Technical Field

[0001] The invention belongs to the technical field of glass production, and in particular relates to a cooling system and a cooling method for a space inside a small furnace aisle of a glass melting furnace. Background Art

[0002] In the traditional glass production process, the temperature on both sides of the melting furnace is extremely high, and the environment for workers to inspect and operate is harsh. In the small furnace aisle, the heat storage chamber, small furnace and melting part of the glass melting furnace surround the small furnace aisle, making the environment in this space even worse. Therefore, there is an urgent need for a cooling system that can be used in the space inside the small furnace aisle to improve the workers' inspection and operating environment.

[0003] At present, some glass melting furnaces at home and abroad have added a pair of bottom plate water bags under the bottom plate of the small furnace. The bottom plate water bags can be used to block the heat radiation from the direction of the small furnace, but they can hardly block the heat radiation from the heat storage chamber and melting part of the glass melting furnace. The operating environment of the space inside the small furnace aisle is still poor. Workers often wear cotton jackets or protective clothing during inspections and operations to resist the extremely high temperature environment, which makes them prone to heat stroke and skin diseases.

[0004] As companies have paid more and more attention to the working environment of workers in recent years, how to ensure stable production of glass melting furnaces while effectively improving the operating environment of the space inside the small furnace aisle and reducing the probability of workers suffering from occupational diseases, thereby improving the company's worker protection and promoting the company's high-quality development, is a problem that more and more glass production companies are currently concerned about.

The cooling system for the inner space of a small furnace of a glass melting furnace according to claim 1, characterized in that: Mounting brackets (11) are fixed at the four corners of the bottom surface of the bottom plate of the distribution box (13), and each mounting bracket (11) is fixedly connected to a small furnace bottom frame (821). The small furnace bottom frame (821) is located below the small furnace bottom plate and is fixedly connected to the small furnace bottom plate.

8. A method for cooling the space inside the aisle of a small furnace of a glass melting furnace, using the cooling system for the space inside the aisle of a small furnace of a glass melting furnace as claimed in any one of claims 1 to 7, characterized in that: The following steps are involved: S1, cooling air enters the cooling air temperature regulating pipe (21) from the cooling air main pipe (7), and cooling water is supplied to the heat exchange water network pipe (24) through the water inlet pipe (22), the cooling water in the heat exchange water network pipe (24) performs heat exchange with the cooling air entering the cooling air temperature regulating pipe (21) to reduce the temperature of the cooling air, and the return water in the heat exchange water network pipe (24) after heat exchange is discharged to the outside through the water outlet pipe (23); S2. The cooling air with a reduced temperature discharged from the cooling air temperature regulating pipe (21) enters the distribution box (13) through the air inlet (12) and is blown toward the space in the small furnace aisle through the air outlet (14) to cool the space in the small furnace aisle.

9. A method for cooling the space in the aisle of a glass melting furnace according to claim 8, characterized in that: In step S1: the temperature of the cooling air entering the cooling air temperature regulating pipe (21) is measured. When the temperature of the cooling air in the cooling air temperature regulating pipe (21) is high, the cooling water flow rate entering the water inlet pipe (22) is increased, and the return water flow rate in the water outlet pipe (23) is increased. The cooling water temperature in the water inlet pipe (22) is adjusted by measuring the cooling water temperature in the water inlet pipe (22).
