Abstract

The invention relates to a heat pipe vacuum drying system and application thereof, and belongs to the field of sewage treatment. The heat pipe vacuum drying system comprises a heat pipe heating area I, a heat pipe condensing area II, a heat recovery area second section III, a phase change area IV, a heating area V and a stock solution tank. The heat pipe heating area I comprises a heating tank anda first heat pipe. The heat pipe condensing area II comprises an evaporating tank and a second heat pipe. The first heat pipe and the second heat pipe form a heat pipe cycle. The heat recovery area second section III comprises a recovery tank and a heat exchange tank. The stock solution tank is connected with the recovery tank through a first pipeline. The outlet of the recovery tank is connectedwith the evaporating tank. The evaporating tank is connected with the phase change area IV. The phase change area IV comprises a condensate water tank and a liquid level meter. The condensate water tank is connected with the heating tank through the heating area V. The outlet of the heating tank is connected with the heat exchange pipe. The outlet of the heat exchange pipe conducts discharging through a drainage pipe for secondary utilization. The bottom of the evaporating tank is connected with a concentrated liquid storage tank. Salt and water in sewage are separated, processed water can beused again, and the system is high in processing efficiency and safe and saves energy.

Description

Technical field [0001] The invention relates to a heat pipe vacuum drying system and its application. It is mainly applied to the further concentration process in the desalination process of concentrated sewage in advanced sewage treatment, and belongs to the technical field of sewage treatment. Background technique [0002] With the rapid development of society, various industries, such as papermaking, chemical industry and other chemical companies, inevitably produce a lot of industrial sewage in the production process. The discharge of industrial sewage seriously pollutes groundwater and surface water, which brings harm to people’s lives and health. Greatly bad influence. Water pollution continues to intensify. The efficient treatment of sewage and the cleanliness of the resulting products have always been issues of great concern to people, as well as technical problems that urgently need to be overcome. [0003] There are a large number of sewage treatment equipment in the pri...
