Description

Technical Field

[0001] The present invention relates to the technical field of environmental engineering, and particularly to a household perishable garbage disposal device and a method for using the same.

Background Art

[0002] Household perishable garbage usually refers to organic solid waste generated in the daily life of urban residents, mainly including kitchen waste, gardening waste, human and animal feces, etc.

[0003] Perishable garbage has the following hazards. When deposited outdoors, harmful gases such as ammonia and sulfides are released, polluting the atmosphere and the urban living environment. The high-concentration leachate generated during the deposition and decay process seriously pollutes water areas. Harmful organisms such as pathogenic microorganisms, mosquitoes, flies, cockroaches and rats are likely to breed, affecting the health of residents. It invades a large amount of land. It may cause accidents such as garbage explosions. Therefore, if urban organic waste is not effectively treated, it will bring serious hazards to the lives of residents and the ecological environment, and it is necessary to attract the attention of all aspects.

[0004] The main conventional treatment modes for perishable waste mainly use the centralized treatment mode, that is, the domestic waste within the urban area is uniformly collected, transported to the centralized treatment plant for treatment. Common methods include composting treatment, incineration treatment, pyrolysis treatment, landfill treatment, and biological treatment, etc. However, the existing centralized treatment methods still need to be further improved. For example, composting treatment has the disadvantages of relatively low treatment efficiency, unstable treatment process due to different waste compositions, and large land occupation area. Incineration treatment is prone to generating secondary pollutants such as dioxins and causes waste of resources. Pyrolysis treatment has the disadvantages of high operation specialization and limited means of recycling existing products. Landfill treatment has the disadvantages of large land occupation area and high cost of disposal and transportation. The biological treatment processes using American earthworms, earthworms, microbial anaerobic fermentation, etc. have the disadvantages of relatively low conversion efficiency, great influence from the environment such as climate, and large land occupation area.

[0005] On the other hand, with the gradual popularization and implementation of waste separation in urban and rural areas, there are requirements for separate collection, separate transportation, and separate treatment of perishable waste such as separated domestic waste and garden waste. An independent organic waste collection and transportation system is huge, complex, costly, and has many problems. These problems are particularly serious in small and medium-sized county cities with low population density and low waste generation intensity. At present, there is still room for improvement in the separate treatment technology of separated organic waste. Therefore, while residents separate waste at the source, the waste collection and treatment departments will collect and treat the separated waste in a mixed manner, greatly frustrating the enthusiasm of residents to implement waste separation and delaying the popularization and implementation of waste separation.

[0006] Due to the existence of the above problems, it is objectively required to disperse and process perishable garbage at the source of generation, that is, to classify and effectively process garbage at the source in units such as households. This can not only solve the problems such as separate transportation and separate treatment currently faced after the separate collection of garbage, but also realize the recycling and utilization of products at the source of generation, thereby reducing the energy consumption in the processes such as the collection of centralized treatment, the recycling and utilization distribution of products after centralized treatment, etc., reducing the treatment cost, and having a significant effect on reducing carbon emissions, with remarkable social and environmental benefits.

[0007] Currently, the organic waste decentralized treatment technologies commonly used at home and abroad include food waste crushing treatment technology, household composting treatment technology, earthworm reactors, water evaporation treatment devices, small pyrolysis devices, etc. Among them, the small pyrolysis decentralized treatment device for organic waste has advantages such as high treatment efficiency, relatively stable process, and high resource value of biochar as a pyrolysis product, so it is valued by people. However, overall, the household pyrolysis process and device still have disadvantages such as insufficient support from basic technical theories and insufficient design and development capabilities of the device, and it is necessary to urgently develop new treatment devices.

[0027] In this specific embodiment, the crushing housing is made of heat-resistant plastic, and the crushing housing has a rectangular parallelepiped structure with a length, width, and height of 25 cm × 30 cm × 30 cm. After opening the cover plate, the crushing device 1-3 can be installed. The crushing device 1-3 includes a crushing blade, a blade mounting rod, and a top mounting head. The crushing blade is installed on the outer wall of the blade mounting rod, and the top mounting head is installed at the top of the blade mounting rod. The top mounting head is used to connect to the driving device. The crushing blade is a propeller-shaped stainless steel blade with a total length of 10 cm at the bottom. The crushing blade mounting rod is a stainless steel rod with a diameter of 10 mm and a height of 15 cm. The top mounting head is connected to the power supply, and the crushing blade can be rotated to cut and crush perishable garbage. The crushing device basket 1-2 is made of stainless steel with a diameter of 20 cm and a height of 17 cm. Round holes with a diameter of 0.5 cm are evenly opened on the surface at intervals of 3 cm. After the blade of the crushing device 1-3 is installed and fixed, it is located in the center of the crushing device basket 1-2. The crushing device basket 1-2 is suspended in the crushing unit 1 with a hook.

[0028] After installing the crushing basket and the crushing device 1-3, put perishable garbage into the basket, close the cover plate, let the cooling water flow, start the crushing device 1-3 to crush. The cooling water supply pipe 1-1 has a diameter of 2 cm and is connected to the household tap water faucet. Its water outlet is located above the crushing device basket 1-2. The cooling water sprays and enters along the tangential direction of the blade rotation, playing the role of cooling and cleaning.

The cooling water and penetration liquid discharge port 1-5 has a diameter of 2 cm, and the lower part is directly connected to the sewer pipe with a plastic hose.

[0029] The pyrolysis housing is manufactured from heat-resistant plastic. An openable cover plate is installed at the top of the pyrolysis housing. The pyrolysis housing has a cuboid structure with a length, width, and height of 10 cm × 30 cm × 30 cm. Inside the pyrolysis housing, heat-insulating cotton is lined. The upper cover plate of the pyrolysis unit 2 is openable and is used to place or remove the pyrolysis device basket 2-1. The pyrolysis device basket 2-1 has a cuboid net-bag structure with a length, width, and height of 9 cm × 28 cm × 28 cm, with a hollow top and sealed surroundings and bottom. The net bag is made of a stainless steel wire mesh with a hole diameter of 5 mm. In the pyrolysis unit 2, a solid heat medium 2-2 is arranged, and the solid heat medium 2-2 is sand with a particle size of less than 2 mm.

[0030] After the perishable garbage is crushed in the crushing unit 1, the crushing device basket 1-2 can be taken out, and the crushed perishable garbage in the crushing basket is poured into the pyrolysis basket. Next, after fixing the pyrolysis device basket 2-1 to the pyrolysis unit 2 with a hook, the solid heat medium 2-2 is filled around it so as to fully wrap the surroundings of the crushed perishable organic garbage with the solid heat medium 2-2. Then, the cover plate of the pyrolysis unit 2 is closed, the heating plate 2-4 is activated, the temperature is raised to a certain degree and maintained for a certain time, and the perishable organic garbage is fully pyrolyzed. The heating plate 2-4 is attached to the bottom of the pyrolysis unit 2 and is composed of a stainless steel plate with a length, width, and thickness of 9 cm × 28 cm × 1 cm and containing heating wires. During the pyrolysis process, after the upper cover plate of the pyrolysis unit 2 is closed, the pyrolysis gas is discharged from the pyrolysis unit 2 only through the pyrolysis unit exhaust port 2-3. The pyrolysis unit exhaust port 2-3 is a heat-resistant plastic round pipe with a diameter of 3 cm, with a length of 2 cm inside the pyrolysis unit 2 and is wrapped with a mesh cover outside. The pyrolysis unit exhaust port 2-3 is connected in communication with the pyrolysis gas pipeline 3-1 in the condensation cleaning unit 3, and the generated gas is discharged from the pyrolysis unit exhaust port 2-3 to the pyrolysis gas pipeline 3-1.

[0031] After the pyrolysis is completed, the pyrolysis unit basket 2-1 is taken out from the pyrolysis unit 2. Due to the action of gravity, the solid heat medium 2-2 with a particle size smaller than the mesh diameter of the pyrolysis unit basket 2-1 falls from the basket, and the pyrolyzed biochar 2-5 with a particle size larger than 5 mm after pyrolysis is blocked by the basket and taken out from the device.

[0032] The condensation housing is made of heat-resistant plastic, and the condensation cleaning unit 3 has a cubic structure with a length, width, and height of 30 cm × 30 cm × 30 cm. While pyrolysis is carried out, the condensation device 3-3 is opened to condense and clean the pyrolysis gas. That is, the pyrolysis gas generated in the pyrolysis unit 2 enters the pyrolysis gas pipeline 3-1 from the pyrolysis unit exhaust port 2-3 under the action of heating and pressurization. The pyrolysis gas pipeline 3-1 is made of heat-resistant plastic with a diameter of 3 cm, and its exhaust port is connected to the condensation device 3-3. The condensation device 3-3 is a cylindrical glass condensation tube with a diameter of 5 cm and a length of 20 cm. Inside it is a glass gas pipeline with a diameter of 2 cm. The external cylindrical annular sealed cavity is the inlet and outlet space for cooling water. The condensation device 3-3 is connected to a water pipe, and cooling water is provided from the water pipe.

[0033] After the pyrolysis gas enters the condensation device 3-3, under the action of the cooling water in the condensation device 3-3, a part of the components is cooled and enters the condensate receiver. The condensate receiver is a conical glass bottle with a height of 8 cm and a diameter of 6 cm. A residual exhaust gas discharge pipeline 3-5 is opened on its side. The residual exhaust gas enters the exhaust gas absorption and cleaning device 3-6 after passing through the condensate receiver 3-4. The exhaust gas absorption and cleaning device 3-6 is a cylindrical glass container with a diameter of 10 cm and a height of 8 cm. Inside it, tap water accounting for 80% of the volume is contained. After the exhaust gas is absorbed by the cleaning liquid and deodorized, it enters the condensation cleaning unit 3 and is discharged from the device through the condensation cleaning unit exhaust port 3-2. The condensation cleaning unit exhaust port 3-2 is a plastic pipe with a diameter of 3 cm.

[0034] Example 2: The present invention further discloses a method for using a household perishable waste treatment device based on Example 1. First, crush the perishable organic waste. The user puts the perishable organic waste generated in the household into the crushing device basket 1-2, closes the cover plate at the top of the crushing housing, allows cooling water to flow, starts the crushing device 1-3, and crushes the perishable organic waste to a certain extent. The cooling water and the waste infiltration liquid are discharged into the sewage pipe network through the cooling water and infiltration liquid discharge port 1-5. Next, pyrolyze the crushed perishable organic waste. The user takes out the crushing device basket 1-2, pours the crushed perishable organic waste into the pyrolysis device basket 2-1. After placing the pyrolysis device basket 2-1 in the pyrolysis unit 2, fill the solid heat medium 2-2 so as to fully wrap the surroundings of the crushed perishable organic waste. Then, close the cover plate at the top of the pyrolysis housing, start the heating plate 2-4, raise the temperature to a certain extent and maintain it for a certain time, and the perishable organic waste is fully pyrolyzed. The gas generated during the pyrolysis process is discharged from the pyrolysis unit exhaust port 2-3 into the pyrolysis gas pipeline 3-1. Utilizing the structural features of the pyrolysis device basket 2-1, the solid heat medium 2-2 can be sieved and separated, and the pyrolysis biochar 2-5 can be collected regularly. At the same time as pyrolysis, open the condensation washing unit 3 to condense and collect the low-boiling pyrolysis liquid in the pyrolysis gas, and treat the gas components that cannot be condensed with the exhaust gas absorption and washing device 3-6 and discharge them from the device.
