Description

Technical Field

[0001] This utility model relates to the technical field of slag treatment equipment, specifically to an intelligent control system and curing chamber for carbonization and curing of municipal solid waste incinerator slag. Background Technology

[0002] Municipal solid waste refers to solid waste generated in daily life or in activities that provide services for daily life, as well as solid waste that is considered municipal solid waste according to laws and administrative regulations. The slag after municipal solid waste incineration contains a lot of harmful substances, so it needs to be treated before being discharged. In the process of treating the slag, the organic matter in the slag is further degraded, the heavy metals are stabilized, and its physicochemical properties are improved by simulating the natural carbonization process (or by using artificial accelerated carbonization technology), so that it can be transformed into reusable building materials.

[0003] Existing slag curing bins mostly use horizontal drum furnaces for carbonization curing. The existing curing bins mostly adopt a continuous operation mode, that is, continuous feeding and discharging during the curing process, which requires both ends to remain open. During the curing process, carbon dioxide gas is easy to escape from the openings at both ends, resulting in low carbon dioxide utilization. In addition, the slag is easy to accumulate during the transportation process, and carbon dioxide cannot fully contact the slag, resulting in low carbonization efficiency.

[0004] Therefore, it is necessary to invent an intelligent control system and maintenance chamber for the carbonization and curing of municipal solid waste incinerator slag to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide an intelligent control system and curing chamber for the carbonization and curing of municipal solid waste incinerator slag, in order to solve the problems of low carbon dioxide utilization rate and slag accumulation during transportation, which prevents carbon dioxide from fully contacting the slag and results in low carbonization efficiency.

[0015] By adopting the above technical solution, the stirring motor, the first bevel gear and the second bevel gear work together to drive the rotating tube, the diversion tube and the spiral stirring blade to rotate, so as to stir the slag and make it fully contact and react with carbon dioxide.

[0030] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0031] This utility model provides, for example Figures 1 to 3 The invention relates to an intelligent control system and curing chamber for the carbonization and curing of municipal solid waste incinerator slag. The system includes a curing chamber body 1, a heating cylinder 11 fixedly connected to the side of the curing chamber body 1, an insulation layer 12 fixedly connected to the surface of the heating cylinder 11, multiple sets of support legs 13 fixedly connected to the lower end of the curing chamber body 1, a feed pipe 14 and a discharge pipe 15 fixedly connected to the upper and lower ends of the curing chamber body 1 respectively, pneumatic valves 16 installed on the surfaces of both the feed pipe 14 and the discharge pipe 15, a pressure relief valve 17 installed on the side of the upper end of the curing chamber body 1, a monitoring element 19 installed on the front side of the upper end of the curing chamber body 1, and an air intake agitator inside the curing chamber body 1. The air intake agitator includes a rotating pipe 2, a diversion pipe 21, an exhaust port 22, a spiral agitator 23, a fixing sleeve 24, a rotary joint 25, a first bevel gear 26, an agitator motor 27, a second bevel gear 28, an air intake pipe 3, and a connector 31.

[0032] Among them, the curing chamber 1 is used for slag carbonization curing. During the use process, the slag is first pretreated. After the incinerator slag is discharged from the incinerator, it first enters the slag discharge machine to be cooled to room temperature, and then the waste metal is separated by the magnetic separator. Large particles of impurities are removed by screening, and then the water is washed to reduce the moisture content to obtain slag that meets the carbonization requirements. The slag is then fed into the interior of the curing chamber 1 through the feed pipe 14 by the screw feeder.

[0033] During the carbonization curing process, the pneumatic valve 16 inside the feed pipe 14 is closed to seal the interior of the curing chamber 1. At this time, the air intake agitator is activated to agitate and disperse the slag. Simultaneously, high-concentration carbon dioxide (concentration ≥ 50%) is injected into the interior of the curing chamber 1 through the air intake agitator via the carbon dioxide supply system. Under the action of agitation and carbon dioxide, the slag reacts fully with the carbon dioxide, improving the reaction efficiency. This causes the organic matter in the slag to be oxidized and decomposed, and heavy metals to undergo a carbonation reaction with carbon dioxide.

[0034] After the reaction is complete, the pneumatic valve 16 inside the discharge pipe 15 is opened, and the carbonized slag is sent to the subsequent processing workshop for recycling and reuse via a belt conveyor.

[0035] Meanwhile, during the carbonization curing of the slag, the temperature and carbon dioxide content inside the curing chamber 1 are precisely regulated by an intelligent control system. The temperature, humidity and carbon dioxide monitors in the monitoring unit 19 are used to monitor the temperature, humidity and carbon dioxide content inside the curing chamber 1 in real time and feed the monitoring information back to the control system. The control system controls the heating cylinder 11 and the carbon dioxide supply system to heat the inside of the curing chamber 1 and inject carbon dioxide, so that the temperature inside the curing chamber 1 is maintained between room temperature and 100°C. This avoids the reaction rate being affected by low temperature and the slag sintering being caused by high temperature. At the same time, the carbon dioxide concentration is maintained at 50%-70% to ensure that the carbonation reaction is fully carried out.

[0036] See Figures 2 to 5 A mounting base 18 is fixedly connected to the middle of the upper end of the maintenance chamber 1. A fixing sleeve 24 is fixedly connected to the middle of the rotating tube 2. The fixing sleeve 24 is rotatably connected to the mounting base 18. Two sets of symmetrically distributed diversion pipes 21 are fixedly connected to the side of the rotating tube 2 near the lower side. Multiple sets of exhaust holes 22 are opened on the surface of both the diversion pipe 21 and the rotating tube 2. A spiral stirring paddle 23 is fixedly connected to the lower end of the rotating tube 2. A stirring motor 27 is fixedly installed on the side of the mounting base 18. A second bevel gear 28 is fixedly connected to the output end of the stirring motor 27. A first bevel gear 26 is fixedly connected to the upper end of the fixing sleeve 24. The first bevel gear 26 and the second bevel gear 28 are meshed. A protective cover 29 is provided on the outer side of the first bevel gear 26 and the second bevel gear 28. The lower end of the protective cover 29 is fixedly connected to the surface of the mounting base 18. A rotary joint 25 is fixedly connected to the upper end of the rotating tube 2. A connector 31 is fixedly connected to the left end of the air inlet pipe 3. The connector 31 is rotatably connected to the rotary joint 25.

[0037] Specifically, during the slag gas induction and stirring process, high-concentration carbon dioxide gas is injected into the curing chamber 1 through the inlet pipe 3, rotating pipe 2, and diversion pipe 21 via the carbon dioxide supply system. At the same time, the stirring motor 27 is started. The output end of the stirring motor 27 drives the second bevel gear 28 to rotate. The second bevel gear 28 cooperates with the first bevel gear 26 to drive the rotating pipe 2 to rotate. The rotating pipe 2 drives the diversion pipe 21 and the spiral stirring paddle 23 to rotate. During the rotation of the rotating pipe 2 and the diversion pipe 21, the carbon dioxide gas is evenly dispersed between the slag. The spiral stirring paddle 23 rotates and disperses the slag, so that the slag and carbon dioxide can fully contact and mix.

[0038] The working principle of this utility model is as follows: After the slag enters the curing chamber 1, the pneumatic valve 16 inside the feed pipe 14 is closed to seal the interior of the curing chamber 1, thereby preventing carbon dioxide loss and improving carbon dioxide utilization. Then, the air intake agitator is activated to stir and disperse the slag. At the same time, high-concentration carbon dioxide is injected into the interior of the curing chamber 1 through the air intake agitator. Under the action of stirring and carbon dioxide, the slag and carbon dioxide react fully, improving the reaction efficiency. After the reaction is completed, the pneumatic valve 16 inside the discharge pipe 15 is opened, and the carbonized slag is sent to the subsequent processing workshop for recycling and reuse via a belt conveyor.
