A kiln overflow pool wall brick cooling system

Abstract

A cooling system for the overflow tank wall bricks of a kiln comprises cooling channels, a cooling medium supply device, and a temperature monitoring device arranged on the tank wall bricks. The cooling channels are distributed in a mesh pattern and connected to the cooling medium supply device. The cooling medium supply device delivers cooling medium into the cooling channels through pipes. The cooling medium flows within the channels, absorbs heat from the tank wall bricks, and is then discharged. The temperature monitoring device monitors the temperature changes of the tank wall bricks in real time and feeds the data back to the control system to adjust the flow rate and temperature of the cooling medium. This system aims to prevent serious accidents such as kiln leakage caused by excessively high temperatures leading to molten glass seeping from the joints of the overflow tank wall bricks, thereby extending the service life of the overflow tank wall bricks and reducing equipment maintenance costs.

Description

Technical Field

[0001] This utility model belongs to the field of kiln cooling technology, and specifically relates to a kiln overflow outlet pool wall brick cooling system. Background Technology

[0002] In industries such as metallurgy and chemicals, the overflow outlet of the high-temperature molten pool is one of the critical components of the equipment. Different parts of a glass furnace use different refractory materials and operate in different environments, resulting in significant differences in the degree of corrosion across different parts. The overflow outlet of the branch passage, located at the discharge port, experiences greater longitudinal tension on the molten glass, making it more prone to seeping out from the gaps in the adjacent pool wall bricks than other areas. To prevent premature seepage of molten glass from these areas, which could lead to furnace leakage and forced shutdown, these areas must be cooled.

[0003] Due to its concealed location and limited space, the overflow outlet area of ​​the pool wall lacks a proper cooling system. Because of prolonged contact with the high-temperature molten metal, the wall bricks near the overflow outlet are susceptible to high-temperature erosion and thermal stress damage, leading to cracking, peeling, and even failure. Traditional cooling methods often employ external water or air cooling, but these methods result in uneven cooling and are prone to thermal shock damage to the wall bricks, affecting equipment operating efficiency.

[0004] Therefore, there is an urgent need for a cooling system that can effectively reduce the temperature of pool wall bricks and extend their service life.

[0005] The utility model disclosed in announcement number CN116354586A is a glass melting furnace sidewall atomizing air-cooling system. Its key technical features include an original air-cooling system, a water purification system, a main water pipe, and several branch pipes. Each branch pipe corresponds to a branch air pipe, with one end connected to the main water pipe and the other end connected to the corresponding branch air pipe of the original air-cooling system. Each branch pipe is equipped with a high-pressure nozzle that sprays water mist along the direction of the branch air pipe. The water purification system supplies water to the main water pipe, and the water mist sprayed from the high-pressure nozzles is carried by the airflow to the furnace sidewall. This system modifies the original air-cooling system by adding an atomizing spray function, delivering water mist to the original air-cooling system. While reducing the air temperature, it also delivers water mist to the furnace sidewall, increasing the cooling effect on the furnace wall bricks. However, it still cannot achieve uniform cooling for the concealed overflow outlet area of ​​the furnace wall bricks. Summary of the Invention

[0006] The purpose of this invention is to address the shortcomings of the existing technology by providing a cooling system for the wall bricks of a kiln overflow outlet, optimizing the cooling structure, achieving uniform cooling, reducing thermal stress concentration, and extending the service life of the wall bricks.

[0007] To solve the above technical problems, the technical solution adopted by this utility model is as follows:

[0008] A kiln overflow pool wall brick cooling system includes pool wall bricks, a cooling medium supply device located at the front end of the pool wall bricks, and a temperature monitoring device located inside the pool wall bricks.

[0009] Several cooling channels are cut into the brick walls of the pool, and the cooling channels are distributed in a network and connected to the cooling medium supply device.

[0010] Temperature monitoring devices are installed in the cooling channel to monitor the temperature of the pool wall bricks in real time and feed it back to the control system. The control system is connected to the cooling medium supply device and controls and adjusts the flow rate.

[0011] The cooling medium supply device includes a water pump and water pump pipes connected to both ends of the water pump. A flow regulating valve is also provided on the water pump pipe between the water pump and the cooling channel, and the flow regulating valve is connected to the control system.

[0012] The cooling channels are arranged at intervals, and their diameter and spacing are determined according to the size of the pool wall bricks and the heat load.

[0013] The temperature monitoring device uses a thermocouple.

[0014] Cooling medium is introduced into the water pump pipe at the front inlet of the water pump.

[0015] The cooling medium is water or gas.

[0016] The beneficial effects of this utility model are:

[0017] (1) The kiln overflow pool wall brick cooling system is constructed by arranging cooling channels, cooling medium supply devices, and temperature monitoring devices on the pool wall bricks. The cooling channels are distributed in a mesh pattern and connected to the cooling medium supply devices. The cooling medium supply devices deliver cooling medium into the cooling channels through pipelines. The cooling medium flows in the channels, absorbs the heat of the pool wall bricks, and is then discharged. The temperature monitoring devices monitor the temperature changes of the pool wall bricks in real time and feed the data back to the control system to adjust the flow rate and temperature of the cooling medium. This solves serious accidents such as kiln leakage caused by excessively high temperature glass liquid seeping from the brick joints of the overflow pool wall bricks, extends the service life of the overflow pool wall bricks, and reduces equipment maintenance costs.

[0018] (2) By optimizing the cooling structure, uniform cooling can be achieved, thermal stress concentration can be reduced, and the service life of the pool wall bricks can be extended. Attached Figure Description

[0025] A kiln overflow pool wall brick cooling system includes a pool wall brick 1, a cooling medium supply device 3 located at the front end of the pool wall brick 1, and a temperature monitoring device 4 located inside the pool wall brick; the pool wall brick 1 has several cooling channels 2, which are distributed in a mesh and connected to the cooling medium supply device 3; the temperature monitoring device 4 is installed in the cooling channels 2 to monitor the temperature of the pool wall brick 1 in real time and feed it back to the equipped control system, and the control system is connected to the cooling medium supply device 3 to control and adjust the flow rate.

[0026] The cooling medium supply device 3 includes a water pump 302 and a water pump pipe 301 connected to both ends of the water pump 302. The water pump pipe 301 located between the water pump 302 and the cooling channel 2 is also equipped with a flow regulating valve 303, and the flow regulating valve 303 is connected to the control system.

[0027] The cooling channels 2 are arranged at intervals, and their diameter and spacing are designed according to the size and heat load of the pool wall bricks 1 to ensure uniform cooling of the pool wall bricks 1.

[0028] In this embodiment, the temperature monitoring device uses a thermocouple, which is installed on the surface of the pool wall brick 1 to monitor the temperature change of the pool wall brick in real time and feed the data back to the control system to adjust the flow rate and temperature of the cooling medium.

[0029] Cooling medium is introduced into the water pump pipe 301 at the front inlet of the water pump 302. The cooling medium can be water or gas. The cooling medium flows in the mesh cooling channel 2, absorbs the heat of the pool wall bricks and is then discharged.

[0030] The work process is as follows:

[0031] In use, the cooling medium enters the water pump 302 through the water pump pipe 301, and then passes through the flow regulating valve 303 into the cooling channel 2. The diameter and spacing of the cooling channel 2 are designed according to the size and heat load of the pool wall bricks 1 to ensure uniform cooling of the pool wall bricks 1. The cooling medium enters the cooling channel through the water pump pipe 301, absorbs heat, and is discharged from the outlet.

[0032] Temperature monitoring device 4 uses thermocouples to monitor the temperature of the pool wall bricks 1 in real time and transmits the data to the control system. Based on the temperature monitoring data, flow regulating valve 303 in cooling supply device 3 automatically adjusts the flow rate and temperature of the cooling medium to ensure that the pool wall bricks 1 are within the optimal operating temperature range.
