is provided above the water collecting tank, a sewage discharge pipe is provided below the water collecting tank, a cooling tower is provided on one side of the water collecting tank, and a return pipe passes between the cooling tower and the water collecting tank Sealed connection, a heat exchanger is provided on one side of the cooling tower, and the heat exchanger is sealed with the water collection tank through the outlet pipe of the water collection tank, and the heat exchanger and the cooling tower are connected through a heat exchanger The outlet pipe is sealed and connected, a self-cleaning filter is installed on the return pipe, and a side flow pipe is sealed and installed on one side of the return pipe.

Description

technical field [0001] The invention relates to the technical field of circulating water systems and operating methods thereof, in particular to an energy-saving industrial circulating water system and operating methods thereof. Background technique [0002] Industrial circulating water is mainly used in cooling water systems, so it is also called circulating cooling water. Because industrial cooling water accounts for more than 90% of the total water consumption. There are two types of circulating cooling water: closed type (closed type) and open type. In the closed cooling water system, the cooling water is not exposed to the air, the water loss is very small, and the contents of various minerals and ions in the water generally do not change. In the open circulating water system, the recooling of water is carried out through the cooling tower, so the cooling water must be in contact with the air during the recirculation process, and part of the water will continue to be ...
