Description

Ultrasonic atomizing nozzle

technical field

The utility model relates to an ultrasonic atomizing nozzle, which is especially suitable for places with serious dust pollution, such as working faces in coal mines, air return tunnels, coal washing plants, cement plants, power plants and the like.

Background technique

The nozzle is to convert the water flow into water mist. Water mist is a resource needed in the workplace, and most of it is used to reduce dust. At present, most nozzles are ordinary low-pressure nozzles. Whether it is a single-head or multi-head nozzle, no matter what kind of water guide core it contains, there are low atomization rate, low kinetic energy of water mist, and relatively small atomization cone angle. Small size, high resource consumption and other issues.

There is a direct relationship between water mist particles and dust removal efficiency, that is, the smaller the water mist particles, the higher the dust removal efficiency. The low atomization rate means that the water mist particles are large. Therefore, ordinary low-pressure nozzles are used as dust removal facilities, which are the facilities with the worst effect.

Many places with serious dust pollution, such as coal mine working face, return air tunnel, coal washing plant, cement plant, power plant, etc., use ordinary low-pressure nozzles as dust removal facilities. In order to achieve dust reduction effect, increase the number of nozzles and increase water consumption. , the dust can only be reduced to a certain extent and the pollution still exists, but the excessive use of water source will cause the production to be passive and the water flow to be a disaster.

Detailed ways

Below in conjunction with the embodiment of accompanying drawing, the utility model is further described:

As shown in the accompanying drawings, the ultrasonic atomizing nozzle is mainly composed of a resonant cup 1, a core body 2, a casing 3 and a seal 8. There is a through hole in the center of the core body 2, which is located in the casing 3, and the head of the casing 3 The outlet at the top is in the shape of a trumpet, and the outer end surface of the outlet is provided with a resonant cup 1 which is threadedly connected with the shell 3, and the front part of the shell 3 is provided with a concave conical surface around its head to meet the secondary resonance and slow down the kinetic energy of the fluid . The tail of the housing 3 is provided with an adjusting nut 5 for adjusting the movement of the core body 2 back and forth; the front of the outer cylindrical surface of the housing 3 is provided with a water interface 6, and the rear part is provided with an air interface 6, and is provided with an installation threaded hole 4; the core body 2 The front and rear positions corresponding to the air interface 7 are set on the sealing ring 8, and there are ventilation holes connected to the air interface 7; the water interface 6 is located at the front of the sealing ring 8, and the corresponding core body 2 is a water guide core. The water guide core is matched with the inner hole of the housing 3 . The gap matching surface between the water guide core and the inner hole of the shell 1 is a conical surface; the positions of the core body 2 and the water interface 6 and the air interface 7 are provided with water guide and air guide grooves. The core body 2 cooperates with the shell 3 to guide the water and air input from different positions to the meeting point, that is, the collision point to generate resonance. There is a water guide groove on the outside of the front end. The left end is the adjusting nut 5, and the center is the air guide hole. There are two seals in the middle. The tank is used to isolate the air source and the water source. The shell 3 is the basis of the ultrasonic atomizing nozzle. It not only needs to be positioned through the external mounting thread 4, but also guides the water and air input from different positions to the meeting point, that is, the collision point, to generate resonance through the clearance cooperation with the core body 2. The positioning requirements of the resonance cup 1 must also be met. The adjusting nut 5 is located at the rear end of the core body 2 and is used for adjusting the resonance point and water consumption. The water interface 6 is located on the middle right side of the housing 3, and the pressure water is input into the housing 3 through the joint. The gas interface 7 is located on the left side of the housing 3, and the pressure gas is input into the housing 3 through the joint. The sealing ring 8 is located in the sealing groove on the core body 2, so as to isolate the pressure water and the pressure gas during the cooperation between the shell 3 and the core body 2, and prevent the pressure gas from leaking out during the adjustment process.

Its working principle: add seals to different interfaces on the side of the housing 3 to install the air source and water source connectors, turn the adjusting nut 5 with moderate force and not get stuck, adjust the resonance cup 1 to the best position and lock it. The air source and the water source supply a certain air pressure and water pressure, the air source inputs the pressure gas from the air interface 7, and the water source inputs the pressure water from the water interface 6. The pressure gas input through the air interface 7 enters the space formed by the shell 3, the core body 2 and the seal 8, and then enters the center hole of the core body 2 from the air hole process hole in the center and flows to the right, reaching the right end of the core body 2 and the shell body 3 at the cone surface. The pressure water input through the water interface 6 enters the space formed by the right casing 3, the core body 2 and the seal 8, the pressure water must flow forward, pass through the water guide core to generate a rotating water flow, and then flow along the core body 2 and the front end of the casing 3 In the gap between the cone surfaces, the flow that rotates at a high speed at the cone angle formed by the cone surface meets the airflow that flows to the right at a high speed. The water pressure arriving at the same time compresses and expands instantaneously due to the continuation of the air pressure, making the water flow diffuse in the direction of the reverse cone angle. In the limited space at the front end of the shell 3 and the core body 2, the water flow and the air flow repeatedly collide, that is, compress and expand, and the phenomenon of ultrasonic resonance occurs, and the water flow is intensified into fine particles and ejected outward at high speed according to the angle after resonance. The high-speed water mist flow outside the casing 3 enters the resonance cup 1 forward, and the high-speed water mist flow collides and resonates along the linear direction in the volume of the resonance cup 1, that is, the secondary resonance makes the water mist particles more fine, and the water mist flow speed is extremely high. With a large slowdown, the final water mist diffuses slowly from around the resonance cup 1 like a cloud. Adjust the adjusting nut 5 at the rear of the core body 2 so that the resonance frequency is in the ultrasonic range, and the water consumption can be controlled in an ideal range.
