Description

TECHNICAL FIELD

[0001] The utility model relates to electronic glass kiln auxiliary equipment technical field, concretely relates to a kind of electronic glass kiln flue gas cooling device. BACKGROUND

[0002] Glass raw materials are melted into glass liquid under the action of pool furnace high temperature, and a large amount of polluting gas will be generated under high-temperature baking. In the process of glass firing, a dissolving agent is added to the glass composition to reduce the glass manufacturing temperature, and some additives are also added to improve the properties of the glass. Therefore, the composition of the glass raw materials in the pool furnace is relatively complex. Nitrogen oxides generated by the decomposition of multiple raw materials under high temperature are discharged with the gas. NO2 begins to decompose into NO and O2 when the temperature is higher than 150 ℃, and it is completely decomposed at 650 ℃. The firing temperature of liquid crystal glass is 1500-1650 ℃, and the flue gas temperature is relatively high. If it is directly discharged, it will cause damage to the flue gas treatment equipment and shorten the service life of the exhaust pipe. SUMMARY

[0003] The purpose of the utility model is to provide a kind of electronic glass kiln flue gas cooling device to overcome the problems in the prior art. The utility model passes through the first air supplement pipe and the second air supplement pipe to pass cooling air into the second mixing cavity. After preheating, the cooling air is discharged into the first mixing cavity. The preheated cooling air mixes with high-temperature flue gas in the second mixing cavity. It can cool the kiln high-temperature flue gas, significantly reduce the temperature of the flue gas, reduce the erosion of the flue material by high temperature, reduce the temperature load of the rear section of the steel flue, and reduce the cost of the steel flue material.

[0004] To achieve the above-mentioned purpose, the utility model adopts the following technical solutions:

[0005] A kind of electronic glass kiln flue gas cooling device, comprising a cavity device and a wind pipe device;The cavity device comprises a first mixing cavity, a plurality of air inlet holes are arranged on the two sides of the first mixing cavity, a second mixing cavity is installed on the inner side of the first mixing cavity, the second mixing cavity comprises an outer end face, the outer end face is installed with an inner end face through a connecting cavity, and a plurality of air outlet holes are arranged on the inner end face;The wind pipe device comprises a first air supplement pipe, a second air supplement pipe and an exhaust pipe, the first air supplement pipe and the second air supplement pipe are connected with the plurality of air inlet holes on the two sides of the first mixing cavity respectively, and the exhaust pipe is installed on the top of the first mixing cavity;

[0006] Further, the air inlet holes are symmetrically arranged on the two sides of the first mixing cavity;

[0007] Further, the plurality of air outlet holes are arranged around the connecting cavity;

[0008] Further, the first air supplement pipe, the second air supplement pipe and the exhaust pipe are in the shape of a horn;

[0009] Further, the first air supplementing pipe comprises a first air inlet, and the first air inlet is connected with a first air outlet through a first air inlet pipeline;

[0014] Further, the smoke outlet is connected with the top of the first mixing cavity.

[0015] The above technical scheme has the following advantages or beneficial effects:

[0016] The electronic glass kiln flue gas cooling device provided by the utility model has the advantages that the first mixing cavity and the second mixing cavity are arranged, and the air inlets and the air outlets are arranged around the first mixing cavity and the second mixing cavity, so that the high-temperature flue gas can be effectively mixed and cooled; the outer end surface of the second mixing cavity is connected with the inner end surface through the connecting cavity, which helps to form an annular air duct, can more fully preheat and improve the heat exchange efficiency, and thus can more effectively reduce the temperature of the flue gas; the cold air enters the air inlets through the first air supplementing pipe and the second air supplementing pipe, is preliminarily mixed and preheated in the second mixing cavity, then enters the first mixing cavity through the air outlets for further mixing, and is discharged through the smoke discharging pipe, so that the temperature of the flue gas can be significantly reduced and the cooling efficiency can be improved; meanwhile, the gas that does not pass through the preheating process is directly used to rapidly cool the flue gas, and a large amount of glass raw material dust exists, which can cause coking at the gas intersection and block the flue gas passage, and thus can affect the production furnace pressure fluctuation; the double-layer mixing design of the cavity device not only improves the cooling efficiency, but also optimizes the structural layout; the cooling air is preheated before entering the first mixing cavity, so that the energy consumption required in the subsequent cooling process is reduced compared with the case that the cooling air is directly introduced; meanwhile, the temperature of the flue gas is effectively reduced, so that the temperature load of the subsequent steel flue is reduced, and thus a steel flue material with a lower cost can be selected, and the equipment investment and operation cost can be reduced; the arrangement of the plurality of air inlets and air outlets can ensure that the cold air and the high-temperature flue gas are fully contacted and mixed in each direction, so that the phenomenon of local overheating or overcooling is avoided, the uniformity of the cooling effect is ensured, the subsequent equipment can be protected, and the product quality can be maintained; the device has a simple structure, the connection between the components is clear, and the device is convenient to operate and maintain; when it is necessary to clean or replace the components, the device can be conveniently disassembled and assembled, so that the maintenance cost and time are reduced.

[0017] Further, the air inlet holes are symmetrically arranged on both sides of the first mixing cavity, which helps to realize uniform distribution of the flue gas when entering the device, thereby enhancing the mixing effect of the flue gas in the first mixing cavity.

[0018] Further, the horn divergent design can gradually expand the cross-sectional area of the two air supplement pipes and the exhaust pipe during airflow transmission, thereby slowing down the airflow speed, making the air volume distribution more uniform, helping to ensure that the cooling air can uniformly enter the two mixing cavities and fully mix with the high-temperature flue gas, and improving the cooling effect.
