Description

Technical Field

[0001] The utility model relates to the technical field of biogas gasification, in particular to a biogas gasification device. Background Art

[0002] Biomass refers to low-density, renewable agricultural and forestry waste. In the past two decades, the main ways to develop and utilize solid biomass have been "densification molding", "gasification" and "liquefaction", in order to increase energy density and meet the needs of modern production and life. Among them, pyrolysis gasification and dry distillation gasification technologies are widely promoted and applied. Pyrolysis gasification of solid biomass usually uses air as the gasifying agent, and the resulting product is a low-calorific value combustible gas with a gasification efficiency of less than 75%. Dry distillation gasification produces biomass coke and dry distillation gas, with an actual efficiency of only 70%, of which biomass coke accounts for about 40% and dry distillation gas accounts for about 30%. Biocoke needs to be developed again, but small-scale dry distillation gasification stations are small in scale and low in output, making it difficult to achieve high-value-added development of biocoke. Although the combustible gas produced has a high calorific value, its output is limited and it can only be used as energy for daily life on a small scale. Therefore, a biogas gasification device is used to convert biomass.

[0003] Existing technologies include the utility model with publication number CN201292346Y, which discloses a solid biomass vertical combined gasification furnace. The patent adopts a furnace body, a feeding mechanism, a slag discharge mechanism and a transmission mechanism. The furnace body is provided with a dry distillation gasification zone A, a pyrolysis gasification zone B and a secondary cracking gasification zone C; the function of zone A is to dry distill and gasify the solid biomass to generate bio-coke and dry distillation gas; the function of zone B is to pyrolyze and gasify the bio-coke to generate raw fuel gas and ash; the function of zone C is to further crack and gasify the raw fuel gas to generate high-quality fuel gas, while providing the heat required for dry distillation for zone A; the equipment of this utility model solves the problem of the existing problem of arbitrarily discarding biomass and wasting resources.

[0004] In daily work, when the equipment is reacting with biomass, users tend to arbitrarily pour materials into the tank through the material hopper, which easily causes the materials to accumulate at the lower end of the material hopper, making it difficult to evenly spread the materials inside the tank, making it difficult for the equipment to fully react with the accumulated materials. Utility Model Content

[0005] The purpose of the utility model is to solve the shortcomings of the prior art that the material is difficult to be spread flat inside the tank, which makes it difficult for the equipment to fully react the material, and to propose a biogas gasification device.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a biogas gasification device, including a tank body, a bracket, an air inlet pipe, an exhaust pipe, a gas pipe and a feeding device, the surface of the tank body is fixedly connected to the bracket, the side of the tank body is fixedly connected to the air inlet pipe, the side of the tank body is fixedly connected to the exhaust pipe, the upper end of the tank body is fixedly connected to the gas pipe, the feeding device is arranged on the upper surface of the tank body, the feeding device includes a material hopper and a connecting frame, the connecting frame is fixedly connected to the upper surface of the tank body, the material hopper is fixedly connected to the upper surface of the tank body, and the interior of the material hopper is fixedly connected to a limiting frame.

[0007] Furthermore, the internal rotation of the limit frame is connected to a distribution head, and the side of the distribution head is fixedly connected to a baffle. By setting the baffle, the material entering the material hopper can be quickly discharged, which reduces the situation where the material is easily accumulated inside the material hopper when the equipment is in use, making it difficult to quickly discharge the material.

[0008] Furthermore, a positioning frame is fixedly connected to the interior of the connecting frame, and a motor is fixedly connected to the interior of the connecting frame. The motor is provided to facilitate the application of power to the material distributing head.

[0009] Furthermore, the output end of the motor is rotatably connected to the inside of the positioning frame, and the output end of the motor is fixedly connected to the surface of the material distribution head. The positioning frame is provided to facilitate stable operation of the motor.

[0010] Furthermore, a filtering device is provided at the connection between the gas pipe and the tank body, and the filtering device includes a filter box and a connecting plate. The filter box is fixedly connected to the surface of the tank body, the connecting plate is arranged at the upper end of the filter box, and the lower surface of the connecting plate is fixedly connected with a filter plate, the filter plate is arranged with the inner wall of the filter box, and the upper surface of the connecting plate is fixedly connected with a pull handle, and a pull groove is provided on the side of the filter box, and the inner wall of the pull groove is slidably connected with a pull rod. By setting the filter plate, the biogas discharged from the tank body can be filtered, thereby reducing the situation where impurities in the biogas are too high when the equipment is in use, resulting in low purity of the biogas and difficulty in maintaining combustion.

[0011] Furthermore, one end of the pull rod is fixedly connected to a spring, and the end of the spring away from the pull rod is fixedly connected to the inner wall of the pull groove. The spring is provided to facilitate applying a reset elastic force to the pull rod.

[0013] Compared with the prior art, the advantages and positive effects of the present invention are:

[0014] In the present invention, when the device is in use, the user places the biological material into the material hopper, and then the biological material enters the tank body for decomposition, and the generated gas is discharged through the gas pipe. When the device is in use, the user starts the motor, and then the motor rotates to drive the material dividing head to rotate inside the material hopper, and then the material dividing head rotates inside the limit frame. When the material dividing head rotates, it drives the baffle to rotate to discharge the material inside the material hopper. By setting up a discharge device, the material inside the material hopper is effectively discharged, which plays a role in quickly discharging the material inside the material hopper, reducing the problem that when the device is in use, the user generally pours the material into the tank body through the material hopper at will, which easily causes the material to accumulate at the lower end of the material hopper, making it difficult to evenly lay the material inside the tank body, making it difficult for the device to completely react with the accumulated material, thereby improving the practicality of the device.

[0015] In the utility model, a filtering device is provided. When the device is in use, the user moves the barrier rod, and the movement of the barrier rod drives the pull rod to move, and the movement of the pull rod drives the spring to be displaced and deformed to generate elastic force, and the barrier rod moves away from the surface of the connecting plate, and the connecting plate loses its restraint, and the pull handle is pulled to drive the connecting plate to move and drive the filter plate to move away from the inside of the filter box. By providing the filtering device, the gas discharged from the inside of the device is effectively filtered, which plays a role in removing impurities in the biogas, reduces the risk of a large amount of impurities in the biogas due to incomplete reaction inside the device when the device is in use, affects the purity of the biogas, and causes the biogas to be of low purity and difficult to burn, thereby improving the practicality of the device.
