Desulfurizing spray tower

Abstract: A desulfurizing spray tower belongs to the technical field of boiler flue gas desulfurization and comprises a spray layer and a flue inlet, wherein a Venturi rod layer with multilayer structure is arranged between the spray layer and the flue inlet, Venturi tubes between two adjacent layers are vertically positioned, and each Venturi rod layer is composed of a plurality of Venturi tubes which are equidistantly arranged on a holder. Based on the prior spray tower, the Venturi rod layers are added in the desulfurizing spray tower of the utility model, the rod layers can lead flue gas to be evenly distributed on the tower cross-sectional area and to form strong turbulent flow, therefore the gas-liquid mass transfer effect is strengthened, the absorbent surface is unceasingly renewed and the utilization ratio of desulfurizer is enhanced. Furthermore, the Venturi rod layer is an independent and complete component, thus the gas-liquid mass transfer is guaranteed to be steadily finished by an absorbing tower even though the flow quantity of flue gas is low. Under the circumstance of same liquid-gas ratio, the desulfurizing spray tower has higher desulfurization efficiency, when having same desulfurization efficiency, and the desulfurizing spray tower can reduce the quantity of circulation pump serous fluid by 20 to 50 percent.

Sintering fume seawater desulfurization tower

Abstract: The utility model provides a sintering fume seawater desulfurization tower, which comprises a tower body, a fume inlet, a dust removal and storage system, a gas outlet, a mist eliminator, a spray tower atomizer, a liquid storage cavity, a liquid outlet and the like. The sintering fume seawater desulfurization tower is characterized in that the tower body is composed of a main tower and an auxiliary tower, an active carbon absorbing auxiliary tower is arranged in front of a spray atomizer of the main tower, the main tower is communicated with the lower end of the auxiliary tower to form a U-shaped fume channel, the fume inlet is arranged at the upper part of the auxiliary tower, the dust removal and storage system is arranged at the lower part of the auxiliary tower, the gas outlet is arranged at the upper part of the main tower, the cavity of the main tower is provided with the mist eliminator and the spray tower atomizer, and the liquid storage cavity and the liquid outlet are arranged at the lower part of the main tower. The sintering fume seawater desulfurization tower is designed for the pretreatment of dioxin and heavy metal ions in the sintering fume, the treated fume is absorbed and purified by the seawater after passing through the seawater desulfurization tower, and finally reaches the standards and is emitted, as the seawater is only used as the desulphurizer in the desulfurization process, the operating cost is reduced and no secondary pollution is caused to the ocean.

Coal smoke dusting and desulfurizing appts.

Abstract: Disclosed is a dust removal and sweetening device, formed by consecutive connection of a whirlwind collector, an exhauster, a crushed granite spray tower and a smoke window via tubes. The crushed granite spray tower has a crushed granite structure, multiple layers of turbo-grid plates are arranged in the tower, and raschin rings are arranged on the turbo-grid plates. The top of the tower is provided with a spraying head, water sealing orifice is opened at the bottom portion of the tower, a liming tank and a precipitating tank are arranged at the lower portion of the water sealing orifice outside the tower, and the water in the precipitating tank is pumped into the spraying head arranged at the top of the tower via pump for circular use. The utility model has the advantages of low investment of arrangement, low running expense, long working life of equipment, quick effects of blowing in of equipment, simple operation and maintenance, and perfect dust removal and sweetening effects.

Humidification technology and humidification system for large power PEM fuel battery test platform

Abstract: This invention puts forward a design plan for wetting technology and system used in test platforms of large power fuel cells, which puts forward a heat-exchange system of two stages or multiple stages to transfer heat generated by fuel cells to reactant gas entering into the fuel cell, in order to increase the gas/liquid medium-transfer ability of the wet system, a high efficient filled converse flow spray tower is taken as a main wetting device and temperature of a spray medium is controlled accurately to guarantee temperature of wetting and saturation of vapor, which can control the relative humidity of the reactant gas entering into a fuel cell stack within +-2% and relative temperature in +-0.1deg.C by controlling the temperature of an overheater with an outer heater and efficient heat-transmitting filling component accurately, and a foam-removing system with accurate temperature control is matched to avoid liquid from entering into the back system.
