Obviously, the drawings described below are only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0019] Figure 1 This is a schematic diagram of the structure of a biological enzyme decomposition device and nutrient supply and delivery equipment according to this utility model. Detailed Implementation

[0020] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings. It should be understood that the described embodiments are merely some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0021] like Figure 1As shown in some illustrative embodiments, a nutrient supply and delivery device for a biocatalytic enzyme decomposition apparatus is provided. This device sprays appropriate amounts of nutrients onto the bio-enzyme at regular intervals and in quantitative quantities to supplement the nutrients required for the bio-enzyme's survival, thereby increasing its lifespan and quantity, and creating ideal environmental conditions for the survival and reproduction of the bio-enzyme. The nutrient supply and delivery device in this embodiment specifically includes: a nutrient solution storage tank 1, a metering pump 2, a nutrient solution delivery pipeline 3, a nutrient solution supply pipeline 4, a spray pipeline 5, a filter 6, a control valve assembly, a stirrer 7, a radar level gauge 8, a return pipeline 9, a tank venting pipe 10, a PLC, and a heat exchanger 11.

[0022] Nutrient solution storage tank 1 is used for the preparation of nutrients. Materials are added in batches through the inlet of nutrient solution storage tank 1. Each batch is added only after the previous batch has completely dissolved. Before adding any more materials, a certain amount of softened water must be present in nutrient solution storage tank 1, and the agitator 7 must be turned on. After all materials have been added, the agitator 7 continues to agitate for 1-2 hours to ensure complete dissolution of the nutrients, until no solid particles remain in nutrient solution storage tank 1.

[0023] A stirrer 7 is installed at the top of the nutrient solution storage tank 1 to stir the substances inside the tank, ensuring uniform mixing of the nutrient solution. To meet the demands of actual working conditions, the motor power of the stirrer 7 must be sufficient to ensure effective flow of the liquid inside the tank driven by the impeller. Specifically, the motor power is determined by considering factors such as the characteristics of the material being stirred, the size of the container, the type of stirrer, and the stirring speed. Furthermore, considering the chemical properties of the nutrient solution, the impeller material of the stirrer 7 should be selected from materials with good corrosion resistance to ensure that the stirrer will not be damaged by corrosion during long-term use.

[0024] The stirring rod of the agitator 7 is made of 304 or 316L stainless steel to ensure the corrosion resistance of the parts in contact with the liquid and to ensure that the stirring rod will not corrode even under long-term contact with the nutrient solution. The ratio of the blade width d of the agitator 7 to the diameter D of the nutrient solution storage tank 1 satisfies the condition: 0.35 ≤ d / D ≤ 0.8. This ratio range ensures that the blade size provides sufficient stirring area while ensuring that the liquid forms an effective flow pattern in the tank, making it more suitable for the efficient preparation of nutrients.

[0025] A radar level gauge 8 is installed on top of the nutrient solution storage tank 1 to detect the liquid level inside the tank, preventing the liquid level from being too low and affecting the delivery of the nutrient solution. The radar level gauge 8 is preferably installed using a flange connection, and its placement should consider the space required for future maintenance. This embodiment uses a guided wave radar level gauge, which has a strong ability to suppress steam and foam, and can accurately measure the liquid level even in complex environments with steam or foam. Guided wave radar level gauges are suitable for media with low dielectric constants, low viscosity, and low adhesion, making them ideal for measuring the liquid level of nutrient solutions. The accuracy of the guided wave radar level gauge is selected as 0.5 class. Since only the tank liquid level is detected, the accuracy can be appropriately reduced to ensure functionality while lowering equipment costs.

[0026] The vent pipe 10 is located on the top of the nutrient solution storage tank 1, and the top end of the vent pipe 10 is bent downward so that the top end of the vent pipe 10 faces the ground. This can prevent injury to nearby personnel during the venting operation and reduce the risk of foreign objects entering the tank.

[0027] The nutrient solution storage tank 1 is connected to the inlet of the metering pump 2 via the nutrient solution delivery pipe 3. The outlet of the metering pump 2 is connected to one end of the nutrient solution supply pipe 4, and the other end of the nutrient solution supply pipe 4 is connected to the spray pipe 5. After the metering pump 2 is started, the nutrients stored in the nutrient solution storage tank 1 enter the nutrient solution delivery pipe 3, and then are delivered to the spray pipe 5 via the nutrient solution supply pipe 4. The spray pipe 5 is equipped with a spraying device to evenly spray the nutrient solution into the biocatalytic enzyme decomposition device.

[0028] Metering pump 2 is a vertically designed diaphragm pump. This vertical design effectively handles solid particles in the nutrient solution. Due to its structural characteristics, the diaphragm pump will not clog due to the presence of solid particles, ensuring normal operation. Furthermore, the main structural material of metering pump 2 is 316L stainless steel, which has excellent corrosion resistance, thus extending the pump's service life. Simultaneously, the materials selected for the pump's flow-through components must be compatible with the physical and chemical properties of the pumped liquid to maintain stable operation and extend its service life.

[0029] Filter 6 is installed on the nutrient solution delivery pipeline 3. Its main function is to filter the liquid before it enters the metering pump 2 to remove any solid particles that may be present. Filter 6 is a pipeline Y-type filter, which facilitates liquid flow and effectively intercepts solid particles. Filter 6 is threadedly connected to the nutrient solution delivery pipeline 3, making installation and removal quick and easy. Filter 6 is made of 316L stainless steel, ensuring good corrosion resistance and suitability for environments with prolonged contact with nutrient solution. The filter screen of filter 6 has a filtration accuracy of 50-100μm, which can intercept large solid particles and prevent them from depositing inside the pipeline.

[0030] A first pressure gauge 51 is installed on the spray pipe 5 to monitor the pressure in the spray pipe and ensure that the spraying pressure of the nutrient solution is appropriate. A second pressure gauge 21 is installed on the outlet of the metering pump 2 to detect the outlet pressure of the metering pump 2 and prevent the pump body from becoming blocked and pressure buildup, which could cause damage to the pump body.

[0031] The first pressure gauge 51 and the second pressure gauge 21 are made of 1.6 grade stainless steel, featuring high measurement accuracy and good corrosion resistance, making them suitable for use in various environmental conditions. The measuring range of the first pressure gauge 51 and the second pressure gauge 21 is 1.5-3 times the working pressure, ensuring measurement accuracy while avoiding measurement over-limits due to pressure fluctuations. The operating temperature range of the first pressure gauge 51 and the second pressure gauge 21 is -20℃ to 70℃, adapting to a wide range of temperature variations and ensuring normal operation under different ambient temperatures. The first pressure gauge 51 and the second pressure gauge 21 are connected by flanges, with flange standards conforming to HG / T20592 B series, PN2.5.

[0032] A control valve assembly is installed on the nutrient solution supply pipeline 4. The nutrient solution supply pipeline 4 includes a main pipeline 401 and an auxiliary pipeline 402 arranged in parallel, which are interconnected and can simultaneously deliver nutrient solution, meaning that the nutrient solution can flow in both pipelines at the same time. The control valve assembly includes: a first valve 101, a second valve 102, and a third valve 103. The first valve 101 is installed on the auxiliary pipeline 402, while the second valve 102 and the third valve 103 are both installed on the main pipeline 401.

[0033] By adjusting the first valve 101, the flow rate of the nutrient solution in the auxiliary pipeline 402 can be controlled, thereby achieving fine adjustment of the overall delivery flow rate. The second valve 102 and the third valve 103 allow for rapid on / off operation on the main pipeline 401, facilitating quick shut-off or restoration of the nutrient solution supply during maintenance or emergencies. The parallel design of the main pipeline 401 and the auxiliary pipeline 402 improves the system's flexibility and reliability; when one pipeline requires cleaning or maintenance, the corresponding valve can be closed while the other pipeline continues to operate, ensuring a continuous supply of nutrient solution. Simultaneously, by properly adjusting the valves, the pressure in the two pipelines can be balanced, preventing pipeline damage or nutrient solution leakage due to pressure differences.

[0034] A heat exchanger 11 is installed between the nutrient solution supply pipeline 4 and the metering pump 2. The refrigerant inlet of the heat exchanger 11 is connected to the liquid outlet of the metering pump 2, and the refrigerant outlet of the heat exchanger 11 is connected to the main pipeline 401. The heat exchanger 11 controls the temperature of the nutrient solution, ensuring that it is supplied to the biocatalyst decomposition device at a suitable temperature. The heat exchanger 11 heats the nutrient solution as needed. A suitable temperature can optimize the activity of the biocatalyst, thereby improving the efficiency of the biodecomposition process.

[0035] One end of the return pipe 9 is connected to the nutrient solution supply pipe 4, and the other end of the return pipe 9 is connected to the return inlet of the nutrient solution storage tank 1. The point where the return pipe 9 is connected to the nutrient solution supply pipe 4 is located behind the control valve group.

[0036] The return pipe 9 connects the nutrient solution supply pipe 4 and the nutrient solution storage tank 1. By adjusting the flow rate in the return pipe 9, the amount of nutrient solution entering the bio-catalyst decomposition device can be controlled, allowing for adjustments to the supply based on actual needs and ensuring the bio-catalyst decomposition device receives an appropriate amount of nutrient solution. In the event of an emergency in the bio-catalyst decomposition device, the valve of the return pipe 9 can be closed to quickly stop the spraying of nutrient solution into the device without stopping the pump, thus improving the system's emergency response capability. The return pipe 9 also allows the liquid in the nutrient solution storage tank 1 to circulate, preventing the deposition and crystallization of solid particles in the nutrient solution, maintaining the uniformity and fluidity of the nutrient solution, and contributing to the stable operation of the system.

[0037] The radar level gauge 8, the first pressure gauge 51, and the second pressure gauge 21 are connected to the data input terminal of the PLC, and the control valve group, the agitator 7, and the metering pump 2 are connected to the control output terminal of the PLC.

[0038] Radar level gauge 8 measures the liquid level in nutrient solution storage tank 1 and transmits the data to the PLC. The PLC can control the start and stop of metering pump 2 based on the liquid level information to ensure that the supply of nutrient solution matches the demand. First pressure gauge 51 and second pressure gauge 21 monitor the pressure in the system. The pressure data is sent to the PLC to adjust the operating status of the metering pump or regulate the valve group according to pressure changes, maintaining stable system operation. By setting the start frequency of metering pump 2, nutrient solution can be periodically sprayed into the biocatalytic enzyme decomposition device, providing stable and necessary nutrients to the biocatalysts and supporting their continuous biodecomposition.

[0039] The equipment features a compact structure that makes efficient use of space, making it suitable for the layout characteristics of skid-mounted equipment and facilitating installation and maintenance. The entire system can be installed within a 1500mm × 800mm area, improving space utilization and making it particularly suitable for environments with limited space.
