[0064] The present invention will be described in more detail below with reference to the accompanying drawings. In each of the accompanying drawings, identical elements are represented by similar reference numerals. For the sake of clarity, the various parts in the accompanying drawings are not drawn to scale.

[0065] Example 1

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

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

[0068] The shell 1 is mounted outside the prefabricated chemical energy storage chamber. A first installation cavity and a second installation cavity are arranged vertically within the shell 1. Shell 1 forms the main structure of the wastewater collection device and is located outside the prefabricated chemical energy storage chamber to isolate the treatment process from other equipment within the chamber, ensuring safe operation. The interior of the shell is divided into a first installation cavity and a second installation cavity. This vertically layered design not only optimizes space utilization but also facilitates the installation, maintenance, and overhaul of various components.

[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 interior 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] A collection assembly 3 is installed within the second installation cavity, connected to the output end of the suction assembly 2. Located within the second installation cavity, the collection assembly 3 receives and temporarily stores wastewater extracted from the suction assembly 2. Its design must consider the wastewater's volume, fluidity, and potential sedimentation. The collection assembly 3 may be constructed of corrosion-resistant materials and equipped with monitoring equipment such as a liquid level sensor to ensure timely monitoring of wastewater storage conditions and enable appropriate treatment measures.

[0071] A heat exchange assembly 4 is located below and outside the collection assembly 3. It is used to heat the liquid within the collection assembly 3. Heat exchange assembly 4, located below and outside the collection assembly 3, promotes evaporation of water from the wastewater through heating, achieving initial wastewater treatment. The evaporated gaseous substances can be further purified or discharged through subsequent treatment. The heat exchange assembly can utilize various heating methods, including electric heating, steam heating, or hot oil circulation. The specific selection should be based on a comprehensive consideration of factors such as the wastewater properties, treatment efficiency, and energy consumption requirements.

[0072] The filter assembly 5 is disposed within the first mounting cavity and is used to filter and discharge vaporized gaseous matter from the collection assembly 3. The filter assembly 5 is disposed within the first mounting cavity and is primarily used to filter vaporized gaseous matter from the collection assembly 3 to remove harmful substances and particulate matter, ensuring that the discharged gas meets environmental standards. The filter assembly can utilize a variety of high-efficiency filter materials, such as activated carbon, molecular sieves, and ceramic membranes, with the appropriate filtration method selected based on the properties of the gaseous matter.

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

[0074] Furthermore, 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 collection 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- 2 is slidably connected to the inner circumferential 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 connector 2-4, and the connection between the output shaft of the motor 2-3 and the motor connector 2-4 is set as a crankshaft, and the motor connector 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 connector 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, located at either end of piston cylinder 2-1, play a crucial role in controlling the flow of wastewater. When 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. Simultaneously, the one-way valve at the output end closes, preventing wastewater from flowing back. Conversely, when 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 wastewater into collection assembly 3. This design ensures that wastewater can only flow in one direction, improving 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. 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 movement. The operating 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] Furthermore, 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 disposed within the second mounting 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 via the steering component 3-3. This design allows the stirring scraper 3-2 to automatically rotate while the motor 2-3 is operating, scraping and stirring the wastewater sediment at the bottom of the collection barrel, keeping the bottom clean and facilitating wastewater heating. The stirring scraper 3-2 is connected to the output shaft of the motor 2-3 via the steering component 3-3.

[0079] During the movement of the output shaft of the motor 2-3, the stirring blade 3-2 is driven to rotate on the inner wall of the bottom of the collection bucket via 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 blade 3-2. It can convert the rotational motion of the motor into the rotational motion of the stirring blade, 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 disposed within the first mounting cavity. A vent is provided at the top of the collection barrel 3-1, through which the exhaust pipe 5-1 communicates with the collection barrel 3-1. A filter element is disposed within the exhaust pipe 5-1 to filter and discharge vaporized matter from the collection assembly. The filter element can be positioned anywhere within the exhaust pipe 5-1, with its outer circumferential wall abutting against the inner circumferential 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 a 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 based on the preset evaporation rate, real-time water level and safe water level;

[0085] The operating 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 Indicates 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 represents the saturation temperature of the wastewater at the pressure within the collection tank, β represents the temperature influence coefficient, P represents the pressure within the collection tank, and α represents the pressure influence coefficient. The pressure within the collection tank can be measured using a pressure measurement tool. Heat exchanger efficiency is a key performance parameter of a heat exchanger. It reflects how efficiently the component transfers heat energy to the wastewater. This parameter can be determined experimentally, and different heat exchangers 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 within the collection tank. This parameter can be obtained by consulting relevant thermodynamic data or conducting experimental measurements. The evaporation rate model describes the evaporation process of wastewater within the collection tank. Its formula takes into account multiple factors, including the efficiency of the heat exchanger, the surface area of ​​contact between the heat exchanger and the collection tank, the operating temperature of the heat exchanger, and the saturation temperature of the wastewater at the pressure within the collection tank. Using the preset evaporation rate, the desired operating temperature of the heat exchanger can be inferred to ensure that the wastewater evaporates 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 inlet flow rate, E represents the evaporation rate, and τ represents the integral parameter. This helps the control system understand the accumulation of wastewater in the collection tank and provides a basis for subsequent inlet flow rate adjustments.

[0092] The second 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. This ensures that wastewater can continuously and stably enter the collection tank for evaporation while maintaining the safe water level. By building a model and dynamically adjusting operating parameters, automated control of the wastewater treatment process is achieved, reducing manual intervention and improving treatment efficiency and accuracy. Adjusting the inlet flow rate based on the real-time water level and evaporation rate ensures that the wastewater maintains an appropriate level in the collection tank. Precisely controlling the operating temperature of the heat exchange components maximizes energy efficiency and reduces unnecessary energy consumption. Furthermore, the gaseous substances produced by evaporation are filtered and discharged, reducing environmental pollution. Real-time monitoring and dynamic adjustment of operating parameters help to promptly identify and address potential problems, improving the stability and reliability of the entire wastewater treatment system.
