    GS-B-G Series FRP Waste Gas Purification Tower


    DGS-B-G series FRP waste gas purification tower is the new-generation waste gas treatment equipment developed by the company on the basis of the advanced technology of foreign waste gas treatment equipment and more than ten years of experience in manufacturing FRP acid mist purification tower. This series equipment designs general control and automatic control types, meeting different requirements of different customers. Besides, due to compact structure, small size, nice appearance, and low running resistance, the equipment is equipped with a low-power, energy-saving and low-noise fan. This series equipment adopts compact filler spray treatment technique. Tested through motivate production and monitored by the environmental protection department, the equipment is of over 95% purification efficiency as treating hydrogen chloride gas, about 90% as treating sulfuric acid mist, and over 93% as treating alkali mist. Therefore, this series equipment is the domestic most original and ideal purification equipment used in chemical, mechanical, electronic, metallurgical, pharmaceutical industries at present.

    1. Reliable Purification Efficiency

    During R&D process, in order to verify the product property, our company specially invites provincial and municipal environmental protection bureaus to test motivated production of DGS-B-G and gained mass data. Through analysis and classification, the average purification efficiency of hydrogen chloride gas is 96.3%, sulfuric acid mist 93.2% and alkali mist 95%.

    2. Reasonable Structure Design

    DGS-B-G series waste gas purification tower is wet absorption type purification equipment. Its function design is of grouping and grading filler and spray. As it is acid waste gas, sodium hydroxide is used as absorption neutralization solution. As it is alkali waste gas, neutralized water or acid water is used to wash. Its working principle: waste gas is pressed into a balancing chamber composed by outward jackets in purification tower by the fan, through the balancing grating, waste gas enters the primary filler section with constant speed to be treated by the primary spray, which makes sufficient contact between gas and liquid; through the primary treatment, waste gas enters the secondary filler spray section from enlargement section, which makes more sufficient contact between the gas and liquid; and then, after dropping liquid and removing mist by liquid dropper, the tail gas is discharged into the air through the air channel from discharging port. Discharging of the purified tail gas meets regulation of Sheet 2 of Comprehensive Emission Standard of Atmosphere Pollutant GB16297-1996. According to the design principle and function demands mentioned above and compared with other series FRP acid mist purification towers, DGS-B-G waste gas purification tower is improved on its structure design and accessories configuration as follows

    (1) Improving the structure of circulating water pump system and its circulating water tank of the domestic general purification towers.
    a. Selection of circulating water spray pump: circulating fluid spray pump of the domestic general waste gas treatment equipment adopts a horizontal centrifugal pump, which is of the following shortcomings: sealing ring is easy to damage, liquid leakage; serious problems will cause environment pollution of equipment plant and frequent maintenances, and affect operation. Therefore, on the basis of the characteristics of the domestic general corrosive resistant pump, DGS-B-G FRP waste gas purification tower manufactured by the company chooses FYS type and FRPP corrosive resistant fluid pump produced by Shanghai Yong’an Water Pump Factory as circulating water spray pump. This pump is featured by high energy saving, low noise, no leakage, high corrosive resistance, convenient maintenance, and long service life.

    b. Structure of circulating water tankcirculating water tank of DGS-B-G purification tower is the base of the tower. Its main body is connected by flange and tower and it is divided into feed tank and return tank of circulating water. Feed tank is used to satisfy the storage dosage of alkali liquor in the operation of purification tower. Generally speaking, the volume of feed tank is designed to meet requirement of thirty days operation under standard working condition. Besides, it is equipped with a manual dosing port, an automatic feed inlet, a drainage port, etc. Return tank of circulating water is to satisfy the normal operation of purification tower. It is designed with a stationary tank, a return tank, a liquid filter, a supporting seat of circulating water spray pump, a manual maintenance port, a PH probe, an installation hole of liquid indicator, a water filling port, an overflow gate, a drain outlet, a wa
