Abstract
Description
Technical Field
[0001] This utility model relates to the field of glass kiln wall cooling technology, and more specifically, to a cooling system for refractory bricks in glass kiln walls. Background Technology
[0002] Glass furnaces are the core equipment in glass production. Their internal environment is characterized by high temperature, high corrosiveness, and high flow rate. The area near the molten glass surface, in particular, is constantly at the interface of the gas, liquid, and solid phases, enduring extreme temperatures and the continuous erosion of the molten glass. This leads to severe erosion of the upper part of the furnace wall bricks, affecting the furnace's service life and potentially causing accidents such as molten glass leakage. Currently, the industry commonly uses air-cooled systems, which use fans to directly blow air onto the refractory brick surface of the furnace wall for cooling. However, this method suffers from uneven cooling, low efficiency, high energy consumption, and poor cooling effect, making it difficult to effectively meet the cooling requirements of high-temperature environments. Utility Model Content
[0003] The purpose of this invention is to provide a cooling system for refractory bricks in the walls of glass kilns, which solves the problem of poor cooling effect on the walls of glass kilns.
[0004] This utility model is achieved through the following technical solution: a cooling system for refractory bricks in the wall of a glass kiln, comprising boxes respectively arranged on both sides of the kiln, the inner cavity of the box contacting the outer wall of the kiln, a drain pipe for spraying cooling water from top to bottom onto the outer wall of the kiln at the top of the box, a water tank at the bottom of the box, the water tank being connected to an inlet pipe and a drain pipe respectively, an air inlet pipe for blowing cooling air onto the outer wall of the kiln connected to the box, and an exhaust pipe connected to the top of the box.
[0005] Furthermore, an open nozzle is connected to the end of the air inlet pipe. The cooling air in the air inlet pipe enters from the middle of one end of the open nozzle, is compressed and closed by the open nozzle, and is then blown out at an angle downward from the other end of the open nozzle.
[0006] Furthermore, the open-mouth air outlet is arranged horizontally along the length of the kiln.
[0007] Furthermore, a partition is installed inside the box, which divides the box into two interconnected areas along the width of the kiln, and the lower edge of the partition contacts the liquid surface of the water tank.
[0008] Furthermore, the lower edge of the inner wall of the drain pipe is flush with the lower edge of the partition.
[0009] Furthermore, the inner wall of the water-holding pool near the kiln has a slope.
[0010] Furthermore, a ceramic coating is applied to the joint between the slope and the kiln.
[0011] Furthermore, several air inlet ducts are arranged vertically.
[0012] This utility model has at least the following advantages and beneficial effects: by setting boxes on both sides of the glass furnace, the inner cavity of the box is in contact with the outer wall of the furnace, cooling water is sprayed from top to bottom using a downpipe, and cooling air is blown out using an air inlet pipe, thus achieving composite cooling of the refractory bricks of the furnace wall, effectively reducing the temperature of the outer wall of the furnace, improving cooling efficiency, and extending the service life of the refractory bricks of the furnace wall.

[0017] The specific implementation method is described below with reference to the accompanying drawings.
[0018] Example
[0019] like Figures 1 to 3As shown in this embodiment, a cooling system for refractory bricks in the walls of a glass kiln is disclosed. This system is suitable for the wall cooling retrofit of a glass kiln 1 already in operation. The system includes two boxes 2 located on either side of the kiln 1. The inner cavity of the box 2 contacts the outer wall of the kiln 1. A downpipe 3 is installed at the top of the box 2 for spraying cooling water onto the outer wall of the kiln 1 from top to bottom. A water tank 4 is installed at the bottom of the box 2, connected to an inlet pipe 5 and a drain pipe 6. An air inlet pipe 7 is connected to the box 2 for blowing cooling air onto the outer wall of the kiln 1. An exhaust pipe 8 is connected to the top of the box 2. Several boxes 2 can be arranged along the length of the kiln 1; the specific number and location can be determined based on the heat distribution of the kiln 1. The downpipe 3 is connected to an external cooling water supply device and is arranged along the side wall of the kiln 1. Cooling water is sprayed from top to bottom onto the outer wall of the kiln 1 through the downpipe 3, absorbs heat, and then flows into the water tank 4 along the wall surface, avoiding water waste. Additionally, the water tank 4, connected to the inlet pipe 5 and the outlet pipe 6, forms a separate cooling water circulation system. This prevents the water temperature in the water tank 4 from becoming too high, which could lead to water evaporation, affecting the internal environment of the chamber 2 and reducing heat exchange efficiency. Simultaneously, the exhaust pipe 8 is connected to a condenser dehumidifier to promptly remove hot and humid air from the chamber 2, ensuring effective cooling while preventing environmental pollution. By setting chambers 2 on both sides of the glass kiln 1, the inner cavity of the chamber 2 contacts the outer wall of the kiln 1. Cooling water is sprayed from top to bottom using the drain pipe 3, while cooling air is blown through the air inlet pipe 7. This achieves composite cooling of the refractory bricks in the kiln 1 wall, effectively reducing the temperature of the outer wall of the kiln 1, decreasing the thermal stress on the refractory bricks, and extending their service life. Furthermore, by controlling the water inflow through the drain pipe 3 and the inlet pipe 5, as well as the airflow through the air inlet pipe 7 and the exhaust pipe 8, flexible control of the cooling of the kiln 1 wall can be achieved.
[0020] Furthermore, in a specific implementation, the air inlet pipe 7 provided in this embodiment of the present invention is connected to an open nozzle 71 at its end. The cooling air in the air inlet pipe 7 enters from the middle of one end of the open nozzle 71, is compressed and narrowed by the open nozzle 71, and then blows out obliquely downward from the other end of the open nozzle 71. The narrowed outlet of the open nozzle 71 enhances the concentration and impact of the cooling air, making it particularly suitable for localized cooling in high-temperature areas and reducing the erosion of refractory bricks. The downward-sloping air outlet of the open nozzle 71 effectively guides the cooling airflow and accelerates the descent of the cooling water, thereby improving cooling efficiency.
[0021] Preferably, the open-mouthed air outlet 71 is arranged horizontally along the length of the kiln 1. This ensures that the cooling air evenly covers the longer outer wall of the kiln 1, avoiding insufficient cooling in certain areas and further improving the cooling effect.
[0022] Furthermore, in a specific implementation, a partition 21 is provided inside the box 2 provided in this embodiment of the present invention. The partition 21 divides the box 2 into two interconnected areas along the width direction of the kiln 1, and the lower edge of the partition 21 contacts the liquid surface of the water tank 4. Preferably, the lower edge of the inner wall of the drain pipe 6 is flush with the lower edge of the partition 21. Specifically, after the water undergoes heat exchange, it falls into the water tank 4, causing the water level to rise, so that the excess water is discharged from the drain pipe 6, maintaining a constant water level in the water tank 4. The gas after heat exchange carries a lot of heat. After contacting the water in the water tank 4, it undergoes heat exchange and is cooled to a certain extent. Then it is drawn away by the exhaust pipe 8, reducing the workload of the subsequent condensing dehumidifier.
[0023] Furthermore, in a specific implementation, the inner wall of the water-holding pool 4 near the kiln 1 provided in this embodiment of the present invention is provided with a slope 40 to guide cooling water into the water-holding pool 4. The joint between the slope 40 and the kiln 1 is coated with a ceramic coating to enhance the high temperature resistance and corrosion resistance of the joint and prevent cooling water leakage.
[0024] Furthermore, in specific implementation, several air inlet pipes 7 are vertically arranged in the above-mentioned embodiment of the present invention. The density of the air inlet pipes 7 in the vertical direction can be adjusted according to the temperature distribution of the kiln 1, i.e., the cooling requirements. For example, if the temperature of the upper part of the wall is higher, multiple air pipes can be arranged at smaller intervals to ensure that the cooling air is evenly distributed, avoid local overheating, and further improve the cooling effect and service life of the refractory bricks.
