Description

Technical Field

[0001] This application relates to the technical field of gas cleaning, and more particularly to a gas jet dust removal device and its dust removal system. Background Technology

[0002] Currently, water film dust collectors are widely used in the dust removal field due to their simple structure, stable operation, and convenient maintenance. Their principle is that the dust-laden airflow enters the dust collector tangentially, forming a high-speed rotating airflow. The dust in the airflow is thrown against the inner wall of the dust collector by centrifugal force and is adsorbed and carried away by the downward-flowing water film, thus achieving the dust removal effect. However, because the water film flows from top to bottom, when the airflow comes into contact with the water film, the water film is immediately blown away by the airflow. The water film cannot enter the center of the airflow; only the outer edge of the airflow can contact the water film, while the center of the airflow basically cannot reach the water film. Therefore, the dust removal effect is greatly affected.

[0003] Patent publication number CN204395710U discloses a cyclone water film dust collector. In this document, several water-following slits are evenly distributed around the junction of the top wall of the volute-type air intake channel and the inner wall of the hollow cylinder, as well as around the junction with the outer wall of the exhaust pipe. This allows water to diffuse downwards along the wall, forming water strips along the slits. However, this technical solution only makes the water film formation on the inner wall more uniform; it still does not solve the problem of the water film not contacting the center of the airflow.

[0004] Patent publication number CN105833628B discloses a microporous plate type water film dust collector. In this publication, although a first-stage microporous plate and a second-stage microporous plate are set in the inner cavity, the micropores are only used as ventilation holes. The purpose is to make the airflow contact with the water film more fully, but it still cannot solve the problem that the center of the airflow cannot contact the water film. Utility Model Content

[0005] To address the problems of existing technologies, this application proposes a gas jet dust removal device and system. The device comprises a jetting body for supplying airflow, with a jetting surface. Airflow is continuously injected into and flows over this surface, while water is also continuously injected into and flows over the jetting surface. When the airflow and water flow converge, dust particles in the gas are captured in the water flow, thus achieving gas dust removal. Compared to existing technologies, this application proposes a gas jet dust removal device and system where, when the airflow flows along the jetting surface, both the edges and center of the airflow can form sufficient contact with the water film (or water mist), ensuring that dust particles are adsorbed and carried away by the water flow, further improving the dust removal effect and effectively solving the problems of existing technologies.

[0013] The airflow and the water flow are sprayed onto the inlet plane at a small angle and form an air film and a water film respectively, flowing forward. After smoothly flowing into the inner arc surface, they rotate centrifugally. After running a certain distance, due to the decrease in speed, the water containing dust particles flows downward along the inner arc surface under the action of its own gravity.

It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a system, product, or device that comprises a series of units, modules, or components is not necessarily limited to those explicitly listed, but may include other components not explicitly listed or inherent to such systems, products, or devices.

[0054] The technical solution of this application will be further described below with reference to the accompanying drawings and specific embodiments.

[0055] Figure 1 , Figure 2 This is a schematic diagram of the structure of the first embodiment of this application. The figure shows that, in this example, a gas jet dust removal device includes:

[0056] A jetting body 1 for supplying airflow, the jetting body having a jetting surface 1A;

[0057] The gas is connected to the airflow nozzle 2 of the jet device, which delivers the gas that needs to be dusted to the airflow nozzle 2 and ejects it from the airflow injection port 2.1;

[0058] A water nozzle 3 is connected to a water spraying device, which delivers water to the water nozzle 3 and sprays it out from the water spray port 3.1;

[0059] Preferably, in this example, the blowing body 1 is a thin arc-shaped body (a thin rectangular prism bent into an arc-shaped structure), and the blowing surface 1A is the inner arc surface of the arc-shaped body.

[0060] Preferably, in this example, the spray surface 1A also has an inlet plane 1B at the inlet, which is tangent to the spray surface 1A. The airflow nozzle 2 and the airflow nozzle 3 spray airflow and water onto the inlet plane 1B, one in front of the other. The purpose of the inlet plane 1B being tangent to the spray surface 1A is to ensure that the injected airflow and water flow smoothly into the spray surface 1B and then rotate centrifugally.

[0061] Preferably, in this example, the spray port 2.1 of the airflow nozzle 2 has a flat structure, and the spray port 3.1 of the water flow nozzle 3 has a flat structure.

[0062] Preferably, in this example, the airflow and water flow are injected onto the inlet plane 1B at a small injection angle (the injection angle being the angle formed between the direction of the airflow and water flow and the inlet plane) and form air films and water films respectively, flowing forward. Afterward, they flow tangentially into the inner arc surface and then rotate centrifugally along the inner arc surface. Preferably, the injection angle is 0-30°. The selection of the injection angle should ensure that the airflow and water flow can form air films and water films respectively after being injected onto the inlet plane 1B and flow forward.

[0063] In this example, the airflow is ejected from the nozzle 2.1 of the airflow nozzle 2 connected to the jet device, and the water flow is ejected from the nozzle 3.1 of the water flow nozzle 3 connected to the water spray device. The airflow and water flow are ejected one after the other onto the inlet plane 1B, and then converge together to rotate centrifugally along the inner arc surface. Dust particles in the gas are captured in the water flow. Under the action of centrifugal force, the dust particles and water film adhere tightly to the inner arc surface and rotate centrifugally. After running a certain distance, due to the decrease in speed, the water containing dust particles flows downward along the inner arc surface under the action of its own gravity, while the dust-removed, water-insoluble gas will be dispersed to the vicinity, thereby achieving dust removal of the gas.

[0064] Figure 3 , Figure 4 This is a schematic diagram of the structure of the second embodiment of this application. The figure shows that, in this example, a gas jet dust removal device includes:

[0065] A jetting body 1 for supplying airflow has a jetting surface 1A.

[0066] The gas is connected to the airflow nozzle 2 of the jet device, and the jet device delivers the gas that needs to be dusted to the airflow nozzle 2 and ejects it from the airflow injection port 2.1;

[0067] Multiple water mist nozzles 3A are connected to the water spraying device, and the water spraying device delivers water to the water mist nozzles 3A and sprays it out from the water mist nozzles.

[0068] Figure 3 and Figure 4 As shown, multiple water mist nozzles 3A are mounted around the airflow nozzle 2's airflow injection port 2.1 (similar to a mist cannon for spraying humidification). In this example, the water mist nozzles 3A are mounted and fixed around the airflow nozzle's injection port. This application suggests that in other embodiments, the water mist nozzles may also be mounted and fixed on the spray body and positioned close to the airflow injection port 2.1.

[0069] In this example, the airflow nozzle is installed and fixed at the inlet of the spray surface 1A. The airflow ejected from the airflow nozzle 2 combines with the water mist ejected from multiple water mist nozzles 3A to form an aerosol. The aerosol is sprayed into the spray surface 1A to form an aerosol film and flows closely to the spray surface. Dust particles in the gas are captured in the water flow, thereby realizing the gas dust removal function.

[0070] Preferably, in this example, the blowing body 1 is a thin arc-shaped body, and the blowing surface 1A is the inner arc surface of the arc-shaped body;

[0071] The blowing surface 1A also has an inlet plane 1B at the inlet, which is tangent to the blowing surface 1A. The airflow nozzle 2 sprays the aerosol onto the inlet plane 1B.

[0072] The aerosol is sprayed onto the inlet plane 1B at a small angle of entry and forms an aerosol film that flows forward. After flowing smoothly into the inner arc surface, it rotates centrifugally. After running a certain distance, due to the decrease in speed, the water containing dust particles flows downward along the inner arc surface under its own gravity, while the water-insoluble gas after dust removal will be dispersed to the vicinity, thereby achieving dust removal of the gas.

[0074] A blower body 1 for supplying airflow has a blower surface 1A.

[0075] The gas is connected to the airflow nozzle 2 of the jet device, and the jet device delivers the gas that needs to be dusted to the airflow nozzle 2 and ejects it from the airflow injection port 2.1;

[0076] The tiny water outlets 3B are connected to the water spraying device and are densely arranged at the inlet of the spraying surface 1A.

[0077] The airflow nozzle 2 is installed and fixed at the inlet of the spray surface 1A. After the airflow is injected into the spray surface 1A, it forms an air film and flows closely against the spray surface. During the flow, it merges with the water flow sprayed (or overflowed) from the tiny water outlet 3B. Dust particles in the gas are captured in the water flow, thereby achieving gas dust removal.

[0078] Preferably, in this example, the spray body 1 is a thin arc-shaped body, and the spray surface 1A is the inner arc surface of the arc-shaped body; the back of the arc-shaped body at the airflow inlet is also fitted with a water storage cavity 3B1 connected to the water spraying device, and each tiny water outlet 3B is independently connected to the water storage cavity 3B1.

[0079] The blowing surface 1A also has an inlet plane 1B at the inlet, which is tangent to the blowing surface 1A. The airflow nozzle 2 sprays airflow onto the inlet plane.

[0080] The airflow is sprayed onto the inlet plane 1B at a small angle of entry and forms air films. During the flow, it merges with water and flows smoothly into the inner arc surface. After running for a certain distance, due to the decrease in speed, the water containing dust particles flows downward along the inner arc surface under its own gravity.

[0081] Figure 7 , Figure 8 This is a schematic diagram of the structure of the fourth embodiment of this application. The figure shows that, in this example, a gas dust removal system includes: the gas jet dust removal device of the above embodiments;

[0082] It also includes an air jet device connected to the air jet nozzle 2. The air jet device mainly includes a fan and an air duct. Under the action of the fan, the gas that needs to be dusted is transported to the air jet nozzle 2 through the air duct and sprayed out from the air jet port 2.1.

[0083] It also includes a water spraying device 4 connected to the water nozzle 3. The water spraying device 4 mainly includes a water tank 4.1 that can add water and drain water, a water pump 4.2 and a water pipe 4.3. Water 4.4 is stored in the water tank 4.1. Under the action of the water pump 4.2, the water 4.4 in the water tank 4.1 is transported to the water nozzle 3 through the water pipe 4.3 and then sprayed out from the water spray port 3.1.

[0084] In this example, preferably, the blowing body 1 is a thin, arc-shaped body, the blowing surface 1A is the inner arc surface of the arc-shaped body, and the water tank 4.1 has a barrel-shaped structure. The blowing body 1 is installed on the opening of the water tank 4.1 and forms an integral structure with the barrel body of the water tank 4.1 (which can be manufactured by injection molding). Water containing dust particles flows downward along the inner arc surface under its own gravity and eventually collects in the barrel cavity of the water tank 4.1 for recycling. In this example, the gas is freely released into the air after dust removal.

[0085] In this example, preferably, the water pump 4.2 is a submersible pump and is installed and fixed in the tank body of the water tank 4.1.

[0086] This application suggests that, in other embodiments, a gas hood with a gas collection port can also be provided on the opening of the barrel, and the gas will be discharged through the gas collection port after dust removal.

[0087] This application suggests that, in other embodiments, the water tank and the spray body 1 can be installed separately, and the water containing dust particles flows downward along the inner arc surface under its own gravity and is directly discharged (no longer recycled).

For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
