DETAILED DESCRIPTION
[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0025] See also Figure 1-4The utility model provides a technical solution: an anti-blocking ash hopper electric heating device for an electrostatic and bag dust removal system, comprising an ash hopper main body 1, an anti-blocking mechanism 200 for anti-blocking is installed on the inner side of the ash hopper main body 1, and an insulation component 300 for heat insulation is installed on the outer side of the ash hopper main body 1; through the coordinated use of the anti-blocking mechanism 200 on the inner side of the ash hopper main body 1 and the insulation component 300 on the outer side, the energy consumption can be greatly reduced, and the electric heating device is set as an auxiliary secondary device, so that the heating area required for the electric heating device to work is reduced, thereby reducing the power consumption required for heating, and at the same time, the collision between the negative ion charge and the fly ash is used to make the fly ash negatively charged, so that the repulsion between the fly ashes is too large and cannot be bonded into blocks, thereby reducing energy consumption while maintaining excellent anti-blocking ash function, which is very practical.
[0026] In this embodiment, the anti-clogging mechanism 200 is a structure for taking anti-clogging measures on fly ash through heating and the combination of negative ions.
[0027] like Figure 1 , Figure 2 and Figure 4 As shown, the anti-blocking mechanism 200 includes a hot air component installed on the inner side of the ash hopper body 1 and an auxiliary component on the outer side.
[0028] It should be noted that the hot air component is a structure for blowing out hot air with negative ions, and the auxiliary component is a structure for assisting in preventing clogging and being able to detect dust charges.
[0029] In this embodiment, the hot air component is used to blow out hot air with negative ions to collide and mix with fly ash.
[0030] like Figure 1 , Figure 2 and Figure 3 As shown, the hot air assembly includes a first support plate 201 fixedly connected to the right side of the ash hopper body 1, a mounting box 202 is fixedly connected to the top of the first support plate 201, an air inlet pipe 203 is passed through and fixedly connected to the right side of the mounting box 202, a negative ion generator 204 is fixedly installed on the outside of the air inlet pipe 203, a heating device body 205 is fixedly installed on the outside of the air inlet pipe 203, and the left end of the air inlet pipe 203 passes through the left side of the mounting box 202 and the right side of the ash hopper body 1 in sequence and is fixedly connected to the separator 204. The flow box 206, the top of the diverter box 206 is fixedly connected with an ash baffle 207 located on the outside of the air inlet pipe 203, the inner side of the diverter box 206 is fixedly connected with four fixed pipes 208, the outer side of the diverter box 206 is fixedly connected with four groups of evenly distributed exhaust nozzles 209, and the inner side of the ash hopper body 1 is coated with a nano-ceramic coating 213; the nano-ceramic coating 213 can make the contact surface between the ash powder and the inner wall of the ash hopper body 1 smoother, reduce the friction coefficient, and allow the ash powder to fall more smoothly.
[0031] It should be noted that the negative ion generator 204 is located inside the installation box 202, so that the installation box 202 can protect the negative ion generator 204. The heating device body 205 includes a heating wire fixedly installed on the inside of the air intake pipe 203 and a heating device body fixedly installed on the top of the installation box 202. The heating device body is electrically connected to the heating wire through an electric wire or a conductor, and the heating wire can be controlled by the heating device body. The heating wire and the heating device body used for control are both existing publicly available structures, so they will not be elaborated on.
[0032] In addition, an auxiliary rod is fixedly connected between the top of the air inlet pipe 203 and the inner right side wall of the ash hopper body 1, which can provide auxiliary support for the air inlet pipe 203. A circular hole is provided on the top of the ash baffle plate 207 for the bottom end of the air inlet pipe 203 to pass through. The inner side of the circular hole is fixedly connected to the outer side of the air inlet pipe 203. The ash baffle plate 207 is annular, and the top diameter is smaller than the bottom diameter. The bottom diameter of the ash baffle plate 207 is larger than the length of the diverter box 206, so that the ash baffle plate 207 can play a role in blocking ash and protecting the top of the diverter box 206 on the outer side of the air inlet pipe 203.
[0033] At the same time, one end of the four fixed pipes 208 away from the diverter box 206 is fixedly connected to the outside of the intake pipe 203, so that the gas inside the intake pipe 203 can enter the interior of the fixed pipe 208, and the four groups of exhaust nozzles 209 are respectively connected to the interior of the four fixed pipes 208, so that the gas inside the fixed pipe 208 can enter the interior of a corresponding group of exhaust nozzles 209, wherein the number of exhaust nozzles in each group is nine.
[0034] In this embodiment, the auxiliary component is a structure that can use air impact to clear the blockage.
[0035] like Figure 1 and Figure 4 As shown, the auxiliary component includes two second support plates 210 respectively fixedly connected to the left and right sides of the ash hopper body 1, an air cannon 211 is fixedly installed on the top of the second support plate 210, and a conveying pipe 212 is fixedly connected to the side of the air cannon 211 close to the ash hopper body 1.
[0036] It should be noted that the air cannon 211 utilizes the principle of aerodynamics, and its working medium is air. It consists of a differential pressure device and an automatically controlled quick exhaust valve, which instantly converts air pressure energy into air jet kinetic energy, and can generate a strong impact force. It is a clean, pollution-free, low-energy ideal clearing and soot blowing equipment. The opposite ends of the two conveying pipes 212 respectively penetrate the left and right sides of the ash hopper body 1 and tilt downward. The part of the conveying pipe 212 located on the ash hopper body 1 is arranged parallel to the inner wall of the ash hopper body 1, so that the impact air ejected by the conveying pipe 212 can be directly transported and act on the bottom of the ash hopper body 1 for dredging.
[0037] In this embodiment, the heat preservation component 300 is a structure used for heat preservation and moisture absorption.
[0038] like Figure 1 As shown, the insulation component 300 includes a first insulation layer 301 bonded to the outside of the ash hopper body 1, a hygroscopic layer 302 is bonded to the outside of the first insulation layer 301, a second insulation layer 303 is bonded to the outside of the hygroscopic layer 302, a protective layer 304 is bonded to the outside of the second insulation layer 303, and a charge detection sensor 305 is penetrated and fixedly installed on the left side of the ash hopper body 1.
[0039] It should be noted that the first thermal insulation layer 301 and the second thermal insulation layer 303 are glass fiber layers, which can play a good role in thermal insulation. The hygroscopic layer 302 is a pearl cotton layer, which has good moisture absorption and moisture-proof properties. The protective layer 304 is an aluminum foil fireproof cloth, which can play a fire-retardant role while also providing a certain degree of protection for the internal structure. The charge detection sensor 305 can sense the information of the measured electrical quantity by adopting AC charge coupling technology, digital signal processing technology, etc., and can convert the detected information into electrical signals or other required forms of information output according to a certain rule to meet the requirements of information transmission, processing, storage, display, recording and control. It is an existing public technology.
[0040] In addition, the first insulation layer 301, the moisture absorption layer 302, the second insulation layer 303 and the protective layer 304 need to bypass the first support plate 201, the second support plate 210, the conveying pipe 212 and the charge detection sensor 305 during the bonding installation, so that the above structure can be normally installed on the outside of the ash hopper body 1.
[0041] The working principle of the above embodiment is:
[0042] When the device is used to prevent the ash hopper from blocking, the heating device body 205 is started to heat the airflow passing through the air inlet pipe 203, and the negative ion generator 204 is started so that the heated airflow can carry negative ions after passing through. After the treated airflow enters the inside of the diverter box 206, it is respectively transported to the inside of each exhaust nozzle 209 through four fixed pipes 208 for discharge, thereby blowing the fly ash falling from the top of the ash hopper body 1, causing a collision between the fly ash and the negative ion charge, allowing the fly ash to carry negative electricity, thereby increasing the repulsive force between the fly ashes through the principle of like charges repelling each other, and it is impossible to easily stick together into blocks, thereby fundamentally solving the problem of fly ash agglomeration and blockage. At the same time, under the action of the nano-ceramic coating 213, the fly ash can fall smoothly. If necessary, the air cannon 211 can be started regularly to make it impact the inner wall of the ash hopper body 1 through the conveying pipe 212, thereby dispersing the fly ash and clearing the bottom of the ash hopper body 1.
[0043] Compared with the prior art, the anti-clogging ash hopper electric heating device for electrostatic and bag dust removal systems can greatly reduce energy consumption through the coordinated use of the anti-clogging mechanism 200 on the inner side of the ash hopper main body 1 and the insulation component 300 on the outer side. By setting the electric heating device as an auxiliary secondary device, the heating area required for the electric heating device to work is reduced, thereby reducing the power consumption required for heating. At the same time, the collision between negative ion charges and fly ash is used to make the fly ash negatively charged, resulting in excessive repulsion between the fly ashes and the inability to stick together into blocks. Therefore, while reducing energy consumption, it can also maintain excellent anti-clogging ash function. It is very practical and solves the problem that the existing ash hopper anti-clogging technology consumes a lot of energy.
[0044] The electrical components appearing in the article are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device for control such as a computer, and the existing public power connection technology is not described in detail in the article.
[0045] It should be noted that the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "comprises a ..." does not exclude the existence of other identical elements in the process, method, article or device including the element.
[0046] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that many changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention.
