Description

Technical Field

[0001] The present invention relates to a superheated steam treatment device, and in particular to a kitchen waste treatment device utilizing superheated steam. Background Art

[0002] With the improvement of living standards and the acceleration of urbanization, the amount of food waste generated is increasing. Food waste has high moisture content, is easily perishable, and emits odors. If not promptly and effectively treated, it will not only cause serious environmental pollution but also affect residents' quality of life and health. Therefore, the development of efficient and environmentally friendly food waste treatment equipment is of great practical significance. Traditional food waste treatment methods mainly include landfill, incineration, and composting, but each has certain limitations. Landfilling requires a large amount of land resources and may cause groundwater and soil pollution. Furthermore, the landfill process of food waste produces a large amount of greenhouse gases, such as methane, which has a negative impact on the environment. Incineration treatment requires high investment and operating costs, and the incineration process produces harmful substances such as dioxins, which pollute the atmospheric environment. In addition, the high moisture content of kitchen waste will reduce incineration efficiency and increase energy consumption; as for composting treatment, although resources can be recycled, the composting process takes a long time, and the quality of compost products is unstable, and there may be problems such as excessive heavy metals. These problems have directly led to the limitation of kitchen waste treatment devices on the market and the inability to form a more mature market.

[0003] To address these issues, the present invention utilizes superheated steam treatment technology. The high temperature of superheated steam rapidly kills pathogens such as bacteria, viruses, and parasites in food waste, effectively preventing the spread of disease. Furthermore, superheated steam rapidly evaporates moisture from food waste, generating no secondary pollution during the process, thus meeting environmental protection requirements. Furthermore, superheated steam can be recycled, reducing energy consumption. Summary of the Invention

[0004] The present invention relates to a kitchen waste treatment device that utilizes superheated steam. This steam is used to dry and carbonize kitchen waste, and combined with gasification, it removes organic pollutants from the waste. Furthermore, the device is compact and can be installed in a wider range of locations. Compared with traditional kitchen waste treatment methods, the device offers advantages such as reduced secondary pollution, lower transportation costs, and the ability to recycle waste products.

[0005] The technical solutions adopted to achieve the above objectives are:

[0006] It mainly includes a water mist channel 1, a steam generator 2, an atomizing nozzle 3, a carbonization reaction chamber 4, and a heat preservation cover 5, and is characterized in that: the atomizing nozzle 3 is installed at one end of the water mist channel 1, and the steam generator 2 is installed at the other end; the steam generator 2 is located inside the carbonization reaction chamber 4, and the end of the steam generator 2 not connected to the water mist channel 1 is facing the kitchen waste inlet 402 located at the entrance position of the carbonization reaction chamber 4; and a heat preservation cover 5 is installed outside the carbonization reaction chamber 4.

[0007] Furthermore, the steam generator 2 is provided with spiral guide vanes 201 to increase the passage time of the water mist inside the steam generator 2, thereby increasing the heating time and effectively increasing the steam temperature.

[0008] Furthermore, a guide vane 401 is provided inside the carbonization reaction chamber 4, which can support the steam generator 2 on the one hand, and provide rotation for the flow inside the carbonization reaction chamber 4 on the other hand, thereby increasing the reaction time of the material inside the carbonization reaction chamber 4. The steam passing through the steam generator 2 can reach 1000-1200°C, which is superheated steam.

[0009] Furthermore, the atomizing nozzle 3 includes a gas inlet 301, a clean water inlet 302 and a nozzle 303; high-speed gas is sprayed in from the gas inlet 301, driving the clean water flowing out of the clean water inlet 302 to pass through the nozzle 303 and become water mist; the high-speed gas sprayed in from the gas inlet 301 provides kinetic energy for the internal flow of the entire superheated steam kitchen waste treatment device.

[0010] Furthermore, the heating device 202 of the steam generator 2 adopts a multi-stage heating series form.

[0011] Furthermore, a grinder is installed upstream of the kitchen waste inlet 402 for crushing the kitchen waste; when the ground kitchen waste enters the carbonization reaction chamber 4 through the kitchen waste inlet 402, it comes into contact with the superheated steam generated in the steam generator 2 to achieve drying and preliminary carbonization, and is blown upward by the superheated steam and floats toward the downstream direction of the carbonization reaction chamber 4.

[0012] Furthermore, the lower end of the carbonization reaction chamber 4 is a streamlined structure, which reduces the momentum loss of the superheated steam generated in the steam generator 2 after entering the carbonization reaction chamber 4.

[0013] The beneficial effects of the present invention are:

[0014] 1. The kitchen waste treatment device using superheated steam described in the present invention adopts an integrated design and has a smaller volume. Compared with traditional waste treatment devices, it can be used in more occasions and reduces transportation costs.

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but the protection scope of the present invention is not limited thereto.

[0022] Figures 1 and 2 The present invention relates to a kitchen waste treatment device using superheated steam and a related structural schematic diagram, which mainly includes a water mist channel 1, a steam generator 2, an atomizing nozzle 3, a carbonization reaction chamber 4, and a heat preservation cover 5. The characteristics are: the atomizing nozzle 3 is installed at one end of the water mist channel 1, and the steam generator 2 is installed at the other end; the steam generator 2 is located inside the carbonization reaction chamber 4, and the end of the steam generator 2 not connected to the water mist channel 1 is opposite to the kitchen waste inlet 402 located at the inlet position of the carbonization reaction chamber 4; the heat preservation cover 5 is installed outside the carbonization reaction chamber 4.

[0023] The steam generator 2 is provided with spiral guide vanes 201 to increase the time for the water mist to pass through the steam generator 2, thereby increasing the heating time and effectively increasing the steam temperature.

[0024] The carbonization reaction chamber 4 is provided with a guide vane 401, which can support the steam generator 2 on the one hand, and provide rotation for the flow inside the carbonization reaction chamber 4 on the other hand, thereby increasing the reaction time of the material inside the carbonization reaction chamber 4. The steam passing through the steam generator 2 can reach 1000-1200°C, which is superheated steam.

[0025] The atomizing nozzle 3 includes a gas inlet 301, a clean water inlet 302 and a nozzle 303; high-speed gas is injected into the gas inlet 301, driving the clean water flowing out of the clean water inlet 302 to pass through the nozzle 303 and turn into water mist; the high-speed gas injected into the gas inlet 301 provides kinetic energy for the internal flow of the entire superheated steam kitchen waste treatment device.

[0026] The heating device 202 of the steam generator 2 adopts a multi-stage heating series form.

[0027] A grinder is installed upstream of the kitchen waste inlet 402 for crushing the kitchen waste. When the ground kitchen waste enters the carbonization reaction chamber 4 through the kitchen waste inlet 402, it comes into contact with the superheated steam generated in the steam generator 2 to achieve drying and preliminary carbonization. Driven by the superheated steam, the kitchen waste is blown upward and floats toward the downstream direction of the carbonization reaction chamber 4.

[0028] The lower end of the carbonization reaction chamber 4 is a streamlined structure, which reduces the momentum loss of the superheated steam generated in the steam generator 2 after entering the carbonization reaction chamber 4.

[0029] The working principle is:

[0030] Figure 3 This is a schematic diagram of the internal flow of a kitchen waste treatment device using superheated steam according to the present invention. The present invention has three inlets, including a gas inlet 301, a clean water inlet 302, and a kitchen waste inlet 402. The gas inlet 301 serves as a power output source. The gas input from the gas inlet 301 can drive the water in the clean water inlet 302 to flow into the device, and after passing through the nozzle 303, it forms water mist and enters the water mist channel 1. The main heating area of ​​the device is the steam generator 2. When the water mist enters the steam generator 2, it evaporates into water vapor due to the high temperature. In the process of flowing through the spiral guide vanes 201, it is continuously heated by the heating device 202 installed in series with multiple stages of heating. The water vapor fully evaporates and reaches 200 to 1200 degrees Celsius to form superheated steam, which passes through the lower end of the steam generator 2 and enters the carbonization reaction chamber 4.

[0031] After passing through the pulverizer installed in the present invention, the kitchen waste is transformed into a paste and enters the carbonization reaction chamber 4 through the kitchen waste inlet 402. Upon contact with the superheated steam, the paste-like kitchen waste entering the carbonization reaction chamber 4 undergoes dehydration and drying, transforming from a paste into powdered kitchen waste. The superheated steam propels the kitchen waste toward the upper end of the carbonization reaction chamber 4. The residence time of the powdered kitchen waste in the carbonization reaction chamber 4 can be controlled by controlling the gas flow rate at the gas inlet 301 and the water flow rate at the water inlet 302, ensuring that the powdered kitchen waste is fully carbonized by the superheated steam and that harmful organic matter is separated. The treated gas and carbonized matter are discharged from the outlet of the carbonization reaction chamber 4. A separation device and a collection device are installed downstream to separate the steam from the harmful matter and collect the harmful matter and carbonized matter separately. The separated, preheated steam can continue to flow into the device through the gas inlet 301 for recycling, thus better meeting environmental protection requirements.

[0032] The guide vane 401 installed in the carbonization reaction chamber 4 has three main functions. The first is to allow the gas to form a vortex in the carbonization reaction chamber 4, thereby increasing the residence time of the kitchen waste in the carbonization reaction chamber 4; the second is to process a through hole connecting the steam generator 2 and the insulation cover 5 in the guide vane, thereby providing a channel for the electric wires that energize the heating device 202 installed in the carbonization reaction chamber 4; and the third is to assist in supporting the steam generator 2.

[0033] The protection scope of the present invention is not limited to the above-mentioned embodiments, but also includes other embodiments and modifications within the scope of the present invention.
