Description

Technical Field

[0001] This application belongs to the field of biological treatment technology, specifically a black soldier fly larvae decomposer for kitchen waste. Background Technology

[0002] Black soldier flies are saprophytic insects belonging to the family genus *Hemiberlesiae*. Their larvae are characterized by their omnivorous diet, large appetite, and rapid growth, enabling them to efficiently convert organic waste into nutrients in a short period. Native to the Americas, black soldier flies are now widely distributed worldwide. They demonstrate unique advantages and potential in decomposing kitchen waste. Their larvae feed on organic waste such as livestock manure, household garbage, and animal carcasses, converting the waste into proteins, peptides, and oils. In practical applications, black soldier flies are used to treat organic waste such as kitchen waste and livestock manure. Through bioconversion, 60% of easily perishable waste is converted into high-quality insect protein, and 40% becomes insect excrement organic fertilizer.

[0003] For example, CN217284512U discloses a modular, odorless, high-density black soldier fly culturing device using kitchen waste. This device includes a cylindrical culturing tank for holding the kitchen waste pile and a stirrer. The top of the culturing tank has a circular inlet and an outlet, while the bottom has a discharge outlet. The stirrer is spiral-shaped and extends into the culturing tank from the top. This invention solves the problems of low productivity per unit area, excessively large site requirements, and odor pollution associated with black soldier fly culturing using kitchen waste, and is worthy of widespread application.

[0004] However, during actual use, it was discovered that biogas is easily produced during the biodegradation process. In a confined environment, this gas can cause increased pressure, posing a certain safety hazard to the entire device. Therefore, the biogas needs to be treated. Biogas mainly contains methane and sulfur-containing compounds. Since the methane can be recovered and reused, the sulfur-containing compounds should be treated to recover and reuse the methane. Utility Model Content

[0005] The purpose of this application is to provide a black soldier fly larvae decomposer for kitchen waste in order to solve the problem of treating biogas sulfides generated during degradation as mentioned above.

[0006] The technical solution adopted in this application is as follows: a black soldier fly larvae food waste decomposer, wherein an air guide pipe is fixedly inserted into the side surface of the decomposer body, an air pump is fixedly inserted into the side surface of the air guide pipe relative to one end of the decomposer body, a pumping pipe is fixedly inserted into the side surface of the pumping pipe relative to one end of the air guide pipe, a wet desulfurization box is fixedly inserted into the side surface of the wet desulfurization box relative to one end of the pumping pipe, an air intake pipe is inserted into the side surface of the wet desulfurization box relative to one end of the air intake pipe, a gas collecting tower is inserted into the side surface of the wet desulfurization box, a liquid intake pipe is inserted into the side surface of the wet desulfurization box, a liquid outlet pipe is inserted into the side surface of the wet desulfurization box, and a shut-off valve is provided on the side surface of the liquid outlet pipe.

Operators use the extraction assembly to extract the biogas produced during decomposition, which then passes through the connected desulfurization assembly to remove sulfur compounds. Finally, the gas collection assembly collects the desulfurized gas for later use. Through these components, operators can treat and recycle the gas generated during decomposer operation, thus solving safety issues and increasing economic benefits.

[0008] The decomposer body serves as the main site for the decomposition process, while the gas guide pipe inserted into it acts as a gas guide pipe. An air pump is used as the power component for gas extraction. The gas inside the decomposer body is extracted through the gas guide pipe and then sent out through the pump pipe.

[0009] The gas is then pumped into a wet desulfurization tank via a pump pipe. The desulfurization compounds placed inside the tank react with the sulfur-containing compounds to achieve desulfurization. Because the pump pipe is located at the bottom of the wet desulfurization tank, the reaction process is more complete. A liquid inlet pipe is used as the introduction component for the desulfurization compounds, and an outlet pipe is used to discharge the treated sulfur-containing compounds. A shut-off valve on the outlet pipe serves as the control for the pipeline.

[0012] By adopting the above technical solution, the pump base is used as the base component of the pump for fixing the pump. The pump housing is used as the external frame component of the pump.

[0013] In a preferred embodiment, a feed pipe is provided on the side surface of the decomposer body, and a connecting vertical plate is fixedly connected to the side surface of the feed pipe.

[0019] In a preferred embodiment, a cleaning tube cover plate is rotatably connected to the side surface of the cleaning tube.

[0020] By adopting the above technical solution, the cleaning pipe is sealed with a cleaning pipe cover plate.

[0021] In a preferred embodiment, a plurality of decomposer bases are fixedly connected to the bottom surface of the decomposer body.

[0022] By adopting the above technical solution, the resolver base is used as a component to support the resolver body.

[0023] In a preferred embodiment, a plurality of desulfurization tank bases are fixedly connected to the bottom surface of the wet desulfurization tank.

[0024] By adopting the above technical solution, the desulfurization box base is used as a component to support the wet desulfurization box.

[0025] In summary, due to the adoption of the above technical solution, the beneficial effects of this application are:

[0026] In this application, the decomposer body serves as the main site for the decomposition process, and the gas guide pipe inserted therein serves as the gas guide pipe. The gas pump is used as the power component for gas extraction. After the gas inside the decomposer body is extracted through the gas guide pipe, it is transmitted to the outside through the pump pipe.

[0027] The gas is then pumped into a wet desulfurization tank via a pump pipe. The desulfurization compounds placed inside the tank react with the sulfur-containing compounds to achieve desulfurization. Because the pump pipe is located at the bottom of the wet desulfurization tank, the reaction process is more complete. A liquid inlet pipe is used as the introduction component for the desulfurization compounds, and an outlet pipe is used to discharge the treated sulfur-containing compounds. A shut-off valve on the outlet pipe serves as the control for the pipeline.

[0028] The treated gas is conducted to the gas collection tower through the gas inlet pipe and collected for recycling. Attached Figure Description

The desulfurization compound placed in the wet desulfurization tank 5 reacts with the sulfur-containing compound to achieve desulfurization. Because the pump pipe 4 is located at the bottom of the wet desulfurization tank 5, the reaction process is more complete. The liquid inlet pipe 8 serves as the introduction component for the desulfurization compound, and the treated sulfur-containing compound is discharged through the liquid outlet pipe 9.

Through these components, the operator can process and reuse the gas generated during the decomposer's operation, thus solving the safety issues of the device and increasing economic benefits.

[0049] The decomposer body 1 serves as the main site for the decomposition process, while the gas guide pipe 2 inserted therein serves as the gas guide pipe. The gas pump 3 is used as the power component for gas extraction. The gas inside the decomposer body 1 is extracted through the gas guide pipe 2 and then transmitted to the outside through the pump pipe 4.
