Boiler desulfurization tower

The desulfurization tower of boiler is a kind of desulfurization dust remover with low pressure loss and dust removal. The desulfurization tower is mainly composed of cylinder, spray device, sieve plate, dehydration and demisting device, overflow hole, cleaning hole, etc.

Details:

The desulfurization tower of boiler is a kind of desulfurization dust remover with low pressure loss and dust removal. The desulfurization tower is mainly composed of cylinder, spray device, sieve plate, dehydration and demisting device, overflow hole, cleaning hole, etc. Its working principle is: the flue gas containing dust and sulfur oxide enters the cylinder through the flue, and the alkaline absorption solution containing [OH -] ions is ejected from the upper, middle and lower parts of the bubble dust removal and desulfurization tower by spiral nozzle, forming multiple rows of high-speed atomization water curtain in reverse with the flue gas, increasing the collision probability of flue gas sulfur oxide and water, and making full use of the speed of atomizing droplets to create very high gas Liquid relative velocity to the dust removal and desulfurization effect of the dust collector. At the same time, when the gas passes through the sieve plate, the liquid layer on the sieve plate is bubbled, which increases the surface area and turbulent state of gas-liquid mass transfer, and improves the mass transfer rate. The gas-liquid mass transfer occurs between sulfur dioxide and alkali liquor, which further improves the effect of desulfurization and dust remover. The desulfurized products will flow to the bottom of the desulfurization tower and be discharged from the overflow hole. A water seal groove is set at the bottom of the cylinder body to prevent the flue gas from leaking from the bottom. In addition, a cleaning hole is provided to facilitate manual cleaning and sedimentation at the bottom of the cylinder (or automatic ash removal). The desulfurization wastewater is discharged from the bottom overflow hole into the sedimentation tank for sedimentation neutralization and recycling (double alkali process). The purified gas is discharged through the upper part of the cylinder through the demister, so as to achieve the purpose of dust removal and desulfurization. Since its establishment, our company has been adhering to the "quality for life, service for the fundamental" business philosophy, to "honest life, work, integrity management, service" purposes, adhere to the "quality" principle, to, and high requirements to manufacture each product, customer satisfaction. FRP desulfurization dust remover is a new product, No. Using Doyle principle and new dehydration technology, after nearly ten years of use and new transformation, new anticorrosive materials have been selected, and environmental protection products with mature technology have been formed. Glass fiber reinforced plastic (FRP) dust remover is widely used in dust removal and desulfurization of coal-fired boilers in urban and rural areas. With dust removal and desulfurization, small floor area. It has the advantages of low operation cost, easy operation and maintenance, and small water consumption, which is well received by users and environmental protection departments. Tower type equipment is the main equipment for desulfurization treatment of industrial waste gas, namely desulfurization tower. Its initial desulfurization, also known as granite desulfurization membrane dust remover, is widely used for water desulfurization. It has the advantages of easy maintenance, and can achieve the effect of dust removal and desulfurization (denitrification) at the same time through the preparation of different dust removers. Now with the development of FRP technology, FGD tower is gradually made of FRP. Compared with granite desulfurization tower, FRP desulfurization tower has the advantages of low cost, easy processing, no rust and no rot, light weight, so it becomes the development trend of desulfurization tower in the future.

Features of boiler desulfurization tower

1. FRP dedusting and desulfurization tower has the characteristics of corrosion, light weight, high strength and long service life. The product adopts split combination type, which is convenient for transportation and installation. The main body of the dust removal tower is made of modified resin matrix composite material. Ordinary resin composite products have poor temperature resistance and are not suitable for the main material of dust removal tower. Because of the use of resin composite material and its modification treatment, and the main body of the dust removal tower uses large winding equipment for one-time molding, which greatly increases the strength of the equipment, so that SCT series dust removal and desulfurization tower has high strength and other performance, and the maintenance rate is almost zero under normal standard operation.

We know that: the decay coefficient of resin is generally 10-20 years. The dedusting and desulfurizing tower developed by our company is an organic combination of other materials, and other performances of the dust remover are comprehensively considered. In addition to this characteristic, the FRP dedusting tower also has a layer in the equipment, which greatly improves the service life of the dust remover. The structure of the product is scientific and reasonable split design. This novel and exquisite structure facilitates the transportation and installation of users, and saves manpower and material resources and daily maintenance.

2. Glass fiber reinforced plastic dedusting and desulfurization tower is equipped with scientific impeller dehydrator, which can save energy and reduce consumption. Centrifugal force principle is used for dehydration. Impeller dehydration equipment does not need power energy and there are no moving parts in the equipment. Thus, the operation performance and stability are improved, the loss is reduced and the maintenance cost is reduced.

3. The dust removal tower has the characteristics of dust removal and desulfurization, in addition to the large specific area of liquid gas contact in the room. The experimental results show that the liquid gas ratio L / g = 0.4KG cubic meter, the desulfurization efficiency can reach more than 90%.

4. Compared with other dust collectors, the pump is saved and the operation cost is reduced by using the working principle of inertia and impact.

5. Equipment dust removal and desulfurization integration, water consumption is small, sodium hydroxide, industrial alkaline waste water or slag water, boiler sewage waste water can be used as desulfurizer, which not only saves energy, but also has no secondary pollution. According to the test in the industrial products laboratory, the FRP dust and sulfur remover produced by our factory has the following features: low operation cost, small equipment area, long service life, simple operation and less maintenance.

Application scope of boiler desulfurization tower

It has the characteristics of low resistance, low resistance and long service life.

Due to the chemical composition of coal, the flue gas of coal-fired boiler generates a large number of fine dust and sulfur-based gas after combustion. Sulfur reacts with moisture in the air to generate acid water gas, and then forms acid rain, which is discharged into the atmosphere, which has a serious impact on the environment.
