Self-heating full-contact type air dehumidifying device

Abstract

The invention discloses a self-heating full-contact type air dehumidifying device, and particularly discloses an air dehumidifying device which uses high-temperature wet hot air heat. The dehumidifying device is composed of a plate type heat exchanger, an air flowing duct and a cooling dehumidifying tower. The cooling dehumidifying tower is arranged in a standing mode, a shell of the plate-type heat exchanger is fixed on the upper portion of the cooling dehumidifying tower, an air outlet of the dehumidifying tower is connected with a cold air inlet of the plate-type heat exchanger in an opposite mode, a high-temperature wet air outlet of the plate-type heat exchanger shell is connected with one end of the C-shaped air flowing duct, the other end of the air flowing duct is connected to a dehumidifying tower air inlet formed in the lower portion of the dehumidifying tower, cooling and dehumidifying are conducted in the cooling dehumidifying tower, and condensed water is collected. According to the self-heating full-contact type air dehumidifying device, cooled cold air is used for lowering the temperature of the high-temperature wet air, the humidity of the cold air is increased at the same time, and dry cold air is obtained, self heating is achieved, comprehensive utilization of energy is achieved. Compared with a traditional cooling dehumidifying device, the self-heating full-contact type air dehumidifying device saves energy by more than 90 percent, and improves utilization rate of water.

Description

technical field [0001] The invention belongs to cooling and dehumidifying equipment, in particular to an air dehumidifying device utilizing the heat of high-temperature and humid air. Background technique [0002] Traditional air-cooled dehumidification devices generally use a refrigeration system to cool high-temperature and humid air. After the temperature of the high-temperature and humid air is reduced by the refrigeration system to precipitate condensed water, the air becomes saturated moisture. In order to obtain dry gas, a steam heat exchanger is required to convert the saturated air Further heating, but the heat exchanger used in the dehumidification device is a shell-and-tube heat exchanger. The shell-and-tube heat exchanger has high manufacturing costs and requires a large heat exchange area. It is not suitable for large-flow air heat exchange, and can only be used Suitable for working conditions with small air flow. In traditional air-cooled dehumidification devi...

[0002] Traditional air-cooled dehumidification devices generally use a refrigeration system to cool high-temperature and humid air. After the temperature of the high-temperature and humid air is reduced by the refrigeration system to precipitate condensed water, the air becomes saturated moisture. In order to obtain dry gas, a steam heat exchanger is required to convert the saturated air Further heating, but the heat exchanger used in the dehumidification device is a shell-and-tube heat exchanger. The shell-and-tube heat exchanger has high manufacturing costs and requires a large heat exchange area. It is not suitable for large-flow air heat exchange, and can only be used Suitable for working conditions with small air flow

In traditional air-cooled dehumidification devices, an additional refrigeration system is used to cool down, and an additional steam heat exchanger is used to heat up, which wastes a lot of energy
