Problems solved by technology

[0002] At present, the nitrogen and oxygen used in the solar cell processing technology are both liquid and need to be gasified and pressurized before they can be used in the workshop. During the gasification process, the liquid nitrogen and liquid oxygen condense a layer of dew on the periphery of the vaporization device. Time It will freeze for a long time, affecting gasification; at the same time, the cooling water treatment required in the processing process requires ice machine refrigeration. The power of the ice machine is 50 kW / h, and it is turned on 24 hours a day, consuming a lot of power resources every day.

Embodiment

[0015] The temperature of nitrogen or oxygen required for solar cell processing is 0-25°C and the pressure is 0.5-7kg / cm 2 , when liquid nitrogen or oxygen enters the vaporization device from the storage tank, the temperature is -190°C and the pressure is 2-3kg / cm 2 , The temperature of the cooling water coming out of the workshop is 30-40°C, and it enters the cooling tower for preliminary cooling and enters the reservoir. The liquid nitrogen or oxygen absorbs the temperature of the cooling water in the reservoir to normal temperature through the vaporization device, and the cooling water absorbs heat through the vaporization device in the reservoir to reduce the temperature and play a cooling role.

Abstract

The invention discloses a solar cell sheet processing hydraulic condensation circulation system. The solar cell sheet processing hydraulic condensation circulation system includes a liquid nitrogen circulation system, a liquid oxygen circulation system and a cooling water circulation system; and liquid nitrogen or oxygen absorbs heat of cooling water in a water reservoir through vaporization devices, so that the temperature of the cooling water is decreased to normal temperature. The temperature of the cooling water in the water reservoir is decreased through heat absorption of the vaporization devices, so that a cooling effect can be realized. The solar cell sheet processing hydraulic condensation circulation system of the invention has the advantages of simple structure, safe use and gasification and cooling combination, can assist in saving resources.

Description

technical field [0001] The invention relates to the technical field of solar cell processing, in particular to a hydraulic condensation cycle system for solar cell processing. Background technique [0002] At present, the nitrogen and oxygen used in the solar cell processing technology are both liquid and need to be gasified and pressurized before they can be used in the workshop. During the gasification process, the liquid nitrogen and liquid oxygen condense a layer of dew on the periphery of the vaporization device. Time It will freeze for a long time, affecting gasification; at the same time, the cooling water treatment required in the processing process requires ice machine refrigeration. The power of the ice machine is 50 kW / h, and it is turned on 24 hours a day, consuming a lot of power resources every day. Contents of the invention [0003] The object of the present invention is to provide a hydraulic condensation cycle system for processing solar cells with simple ...
