Description

Technical Field

[0001] This invention relates to the field of ventilation systems and control technology, and more specifically, to an intelligent ventilation and control system for hazardous waste containers. Background Technology

[0002] Currently, hazardous waste containers require ventilation systems to maintain a stable internal environment during the storage and transfer of hazardous waste, in order to avoid safety risks caused by the accumulation of volatile substances and temperature and humidity imbalances. In recent years, with the amount of hazardous waste generated continuing to rise at a compound annual growth rate of approximately 8%, higher demands have been placed on the safety and efficiency of ventilation systems for hazardous waste containers. However, the current technological development in the industry is significantly lagging behind:

[0003] Static ventilation is inefficient: Existing systems mostly use mechanical ventilation at a fixed frequency. Traditional axial flow fans that operate continuously for 24 hours can consume up to 12,000 kWh of electricity per unit per year, far exceeding actual needs. This extensive operation not only wastes energy but also causes premature wear and tear on core components such as fans, increasing maintenance costs.

[0004] Disconnect between environmental perception and response: There is a lack of a real-time monitoring and linkage mechanism for the internal and external environment of the container. During the high-temperature period in summer, the failure to detect the sudden rise in temperature inside the container in time led to the accelerated volatilization of organic solvents, and the peak concentration of VOCs inside the container exceeded the safety threshold by 3 times. In windy weather, the natural ventilation openings of some containers did not automatically adjust their opening, resulting in rainwater backflow and contamination of hazardous waste.

[0005] Insufficient adaptation to hazardous waste characteristics: Different types of hazardous waste have vastly different ventilation requirements. Cyanide-containing hazardous waste requires continuous low-flow ventilation to prevent HCN gas accumulation, while strong acid waste liquid storage requires high-flow ventilation to reduce the risk of acid mist corrosion. Existing systems generally adopt a "one-size-fits-all" ventilation strategy, which cannot meet the differentiated protection needs of hazardous waste.

[0006] The aforementioned technological limitations have led to a common problem in the industry's hazardous waste container ventilation systems: they cannot dynamically adapt and adjust to the specific characteristics of hazardous waste (such as volatility and corrosivity) and real-time internal and external environmental parameters (such as pollutant concentration inside the container and external wind speed and direction). Either they rely on fixed mechanical ventilation modes, resulting in excessive energy consumption, or the switching logic between natural and mechanical ventilation is rigid, making it difficult to achieve high efficiency and energy saving while ensuring safety. Furthermore, they lack adaptability to the differentiated ventilation needs of different types of hazardous waste. Therefore, we propose an intelligent ventilation control system for hazardous waste containers. Summary of the Invention

[0007] The purpose of this invention is to provide an intelligent ventilation and control system for hazardous waste containers, in order to solve the technical problems of traditional hazardous waste container ventilation systems, such as low ventilation efficiency, high energy consumption, inability to dynamically adjust ventilation volume according to the state of hazardous waste, and easy accumulation of harmful gases or waste of resources.

[0087] In the formula, the above formula is established based on the hydrodynamic characteristics of the damper. Indicates the corrected target wind speed , This demonstrates the non-linear effect of damper opening degree on wind speed—the smaller the opening degree, the greater the wind speed decrease. In practical applications, the formula can be calibrated based on the damper model and wind tunnel test data to accurately match equipment performance.

[0088] S403: The third controller is based on the corrected target wind speed. With current wind speed The difference ( Adjust the power of the exhaust unit. The formula is as follows:

Indicates the rate of change of wind speed, when When the wind speed is positive, the system needs to increase its power to improve the wind speed; when When the value is negative, the power is reduced to decrease the wind speed. This formula is derived from the fan power-wind speed characteristic curve. In practical applications, dynamic calibration is required based on the fan model to ensure that the power adjustment meets ventilation needs while avoiding energy waste.
