[0002] In southern my country, basic detonators (semi-finished products) for civil explosives need to be stored in a constant temperature and moisture-proof storage warehouse during the storage process. The existing heating method is boiler steam heating, which forms steam by heating water to about 70℃-80℃ under a certain pressure and is transported to the radiator in the temporary storage warehouse, thereby heating and controlling the room temperature in the temporary storage warehouse and achieving the effect of constant temperature in the temporary storage warehouse. However, with the continuous development of energy conservation and consumption reduction in enterprises, this heating method was soon cancelled. The other existing heating methods are to use electricity to heat water through various methods and equipment to obtain heat energy for heating.

[0003] However, practice has shown that the existing heating methods have the following problems: First, the efficiency of electric heating is low. The electric heating method needs to convert electrical energy into thermal energy and then transfer it to the temporary storage warehouse. There is energy conversion loss, so the overall efficiency is low. It may cause the room temperature in the temporary storage warehouse to rise slowly, or the temperature cannot reach the required constant temperature level, affecting the storage quality of basic detonators for civil explosives; second, due to the generally high price of electricity, the heating cost will increase, which has a certain impact on the economic benefits of the enterprise.

DETAILED DESCRIPTION

[0022] A waste heat recovery energy-saving system for basic detonator temporary storage, as shown in the attached Figure 1 As shown, it includes an air compressor room and a temporary storage warehouse. An air compressor is arranged in the air compressor room. A radiator 1 is arranged in the temporary storage warehouse. It also includes a heat exchanger 2, a cooling device, and a controller. The air compressor is connected to the cooling device through the heat exchanger 2.

[0023] The heat exchanger 2 includes a cold flow channel and a hot flow channel, and the cooling pipe of the air compressor is connected to the hot flow channel;

[0024] The cooling device includes an insulated water tank 3 arranged outside the air compressor room and at a position higher than the air compressor, the water outlet end I of the insulated water tank 3 is connected to the water inlet end of the cold flow channel through a water supply pipe I4, the water inlet end I of the insulated water tank 3 is connected to the water outlet end of the cold flow channel through a return pipe I5, a water pump I6 and a solenoid valve I7 are arranged on the return pipe I5, and the solenoid valve I7 is located between the water pump I6 and the insulated water tank 3; the water outlet end II of the insulated water tank 3 is connected to the water inlet end of the radiator 1 through a water supply pipe II8, a water pump II9 and a solenoid valve II10 are arranged on the water supply pipe II8, and the solenoid valve II10 is located between the water pump II9 and the water inlet end of the radiator 1, and the water inlet end II of the insulated water tank 3 is connected to the water outlet end of the radiator 1 through a return pipe II11;

[0025] The water pump I6, the solenoid valve I7, the water pump II9 and the solenoid valve II10 are all electrically connected to the controller.

[0026] The combined structural design of the radiator 1, the heat exchanger 2, the cooling device and the controller in the utility model realizes energy-saving heating of the basic detonator temporary storage by effectively utilizing the waste heat generated by the air compressor, wherein the combined structural design of the insulated water tank 3, the water supply pipe Ⅰ4, the heat exchanger 2, the return pipe Ⅰ5, the water pump Ⅰ6 and the solenoid valve Ⅰ7 realizes the water supply heating cycle and recovers the waste heat generated by the air compressor; the combined structural design of the radiator 1, the insulated water tank 3, the water supply pipe Ⅱ8, the water pump Ⅱ9, the solenoid valve Ⅱ10 and the return pipe Ⅱ11 realizes the heating cycle; the water supply heating cycle and the heating cycle together form a closed-loop system to ensure the recycling of thermal energy and improve the energy utilization efficiency. Compared with electric heating, the use of waste heat for heating reduces the heating cost, thereby reducing the operating cost of the enterprise, while reducing the dependence on electric energy and having a positive impact on the environment.

[0027] The volume of the thermal insulation water tank 3 is 1m³.

[0028] A visual water level sensor is installed on the thermal insulation water tank 3, and the visual water level sensor is electrically connected to the controller.

[0029] The structural design of the visual water level sensor can monitor the water level in the insulated water tank 3 in real time. When the water level in the insulated water tank 3 is higher or lower than the set water level range, the controller will control water pump I6 and water pump II9 to stop working to prevent the insulated water tank 3 and the system from being damaged due to excessively high or low water levels, thereby protecting the system.

[0030] The insulated water tank 3 is provided with a temperature sensor I, and the temperature sensor I is electrically connected to the controller.

[0031] The structural design of the temperature sensor Ⅰ can monitor the hot water temperature in the insulated water tank 3 in real time. When it reaches the set temperature, the temperature signal at this time is transmitted to the controller in time, so that the controller controls the solenoid valve Ⅱ10 to open and the water pump Ⅱ9 to start; when it does not reach the set temperature, the temperature signal at this time is transmitted to the controller in time, so that the controller controls the solenoid valve Ⅱ10 to close and the water pump Ⅱ9 to stop working.

[0032] A temperature sensor II is installed on the inner wall of the temporary storage, and the temperature sensor II is electrically connected to the controller.

[0033] The structural design of temperature sensor II plays the role of real-time monitoring of the room temperature in the temporary storage warehouse, ensuring that the room temperature reaches the required room temperature requirements in the temporary storage warehouse, thereby ensuring the storage quality of basic detonators for civil explosions.

[0034] As attached Figure 1 As shown, an electronic descaling device 12 is provided on the water supply pipe Ⅰ4, and the electronic descaling device 12 is located between the insulated water tank 3 and the water inlet end of the cold flow channel.

[0035] The structural design of the electronic descaling device 12 can remove scale passing through the electronic descaling device 12, thereby preventing the cold flow channel and the hot flow channel in the heat exchanger 2 from being blocked by scale.

[0036] As attached Figure 1 As shown, a filter 13 is provided on the return pipe Ⅰ5, and the filter 13 is located between the water pump Ⅰ6 and the water outlet end of the cold flow channel.

[0037] The structural design of the filter 13 can filter out impurities in the water passing through the filter 13 to protect the water supply pipe I4, return pipe I5, water supply pipe II8, return pipe II11, water pump I6, and water pump II9 in the system from blockage, thereby ensuring the normal operation of the system.

[0038] The filter 13 is a Y-type filter.

[0039] A buffer water tank with a volume of 400L is installed on the return water pipe II11, and the buffer water tank is located near the outside of the temporary storage warehouse.

[0040] The structural design of the buffer water tank plays the role of exhaust buffer for the system, avoiding the accumulation of air in the pipeline in the radiator 1 due to the long-distance transportation of hot water, thereby affecting the heat dissipation effect.

[0041] During operation, cold water is stored in the insulated water tank 3. When the water level in the insulated water tank 3 is within the set range, the visual water level sensor transmits the water level signal at this time to the controller, so that the controller controls the solenoid valve Ⅰ7 to open and the water pump Ⅰ6 to start. The cold water flows from the outlet end Ⅰ of the insulated water tank 3 along the water supply pipe Ⅰ4 through the high head difference through the electronic descaling device 12 and enters the cold flow channel. After absorbing the waste heat of the air compressor, it is heated to hot water. Then, the hot water is filtered through the filter 13 from the outlet end of the cold flow channel along the return pipe Ⅰ5 and then pumped back to the insulated water tank 3 under pressure through the water pump Ⅰ6, thereby forming a water supply heating cycle. The hot water temperature, when it does not reach 65 ℃, the controller controls the solenoid valve Ⅱ10 to close and the water pump Ⅱ9 to stop working; when it reaches 65 ℃, the controller controls the solenoid valve Ⅱ10 to open and the water pump Ⅱ9 to start, and then the hot water in the insulated water tank 3 is pumped along the water supply pipe Ⅱ8 by the water pump Ⅱ9 to the radiator 1 in the temporary storage to heat the temporary storage, and then the hot water flows from the water outlet of the radiator 1 along the return pipe Ⅱ11 through the buffer water tank back to the insulated water tank 3, thereby forming a closed loop of the system, thereby completing the waste heat recovery heating work of the system; overcoming the problems of large energy conversion loss in the existing heating method, resulting in low heating efficiency and high heating cost.

[0042] It should be noted that, according to process requirements, the temperature required for drying and moisture-proofing the items stored in the temporary storage is generally controlled between 35°C and 40°C. Therefore, in order to meet the heating requirements, the hot water temperature in the insulated water tank 3 must reach 75°C or above. When the hot water temperature in the insulated water tank 3 reaches 65°C, the water heating cycle will continue to heat the hot water, so that the hot water temperature in the insulated water tank 3 will eventually reach 75°C, thereby meeting the heating requirements.
