Sterile double-pipe plate heat exchanger

Abstract

The invention discloses a sterile double-pipe plate heat exchanger. The sterile double-pipe plate heat exchanger comprises a heat exchanger main body; a pipe body is arranged at the external end of the heat exchanger main body; a heat exchange pipe is arranged at the internal end of the pipe body; the two ends of the heat exchange pipe are connected and provided with a heating medium inlet and a heating medium outlet; the pipe body is connected and provided with a refrigerant inlet and a refrigerant outlet; the heating medium inlet and the heating medium outlet are provided with pipe plates; pipe boxes are mounted on the pipe plates; and sterilization lamps are arranged in the pipe boxes. The sterile double-pipe plate heat exchanger is simple and reasonable in structure, convenient to useand install, excellent in connecting tightness, not easy to leak, incapable of generating cross infection and bacteria breeding, high in sterility and accordant with the production sanitation demands.

Description

technical field [0001] The invention relates to a sterile double-tube plate heat exchanger, which belongs to the technical field of heat exchangers. Background technique [0002] A heat exchanger is a device that transfers part of the heat of a hot liquid to a cold liquid, also known as a heat exchanger. Heat exchangers play an important role in chemical, petroleum, power, food and many other industrial productions. In chemical production, heat exchangers can be used as heaters, coolers, condensers, evaporators and reboilers, etc., and are widely used However, the tightness between the tube connections of the traditional double-tube plate heat exchanger is low, which makes the hot medium and the cold medium mix, causing cross-contamination and bacteria, and the heat exchange tubes will also produce bacteria after long-term use. Especially in medical treatment and food production, the technical requirements of medical hygiene and food hygiene cannot be met, which brings inco...

Problems solved by technology

Heat exchangers play an important role in chemical, petroleum, power, food and many other industrial productions. In chemical production, heat exchangers can be used as heaters, coolers, condensers, evaporators and reboilers, etc., and are widely used However, the tightness between the tube connections of the traditional double-tube plate heat exchanger is low, which makes the hot medium and the cold medium mix, causing cross-contamination and bacteria, and the heat exchange tubes will also produce bacteria after long-term use. Especially in medical and food production, it cannot meet the technological requirements of medical hygiene and food hygiene, which brings inconvenience to production and reduces product grades.
