Activated Carbon Adsorption Dry Desulfurization

First, Overview

Flue gas desulfurization equipment can be resource-activated coke dry desulfurization technology is based on the principle of physical - chemical adsorption of sulfur resources recoverable dry desulfurization process, the desulfurization principle is in the range of 120-160 ℃, active coke adsorption flue gas SO2, H2O and O2, produced under the action of active coke sulfuric acid, stored in the active coke microporous, the adsorption of active coke heated to about 400 ℃, adsorption of activated coke in the porous sulfuric acid and active coke in the reaction of carbon, Release of high concentrations of SO2 (concentration of 20% -30%) and regeneration, active coke recycling, the release of high concentrations of SO2 gas using mature chemical technology, can produce a variety of sulfur-like commodity-grade products such as sulfuric acid, sulfur and Liquid SO2 and so on.

SO2 into sulfuric acid adsorption in the active coke pores, while the active coke adsorption layer is equivalent to the efficient particle layer filter, flue gas desulfurization equipment in the inertial collision and interception effect, most of the dust particles in the bed Different parts were trapped to complete the flue gas desulfurization dust purification.

The factory workshop engaged in production operations will produce irritating and other harmful gases contaminants, the nature of the ecological and plant environment will cause air pollution hazards, it is necessary to paint the discharge of waste gas collected after the production of a set of pollution prevention and control equipment, The exhaust gas to meet the air pollutant discharge standards and then discharged into the atmosphere, so as to avoid environmental and personnel hazards.

Activated carbon adsorption tower, is a highly efficient and practical organic waste gas purification and treatment device; is a waste gas adsorption odor odor of environmental protection equipment products. The equipment is the adsorption of high concentration of organic waste gas and paint exhaust gas adsorption equipment, is the use of activated carbon itself, the high strength of the adsorption force, combined with the role of the fan adsorption of organic exhaust gas molecules, the organic solvent exhaust has a good adsorption. The adsorption tower is convenient in the form of material, the surface smoothness is better, the structure is higher, the adsorption capacity is stronger, and has a variety of specifications, according to the different treatment of gas pollution factor design adsorption time, and then according to the size of the amount of waste gas Adsorption area, each project is a new design, to ensure that the adsorption tower in the efficient operation of the state.

Second, the equipment composition and working principle

The equipment mainly by: into the wind section, the tower body, filter, pressure table, the wind section and other components.

The workshop contains organic gas or particles collected by the gas hood, the pipeline transport of organic gas into the activated carbon tower, organic gas into the tower, the wind down down, the gas contains large particles debris will naturally sink into the bottom of the tower, and dissolved The organic gas in the gas enters the activated carbon filter layer with the gas flowing into the activated carbon filter layer. When the organic gas enters the carbon layer, the organic gas is adsorbed into the charcoal by the activated carbon, and the dry air passes through the charcoal layer into the vent chamber, and the gas passes through the mechanical self- And the activated carbon layer in the adsorption process, the carbon will have a saturated period of time, the length of its activated carbon saturation process and the gas itself contains the concentration of gas and the length of time is directly related to the work.

Activated carbon adsorption box is a dry exhaust gas treatment equipment. By the box and filled in the box within the adsorption unit. According to the number of adsorption units and air volume is divided into a variety of specifications, activated carbon adsorption box to choose a different filler can handle a variety of different waste gas.

Active coke dry desulfurization technology process

Activated coke flue gas desulfurization equipment consists of active coke adsorption desulfurization device, desorption regeneration system, desulfurizer conveying system and SO2 gas processing system. Desulfurization tower and regeneration tower is the core of the entire system process.

Activated coke flue gas desulfurization equipment is purified by active coke adsorption desulfurization device and is evacuated, adsorbed SO2 to saturation active coke moving to desorption regeneration system heating regeneration, recycling of high concentration of SO2 mixed gas into the by-product conversion equipment, desorption Of the active coke after screening by the desulfurization agent delivery system into the adsorption desulfurization device again adsorption, active coke to be recycled, while the need to add the right amount of fresh active coke. Damaged active coke particles can be used for industrial wastewater purification. Regeneration system can be heated according to the specific circumstances of the owners to choose steam, electric heaters, hot air stove, etc..

Third, Advantages

1, high adsorption efficiency, strong ability;

2, compact equipment, small footprint, maintenance and management is simple and convenient, low operating costs;

3, can simultaneously deal with a variety of mixed organic waste gas;

4, the use of automated control operation design, easy operation, security;

5, all closed type, both indoor and outdoor use.

Fourth, activated carbon particles

Activated carbon is a black powder, granular or pellet-shaped amorphous porous carbon, the main component of carbon, also contains a small amount of oxygen, hydrogen, sulfur, nitrogen, chlorine. Also has a fine structure like graphite, but the grain is small, irregular accumulation between layers. (500 to 1000 m 2 / g), activated carbon is a very good adsorbent, it is the use of charcoal, bamboo charcoal, a variety of shells and high quality coal as raw materials, through physical and chemical methods of raw materials It is made from a series of processes such as crushing, sieving, catalyst activation, rinsing, drying and screening. It has the physical adsorption and chemical adsorption of the dual characteristics, can be selectively adsorbed gas phase, liquid phase of various substances, in order to achieve bleaching and refining, disinfection deodorant and decontamination purification purposes.

Fifth, application

Applicable to low concentration of high air volume or high concentration of intermittent emissions of the operating environment. The main application areas include: electronic components production, battery (battery) production, pickling operations workshop, laboratory exhaust, metallurgy, chemical plants, pharmaceutical production plants, painting workshop, food and brewing, furniture production and other industries purification, Ideal for paint exhaust treatment. Removal rate can be as high as 90% or more.
