[0065] Embodiment 1

[0066] A chemical energy storage prefabricated cabin wastewater collection device, Figure 1 A cross-sectional view of the overall structure of an embodiment of the present invention is shown; Figure 2 FIG. 2 shows a side view of the overall structure of an embodiment of the present invention; Figure 1 and Figure 2 As shown, including:

[0067] Shell 1, suction assembly 2, collection assembly 3, heat exchange assembly 4, filter assembly 5 and control assembly;

[0068] The shell 1 is arranged outside the chemical energy storage prefabricated cabin; the first installation cavity and the second installation cavity are arranged in sequence in the vertical direction inside the shell 1; the shell 1 is the main structure of the entire wastewater collection device, and is arranged outside the chemical energy storage prefabricated cabin to isolate the treatment process from other equipment in the prefabricated cabin to ensure safe operation. The interior of the shell is divided into the first installation cavity and the second installation cavity. This vertical layered design not only optimizes space utilization, but also facilitates the installation, maintenance and overhaul of each component.

[0069] A suction component 2 is provided in the first installation cavity, and the input end of the suction component 2 is connected to the chemical energy storage prefabricated cabin, and is used to extract the wastewater in the chemical energy storage prefabricated cabin; the suction component 2 is a key component for wastewater collection, and its input end is connected to the inside of the chemical energy storage prefabricated cabin, and the wastewater generated in the prefabricated cabin is effectively extracted by negative pressure or pump suction. The working parameters of the suction component (such as suction rate, pressure, etc.) can be precisely adjusted by the control component to meet the needs of different wastewater collection volumes. Considering that the chemical properties of wastewater may be corrosive, the material of the suction component must have good corrosion resistance to ensure long-term stable operation.

[0070] The second installation cavity is provided with a collecting assembly 3, and the output end of the suction assembly 2 is connected to the collecting assembly 3; the collecting assembly 3 is located in the second installation cavity and is used to receive and temporarily store the wastewater extracted from the suction assembly 2. Its design needs to consider the capacity, fluidity and possible sediment treatment of the wastewater. The collecting assembly 3 may be made of corrosion-resistant materials and equipped with monitoring equipment such as liquid level sensors, so as to timely grasp the wastewater storage situation and take corresponding treatment measures.

[0071] A heat exchange component 4 is disposed below the outside of the collection component 3, and the heat exchange component 4 is used to heat the liquid in the collection component 3; the heat exchange component 4 is disposed below the outside of the collection component 3, and promotes the evaporation of water in the wastewater by heating to achieve preliminary treatment of the wastewater. The evaporated gas phase material can be further purified or discharged through subsequent treatment. The heat exchange component can adopt a variety of heating methods such as electric heating, steam heating or hot oil circulation. The specific selection needs to be comprehensively considered based on factors such as the nature of the wastewater, treatment efficiency and energy consumption requirements.

[0072] The filter assembly 5 is arranged in the first installation cavity, and is used to filter and discharge the gas phase substances evaporated in the collection assembly 3; the filter assembly 5 is arranged in the first installation cavity, and is mainly used to filter the gas phase substances evaporated in the collection assembly 3 to remove harmful substances or particulate matter therein, and ensure that the discharged gas meets environmental protection standards. The filter assembly can use a variety of high-efficiency filter materials such as activated carbon, molecular sieves, ceramic membranes, etc., and select a suitable filtering method according to the properties of the gas phase substances.

[0073] The control component is used to adjust the working parameters of the suction component 2 and the heat exchange component 4.

[0074] Further, in this embodiment, the suction assembly 2 includes a piston cylinder 2-1, a pair of one-way valves, a piston plate 2-2, a motor 2-3 and a motor connector 2-4; the piston cylinder 2-1 is fixedly installed in the first installation cavity, the input end of the piston cylinder 2-1 is connected to the wastewater of the chemical energy storage prefabricated cabin, and the output end of the piston cylinder 2-1 is connected to the collecting assembly 3; the pair of one-way valves are respectively arranged at both ends of the piston cylinder 2-1; the piston plate 2-2 is arranged in the piston cylinder 2-1, and the piston plate 2- The outer peripheral wall of 2 is slidably connected to the inner peripheral wall of the piston cylinder 2-1; the output shaft of the motor 2-3 is connected to the piston plate 2-2 through the motor connecting piece 2-4, and the connection between the output shaft of the motor 2-3 and the motor connecting piece 2-4 is set as a crankshaft, and the motor connecting piece 2-4 is rotatably connected to the crankshaft; when the motor 2-3 drives the piston plate 2-2 to reciprocate in the piston cylinder 2-1 through the crankshaft and the motor connecting piece 2-4, the wastewater from the chemical energy storage prefabricated cabin is input into the collection component 3.

[0075] A pair of one-way valves are respectively arranged at both ends of the piston cylinder 2-1, playing a key control role. When the piston plate 2-2 moves toward the input end, the one-way valve at the input end opens, allowing wastewater to enter the piston cylinder; at the same time, the one-way valve at the output end closes to prevent wastewater from flowing back. Conversely, when the piston plate 2-2 moves toward the output end, the one-way valve at the input end closes, while the one-way valve at the output end opens, pushing the wastewater into the collection assembly 3. This design ensures that wastewater can only flow in one direction, improving the suction efficiency.

[0076] The motor 2-3 serves as the power source of the suction component, and drives the piston plate 2-2 to reciprocate through its output shaft. This design enables the suction process to be automated, thereby improving work efficiency. The output shaft of the motor 2-3 is connected to the motor connector 2-4 by a crankshaft, and this design can convert the rotational motion of the motor into linear reciprocating motion of the piston plate. The rotational connection between the crankshaft and the motor connector 2-4 ensures the smoothness and reliability of the motion. The working parameters of the motor 2-3 (such as speed, power, etc.) can be precisely adjusted through the control component to meet the needs of different wastewater extraction volumes.

[0077] Further, in this embodiment, the collecting assembly 3 includes a collecting bucket 3-1, a stirring scraper 3-2 and a steering component 3-3;

[0078] The collection barrel 3-1 is arranged in the second installation cavity, and the stirring scraper 3-2 abuts against the inner wall of the bottom of the collection barrel 3-1; the stirring scraper 3-2 abuts against the inner wall of the bottom of the collection barrel 3-1, and is connected to the output shaft of the motor 2-3 through the steering component 3-3. This design enables the stirring scraper 3-2 to automatically rotate while the motor 2-3 is working, scraping and stirring the wastewater sediment at the bottom of the collection barrel, keeping the bottom of the barrel clean, and facilitating the heating of the wastewater. The stirring scraper 3-2 is connected to the output shaft of the motor 2-3 through the steering component 3-3;

[0079] During the movement of the output shaft of the motor 2-3, the stirring scraper 3-2 is driven to rotate on the inner wall of the bottom of the collecting bucket through the steering component 3-3. The steering component 3-3 is a key component connecting the output shaft of the motor 2-3 and the stirring scraper 3-2. It can convert the rotational motion of the motor into the rotational motion of the stirring scraper, and can be a bevel gear set for steering.

[0080] The filter assembly 5 includes an exhaust pipe 5-1 and a filter element; the exhaust pipe 5-1 is arranged in the first installation cavity; a vent hole is arranged on the top of the collection barrel 3-1, and the exhaust pipe 5-1 is connected to the collection barrel 3-1 through the vent hole; a filter element is arranged in the exhaust pipe 5-1, which is used to filter and discharge the vaporized gas phase substances in the collection assembly. The filter element can be arranged at any position in the exhaust pipe 5-1, and the outer peripheral wall of the filter element abuts against the inner peripheral wall of the exhaust pipe 5-1.

[0081] In one embodiment of the present invention, further, the control component is used to adjust the working parameters of the suction component and the heat exchange component, including:

[0082] Construct an evaporation rate model and set the operating temperature of the heat exchange component according to the preset evaporation rate;

[0083] Constructing a water level model, and calculating and obtaining the real-time water level according to the preset evaporation rate and the first water inlet flow rate;

[0084] Calculate and obtain the second water inlet flow rate according to the preset evaporation rate, real-time water level and safe water level;

[0085] The working parameters of the suction component are set according to the second water inlet flow rate.

[0086] The evaporation rate model is expressed using the following formula:

[0087]

[0088] Where E represents the evaporation rate, η represents the efficiency of the heat exchange component, and A evap Represents the surface area of ​​the heat exchange component in contact with the collection component, T in Indicates the operating temperature of the heat exchange component, Tsat It represents the saturation temperature of wastewater under the pressure in the collection barrel, β represents the temperature influence coefficient, P represents the pressure in the collection barrel, and α represents the pressure influence coefficient. The pressure in the collection barrel can be obtained through the pressure measurement tool. The efficiency of the heat exchange component is an important parameter of the performance of the heat exchange component. It reflects the efficiency of the component in transferring heat energy to the wastewater. This parameter can be obtained through experimental measurement. Different heat exchange components have different efficiencies; the saturation temperature is the temperature at which wastewater begins to boil under a certain pressure. It depends on the composition of the wastewater and the pressure in the collection barrel. This parameter can be obtained by consulting relevant thermodynamic data or conducting experimental measurements. The evaporation rate model is used to describe the evaporation process of wastewater in the collection barrel. Its formula takes into account multiple factors such as the efficiency of the heat exchange component, the surface area of ​​the heat exchange component in contact with the collection component, the working temperature of the heat exchange component, and the saturation temperature of the wastewater under the pressure in the collection barrel. Through the preset evaporation rate, the working temperature that the heat exchange component should be set can be inferred to ensure that the wastewater can evaporate at the expected rate.

[0089] The water level model is expressed using the following formula:

[0090]

[0091] Among them, h(t) represents the real-time water level in the collection bucket, h0 represents the initial water level, t represents the time period of working at the first water inlet flow rate, Q in1 (τ) represents the first water inlet flow rate, E represents the evaporation rate, and τ represents the integral parameter. It helps the control system understand the accumulation of wastewater in the collection tank and provides a basis for subsequent water inlet flow rate adjustments.

[0092] The second water inlet flow rate is calculated using the following formula:

[0093]

[0094] Among them, Q in2 Indicates the second water inlet flow rate, h safeRepresents the safe water level, h(t) represents the real-time water level, E represents the evaporation rate, and Δt represents the preset time period. The preset time period is the period for adjusting the inlet flow rate. Ensure that the wastewater can continuously and stably enter the collection bucket for evaporation treatment under the premise of maintaining the safe water level. By building a model and dynamically adjusting the working parameters, the automatic control of the wastewater treatment process is realized, which reduces manual intervention and improves the treatment efficiency and accuracy. Adjusting the inlet flow rate according to the real-time water level and evaporation rate can ensure that the wastewater maintains an appropriate water level in the collection bucket. By accurately controlling the working temperature of the heat exchange component, the energy utilization efficiency can be maximized and unnecessary energy consumption can be reduced. At the same time, the gas phase substances generated by evaporation are filtered and discharged to reduce environmental pollution. Real-time monitoring and dynamic adjustment of working parameters help to promptly discover and deal with potential problems and improve the stability and reliability of the entire wastewater treatment system.
