Description

TECHNICAL FIELD

[0001] The utility model relates to the cooling water circulation technical field, especially relates to a pitch production cooling water recycling device. BACKGROUND

[0002] In the pitch production process, a large amount of high-temperature cooling water is usually generated, which absorbs a large amount of heat when cooling the production equipment, thus containing a certain amount of heat energy and impurities. If this cooling water is directly discharged without treatment, not only water resources are wasted, but also the environment is polluted.

[0003] The existing cooling water circulation technology mostly uses disposable cooling water, which is then discharged into the environment. However, this method not only wastes water resources but also may cause environmental pollution. For example, a Chinese patent "Modified pitch production plant emulsified pitch cooling water recycling device" (application number CN202022748079.X) uses the cooling water in the cooling water tower to transport to the condensing tower. The cooling water in the condensing tower can effectively absorb the temperature of the emulsified pitch to achieve the purpose of cooling. Under the condition that the cooling water pump is continuously working, the water in the condensing tower after temperature replacement is transported to the cooling water tower through the backwater pipe for rapid cooling, and then transported to the condensing tower through the cooling water pump. However, during pitch production, pitch inevitably enters the water pump with the cooling water. The pitch and impurities in the cooling water cannot be effectively separated and filtered, which leads to a decrease in the quality of the recycled cooling water and easily blocks the pipeline, causing damage to the circulation system.
