Abstract
The invention provides a heat pump type spraying solution dehumidification system which is implemented as follows: the solution is pressurized and conveyed to atomization spraying nozzles in a dehumidification box body and a regeneration box body through pipelines, the atomization spraying nozzles are used for spraying out atomization solution, and the atomization solution performs heat and mass transfer exchange together with processed air and regenerated air respectively, the dehumidification box body performs dehumidification on the processed air, and the regeneration box body performs regeneration and concentration on the solution for recycling. The heat pump type spraying solution dehumidification system abandons the traditional method that filling material is placed in an air passage to perform heat and mass transfer exchange with the solution, so as to enable the gas-liquid contact surface area to be improved by at least 10% compared with that by adopting the filling material, since the filling material is not used, the resistance of the air passage is reduced by more than 50%, and maintenance is simple and convenient; due to improvement on heat and mass transfer coefficients, and reduction of the resistance of the air passage, the structure is compact, energy is totally saved by 10-20%, and initial investment and operation cost of the whole system can be greatly reduced. According to the system, an evaporator and a condenser of a heat pump system can be utilized for providing a cold source and a heat source respectively, water vapour and industrial waste heat can be also taken as the heat source, and groundwater and an indirect evaporative water chilling unit can be utilized for providing the cold source.

Technical field
The present invention relates to a kind of pump type heat spray air dehumidification system, is specifically a kind of atomizing solution dehumidification system.
Background technology
The solution dehumidification system that uses at present, the characteristic of utilizing solution to absorb moisture in air is carried out dehumidifying work; Usually filler is placed in the air channel, solution on filler, carries out the heat and mass exchange with air by the pump spray, absorbs airborne moisture, and the solution after dilution heats concentrated again, circular flow.This system mainly has the following disadvantages:
1. carry out the heat and mass exchange by moisture film and air in filler, exchange area is limited, and exchange efficiency is low;
2. exist the contradiction of flowing resistance and heat and mass ability in the selection of filler.Be the good filler of heat and mass ability, its flowing resistance is large; The filler that flowing resistance is little, its heat and mass ability is poor again.
3. along with the growth of running time, the calcium magnesium inorganic salts in solution and impurity constantly stick on filler, stop up filler and increase gas-flow resistance, affect the heat and mass effect, and the heat and mass ability is descended.
4. the multiplex plastic production of filler, the distortion of plastics, press fall into, aging, cause filler broken, lose the heat and mass ability, blocking pipe causes fault, thereby needs to clean and change filler, has improved maintenance cost.
5. when solution drenched filler, the surface area of solution was fixed, and when increasing sprinkle density, the solution film unstability forms fluctuation, and wave amplitude is several times as much as film thickness, forms channel, and gas-flow resistance is sharply increased.Due to airflow obstruction, serious reduction the heat and mass effect.
Summary of the invention
The problem that exists in order to overcome traditional solution dehumidification system the invention provides a kind of simple in structure, energy-efficient pump type heat spray air solution dehumidification system.
