Analysis of the Absorption-Dehumidification Process Variables Using the Experimental Design Methodology

Abstract: A spray tower in the absorption-dehumidification process was designed to study the separation of water vapor from moist air. The performance of the absorption tower was evaluated under various operating parameters. The role of each operating parameter and the relationship between the parameters are still unknown. A second-order polynomial model with a multiple linear regression was used to estimate the model coefficients. The model coefficients of the five selected parameters, including air- and liquid-flow rates, liquid concentration and temperature, and orifice diameter of nozzles were proposed to study the influence of these factors on the response of the mass-transfer coefficient. A factorial design model of the five variables is discussed in a two-level analysis. Only 32 (or 25) experimental runs were necessary to assess these variables and the model satisfied the process very well since the coefficient of determination (R2) was very close to 1. The influence of operating parameters on mass-transfer ...

Abstract: The utility model relates to a high-efficiency flue gas dust-removal desulfurization device. The high-efficiency flue gas dust-removal desulfurization device comprises primary and secondary desulfurization units, primary and secondary absorption solution circulating pools and a demister, wherein the primary dust-removal desulfurization unit is a fair concurrent spray tower, and the lower part of the fair concurrent spray tower is provided with the primary absorption circulating pool; the secondary dust-removal desulfurization unit is the fair countercurrent spray tower, and the lower part of the countercurrent spray tower is provided with the secondary absorption solution circulating pool; and the primary absorption solution circulating pool and the secondary absorption solution circulating pool are in an integrated structure, and an overflow device is arranged between the primary absorption solution circulating pool and the secondary absorption solution circulating pool to ensure that the absorption solution of the secondary absorption solution circulating pool flows into the primary absorption solution circulating pool. Compared with the prior art, the high-efficiency flue gas dust-removal desulfurization device has the advantages of small occupied space, low investment, high desulfurization efficiency and the like.

Gas, solid and liquid integrated combustion system

Abstract: The invention relates to a gas, solid and liquid integrated combustion system, and belongs to the technical field of the environment. The system is composed of a waste gas collection system, a granulation system, a feeding system, a rotating furnace, a combustion furnace, a waste heat boiler, a heat exchanger, a rapid quenching tower, a smoke dry type washing system, a cloth bag dust removal device, a spray tower, a reheater and a chimney. Coal, solid waste and liquid waste are evenly mixed according to the mass ratio (1-12):(2-30):(1-16) in the granulation system for granulation; after collected waste gas is preheated, part of the waste gas enters the rotating furnace, and the other part of the waste gas enters the combustion furnace to be processed through high temperature combustion; high temperature tail gas of the combustion furnace enters the rapid quenching tower, the dry type washing system, the cloth bag dust removal device and the spray tower after heat energy recovery, and is sent to the chimney by a draught fan after the tail gas is cooled and fly ash, dioxin and acid gas are removed, so that emission reaching the standard is completed. Liquid waste produced in the running process of the system is recycled in the granulation system, solid waste such as activated carbon is fed into the rotating furnace to be combusted, and therefore harmless treatment is achieved while running cost of the system is reduced.

Process method for manufacturing manganese products through high-concentration SO2 smoke leaching manganese ore pulp

Abstract: The invention discloses a process method for manufacturing manganese products through high-concentration SO2 smoke leaching manganese ore pulp. The process method mainly comprises the steps that high-concentration SO2 smoke enters from a first-stage tower segment of a multi-stage spray tower, manganese ore pulp liquid enters from a last-stage tower segment of the multi-stage spray tower, in each-stage tower segment, the smoke enters from the lower portion of the tower segment to be subjected to a contact reaction with the manganese ore pulp liquid sprayed down from the top, and a proper amount of air is blown into the tower bottom to reinforce desulfuration and leaching of manganese. The manganese ore pulp liquid subjected to full leaching is finally discharged out of the first-stage tower segment, a manganese sulfate solution product is obtained, the fully-desulfurated smoke is exhausted out of the last-stage tower segment, the content of SO2 reaches the standard, and the smoke is directly exhausted into air. The smoke with unqualified SO2 content enters a deep desulfurization tower, and SO2 in gas continues to be removed till the content of SO2 reaches the standard. The operating temperature of the contact reaction ranges from 70 DEG C to 85 DEG C, and pH ranges from 2 to 3. The method has the advantages of being high in resource utilization rate, high in desulfuration efficiency, high in manganese leaching rate, high in adaptability to manganese oxide ore, low in cost and the like.
