Detailed Description
In order to describe the technical contents, the achieved objects and effects of the present invention in detail, the following description will be made with reference to the embodiments in conjunction with the accompanying drawings.
Referring to fig. 1, a two-stage rotary dehumidification system based on heat pipes includes a dehumidification flow path and a regeneration wind flow path;
the dehumidifying flow path comprises a surface cooler, a dehumidifying area of the first rotary dehumidifier, a first heat pipe evaporating section, a dehumidifying area of the second rotary dehumidifier, a second heat pipe evaporating section and a temperature regulator which are sequentially arranged along the fresh air flowing direction;

From the above description, the heat pipe-based two-stage rotary dehumidifier has the beneficial effects that the two-stage rotary dehumidifier is included in the heat pipe-based two-stage rotary dehumidifier, and deep dehumidification can be realized. The fresh air is primarily cooled by the surface cooler and then enters a dehumidifying area of the first rotary dehumidifier to be primarily dehumidified, the dehumidifying efficiency of the first rotary dehumidifier can be improved after the fresh air is cooled by the first heat pipe evaporating section, the dehumidifying efficiency of the second rotary dehumidifier can be improved after the dehumidified fresh air enters the dehumidifying area of the second rotary dehumidifier, the temperature of the fresh air after the rotary dehumidifier is increased can influence the environmental temperature after the fresh air is discharged, and the regulating range of the temperature regulator is limited, so that the fresh air after the dehumidification of the dehumidifying area of the second rotary dehumidifier enters the second heat pipe evaporating section to be cooled, and then enters the temperature regulator to regulate the air supply temperature to meet the temperature requirements in different occasions.
The regeneration air of the regeneration zone of the rotary dehumidifier is regenerated through the regeneration air flow path, the regeneration air is firstly heated through the condensation section of the second heat pipe in the regeneration process, the energy consumption of the primary regeneration heater can be reduced, then the regeneration air is heated to the regeneration temperature through the primary regeneration heater and enters the regeneration zone of the second rotary dehumidifier, the regeneration efficiency of the regeneration zone of the second rotary dehumidifier can be improved, the temperature of the air after the first regeneration is reduced to some extent, and the humidity is increased, so that the air enters the regeneration zone of the first rotary dehumidifier for regeneration after being heated by the condensation section of the first heat pipe and the secondary regeneration heater, and the regeneration air is suitable for high-temperature and low-temperature scenes. In the system, the cooling effect of the evaporation section of the heat pipe and the heating effect of the condensation section of the heat pipe are fully utilized, compared with a single heat pump or heat pipe, the heat exchange efficiency is higher, the energy conservation is more remarkable, and as the second heat pipe and the first heat pipe can respectively realize different temperatures, the temperature of the condensation section of the first heat pipe can be set higher than that of the condensation section of the second heat pipe, so that the air with higher humidity after the first regeneration is subjected to the second regeneration.
Further, the dehumidification flow path further comprises a first filter, a first fan and a second fan, wherein the first filter, the surface cooler, a dehumidification area of the first rotary dehumidifier, the first fan, the first heat pipe evaporation section, a dehumidification area of the second rotary dehumidifier, the second fan, the second heat pipe evaporation section and the temperature regulator are sequentially arranged along the air supply direction of the dehumidification flow path.
As can be seen from the above description, since the two-stage rotary dehumidifier has a large resistance, only one fan is provided, the pressure head of the fan is insufficient, and the air path is not smooth, the first fan is provided behind the dehumidification area of the first rotary dehumidifier, and the second fan is provided in the dehumidification area of the second rotary dehumidifier, so that the air path is smooth. The impurity in the new trend can be got rid of to first filter, prevents that impurity from influencing the life-span of two-stage runner dehumidification system.
Further, the regeneration wind flow path further comprises a second filter and a regeneration fan, and the second filter, the second heat pipe condensation section, the first-stage regeneration heater, the regeneration zone of the second rotary dehumidifier, the first heat pipe condensation section, the second-stage regeneration heater, the regeneration zone of the first rotary dehumidifier and the regeneration fan are sequentially arranged along the air supply direction of the regeneration wind.
Further, the first heat pipe evaporation section and the first heat pipe condensation section form a first heat pipe, the second heat pipe evaporation section and the second heat pipe condensation section form a second heat pipe, and the first heat pipe and the second heat pipe are gravity type heat pipes.
From the above description, the gravity type heat pipe has high heat transfer efficiency, and the condensing section has higher temperature, so that the energy consumption of the regenerative heater can be greatly saved.
According to the regulating and controlling method (dehumidifying method) of the two-stage rotating wheel dehumidifying system based on the heat pipes, when the regulating and controlling method is in a summer dehumidifying mode, a surface cooler, a dehumidifying area of a first rotating wheel dehumidifier, a first heat pipe evaporating section, a dehumidifying area of a second rotating wheel dehumidifier, a second heat pipe evaporating section and a temperature regulator are started on a dehumidifying flow path, and a second heat pipe condensing section, a first-stage regenerative heater, a regenerating area of the second rotating wheel dehumidifier, a first heat pipe condensing section, a second-stage regenerative heater and a regenerating area of the first rotating wheel dehumidifier are started on a regenerating air flow path.
From the above description, the summer dehumidification mode is suitable for operation under a summer fresh air dehumidification condition or under high temperature and high humidity, and the summer dehumidification mode is used for dehumidifying air with humidity higher than 30 ℃ and humidity higher than 30%.
Further, when the regulation is in a winter dehumidification mode, a surface cooler, a dehumidification area of the first rotary dehumidifier, a first heat pipe evaporation section and a temperature regulator are opened on a dehumidification flow path;
The regeneration air flow path opens the first heat pipe condensation section, the second-stage regeneration heater and the regeneration area of the first rotary dehumidifier;
the regeneration zone of the first rotary dehumidifier is connected with the surface cooler.
From the above description, it can be seen that the winter dehumidification mode is suitable for a scene where the fresh air temperature is low in winter environment, but the humidity in the air does not reach the supply dew point requirement, and dehumidification is still required, and the winter dehumidification mode dehumidifies the air with the fresh air temperature of 0-15 ℃ and the humidity higher than 30%. Because the fresh air temperature is lower, the wet load under the working condition in winter is lower simultaneously, the fresh air does not need to be cooled and dehumidified for a plurality of times, and only the first rotary dehumidifier is used for dehumidification. Because the fresh air temperature in winter is lower, the fresh air directly enters the rotating wheel and possibly causes the rotating wheel to freeze, and therefore, the fresh air needs to be mixed with the regeneration air with higher temperature and then enters a dehumidification area of the first rotating wheel dehumidifier for dehumidification.
Further, when the regulation is in a spring and autumn dehumidification mode, a surface cooler, a dehumidification area of the first rotary dehumidifier and a temperature regulator are opened on a dehumidification flow path;
the second heat pipe condensation section, the first regeneration heater, the regeneration zone of the second rotary dehumidifier and the first heat pipe condensation section are closed.
From the above description, the dehumidifying mode in spring and autumn is suitable for the temperature of fresh air in spring and autumn between the higher temperature in summer and the lower temperature in winter, so that a heat pipe is not needed for cooling or heating, and proper dehumidifying temperature and regeneration temperature can be obtained under the action of a surface cooler and a regeneration heater. The dehumidifying mode is used for dehumidifying air with fresh air temperature of 15-25 ℃ and humidity higher than 30%.
