Integral water film desulfurization tower

HXL Type Water Film Desulfurization Dust Collector Introduction

The HXL type water film desulfurization dust collector (quick load module type) is optimized and improved on the basis of the traditional hemp water film tower. The steel plate and granite are perfectly combined into each functional module by high strength anti-permeability and acid-proof castable, and are hoisted and combined on site. It is suitable for all kinds of boilers and kilns because of its advantages such as convenient installation, short construction time, low maintenance cost and long service life.

Working Principle

The dusty gas is introduced tangentially from the lower part of the cylinder and rotates upward. The dust particles are separated by centrifugal force and thrown to the inner wall of the cylinder. Adsorbed by the water film layer flowing on the inner wall of the cylinder, it flows to the bottom of the tower along with the film and is discharged through the overflow port. The water film layer is hung down along the cylinder wall after the water tank on the upper part of the cylinder is full and overflows, and is fully mixed with the rotating flue gas for washing, so as to achieve the purpose of dust removal effect.

Characteristics

1. The cylinder is lined with natural granite with acid resistant castable in the middle. The internal structure is smooth and level to ensure the integrity of the inner water film;

2. The internal anticorrosion adopts heavy anticorrosion, with unique advantages in the aspects of erosion resistance, corrosion resistance and high temperature resistance. The service life of the equipment is more than 10 years;

3. The upper water tank is ceramic structure to ensure no water leakage during the use process;

4. The height of each module is no more than 2m, light weight and convenient installation;

5. Concave and convex joints are adopted between modules, and high strength corrosion-resistant materials are used as sealing treatment to ensure no air leakage and water leakage.

Frequently Asked Questions and Solutions

Reasons for water carry - over in flue gas:

1.The boiler operates beyond its rated capacity.

2.The installed induced draft fan is too large, exceeding the maximum flue gas treatment capacity of the equipment.

3.The equipment is not installed strictly in accordance with the installation instructions. There are air leakage points in the equipment, which suck in a large amount of external air and damage the water film.

4.Ash blocks the inlet of the equipment, causing the flue gas flow rate to be too fast.

5.Ash blocks the inside of the equipment, reducing the inner diameter of the equipment and accelerating the upward flow rate of the flue gas.

Solutions:

1.Over - capacity operation also has a great impact on the boiler. Over - capacity operation of the boiler should be avoided.

2.Reduce the air volume. Valves can be installed or the fan can be frequency - converted.

3.Check all possible air leakage points of the equipment and seal the air leakage points with installation materials.

4.Inspect the equipment and clean the accumulated ash.

5.Inspect the equipment and clean the accumulated ash.

FAQ

1、How long is the service life of the equipment? Is it corrosion-resistant?

Our Model HXL water film tower adopts double protection of natural granite lining + acid-resistant and impermeable castable. The interior is smooth and flat, with excellent anti-scouring, high-temperature resistance and corrosion resistance. Under normal operating conditions, the service life of the whole machine exceeds 10 years, which is more than 3 times that of traditional iron dust collectors!

2、Will the overloaded operation of the boiler affect the equipment?
Yes, it will. When the boiler is overloaded, the flue gas velocity will be too high, which will damage the stability of the water film.
If the induced draft fan is too large, it will exceed the processing capacity of the equipment, causing the "air penetration" phenomenon and reducing the removal dust efficiency.
Suggestion: Avoid long - term overloaded operation. If necessary, the air volume can be adjusted by installing an air valve or the fan can be transformed with frequency conversion to achieve a win - win situation of energy saving and high efficiency.

3、Will dust accumulation affect the equipment? How often should it be cleaned?
Of course! Dust accumulation at the inlet or inside the cylinder will reduce the cross - section of the passage, accelerate the rising speed of flue gas, and cause the water film to break.
If it is not cleaned for a long time, it may also cause blockage and increase the system resistance.
Maintenance suggestions:
Check the inlet and the inside of the cylinder at least once a month.
Clean the dust through the dust cleaning hole in time when dust accumulation is found.
It is recommended to be equipped with an automatic flushing system to improve the intelligent level of operation and maintenance.
