Description

Technical Field

[0001] The invention relates to the technical field of solid waste fermentation treatment, and in particular to a solid waste disposal fermentation box system. Background Art

[0002] A large amount of solid waste is generated in daily life and production. For the treatment of this type of solid waste, there is a technology that uses microbial fermentation in a fermentation box to decompose the substances to obtain some recyclable components, while reducing pollution and damage to the environment and speeding up the treatment efficiency of solid waste.

[0003] In existing fermentation boxes, solid waste is generally placed in a closed cavity. During the microbial fermentation process, the solid waste is decomposed into multiple components, and finally a substance that can be processed later is obtained. This process can minimize the pollution and damage to the environment and improve the recycling of substances. However, a large amount of gaseous substances generated in the process, such as CO2, CH4, NH3, H2S and other gases generated by the decomposition of some solid waste, are not specifically recycled or utilized, but are generally directly discharged to the outside, resulting in environmental pollution and waste of resources.

[0004] It can be seen that the current fermentation box still has room for improvement. It should be adjusted and optimized to recycle the gas produced by decomposition, improve the treatment degree of solid waste fermentation products, reduce pollution and damage to the environment, and promote the recycling of materials. Therefore, it is necessary to propose a more reasonable technical solution to solve the technical problems existing in the existing technology. Summary of the invention

[0005] In order to overcome at least one of the defects mentioned above, the present invention proposes a solid waste disposal fermentation box system, which promotes the recovery and treatment of gases generated by the decomposition of solid waste by adjusting and optimizing the fermentation box structure, helps to improve the degree of material treatment, reduces waste gas emissions, and thus reduces damage to the environment.

[0006] In order to achieve the above purpose, the fermentation box system disclosed in the present invention can adopt the following technical solutions:

[0007] A solid waste disposal fermentation box system includes a fermentation box, in which a gas recovery component is arranged, the gas recovery component includes a plurality of recovery pipes, the recovery pipes are staggered above the stacking fermentation area in the fermentation box and are provided with a plurality of air intakes; the gas recovery component also includes an air guide channel, which extends from the inside to the outside of the fermentation box and is used to transport the gas transported by the recovery pipe to the outside of the fermentation box; the air guide channel is also connected to a purification box for purifying the gas.

[0008] The fermentation box system disclosed above uses the temperature and humidity control system in the fermentation box to cooperate with the growth of microorganisms to ferment the materials to achieve the degradation of the substances, thereby effectively treating the solid waste. The waste gas generated in the process is recovered and treated by the gas recovery component, thereby reducing pollution and damage to the environment. The waste gas can be used as other industrial raw material gas after treatment, which improves the recycling rate of the substances and saves natural resources.

[0009] Furthermore, the structure of the recovery pipe is not limited to a single one, and it can be constructed in various forms. Here, an optimization is made and one feasible option is proposed: the recovery pipes are arranged in a staggered manner on a horizontal plane, and the recovery pipes are connected to the air guide channel through a collecting hose. When such a solution is adopted, the recovery pipe collecting hose uniformly transports the gas of all the air guide channels to the external purification box, and the collecting hose is a flexible structure, which is convenient for matching with the air guide channel and achieving sealing.

[0010] Furthermore, in the present invention, the recovery pipe can be arranged in a variety of forms, which are not limited to the only one. Here, an optimization is made and one feasible option is proposed: a support structure is fixedly arranged on the inner wall of the fermentation box, and the support structure cooperates with the recovery pipe and is used to support the recovery pipe. When such a solution is adopted, the support structure can be made of materials such as plastic and corrosion-resistant alloy.

[0011] Furthermore, the support structure can be specifically constructed in a variety of forms, which are not limited to a single form. Here, an optimization is made and one of the feasible options is proposed: the support structure includes a fixed frame fixedly connected to the fermentation box, and a plurality of lifting connection seats are arranged on the fixed frame; the lifting connection seat includes a fixed seat matched with the fixed frame, and also includes a lifting seat that is lifted relative to the fixed seat, and the lifting seat is connected to the recovery pipe and drives the lifting pipe to rise and fall synchronously. When such a scheme is adopted, the fixed frame may include a plurality of connecting columns and a connecting beam arranged on the connecting columns, and the lifting seat is fixed to the connecting beam; the lifting seat is matched with the connecting beam through fasteners, and the matching position with the connecting beam can be adjusted according to the actual structure.

[0012] Furthermore, the lifting seat can be adjusted longitudinally, the purpose of which is to adjust the height of the recovery pipe, and the gas absorption efficiency can be improved for different fermentation materials and different waste gas conditions. Therefore, lifting and lowering can be achieved through a variety of schemes, and its structure is not limited to a single one. Here, it is optimized and one of the feasible options is proposed: the lifting seat and the fixed seat are slidably matched through a polygonal slide groove structure, the lifting seat is provided with a threaded hole, and the fixed seat is provided with a threaded drive rod that matches the threaded hole. When the threaded drive rod rotates, the lifting seat is driven to lift and lower through the threaded match. When such a scheme is adopted, the threaded drive rod can be driven by a servo motor.

[0013] Furthermore, in order to keep the microorganisms alive in the fermentation box and facilitate the stable fermentation, it is necessary to meet the air exchange between the inside and outside of the fermentation box, but at the same time, it is necessary to avoid the leakage of harmful gases generated inside the fermentation box. Therefore, the structure of the fermentation box is optimized, and one of the feasible options is proposed here: a permeable membrane component is also provided above the recovery pipe. When such a solution is adopted, the permeable membrane component can keep the external air from entering the fermentation box, and the moisture in the fermentation box can pass through the permeable membrane to reach the outside of the fermentation box, and the recovery pipe below the permeable membrane component can absorb the generated waste gas in time to prevent the waste gas from directly passing through the permeable membrane to reach the outside of the fermentation box.

[0014] Furthermore, after the waste gas reaches the purification box through the air guide channel, it is treated by the purification structure in the purification box to obtain relatively clean gas. Specifically, it can be treated through a variety of schemes, which are not limited to the only one. Here, it is optimized and a feasible option is proposed: the purification box includes a number of processing parts connected in sequence, including a microbial processing part, a corrosive gas processing part and an adsorption processing part. When such a scheme is adopted, the microbial processing part provides the initial treatment through the growth of microorganisms, the corrosive gas processing part is provided with a corrosion-resistant structure, which can adsorb and react the corrosive gas in the gas, and the adsorption processing part is provided with highly adsorbable substances such as activated carbon to adsorb and treat some substances in the waste gas.

[0015] Furthermore, in the present invention, the reaction efficiency of the material in the fermentation box is related to its physical size. In order to improve the reaction rate, an optimized option is proposed here: the fermentation box is connected to a crushing component and solid waste is obtained from the crushing component; the crushing component includes a crushing box, the crushing box is connected to a feed pipe and a discharge pipe, the feed pipe extends downward from the feed port and connects to the crushing box, and a material screening structure is formed in the discharge pipe. The material that meets the standards after screening by the material screening structure is sent to the fermentation box by the conveying component, and the material that does not meet the standards after screening by the material screening structure is returned to the crushing box by the return pipe for further crushing. When such a scheme is adopted, the solid waste is crushed by the crushing box, and the physical materials that meet the crushing size are selected and enter the fermentation box for further processing, and the materials that do not meet the standards continue to be processed. The screening process is automatically realized in the transportation of materials without consuming separate energy, so it can improve the processing efficiency of the entire fermentation box and make the treatment of solid waste gas more thorough.

[0016] Furthermore, the arrangement of the discharge pipe is not limited to a single one. Here, an optimization is made and one of the feasible options is proposed: the discharge pipe is inclined upward, the screening structure includes a conveyor arranged in the discharge pipe, a drop structure is arranged at the conveyor and is used to screen the qualified materials and drop them to the conveying assembly, and the end of the discharge pipe is connected to the return pipe and the unqualified materials are sent to the return pipe. When such a scheme is adopted, the drop structure is used to screen the materials that meet the standard size. When the size of the materials is too large, they cannot reach the conveying assembly through the drop structure, so they will enter the return pipe and be sent back to the crushing box for further crushing.

[0017] Furthermore, the falling structure can be constructed in various forms, and its structure is not limited to a single one. Here, an optimization is made and one of the feasible options is proposed: the falling structure includes a mesh plate, and a collecting hopper is arranged below the mesh plate, and the discharge port of the collecting hopper extends to the conveying component. When such a scheme is adopted, the mesh plate can be a straight plate or a curved plate; when a scraper conveyor is adopted, the mesh plate is a straight plate and cooperates with the scraper; when an auger conveyor is adopted, the mesh plate is a curved plate and cooperates with the auger.

[0018] Compared with the prior art, some beneficial effects of the technical solution disclosed in the present invention include:

[0019] The present invention improves the degradation and utilization of substances by fermenting solid waste, wherein the generated waste gas is absorbed and treated, thereby preventing the generated waste gas from reaching the outside of the fermentation box and causing environmental pollution and damage, thereby improving the solid waste treatment effect of the fermentation box and improving the recycling rate of substances.

[0036] In order to keep the microorganisms alive in the fermentation box 2 and facilitate the stable fermentation, it is necessary to meet the air exchange between the inside and outside of the fermentation box 2, but at the same time, it is necessary to prevent the harmful gases generated inside the fermentation box 2 from leaking out.

[0038] After the waste gas reaches the purification box 6 through the air guide channel 5, it is processed by the purification structure in the purification box 6 to obtain relatively clean gas.
