Description

Technical Field

[0002] During industrial production processes such as glass production and waste incineration, a large amount of flue gas or waste gas is easily generated. Gas treatment mainly targets dust, toxic and harmful gases, nitrogen oxides, etc. in the waste gas, with the focus on reducing dioxin, heavy metal pollution, and PM2.5 fine dust. Existing technologies usually use semi-dry and dry methods for flue gas treatment to eliminate acidic dust, nitrogen oxides NOx, etc. generated in the gas, and reduce dioxin, heavy metal pollution, and PM2.5 fine dust. In the existing technology, the treatment of flue gas is completed through three main systems: a spray reaction tower, a primary and a secondary bag reactor. This process flow is complex, the project investment is large, and the speed of gas treatment by this method is slow. Also, dust removal facilities are set up, which reduces the efficiency of gas treatment. At the same time, in the process before entering the filter layer during gas treatment, there is no process for removing moisture in the gas, shortening the maintenance cycle of the equipment. Summary of the Utility Model

[0027] All terms used in this disclosure have the same meanings as those understood by those of ordinary skill in the art to which this disclosure pertains, unless otherwise specifically defined. It should also be understood that terms defined in a general dictionary, for example, should be interpreted as having meanings consistent with their meanings in the context of the relevant art, and should not be interpreted in an idealized or overly formal sense, unless specifically defined as such here.

[0028] Technologies, methods and devices known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods and devices should be regarded as part of the specification.

[0029] See Figure 1 、 Figure 2 and Figure 3 , on the one hand, this disclosure provides a gas purification device, including a housing, the housing is provided with an air inlet and an air outlet, the air inlet is connected to a gas generating device, and a dust removal unit 2, a uniform distribution unit 6, a dehumidification unit 3 and a filtration unit 9 are sequentially arranged in the housing in the direction from the air inlet to the air outlet.

[0030] It should be noted that in this embodiment, the flue gas in the glass production process is taken as an example. The flue gas passes through the dust removal unit 2, and the particulate matter therein is removed, and then enters the uniform distribution unit 6. The particulate matter includes dust and other solid particulate matters. Therefore, the efficiency of the uniform distribution unit 6 in removing particulate matter and acidic flue gas in the flue gas can be improved, and sulfur dioxide can be removed as soon as possible to form salt substances that can be captured and precipitated. After that, the flue gas enters the dehumidification unit 3 to remove the particulate matter generated during the flue gas treatment process and the remaining particulate matter and remove the moisture in the flue gas. Finally, it enters the filtration unit 9 to remove the organic pollutants and part of the heavy metals in the flue gas and then be discharged. Therefore, it can not only improve the treatment efficiency of the flue gas, but also extend the overhaul cycle of the equipment.

[0031] In some embodiments, a selective non-catalytic reduction device 1 is installed on the connecting pipeline between the air inlet and the gas generating device. Selective Non-Catalytic Reduction (SNCR) is a technology used to reduce nitrogen oxide emissions in flue gas. Compared with Selective Catalytic Reduction (SCR), SNCR does not require a catalyst, but realizes reduction by directly injecting a reducing agent into the high-temperature flue gas. Commonly used reducing agents such as ammonia water, urea or hydrazine hydrate, etc. The reducing agent is directly injected into the flue gas through a nozzle. The selection of the injection point is very important, generally located in a certain temperature range at the furnace outlet or in the flue, usually between 850°C and 1000°C. The effect of SNCR depends to a large extent on the flue gas temperature. If the temperature is too high or too low, the reduction efficiency of sulfides will decrease. At the same time, if too much reducing agent is injected, ammonia slip will occur, that is, the unreacted ammonia will enter the dust removal unit 2, the uniform distribution unit 6, the dehumidification unit 3 and the filtration unit 9 with the flue gas, preventing secondary pollution.

[0032] In some embodiments, an exhaust component 14 is connected to the air outlet. An exhaust power component 13 is provided on the connecting pipeline between the air outlet and the exhaust component 14. The exhaust power component 13 adjusts the rotation speed or air volume according to actual needs, so as to flexibly respond to the exhaust requirements under different working conditions, ensure that the gas can be smoothly transmitted from the air outlet to the exhaust component 14, and ensure the stable operation of the equipment. At the same time, when the internal pressure of the equipment is too high, the exhaust power component 13 can help quickly reduce the pressure and avoid dangerous situations such as backfire.

[0033] Among them, the exhaust power component 13 is a draft fan or other industrial fans, and the exhaust component 14 is a chimney or other suitable devices.

[0034] In some embodiments, the dust removal unit 2 includes a plurality of dust removal plates 15 arranged at intervals along the direction from the air inlet to the air outlet. The dust removal plate 15 includes a first plate member 15-1 and a second plate member 15-2. The first plate member 15-1 is serrated, and the second plate member 15-2 is located at the corner on the same side of the serrations of the first plate member 15-1. The first plate member 15-1 and the second plate member 15-2 respectively include a screen plate and filter cotton located inside the screen plate. The dust removal plates 15 are arranged in sequence according to the direction from the air inlet to the air outlet to filter the particulate matter in the flue gas step by step, ensuring that the flue gas is cleaner after being filtered through multiple stages. There is a certain distance between the dust removal plates 15, and such an arrangement ensures the smooth passage of gas and also provides sufficient space for the settlement of particulate matter.

[0035] It should be noted that the first plate member 15-1 is designed to be serrated. The serrated design increases the contact area between the first plate member 15-1 and the gas, which helps to capture particulate matter more effectively. The second plate member 15-2 is arranged at the corner on the same side of the first plate member 15-1 to guide the gas path, so that the gas continues to move along the second plate member 15-2 after passing through the first plate member 15-1, increasing the contact between the gas and the dust removal plate 15. The second plate member 15-2 and the first plate member 15-1 act together to improve the dust removal efficiency. The screen can block larger particulate matter and play a role in preliminary filtration, and the filter cotton further captures smaller particulate matter, especially fine dust.

[0036] In some embodiments, the uniform distribution unit 6 includes at least one swirl coupling mechanism arranged at intervals along the direction from the air inlet to the air outlet. One end of the swirl coupling mechanism is connected to a treatment liquid recycling device 8, and the other end is connected to a spraying device 7 for spraying treatment liquid into the swirl coupling mechanism. The liquid outlet of the treatment liquid recycling device 8 is communicated with the liquid inlet of the spraying device 7. Through the rotational movement of the swirl coupling mechanism, the contact area between the flue gas and the treatment agent is increased, and the treatment efficiency is improved. The treatment liquid recycling device 8 enables the agent to be recycled, reducing the consumption of the agent and lowering the operating cost. The design of the spraying device 7 ensures the uniform spraying of the agent and improves the efficiency of the chemical reaction.

[0037] It should be noted that the main function of the swirl coupling mechanism is to introduce rotational motion into the gas, making the flue gas more evenly distributed when passing through this mechanism. Through rotational motion, the contact area and contact time between the flue gas and the treatment agent are increased, improving the treatment efficiency. The treatment liquid recycling device 8 usually includes a pump and a liquid storage tank. The treated agent is pumped out of the liquid storage tank by the pump and then sent back to the injection device 7 through the return pipe. The injection device 7 is responsible for injecting the treatment agent into the flue gas. The agent is evenly dispersed into the flue gas through the injection device 7 and undergoes a chemical reaction with the pollutants in the flue gas. The injection device 7 usually includes a nozzle, and the design of the nozzle can ensure that the agent is ejected in the form of fine droplets, increasing the contact area with the flue gas. The return pipe connects the treatment liquid recycling device 8 and the injection device 7 to form a closed circulation system. This can ensure that the agent is recycled in the system, saving costs and improving the treatment efficiency.

[0038] In some embodiments, each swirl coupling mechanism includes a cylinder 16 that fits against the inner wall of the housing, a shaft seat 16-1 located inside the cylinder 16, a plurality of blades 16-2, and a blade driving member. The shaft seat 16-1 extends along the direction from the air inlet to the air outlet. The blades 16-2 are located on the outer periphery of the shaft seat 16-1. The blade driving member drives the shaft seat 16-1 to rotate. The cylinder 16 is the main structure of the swirl coupling mechanism, used to accommodate and support the internal shaft seat 16-1 and blades 16-2. The shape of the cylinder 16 is usually cylindrical or a similar structure to facilitate the smooth passage of gas. The cylinder 16 is usually made of corrosion-resistant and high-temperature-resistant materials to adapt to the harsh environment of industrial flue gas treatment. The shaft seat 16-1 is used to install and fix the blades 16-2 and rotate it through a driving element. The shaft seat 16-1 is usually located inside the cylinder 16, and one or more are provided as needed. The blades 16-2 rotate under the action of the driving element, generating a rotating air flow, so that the particulate matter and pollutants in the flue gas are more likely to come into contact with the treatment agent. The number and shape of the blades 16-2 are designed according to actual needs, usually multiple blades are arranged in a spiral or radial pattern to generate an effective rotating air flow. The driving element is used to drive the blades 16-2 to rotate and can be a motor or other types of driving devices.

[0039] Regarding the operation of the swirl coupling mechanism, it should be noted that the flue gas enters the cylinder 16 through the inlet of the cylinder 16. The driving element is started, driving the blades 16-2 on the shaft seat 16-1 to rotate. The rotation of the blades 16-2 generates a strong rotating air flow, making the particulate matter and pollutants in the gas come into full contact with the treatment agent during the rotational motion. Due to the rotation of the blades 16-2, the gas forms a vortex motion inside the cylinder 16, increasing the contact time and contact area between the gas and the treatment agent and improving the efficiency of the chemical reaction. The treated gas is discharged through the outlet of the cylinder 16 and enters the subsequent treatment unit.

[0040] In some embodiments, the dehumidification unit 3 includes a particle layer and a dehumidification layer arranged in sequence along the direction from the air inlet to the air outlet. One end of the particle layer is connected to the particle feeding device 4, and the other end is connected to the particle recovery device 5. The discharge port of the particle recovery device 5 is communicated with the feed port of the particle feeding device 4. The particle layer is mainly used to capture and remove fine particulate matters in the flue gas and can absorb part of the moisture. Adsorbent materials such as clay-based adsorbents and cellulose-based materials can be filled therein; the dehumidification layer is mainly used to remove the moisture in the flue gas to ensure the dryness of the flue gas. Other hygroscopic agents such as silica gel and molecular sieve can be filled therein. The particle feeding device 4 is used to supply effective adsorbent materials to the particle layer of the dehumidification unit 3 to ensure the adsorption capacity of the adsorbent materials. The particle recovery device 5 is used to collect the adsorbent materials that have lost their adsorption capacity and regenerate them through treatment or directly recycle and utilize them. The reflux pipe is used to connect the particle recovery device 5 and the particle feeding device 4 to realize the cyclic use of the adsorbent materials.

[0041] Regarding the working process of the dehumidification unit, it should be noted that the adsorbent materials are transported to one end of the particle layer of the dehumidification unit 3 through the particle feeding device 4. After the flue gas enters the dehumidification unit 3, it first passes through the particle layer, where the particulate matters are captured by the adsorbent materials and part of the moisture is also adsorbed. Then the flue gas enters the dehumidification layer to further remove the moisture. As the flue gas continuously passes through the dehumidification unit 3, the adsorbent materials gradually move to the other end of the particle layer until they reach the particle recovery device 5. The adsorbent materials reaching the particle recovery device 5 are collected and their adsorption capacity is restored through regeneration treatment. The treated adsorbent materials are sent back to the particle feeding device 4 through the reflux pipe and put into use again. The adsorbent materials are continuously cycled in the dehumidification unit 3 to ensure the effective removal of particulate matters and moisture in the flue gas.

[0042] In some embodiments, the filtration unit 9 includes an activated carbon layer. One end of the activated carbon layer is connected to the activated carbon feeding device 10, and the other end is connected to the activated carbon recovery device 11. The discharge port of the activated carbon recovery device 11 is communicated with the feed port of the activated carbon feeding device 10. The activated carbon layer is mainly used to adsorb and remove organic pollutants, some heavy metals and other harmful gases in the flue gas. The activated carbon has a large specific surface area and a developed pore structure, which can efficiently adsorb these pollutants. The activated carbon feeding device 10 is used to provide fresh activated carbon to the filtration unit 9. The activated carbon recovery device 11 is used to collect the old activated carbon that has lost its adsorption capacity and perform regeneration treatment on it or directly recycle and utilize it. The reflux pipe is used to connect the activated carbon recovery device 11 and the activated carbon feeding device 10 to realize the cyclic use of the activated carbon.

[0043] Regarding the operation of the filtration unit, it should be noted that effective activated carbon is conveyed to one end of the activated carbon layer of the filtration unit 9 through the activated carbon feeding device 10. After the flue gas enters the filtration unit 9, it passes through the activated carbon layer, and the organic pollutants, heavy metals, and other harmful gases therein are adsorbed by the activated carbon. As the flue gas continuously passes through the filtration unit 9, the activated carbon adsorbed with pollutants gradually moves to the other end of the activated carbon layer until it reaches the activated carbon recovery device 11. The used activated carbon reaching the activated carbon recovery device 11 is collected and its adsorption capacity is restored through regeneration treatment. The regeneration methods usually include heating desorption, steam purging, chemical cleaning, etc. The treated activated carbon is sent back to the activated carbon feeding device 10 through the reflux pipe and put back into use. The activated carbon is continuously recycled in the filtration unit 9 to ensure the effective removal of harmful substances in the flue gas.

[0044] In some embodiments, a gas detector 12 is installed at the air inlet. The gas detector 12 is installed at the air inlet and is used to monitor the concentration of pollutants in the flue gas entering the system in real time. The gas detector 12 adopts various technologies, such as infrared spectroscopy analysis, ultraviolet spectroscopy analysis, electrochemical sensors, etc., to achieve precise measurement of different pollutants. The control system is responsible for receiving the data of the gas detector 12 and adjusting the working parameters of the injection device 7 according to these data. The injection device 7 is responsible for injecting the treatment agent into the flue gas and adapting to different treatment requirements by changing the form and flow rate of the injected agent. The injection device 7 has a multi-nozzle structure, and each nozzle can be independently controlled to achieve different injection modes. The injection device 7 can adjust the injection amount and injection form of the agent through a solenoid valve or other control devices.

[0045] To better understand the technical solutions of the present disclosure, the following is described in combination with relatively preferred technical features.

[0046] The present disclosure provides a gas purification device, which includes a housing. The housing is provided with an air inlet and an air outlet. The air inlet is connected to a gas generating device, and a selective non-catalytic reduction device 1 is installed on the connecting pipeline between the air inlet and the gas generating device. A gas detector 12 is installed at the air inlet. A dust removal unit 2, a uniform distribution unit 6, a dehumidification unit 3, and a filtration unit 9 are sequentially arranged in the housing from the air inlet to the air outlet direction. The dust removal unit 2 includes a plurality of dust removal plates 15 arranged at intervals in the direction from the air inlet to the air outlet. The dust removal plate 15 includes a first plate member 15-1 and a second plate member 15-2. The first plate member 15-1 is serrated, and the second plate member 15-2 is located at the corner on the same side of the serrations of the first plate member 15-1. The first plate member 15-1 and the second plate member 15-2 respectively include a screen plate and filter cotton located inside the screen plate. The uniform distribution unit 6 includes at least one swirl coupling mechanism arranged at intervals in the direction from the air inlet to the air outlet. One end of the swirl coupling mechanism is connected to a treatment liquid recycling device 8, and the other end is connected to a spraying device 7 for spraying treatment liquid into the swirl coupling mechanism. The liquid outlet of the treatment liquid recycling device 8 is communicated with the liquid inlet of the spraying device 7. Each swirl coupling mechanism includes a cylinder 16 attached to the inner wall of the housing, a shaft seat 16-1 located inside the cylinder 16, a plurality of blades 16-2, and a blade driving member. The shaft seat 16-1 extends in the direction from the air inlet to the air outlet, the blades 16-2 are located on the outer periphery of the shaft seat 16-1, and the blade driving member drives the shaft seat 16-1 to rotate. The dehumidification unit 3 includes a particle layer and a dehumidification layer arranged in sequence in the direction from the air inlet to the air outlet. One end of the particle layer is connected to a particle feeding device 4, and the other end is connected to a particle recovery device 5. The discharge port of the particle recovery device 5 is communicated with the feed port of the particle feeding device 4. The filtration unit 9 includes an activated carbon layer. One end of the activated carbon layer is connected to an activated carbon feeding device 10, and the other end is connected to an activated carbon recovery device 11. The discharge port of the activated carbon recovery device 11 is communicated with the feed port of the activated carbon feeding device 10. The air outlet is connected to an exhaust member 14, and an exhaust power member 13 is arranged on the connecting pipeline between the air outlet and the exhaust member 14.

[0047] The above solution has the following advantages. First, the flue gas enters the selective catalytic reduction (SCR) device. In this device, ammonia water is sprayed into the flue gas as a reducing agent and comes into contact with nitrogen oxides in the flue gas. Under the action of the catalyst, the nitrogen oxides are reduced to nitrogen and water. This process effectively reduces the concentration of nitrogen oxides in the waste gas. The waste gas after SCR treatment then enters the dust removal unit. The dust removal plates 15 are arranged in sequence from the air inlet to the air outlet, filtering the particulate matter in the flue gas step by step to ensure that the flue gas is cleaner after multi-stage filtration. There is a certain distance between each dust removal plate 15. Such an arrangement ensures the smooth passage of the gas and also provides enough space for the settlement of particulate matter. The second plate member 15-2 is arranged at the same-side corner of the first plate member 15-1 to guide the gas path, so that the gas continues to move forward along the second plate member 15-2 after passing through the first plate member 15-1. The flue gas enters the cylinder 16 through the inlet of the cylinder 16. The driving element is started to drive the blades 16-2 on the shaft seat 16-1 to rotate. The rotation of the blades 16-2 generates a strong rotating airflow, enabling the particulate matter and pollutants in the gas to come into full contact with the treatment agent during the rotational movement. Due to the rotation of the blades 16-2, the gas forms a vortex motion in the cylinder 16, increasing the contact time and contact area between the gas and the treatment agent, improving the efficiency of the chemical reaction, and effectively removing the acidic gas therein. Then it is discharged through the outlet of the cylinder 16 and enters the subsequent dehumidification unit. The adsorption material is transported to one end of the particle layer of the dehumidification unit 3 through the particle feeding device 4. After the flue gas enters the dehumidification unit 3, it first passes through the particle layer, where the particulate matter is captured by the adsorption material and part of the moisture is also adsorbed. Then the flue gas enters the dehumidification layer to further remove moisture. As the flue gas continuously passes through the dehumidification unit 3, the adsorption material gradually moves to the other end of the particle layer until it reaches the particle recovery device 5. The adsorption material reaching the particle recovery device 5 is collected and its adsorption capacity is restored through regeneration treatment. The treated adsorption material is sent back to the particle feeding device 4 through the return pipe and put back into use. The adsorption material is continuously recycled in the dehumidification unit 3 to ensure that the particulate matter and moisture in the flue gas are effectively removed and then enter the activated carbon layer. After the flue gas enters the filtration unit 9, it passes through the activated carbon layer, where the organic pollutants, heavy metals and other harmful gases are adsorbed by the activated carbon. As the flue gas continuously passes through the filtration unit 9, the activated carbon adsorbed with pollutants gradually moves to the other end of the activated carbon layer until it reaches the activated carbon recovery device 11. The used activated carbon reaching the activated carbon recovery device 11 is collected and its adsorption capacity is restored through regeneration treatment. The regeneration methods usually include heating desorption, steam purging, chemical cleaning, etc. The treated activated carbon is sent back to the activated carbon feeding device 10 through the return pipe and put back into use. The activated carbon is continuously recycled in the filtration unit 9. The treated gas is discharged through the exhaust part 14, which can improve the gas treatment efficiency and at the same time extend the maintenance cycle of the equipment.

[0048] The present disclosure also provides a glass production system, including the gas purification device of any one of the above.
