Usually, an air inlet pipe 1 is fixed at an air inlet of the dust removal box 2, the air inlet pipe 1 is communicated with the outside, and an air suction pump is additionally arranged in the air inlet pipe 1 to play a role in air suction. The dust removal box 2 is fixed outside the closed space, a pipeline is additionally arranged at an air outlet of the dust removal box 2, and the pipeline is communicated with the inside of the closed space, so that the heat dissipation function can be realized.

The cathode filter 3 is preferably fixed at the air inlet of the dust box 2.

After entering the dust removing box 2, the outside air firstly passes through the cathode filter screen 3. The cathode filter screen 3 forms hairiness by spinning conductive fibers, the hairiness is used as an emitter after being woven into a net, and cold-emitted electrons form electron mist. After the outside air passes through the electron fog generated by the cathode filter screen 3, dust in the air and electrons are adsorbed together and are negatively charged. The wall of the anode filter barrel 4 is an anode filter screen which is positively charged, and when the outside air is mixed with negatively charged dust and passes through the anode filter barrel 4, the dust is adsorbed on the anode filter screen. The outside air becomes dustless after passing through the anode filter screen, and is discharged into the closed space from the air outlet of the dust removal box 2, so that the temperature of the closed space is reduced.

In order to prevent the anode filter barrel 4 from being excessively dusty, a dust suction assembly 5 is usually arranged in the barrel to suck dust on the barrel wall. The dust suction assembly 5 is preferably a dust suction nozzle 54, and the dust suction nozzle 54 can be spirally lifted along with the bracket 51 by arranging the screw rod 52 in the anode filter barrel 4 along the axial direction of the barrel body, fixing the bracket 51 on the nut of the screw rod 52, and starting the screw rod 52 after the dust suction nozzle 54 is fixed on the bracket 51, so that dust adsorbed in the anode filter barrel 4 can be sucked completely.

The anode filter screen on the wall of the anode filter barrel 4 is of a double-layer structure, the inner layer of the anode filter screen is a metal power grid, the outer layer of the anode filter screen is a breathable filter screen, and the two layers of structures are tightly attached together. In order to improve the adsorption effect of the dust suction nozzle 54, an elastic member is arranged on the bracket 51 along the radial direction of the anode filter barrel 4, one end of the elastic member is fixed on the bracket 51, and the other end of the elastic member is connected and fixed with the dust suction nozzle 54. Under the elastic action of the elastic part, the dust suction nozzle 54 is always abutted against the anode filter screen, and after the negative pressure device is arranged in the dust suction nozzle 54, the maximum suction force can be ensured during dust suction. The resilient member is preferably a compression spring here.

A dust exhaust pipe 6 is arranged in the dust box 2, a dust suction pipe 53 is arranged on the dust suction nozzle 54, and the dust suction pipe 53 is rotatably connected with the dust exhaust pipe 6. After the dust is sucked by the dust suction nozzle 54, the dust passes through the dust suction pipe 53 and the dust exhaust pipe 6 in order and is discharged to the outside of the closed space. In order to ensure the normal relative rotation between the dust suction pipe 53 and the dust exhaust pipe 6, a bearing bracket is usually fixed in the dust box 2, and a bearing is fixed on the bearing bracket, so that the dust suction pipe 53 and the dust exhaust pipe 6 are connected through the bearing, and the dust exhaust pipe 6 is ensured to be stationary and the dust suction pipe 53 rotates together with the dust suction nozzle 54 in the working process.

The arrangement of the anode filter barrel 4 is only a preferred embodiment, and the anode filter screen with any shape is arranged in the dust removing box 2 for the external air to pass through, and the dust suction assembly 5 with any working mode is arranged for performing dust suction treatment on the anode filter screen. For example, an anode filter screen is fixed at the air outlet of the dust removing box 2, and a strip-shaped dust collector which rotates around the center of the screen surface is arranged on the anode filter screen, so that the function of filtering dust can be realized.

The space between the anode filter barrel 4 and the dust removal box 2 is a dust-free cavity, and after air passing through the anode filter barrel 4 enters the dust-free cavity, the air enters the closed space from the air outlet of the dust removal box 2. In order to balance the pressure intensity in the closed air, a one-way air outlet is arranged in the closed space to discharge air outwards.

The temperature sensor is arranged in the closed space, and transmits a signal to the heat dissipation system after sensing that the temperature in the closed space reaches a set temperature, and the heat dissipation system is started to extract outside air and convey the outside air into the closed space. And closing the heat dissipation system until the temperature in the closed space is reduced to be below the set temperature or the heat dissipation system is started for a specified time.

After air is pumped into the dust removal box 2, the air flow rate is too high, so that when the air passes through the cathode hairiness net 3, part of dust particles in the air pass through an electron fog area generated by the cathode hairiness net 3 without being combined with electrons due to the too high speed, and the part of dust particles cannot be effectively adsorbed by the anode filter barrel 4, so that the adsorption efficiency of the anode filter barrel is reduced. Therefore, a draft tube 7 is additionally arranged between the air inlet of the dust removing box 2 and the cathode hairiness net 3.

After the outside air enters the air duct 71 from the dust removing box 2, the outside air is divided into two flow dividing pipes 72, when the outside air flows out of the two flow dividing pipes 72, the air flow rate is reduced to the maximum extent by the collision of two air flows, and the decelerated air slowly passes through an electron fog area, so that the proportion of combining dust and electrons is improved. The number of the shunt tubes 72 is not limited, and the deceleration function can also be realized by arranging a plurality of shunt tubes to enable a plurality of air strands to collide. The shunt tubes are not arranged right opposite to each other, but an included angle is formed between the shunt tubes, so that air is collided to achieve the effect of speed reduction.

In the actual working process, the closed space needs to be rapidly cooled at some time, and the cooling speed is too low when the cooling system is started to extract air for cooling. Therefore, the air storage box 9 communicated with the dust removal box 2 is arranged in the closed space, the dust removal box 2 conveys the cold air subjected to dust removal in advance into the air storage box 9 for storage, the air storage box 9 is a heat insulation box body, and an air outlet of the air storage box 9 is communicated with the closed space.

An electric push rod 10 is arranged in the driving cavity to drive the partition plate to move, so that the volume of the air storage cavity is changed, and the electric push rod 10 can be replaced by any driving device capable of driving the partition plate to move along. And a ventilation port for balancing pressure intensity is arranged in the driving cavity.

The gas storage tank 9 is also provided with a temperature sensor for sensing the temperature in the closed space, and the gas outlet of the gas storage tank 9 is normally in a closed state. After the temperature in the closed space is sensed to reach the set temperature, the air outlet of the air storage box 9 and the electric push rod 10 are opened, the electric push rod 10 pushes the partition plate to move towards the direction of the air outlet, so that the space of the air storage cavity is compressed, air stored in the air storage box 9 in advance is rapidly sprayed into the closed space, and the effect of rapidly cooling is achieved; then the dust removal case 2 is continuously transported the cold air to the airtight space again and reaches continuous cooling effect.

In order to prevent the air directly discharged from the dust exhaust pipe 6 from being mixed with a large amount of dust to pollute the outside air, a dust storage pipeline 8 is additionally arranged at the air outlet of the dust exhaust pipe. The inner wall of the dust storage line 8 is provided with a suction plate for sucking dust, which is preferably an activated carbon plate 82. In order to facilitate the detachment and fixation of the dust collection plate, the inner wall of the dust storage pipeline 8 is fixed with the air permeable net 81, the pipe wall of the dust storage pipeline 8 is provided with an opening, and the dust collection plate is inserted into the dust storage pipeline 8 from the opening and can be clamped and fixed by the air permeable net 81 and the pipe wall of the dust storage pipeline 8. The air outlet of the dust storage pipeline 8 is positioned outside the closed space, and when air with dust passes through the dust storage pipeline 8, the dust passes through the breathable net 81 and is adsorbed by the dust collection plate, so that the dust content in the air discharged outside the closed space is greatly reduced. After the heat dissipation process is finished, the dust suction plate can be drawn out from the dust storage pipeline 8 in time and replaced.

The inner wall of the dust storage pipeline 8 is also provided with baffle plates 83 in a staggered manner, and the baffle plates 83 are arranged in a staggered manner, so that the gas passing through the dust storage pipeline 8 forms an S-shaped flow track. Due to the increased flow trajectory, the dust adsorption rate is simultaneously increased.
