The lower part of the body 2 is provided with a dust collecting device 6 for collecting dust scattered on the surface of the filter 4; the dust collecting device 6 includes a dust storage hopper 61 that can be pulled out of the body 2; the upper part of the dust collecting device 6 is provided with an air inlet cavity 24; the air inlet 21 is located on the side wall of the air inlet cavity 24; and the air inlet cavity 24 is provided with a dust removal device 3 for removing dust from the filter 4. The dust collecting device arranged at the lower part of the body cooperates with the dust removal device for removing dust from the filter, and the dust remaining on the filter in the airflow is automatically cleaned, and the dust is automatically scattered to the dust collecting device at the lower part, so that the dust is quickly and automatically collected, the continuous use of the equipment is ensured, and the workload of the staff for cleaning the filter is reduced.

[0022] Specifically, a horizontally arranged air plate 25 is provided in the air inlet cavity 24; a plurality of air ports 26 for air flow to communicate with the air outlet 22 are provided on the air port 25; the filter 4 includes a plurality of cylindrical filter screens 41 whose inner cylinders are connected to the air ports 26; the cylindrical filter screens 41 surround the air ports 26 and the upper end is provided on the air port 25. By designing the air ports for air flow to pass through, the vertical cylindrical filter screens fully filter the air flow passing through the air inlet, thereby achieving full filtration of the air flow.

[0023] Specifically, the dust removal device 3 includes a plurality of pulse nozzles 31 with pulse valves facing the inner cylinder of the cylindrical filter 41, and an air storage tank 32 connected to the plurality of pulse nozzles 31. By designing a dust removal device for pulse jetting to the filter, the high-pressure airflow is quickly ejected to impact and vibrate the cylindrical filter, and the filter is quickly dusted without affecting the upward circulation of the airflow, thereby ensuring the uninterrupted operation of the equipment.

[0024] Specifically, the heat exchanger 1 is tilted in the heat exchange cavity 27 above the air inlet cavity 24 ; a water receiving tank 11 connected to the outside of the body 2 through a pipeline is provided at the bottom of the heat exchanger 1 ; the heat exchanger 1 is tilted upward in a direction away from the water receiving tank 11 .

[0025] Specifically, the angle between the heat exchanger 1 and the horizontal direction is 65°~75°.

[0026] Specifically, the air inlet 21 is provided with a louver 221 that can be opened and closed; the louver 221 is provided with multiple groups of air inlets 222; each group of air inlets 222 includes an upper louver 223 that guides air upwards and a lower louver 224 that guides air downwards; the upper louver 223 is located above the lower louver 224; the angles between the upper louver 223 and the horizontal direction are 120°~140°; the angles between the lower louver 224 and the horizontal direction are 120°~140°. The upper louver set at an angle cooperates with the lower louver to form a staggered guidance of the airflow, ensuring a sufficient wind passing area, while ensuring the strength of the air inlet and reducing the risk of deformation.

[0027] Specifically, the dust hopper 61 is provided with a guide plate 62 for guiding dust into its inner cavity; the dust hopper 61 includes a plurality of dust collection drawers 63 matching the cylindrical filter screen 41; the dust collection drawers 63 are arranged at intervals and can be independently pulled out of the machine body 2.

[0028] Specifically, rubber-plastic thermal insulation cotton is arranged on the inner wall of the machine body 2 .

[0029] Specifically, rubber-plastic heat-insulating cotton is provided on the outer wall of the water receiving tank 11 .

[0030] The external compressed air source passes through the gas-liquid separator and then enters the air storage tank 11 as a dry air flow.

[0031] Working principle: The staff installs the air conditioner at the preset position. After the equipment is started, the centrifugal fan 23 drives the air flow from the air inlet 21 into the body 2. The air flow passes through the air inlet 21 formed by multiple upper louvers 223 and lower louvers 224, and enters the air inlet cavity 24 to form a staggered air flow. After being filtered by the vertical cylindrical filter 41, it flows upward from the inner cylinder of the cylindrical filter 41 through the air outlet 26. After heat exchange through the inclined heat exchanger 1 connected to the external cold source or heat source, it is discharged from the air outlet 22 on the upper part of the body 2. A water receiving tank 11 is provided at the lower part of the heat exchanger 1. The water droplets condensed on the outer wall of the heat exchanger 1 are gathered and guided into the water receiving tank 11, and discharged from the body through the pre-connected pipeline. 2. The gas storage tank 32 is connected to the gas compressor through an external gas-liquid separator, and dry gas is filled into the gas storage tank 32. After a period of use, the pulse valve is started by the controller at a fixed time, and the high-pressure airflow in the gas storage tank 32 is quickly ejected and released from the pulse nozzle 31 to the inner tube of the cylindrical filter 41. The quickly released compressed gas impacts the cylindrical filter 41, and the dust on the surface of the cylindrical filter 41 is shaken and scattered, and is collected in the dust storage hopper 61 at the bottom. After a period of time, the staff can pull out the multiple dust collection drawers 63 at the bottom of the body 2, and quickly collect and organize the dust filtered by the filter 4, so as to ensure the continuous use of the equipment and reduce the labor intensity of the staff.

Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
