Description

Technical Field

[0001] The invention relates to the technical field of waste gas treatment, in particular to a waste gas activated carbon adsorption system and process. Background Art

[0002] Activated carbon adsorption is a common waste gas treatment method. The adsorption method uses porous activated carbon, diatomaceous earth, anthracite, etc. to adsorb organic gas molecules onto their surface for purification. Advantages: high purification rate, practical and convenient, simple operation, low investment. Disadvantages: large wind pressure loss in the system, resulting in high energy consumption, difficult to grasp the saturation point of the adsorbent, limited adsorbent capacity, and high operating dosage.

[0003] Activated carbon is a very good adsorbent. It uses charcoal, various fruit shells and high-quality coal as raw materials, and is processed and manufactured through a series of processes such as crushing, screening, catalyst activation, rinsing, drying and screening by physical and chemical methods. Activated carbon has the dual characteristics of physical adsorption and chemical adsorption, and can selectively adsorb various substances in the gas phase and liquid phase to achieve the purposes of decolorization, disinfection, deodorization, decontamination and purification. The activated carbon adsorption method uses activated carbon as a physical adsorbent to concentrate the harmful substances produced during electrostatic spraying on the solid surface, so that the waste gas can be purified and treated. This adsorption process is a physical process that occurs at the interface between the solid phase and the gas phase.

[0004] Activated carbon is divided into two categories: granular and fibrous. In comparison, granular activated carbon has uniform pores. In addition to small pores, there are also large pores of 0.5 to 5 nanometers. The specific surface area is generally 600 to 1600 square meters per gram. The treated gas diffuses from the outside to the inside over a long distance, so the adsorption and desorption are slow. The adsorption capacity of granular activated carbon that has been oxidized is stronger. Fibrous activated carbon has smaller pores and a larger specific surface area. It relies on the mutual attraction between molecules for adsorption, and does not react chemically with each other. It is a physical adsorption process.

[0005] The activated carbon adsorption device is a device that absorbs hydrocarbons when the waste gas generated during electrostatic spraying passes through the activated carbon layer, and discharges the purified gas into the atmosphere. Small adsorption devices generally use vertical adsorption tanks; large adsorption devices generally use horizontal adsorption tanks.

[0006] As the activated carbon is adsorbed, the resistance of the equipment increases slowly. When the activated carbon is saturated, the resistance of the equipment reaches its maximum value, and the purification efficiency of the equipment is basically lost. For this reason, the system sets up a differential pressure measurement system at the inlet and outlet of the equipment to detect and display the pressure difference of the exhaust gas at the inlet and outlet of the device, and replace the activated carbon in time.

[0007] Since activated carbon can be regenerated, it can be recycled using an activated carbon desorption device when the amount of activated carbon is large, the exhaust gas concentration is high, and the activated carbon adsorption saturation time is short. Using an activated carbon desorption device can not only save operating costs, but also recycle the adsorbed exhaust gas and avoid secondary pollution.

[0008] The adsorption effect of activated carbon adsorption device is affected by many factors, mainly including the following aspects: the properties of activated carbon, the specific surface area, pore structure, surface chemical properties and other factors of activated carbon will affect its adsorption performance. Generally speaking, the larger the specific surface area, the more developed the pore structure and the more active the surface chemical properties of activated carbon, the better its adsorption performance. The properties of waste gas, the temperature, humidity, flow rate, concentration and other factors of waste gas will affect the adsorption effect of activated carbon. Generally speaking, the lower the temperature, the lower the humidity, the slower the flow rate and the lower the concentration of waste gas, the better the adsorption effect of activated carbon. Adsorption time, the longer the adsorption time, the more organic molecules adsorbed by activated carbon, and the better the adsorption effect. However, too long adsorption time will cause activated carbon to be saturated and need to be regenerated or replaced. Operating conditions, operating conditions such as pressure and temperature will also affect the adsorption effect of activated carbon. Generally speaking, increasing pressure and lowering temperature are conducive to improving the adsorption performance of activated carbon.

[0009] For example, application number 202022865906.3 discloses an activated carbon adsorption system for waste gas, including an adsorption tower, both ends of one side of the adsorption tower are provided with a snap-fit ​​groove, and both ends of the other side of the adsorption tower are fixedly installed with connecting rods, and the two ends of the bottom of the front side of the adsorption tower are hinged to the two ends of one side of the filling plate through hinges, and a picking block is fixedly installed at the center of the top of the front side of the filling plate. The utility model is an activated carbon adsorption system for waste gas. The setting of the airtight gasket makes the air duct have good sealing performance, and the installation of the cooling plate in the convex air outlet pipe prevents the convex air outlet pipe from being scalded by excessive exhaust temperature. The air duct evenly distributes the exhaust gas in the adsorption tower, solving the problems of poor air flow and blockage of activated carbon filler. The adsorption towers can be connected in parallel through the snap-fit ​​grooves and connecting rods on both sides. The setting of the connecting grooves and connecting blocks facilitates the series installation of the adsorption towers. The installation methods are diverse, reflecting the flexibility of engineering installation.

[0010] However, most of the current waste gas activated carbon adsorption systems have unreasonable designs for waste gas flow paths. In adsorption chambers of the same volume, the contact area between the adsorbed activated carbon and the waste gas is not ideally designed, resulting in low waste gas treatment rates, large adsorption boxes, high production costs, and low overall automation levels of the equipment. In particular, the replacement of activated carbon is labor-intensive, takes a long time to replace, affects personal safety, and causes serious damage to the environment around the equipment. Summary of the invention

[0014] 2. By setting up an automatic door mechanism, the labor intensity and replacement time of replacing adsorbed activated carbon are greatly reduced.

Compared with manual material replacement, it improves the sanitary environment around the equipment.

[0019] 7. By setting up a water retainer mechanism, the moisture in the gas entering the adsorption box is blocked, effectively preventing the activated carbon adsorption holes from being blocked by the dust and water in the exhaust gas, and effectively preventing the rust of the equipment in the adsorption box.

[0020] 8. By setting up an oscillating cleaning mechanism, the oscillating cylinder impacts the connecting rod, which in turn drives the filter box to vibrate and impact at regular intervals, effectively removing the exhaust gas particles attached to the filter box and the small holes of the activated carbon, thereby improving the utilization rate of the activated carbon and the self-cleaning ability of the equipment.
