Description

Technical Field

[0001] The invention relates to a low-temperature infrared radiation coupled biological reaction method and a device thereof, belonging to the field of biomass waste resource processing. Background Art

[0002] Aerobic biological treatment refers to a treatment method that uses aerobic microorganisms (including facultative microorganisms) to metabolize organic matter in the presence of oxygen to stabilize and render it harmless. Microorganisms use existing organic pollutants as substrates for aerobic metabolism, and after a series of biochemical reactions, they release energy step by step, and eventually stabilize as low-energy inorganic matter, achieving the requirement of harmlessness, so that they can be returned to the natural environment or further treated.

[0003] At present, the main heating methods used are thermal aeration and heat conduction. The heat conduction heating rate has a slow response, and the temperature is difficult to be directly transmitted to the center point, which has high energy consumption and poor thermal insulation performance, which greatly increases the heat dissipation. Thermal aeration uses hot air to pass through the biomass pile for direct contact heating. The moment the hot air contacts the biomass material, the surface water vapor will evaporate, directly reducing the temperature of the biomass material, thereby taking most of the heat out of the system, so that the entire reaction temperature cannot reach the expected temperature, affecting the experimental effect. Summary of the invention

[0004] In view of the shortcomings and deficiencies of the prior art, the purpose of the present invention is to provide a low-temperature infrared radiation coupled biological reaction method and a device thereof, which couples the traditional biomass passage for microbial aerobic reaction with infrared radiation, changes the heat transfer from contact to non-contact, and changes the thermal aeration that maintains the material temperature by heat convection heat transfer to thermal radiation, which greatly improves the problem that the hot air quickly passes through the biomass surface, instantly taking away a large amount of water vapor from the biomass surface, and the water evaporation absorbs heat, so that the actual material temperature cannot reach the ideal temperature, optimizes the entire microbial reaction process, greatly improves the microbial reaction activity, further shortens the reaction cycle, and improves the reaction efficiency.

[0005] In order to achieve the above object, the present invention provides a low-temperature infrared radiation coupled biological reaction method, the steps are as follows:

[0006] The biomass material is naturally piled up or placed in a stirring device, and infrared irradiated by an infrared irradiation device. Under the action of heat generation by microbial fermentation, the temperature of the material is further controlled by controlling the power of the infrared irradiation device and the rate of air introduction, so as to provide a stable and suitable environmental temperature for aerobic fermentation and heat generation of microorganisms in the biomass. By turning the pile or mechanical stirring, the temperature of the entire material is promoted to be uniform to ensure the efficient progress of the entire microbial reaction. After the reaction is completed, the material is emptied in time, discharged, and new biomass material is filled in, and the above operation is repeated to realize continuous operation of the process.

[0007] Furthermore, the air introduced is room temperature air, which can provide oxygen for the microbial reaction and provide rapid heat dissipation when the material temperature is too high (higher than the maximum temperature suitable for microbial survival), ensuring that the material temperature is maintained within a suitable ambient temperature range, providing a stable and suitable ambient temperature for the aerobic fermentation heat production of microorganisms in the biomass.

[0008] Furthermore, the biomass materials include organic matter such as straw, feces, domestic garbage, and kitchen waste, but are not limited to the above.

[0009] Furthermore, the temperature of the material is further controlled by controlling the power of the infrared irradiation device and the rate of air introduction, so as to provide a stable and suitable environmental temperature for the aerobic fermentation heat production of microorganisms in the biomass, which can be specifically:

[0010] When the material temperature is lower than the minimum temperature suitable for the survival of microorganisms, increase the power of the infrared irradiation device, or reduce the rate of air introduction, or increase the power of the infrared irradiation device and reduce the rate of air introduction at the same time, so that the material temperature is maintained within the appropriate ambient temperature range;

[0011] When the material temperature is higher than the maximum temperature suitable for the survival of microorganisms, the air supply rate is increased, or the infrared irradiation power is reduced, or the air supply rate is increased and the power of the infrared irradiation device is reduced at the same time, so that the material temperature is maintained within the appropriate ambient temperature range.

[0012] Furthermore, the reaction time is 24-72 hours.

[0014] The biomass material enters the reactor through the feed port at the upper end of the reactor, is heated by the infrared irradiation device, and is evenly mixed by the stirring device, and a biological reaction occurs. After the reaction is completed, the material is discharged from the discharge port at the lower end of the reactor.

[0018] The stirring device is a prior art in the art, preferably a double-shaft stirring device, which is used to mix the biomass materials to make them uniformly mixed. For example, a double-screw compost turning shaft includes a forward screw compost turning shaft and a reverse screw compost turning shaft, wherein the forward screw compost turning shaft and the reverse screw compost turning shaft are controlled by a driving motor to realize synchronous operation, and the forward screw compost turning shaft and the reverse screw compost turning shaft rotate in opposite directions.

[0019] Furthermore, the lower box of the reactor has a compost turning plate structure, which is a prior art in the art. A compost turning plate is provided at the end of one end of the twin-screw compost turning shaft to facilitate the reciprocating movement of materials in the two grooves, so that the reaction is more complete and the materials are mixed more evenly.

[0020] Furthermore, the pile turning plate is an arc-shaped structure.

[0021] Furthermore, the cross section of the upper cover of the reactor is a triangular structure, and the condensed water formed on the inner wall surface of the upper cover can flow down freely. The condensed water collecting tank above the infrared irradiation device is used to collect the condensed water generated during the process.

[0022] Furthermore, the air inlet at the lower end of the reactor is connected to a low-temperature aeration tank for introducing air into the reactor to provide oxygen for microbial reaction. Ventilation and oxygenation avoid anaerobic reaction, so as to maximize the oxidation function of the material.

[0023] Furthermore, a thermocouple for online temperature collection in the reactor is provided in the reactor, and the thermocouple is connected to a temperature controller, an infrared irradiation device, and a low-temperature aeration tank. The temperature of the material is controlled by controlling the power of the infrared irradiation device and the rate of air introduction, thereby providing a stable and suitable ambient temperature for aerobic fermentation heat production by microorganisms in the biomass.

[0024] Furthermore, the temperature controller is a temperature controller.

[0025] Furthermore, the discharge port at the lower end of the reactor is connected to a solid waste treatment unit, and the material discharged from the reactor enters the solid waste treatment unit for solid waste treatment.

[0027] Furthermore, the gas outlet is a water vapor duct.

[0028] Furthermore, the liquid outlet at the lower end of the reactor is connected to a waste liquid treatment unit, and the liquid discharged from the reactor enters the waste liquid treatment unit for waste liquid treatment.

[0029] The low-temperature aeration tank, solid waste treatment unit, waste gas treatment unit, and waste liquid treatment unit are all existing technologies in the field, and technicians in the field can select or combine them according to actual conditions.

[0030] The above-mentioned method for treating biomass waste by using a low-temperature infrared radiation coupled bioreactor comprises the following steps:

[0031] The biomass material enters the reactor through the feed port at the upper end of the reactor, the material is irradiated and heated by the infrared irradiation device above the material, the material is evenly mixed by the stirring device, and air is introduced into the reactor through the low-temperature aeration tank to provide oxygen for the microbial reaction. The material after the reaction is discharged from the discharge port at the lower end of the reactor, and new biomass material is filled in. The above operation is repeated to realize continuous operation of the process.

[0032] Under the action of heat production by microbial fermentation, the temperature of the material is further controlled by controlling the power of the infrared irradiation device and the rate of air introduction, providing a stable and suitable ambient temperature for the aerobic fermentation heat production of microorganisms in the biomass. Mechanical stirring is performed regularly every day to promote the uniformity of the temperature of the entire material to ensure the efficient progress of the entire microbial reaction.

[0033] The gas generated after the reaction is drawn out of the reactor through the induced draft fan and enters the exhaust gas treatment unit through the steam channel for exhaust gas treatment. The condensed water generated by the reaction is collected through the condensed water collection tank, and the liquid generated after the reaction is discharged from the liquid outlet at the lower end of the reactor for residual liquid treatment.
