Description

Technical Field

[0001] This utility model relates to the technical field of chemical waste treatment equipment, and in particular to an anaerobic pyrolysis carbonization furnace for chemical waste salt. Background Technology

[0002] Chemical production processes generate large quantities of waste salt containing organic pollutants. Direct discharge of this waste salt can severely pollute soil, water bodies, and other ecological environments, while also wasting salt resources. Anaerobic pyrolysis carbonization furnaces utilize an oxygen-free environment to prevent the reaction between salt and oxygen, thus avoiding the formation of impurities. Precise temperature control prevents the salt from melting, agglomerating, or decomposing, ultimately producing "clean salt" with extremely low organic pollutant content, meeting industrial reuse standards (such as for process water replenishment, auxiliary raw materials, etc.), achieving "waste resource utilization" and reducing the need for new salt extraction.

[0003] In existing anaerobic pyrolysis carbonization furnaces, waste salt is usually directly introduced into the pyrolysis carbonization chamber during use. The lack of an effective dispersing structure to break up the agglomerated waste salt makes it difficult for heat to penetrate in time, resulting in incomplete decomposition of organic pollutants. Utility Model Content

[0004] The purpose of this invention is to solve the problem in the existing technology of anaerobic pyrolysis carbonization furnaces where waste salt is usually directly introduced into the pyrolysis carbonization chamber without an effective dispersing structure to break up the agglomerated waste salt, resulting in heat not being able to penetrate in time and thus causing incomplete decomposition of organic pollutants. Therefore, an anaerobic pyrolysis carbonization furnace for chemical waste salt is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a chemical waste salt anaerobic pyrolysis carbonization furnace, comprising a carbonization furnace assembly, wherein a crushing assembly and an adsorption assembly are provided on the top of the carbonization furnace assembly, the carbonization furnace assembly includes a carbonization furnace body, a heating structure is provided on the carbonization furnace body, the crushing assembly includes a crushing box, crushing rollers are symmetrically arranged inside the crushing box, one end of the crushing rollers is connected to a rotating motor, a tilting motor is connected to the side of the crushing box, a cover plate is connected to the output end of the tilting motor, and a sealing frame is provided inside the crushing box.

[0006] Preferably, the adsorption assembly includes an adsorption box, the bottom of which is connected to the carbonization furnace body via a pipe, and multiple activated carbon boxes are distributed inside the adsorption box.

[0007] Preferably, a stirring motor is connected to one end of the carbonization furnace body, a drive shaft is installed inside the carbonization furnace body, and multiple stirring scrapers are distributed on the outer side of the drive shaft.

[0008] Preferably, a furnace door is installed at the other end of the carbonization furnace body, a fastener is installed on the side of the furnace door, a limit frame is installed on the carbonization furnace body, and the fastener is set on the limit frame.

[0011] Preferably, an oxygen-free gas inlet is connected to the side of the carbonization furnace body, and a support frame is installed at the bottom of the carbonization furnace body.

[0012] Preferably, the crushing box is located at the top of one end of the carbonization furnace body, and the adsorption box is located at the top of the other end of the carbonization furnace body.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, the crushing rollers are driven by a rotating motor to rotate, causing the two crushing rollers to rotate in opposite directions. This helps to break up the agglomerated waste salt, reducing the amount of agglomerated waste salt entering the interior of the carbonization furnace body. It also promotes full contact between the waste salt and the internal heat and oxygen-free protective gas of the carbonization furnace body, improving the pollutant removal effect and increasing the processing efficiency. The cover plate is driven by a rotating motor to rotate, which helps to rotate the cover plate. This, combined with the sealing frame, improves the sealing performance during the pyrolysis treatment of the carbonization furnace body.

[0015] 2. In this utility model, the fan operates and opens the valve to draw gas from inside the carbonization furnace body, allowing the gas to enter the adsorption box. The activated carbon box is beneficial for adsorbing and treating particulate matter and harmful substances in the gas, reducing the direct emission of harmful substances, lowering the amount of harmful substances emitted, protecting the environment, and reducing air pollution.

[0023] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0024] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0025] Example 1: As Figures 1-6As shown, this utility model provides a technical solution: an anaerobic pyrolysis carbonization furnace for chemical waste salt, including a carbonization furnace assembly 1. A crushing assembly 2 and an adsorption assembly 3 are arranged on the top of the carbonization furnace assembly 1. The carbonization furnace assembly 1 includes a carbonization furnace body 101, on which a heating structure 107 is arranged. The crushing assembly 2 includes a crushing box 201, inside which crushing rollers 203 are symmetrically arranged. One end of each crushing roller 203 is connected to a rotating motor 202, and a tilting motor 20 is connected to the side of the crushing box 201. 4. The output end of the flipping motor 204 is connected to a cover plate 205. The inside of the crushing box 201 is equipped with a sealing frame 206. One end of the carbonization furnace body 101 is connected to a stirring motor 106. A drive shaft 108 is installed inside the carbonization furnace body 101. Multiple stirring scrapers 109 are distributed on the outside of the drive shaft 108. A furnace door 104 is installed at the other end of the carbonization furnace body 101. A fastener 105 is installed on the side of the furnace door 104. A limit frame is installed on the carbonization furnace body 101. The fastener 105 is set on the limit frame.

[0026] In this embodiment, by connecting the discharge port of the conveying structure to the crushing box 201, the feeding of waste salt is facilitated. The rotating motor 202 electrically drives the crushing rollers 203 to rotate, causing the two crushing rollers 203 to rotate in opposite directions. This helps to break up agglomerated waste salt, reducing the amount of agglomerated waste salt entering the carbonization furnace body 101. It also ensures that the waste salt fully contacts the heat and oxygen-free protective gas inside the carbonization furnace body 101, improving the pollutant removal effect and processing efficiency. The rotating motor 204 electrically drives the cover plate 205 to rotate, which in turn facilitates the flipping of the cover plate 205, further improving the process within the carbonization furnace body 101. During pyrolysis, the sealing frame 206 improves the sealing performance. The heating structure 107 on the carbonization furnace body 101 facilitates the pyrolysis treatment inside the carbonization furnace body 101. The oxygen-free gas inlet 103 facilitates the entry of oxygen-free gas into the interior of the carbonization furnace body 101. The stirring motor 106 electrically drives the transmission shaft 108 to rotate, which in turn drives the stirring scraper 109 to rotate, which facilitates the stirring treatment of the waste salt inside the carbonization furnace body 101. This increases the contact area between the waste salt and the interior of the carbonization furnace body 101, accelerates the pyrolysis reaction process, and improves the pyrolysis reaction rate of the waste salt.

[0027] Example 2: As Figures 1-6As shown, the adsorption assembly 3 includes an adsorption box 301. The bottom of the adsorption box 301 is connected to the carbonization furnace body 101 via a pipe. Multiple activated carbon boxes 305 are distributed inside the adsorption box 301. An exhaust pipe 302 is connected to the top of the adsorption box 301. A valve 303 is installed at the bottom of the adsorption box 301. A fan 304 is installed inside the adsorption box 301. A side plate 306 is installed on the side of the adsorption box 301. An oxygen-free gas inlet 103 is connected to the side of the carbonization furnace body 101. A support frame 102 is installed at the bottom of the carbonization furnace body 101. A crushing box 201 is located at the top of one end of the carbonization furnace body 101, and the adsorption box 301 is located at the top of the other end of the carbonization furnace body 101.

[0028] In this embodiment, after the pyrolysis reaction inside the carbonization furnace body 101 is completed and cooled, the fan 304 operates and the valve 303 is opened to draw the gas inside the carbonization furnace body 101, allowing the gas to enter the adsorption box 301. The activated carbon box 305 is beneficial for adsorbing and treating particulate matter and harmful substances in the gas, reducing the direct emission of harmful substances, lowering the amount of harmful substances emitted, which is beneficial for environmental protection and reducing air pollution. With the cooperation of the side plate 306, it is easy to open the adsorption box 301 to maintain and replace the activated carbon box 305 inside.

[0029] The working principle of this embodiment is as follows: In use, the discharge port of the conveying structure is first connected to the crushing box 201 to facilitate waste salt feeding. The crushing rollers 203 are electrically driven to rotate by the rotating motor 202, causing the two crushing rollers 203 to rotate in opposite directions, which helps to break up the clumps of waste salt and reduces the amount of clumps entering the carbonization furnace body 101. After feeding is completed, the cover plate 205 is electrically driven to rotate by the tilting motor 204, which in turn helps to tilt the cover plate 205. This, combined with the sealing frame 206, improves the sealing performance during the pyrolysis treatment of the carbonization furnace body 101. Then, the oxygen-free gas inlet 103 facilitates the entry of oxygen-free gas into the carbonization furnace body 101. The heating structure 107 on the carbonization furnace body 101 further enhances the heating effect on the carbonization furnace body. The carbonization furnace body 101 undergoes pyrolysis treatment, while the drive shaft 108 is electrically driven by the stirring motor 106 to rotate, which in turn drives the stirring scraper 109 to rotate. This facilitates the stirring of the waste salt inside the carbonization furnace body 101, increasing the contact area between the waste salt and the interior of the carbonization furnace body 101 and accelerating the pyrolysis reaction process. After the pyrolysis reaction inside the carbonization furnace body 101 is completed and cooled, the fan 304 operates and the valve 303 is opened to extract the gas inside the carbonization furnace body 101, allowing the gas to enter the adsorption box 301. The activated carbon box 305 is used to adsorb particulate matter and harmful substances in the gas, reducing the direct emission of harmful substances. Finally, the side plate 306 facilitates the opening of the adsorption box 301 to maintain and replace the activated carbon box 305 inside.

Their working principles are known technologies. The appropriate model is selected according to actual use. Therefore, the stirring motor 106, heating structure 107, rotating motor 202, tilting motor 204, and fan 304 will not be explained in detail.
