Description

technical field

The utility model belongs to the technical field of solution dehumidification, in particular relates to an integrated device for air dehumidification and dust removal.

Background technique

Conventional air-conditioning systems usually use chilled water at 7 ^o C to process humid air through heat and moisture exchange equipment such as contact (water spray booths) or surface (air handling coils). The sensible heat load and humidity load are removed by cooling and dehumidifying the humid air. The air handling equipment, especially the air handling coils, usually operate under wet conditions, which not only requires the chiller to have a very low evaporation temperature, but also the surface of the coils is prone to bacteria breeding, resulting in poor air quality. In order to solve the above problems, the heat and humidity independent treatment method came into being. This method can separate the air humidity load and the sensible heat load, which greatly improves the dehumidification efficiency and energy efficiency ratio of the system, and the solution dehumidification is used as heat and humidity treatment. An effective method has received widespread attention.

On the other hand, since the 1980s, intelligent buildings integrating modern office, communication and automatic control have gradually emerged. Here comes a serious challenge. This not only requires heat and humidity treatment of the air, but also ensures good air quality indoors. At present, air filters are mostly used to deal with particulate matter and pollutants in the air. However, adopting this method not only needs to add an additional set of devices, but also, because the air filter has relatively large resistance, it often purifies the air at the cost of sacrificing the energy consumption of the blower fan, resulting in a waste of energy.

Therefore, if the solution dehumidification and dust removal can be integrated into a set of equipment, not only can the equipment be simplified, but also a large amount of energy can be saved.

In the jacketed heat exchanger 26, the solution exchanges heat with the high-temperature liquid flowing through the jacketed heat exchanger 26, so that the solution evaporates part of the gas and raises its temperature. The solution changes from a dilute solution to a concentrated solution. The heated solution enters the gas-liquid separator 27 , and part of the evaporated gas is discharged through the opening 29 of the gas-liquid separator 27 . The solution flows into the first solution distributor 22 and the second solution distributor 23 through the first electric valve 30 and the second electric valve 33, and the solution flowing out from the first solution distributor 22 and the second solution distributor 23 flows out from the first solution distributor 22 and the second solution distributor 23.

By setting the first electric valve input end 31 and the second electric valve input end 34 , the amount of solution distributed in the first solution distributor 22 and the second solution distributor 23 can be realized. When the moisture content of the air is high, the opening degree of the second electric valve 33 is increased, so that more solution flows into the second solution distributor 23 . When the dust content in the air is large, the opening degree of the first electric valve 30 is increased, so that more solution flows into the first solution distributor 22 . By automatically setting the first electric valve 30 and the second electric valve 33 to different opening degrees, the ratio of dehumidification and dust removal liquids can be adjusted.

The above connection device also includes a filter 24 connected in the first pipeline, and the filter output end 42 of the filter 24 is connected with the solution pump input end 44 . Since the solution output from the first solution output port 7 contains dust, a filter 24 is provided for filtering the dust in the solution. Similarly, the solution output from the second solution output port 8 also contains a small amount of dust, and the dust in the solution is filtered by the filter 24 . In this way, when the solution is reused for dehumidification and dust removal, the solution will keep itself clean and free of dust. The fourth electric valve output port 41 serves as the first input port 9 of the filter 24 . The third electric valve output port 38 serves as the second input port 10 of the filter 24 .

The solution flowing into the finned coil tube 21 from the gas-liquid separator 27 is a high-temperature concentrated solution. When the air in the box body 25 flows through the fin coil tube 21 , it exchanges heat with the high-temperature concentrated solution in the fin coil tube 21 . The air warms up and the concentrated solution cools down. The heated air flows out from the air outlet 2 of the casing. The cooled concentrated solution flows to the first electric valve 30 and the second electric valve 33 . By arranging the finned coil tube 21, the reheating of the dehumidified and dust-removed air is realized. At the same time, in this process, the heat of the solution itself is used to heat the air only by adding the finned coil tube 21, which effectively saves energy.
