Performance advantages and technical introduction of dust collector and desulfurizer
1. Introduction to dust collector and desulfurizer technology
The type dust collector and desulfurizer integrates desulfurization and dust removal. It adopts the working principle of inertial collision. The air flow is under the action of negative pressure of the induced draft fan. Impacting the liquid surface at high speed, a large amount of foam and droplets are splashed, and larger particles fall into the water. The airflow continues to rise sharply under the action of the deflector. Under the action of inertial collision, most of the dust and water form water. The ash mixture is brought out. The application of this working principle solves the problem of greatly reducing the dust collection and desulfurization efficiency due to clogging of the spray nozzle during use of the spray dust collector and desulfurizer.
Efficient and thorough secondary dust removal and desulfurization
The Type series dust removal and desulfurizer is equipped with a fixed impeller on the upper part. The inclination angle of the upper blade of the impeller is used to further collide and condense the rising air flow with the liquid droplets. A water-cement mixture is formed, which falls into the water under the action of gravity, thereby achieving the effect of dust removal and desulfurization. After two dust removal and desulfurization, the dust removal efficiency can be as high as % or more, and the desulfurization efficiency can be as high as % or more.
, Scientific and unique impeller dehydrator, saving energy and reducing consumption, using the principle of centrifugal force to dehydrate
After secondary dust removal and desulfurization, the air flow forms a cyclone under the action of the impeller blades, and the water and gas are separated under the action of centrifugal force , the purified flue gas is discharged into the atmosphere through the induced draft fan.
2. Technical key and performance
High temperature resistance
The main body of the series of fiberglass dust collector and desulfurizers is made of modified high-temperature resistant and high-performance resin-based composite materials. Ordinary resin composite products have poor temperature resistance and are not suitable as the main material of dust collectors. The high-temperature-resistant modified resin-based composite material developed by our company is the first of its kind in China.
, resistant to acid and alkali corrosion, anti-aging, light weight and high strength, long service life
Due to the use of resin composite material, a widely used corrosion-resistant material, and its high temperature resistance modification, In addition, the main body of the dust collector is formed in one step using large-scale winding equipment, which greatly increases the strength of the equipment. The dust collector desulfurizer of the model series has high strength, corrosion resistance and other properties, and the maintenance rate is almost zero under normal and standardized operations. The decay coefficient of polyester is generally years. The FRP dust collector and desulfurizer developed by our company is an organic combination of other high-temperature resistant materials, and comprehensively considers other properties of the dust collector. In addition to high temperature resistance and corrosion resistance, the FRP dust collector has the characteristics of high temperature resistance and corrosion resistance. In addition, a wear-resistant layer is added to the equipment inlet, which greatly extends the service life of the dust collector.
The structure adopts split-combined type, which facilitates transportation and installation
The dust collector and desulfurizer has a scientific and reasonable split-type design in structure. This novel and exquisite structure facilitates transportation and installation for users. Saves manpower, material resources and daily maintenance.
, Scientific and unique impeller dehydrator, which saves energy and reduces consumption. It uses the principle of centrifugal force to dehydrate. The impeller dehydration equipment does not require power energy and has no moving parts in the equipment, thereby improving operational reliability and stability and reducing losses. , reduce maintenance costs.
The specific area of liquid-gas contact in the diffusion chamber of the equipment is large, and the dust removal and desulfurization efficiency is high. Experiments have proven that the liquid-gas ratio and desulfurization efficiency can reach more than %.
The equipment uses working principles such as inertia and impact, which saves water pumps and reduces operating costs compared with other dust collectors.
The equipment is integrated with dust removal and desulfurization, and consumes little water. It can use sodium hydroxide, industrial alkaline wastewater or slag water, and boiler blowdown wastewater as desulfurizers, which not only saves energy, but also eliminates secondary pollution.
3. Comparison of the technical level of similar products
Acid and alkali resistance, corrosion resistance, high temperature resistance, anti-aging, low operating cost, small equipment footprint, long service life, easy operation, and low maintenance.
Generally, the exhaust smoke from coal-fired industrial boilers contains a lot of harmful gases such as sulfides and nitrogen oxides. When combined with water, it forms a highly corrosive acidic liquid, which has a strong corrosive ability to metal parts and is not harmful to granite. The calcium, magnesium, iron and other components contained in the stone will also gradually cause chemical reactions, gradually corroding the inside of the granite, destroying the structure of the granite, and causing it to erode and peel off layer by layer. Due to the high-speed flue gas erosion, ditches or pockmarks are formed, which are uneven and cannot form a water film, which affects the dust removal effect and increases the difficulty of maintenance, thus reducing the service life of the dust collector. The metal dust collector is composed of iron plate or stainless steel plate, lined with cast stone, and acid-resistant clay for anti-corrosion. However, the expansion coefficients of the two are different after heating, and the bonding is not strong. The cast stone is easy to break and fall off when exposed to water at high temperatures, thus reducing the service life of the equipment. .
