Abstract
Description
Technical Field
[0001] This utility model belongs to the field of wet waste catalytic treatment technology, and in particular relates to a high-temperature enzyme catalytic device for wet waste. Background Technology
[0002] This method is used to convert wet waste into a carbon source for denitrification in wastewater. Wet waste includes food scraps from canteens and restaurants, discarded fruits and vegetables and food waste from households, fruit peels, etc. It requires sieving to remove non-degradable inorganic impurities such as plastics and waste paper. After pasteurization at 65℃ for 1 hour, it is pulverized and pulped to a particle size ≤50mm, with a weight ratio of starch, cellulose, and fats of 4:4:2. The wet waste undergoes pretreatment by sterilization and pulverization, followed by uniform stirring and pulping. After stirring, it is stored in a refrigerator and then placed in a reaction apparatus. A single enzyme (such as α-amylase, saccharifying enzyme, or cellulase, added at 1%–5% of the COD value of the wet waste hydrolysate) or a compound enzyme is added. High-temperature enzymatic conversion is carried out at 55–100℃ for about 300 minutes, converting the wet waste into a small-molecule carbon source. After the reaction, it is autoclaved in a boiling water bath for 20 minutes to inactivate the enzymes. However, it still has the following drawbacks in practical use:
[0003] During operation, heating is usually done by directly heating the wet waste, and the wet waste is decomposed under the action of high-temperature enzymes. During the decomposition of wet waste, the wet waste is heated and kept at 55-100 degrees Celsius. After the enzyme catalysis is completed, the wet waste needs to be transferred to a wastewater bath heating device for wastewater bath heating. Two devices are needed to complete the work, which takes up more space and has a longer working process.
[0004] Secondly, the catalytic process in wet waste typically uses ordinary heating containers, which are usually heated at low temperatures and cannot create a high-pressure environment inside. Therefore, when heating to inactivate enzymes in wet waste, a high-pressure environment cannot be guaranteed inside the container. Utility Model Content
[0005] The purpose of this invention is to provide a high-temperature enzyme catalysis device for wet waste. By setting up a heating component, a hopper and a drive motor, it solves the problems that different equipment is needed for catalysis and water bath inactivation of wet waste during decomposition, resulting in high equipment and space costs, and that single equipment is not suitable for both enzyme catalysis and inactivation.
[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0007] This utility model relates to a high-temperature enzyme catalysis device for wet waste, comprising a heating component, a hopper, and a drive motor. The heating component includes a hot water tank, a sealing sleeve, and a thermal switch. The hopper is vertically fixed inside the hot water tank. A feed pipe, a solution pipe, and an aeration pipe are fixedly connected to the top of the hopper, arranged in a ring array at the top of the hopper. A thermal switch is fixed in the center of the periphery of the hot water tank. A drive motor is fixed in the center of the top of the hopper. A sealing sleeve is fixed in the inner bottom of the hot water tank. An annular heater is fixed in the cavity inside the sealing sleeve. During operation, the heating component heats the hopper, and the thermal switch maintains the water temperature in the hot water tank between 55-80 degrees Celsius. The wet waste slurry is contained within the hopper, and the drive motor drives a rotating shaft to stir the slurry evenly.
[0008] Furthermore, the heating assembly also includes a water inlet pipe and an exhaust pipe. The top of the hot water tank is fixedly connected to the water inlet pipe and the exhaust pipe. The water inlet pipe and the exhaust pipe are symmetrically arranged at the top of the hot water tank. The heating assembly replenishes water into the hot water tank through the water inlet pipe and discharges the steam generated by the wastewater in the hot water tank to the exhaust device through the exhaust pipe.
[0009] Furthermore, the heating assembly also includes an insulation shell, the surface of the hot water tank is fixed with the insulation shell, the water inlet pipe and the exhaust pipe pass through the top of the insulation shell and extend out, the thermal switch extends out of the periphery of the insulation shell, and a support frame is fixed to the lower periphery of the insulation shell. When the heating assembly is working, the insulation shell insulates the hot water tank, and the support frame supports the heating assembly and the hopper on the ground.
[0010] Furthermore, a discharge pipe is fixedly connected to the bottom of the silo, and an electric control valve is fixed around the feed pipe, solution pipe, air filling pipe and discharge pipe. When the silo is working, the wet waste slurry after catalysis and high-temperature inactivation of the catalytic enzyme in the silo is discharged through the discharge pipe.
[0011] Furthermore, the output tube of the drive motor is fixed with a rotating shaft that passes through the top of the hopper. The bottom end of the rotating shaft is rotatably connected to the inner bottom of the hopper, and the power generated by the drive motor drives the rotating shaft to rotate.
[0012] Furthermore, stirring blades are fixed in a ring array around the circumference of the rotating shaft. The stirring blades are arranged inside the hopper, and when the stirring blades rotate, they stir the material in the hopper evenly.
[0013] This utility model has the following beneficial effects:
[0014] This invention solves the problem of high equipment and space costs associated with the separate operation of catalytic and water bath inactivation of wet waste during decomposition by incorporating a heating component, a silo, and a drive motor. When the silo is in operation, heating water is first supplied to the hot water silo through an inlet pipe. After the wet waste and enzymes are added to the silo, the drive motor is started, simultaneously activating the thermal switch and the annular heater. The annular heater heats the water in the hot water silo until it reaches over 80 degrees Celsius. The temperature is then transmitted to the thermal switch, shutting off the annular heater in the hot water silo. After the hot water temperature drops below 55 degrees Celsius, the annular heater is turned on. The heat generated by the annular heater is transferred to the hot water in the hot water tank through the sealed sleeve, heating the hot water. After the enzyme catalytic reaction in the silo lasts for five hours, the thermal switch is turned off, and the annular heater is started directly until the water in the hot water tank is heated to boiling. After maintaining the boiling state for 20 minutes, the enzyme in the silo is inactivated. This allows the wet waste in the silo to complete the high-temperature conversion and inactivation of the enzymes. This eliminates the need for separate equipment for catalytic and water bath inactivation of wet waste during decomposition, resulting in lower equipment and space costs.
[0015] This invention solves the problem of insufficient applicability of enzyme catalysis and inactivation conditions in wet waste decomposition using a single device by setting up a hopper. After the catalytic process is completed, the electric control valve on the air inlet pipe is opened to pressurize the hopper, so that it reaches the high-pressure environment for enzyme decomposition. Then, the electric control valve on the air inlet pipe is closed, and the drive motor continues to work. After the enzyme inactivation operation is completed, the electric control valve on the discharge pipe is opened to discharge the material in the hopper, thus ensuring good applicability of enzyme inactivation conditions after enzyme inactivation.

Detailed Implementation
[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model. Specific Implementation Example 1
[0025] Please see Figure 1-3This utility model is a high-temperature enzyme catalysis device for wet waste, including a heating component 1, a hopper 2, and a drive motor 3. The heating component 1 includes a hot water tank 101, a sealing sleeve 102, and a thermal switch 106. The hopper 2 is vertically fixed inside the hot water tank 101. When the hot water tank 101 is working, it contains hot water to heat the wet waste in the hopper 2. The wet waste to be enzymatically decomposed is contained in the hopper 2. The top of the hopper 2 is fixedly connected to an inlet pipe 201, a solution pipe 202, and an air inlet pipe 203. 1. Solution pipe 202 and aeration pipe 203 are arranged in a ring array at the top of silo 2. The top of feed pipe 201 is connected to the pipeline for inputting wet waste material, the top of solution pipe 202 is connected to the pipeline for conveying enzyme solution, and the top of aeration pipe 203 is connected to the pipeline for inputting high-pressure air. The pre-prepared slurry-like wet waste is transported to silo 2 through feed pipe 201, the enzyme solution is transported to silo 2 through solution pipe 202, and high-pressure air is transported to silo 2 through aeration pipe 203 to pressurize silo 2. A thermal switch 106 is fixed at the center of the periphery of the hot water tank 101. When wet waste decomposition is required, the thermal switch 106 is activated. The operating temperature of the thermal switch 106 is between 55 and 80 degrees Celsius (i.e., the ring heater 1021 is activated when the temperature of the silo 2 is below 55 degrees Celsius, and the ring heater 1021 is deactivated when the temperature is above 80 degrees Celsius), ensuring that the catalytic temperature of the wet waste in the silo 2 is maintained between 55 and 80 degrees Celsius. A drive motor 3 is fixed at the center of the top of the silo 2, which drives the stirring of the silo 2. The structure of the wet waste rotates, and a sealing sleeve 102 is fixed to the inner bottom of the hot water tank 101. An annular heater 1021 is fixed in the cavity inside the sealing sleeve 102. The annular heater 1021 is fixed to the inner bottom of the hot water tank 101. The annular heater 1021 generates heat to heat the water in the hot water tank 101. The annular heater 1021 is sealed inside the hot water tank 101 by the sealing sleeve 102. When the annular heater 1021 is working, the heat generated is transferred to the water in the hot water tank 101 through the sealing sleeve 102.
[0026] Specifically, the heating component 1 also includes a water inlet pipe 104 and an exhaust pipe 105. The top of the hot water tank 101 is fixedly connected to the water inlet pipe 104 and the exhaust pipe 105. The water inlet pipe 104 and the exhaust pipe 105 are symmetrically arranged at the top of the hot water tank 101. When the heating component 1 is working, the top of the water inlet pipe 104 is connected to a device for replenishing water in the hot water tank 101, and the top of the exhaust pipe 105 is connected to a device for heating and generating steam from the water in the hot water tank 101. This allows water to be replenished in the hot water tank 101 through the water inlet pipe 104. After the water in the hot water tank 101 boils, the steam is discharged to the steam output device through the exhaust pipe 105.
[0027] Furthermore, the heating assembly 1 also includes an insulation shell 103. The insulation shell 103 is fixed to the surface of the hot water tank 101. The water inlet pipe 104 and the exhaust pipe 105 pass through the top of the insulation shell 103 and extend out. The thermal switch 106 extends out of the periphery of the insulation shell 103. A support frame 4 is fixed to the lower periphery of the insulation shell 103. When the heating assembly 1 is working, the hot water in the hot water tank 101 is kept warm through the insulation shell 103.
[0028] The operation process of this embodiment is as follows: During operation, when the hopper 2 is working, heating water is first transported to the hot water tank 101 through the water inlet pipe 104 to contain the water. Then, after the wet waste and enzymes are transported into the hopper 2, the drive motor 3 is started, and simultaneously the thermal switch 106 and the annular heater 1021 are activated. The annular heater 1021 heats the water in the hot water tank 101 until the water in the hot water tank 101 reaches a temperature above 80 degrees Celsius. The temperature is then transmitted to the thermal switch 106, shutting off the operation of the annular heater 1021. When the water in the hot water tank 101... After the hot water temperature drops below 55 degrees Celsius, the annular heater 1021 is turned on. After the annular heater 1021 is turned on, the heat generated is transferred to the hot water in the hot water chamber 101 through the sealing sleeve 102 to heat the hot water. After the enzyme catalytic reaction in the hopper 2 lasts for five hours, the thermal switch 106 is turned off and the annular heater 1021 is turned on directly until the water in the hot water chamber 101 is heated to boiling and kept boiling for 20 minutes. Then the enzyme in the hopper 2 is inactivated, so that the wet waste in the hopper 2 can complete the high-temperature conversion and inactivation of the enzyme. Specific Implementation Example 2
[0029] Please see Figure 1-5 Based on the first specific embodiment, the bottom end of the silo 2 is fixedly connected to the discharge pipe 204, and the bottom end of the discharge pipe 204 is connected to the receiving equipment. The feed pipe 201, solution pipe 202, aeration pipe 203 and discharge pipe 204 are all fixed with electric control valves 205. When the silo 2 is working, the catalyzed material in it is discharged through the discharge pipe 204. The feed pipe 201, solution pipe 202, aeration pipe 203 and discharge pipe 204 are all controlled by electric control valves 205.
[0030] Specifically, the output pipe of the drive motor 3 is fixed with a rotating shaft 301 that passes through the top of the hopper 2. The bottom end of the rotating shaft 301 is rotatably connected to the inner bottom of the hopper 2. The power generated by the drive motor 3 drives the rotating shaft 301 to rotate.
[0031] Furthermore, stirring blades 302 are fixed in a ring array around the circumference of the rotating shaft 301. The stirring blades 302 are set inside the hopper 2. When the rotating shaft 301 rotates, it drives the stirring blades 302 to rotate, thereby stirring the material in the hopper 2.
[0032] The operation process of this embodiment is as follows: During operation, the wet waste slurry is first transported to the silo 2 through the feed pipe 201 by opening the electric control valve 205 on the feed pipe 201. After the transport is completed, the electric control valve 205 on the feed pipe 201 is closed, and then the electric control valve 205 on the solution pipe 202 is started to transport an appropriate amount of enzyme solution to the silo 2. After the transport is completed, the electric control valve 205 on the solution pipe 202 is closed, and then the drive motor 3 is started. The drive motor 3 drives the rotating shaft 301 to rotate the stirring blade 302, which fully mixes the enzyme solution and wet waste slurry in the silo 2 and catalyzes while stirring. After the catalytic process is completed, the electric control valve 205 on the aeration pipe 203 is opened to pressurize the silo 2 so that it reaches the high pressure environment for enzyme decomposition. Then the electric control valve 205 on the aeration pipe 203 is closed, and the drive motor 3 is kept running. After the enzyme inactivation operation is completed, the electric control valve 205 on the discharge pipe 204 is opened to discharge the material in the silo 2.
