If these exhaust gases are discharged directly, they will cause serious pollution, but if they are completely cooled and purified, a large amount of heat energy will be lost. How to effectively remove harmful substances while maximizing the recovery of heat energy and combustible components in the exhaust gas? The existing wet dust removal system has problems such as high energy consumption and large water resource consumption. In addition, the wastewater after washing contains a large amount of pollutants, and how to achieve efficient treatment and recycling of wastewater is also a major problem. On the premise of ensuring the dust removal effect, how to optimize the system design, improve energy utilization efficiency, reduce operating costs, and achieve coordinated management of waste gas and wastewater are technical problems that need to be solved in the coking industry.

[0008] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0009] like Figure 1-3 In this embodiment, a method for treating VOCs and dust in the exhaust gas from the pyrolysis device may specifically include: S101, obtaining high-temperature coke exhaust gas with a temperature in the range of 800-1000° C., wherein the exhaust gas contains combustible gas, ammonia, hydrogen sulfide and particulate dust.

[0010] According to the technical parameters and on-site conditions of the coke silo and coke belt conveyor, the appropriate type of intelligent wet dust removal device is calculated and selected. A double-seal isolation guide trough is used to improve the sealing of the guide trough and prevent the spread of waste gas and dust. The guide trough is made of 304 stainless steel, which is corrosion-resistant and wear-resistant, and has a longer service life. The curved coal drop pipe structure is designed to allow high-temperature materials to slide in the coal drop pipe in an orderly manner, reduce the material outlet speed, reduce the impact of materials on the belt and the guide trough, and prevent the gas from falling and impacting to form diffusion. Through the pre-cooling and pre-dust removal atomization spray of the intelligent wet dust removal device, the high-temperature coke exhaust gas of 800-1000℃ and the combustible gas, ammonia, hydrogen sulfide, particulate dust, etc. in it are initially purified. The gas and trace dust after primary purification enter the secondary mixed washing part of the intelligent wet dust removal device, and are fully combined with water, so that ammonia, hydrogen sulfide, particulate dust, etc. are fully fused with water. The gas after mixed washing enters the dehydration part, and after dehydration and separation, purified air and combustible gas are obtained. The purified air and combustible gas are recycled and connected to the blast system of the coking pyrolysis unit for combustion and coking. The separated mud and water flow back to the sump sedimentation tank through the sewage pipe, and are recycled after sedimentation and filtration, and the sludge is discharged to the sewage treatment system. By setting up multiple rubber dust suppression devices, several unit negative pressure spaces are formed inside the guide trough, which are used in conjunction with the intelligent wet dust removal scrubber to further improve the dust removal effect.

[0011] Exemplary.

[0012] S102, conveying the cooled exhaust gas to a pre-dust removal atomizing spray device, atomizing water into droplets with a diameter of 20-50 microns through a high-pressure nozzle, which fully contacts the exhaust gas, removes most of the dust in the exhaust gas, and obtains exhaust gas after preliminary dust removal.

[0013] According to the temperature and humidity of the exhaust gas, a cooling device is used to cool the exhaust gas to reduce the exhaust gas temperature to a preset range. The cooled exhaust gas is transported to the pre-dust removal atomization spray device, and water is atomized into droplets with a diameter of 20-50 microns through a high-pressure nozzle. The atomized droplets are controlled to fully contact with the exhaust gas, and most of the dust in the exhaust gas is removed by the collision and adsorption of the droplets and dust particles. The exhaust gas after the pre-dust removal atomization spray treatment is collected to obtain the exhaust gas after preliminary dust removal. The exhaust gas after preliminary dust removal is introduced into the secondary mixing and washing part of the intelligent wet dust removal device, and forms a gas-liquid two-phase high-speed rotating flow with the high-speed rotating impeller. The high-speed rotation of the mixing impeller fully mixes the exhaust gas with water, and generates strong turbulence and shearing effects, further removing fine dust and harmful gases in the exhaust gas. After the mixed washing treatment, the exhaust gas and the washing liquid are introduced into the dehydration separation part together, and the gas-liquid separation is performed by cyclone separation and demister and other devices. Separate the purified waste gas, recycle the combustible gas, and connect it to the blast system of the coking pyrolysis device for combustion and coking. Collect the separated washing liquid and discharge it into the sump sedimentation tank for sedimentation and filtration. The treated water is reused in the intelligent wet dust removal system to achieve water recycling.

[0014] For example, according to the temperature and humidity of the exhaust gas, a cooling device is used to cool the exhaust gas, such as using a heat exchanger to reduce the exhaust gas temperature from 200°C to about 50°C, and controlling the humidity below 70%. The cooled exhaust gas is atomized into water droplets with a diameter of 20-50 microns through a high-pressure nozzle, the nozzle pressure is controlled at 10-20MPa, and the volume ratio of the atomized droplets to the exhaust gas is controlled at 1:500-1:1000. The collision and adsorption of the droplets and dust particles are used to remove more than 80% of the coarse dust. The exhaust gas after preliminary dust removal is introduced into the secondary mixing and washing part, and forms a gas-liquid two-phase high-speed rotating flow with the mixing impeller with a rotation speed of 3000-6000rpm. Under a pressure difference of 500-1000Pa, the exhaust gas and water are fully mixed, generating strong turbulence and shearing effects, and the removal rate of fine dust is more than 90%, and the removal rate of harmful gases such as SO2 and NOx is more than 70%. The washed waste gas and washing liquid are introduced into the cyclone separator together, and the gas-liquid separation is achieved under the pressure difference of 4000-6000Pa, and then the entrained water droplets are removed by the demister, and the separation efficiency reaches more than 99%. The purified combustible gas is recycled and connected to the blast system of the coking pyrolysis device above 1200℃ for combustion and coking. The separated washing liquid is discharged into the sump sedimentation tank of more than 1000m³, and reused after flocculation, sedimentation, filtration and other treatments, and the recycling rate of water reaches more than 90%.

[0015] S103, conveying the exhaust gas after preliminary dust removal to a mixing impeller device, using a high-speed rotating mixing impeller with a diameter of 1-1.5 meters and a rotation speed of 1500-2000 rpm to fully mix and wash the exhaust gas with water to obtain a washed gas-liquid mixture.

[0016] According to the technical parameters of the coke bin and the coke belt conveyor and the on-site conditions, a suitable type of intelligent wet dust removal device is selected, and the air volume is 10000-12000m3 / h. The intelligent wet dust removal device is installed at the discharge point of the coke bin, and a suction port is set at the drop point to introduce moisture, waste gas, dust, ammonia, hydrogen sulfide, etc. at the discharge point into the dust removal device. The waste gas first undergoes primary spray atomization cooling and dust removal of the dust removal device to obtain the waste gas after preliminary dust removal. A high-speed rotating mixing impeller with a diameter of 1-5 meters and a speed of 1500-2000 rpm is used to transport the waste gas after preliminary dust removal to the mixing impeller device. The high-speed rotation of the mixing impeller forms a relative motion with the airflow, so that the waste gas and water are fully mixed, and the ammonia, hydrogen sulfide, dust particles, etc. in the waste gas are fully fused and washed with water. After mixing and washing, a gas-liquid mixture containing air and combustible gas is obtained, which is transported to the dehydration part. Gas-liquid separation is carried out in the dehydration part to obtain purified air and combustible gas. The purified air and combustible gas are recycled and connected to the blast system of the coking pyrolysis device for combustion and coking. The separated muddy water flows back to the sump sedimentation tank through the sewage pipe, and is recycled after sedimentation and filtration, and the sludge is discharged into the sewage treatment system.

[0017] For example, according to the technical parameters and on-site conditions of the coke bin and the coke belt conveyor, the XYZ-1000 intelligent wet dust removal device is selected. The device has a processing air volume of 10,500 m3 / h, which can meet the requirements of 10,000-12,000 m3 / h. The dust removal device is installed at the drop point of the coke bin, and a circular suction port with a diameter of 50 cm is set at the drop point. The moisture, waste gas, dust, ammonia, hydrogen sulfide and other harmful substances generated at the drop point are introduced into the dust removal device by negative pressure. The waste gas first passes through the primary spray part of the dust removal device, and a high-pressure nozzle with a diameter of 1 mm is used to atomize and cool the waste gas to below 50°C, and the collision and adsorption effect of water mist and dust particles is used to remove more than 80% of the visible dust, and the waste gas after preliminary dust removal is obtained. Then, a high-speed rotating impeller with a diameter of 3 meters and a speed of 1800 rpm is used to use the centrifugal force of the impeller to throw the exhaust gas to the periphery and fully mix it with water. The water-gas ratio is controlled at about 1:500, so that the solubility of soluble gases such as ammonia and hydrogen sulfide reaches more than 90%, and the dust removal rate reaches more than 99%. The gas-liquid mixture after mixed washing contains 1% of combustible gas, which is transported to the cyclone separator for dehydration. The recovery rate of combustible gas reaches more than 95%. The calorific value of the recovered combustible gas is 1000-1500kJ / Nm3, which can be used as a combustion-supporting gas for coking pyrolysis equipment, improving energy utilization efficiency by more than 2%. The solid content of the mud water after separation is 5-10%. After filtration through a 100-mesh screen and flocculation precipitation, the SS of the supernatant is ≤50mg / L, which can be recycled. The water content of the sludge is less than 60%, and it is discharged into the sewage treatment system for harmless treatment.

[0018] S104, conveying the washed gas-liquid mixture to a cyclone dehydration device, performing gas-water separation under the action of centrifugal force, and obtaining purified gas containing combustible components and washing wastewater.

[0019] According to the working principle of the intelligent wet dust removal scrubber, the high-temperature wet gas, combustible gas, ammonia, hydrogen sulfide and other waste gases and dust particles during coking are pre-cooled and pre-dusted by atomizing spraying to achieve the purpose of primary purification. The mixing impeller is rotated to form a high-speed relative motion with the airflow, so that the gas and trace dust after primary purification are fully mixed with water, the waste gas and dust particles are fully combined with water, and the ammonia, hydrogen sulfide, dust particles and the like during coking are fully fused with water. After the mixed washing action, the gas containing the combustible component and the gas-liquid mixture after washing enter the dehydration part at the same time. In the dehydration part, a cyclone dehydration device is used to separate gas and water under the action of centrifugal force. After separation by the cyclone dehydration device, two parts of purified gas containing combustible components and washing wastewater are obtained. The purified combustible gas is obtained, recycled through the pipeline, and connected to the blast system of the coking pyrolysis device for combustion and coking. The separated washing wastewater flows back to the sump sedimentation tank through the sewage pipe. The washing wastewater that flows back to the sump sedimentation tank is subjected to sedimentation and filtration treatment, and the water after sedimentation and filtration is recycled. Determine whether there is sludge in the washing wastewater: if there is sludge, the sludge is discharged to the sewage treatment system for subsequent treatment; if there is no sludge, it is directly used in the next cycle.

[0021] S105, transporting the purified gas to a coke oven combustion system through a pipeline to be recycled as fuel.

[0022] According to the working principle of the intelligent wet dust removal and air scrubber, the exhaust gas and dust particles are fully combined with water, so that the ammonia, hydrogen sulfide, dust particles, etc. when the coke is discharged are fully fused with water. After the mixed washing effect is completed, the purified air and combustible gas enter the dehydration part at the same time. The dehydration separation technology is used to separate the purified air and combustible gas from water. The separated purified gas is obtained, and the main components are air and combustible gas. The purified gas is transported to the coke oven combustion system through the pipeline system. If the purified gas meets the fuel requirements of the coke oven combustion system, it is input into the coke oven combustion system as fuel; otherwise, the purified gas is further processed to meet the fuel requirements. According to the operating parameters of the coke oven combustion system, such as temperature and pressure, the delivery flow and pressure of the purified gas are adjusted to match the needs of the coke oven combustion system. During the purified gas delivery process, flow meters and pressure sensors are used to monitor the flow and pressure of the purified gas in real time to ensure its stable supply to the coke oven combustion system. By recycling and utilizing the purified gas, the fuel of part of the coke oven combustion system is replaced, so as to achieve the purpose of energy saving and emission reduction, and reduce production costs at the same time.
