working principle:

After the boiler flue gas containing dust and sulfide enters the venturi throat, the static pressure in the pipe drops to a low value and remains unchanged due to the unchanged throat cross-sectional area, and the airflow velocity reaches a high value at this time; The airflow enters the diffuser. As the cross section area expands gradually, the static pressure in the tube gradually recovers and the airflow velocity gradually decreases. The washing liquid is introduced at the end of the shrink tube or throat through a nozzle, where the air velocity is very high. Under the impact of high-speed air flow, the alkaline washing liquid sprayed from the nozzle is further atomized into smaller droplets, and the relative velocity of gas, liquid, solid (particle dust) is very large, so that they can be more fully mixed, Thus, the chance of mixing sulfur dioxide and alkali droplets is increased, so that most of the sulfur dioxide and alkali droplets can fully react to achieve the purpose of desulfurization. On the other hand, due to the sufficient atomization of alkaline detergent, the gas reaches saturation, thus destroying the gas film on the surface of the dust particles, so that the dust particles are completely wetted by water vapor. When the gas enters the diffusion tube, these dust particles and droplets wetted by water at www.tfzs01.com, as well as dust particles or droplets with different particle sizes, under the action of different inertial forces, condense into dust droplets with larger particle sizes in the process of collision and contact. These coarse dust droplets enter the main tower with the air flow and are separated from the air flow under the action of gravity, inertial force and centrifugal force, so as to achieve the purpose of purification.

Product features:

1. It is made of natural granite and machined into a round bending plate. The overall structure is smooth and flat, with corrosion resistance, wear resistance and high temperature resistance.

2. The exterior shall be poured with high strength, high temperature, acid and alkali resistant materials. The outer steel plate of the barrel equipment greatly enhances the strength and service life of the equipment.

3. The upper water tank is of ceramic structure, ensuring no water leakage during the water supply process, avoiding the overflow problem of the original granite dust collector water tank, and enhancing the use effect of the dust collector.

4. The interior is flat and smooth, reducing the good water volume to 2/3 of the original, and reducing the operating cost.

5. The installation is simple. Generally, each section is 1m long, and the installation can be completed within half a day of on-site hoisting, reducing the construction period.

6. The body adopts a 1m structure in each section, and there are concave convex joints at each joint. During installation, acid resistant mastic is used to connect the joints to ensure no water leakage at the joints; It overcomes the common problems of water seepage and air leakage of the original granite dust collector.

7. Because the water film desulfurization dust remover is light, the cost of foundation and transportation is reduced.

8. The outlet is equipped with a companion flange, and the joint of the flange is filled with asbestos rope during installation to prevent air leakage and affect the treatment effect
