Description
Technical Field
The invention belongs to the technical field of air treatment, and particularly relates to a total heat recovery type cold and hot combined supply dehumidification device and method.
Background
The most widespread air dehumidification is by a cooling dehumidification method. The cooling and dehumidifying principle is to utilize a refrigeration compressor to continuously provide a cold source for the air heat exchanger, reduce the dew point temperature of air flowing through the heat exchanger, enable moisture in the air to condense into water drops on the surface of the heat exchanger, circulate in this way and reduce the moisture content in the air to a certain extent.
In the industrial field, in order to obtain air with lower relative humidity, the use requirement cannot be met only by a cooling and dehumidifying method, so that a serial scheme of combining cooling and dehumidifying with rotating wheel dehumidifying is commonly adopted in an industrial dehumidifier, and the wet air is subjected to cooling and dehumidifying before passing through the rotating wheel to physically adsorb water in the air, so that dry air with ultralow dew point is obtained.
The runner is a corrugated honeycomb runner which is made of special composite heat-resistant materials and is loaded with a moisture absorbent, and the honeycomb runner has the characteristics of large moisture absorption specific surface area, small flow resistance, high dehumidification efficiency and the like. The two sides of the wheel are divided into two sectors by a high-tightness baffle plate: an air handling sector and a regeneration recovery sector. When the processing air to be dehumidified enters the processing sector, the water vapor in the air is adsorbed by the carrier in the rotating wheel to be dried, the latent heat is released, and the dried air is sent out of the system through the fan. As the absorbed moisture increases, the rotor treatment sector tends to saturate with humidity, and in order to maintain its stable dehumidification performance, the saturated rotor portion is turned into a regeneration zone under the drive of a motor, and the regeneration process of the rotor absorbent is started. The regenerated air is heated by the regeneration heater to 100-140 ℃, reversely blows into the regeneration area, desorbs adsorbed moisture in the rotating wheel at a high temperature state, simultaneously releases a large amount of sensible heat, reduces the temperature of the air to become wet air saturated with moisture, and discharges the wet air, thereby completing the transfer of the moisture, recovering the strong moisture absorption capacity of the rotating wheel, and then transferring the rotating wheel into the working area for dehumidification. The dehumidification and regeneration processes are carried out simultaneously, air is continuously dried, the rotating wheel is continuously regenerated, and the processes are repeated, so that the continuous and constant working state of the dehumidifier is ensured.
The traditional industrial dehumidifier is characterized in that a cold source and a heat source are respectively obtained through a cold-hot separation scheme, the cold source is generated by a refrigerating unit, the refrigerating unit provides the cold source, and meanwhile, the generated condensation heat load is discharged into the air by a cooling tower or evaporative cooling, so that the energy loss is serious; on the other hand, the thermal load of the regenerative heater of the dehumidifier wheel is obtained by electric heating or high-temperature steam, and the thermal efficiency is not high.
