Description

Technical Field

[0001] This application relates to the field of incinerator technology, specifically to a dioxin adsorption device applied in an incinerator. Background Technology

[0002] An incinerator is a type of waste disposal equipment. Its principle is to use the combustion of fuels such as coal, fuel oil, or natural gas to carbonize the waste at high temperatures, thus achieving disinfection. However, during the incineration process, the waste generates a large amount of toxic gases after combustion within the furnace. The treatment of dioxins, in particular, remains a pressing problem for those working in the field.

[0003] Dioxins are extremely toxic, have a high melting point, are non-polar, and are poorly soluble in water. They remain stable in strong acids and alkalis and can persist in the environment for extended periods. The solubility and volatility of PCDD / Fs decrease with increasing chlorination. Microbial degradation, hydrolysis, and photodecomposition in the natural environment have minimal impact on the molecular structure of dioxins. Currently, dioxin treatment typically uses activated carbon adsorption. When the flue gas volume is large and the dioxin content is high, continuous replenishment of activated carbon is necessary. Existing incinerator technologies suffer from slow activated carbon replacement efficiency and cumbersome operation during tail gas treatment. Utility Model Content

[0004] In view of the above problems, this application provides a dioxin adsorption device for use in incinerators, which can replace activated carbon without affecting the use of the equipment. By timely discharging the old activated carbon and replenishing it with new activated carbon, the adsorption performance of the activated carbon is guaranteed, thereby improving the adsorption effect of dioxins in the exhaust gas.

[0005] According to one aspect of the embodiments of this application, a dioxin adsorption device is provided for use in an incinerator. A dioxin adsorption device applied to an incinerator includes a purification box connected to the incinerator. A storage box is located at the top of the purification box, and the bottom of the storage box extends into the purification box via a discharge pipe. A conical structural platform is located within the inner cavity of the purification box, and a conical funnel is fitted around the outer periphery of the structural platform. Multiple air vents are formed on the sidewall of the conical funnel. The conical funnel and the structural platform together enclose an adsorption chamber. A discharge pipe is connected to the bottom of the conical funnel, and the discharge pipe slopes downward and extends to the outside of the storage box. A drive motor is connected to the top of the structural platform via a fixing component. The output shaft of the drive motor is connected at an angle to a uniform distribution rod. The other end of the uniform distribution rod extends radially along the top surface of the structural platform and forms a clamping end. The bottom of the discharge pipe is connected to a uniform distribution tube via a rotating joint, and the other end of the uniform distribution tube extends into the adsorption chamber. The clamping end clamps the middle of the uniform distribution tube.

[0006] In some embodiments, the feeding pipe is a steel pipe, the rotary joint is cylindrical, a spiral rod is provided on the inner bottom wall of the rotary joint, a support ring is provided on the outer wall of the feeding pipe, an overlapping ring is provided on the top of the rotary joint, the overlapping ring overlaps the support ring, one end of the uniformly distributed pipe is connected to the side wall of the rotary joint, and the other end extends downwards.

[0007] In some embodiments, a waste discharge box is provided on the outside of the purification box, a negative pressure fan is connected to the waste discharge box, the outlet end of the negative pressure fan is connected to the inside of the purification box, and an air inlet pipe is connected to the waste discharge box.

[0008] In some embodiments, a plurality of brushes are provided on the top inner wall of the conical funnel, and the other end of the brushes is radiating and extends to the outer wall of the construction platform.

[0009] In some embodiments, a vibration motor is provided at the bottom of the conical funnel, and the vibrating end of the vibration motor abuts against the bottom wall of the conical funnel.

[0010] In some embodiments, at least three support rods are vertically fixed below the construction platform, and the three support rods pass through the bottom wall of the conical funnel and are fixedly connected to the purification box.

[0011] The beneficial effects of this application are as follows: By setting a conical funnel and a conical structural platform, an adsorption chamber is formed between the structural platform and the conical funnel. This allows the activated carbon to be effectively spread evenly in the adsorption chamber to increase the surface area. Ventilation holes are provided on the outer wall of the conical funnel, allowing toxic gases in the purification chamber to enter the adsorption chamber through these holes, where dioxins are adsorbed by the activated carbon. By cooperating with components such as a drive motor, a distribution pipe, and a distribution rod located above the structural cylinder, activated carbon from the storage tank can be evenly added to the adsorption chamber as the distribution pipe slowly rotates around it. Activated carbon at the bottom of the adsorption chamber is discharged through the discharge pipe, while activated carbon at the top falls to the bottom. This cycle allows for timely removal and replacement of deactivated activated carbon. In summary, this application allows for activated carbon replacement without affecting equipment operation, and the entire activated carbon replacement process is simple and convenient.

[0018] The embodiments of the technical solution of this application will be described in detail below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of this application, and are therefore merely examples and should not be used to limit the scope of protection of this application.

[0019] For details, please refer to Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the overall cross-sectional structure of the dioxin adsorption device applied to an incinerator, as provided in an embodiment of this application. Figure 2This is a partial structural diagram of the adsorption chamber and its connection points provided in an embodiment of this application. The dioxin adsorption device 100 applied to an incinerator includes a purification box 110 connected to the incinerator. The purification box 110 is connected to the incinerator's exhaust gas pipeline. After the incinerator exhaust gas passes through the purification box 110 to remove dioxins and other toxic gases, it is discharged again along the pipeline. A storage box 120 is provided at the top of the purification box 110, and activated carbon is stored in the storage box 120. The bottom of the storage box 120 extends into the purification box 110 through a feed pipe 121, and activated carbon is continuously replenished into the purification box 110 through the feed pipe 121. A conical structural platform 130 is provided in the inner cavity of the purification box 110. The shape of the structural platform 130 matches that of the conical funnel 140 to form an adsorption chamber 150. The structural platform 130 can also be used to install and support components such as a drive motor 160. A conical funnel 140 is fitted around the outer periphery of the structural platform 130. Multiple air vents 141 are provided on the side wall of the conical funnel 140. The conical funnel 140 and the structural platform 130 together form an adsorption chamber 150. The adsorption chamber 150 allows activated carbon to have a larger contact area with the combustion exhaust gas from the incinerator after entering the chamber, thus effectively increasing the adsorption effect. A discharge pipe 142 is connected to the bottom of the conical funnel 140. The discharge pipe 142 slopes downwards and extends to the outside of the storage tank 120. Activated carbon in the conical funnel 140 flows into the storage tank 120 through the discharge pipe 142 and is discharged. The activated carbon added at the top is of higher activity. As the activated carbon in the conical funnel 140 is gradually discharged along the discharge pipe 142, the activated carbon in the adsorption chamber 150 will also descend layer by layer and eventually be discharged along the discharge pipe 142 when it is about to deactivate. A drive motor 160 is connected to the top of the structure platform 130 via a fixing member. The output shaft of the drive motor 160 is angled to a uniform distribution rod 161, allowing the drive motor 160 to rotate the uniform distribution member around its output shaft. The other end of the uniform distribution rod 161 extends radially along the top surface of the structure platform 130, forming a clamping end 162. The bottom of the feed pipe 121 is connected to a uniform distribution tube 123 via a rotating joint 122. The other end of the uniform distribution tube 123 extends into the adsorption chamber 150, and the clamping end 162 clamps the middle of the uniform distribution tube 123. As the uniform distribution rod 161 is driven and rotated, it rotates the uniform distribution tube 123 via its clamping end 162, causing the activated carbon inside the feed pipe 121 to slowly and evenly fall into the adsorption chamber 150 through the rotating joint 122 and the uniform distribution tube 123.

[0020] As can be seen from the above, in this embodiment, by setting a conical funnel 140 and a conical structural platform 130, the structural platform 130 and the conical funnel 140 can enclose and form an adsorption chamber 150, so that the activated carbon can be effectively spread out in the adsorption chamber 150 to increase the surface area. The outer wall of the conical funnel 140 is provided with a vent hole 141, so that the toxic gas in the purification box 110 can enter the adsorption chamber 150 through the vent hole 141, and the dioxins will be adsorbed by the activated carbon. By setting a drive motor 160, a uniform distribution pipe 123 and a uniform distribution rod 161 above the structural cylinder and cooperating with each other, the activated carbon in the storage box 120 can be evenly added into the adsorption chamber 150 as the uniform distribution pipe 123 slowly rotates around the adsorption chamber 150. After the activated carbon at the bottom of the adsorption chamber 150 is discharged through the discharge pipe 142, the activated carbon at the top falls to the bottom. This cycle can be used to discharge and replace the deactivated activated carbon in a timely manner. In summary, this application allows for the replacement of activated carbon without affecting the use of the equipment, and the entire activated carbon replacement process is simple and convenient.

[0021] In some embodiments, the feed pipe 121 is a steel pipe, the rotary joint 122 is cylindrical, a spiral rod is provided on the inner bottom wall of the rotary joint 122, a support ring 121a is provided on the outer wall of the feed pipe 121, and an overlapping ring 122a is provided on the top of the rotary joint 122, which overlaps the support ring 121a. One end of the evenly distributed pipe 123 is connected to the side wall of the rotary joint 122, and the other end extends downward at an angle. In this embodiment, with the above arrangement, the rotary joint 122 is overlapped on the feed pipe 121 by the overlapping ring 122a without affecting the rotation of the rotary joint 122 with the evenly distributed pipe 123. During the rotation of the rotary joint 122, the spiral tube inside rotates relative to the activated carbon in the feed pipe 121, thereby causing the activated carbon to fall quickly into the evenly distributed pipe 123, avoiding material jamming.

[0022] In some embodiments, a waste discharge box 170 is provided on the outside of the purification box 110. A negative pressure fan 171 is connected to the waste discharge box 170, and the outlet end of the negative pressure fan 171 is connected to the inside of the purification box 110. An air inlet pipe 172 is connected to the waste discharge box 170. In this embodiment, when it is necessary to discharge the deactivated activated carbon in the purification box 110, the valve between the waste discharge box 170 and the purification box 110 can be closed first. Then, the negative pressure fan 171 draws outside air into the waste discharge box 170 and draws the air in the waste discharge box 170 into the purification box 110 for adsorption again. This effectively prevents the leakage of harmful gases when the waste discharge box 170 is opened.

[0023] In some embodiments, a plurality of brushes 180 are provided on the inner top wall of the conical funnel 140, and the other end of the brushes 180 is radiating and extends to the outer side wall of the structure platform 130. In this embodiment, since the purification box 110 is connected to the tail gas pipe of the incinerator, there is airflow in the purification box 110. In order to prevent the airflow from blowing out the activated carbon in the adsorption chamber 150, the above-mentioned arrangement is made. The brushes 180 can effectively block the activated carbon to prevent it from being blown out. At the same time, during the process of feeding material into the adsorption chamber 150, the uniform distribution pipe 123 can squeeze the brushes 180 to make them bend, so it does not affect the normal feeding.

[0024] In some embodiments, a vibration motor is provided at the bottom of the conical funnel 140, and the vibrating end of the vibration motor abuts against the bottom wall of the conical funnel 140. In this embodiment, by providing a vibration motor to assist the conical funnel 140 in feeding, the activated carbon inside is prevented from becoming clogged or stuck.

[0025] In some embodiments, at least three support rods 131 are vertically fixed below the construction platform 130, and the three support rods 131 penetrate the bottom wall of the conical funnel 140 and are fixedly connected inside the purification box 110. In this application, the construction platform 130 is supported by the support rods 131, thereby ensuring the stability of the equipment during use.
