[0056] Referring to Fig. 1, an exemplary energy-saving air purification system for a factory building according to the present application includes a cold-drying cylinder 10, a filter cylinder 20, a circulating pump (not shown), a refrigeration assembly 30, a connecting hose (not shown), an inlet hose (not shown), and an outlet hose (not shown); Figures 1-8 The cold-drying cylinder 10 includes a first cylinder body 11, an air inlet pipe 12, a transverse partition plate 14, a drainage guide 15, and a first connecting pipe 13.

[0057]

[0058] ​​The first cylinder 11 is vertically placed, the transverse partition plate 14 is installed at the bottom of the first cylinder 11, and the transverse partition plate 14 is transversely placed; a plurality of through holes A are formed in the transverse partition plate 14;

[0059] The air inlet pipe 12 is vertically placed and sequentially penetrates the top surface of the first cylinder 11 and the transverse partition plate 14;

[0060] The water drainage guide pipe 15 is installed at the bottom end of the first cylinder 11;

[0061] The first connecting pipe is installed at the upper portion of the first cylinder 11 and is connected with the filter cylinder 20;

[0062] The refrigeration pipe line 33 of the refrigeration assembly 30 penetrates the first cylinder 11 and is spirally wound on the air inlet pipe 12;

[0063] The filter cylinder 20 is connected with the inlet end of the circulating pump through the connecting hose, and the outlet end of the circulating pump is connected with one end of the outlet hose;

[0064] The top end of the air inlet pipe 12 is connected with one end of the inlet hose;

[0065] The other end of the inlet hose and the other end of the outlet hose are respectively used for communication with the factory building.

[0066] The energy-saving air purification system for a factory building of the present application purifies most of the water vapor and impurities in the air through condensation and drying of the cold-drying cylinder 10, filters the air through the filter cylinder 20, and finally returns the clean air to the factory building through the outlet hose. After this cycle, the air in the factory building is purified. In the whole air circulation process, the circulating pump is used as a power source.

[0067] In some preferred embodiments, the filter cylinder 20 comprises a second cylinder 21, a vertical partition plate 25, a second connecting pipe 22, an air outlet pipe 23, a filter assembly 24, and a blowdown pipe 26;

[0068] The second connecting pipe 22 and the air outlet pipe 23 are respectively installed at the two sides of the upper portion of the second cylinder 21;

[0069] The filter assembly 24 is installed in the second connecting pipe 22, and the second connecting pipe 22 is connected with the first connecting pipe 13;

[0070] The vertical partition plate 25 is vertically placed in the second cylinder 21, and the second connecting pipe 22 and the air outlet pipe 23 are respectively located at the two sides of the vertical partition plate 25;

[0071] The vertical partition plate 25 is arranged in the middle upper part of the second cylinder 21 and separates the inner cavity of the second cylinder 21 into two communicating chambers.

[0072] The drain pipe 26 is arranged at the bottom end of the second cylinder 21.

[0073] The air outlet pipe 23 is connected with the circulating pump through the connecting hose.

[0074] In the present application, the filter cylinder 20 is not only provided with the filter assembly 24 but also provided with the vertical partition plate 25. On one hand, the vertical partition plate 25 filters the air. On the other hand, when the filtered air impacts on the vertical partition plate 25, dust and water droplets are gathered and then fall along the wall surface of the vertical partition plate, thereby further purifying the air.

[0075] The filter assembly 24 of the present application can be any structure form in the prior art.

[0076] The steam-water separator is arranged on the drain pipe at the bottom of the filter cylinder 20, thereby automatically draining water.

[0077] In some preferred embodiments, the inner diameters of the first connecting pipe 13, the second connecting pipe 22 and the air outlet pipe 23 are respectively greater than the inner diameter of the air inlet pipe 12.

[0078] The ratio of the inner diameter of the first cylinder 11 to the inner diameter of the air inlet pipe 12 is 20:1-5:1.

[0079] In other preferred embodiments, the inner diameters of the first connecting pipe 13, the second connecting pipe 22 and the air outlet pipe 23 are the same.

[0080] Since the inner diameter of the first connecting pipe 13 is greater than the inner diameter of the air inlet pipe 12, air is more easily flowed out of the first cylinder 11 than flowed into the first cylinder 11, thereby reducing the pressure loss of the flow through the first cylinder.

[0081] In some preferred embodiments, the refrigeration assembly 30 comprises a compressor, a condenser 31, a liquid storage tank 32, an expansion valve and a refrigeration pipeline 33.

[0082] The refrigeration pipeline 33 is sequentially connected with the compressor, the condenser 31, the liquid storage tank 32, the expansion valve and the air inlet pipe 12 and forms a circulating loop.

[0083] The compressor is used for pressurizing refrigerant.

[0084] The condenser 31 is used for cooling the increased refrigerant.

[0085] The liquid storage tank 32 is used for storing liquid-phase refrigerant in the circulating loop.

[0086] The expansion valve is used to depressurize the refrigerant to generate low-temperature refrigerant;

[0087] The outer wall of the portion of the air inlet pipe 12 located inside the first cylinder 11 is spirally wound with the refrigeration pipe 33 for cooling the air inlet by low-temperature refrigerant.

[0088] In this application, the refrigeration assembly 30 mainly plays a role in providing cold energy to promote the cooling and impurity removal of the air in the first cylinder 11.

[0089] In some preferred embodiments, the inner diameter of the first cylinder 11 is greater than the inner diameter of the second cylinder 21. When the inner diameter of the first cylinder 11 is greater than the inner diameter of the second cylinder 21, it can be more energy-efficient, and the cooling effect of the air in the first cylinder is better.

[0090] In some preferred embodiments, a base 40, a first support rod 51, and a second support rod 52 are further included.

[0091] The bottom of the first cylinder 11 is fixedly installed on the base 40 by a plurality of first support rods 51.

[0092] The bottom of the second cylinder 21 is fixedly installed on the base 40 by a plurality of second support rods 52.

[0093] In some preferred embodiments, the refrigeration pipe 33 spirally wound around the air inlet pipe 12 has an air inlet end located at the bottom of the air inlet pipe 12 and an air outlet end located at the upper portion of the air inlet pipe 12.

[0094] In this application, the refrigeration pipe 33 is wound around the air inlet pipe 12, thereby transferring cold energy to the air inlet pipe 12, and then cooling the air inlet; at the same time, the cold energy is also transferred to the air in the first cylinder 11, and the air is cooled for the first time when it enters the air inlet pipe 12; then the air rises from the bottom of the first cylinder 11, and the space between the air inlet pipe and the first cylinder is cooled for the second time.

[0095] In some preferred embodiments, the first connecting pipe 13 and the second connecting pipe 22 are connected by flanges.

[0096] The inner diameters of the air inlet pipe 12 and the air outlet pipe 23 are equal.

[0097] In some preferred embodiments, an automatic water drainage valve is installed on each of the drainage guide 15 and the sewage pipe 26. The automatic water drainage valve mentioned here can be a steam-water separator.

[0098] In some preferred embodiments, the total cross-sectional area of the plurality of through holes A is greater than the cross-sectional area of the air inlet pipe 12.

[0099] The application realizes the combination of two functions, the first is the refrigeration function, and the second is the air purification function, and the two functions are realized by a set of system connection, which is inseparable, and the technical effects brought by this include not only energy saving, but also better purification and refrigeration effects.

[0100] The traditional air refrigeration and purification are two independent links, and the essence device can be arranged in the refrigeration circulating device, but the technical scheme of the application is more optimal, because the first cylinder 11 for refrigeration adopted by the application has a large enough inner cavity, so that the pressure loss is small, and the air flow speed is fast enough; secondly, in the air inlet precooling process, the cooling effect is good enough, and the process of continuous cooling is realized, and then the condensed water droplets are discharged from the bottom end of the first cylinder 11, and in the process of cooling air, the impurities in the air are also taken away, realizing the first air purification.

[0101] Then, when entering the second cylinder 21, the air is purified and filtered once, and then the air flow in the second cylinder 21 first goes down and then rises, realizing water condensation and discharge from the bottom end of the cylinder again, and finally the air entering the circulating pump is clean enough and low enough in temperature, and the cooled air returns to the factory building, realizing the air circulation.

[0102] In order to ensure the good air circulation effect in the factory building, the inlet hose is connected to the bottom of the factory building, and the outlet hose is connected to the upper part or the top of the factory building.

[0103] The above-described embodiments only express several embodiments of the application, and the description is more specific and detailed, but it cannot be understood as a limitation on the scope of the application. It should be pointed out that for ordinary skilled in the art, without departing from the concept of the application, a number of modifications and improvements can be made, which belong to the protection scope of the application.
