Description

Air cleaning device and air cleaning method

Technical Field

The invention relates to indoor air treatment equipment, in particular to an air cleaning device. The invention also relates to an air cleaning method.

Background

There are four main types of equipment currently in use for cleaning gas:

1. simple gas washing equipment; and placing the gas outlet below the liquid level, introducing gas into the liquid, and then naturally separating. During the gas-liquid contact period, gaseous impurities capable of chemically reacting with the liquid or gaseous impurities easily soluble in the liquid remain in the liquid, thereby achieving the purpose of cleaning the gas. However, the gas washing equipment has small gas-liquid contact area and short contact time in the working process, so the cleaning efficiency is low, and the equipment is only suitable for occasions with low content of gaseous impurities and low requirement on the cleaning effect.

2. Spraying equipment; dispersing and spraying the liquid by using a spray head, and then driving gas to pass through a liquid dispersion area; during gas-liquid contact, solid and gaseous impurities in the gas may remain in the liquid, serving the purpose of cleaning the gas. The spraying equipment can increase the surface area of liquid so as to increase the contact area of the liquid and the gas, thereby enhancing the cleaning effect on the gas. The spraying equipment can be connected in series or in parallel in multiple stages, has strong processing capacity and is widely applied to industry. However, the spraying equipment needs to be provided with a special water pump, a special spray head, a special water circulating system and the like, the requirement on subsequent maintenance is high, and the volume and the noise are large. Although it can be miniaturized or even miniaturized, the cleaning effect is not good after the volume is reduced, and the noise is difficult to be reduced to a low level due to the water pump, so that the cleaning device is difficult to be used in a household environment.

3. Absorption towers, such as packing towers/buoyant raft towers and other professional gas-liquid exchange equipment, are generally used in the industries such as chemical industry, can effectively clean gas, are large-size professional equipment, can be operated and used by professional personnel, and are difficult to use in a home environment even if the size is reduced.

4. A stirrer; the stirring device for cleaning gas has two types, one is that a mechanical structure (blade/sheet/cylinder, etc.) is utilized to throw liquid, so that the liquid is splashed, and simultaneously, the gas is driven to pass through the splashed liquid, thereby achieving the purpose of cleaning gas; the other is self-excitation type, the liquid level is impacted by utilizing high-speed airflow, the liquid splashes around under the impact of gas, and the gas and the liquid are fully contacted, so that the aim of cleaning the gas is fulfilled. A significant feature of this manner of purging gas is that the liquid is dispersed upon impact, thereby forming a relatively large surface area. However, whether the liquid collides with a mechanical structure or a high-speed airflow, large vibration and noise are generated, and the liquid cannot be used in a home environment for a long time. For example: the water-washing type dust collector has very large noise and vibration during operation and is deaf to shake.

In summary, the currently used gas cleaning devices are not suitable for air cleaning in a domestic environment. Air cleaning in a domestic environment seems to be very simple, but the practical requirements are very demanding: high cleaning efficiency is required, at the same time as a miniaturised volume and extremely low noise, and also easy to use and maintain, although not too costly, and easy to produce and manufacture. These stringent requirements have severely limited the product development of domestic air cleaning devices, and since the industrial revolution, no mature product has been made available to date.

the driving motor 112 drives the fan 113 and the taper pipe assembly 1 to synchronously rotate;

during the rotation process, the fan 113 blows air out of the air outlet F2, and a negative pressure is formed in the space above the water surface of the water tank 101, and the negative pressure causes the outside air to enter the water tank 101 obliquely and downwards along the plurality of arc-shaped channels of the air guide ring 115 through the annular air inlet F1; the airflow formed by negative pressure forms a spiral shape under the combined action of the guide of the arc-shaped channel and the blocking of the inner wall of the water tank 101, and the airflow obliquely flows downwards along the inner wall of the water tank 101 to the inside of the water tank 101 to form a first spiral airflow I1 which rotates to flow downwards;

when water moves upwards from the bottom of the conical pipe 1-1, the centrifugal force generated by the conical pipe 1-1 in the rotating process and the negative pressure act together to drive the airflow around the conical pipe 1-1 to move upwards to form a second spiral airflow I2 flowing upwards in a rotating mode;

The invention can achieve the technical effects that:

according to the invention, by utilizing the rotating action of the conical pipe, on one hand, water moves upwards along the inner wall of the conical pipe and is thrown outwards through the through hole of the conical pipe, and is atomized under the action of the inner wall of the water tank, so that water mist is formed in a gas-liquid mixing space around the conical pipe; on the other hand, the conical tube can form centrifugal force in the rotating process, so that the spiral airflow which originally moves downwards flows upwards; therefore, once the outside air enters the inner cavity of the water tank, the operation is carried out twice, namely the outside air flows downwards in a spiral mode and then flows upwards in a spiral mode; in the process of two times of operation, the water-spraying device is in full contact with a water line and water mist in the gas-liquid mixing space, and in the contact process, the water can fully dissolve and wash small particle impurities in the air; meanwhile, large-particle impurities in the air flow are separated from the air under the action of centrifugal force formed by spiral motion, impact the inner wall of the water tank and enter the water, and therefore air cleaning is achieved.

The conical pipe and the inner wall of the water tank jointly act on water, and the water can be changed into a water line and water mist, so that the surface area of the water body is increased, and the contact area of air and water can be increased from the angle of water.

the air inlet member 114 has an axial extension portion 114-1, and the axial extension portion 114-1 forms a vertical distance W between the upper casing 111 and the air guide ring 115, so that an annular air inlet F1 is formed between the upper casing 111 and the air guide ring 115;

the diameter of the axial extension 114-1 of the air intake member 114 is smaller than the diameter of the water tank 101 so that the air intake F1 is located above the edge of the water tank 101, thereby allowing air to enter the edge of the water tank 101 from above;

according to the invention, the annular air inlet F1 is formed between the upper shell 111 and the air guide ring 115, and the negative pressure generated by the rotation of the fan 113 can enable air near the air inlet F1 to be sucked from the periphery, so that the air around the machine can be cleaned simultaneously, and therefore, the treatment capacity of the invention in unit time is larger.

As shown in fig. 9, the air guide ring 115 comprises an inner ring 115-1 and an outer ring 115-2, the inner ring 115-1 is arranged inside the outer ring 115-2, an annular cavity is formed between the inner ring 115-1 and the outer ring 115-2, a plurality of arc-shaped blades 115-3 are circumferentially distributed in the annular cavity, and each blade 115-3 circumferentially extends from the top of the annular cavity to the bottom of the annular cavity, so that the annular cavity is divided into a plurality of arc-shaped channels, and the arc-shaped channels circumferentially extend from the top of the air guide ring 115 to the bottom of the air guide ring 115; the inlet of the arc-shaped channel faces to an annular air inlet F1 positioned at the top of the air guide ring 115, and the outlet of the arc-shaped channel faces to the inner wall of the water tank 101 positioned at the bottom of the air guide ring 115;

the air inlet is arranged above the water tank 101, so that air sucked from the side part of the machine body has a downward movement tendency; meanwhile, the air guide ring 115 is arranged below the air inlet, an arc-shaped channel formed between adjacent arc-shaped blades 115-3 of the air guide ring 115 extends from the top of the air guide ring 115 to the bottom of the air guide ring 115 along the circumferential direction, and the arc-shaped channel can guide the air above the air guide ring 115 (namely the air inlet) to enable the air to flow into the water tank 101 obliquely downwards along the inner wall of the water tank 101, so that the air sucked from the side part of the machine body flows into the water tank 101 downwards in a spiral shape, and a first spiral air flow which flows in a rotary direction downwards is formed at the upper part of the water tank 101.

The top of the outer ring 115-2 is provided with an overlapping ring 115-21, the diameter of the overlapping ring 115-21 is larger than that of the water tank 101, the outer ring 115-2 of the air guide ring 115 can be overlapped on the top of the water tank 101 through the overlapping ring 115-21, and the machine body can be suspended in the water tank 101.

The air cleaning method comprises the following steps:

starting the driving motor 112, and driving the fan 113 and the taper pipe assembly 1 to synchronously rotate by the driving motor 112;

during the rotation process of the fan 113, the air is blown out from the air outlet F2, so as to form a negative pressure in the space above the water surface of the water tank 101, and the negative pressure causes the outside air to enter the water tank 101 from top to bottom through the lateral air inlet F1 along the plurality of arc-shaped channels of the air guide ring 115; because the arc-shaped channel extends from the top of the air guide ring 115 to the bottom of the air guide ring 115 along the circumferential direction, the air flow formed by negative pressure forms a spiral air flow under the combined action of the guidance of the arc-shaped channel and the blockage of the inner wall of the water tank 101, and the spiral air flow obliquely flows downwards along the inner wall of the water tank 101 to the inside of the water tank 101; the spiral airflow is used as a first spiral airflow I1, and the first spiral airflow I1 rotates and flows downwards in the water tank 101;

meanwhile, the conical pipe 1-1 of the conical pipe assembly 1 sucks water in the water tank 101 from a water inlet at the bottom into an inner cavity of the conical pipe assembly in the rotating process; the water moves upwards along the conical pipe 1-1 to the spraying area and is thrown outwards through the through hole in the side wall of the conical pipe 1-1, and a dense annular column waterline is formed in the spraying area; the water line thrown out from the conical pipe 1-1 impacts the inner wall of the injection area, the small water column is smashed by the reaction force of the inner wall of the water tank 101, a water mist layer is formed on the inner wall of the water tank 101, and the water mist flows downwards along the inner wall of the water tank 101 under the dual action of centrifugal force and gravity and is converged with the water body in the water tank 101 to realize water circulation, as shown in fig. 5;

when water moves upwards from the bottom of the conical pipe 1-1, the centrifugal force generated by the conical pipe 1-1 in the rotating process and the negative pressure act together to drive the airflow around the conical pipe 1-1 to move upwards to form a second spiral airflow I2; the second spiral air flow I2 rotates and flows upwards in the water tank 101, passes through the space between the supporting arms 2-7, enters the fan 113, and is finally discharged from the air outlet F2, as shown in fig. 6 to 8;

the first spiral airflow I1 penetrates through the spraying area from top to bottom, the second spiral airflow I2 penetrates through the spraying area from bottom to top, the airflows are fully contacted with a water line and water mist in the process of penetrating through the spraying area twice, and impurities in the airflows are settled down by the water, so that the air is cleaned; simultaneously, the air current is at the in-process that jet zone and waterline and water smoke contacted, and partly aquatic can evaporate to can increase the humidity of air.

The diameter of the first spiral air flow I1 is determined by the diameter of the water tank 101, the diameter of the second spiral air flow I2 is determined by the diameter of the conical tube 1-1, and obviously, the second spiral air flow I2 is positioned inside the first spiral air flow I1, so that the two air flows do not interfere with each other, as shown in FIGS. 7 and 8; it should be noted that fig. 7 is a diagram of the air Flow motion trajectory simulated by the structure according to the present invention, which is automatically generated by SOLIDWORKS Flow simulation (fluid analysis) software; FIG. 8 is a simplified schematic illustration of the gas flow trajectory of FIG. 7;

according to the invention, by utilizing the synergistic effect of the air guide ring 115 and the conical pipe 1-1, after outside air enters the spraying area at the upper part of the water tank 101, a first spiral air flow flowing downwards is formed at the inner wall of the water tank below the air guide ring 115, then a second spiral air flow flowing upwards is formed around the conical pipe 1-1, the first spiral air flow and the second spiral air flow repeatedly contact with water thrown out from the spraying area of the conical pipe 1-1 in the flowing process, and impurities in the air are fully dissolved into the water in the contacting process, so that the air is cleaned.

The running path of the air current in the water tank firstly rotates to flow downwards as a first spiral air current and then rotates to flow upwards as a second spiral air current, and the running path is long enough and has sufficient time to be in contact with a water line and water mist, so that the cleaning effect is obvious.

The invention realizes the cleaning of air by utilizing the full contact of air flow and water, and the cleaning method does not need any consumable materials such as activated carbon and the like, but takes the water as the consumable material. Once the water as a consumable is contaminated by impurities in the air, the water is simply replaced. The invention thoroughly gets rid of the dependence of air cleaning equipment on consumables.

The water mist generated in the working process of the invention only exists in the spraying area of the water tank 101, the water mist flows downwards to return into the water tank 101 under the dual action of centrifugal force and gravity, and the second spiral air flow can be discharged from the air outlet F2 only by passing through the fan 113 above, therefore, the invention can realize automatic demisting, and the water mist visible to naked eyes can not appear at the air outlet F2.

The upper part of the water tank 101 is used as an injection area E2, after water passes through the through hole on the side wall of the conical pipe 1-1 and is thrown outwards, the inner wall of the water tank 101 can generate blocking force on the water, so that the water flows downwards along the inner wall of the water tank 101; meanwhile, the inner wall of the water tank 101 and the plurality of arc-shaped channels of the air guide ring 115 work together, and when outside air enters the water tank 101 from the air inlet F1, the air flow moves along the inner wall of the upper part of the water tank 101 under the guiding action of the arc-shaped channels, so that the moving path of the air flow is spiral to form a first spiral air flow. Therefore, the water tank 101 of the present invention is not only used for storing water, but also can guide the movement track of the air flow together with the air guide ring 115, and at the same time can generate a blocking force for the water flow sprayed from the tapered pipe 1-1, so that the air can be fully contacted with the water, thereby realizing the cleaning of the air.

Due to the powerful cleaning effect of the present invention on air, water in the water tank 101 may enter impurities during use. In order to facilitate the cleaning of the water tank 101 and the replacement of water, as a preferred embodiment, the base bracket 5 for positioning the lower end of the conical pipe 1-1 and the air inlet member 114 may be fixedly connected into a whole by a plurality of connecting rods 104 distributed along the circumferential direction; specifically, the upper end of the connecting rod 104 is fixedly connected to the bottom of the air inlet member 114, and the lower end of the connecting rod 104 is fixedly connected to the outer edge of the base bracket 5; thereby enabling the cone assembly 1 to be removed from the tank 101 together with the connection at its lower end.

In addition, in order to avoid the water outlet 1-11 of the conical pipe 1-1 from being blocked by impurities in water, as a preferred embodiment, a filter screen can be arranged below the water inlet of the conical pipe 1-1; specifically, the filter screen may be fixedly disposed below a wing plate of the base bracket 5; at this time, the base 103 may be disposed below the base support 5, and the taper pipe housing 102 may be disposed above the base support 5; the taper pipe outer cover 102 and the base 103 are fixedly connected through bolts, so that the base bracket 5 and a filter screen below the base bracket are wrapped in the base bracket;

the taper pipe outer cover 102 is fixedly connected with the air inlet part 114 into a whole through the connecting rod 104; specifically, the upper end of the connecting rod 104 is fixedly connected with the bottom of the air inlet part 114, and the lower end of the connecting rod 104 is fixedly connected with the taper pipe outer cover 102;

the taper pipe outer cover 102 and the air inlet part 114 of the hanging taper pipe assembly 1 are fixedly connected into a whole through the connecting rod 104, the lower shaft 1-5 of the taper pipe assembly 1 is positioned in the base support 5, and the taper pipe outer cover 102 is fixedly connected with the base support 5 through the base 103, so that the taper pipe assembly 1, the base support 5 positioned at the lower part and the air inlet part 114 positioned at the upper part are integrated into a machine body, as shown in figure 3, the lower part of the machine body extends out of the water tank 101 during use, the machine body positioned at the upper part can be taken out of the water tank 101 during cleaning, impurities generated in the cleaning process can be deposited at the bottom of the water tank 101, and therefore, the cleaning and the replacement of the water tank 101 are very convenient.

The connecting rod 104 of the present invention is used as a connecting piece between injection-molded parts (the air intake part 114 and the taper pipe outer cover 102 are both injection-molded parts), and the material of the connecting rod is a metal or metal coating layer to ensure the firmness of the connection. Preferably, the material of the connecting rod 104 may be silver or copper, or silver or copper as a coating, or an alloy containing silver or copper, so that the connecting rod 104 has a natural sterilization effect.

The inner diameter of the cover cylinder of the taper pipe cover 102 is larger than the outer diameter of the taper pipe 1-1, and an annular gap is formed between the cover cylinder of the taper pipe cover 102 and the taper pipe 1-1, so that the taper pipe 1-1 can freely rotate in the taper pipe cover 102;

as a preferred embodiment, the height of the cone housing 102 is smaller than the height of the cone 1-1; the height of the cover cylinder of the taper pipe cover 102 determines the height of the highest water level line H in the water tank 101; the water tank 101 is divided into an injection area E2 and a water storage area E1 by the cover cylinder of the taper pipe outer cover 102, wherein the bottom of the water storage area E1 is used as a sedimentation area;

when the water tank is used, the water level in the water tank 101 is lower than the upper edge of the cover cylinder of the taper pipe outer cover 102, and the cover cylinder of the taper pipe outer cover 102 can prevent water from entering the tapered pipe 1-1 from the upper part of the filter screen, so that the water can only enter the inner cavity of the tapered pipe 1-1 from the water inlet at the bottom; thus, the cone housing 102 can function to direct the direction of the water flow.

In the working process of the invention, the conical pipe 1-1 and the fan 113 are driven by the same motor, and in order to ensure that the conical pipe 1-1 and the fan 113 synchronously and stably rotate, the conical pipe 1-1 and the fan 113 are required to be ensured to be positioned on the same axis, if the coaxiality of the conical pipe 1-1 and the fan 113 does not meet the specification, the conical pipe 1-1 or the fan 113 can swing, so that the vibration of the machine exceeds the standard in the running process, and finally the machine cannot normally run. However, in order to reduce the manufacturing cost, the tapered tube 1-1 and the fan 113 of the present invention are injection molded parts, which have a lower precision than machined parts, so that the coaxiality of the tapered tube 1-1 and the fan 113 is hardly specified. If a precise coupling is used to achieve the coaxial connection between the tapered tube 1-1 and the fan 113, this will result in an increase in the cost of the machine. Therefore, the fan 113 is fixedly connected with the motor output shaft 3, the motor output shaft 3 is fixedly connected with the upper shaft 1-3 of the taper pipe assembly 1 through the elastic coupling part 2-2, and the coaxiality between the upper shaft 1-3 and the lower shaft 1-5 of the taper pipe assembly 1 is finely adjusted through the aligning function of the bearing sleeve 2-5 and the positioning ring 4-1, so that the coaxial connection between the taper pipe 1-1 and the fan 113 can be realized at low cost even if the manufacturing precision of the taper pipe 1-1 and the fan 113 is low.

The airflow path formed by the present invention is formed by the combined action of the fan 113, the wind guide ring 115 and the rotation of the cone assembly 1, so the rotating speed of the fan 113 does not need to be too high, generally 1000-1500 rpm, and the requirement of air cleaning can be met.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention. Thus, it is intended that the present invention cover the modifications and variations of this invention provided they come within the scope of the appended claims and their equivalents.
