Description

Technical Field

[0001] The invention relates to the technical field of waste gas treatment, and in particular to a high-concentration mixed waste gas recovery and circulation treatment system and process. Background Art

[0002] ‌Waste gas recycling and treatment‌ refers to the process of collecting, purifying and reusing waste gas generated during industrial production. This process can not only reduce the impact of waste gas emissions on the environment, but also improve resource utilization efficiency. The following are the main steps and technologies of waste gas recycling and treatment: ‌Waste gas collection‌: By installing a waste gas collection system, the waste gas generated is collected and concentrated to avoid direct discharge into the atmosphere‌. ‌Waste gas purification‌: The collected waste gas is purified to remove harmful pollutants in it to meet emission standards. Common purification technologies include adsorption, absorption, catalytic oxidation, etc. ‌Waste gas reuse‌: The waste gas after purification can be reused. For example, some waste gas can be used as a source of energy, such as burning waste gas to generate electricity; or used to produce other products, such as using carbon dioxide in waste gas to cultivate algae biomass‌. ‌Heat energy recovery‌: The heat energy carried in the waste gas can be recycled and used for heating, steam generation and other purposes to achieve the purpose of energy conservation‌. ‌Waste gas monitoring‌: Regularly monitor the waste gas to ensure the normal operation of the waste gas treatment system and to detect and solve problems in a timely manner‌. Technological improvement: Continuously develop and apply new waste gas treatment technologies, such as membrane separation and biological treatment, to improve purification efficiency and resource utilization efficiency.

[0003] Specific technical methods for waste gas recycling and treatment include the condensation recovery method: introducing industrial waste gas into the condenser, recovering valuable organic matter through adsorption, absorption, analysis, separation and other links, and purifying the waste gas. Adsorption method: using the adsorption function of the adsorbent to transfer odorous substances from the gas phase to the solid phase. Biological method: using the life process of microorganisms to decompose gaseous pollutants in the waste gas and convert them into harmless substances. Membrane separation method: using the selective permeability of a specific membrane to separate organic matter from the waste gas.

[0004] High-concentration waste gas condensation recovery treatment is an environmentally friendly technology, mainly used to treat high-concentration organic matter in industrial waste gas. This treatment technology can effectively condense and recover organic matter in waste gas, reduce pollution to the environment, and has the value of recycling and reuse. The following will introduce in detail the principles, applications and advantages of high-concentration waste gas condensation recovery treatment.

[0005] The principle of high-concentration waste gas condensation recovery treatment is mainly to utilize the low condensation point of organic matter in the waste gas, and to condense the organic matter into liquid by lowering the waste gas temperature, so as to achieve recovery. During the condensation process, the waste gas first passes through the pretreatment equipment to remove impurities and particulate matter, and then enters the condenser for condensation. The condenser usually adopts a multi-stage cooling method to gradually reduce the waste gas temperature and gradually condense the organic matter into liquid. The condensed liquid can be collected by a collection device, and can be recycled after further purification and treatment.

[0006] High-concentration waste gas condensation recovery and treatment technology is widely used in waste gas treatment in the chemical, pharmaceutical, coating, paint and other industries. These industries will produce a large amount of waste gas containing high-concentration organic matter during the production process, which will cause serious pollution to the environment if directly discharged into the atmosphere. The high-concentration waste gas condensation recovery and treatment technology can recycle and reuse the organic matter in the waste gas, which can not only reduce pollution to the environment, but also reduce production costs.

[0007] High-concentration waste gas condensation recovery treatment technology can effectively recover organic matter in waste gas and reduce pollution to the environment. Compared with the traditional combustion treatment method, this technology does not produce secondary pollution and is more environmentally friendly. The organic matter after condensation recovery can be reused, which reduces production costs and also realizes the recycling of resources. High-concentration waste gas condensation recovery treatment technology is suitable for waste gas treatment in a variety of industries, including chemical, pharmaceutical, coating, paint, etc.

[0008] For example, the application number 202121682208.8 discloses an organic waste gas recovery and circulation treatment system for lubricating oil production, including a shell, a mounting groove is provided at the lower part of the left end of the inner cavity of the shell, a fan is fixedly installed on the right side of the inner cavity of the mounting groove, a first filter groove is provided in the middle part of the left end of the inner cavity of the shell, a first purification groove is provided at the upper part of the left end of the inner cavity of the shell, a detection groove is provided at the upper part of the right end of the inner cavity of the shell, and a gas quality detector is fixedly installed in the inner cavity of the detection groove. The utility model solves the problem that the current lubricating oil will generate organic waste gas in the production process and easily pollute the surrounding environment through the cooperation of the first connecting pipe, the second connecting pipe, the third connecting pipe, the fourth connecting pipe, the fan, the first filter groove, the first port, the first purification groove, the UV ultraviolet lamp, the gas quality detector, the solenoid valve, the second filter groove, the glass fiber filter, the activated carbon filter, the second port and the second purification groove.

[0009] However, most of the current waste gas recovery and treatment systems have solid particles mixed in the waste gas that clog the activated carbon and affect the adsorption effect and the application cycle of the activated carbon. The filter material is replaced frequently, has a short service life, and has a poor filtration effect. The adsorption and desorption processes cannot be switched between each other, resulting in an inconsistency in the waste gas treatment process and the equipment cannot work continuously, resulting in low equipment efficiency. The desorption efficiency of high and low boiling point waste gases adsorbed by the activated carbon is low, the desorption effect is poor, and there is a risk of high temperature. The gases generated by desorption cause secondary pollution, affecting the surrounding environment. Summary of the invention

A process for using a high-concentration mixed waste gas recovery and circulation treatment system comprises the following steps: S1. Exhaust gas enters through the air inlet, passes through the steel mesh filter, the glass fiber filter, and the dense glass fiber filter, and performs three-layer filtration on solid particles in the exhaust gas according to the volume size; the filtered exhaust gas is discharged through the air outlet. When the filter needs to be replaced, the filter can be replaced by pulling out the filter drawing slot plate and taking out the used filter from the embedded slot strip plate; S2. When the exhaust gas is adsorbed, the air inlet control valve and the air outlet control valve are opened, and the filtered exhaust gas enters the adsorption air inlet through the main air inlet pipe, and then enters the adsorption box. After being adsorbed by the activated carbon bricks on the adsorption drawer, the exhaust gas enters the main air outlet pipe through the adsorption air outlet. The exhaust gas after adsorption meets the emission standard and is discharged through the induced draft fan and the emission chimney. S3. When it is necessary to desorb the activated carbon bricks in the adsorption box, close the air inlet control valve and the air outlet control valve, heat the nitrogen in the nitrogen storage tank to a specified temperature through the nitrogen heater, open the nitrogen control valve and the desorption control valve, and allow the heated nitrogen to enter the nitrogen inlet pipe through the nitrogen inlet on the double-control tee, and enter the adsorption box through the desorption inlet to desorb the activated carbon bricks; S4, the condensation medium enters the main condenser in one way and enters the secondary condenser in the other way.

After the exhaust fan acts, the outside air is cooled by the secondary condenser and enters the air cooling zone through the filter screen, and meets the exhaust gas at the spoiler inclined plate to perform gas disturbance and rapid cooling; S5, during desorption, the condensation control valve is opened, and the waste gas generated by desorption enters the condensation pipe through the condensation outlet, enters the condensation box through the condensation inlet for cooling and condensation, and the condensed liquid wastewater flows into the liquid outlet through the guide groove, and is pumped into the liquid storage tank; S6. When desorption is completed, the condensation control valve and the nitrogen control valve are closed, and the cooling control valve and the air outlet control valve are opened. The wind passes through the recoil cooling air cooler and the cooling air inlet on the double-control tee, and then enters the nitrogen air inlet pipe, and then enters the adsorption box. After cooling the adsorption box, the wind enters the main air outlet pipe through the adsorption air outlet, and is discharged from the induced draft fan and the exhaust chimney. S7, when the temperature reaches the set temperature, close the cooling control valve, open the air intake control valve, and then enter the adsorption working mode; the control valves on the two groups of adsorption boxes are divided into two groups according to adsorption and desorption condensation cooling, and work alternately; Compared with the prior art, the present invention has the following beneficial effects: 1. By setting up a layered pretreatment mechanism, the problem of solid particles mixed in the exhaust gas clogging the activated carbon and affecting the adsorption effect and the application cycle of the activated carbon is effectively avoided. By designing a three-layer filtration method of steel mesh filter, glass fiber filter, and encrypted glass fiber filter, the solid particles in the exhaust gas are filtered layer by layer according to their volume, which reduces the replacement frequency of the filter material, improves the filtration effect, and increases the service life. By designing the filter pull-out slot plate and embedded slot strip plate, the convenience of replacing the filter material is improved and the labor intensity is reduced.

[0013] 2. By setting up a double-station adsorption mechanism and using two sets of adsorption boxes, they can switch between each other during the adsorption and desorption processes to ensure continuous operation of the equipment, greatly improving the working efficiency of the equipment. The adsorption box is divided into a left adsorption chamber and a right adsorption chamber by designing a middle partition. The adsorption material can be placed as needed, controlling and saving the amount of activated carbon while increasing the adsorption range, effectively avoiding the problem of limited production capacity caused by a sudden increase in production capacity.

[0014] 3. The adsorption box is designed with three layers of outer protective sheet metal, rock wool board, and insulation layer gusset plate, which effectively improves the insulation and leak-proof performance of the adsorption box while ensuring the rigidity of the adsorption box, and improves the durability of the equipment. The convenience of replacing activated carbon is improved by designing a sealed door, adsorption tray rack, and adsorption drawer.

[0015] 4. By setting up a high-temperature nitrogen desorption mechanism, nitrogen is an inert gas. The desorption temperature can be set at about 180 degrees by using nitrogen desorption. It can quickly and efficiently desorb the high and low boiling point exhaust gases adsorbed by the activated carbon, so that the activated carbon can be effectively and efficiently regenerated. Desorption under high temperature conditions with inert gas nitrogen ensures that there is no hidden danger of fire during desorption, and achieves safe and reliable operation.

[0016] 5. By setting up a rapid condensation box mechanism, the organic matter in the exhaust gas can be effectively condensed and recovered, reducing pollution to the environment, and has the value of recycling and reuse. The entire desorption process is set up with condensation recovery and activated carbon adsorption to achieve full internal circulation, without external gas discharge, no secondary pollution, and no impact on the surrounding environment.

[0017] 6. By setting up cold air inlet, secondary condenser, exhaust fan and spoiler inclined plate, the exchange speed and exchange area between the exhaust gas and the refrigerant inside the condensation box are increased while reducing the refrigerant consumption, thereby increasing the condensation speed and reducing the energy consumption of the equipment.

[0018] 7. By setting up a recoil cooling air fan, after the high-temperature desorption is completed, the recoil cooling air fan is used to quickly cool the inside of the adsorption mechanism and the adsorption material, thereby improving the operating efficiency and work switching efficiency of the equipment.

[0019] 8. By setting the air intake control valve, air outlet control valve, desorption control valve, condensation control valve, nitrogen control valve and cooling control valve, automatic control is adopted for the waste gas adsorption, desorption and condensation processes, which improves the automation degree of the equipment, improves the fineness of the waste gas treatment of the equipment, and effectively avoids the generation of treatment residues.

The main condenser 506 cools and condenses the exhaust gas entering the condensation zone 503. After the exhaust fan 509 acts, the outside air is cooled by the secondary condenser 508 and enters the air cooling zone 504 through the filter 510, and meets the exhaust gas at the spoiler inclined plate 511 to cause gas disturbance and rapid cooling; S5, during desorption, the condensation control valve 314 is opened, and the waste gas generated by desorption enters the condensation pipe 515 through the condensation outlet 313, and enters the condensation box 502 through the condensation inlet 505 for cooling and condensation, and the condensed liquid waste water flows into the liquid outlet 513 through the guide groove 512, and is pumped into the liquid storage tank 514; S6.
