Description

Technical Field

[0001] The utility model relates to the technical field of metallurgical furnaces, and particularly relates to an automatically adjustable water mist cooling and temperature reducing device. Background Art

[0002] In the production process of the smelting industry, the operating conditions of traditional metallurgical furnaces are placed in a high-temperature environment. The furnace body and its accessories are prone to mechanical wear and erosion by high-temperature fluids, resulting in a shortened service life. At the same time, due to the harsh operating environment of the metallurgical furnace placed in a high temperature, the on-site operators cannot obtain real-time and effective data on the heating conditions inside the furnace. Therefore, cooling the boiler is a crucial link in the metallurgical industry.

[0003] The traditional furnace kiln and melt cooling and temperature reduction mainly rely on forced ventilation and natural cooling. However, these two cooling methods have a long cooling time, a slow cooling rate, and are greatly affected by external factors such as environmental temperature and humidity. If direct cooling water or water mist is used for temperature reduction, it is necessary to manually monitor the temperature status in real time and then control the cooling water or water mist for temperature reduction. The overall operation is troublesome, time-consuming and laborious. Moreover, in the continuous production process of the metallurgical furnace, if the furnace body is not cooled in a timely and effective manner, the furnace body is prone to leakage and rupture, and it is not conducive to production temperature control, thus the furnace condition cannot be effectively adjusted, and the qualified rate of the sintered products will also drop significantly, causing unnecessary economic losses. Summary of the Utility Model

[0004] The purpose of the utility model is to provide an automatically adjustable water mist cooling and temperature reducing device with good cooling effect, high automation degree, convenient operation and high safety, so as to solve the technical problems of troublesome operation, low safety, time-consuming and laborious when cooling the furnace body in the prior art.

[0005] In order to solve the above technical problems, the following solutions are adopted in the utility model:

[0006] An automatically adjustable water mist cooling and temperature reducing device includes a nitrogen supply device, a cooling water supply device, an atomizing nozzle, a water mist pipeline and a temperature detection device; one end of the nitrogen supply device is connected to one end of the atomizing nozzle, and the other end is sealed at the tail; one end of the cooling water supply device passes through the nitrogen supply device and is connected to one end of the atomizing nozzle; the other end of the atomizing nozzle is connected to the water mist pipeline. The nitrogen supply device supplies nitrogen to atomize the cooling water supplied by the cooling water supply device, and then sprays it into the water mist pipeline through the atomizing nozzle. The water mist pipeline is connected to the water jacket and enters the water jacket of the furnace body from the water mist pipeline to cool and reduce the temperature of the furnace body; the temperature detection device is fixedly installed in the water mist pipeline to detect the temperature inside the water jacket in real time.

[0007] The nitrogen supply device includes a nitrogen gas supply point pipeline, a self-controlled nitrogen gas flow control valve, a nitrogen connection hose, and a supply pipe. One end of the self-controlled nitrogen gas flow control valve is connected to the nitrogen gas supply point pipeline, and the other end is connected to one end of the nitrogen connection hose, which is used to control the nitrogen gas flow from the nitrogen gas supply point pipeline to the nitrogen connection hose. The other end of the nitrogen connection hose is connected to the supply pipe.

[0008] The cooling water supply device includes a cooling water supply point pipeline, a self-controlled water flow control valve, and a supply pipe. One end of the self-controlled water flow control valve is connected to the cooling water supply point pipeline, and the other end is connected to the supply pipe. The temperature detection device is connected to the self-controlled water flow control valve and the self-controlled nitrogen control valve, and fine control and adjustment are carried out through an external control device connected to the temperature detection device.

[0009] Furthermore, the supply pipe includes a nitrogen connection pipe and a nitrogen-passing pipe. One end of the nitrogen connection pipe is connected to the nitrogen connection hose, and the other end is connected to the nitrogen-passing pipe. One end of the nitrogen-passing pipe is connected to the atomizing nozzle, and the other end is sealed at the tail. After the nitrogen gas flows to the nitrogen connection hose, it flows into the nitrogen-passing pipe through the nitrogen connection pipe. The nitrogen-passing pipe is connected to the atomizing nozzle, and the nitrogen gas is transported to the atomizing nozzle to atomize the cooling water supplied by the cooling water supply device.

[0010] Furthermore, the nitrogen-passing pipe and the nitrogen connection pipe are vertically connected. The vertical connection of the nitrogen-passing pipe and the nitrogen connection pipe facilitates the supply pipe to pass through the nitrogen-passing pipe and be connected to the atomizing nozzle to atomize the cooling water during the process of using the atomizing nozzle for cooling.

[0011] Furthermore, the supply pipe includes a cooling water connection hose and a water-passing pipe. One end of the cooling water connection hose is connected to the self-controlled water flow control valve, and the other end is connected to one end of the water-passing pipe. The other end of the water-passing pipe is connected to the atomizing nozzle. After the cooling water flows to the cooling water connection hose, it flows into the water-passing pipe through the cooling water connection hose. The water-passing pipe is connected to the atomizing nozzle to transport the cooling water to the atomizing nozzle for atomization operation.

[0013] The upper and lower limits of the temperature setting of the temperature detection device equipped in the water mist pipeline. The temperature detection device is connected to the self-controlled water flow control valve and the self-controlled nitrogen control valve. It receives the temperature of the temperature detection device in real time through an external control device. The temperature detection device monitors the temperature of the water jacket in real time. Cooling water flows from the cooling water supply point pipeline into the cooling water connection hose and the water pipe after the water supply is controlled by the self-controlled water flow control valve. Nitrogen enters the nitrogen connection hose, the nitrogen connection pipe and the nitrogen pipe through the nitrogen supply point pipeline after the gas supply is controlled by the self-controlled nitrogen control valve 2. Finally, both nitrogen and cooling water enter the atomizing nozzle, and the atomizing nozzle atomizes the cooling water with nitrogen.

[0014] When the measured temperature is higher than the set upper limit value, control the self-controlled water flow control valve and the self-controlled nitrogen flow control valve to increase the water flow and nitrogen flow, so as to increase the water mist ejected by the atomizing nozzle. After the water mist particles contact the high-temperature surface, they quickly evaporate and absorb a large amount of heat, thus achieving rapid cooling and cooling the furnace body. When it reaches the lower limit, control the self-controlled water flow control valve and the self-controlled nitrogen flow control valve to stop delivering cooling water and nitrogen to avoid the temperature of the furnace body being too low.

[0015] The beneficial effects of the present utility model are as follows:

[0016] 1. The temperature detection device of the present utility model is fixedly installed in the water mist pipeline, which can monitor the temperature of the cooling area in real time. By setting the upper and lower limits of the temperature detected by the temperature detection device, the temperature detection device is connected to the self-controlled water flow control valve and the self-controlled nitrogen control valve, and the valves are controlled through an external control device, and then the flow rates of the cooling water and nitrogen are controlled to adjust the size of the water mist ejected by the atomizing nozzle to cool the furnace body, ensuring the stability and accuracy of the cooling effect.

[0017] 2. The nitrogen supply device of the present utility model transports nitrogen to the atomizing nozzle through the nitrogen connection hose, the nitrogen connection pipe and the nitrogen pipe, combines with the cooling water provided by the cooling water supply device for atomization treatment, improves the atomization efficiency of the cooling water, and enhances the diffusion range and cooling effect of the water mist through the auxiliary action of nitrogen, so as to achieve the purpose of rapid and uniform cooling and temperature reduction.

[0022] The following will further describe in detail an automatically adjustable water mist cooling and temperature reduction device of the present utility model in conjunction with the accompanying drawings: Embodiment 1

[0023] An automatically adjustable water mist cooling and temperature reduction device includes a nitrogen supply device, a cooling water supply device, an atomizing nozzle 10, a water mist pipeline 11, and a temperature detection device 12; one end of the nitrogen supply device is connected to one end of the atomizing nozzle 10, and the other end is sealed at the tail; one end of the cooling water supply device passes through the nitrogen supply device and is connected to one end of the atomizing nozzle 10; the other end of the atomizing nozzle 10 is connected to the water mist pipeline 11; the temperature detection device 12 is fixedly installed in the water mist pipeline 11;

[0024] The nitrogen supply device includes a nitrogen gas supply point pipeline 1, an automatic nitrogen gas flow control valve 2, a nitrogen gas connection hose 3, and a gas supply pipe; one end of the automatic nitrogen gas flow control valve 2 is connected to the nitrogen gas supply point pipeline 1, and the other end is connected to one end of the nitrogen gas connection hose 3; the other end of the nitrogen gas connection hose 3 is connected to the gas supply pipe;

[0025] The cooling water supply device includes a cooling water supply point pipeline 5, a self-controlled water flow control valve 6, and a water supply pipe; one end of the self-controlled water flow control valve 6 is connected to the cooling water supply point pipeline 5, and the other end is connected to the water supply pipe; the temperature detection device 12 is connected to the self-controlled nitrogen flow control valve 2 and the self-controlled water flow control valve 6.

[0026] The working principle of this embodiment is as follows:

[0027] When used for the water jacket of the flash furnace, the temperature detection device 12 equipped in the water mist pipeline sets the upper and lower limits of the internal temperature of the water jacket. The upper limit temperature is 65°C, and the lower limit temperature is 45°C. The temperature detection device 12 is connected to the self-controlled water flow control valve 6 and the self-controlled nitrogen control valve 2. The temperature of the temperature detection device 12 is received in real time through an external control device. The cooling water flows from the cooling water supply point pipeline 5 into the water supply pipe after the water supply amount is controlled by the self-controlled water flow control valve 6. Nitrogen enters the nitrogen connection hose 3 and the air supply pipe from the nitrogen supply point pipeline 1 through the control of the air supply amount by the self-controlled nitrogen control valve 2. Finally, both nitrogen and cooling water enter the atomizing nozzle 10. The atomizing nozzle 10 atomizes the cooling water with nitrogen. When the measured temperature in the water jacket is higher than the set upper limit value of 65°C, the self-controlled water flow control valve 6 and the self-controlled nitrogen flow control valve 2 are controlled to increase the water flow and nitrogen flow, so that the water mist sprayed by the atomizing nozzle 10 increases. After the water mist particles contact the high-temperature surface, they quickly evaporate and absorb a large amount of heat, thereby achieving rapid cooling and cooling the furnace body. When the temperature reaches or is lower than the lower limit temperature of 45°C, the self-controlled water flow control valve 6 and the self-controlled nitrogen flow control valve 2 are controlled to stop supplying cooling water and nitrogen to avoid the temperature of the furnace body being too low. Embodiment 2

[0028] The difference from Embodiment 1 is that the air supply pipe includes a nitrogen connection pipe 4 and a nitrogen supply pipe 9; one end of the nitrogen connection pipe 4 is connected to the nitrogen connection hose 3, and the other end is connected to the nitrogen supply pipe 9; one end of the nitrogen supply pipe 9 is connected to the atomizing nozzle 10, and the other end is sealed at the tail; the nitrogen supply pipe 9 and the nitrogen connection pipe 4 are vertically connected; the water supply pipe includes a cooling water connection hose 7 and a water passing pipe 8; one end of the cooling water connection hose 7 is connected to the self-controlled water flow control valve 6, and the other end is connected to one end of the water passing pipe 8; the other end of the water passing pipe 8 is connected to the atomizing nozzle 10.

[0029] After the nitrogen gas flows to the nitrogen connection hose 3, it flows through the nitrogen connection pipe 4 into the nitrogen supply pipe 9. The nitrogen supply pipe 9 is connected to the atomizing nozzle 10 to deliver the nitrogen gas to the atomizing nozzle 10. After the cooling water flows to the cooling water connection hose 7, it flows through the cooling water connection hose 7 into the water supply pipe 8. The water supply pipe 8 passes through the inside of the nitrogen supply pipe 9 and is connected to the atomizing nozzle 10. The nitrogen supply pipe 9 is vertically connected to the nitrogen connection pipe 4.

The atomizing nozzle 10 atomizes the cooling water delivered by the water supply pipe 8 by using the nitrogen gas delivered by the nitrogen supply pipe 9 to cool the furnace body.

[0030] The working principle of this embodiment is the same as that of Embodiment 1.
