Description

Technical Field

[0001] This utility model relates to the field of demister technology, specifically to a demister with dust removal function. Background Technology

[0002] Demisters are crucial components of desulfurization towers. Their function is to capture mist particles and slurry droplets entrained in the flue gas during the spray absorption process. The efficiency of a demister depends not only on its structure but also on the density and size of the mist particles. The atomized particle size of the nozzle is related to the viscosity of the absorbent, the spray pressure, and the nozzle structure. Demisters are used to separate liquid droplets entrained in the gas in the tower, effectively removing mist droplets and preventing their emission into the atmosphere. They are typically installed at the top of the tower.

[0003] Existing demisters with dust removal functions cannot achieve centrifugal separation when small droplets collide with the demister. Due to the small size of the particles, they cannot be fully demisted, resulting in unsatisfactory removal effect for small droplets and significant limitations. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the present invention provides a demister with dust removal function to overcome the above-mentioned technical problems existing in the existing related technologies.

[0005] A demister with dust removal function includes a primary demister assembly, a secondary demister assembly, and a tertiary demister assembly. Several support frames are fixedly connected between the primary, secondary, and tertiary demister assemblies. Several mounting seats are fixedly installed on one side of two of the support frames. An enhancement component is provided at one end of each mounting seat. The enhancement component includes a connecting pipe, a valve, and a nozzle. The valve is fixedly installed at one end of the connecting pipe, and the nozzle is fixedly installed at one end of the valve. A connecting frame is fixedly installed between the secondary and tertiary demister assemblies. A fixing seat is fixedly installed on one side of the connecting frame. A second water pipe is fixedly installed at one end of the fixing seat. Several water spray components are provided on the outer wall of the second water pipe.

[0006] Preferably, the enhancement component further includes a water pipe, which is fixedly installed at one end of the mounting base, and one end of the connecting pipe is fixedly connected to the water pipe and communicates with the inner wall of the water pipe.

[0007] Preferably, the valve is fixedly installed on the connecting pipe.

[0008] Preferably, a fixing component is fixedly installed at one end of each of the primary defogging component, the secondary defogging component, and the tertiary defogging component.

[0009] Preferably, a fixing frame is fixedly installed between the two support frames.

[0010] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0011] 1. This utility model provides a demister with dust removal function. Through the cooperation between the primary demister component, the secondary demister component, the tertiary demister component and the enhancement component, after the valve is opened, the nozzle sprays water from the water pipe onto the tiny particles, causing the volume of the tiny particles to increase. Then, the particles are eliminated by the secondary and tertiary demister components, thus improving the demisting and dust removal effect.

[0012] 2. This utility model provides a demister with dust removal function. Through the cooperation of the connecting frame, fixing base, water pipe, water spraying component, first-stage demister component, second-stage demister component and third-stage demister component, the demister is sprayed on the particles on the basis of the enhanced component spraying, which further increases the volume of the particles, thereby further improving the demisting and dust removal effect.

[0020] To make the technical means, creative features, objectives, and effects of this utility model easier to understand, the following describes this utility model in conjunction with specific embodiments:

[0021] like Figure 1-5As shown, this utility model provides a demister with dust removal function, including a primary demister assembly 1, a secondary demister assembly 2, and a tertiary demister assembly 3. Several support frames 106 are fixedly connected between the primary demister assembly 1, the secondary demister assembly 2, and the tertiary demister assembly 3. Several mounting seats 101 are fixedly installed on one side of two support frames 106. An efficiency-enhancing component 100 is provided at one end of each mounting seat 101. The efficiency-enhancing component 100 includes a connecting pipe 103, a valve 104, and a nozzle 105. The valve 104 is fixedly installed at one end of the connecting pipe 103, and the nozzle 105 is fixedly installed at the other end. A connecting frame 4 is fixedly installed between the secondary demisting component 2 and the tertiary demisting component 3, and a fixing seat 5 is fixedly installed on one side of the connecting frame 4. A water pipe 6 is fixedly installed at one end of the fixing seat 5. Several water spray components 601 are provided on the outer wall of the water pipe 6. The enhancement component 100 also includes a water pipe 102, which is fixedly installed at one end of the mounting seat 101. One end of the connecting pipe 103 is fixedly connected to the water pipe 102 and communicates with the inner wall of the water pipe 102. The valve 104 is fixedly installed on the connecting pipe 103.

[0022] To ensure that small-diameter dust particles carried in the flue gas can be captured by the demister to the greatest extent, after the flue gas passes through the primary demister assembly 1, most of the droplets carried by it have been removed. Then, valve 104 is opened, and water in water pipe 102 flows through connecting pipe 103 to nozzle 105. Then, nozzle 105 sprays water onto the tiny particles, causing the tiny particles to increase in size after being wetted. They then collide and separate with the secondary and tertiary demister assemblies 2 and 3, thereby discharging clean flue gas and improving the demisting and dust removal effect. At the same time, the operator can also activate several water spray assemblies 601 to further increase the size of the particles, thereby further improving the demisting and dust removal effect. The room temperature water source in water pipe 1 is atomized by the nozzle to form a fine mist, which is sprayed downwards. The tiny dust particles carried by the high-temperature flue gas come from bottom to top, and after contact with condensation, the volume of the fine mist increases, which can encapsulate some of the tiny dust particles. They are then eliminated by the secondary and tertiary demister assemblies above, improving the demisting and dust removal effect.

[0023] like Figure 1 As shown, in one embodiment, a fastener 108 is fixedly installed at one end of the primary defogging component 1, the secondary defogging component 2, and the tertiary defogging component 3, and a fixing bracket 107 is fixedly installed between the two support brackets 106.

[0024] The fastener 108, support frame 106 and fixing frame 107 can improve the fixing effect between the first-stage demisting component 1, the second-stage demisting component 2 and the third-stage demisting component 3, and improve the stability of the equipment and have strong applicability;

[0025] The primary defogging component 1, the secondary defogging component 2, and the tertiary defogging component 3 are all existing technologies and will not be explained here.

[0026] The working principle of this demister with dust removal function will be explained in detail below:

[0027] To ensure that small-diameter dust particles carried in the flue gas can be captured by the demister to the greatest extent, most of the droplets carried by the flue gas have been removed after passing through the primary demister assembly 1. Then, valve 104 is opened, and water in water pipe 102 flows through connecting pipe 103 to nozzle 105. Then, nozzle 105 sprays water onto the tiny particles, causing the tiny particles to increase in size after being wetted. They then collide and separate with the secondary demister assembly 2 and the tertiary demister assembly 3, thereby discharging clean flue gas and improving the demisting and dust removal effect. At the same time, the operator can also activate several water spray components 601 to further increase the size of the particles, thereby further improving the demisting and dust removal effect.

[0028] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
