Description

Technical Field

[0001] This utility model relates to the technical field of solid waste pollution treatment equipment, and in particular to a novel horizontal rotary high-efficiency bio-enzyme catalytic fermentation treatment system. Background Technology

[0002] Currently, commonly used treatment technologies in China include anaerobic fermentation for biogas production, aerobic composting combined with organic fertilizer production, and in-situ fermentation beds. However, these technologies generally suffer from the following problems during their application:

[0003] (1) Anaerobic fermentation produces biogas with low yield and low energy efficiency. Anaerobic acidification hydrolysis produces biogas residue with virtually no fertilizer effect. As a raw material for organic fertilizer, its utilization rate is too low and it is significantly affected by seasonality.

[0004] (2) In-situ fermentation bed has high bedding costs, is prone to microbial imbalance, requires frequent replacement, is difficult to control odor, is prone to the growth of viruses and bacteria, and is difficult to manage and has poor technical adaptability. It is only suitable for small-scale rural family farming.

[0005] (3) Aerobic composting is the most common (80%) method for producing organic fertilizer:

[0006] Large footprint and long processing cycle (biological fermentation generally takes 20-40 days), mechanical natural fermentation (40-70 days).

[0007] Odor emissions are difficult to control. The composting process generates a large amount of foul-smelling gases, which can easily breed mosquitoes and flies and produce viruses and bacteria, causing serious impacts on the surrounding environment and residents.

[0008] Nutrient loss and unstable product quality: During the composting process, severe water evaporation and nutrient volatilization lead to the loss of nutrients such as nitrogen. At the same time, if not properly managed, leachate may pollute groundwater or surface water.

[0009] In summary, although there is a certain application foundation in the treatment of livestock and poultry manure in China, it generally suffers from problems such as low energy efficiency, high environmental pollution risk, high operating costs, and high management difficulty, making it difficult to meet the increasingly stringent requirements of green farming, resource recycling, and environmental protection supervision. Summary of the Invention

[0010] The purpose of this invention is to provide a novel horizontal rotary high-efficiency bio-enzyme catalytic fermentation system to solve the above-mentioned problems.

[0011] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0012] A novel horizontal spiral-propelled high-efficiency bio-enzyme catalytic fermentation treatment system is disclosed. The system includes a bio-enzyme catalytic fermentation reactor, which comprises a horizontal reactor tank. A twin-shaft spiral material propulsion device and a gas distribution branch pipe are installed inside the horizontal reactor tank. The inlet end of the horizontal reactor tank is independently connected to a mixing feed trough and a gas supply pipe. The gas distribution branch pipe is connected to the outlet of the gas supply pipe. The inlet of the gas supply pipe is connected to a steam thermal generator. The outlet end of the horizontal reactor tank is independently equipped with a waste gas collection pipe and a discharge port. The outlet end of the waste gas collection pipe is connected to a negative ion biological waste gas treatment device.

[0013] As a preferred technical solution, a directional roller sliding support is provided in the horizontal reactor tank near the outlet.

[0014] As a preferred technical solution, a fully sealed belt conveyor is provided above the mixing feed trough, and a material mixing device is provided at the input end of the fully sealed belt conveyor, wherein a double spiral mixing agitator is provided inside the material mixing device.

[0015] As a further preferred technical solution, a crane is correspondingly installed above the double helix mixer, and the double helix mixer is also connected to a material conveying pump, with a material feeding device installed at the other end of the material conveying pump.

[0016] As a preferred technical solution, the discharge port is connected to a fully sealed belt conveyor.

[0017] As a preferred technical solution, the inlet end of the negative ion biological waste gas treatment device is also connected to a centrifugal exhaust fan.

[0018] This invention employs a bio-enzyme catalytic fermentation reactor, utilizing biomass technology based on the principle of enzyme kinetics to simulate the biomimetic digestive system of animals in nature. The raw materials are mixed in a high-temperature and aerobic environment in a tank-type device, where they undergo rapid catalytic fermentation and high-temperature enzymatic hydrolysis. A dual-axis spiral material propulsion device is used to propel the reactants, with the spiral side arcs preferably designed as scrapers that fit against the inner wall of the reactor, completing multiple processes such as stirring and mixing the materials, uniform reaction, and uniform propulsion.

[0019] Compared with the prior art, the advantages of this utility model are as follows: the treatment system of this utility model is used for the harmless treatment of manure generated during the livestock and poultry breeding process, with a treatment time of only 6-8 hours, which is fast and efficient; the manure is 100% converted into high-quality organic fertilizer with no loss of fertilizer effect; the whole set of equipment occupies a small area, only 1 / 10 of the traditional treatment equipment; the whole process adopts an integrated equipment system, and no odor or other polluting gases are generated during the treatment process, which is conducive to environmental protection.

[0022] The present invention will be further described below with reference to the embodiments.

[0023] The bio-enzyme catalytic fermentation reactor and the negative ion biological waste gas treatment device used in the following embodiments are both existing technologies. For example, the HG25-SR-W-20-A bio-enzyme catalytic fermentation reactor and the HQ23-SXG-330-8 / 20-A negative ion biological waste gas treatment device, both commercially available from Chengdu Lvlan Environmental Protection Technology Co., Ltd., can be used.

[0024] As is known to those skilled in the art: Bio-enzyme catalytic fermentation reactors are based on enzyme kinetics principles, mimicking the biomimetic digestive system of animals in nature. Raw materials are mixed in a tank-type device under a high-temperature, aerobic environment, enabling rapid catalytic fermentation and high-temperature enzymatic hydrolysis. Negative ion biological waste gas treatment devices utilize negative ions to react with waste gas molecules SO2 / NO... X When pollutants react with each other, inelastic collisions occur, converting energy into the internal energy of ground-state molecules. This leads to a series of processes such as excitation, dissociation, and ionization. Gas molecules can be adsorbed, activating the gas and causing chemical oxidation-reduction reactions, which decompose it into carbon dioxide and water. Example

[0025] See Figure 1A novel horizontal spiral-propelled high-efficiency bio-enzyme catalytic fermentation treatment system is disclosed. The system includes a bio-enzyme catalytic fermentation reactor 1, which comprises a horizontal reactor tank 12. A dual-axis spiral material propulsion device 2 and a gas distribution branch pipe 15 are installed within the horizontal reactor tank 12. The inlet end of the horizontal reactor tank 12 is independently connected to a mixing feed trough 4 and a gas supply pipe 16.

The outlet end of the horizontal reactor tank 12 is independently equipped with a waste gas collection pipe 17 and a discharge port 11. The outlet end of the waste gas collection pipe 17 is connected to a negative ion biological waste gas treatment device 10. The inlet end of the negative ion biological waste gas treatment device 10 is also connected to a centrifugal exhaust fan 18.

[0026] In this embodiment, a directional roller sliding support 3 is provided inside the horizontal reactor tank 12 near the outlet.

[0027] A fully sealed belt conveyor 7 is installed above the mixing feed trough 4. A material mixing device 6 is installed at the input end of the fully sealed belt conveyor 7.

[0028] The discharge port 11 is also connected to a fully sealed belt conveyor 7;

[0029] During operation, manure is added to the double-spiral mixer 14 via crane 20. Simultaneously, compound biological protease, mixed biomass, etc., are added to the double-spiral mixer 14 via material feeding device 8 and material conveying pump 19 for mixing. After uniform mixing, the mixture enters the material mixing device 6, and then is conveyed to the mixing feed trough 4 via fully sealed belt conveyor 7, and then enters the bio-enzyme catalytic fermentation reactor 1. At the same time, the steam heat generator is started, and hot steam is supplied through the gas supply pipe 16 into the bio-enzyme catalytic fermentation reactor 1. The hot steam and the mixed materials undergo fermentation treatment in the bio-enzyme catalytic fermentation reactor 1. Generally, the mixture is pushed to the outlet of the bio-enzyme catalytic fermentation reactor 1 by the action of the double-screw material propulsion device 2. The organic fertilizer produced by fermentation is conveyed to the finished product collection box 9 via fully sealed belt conveyor 7. The generated waste gas enters the negative ion biological waste gas treatment device 10 for treatment through the waste gas collection pipe 17, and is discharged through the centrifugal exhaust fan 18 after treatment.
