Water cooling system for melting furnace

Abstract

This utility model discloses a water-cooling device for a melting furnace, including a water-cooling pool surrounding the furnace wall. The water-cooling pool is connected to a water storage tank via a circulating pump. The water-cooling pool includes multiple turbulence-inducing units connected in series and turbulence-inducing columns connected to each corresponding turbulence-inducing unit. One sidewall of each turbulence-inducing unit abuts against the furnace wall. The connection between two adjacent turbulence-inducing units narrows, and the gap between the turbulence-inducing unit and the turbulence-inducing column forms a water flow channel. By setting up turbulence-inducing units in combination with turbulence-inducing columns and narrowing the connection, the water flow in the water-cooling pool can more easily form turbulence during flow, thereby achieving better heat exchange with the furnace wall. Furthermore, due to the high specific heat capacity of water, it can absorb more heat, effectively cooling the furnace wall, reducing energy consumption, and also reducing the floor space required.

Description

Technical Field

[0001] This utility model relates to the field of microcrystalline glass production technology, and in particular to a water-cooling device for a melting furnace. Background Technology

[0002] In the production of microcrystalline glass, the mixture needs to be melted at high temperatures in a furnace to form molten glass. During the melting process, the furnace temperature can rise above 1300℃. To mitigate the erosion of the furnace walls, including the pool wall bricks and electrode bricks, by the molten glass and extend the furnace's service life, cooling treatment of the furnace walls is necessary.

[0003] Traditional cooling systems use several outlets to blow cooling air, each with a circular nozzle. The direction and speed of the airflow are fixed, creating dead zones in the cooling area. This results in uneven temperatures on the furnace wall bricks and electrode bricks, leading to severe erosion of the poorly cooled furnace wall bricks. Furthermore, the uneven temperature on the furnace wall surface causes uneven temperatures inside the furnace, affecting the melting quality of the molten glass.

[0004] To address the aforementioned technical problems, existing technologies, such as the furnace wall cooling device disclosed in patent application CN202421120378.0, include a pressure equalization air box, an air supply pipeline, a first air supply component, and a second air supply component. The pressure equalization air box has several pressure equalization air outlets; the outlet end of the air supply pipeline is connected to the pressure equalization air box; the first air supply component is located in the air supply pipeline and is used to supply gas to the pressure equalization air box; several second air supply components are provided, with their inlets respectively connected to several pressure equalization air outlets; the air outlets of the several second air supply components are dispersedly arranged, and the air flowing out of each second air supply component's outlet forms an air outlet surface that can cover the entire furnace wall. This air outlet surface is the intersection of the air flowing out of each second air supply component's outlet and the plane of the furnace wall. This arrangement improves the uniformity of furnace wall cooling, increases the lifespan of the furnace wall bricks, and enhances the melting quality of the molten glass.

[0005] However, the above technical solutions still have some technical defects: In order to continuously cool the furnace wall, a large amount of air needs to be blown on the furnace wall continuously, which requires a huge air volume, that is, a high-power fan. This is extremely energy-consuming during long-term use. At the same time, multiple air-cooling devices will lead to a significant increase in the overall footprint. Utility Model Content

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.

[0027] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0028] refer to Figure 1 as well as Figure 2 As shown, the water-cooling device for a melting furnace according to an embodiment of the present invention includes a water-cooling pool arranged around the furnace wall 100. The water-cooling pool is connected to a water storage pool (not shown in the figure) through a circulating pump (not shown in the figure). The water-cooling pool includes a plurality of turbulence-inducing units connected in series and turbulence-inducing columns 220 connected to the corresponding turbulence-inducing units. One side wall of the turbulence-inducing unit abuts against the furnace wall 100. The connection between two adjacent turbulence-inducing units narrows. The gap between the turbulence-inducing unit and the turbulence-inducing column 220 forms a water flow channel.

[0029] In practical use, by setting up a turbulence unit in conjunction with a turbulence column 220 and narrowing the connection, the water flow in the water-cooled pool can more easily form turbulence during the flow process, thereby enabling better heat exchange with the furnace wall 100. At the same time, since water has a large specific heat capacity, it can absorb more heat, thereby effectively cooling the furnace wall 100, reducing energy consumption, and also reducing the footprint.

[0030] In some specific embodiments of this utility model, it may also have the following additional technical features: the turbulence column 220 is connected to the center of the turbulence unit.

[0031] In some specific embodiments of this utility model, it may also have the following additional technical features: the cross-sectional shape of the turbulence column 220 is formed by four arcs connected in sequence, and all four arcs are recessed toward the center of the turbulence column 220.

[0032] In some specific embodiments of this utility model, it may also have the following additional technical features: the line connecting two opposite vertices of the turbulence column 220 coincides with the line connecting the inlet and outlet of the turbulence unit, and the line connecting the other two opposite vertices of the turbulence column 220 is perpendicular to the line connecting the inlet and outlet of the turbulence unit.

[0033] In some specific embodiments of this utility model, it may also have the following additional technical features: the cross-sectional shape of the turbulence column 220 is composed of four symmetrical quarter-circle arcs. The radius of the arcs is 1m to 1.2m.

[0034] In some specific embodiments of this utility model, it may also have the following additional technical features: the turbulence unit includes an outer side wall 211, an inner side wall 212, a narrowing inlet 213, and a narrowing outlet 214. The outer side wall 211 and the inner side wall 212 are arranged opposite to each other, the inner side wall 212 abuts against the furnace wall 100, and the narrowing inlet 213 and the narrowing outlet 214 are respectively connected to the same end of the outer side wall 211 and the inner side wall 212. Adjacent narrowing inlets 213 and narrowing outlets 214 form a connection. Specifically, the length of the turbulence unit is 2m to 3m, and the width of the connection is 1m to 1.2m.

[0035] In some specific embodiments of this utility model, it may also have the following additional technical features: the narrowed inlet 213 and the narrowed outlet 214 are respectively 105°-120° with the outer side wall 211 and the inner side wall 212.

[0036] With the aforementioned design of the turbulence column 220 and turbulence unit, when the water flows into the turbulence unit from the narrowing inlet 213, the water flow undergoes a sudden expansion and pressure drop. At the same time, the presence of the turbulence column 220 causes the water flow to split. During the splitting process, the water flow is impacted, swirled, and turned sharply due to the influence of the arc of the turbulence column 220. After passing through the turbulence column 220, the water flow undergoes a sharp turn and convergence, thus forming turbulence. The turbulence will better exchange heat with the furnace wall 100, thereby effectively reducing the temperature of the furnace wall 100 and extending the service life of the furnace wall 100.

[0037] refer to Figure 3 As shown, in order to further improve the heat exchange efficiency, some specific embodiments of this utility model may also have the following additional technical features: a heat exchange rod 215 is connected to the inner sidewall 212, and one end of the heat exchange rod 215 extends into the furnace wall 100. Specifically, the heat exchange rod 215 is made of a metal material with high thermal conductivity, and it can use metal materials commonly used in the prior art, which are not limited here.

[0038] In some specific embodiments of this utility model, it may also have the following additional technical features: a shell 300 is mounted on the water-cooled pool, and a support 310 is connected inside the shell 300. A porous material layer 320 and multiple spray heads 330 are arranged sequentially from bottom to top on the support 310. The multiple spray heads 330 are all connected to the water storage pool through a water pump (not shown in the figure). When the water temperature in the water-cooled pool is high, the water in the water-cooled pool evaporates and dissipates to form steam. The steam rises and passes through the porous material layer 320. At this time, water or water mist is sprayed out from the spray heads 330. The water mist contacts the steam for heat exchange. When the temperature of the steam drops to the dew point, it re-condenses into water. The presence of the porous material layer 320 can slow down the rising speed of the steam. On the other hand, the water or water mist sprayed from the spray heads 330 will fall and adhere to the porous material layer 320. The porous material layer 320 can increase the contact area between the water or water mist and the steam, thereby achieving better heat exchange and thus achieving better energy saving and consumption reduction.

[0039] In some specific embodiments of this utility model, it may also have the following additional technical features: a vent 340 is provided on the top of the housing 300, and an exhaust fan 350 is connected to the top of the housing 300. By providing the vent 340 and the exhaust fan 350, the remaining water vapor carrying heat can escape from the vent 340, reducing the impact on the lower environment.

[0040] In some specific embodiments of this utility model, it may also have the following additional technical features: the porous material layer 320 is a hexagonal honeycomb structure made of plastic material.

[0041] It should be noted that circulating pumps and water pumps are both commonly used technologies in the present technology, and their specific structures and principles will not be elaborated here.

[0042] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
