Description

Technical Field

[0001] This utility model belongs to the field of environmental protection technology, specifically relating to an intelligent automatic start-stop control device for exhaust gas from hazardous chemical warehouses. Background Technology

[0002] Currently, hazardous chemical warehouses are required by environmental regulations to be equipped with environmentally friendly exhaust gas adsorption devices to treat volatile gases generated during storage. However, existing exhaust gas treatment equipment lacks intelligent monitoring and control, resulting in the equipment operating continuously, which leads to a series of problems: Firstly, the continuous operation of the equipment for a long time aggravates the wear and tear of mechanical parts, resulting in a significant increase in the failure rate. This not only increases the equipment maintenance cost, but also poses a hidden danger of environmental and safety risks caused by sudden failures. Secondly, during the summer, the warehouse air conditioning system needs to continuously cool in order to maintain a constant temperature environment. However, the exhaust gas treatment system extracts a large amount of the cooling capacity generated by the air conditioning during indiscriminate operation, resulting in ineffective energy loss and reducing the energy efficiency ratio of the refrigeration equipment. Third, the equipment's 24 / 7 operation generates high energy consumption, with the consumption of electricity and water resources continuously rising, significantly increasing the company's operating costs and creating a long-term economic burden. Utility Model Content

[0003] The purpose of this invention is to provide an intelligent automatic start-stop control device for the exhaust gas of hazardous chemical warehouses, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an intelligent automatic start-stop control device for environmentally friendly exhaust gas in a hazardous chemical warehouse, comprising several VOCs sensors, a linkage controller, and an exhaust fan. The linkage controller is electrically connected to the VOCs sensors and the exhaust fan. A louvered frame is provided on one side of the exhaust fan, and several adjusting blades are rotatably arranged on the louvered frame. Each adjusting blade is connected to a linkage rod, and one adjusting blade is connected to a motor. A heat exchanger is provided on one side of the louvered frame.

[0005] Preferably, the exhaust fan and the heat exchanger are connected by a connecting rod.

[0006] Preferably, the heat exchanger includes a first inlet and a second inlet and a third inlet, and the louvered frame is connected to one of the first inlets and a third inlet.

[0007] Preferably, the second inlet / outlet connection is an extension pipe.

[0008] Preferably, the second inlet and outlet edges are provided with raised flanges, and one end of the extension pipe is provided with a connecting plate, which is locked inside the raised flange.

[0009] The technical effects and advantages of this utility model are as follows: the concentration of harmful gases in the warehouse is monitored in real time by a VOCs sensor, and the start and stop of the exhaust fan is intelligently controlled by a linkage controller; on-demand ventilation is achieved, avoiding the energy waste caused by the long-term ineffective operation of the exhaust fan in the traditional method, and significantly reducing operating costs; The combination of intelligent intermittent operation mode and louver structure can greatly reduce the loss of cold air (or heat) in the warehouse; especially in summer, it can effectively prevent the cold air generated by air conditioning from being discharged in large quantities, maintain the temperature inside the warehouse, thereby reducing the workload of the air conditioning system and further achieving energy saving and consumption reduction. The added plate heat exchanger can exchange heat between the low-temperature air discharged from the warehouse and the high-temperature air entering from the outside; this process pre-cools (in summer) or preheats (in winter) the introduced fresh air, initially reducing the temperature difference of the fresh air, thereby reducing the energy consumed by the subsequent air conditioning system to regulate the temperature of the fresh air. This avoids the continuous operation of the exhaust fan and its power unit, effectively reducing mechanical wear and electrical aging of the equipment through intermittent working mode, extending the service life of the exhaust fan and other related equipment, and reducing maintenance and replacement costs; The extension pipes are connected to the heat exchanger by simple clips and screws, making installation and disassembly convenient. The air outlet positions can be flexibly arranged according to the needs of different areas in the warehouse, ensuring that fresh air can be accurately delivered to the required areas, thus improving ventilation efficiency and application flexibility. While achieving energy-saving goals, the core function ensures that when the concentration of volatile organic compounds in the warehouse exceeds the standard, the exhaust system can be automatically activated in a timely manner to quickly remove dangerous gases, protect warehouse safety and the health of workers, and meet environmental protection requirements.

[0012] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0013] This utility model provides, for example Figure 1 The device shown is an intelligent automatic start-stop control device for exhaust gas in a hazardous chemical warehouse. It includes several VOCs sensors 1, a linkage controller 2, and exhaust fans 3. Each VOCs sensor 1 corresponds to one exhaust fan 3. The linkage controller 2 is electrically connected to the VOCs sensor 1 and the exhaust fan 3. The VOCs sensor 1 detects the gas concentration inside the warehouse. The linkage controller 2 intelligently controls the start and stop of the exhaust fan 3 based on the detection results of the VOCs sensor 1. This can avoid the problem of excessive equipment wear caused by the exhaust fan 3 running for a long time, and also reduce the problem of excessive cold air being discharged in summer, thereby reducing the operating cost.

[0014] like Figure 2 , 3 As shown in Figure 4, in order to further reduce the loss of cold air in the warehouse, this utility model also provides a louver structure and a heat exchanger 4; the louver structure consists of a louver frame 6, adjusting blades 7, a connecting rod 8 and a motor 9. A louver frame 6 is provided on one side of the exhaust fan 3, and several adjusting blades 7 are rotatably arranged on the louver frame 6. Each adjusting blade 7 is connected to the connecting rod 8, and one adjusting blade 7 is connected to the motor 9. The motor 9 drives each adjusting blade 7 to rotate, thereby realizing the opening and closing of the exhaust vent of the exhaust fan 3, which can further reduce the loss of cold air in the warehouse. A heat exchanger 4 is installed on one side of the louvered frame 6. The heat exchanger 4 is a plate heat exchanger. The exhaust fan 3 and the heat exchanger 4 are connected by a connecting rod 5. The heat exchanger 4 includes a heat exchanger shell 41, a first inlet 43 and a second inlet 42. The first inlet 43 and the second inlet 42 are both installed on the heat exchanger shell 41. The louvered frame 6 connects to one of the first inlet 43. The first inlet 43 is the gas exhaust channel in the warehouse. The second inlet 42 is the channel for external gas to enter the warehouse. The exhaust gas in the warehouse and the external air entering the warehouse exchange heat in the heat exchanger 4, which can initially reduce the temperature of the gas entering the warehouse and appropriately reduce the energy consumption of air conditioning in summer, thus reducing costs. The second inlet 42 is connected to an extension pipe 11, which can be extended to the required location in the warehouse as needed.

[0015] Specifically, the second inlet / outlet 42 has a raised edge, and a connecting plate 10 is provided at one end of the extension pipe 11. The connecting plate 10 is inserted into the raised edge and fixed with screws, which can realize the simple installation of the extension pipe 11.
