Description
Technical Field
[0001] The utility model relates to the technical field of dust treatment, in particular to a coal conveying and dust removal device for a power plant. Background Art
[0002] Coal transportation in power plants refers to the process of transporting coal from coal mines or warehouses to thermal power plants for power generation through various means. Coal transportation in power plants is one of the important links in the operation of thermal power plants. Coal is one of the main fuels for thermal power generation. The heat energy generated by burning coal drives the generator set to generate electricity. The efficient operation of coal transportation in power plants is of great significance to ensure stable power generation in power plants, reduce energy production costs, and reduce environmental pollution. Coal will release a large amount of dust and particulate matter during the combustion process. These particulate matter are harmful to the environment and human health. Coal combustion will release harmful gases such as sulfur dioxide and nitrogen oxides, as well as solid particulate matter. These substances will cause air pollution, affect air quality, and cause harm to the surrounding environment. Dust and particulate matter will accumulate inside the equipment. Therefore, dust removal treatment of dust and particulate matter released during coal transportation in power plants not only meets environmental protection requirements, but also helps protect equipment and personnel health.
[0003] During use, existing dust removal devices usually use large nozzles for direct spraying, which not only consumes a large amount of water, but also easily causes moisture in the power plant workshop. At the same time, the dust suppression effect is poor, which affects the service life of the equipment and the health of personnel. When used in temperatures below zero, the water flow cannot be heated, which will cause the water flow to freeze and affect the dust removal effect in the power plant workshop.
[0004] Therefore, it is necessary to provide a new power plant coal conveying and dust removal device to solve the above technical problems. Utility Model Content

DETAILED DESCRIPTION
[0021] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.
[0022] See also Figure 1-4 As shown, a coal conveying and dust removal device for a power plant includes a base plate 1, and also includes: an air compressor body 2 arranged on the top of the base plate 1, a first air outlet pipe 3 is arranged on the outer side of the air compressor body 2, an air storage tank 4 is arranged at one end of the first air outlet pipe 3, and a valve 5 and a second air outlet pipe 6 are respectively arranged on the outer side of the air storage tank 4; a dust removal component 7 is arranged on the top of the base plate 1, a heating element 8 is arranged on the top of the dust removal component 7, the dust removal component 7 includes a shell 71, an acoustic oscillator 72 is arranged at the bottom of the inner cavity of the shell 71, a support plate 73 is fixedly connected to the inner wall of the shell 71, and a first dust removal component 74 and a second dust removal component 75 are respectively arranged inside the shell 71.
[0023] It should be noted that: one end of the first air outlet pipe 3 is connected to the outside of the air storage tank 4, and one end of the second air outlet pipe 6 passes through the shell 71 and is connected to the sonic oscillator 72. The air is compressed by the air compressor body 2, and the compressed air enters the inside of the sonic oscillator 72. The water is highly atomized by the sonic boom of the high-frequency sound waves to produce fine water mist particles below 10μm. When the particle size of the water mist particles is less than 10μm and reaches the dry mist level, the surface tension of the droplets decreases, and the adhesion between the particles will become greater and greater. Therefore, in the two-phase flow of "fine dust particles-fine water mist particles" with dust particles as the core, particles are easily combined together, so that the entire particle continues to grow and finally settles down, so as to achieve the purpose of removing dust particles. The water mist particles are sprayed out through the dust removal component 7 to remove dust from the power plant workshop. The inside of the shell 71 is heated by setting a heating element 8 to avoid the problem of water flow freezing caused by low temperature.
[0024] refer to Figure 2As shown, the first dust removal component 74 includes a first water pump 741 arranged at the bottom of the inner cavity of the shell 71, and a first water outlet pipe 742 arranged at one end of the first water pump 741; the first dust removal component 74 also includes a first water outlet box 743 arranged at one end of the first water outlet pipe 742, and a first nozzle 744 arranged at the top of the first water outlet box 743; a water tank 9 is arranged on the top of the bottom plate 1, a water inlet 10 is arranged on the top of the water tank 9, and a third water pump 11 is arranged on the top of the bottom plate 1; one end of the third water pump 11 is connected to the outside of the water tank 9, and the other end passes through the shell 71 and is connected to the sonic oscillator 72. One end of the first water outlet pipe 742 is connected to the support plate 73. The first water pump 741 is started to extract the water mist inside the sonic oscillator 72, and the top of the device is sprayed through the first water outlet box 743 and the first nozzle 744 to increase the spray dust removal range.

The second water pump 751 is started to extract water mist, which is sprayed through the second water outlet box 754 and the second nozzle 755 to spray and remove dust around the equipment in the workshop, thereby improving the dust removal effect. The number of second water outlet boxes 754 and second nozzles 755 can be controlled according to the number and position of equipment to ensure the dust removal range.
[0026] refer to Figure 4 As shown, the heating element 8 includes a fan 81, a protective shell 82 arranged at one end of the fan 81, and a heating rod 83 arranged inside the protective shell 82; the heating element 8 also includes an air outlet pipe 84 arranged at one end of the protective shell 82, an air outlet branch pipe 85 arranged outside the air outlet pipe 84, and an air outlet cover 86 arranged at one end of the air outlet branch pipe 85; the heating rod 83 is a prior art, the heating rod 83 is started for heating, the fan 81 is started to blow air into the protective shell 82, the wind flow is heated by the heating rod 83, and the hot air is blown into the shell 71 by the air outlet cover 86 to heat the inside of the shell 71, so as to avoid the problem of water flow freezing when the temperature is below zero and improve the service life.
[0027] Working principle: When the device is in use, the air is compressed by the air compressor body 2, and the compressed air enters the interior of the acoustic oscillator 72. The water is highly atomized through the sonic boom of high-frequency sound waves to produce fine water mist particles below 10μm. When the particle size of the water mist particles is less than 10μm and reaches the dry fog level, the surface tension of the droplets decreases, and the adhesion between the particles becomes larger and larger. Therefore, in the two-phase flow of "fine dust particles-fine water mist particles" with dust particles as the core, the particles are easily combined with each other, so that the whole particle keeps growing and finally settles down, so as to achieve the purpose of removing dust particles. The first water pump 741 is started to extract the water mist inside the acoustic oscillator 72, and the water mist is discharged through the first water pump 741.

The wind flow is heated by the heating rod 83, and the hot air raises the air outlet hood 86 to blow into the shell 71 to heat the inside of the shell 71, thereby avoiding the problem of water flow freezing when the temperature is below zero and increasing the service life.
