Description

Technical Field

[0001] This utility model relates to the field of sprayer technology, and in particular to a high-speed sprayer for a waste incineration flue gas purification device. Background Technology

[0002] The atomizer has an internal feed port for lime slurry (Ca(OH)2), calcium hydroxide, commonly known as lime slurry or lime water, which is a hydroxide containing calcium. Its chemical formula is Ca(OH)2, composed of one calcium ion and two hydroxide ions. Its molecular weight is 74.10.

[0003] Traditional waste incineration flue gas purification equipment uses a high-speed sprayer to atomize lime slurry mixed with water. The resulting atomized particles have a diameter of 40 micrometers and react with acidic gases in the flue gas, resulting in low utilization and affecting the efficiency of atomization. Utility Model Content

[0004] In order to solve the problems existing in the background technology, the present invention provides a high-speed sprayer in a waste incineration flue gas purification device that can reduce the atomizer particle size.

[0005] To address the problems in existing technologies, this utility model provides a high-speed sprayer for a waste incineration flue gas purification device, comprising a main body, a mounting plate fixedly installed on the top of the main body, and an ultrasonic oscillator fixedly installed on the main body. The ultrasonic waves emitted by the oscillator cause a dramatic change in sound pressure when propagating in the liquid, resulting in intense cavitation and emulsification of the liquid. Millions of tiny cavitation bubbles are generated per second. These bubbles are rapidly generated in large quantities under the action of sound pressure and continuously and violently burst, generating a powerful impact force and negative pressure suction force, which is sufficient to allow acidic gases to fully combine and react with lime slurry.

[0006] Specifically, a set of functional connectors is fixedly installed on the top of the main body of the device, one end of a connecting pipe is fixedly connected to the side wall of the main body of the device, a fixing ring is fixedly installed on the connecting pipe, and a set of atomizing discs is fixedly installed at the bottom of the main body of the device. The atomizing discs include a mist outlet ring, a threaded frame, a threaded disc, and an atomizing plate. The top of the mist outlet ring is fixedly connected to the bottom of the main body of the device, and a vent hole is opened on the mist outlet ring.

[0007] Specifically, the bottom of the misting ring is fixedly connected to the top of the threaded frame, and a set of threaded discs are threadedly connected inside the threaded frame. A set of atomizing tubes is fixedly installed inside the main body of the device, and a set of connecting nozzles is fixedly installed at the bottom of the atomizing tubes. The connecting nozzles include a double-layer air vent, an oil leakage hole, a barrier ring, and a sieve plate.

[0008] Specifically, the top of the double-layer air cylinder is fixedly connected to one end of the atomizing tube. The double-layer air cylinder is composed of two sets of hollow cylinders. Multiple sets of oil leakage holes are opened on the side wall of the innermost hollow cylinder of the double-layer air cylinder. A set of blocking rings is fixedly installed at the bottom of the oil leakage holes. A set of sieve plates is fixedly connected to the bottom of the hollow cylinder inside the oil leakage holes.

[0009] The beneficial effects of this utility model are as follows: The high-speed sprayer in the waste incineration flue gas purification equipment of this utility model uses ultrasonic waves emitted by its ultrasonic oscillator to cause a dramatic change in sound pressure when the ultrasonic waves propagate in the liquid, resulting in strong cavitation and emulsification of the liquid. Millions of tiny cavitation bubbles are generated every second. These bubbles are rapidly generated in large quantities under the action of sound pressure and continuously and violently burst, generating a powerful impact force and negative pressure suction force, which is sufficient to fully combine and react with the acidic gas and lime slurry. This reduces the particle size of the lime slurry inside the atomizer to 100 nanometers, thereby improving its utilization rate. Attached Figure Description

Detailed Implementation

[0016] To make the technical methods, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0017] like Figure 1-4The high-speed sprayer in a waste incineration flue gas purification device includes a main body 1. The mounting plate 110 is fixedly installed on the top of the main body 1, and the ultrasonic oscillator 112 is fixedly installed on the main body 1. The ultrasonic waves emitted by the ultrasonic oscillator 112 cause a dramatic change in sound pressure when propagating in the liquid, resulting in strong cavitation and emulsification of the liquid. Millions of tiny cavitation bubbles are generated per second. These bubbles are rapidly generated in large quantities under the action of sound pressure and continuously and violently burst, generating a powerful impact force and negative pressure suction force, which is sufficient to allow acidic gases to fully combine and react with lime slurry.

[0018] Preferably, a set of functional connectors 113 are fixedly installed on the top of the device body 1, one end of a connecting pipe 114 is fixedly connected to the side wall of the device body 1, a fixing ring 115 is fixedly installed on the connecting pipe 114, and a set of atomizing discs 2 are fixedly installed at the bottom of the device body 1. The atomizing disc 2 includes a mist outlet ring 210, a threaded frame 211, a threaded disc 212, and an atomizing plate. The top of the mist outlet ring 210 is fixedly connected to the bottom of the device body 1, and a vent hole is provided on the mist outlet ring 210.

[0019] The bottom of the mist ring 210 is fixedly connected to the top of the threaded frame 211. A set of threaded discs 212 are internally threaded into the threaded frame 211. A set of atomizing tubes 116 are fixedly installed inside the main body 1 of the device. A set of connecting nozzles 3 are fixedly installed at the bottom of the atomizing tubes 116. The connecting nozzles 3 include a double-layer ventilation cylinder 311, an oil leakage hole 312, a barrier ring 313, and a sieve plate 314. The top of the double-layer ventilation cylinder 311 is fixedly connected to one end of the atomizing tube 116. The double-layer ventilation cylinder 311 is composed of two sets of hollow cylinders. Multiple sets of oil leakage holes 312 are opened on the innermost hollow cylinder sidewall of the double-layer ventilation cylinder 311. A set of barrier rings 313 are fixedly installed at the bottom of the oil leakage hole 312. A set of sieve plates 314 are fixedly connected to the bottom of the hollow cylinder inside the oil leakage hole 312.

[0020] (1) In this utility model, some oil is used inside the main body 1 of the equipment. After the equipment is started, some of the oil will flow out along 310. A set of double-layer ventilators 311 is fixedly connected to one end of 310. Multiple sets of oil leakage holes 312 are opened on the inner ring of the double-layer ventilator 311. The oil will flow into the interlayer inside the double-layer ventilator 311 along the oil leakage holes 312, thereby preventing it from clogging the screen plate 314. The oil dripping from 310 will fall into the threaded frame 211. The staff only needs to unscrew the threaded disc 212 regularly to clean it, thereby reducing the clogging situation.

[0021] (2) In this utility model, there is a set of atomizing plates inside the ultrasonic oscillator 112, which are generally made of piezoelectric ceramics and are generally circular. Piezoelectric ceramics are a type of piezoelectric element. Piezoelectric element has a piezoelectric effect, which can be divided into positive piezoelectric effect and inverse piezoelectric effect.

[0022] (3) The positive piezoelectric effect is manifested as follows: when an external force is applied to the surface of a piezoelectric element, the surface of the piezoelectric element will generate charge due to deformation, and thus become charged. In this process, mechanical energy is converted into electrical energy.

[0023] (4) The inverse piezoelectric effect is manifested as follows: when an electric current is applied to both ends of a piezoelectric element, the piezoelectric element will deform. If a high-frequency current is applied, the piezoelectric element will deform repeatedly, that is, vibrate. In this process, electrical energy is converted into mechanical energy.

[0024] (5) The ultrasonic oscillator 112 utilizes this inverse piezoelectric effect to convert electrical energy into mechanical energy. As explained earlier regarding the inverse piezoelectric effect, applying a high-frequency voltage causes the piezoelectric element of the atomizing plate to oscillate. The ultrasonic oscillator 112 generates a 0.65MHz high-frequency voltage, which is applied to the atomizing plate through a coupling capacitor. The atomizing plate oscillates after being excited by the oscillation circuit. This oscillation signal is then fed back to the base of the oscillating tube through the coupling capacitor, causing the oscillation circuit to resonate at 1.7MHz. Under the influence of this strong oscillating electrical energy, the atomizing plate converts this electrical energy into mechanical energy, thereby breaking the lime slurry into tiny particles of about 100 nanometers.

[0025] Working principle: When the main body of the device 1 is started, the ultrasonic waves emitted by its ultrasonic oscillator 112 cause a dramatic change in sound pressure as they propagate in the liquid, resulting in intense cavitation and emulsification. Millions of tiny cavitation bubbles are generated per second. These bubbles are rapidly generated in large quantities under the influence of sound pressure and continuously and violently burst, producing a powerful impact force and negative pressure suction. This is sufficient to allow the acidic gas to fully combine and react with the lime slurry, reducing the lime slurry particle size inside the atomizer to 100 nanometers. Some oil is used inside the main body of the device 1. After the equipment is started, some of the oil will flow out along 310. A set of double-layer venting cylinders 311 is fixedly connected to one end of 310. Multiple sets of oil leakage holes 312 are opened on the inner ring of the double-layer venting cylinders 311. The oil will flow into the interlayer inside the double-layer venting cylinders 311 along the oil leakage holes 312, thereby preventing it from clogging the screen plate 314. The oil dripping from 310 will fall into the threaded frame 211. The staff only needs to unscrew the threaded disc 212 periodically to clean it, thereby reducing the possibility of clogging.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model.
