Description
Technical Field
The invention relates to the technical field of flue gas treatment environment-friendly equipment, in particular to a flue gas treatment environment-friendly system which can control the flow of flue gas, adjust the optimal adsorption flow, track the total amount of activated carbon, and replace the activated carbon and has the functions of flow control and automatic core replacement.
Background
The prevention of adverse effects, due to unexpected negative impact of people on highly developed industries, leads to three global crises: resource shortage, environmental pollution and ecological destruction. Environmental pollution refers to the act of adding a substance to the environment that exceeds the self-cleaning ability of the environment and creates a hazard, either naturally or artificially. The constitution or state of the environment is changed due to human factors, and the quality of the environment is reduced, thereby disturbing and destroying the phenomena of the normal production and living conditions of the ecosystem and human beings. Air pollution: it means that the concentration of pollutants in the air reaches or exceeds the harmful degree, which causes damage to the ecological system and normal survival and development of human beings, and causes harm to human beings and organisms. This is most direct and serious, and carbon monoxide, hydrogen sulfide, and the like mainly emitted from factories, automobiles, power plants, and the like are contaminated with respiratory organs or visual organs by contacting with these contaminated air every day.
The active carbon is prepared by taking carbon-containing substances such as wood chips, shells, lignite and the like as raw materials and carbonizing and activating the raw materials. The particle size of the powder is 10-50 microns, and the particle size of the powder is 0.4-2.4 mm. The general property is porous and the specific surface area is large. The total surface area is 500-1000 square meters per gram. The main performance parameters are adsorption capacity and adsorption rate. The adsorption capacity is the mass of the active carbon per unit weight that can be adsorbed when saturation of adsorption is achieved, and is related to the raw materials, the manufacturing process and the regeneration method. The larger the adsorption capacity, the more economical the amount of activated carbon used. The adsorption rate refers to the mass of the solution that can be adsorbed per unit weight of activated carbon per unit time. Due to the selectivity of adsorption, performance parameters should be determined experimentally. The granular activated carbon should have a certain mechanical strength and particle size specification. The adsorption capacity of different adsorbents to certain molecules of the activated carbon is different at the same temperature and the same pressure. The activated carbon continuously adsorbs the solute in the water until the adsorption equilibrium, i.e. the solute concentration, does not change any more. The relation curve of the weight of solute adsorbed by the unit weight of the activated carbon and the concentration of the solute in the water when the adsorption equilibrium is reached at a certain temperature is called an adsorption isotherm.
For low-concentration flue gas, the activated carbon is used for adsorption and filtration, the purification effect is good, but the adsorption capacity of the activated carbon is poor, the adsorption effect is different under different flue gas flows, the flow is required to be adjusted according to the concentration, and the activated carbon is replaced after the adsorption capacity is saturated. There is a need for an environment-friendly flue gas treatment system with flow control and automatic core replacement functions that can control the flow of flue gas, adjust the optimal adsorption flow, track the total amount of activated carbon, and replace activated carbon.
