High Efficiency 97% Flue Gas Desulfurization Systems High Density Durable

Production Description

Water film Desulphurization Dust Collector (fast-assembling type) is the improvement of traditional granulite water film desulphurization dust collector, with outer lining steel plate, inter lining granite, and middle acid-resistant castable. 1-2 parts are separated transport to site after manufacturing, and assemble at site. It has the advantages of easy installation and short construction period, which is the idea product for boiler and furnace gas desulphurization treatment. While the flue gas enters into the dust collector, alkaline water overflows from upper tower sink. It forms 5mm water film layer on the cylinder wall. The flue gas enters from bottom body with tangential velocity, which provides centrifugal force to make the gas rise and rotate along the wall inside the device. The flue gas gets in touch with water film of the cylinder body under the action of centrifugal force. While the dust is humidified by water film, sulfide reacts with alkaline droplets and flows into the circulation tank with the water from the bottom spillway hole. After purification, gas rises through the upper cylinder cone part and completes the purification process.

Desulphurizer

Considering the origin of desulphurizer, desulfurization effect, operating cost and secondary pollution, NaOH is advised to be desulphurizer. Ammonia water can be adopted as well, however, after purifying; ammonia nitrogen waste water will cause secondary pollution so that post processing is very difficult.

Precautions

1 Before operation, ensure smooth water supply system and open all the valves; Start the pump to inject water inside the tower till great amount of water spills out the overflow port.

2 Start operating induced draft fan; when the boiler shuts down, stop the induced draft fan for some while and then cease supplying water to the device. During operation, water-break and dry burning shall not be allowed inside the towel.

3 Check and clean the dust and slag in sedimentation tank on regular and frequent basis, maintain the quality of recycling water and ensure effective space for sedimentation tank

4 Check the PH value of water in circulating pool regularly, it is suggested that water in sedimentation tank shall be in alkaline condition (PH value shall be kept between 9 and 10)

5 Open the access hole on the towel periodically (generally three to five months), check and clean the dust in time.

6 In case of the intermittent burning in boilers and high density of dust because of the insufficient sediment caused by the small size of water sink, there will be more pressure on the dust collector, adding increasing load on the boiler. It is necessary to check if there is dust in venturi, the inlet of water film desulfurization dust collector and the elbow of back pass and clean it immediately.
