Municipal wastewater and municipal ground source cooperation type heat exchange system

Abstract

The invention relates to a municipal wastewater and municipal ground source cooperation type heat exchange system. According to the municipal wastewater and municipal ground source cooperation type heat exchange system, two-way use of heat energy of municipal wastewater and heat energy of a ground source can be realized, and surplus heat energy of the wastewater can be stored in soil. A novel sustainable energy supply system is realized through interaction of the heat energy of the wastewater and the heat energy of the ground source. The novel wastewater heat exchange system comprises a heat exchanger, a heat supply system, a heat supply loop, a heat user, wastewater pipelines and a blow-down tank. The service life of the municipal wastewater heat exchange system is greatly prolonged, the installation procedure is simplified, the energy utilization rate is increased, municipal carbon dioxide emission is reduced, and municipal water resources are protected. The light-weight wastewater heat exchange system saves energy, reduces emission and is free of pollution.

Description

technical field [0001] The invention belongs to an urban sewage and urban ground source coordinated heat exchange system, in particular to a quick-connect sewage heat exchange device with high corrosion resistance and long service life. Background technique [0002] With the rapid development of the economy, the total energy consumption in my country and the world is increasing year by year, and the massive consumption of fossil fuels has brought about serious environmental pollution problems. The problem of energy shortage and environmental pollution has become an important issue in today's world. Therefore, the utilization and vigorous development of clean and renewable energy has become a development trend and an important way to achieve energy conservation and environmental protection. Heat pump technology, especially sewage source heat pump technology that uses urban sewage heat energy as a low-grade heat source / cold source for heating / cooling, has become one of the eff...

AI Technical Summary

Problems solved by technology

[0003] The existing sewage source heat pump technology has short service life, poor air tightness, complex installation, rotation and fixation, lack of flexibility, weak chemical corrosion resistance, and high requirements for sewage water quality

In previous studies, some heat pump systems added sewage filtration devices and used the filtered sewage to directly exchange heat with refrigerants. However, the filtration devices in this method often consume a lot of energy such as electric energy, and the filtering effect is not very good. Ideal, it is difficult to meet the water quality requirements of direct sewage heat exchangers for sewage, so developing a heat exchange device that can directly exchange heat with raw sewage is an effective way to reduce energy consumption and improve the thermal efficiency of heat pumps
