Description

Technical Field

[0001] The present invention relates to the field of waste gas treatment equipment, and more specifically, to a VOCs adsorption equipment capable of measuring VOCs concentration online. Background Art

[0002] Volatile organic compounds, commonly referred to as VOCs, are various organic compounds with boiling points between 50°C and 260°C at room temperature. They mainly include non-methane hydrocarbons, oxygen-containing organic compounds, halogenated hydrocarbons, nitrogen-containing organic compounds, sulfur-containing organic compounds and other categories. VOCs participate in the formation of ozone and secondary aerosols in the atmospheric environment, and have an important impact on regional atmospheric ozone pollution and PM2.5 pollution. Most VOCs have a special unpleasant odor and are toxic, irritating, teratogenic and carcinogenic. Benzene, toluene and formaldehyde, in particular, can cause great harm to human health. Therefore, waste gas containing VOCs must be discharged after the VOCs component is removed. VOCs adsorption equipment is a device that removes VOCs components in waste gas.

[0003] The existing VOCs adsorption equipment is composed of a shell, a filter, adsorption particles, etc. When in use, the filter first filters out the particulate matter in the exhaust gas, and then the adsorption particles adsorb and fix the VOCs components in the exhaust gas, thereby achieving the purpose of removing the VOCs components in the exhaust gas. However, the filter needs to be replaced and maintained frequently, which is time-consuming and labor-intensive, and the disassembly and assembly method of the filter is relatively cumbersome, resulting in more time-consuming and labor-intensive maintenance work. At the same time, the replacement and maintenance work requires the interruption of the exhaust gas treatment process, resulting in low exhaust gas treatment efficiency. Therefore, it is urgent to design a VOCs adsorption equipment that can measure the VOCs concentration online. Summary of the invention

[0017] 3. Beneficial effects

[0018] Compared with the prior art, the advantages of the present invention are:

[0019] ① Through the adsorption purification device, the VOCs adsorption equipment can detect the concentration of VOCs in the exhaust gas, so that people can make corresponding responses according to the VOCs concentration. Through the exhaust gas pretreatment component, the VOCs adsorption equipment can remove particulate matter in the exhaust gas to avoid the adverse effects of particulate matter on subsequent exhaust gas treatment work. By replacing the components, people can more conveniently disassemble and assemble the components consisting of the left mounting cap, the right mounting cap, the docking short pipe, and the pretreatment network pipe, which helps to simplify maintenance work and save time and effort. Through the performance maintenance component, the components consisting of the left mounting cap, the right mounting cap, the docking short pipe, and the pretreatment network pipe can be driven to rotate, so that the intercepted objects on the surface of the pretreatment network pipe can be thrown off under the action of centrifugal force to maintain the permeability of the pretreatment network pipe, which helps to reduce the maintenance frequency, increase the exhaust gas treatment efficiency, and help to further simplify the maintenance work. Through the maintenance integrated component, people can clean the intercepted objects without interrupting the exhaust gas treatment process. On the one hand, it can increase the exhaust gas treatment efficiency, and on the other hand, it can simplify the maintenance work again, thereby improving the practicality of the VOCs adsorption equipment.

[0020] ② The flow-cutting and overflow-proof components can control the opening and closing of the shunt airway to ensure that when the components consisting of the left mounting cap, the right mounting cap, the docking short pipe, and the pretreatment network pipe are taken out, the flow-cutting and overflow-proof components will block the shunt airway to prevent exhaust gas leakage. When the components consisting of the left mounting cap, the right mounting cap, the docking short pipe, and the pretreatment network pipe are installed in place, the shunt airway is opened to pre-treat the exhaust gas. There is no need to manually control the opening and closing of the gas source, which simplifies maintenance work and helps to increase the exhaust gas treatment efficiency. The non-return component allows the gas to flow in one direction to prevent the pre-treated exhaust gas from leaking during the maintenance of the pretreatment network pipe. The component adsorption mechanism can purify the VOCs components in the exhaust gas, and it is convenient for people to replace the component adsorption particles, which simplifies maintenance work. The continuous processor can control the airflow so that when the adsorption bearing cylinder inside the side adsorption column tank is drawn out, no exhaust gas will enter the side adsorption column tank, which prevents exhaust gas overflow, and the process of replacing the component adsorption particles will not interrupt the exhaust gas treatment process, which helps to increase the exhaust gas treatment efficiency and further improve the practicality of the VOCs adsorption equipment.

[0046] Working principle:

[0047] First, the driving fan 108 is turned on through the integrated control box 104, and then the exhaust gas enters the online measurement chamber 105 through the exhaust gas suction pipe 109, the driving fan 108, and the gas short pipe 107 driven by the driving fan 108. Then the online detection head 106 detects the concentration of VOCs in the exhaust gas in real time and sends the detection result to the integrated control box 104. After that, the integrated control box 104 displays the detection result so that the workers can know the detection result. Then the exhaust gas inside the online measurement chamber 105 enters the exhaust gas pretreatment chamber 21 through the diversion airway 22, and then the exhaust gas enters the interior of the pretreatment network pipe 28 through the channel on the pretreatment network pipe 28 and applies thrust to the non-return tapered cone plug 96 under the action of the air pressure difference. At the same time, the pretreatment network pipe 28 The particles are intercepted, and then the non-return tapered cone plug 96 slides with the non-return guide plug 95 inside the non-return column cavity 91, and then the non-return guide plug 95 squeezes the non-return spring 94, and then the non-return spring 94 is elastically compressed, and the elastic potential energy increases, and then the non-return tapered hole 92 is opened, and then the exhaust gas passes through the non-return tapered hole 92, the non-return column cavity 91, the overflow flow groove 97, and the transmission air pipe 407 into the interior of the accommodating groove 403, and then the exhaust gas passes upward through the transition channel 402 and the wind drive channel 401 into the interior of the air distribution chamber 400, and then the wind impeller 406 rotates in the airflow, and then the wind impeller 406 rotates with the linkage vertical rod 404, and then the linkage vertical rod 404 rotates with the linkage bevel gear 405, and then the linkage bevel gear 405 passes The transmission air pipe 407 is rotated by the meshing action between it and the transmission bevel gear 408, and then the transmission air pipe 407 rotates with the angular column 409, and then the angular column 409 rotates with the right mounting cap 26 through the plug-in action between it and the angular through hole 410, and then the right mounting cap 26 rotates with the pretreatment network tube 28 through the docking short tube 27, and then the particles intercepted on the surface of the pretreatment network tube 28 are thrown off under the action of centrifugal force and fall into the inside of the tapered gathering groove 501, and then the particles are gradually gathered on the top surface of the centering tray plug 503, and then the pretreatment network tube 28 rotates with the left mounting cap 24 through the docking short tube 27, and then the left mounting cap 24 rotates with the rotating short column 411, and then the exhaust gas inside the air distribution chamber 400 The exhaust gas passes through the branch flow hole 82, the gradually expanding groove 81, and the bottom inlet hole 705 to enter the adsorption bearing tube 704 inside the side adsorption column groove 702, and then the exhaust gas flows upward inside the adsorption bearing tube 704. At the same time, the exhaust gas flows upward in the internal gap of the component adsorption particles 706, and then the component adsorption particles 706 adsorb and fix the VOCs in the exhaust gas to form purified gas. Then the purified gas emerges from the top of the component adsorption particles 706 and passes through the channel on the ejection porous ring 707 to enter the side adsorption column groove 702, and then the purified gas passes through the centripetal one-way valve 703 to enter the central interception column groove 701, and then the purified gas enters the corresponding adsorption bearing tube 704 through the channel on the ejection porous ring 707 inside the central interception column groove 701.Then, the exhaust gas detection head 711 detects the concentration of VOCs in the purified gas, and then the exhaust gas detection head 711 transmits the detection result to the integrated control box 104, and then the integrated control box 104 displays the detection result in real time, and then the purified gas passes downward through the gap in the corresponding component adsorption particles 706 and enters the transmission groove 712 through the bottom inlet hole 705.
