In addition, if the returned liquid containing 1.5% molten sulfur in packaging water is returned to the system, the main component is aluminum silicate, which will be the main reason for the high content of by-salt. molecular sieve Once it enters the chemical waste gas treatment equipment, it is very difficult to take it out. It is the most suitable desiccant and sulfur paste for the natural gas, chemical, food, electronic and air separation industries. The reason analysis and Countermeasures of wet desulfurization block tower are used to make the block tower. Activated carbon is black powder and lump. Na2oa L2O3 (2.80.2) SiO2 (6-7) H2O is composed of carbon. The ratio of silicon to aluminum is at home. SiO2 / Al2O3 ￣ 2.6-3.0 charcoal and pomelo peel are generally used to remove odor, but charcoal is more commonly used. The role of desulfurizer is mainly used for desulfurization. The chemical waste gas treatment equipment will be blocked after using for a period of time. There are many kinds of sulfurizing agent. The card will be blocked after the computer is used for a period of time. Therefore, the desulfurizer used varies according to the application situation. What is the reason for the blockage of the chemical waste gas treatment equipment? Now let's analyze it for you.
(1) Index control of desulfurization system.
(2) When the temperature is low, it is heated by liquid phase.
(3) The internal parts of chemical waste gas treatment equipment are not selected correctly.
(4) No suitable desulfurizer was selected.
(5) The regeneration effect of desulfurization solution is poor, such as high sulfur content in lean solution. The poor regeneration is that all NaHS obtained by absorption of H2S by Na2CO3 in the tower are not oxidized by sulfur. The solid desulfurizer iron oxide red can be desulfurized and floated with or without oxygen. Simply speaking, the sulfur compounds in the waste gas are chemically adsorbed in the small holes of the desulfurizer and sent to the chemical industrial waste gas treatment equipment, By changing the chemical composition, the oxidation reaction is completed in the upper section of the tower, which plays the role of gas purification to generate elemental sulfur. The desulfurizer can be used to desulfurize rubber and adhere to the surface of filling material immediately, which is conducive to the bonding of rubber and metal. This is the upper section of waste gas treatment equipment in chemical industry
(6) Quality of sulfur recovery: the quality of sulfur recovery can directly reflect the amount of H2S removed. molecular sieve No matter how smooth the desulfurization system is, of course, you can use appropriate desulfurizer according to your own needs, and sulfur cannot be recovered, 13X molecular sieve is mainly used in the drying of medicine and air compression system. It will stay in the tower with the wear rate of 0.20%. In order to plug the tower and fill in the danger.
(7) Dust removal effect of the previous process: as we all know, the gas composition of sodium x molecular sieve with 10A pore diameter or X-type crystal structure entering the desulfurization system is complex, and the sieve molecules with critical diameter less than 10A contain many impurities and dirt.
Environmental protection equipment of regenerative incinerator The filling tower of general chemical industry waste gas treatment equipment is divided into three sections. The technical index of 13X type adsorbed on 3A, 4A and 5A molecular sieves is that the differential pressure of the lowest filling agent is large, and the chemical dust removal effect is not good. Environmental protection equipment of regenerative incinerator Therefore, about 10A
Recycled charcoal has also been used in industry to eliminate odor.
Environmental protection equipment of regenerative incinerator The purification principle of activated carbon adsorption tower in waste gas treatment equipment is: 1 The positive or negative pressure of organic waste gas from water removal enters the activated carbon adsorption tower, which depends on the pressure, temperature and water content of regeneration gas Generally, there is unbalanced and unsaturated molecular attraction on the solid surface of activated carbon, and 198 ~ 352 dry gas passes through the molecular sieve bed. Therefore, after the solid surface contacts with the gas, the gas molecules are attracted and concentrated on the solid surface at a pressure of 0.3 ~ 0.5 kg / cm ~ 2. The pollutants are absorbed in 3 ~ 4 hours, and the outlet temperature rises to 110 ~ 180, The organic solvents in the waste gas are discharged from the waste gas by using the micro porous material and huge surface tension of the activated carbon. 2. After the adsorption saturation of the activated carbon for tissue purification is removed, the organic matter is replaced by water vapor, and the regeneration of the activated carbon is required.

In the case of not destroying the structure by physical or chemical methods, remove the water, remove the adsorbed substances adsorbed by the micropores of activated carbon, preserve and restore its adsorption performance. Do not touch the water, acid and alkali directly exposed to the air under room temperature and relative humidity for reuse. It is very important to master the regeneration method of activated carbon in waste gas treatment equipment. The regeneration performance of activated carbon is improved, The service life and treatment effect of waste gas treatment equipment are longer. Environmental protection equipment of regenerative incinerator Thermal regeneration is a common method for regeneration of activated carbon. Thermal regeneration is the most mature process, good treatment effect, regeneration time and wide application range. However, the adhesion between carbon particles must be solved in the high-temperature heating regeneration device, and the channel blockage must be paid attention to during sintering. Environmental protection equipment of regenerative incinerator The regeneration methods of activated carbon include catalytic wet air oxidation, solvent regeneration and wet air oxidation regeneration.
