Description

TECHNICAL FIELD

[0001] The utility model relates to glass product manufacturing technical field, specifically, a kind of horse hoof flame glass kiln directional oxygen-increasing mixed combustion integrated system. BACKGROUND

[0002] At present stage, the application of oxygen-enriched combustion combustion-supporting technology in domestic is delayed to be popularized in large area in industrial manufacturing field.The reason is that the existing oxygen-enriched combustion combustion-supporting application technology is the technical route of whole oxygen-increasing combustion-supporting to industrial kiln, although whole oxygen-increasing combustion-supporting technology can improve combustion efficiency, achieve certain energy-saving effect, but whole oxygen-increasing combustion-supporting technology has following several shortcomings problems:

[0003] I. the investment cost of oxygen production equipment of whole oxygen-increasing is huge;

[0004] II. the oxygen-adding mode of whole oxygen-increasing combustion-supporting is added from primary air duct and secondary air duct, so a large amount of oxygen is needed, the energy consumption of oxygen production equipment of whole oxygen-increasing is superhigh, investment return cycle is long, the energy saved by whole oxygen-increasing offsets the electric energy consumption of self equipment, and forms a cycle of energy-saving but not money-saving;

[0005] III. for horse hoof flame glass kiln in glass manufacturing field, whole oxygen-increasing combustion-supporting mode makes the hearth temperature of horse hoof flame glass kiln too high, shortens the service life of horse hoof flame glass kiln, and the traditional horse hoof flame glass kiln has the problem of insufficient combustion, the utilization rate of fuel is relatively low, and a large amount of harmful gas is also generated.

[0006] The above shortcomings problems become the technical bottleneck that needs to be broken through urgently. CONTENT OF UTILITY MODEL

[0007] In view of this, the utility model aims at designing a kind of horse hoof flame glass kiln directional oxygen-increasing mixed combustion integrated system, adopts directional oxygen-increasing mixed combustion technology, adds oxygen-increasing oxygen from the two sides of breast wall of horse hoof flame glass kiln directly, and occurs combustion reaction with hearth flame, solves the problems of insufficient combustion and unstable furnace condition of traditional horse hoof flame glass kiln;It can be designed and customized according to different kiln to solve the technical problems of high investment cost and superhigh equipment energy consumption of existing whole oxygen-increasing equipment, improve the combustion efficiency in horse hoof flame glass kiln smelting process, save energy consumption, and reduce carbon emission.

[0008] The utility model provides a kind of horseshoe flame glass kiln directional oxygen-increasing mixed combustion integrated system, comprising: kiln body, spray gun, the spray gun is set in the two sides of breast wall of the kiln body, the nozzle of the spray gun is towards the hearth inside of kiln body;The spray gun is connected with fan mixing system, oxygen generation system connected in sequence;The fan mixing system includes: high-temperature high-pressure fan, air supply pipeline;The high-temperature high-pressure fan is connected with the oxygen generation system, and the high-temperature high-pressure fan is connected to the spray gun via the air supply pipeline.All spray gun realizes full-automatic timing telescoping, reversing oxygen-increasing function.

[0009] Specifically, oxygen output by oxygen generation system is compressed by high-temperature high-pressure fan, and then is delivered to spray gun on the two sides of breast wall by air supply pipeline for combustion support;

[0010] High-temperature high-pressure fan is the core equipment of fan mixing system, which can generate sufficient air volume and air pressure.Air supply pipeline mainly plays the role of conveying directional oxygen-increasing oxygen, and spray gun sprays directional oxygen-increasing oxygen to molten bath in the inside of kiln body for combustion support, and controls air flow in molten bath to promote temperature balance in molten bath.Directive oxygen-increasing combustion support mode avoids the problems of insufficient combustion and unstable furnace condition of horseshoe flame glass kiln, and prolongs the service life of horseshoe flame glass kiln.

[0011] Compared with traditional combustion technology, the directional oxygen-increasing combustion technology of the utility model can improve energy efficiency by about 10% to 30% when applied to horseshoe flame glass kiln.Glass production requires high temperature, and needs uniform and stable high-temperature environment.Directive oxygen-increasing mixed combustion technology can improve flame temperature and heat transfer efficiency, which is helpful for melting and refining of glass raw materials, and improves glass quality and production efficiency.Because combustion is more sufficient, with the increase of temperature, combustion-supporting air volume and natural gas consumption can be significantly reduced.Excessive air is greatly reduced, so that tail gas emission is also significantly reduced, achieving real energy saving and emission reduction.

[0012] Economic benefit analysis: taking a horseshoe flame glass kiln with daily natural gas consumption of 28000 cubic meters as an example, and taking the lowest standard 10% energy saving rate, 2800 cubic meters of natural gas is saved every day, according to the current average price of natural gas in China, 3.6 yuan per cubic meter, more than 10000 yuan is saved every day, excluding electricity cost, more than 3000,000 yuan of income can be created for enterprises every year, and the equipment investment recovery period is not more than one year.

[0013] Further, the nozzles of the spray gun are in parallel in multiple groups, the nozzles in multiple parallel groups are uniformly arranged on the breast wall of the horseshoe flame glass kiln, and the nozzles are arranged in the same number on the two sides of the breast wall of the horseshoe flame glass kiln.

[0014] Specifically, the multiple groups of nozzles can make the spraying range more comprehensive, and the uniform arrangement of the multiple groups of nozzles can make the spraying range more balanced, so that the fuel center of the fuel is maximally sprayed into, and the fuel is fully and completely combusted, and the effect of energy saving and emission reduction is further optimized.

[0015] Preferably, the spray gun has four groups of nozzles on each side of the breast wall of the horse flame glass kiln.

[0016] Preferably, the nozzles of the spray gun adopt a special specification, and the inner diameter of the spraying port is φ65mm.

[0017] Further, the discharge port of the kiln body is connected with a high-temperature filter, the high-temperature filter is connected to the high-temperature high-pressure fan, and the tail gas of the discharge port passes through the high-temperature filter and returns to the kiln body from the high-temperature high-pressure fan.

[0018] After the tail gas discharged by the horse flame glass kiln is filtered by the high-temperature filter, the tail gas is circulated by the high-temperature high-pressure fan, which not only reduces the hearth temperature of the kiln body, but also significantly reduces the tail gas emission of the horse flame glass kiln, and further improves energy saving and emission reduction.

[0019] Further, an oxygen-enriched pressure stabilizing tank is arranged on the air supply pipeline between the high-temperature high-pressure fan and the spray gun, and the oxygen-enriched pressure stabilizing tank is signal connected with the high-temperature high-pressure fan.

[0020] The function of the oxygen-enriched pressure stabilizing tank is to maintain the pressure in the air supply pipeline. When the pressure in the air supply pipeline decreases to a certain value, the high-temperature high-pressure fan will automatically start to increase the pressure in the air supply pipeline. When the pressure in the air supply pipeline reaches a specified value, the high-temperature high-pressure fan will stop, and the pressure in the air supply pipeline will be maintained by the oxygen-enriched pressure stabilizing tank, so that the oxygen-enriched and oxygen-increasing combustion process can continue smoothly, and the continuity and stability of the oxygen-enriched and oxygen-increasing combustion are ensured.

[0021] Further, the oxygen production system comprises an oxygen production device and an oxygen-enriched buffer tank, the oxygen production device is connected with the oxygen-enriched buffer tank, the oxygen-enriched buffer tank comprises a pressure container, a pressure sensor and a safety pressure relief valve, the pressure sensor is arranged in the pressure container, and the safety pressure relief valve is arranged on the side wall or the bottom of the pressure container.

[0022] The oxygen-enriched buffer tank is a component specially designed for the storage and balance of oxygen in the oxygen production system. The oxygen-enriched buffer tank mainly plays the following roles:

[0023] (1) Ensure stable oxygen supply: The oxygen-enriched buffer tank stores oxygen, balances the difference between the oxygen flow generated by the oxygen production device and the actual oxygen flow used, ensures continuous and stable oxygen supply, avoids unnecessary oxygen waste, and improves the utilization rate of oxygen.

[0024] (2) Balance the pressure of oxygen: The pressure of oxygen generated by the oxygen generating equipment will decrease as the oxygen is consumed. Without the intervention of the oxygen enrichment buffer tank, it will lead to unstable oxygen flow and cannot meet the actual demand. The oxygen enrichment buffer tank can maintain the stability of the oxygen pressure by storing oxygen and adjusting the pressure. When the oxygen pressure is lower than the set value, the oxygen in the oxygen enrichment buffer tank will be released to maintain stable oxygen supply.

[0025] (3) Ensure the safety of the oxygen generating equipment: The oxygen enrichment buffer tank is equipped with safety devices such as safety relief valve. Once the oxygen pressure in the buffer tank is too high or leaks, the safety relief valve will automatically start to release the pressure, ensuring the safe operation of the oxygen generating equipment. Therefore, the setting of the oxygen enrichment buffer tank can effectively avoid accidents and ensure personal safety and equipment integrity.

[0026] For vertical pressure vessels, setting safety relief valves at the bottom can better maintain and replace them.

[0027] Further, the oxygen generating system further comprises a buffer gas tank arranged at the front end of the oxygen generating device, and the buffer gas tank is connected to the oxygen generating device.

[0028] The buffer gas tank is used to adjust the gas flow, and the gas flow is adjusted and controlled by the pressure of the gas in the buffer gas tank. When the gas flow fluctuates in the buffer gas tank, the buffer gas tank will automatically adjust the gas pressure to maintain the stability of the gas flow, thereby achieving precise control of the gas flow, so that the downstream equipment can receive gas with stable pressure and flow. To ensure the stability and reliability of the oxygen generating equipment, stable, smooth and undulating gas needs to be input. The buffer gas tank can make the gas output more stable, thereby improving the stability of the oxygen generating equipment.

[0029] Further, the oxygen generating system further comprises an activated carbon filter arranged at the front end of the buffer gas tank, and the activated carbon filter is connected to the buffer gas tank.

[0030] The activated carbon filter can selectively adsorb impurities such as nitrogen, carbon dioxide and water in the air, and desorb the molecular sieve under vacuum conditions, thereby recycling oxygen with high purity (90-94%).

[0031] When the activated carbon filter adsorbs to a certain extent, the activated carbon adsorbent in it will reach a saturated state. At this time, the activated carbon adsorbent is vacuumized (in the opposite direction of adsorption), and the vacuum degree is 0.65-0.75 barg. The adsorbed water, carbon dioxide, nitrogen and a small amount of other gas components are extracted and discharged to the atmosphere, and the activated carbon adsorbent is regenerated.

[0032] Preferably, the front end of the activated carbon filter is also connected with a precision filter. The precision filter is sealed, has large flow, and accurate filtering accuracy, so as to meet the requirements of the output gas quality.

[0033] Further, the oxygen production system further comprises a refrigeration dryer arranged at the front end of the activated carbon filter, and the refrigeration dryer is connected with the activated carbon filter.

[0034] The refrigeration dryer is mainly used for reducing the humidity of compressed air, removing moisture, and reducing the dew point to below 10°C, and the water content is less than 9g / m³.

[0035] Further, the oxygen production system further comprises a mountain double-stage air compressor arranged at the front end of the refrigeration dryer, and the mountain double-stage air compressor is connected with the refrigeration dryer.

[0036] The mountain double-stage air compressor realizes the compression of air through two-stage compression process. In the first stage, the air is preliminarily compressed by the first-stage screw rod; in the second stage, the air is compressed again by the second-stage screw rod. This double-stage compression design makes the compression process more efficient, while reducing energy consumption and heat generation.

[0037] Further, the oxygen production system further comprises VPSA and PSA pressure swing adsorption oxygen production equipment. Preferably, there are also cryogenic oxygen production, membrane oxygen production, and pipeline oxygen.

[0038] Further, the horse-shoe flame glass furnace directional oxygen-increasing mixed combustion integrated system further comprises a control system, which is signal-connected with the oxygen production system and the fan mixing system respectively; the control system comprises a temperature control system, a gas control system, and an electrical control system.

[0039] Preferably, the horse-shoe flame glass furnace directional oxygen-increasing mixed combustion integrated system adopts PLC intelligent control throughout (without personnel on duty).

[0040] The temperature control system measures the temperature in the glass furnace tank through a sensor, adjusts the air supply and gas amount according to the set value, so as to achieve the purpose of temperature control.

[0041] The gas control system controls the mixing ratio and supply amount of gas, oxygen-increasing oxygen, and air, so as to ensure the completeness of combustion and adjust the oxygen concentration of the tank.

[0042] The electrical control system controls the operation process of the horse-shoe flame glass furnace, such as starting, stopping, program running, and fault alarm, etc.

[0043] The oxygen adding mode of the directional oxygen increasing mixed combustion technology is directional adding from the two sides of the breast wall of the horse-shoe flame glass kiln, and directly combusting with the flame of the hearth.

[0044] Compared with the traditional combustion technology, the energy saving efficiency of the horse-shoe flame glass kiln adopting the directional oxygen increasing combustion technology can be generally increased by about 10% to 30%.

[0045] Compared with the prior art, the horse-shoe flame glass kiln directional oxygen increasing mixed combustion integrated system has the advantages that:
