    What are the characteristics of flue gas desulfurization and dust removal?


    What is flue gas desulfurization dust collector? Flue gas desulfurization dust collector is a kind of desulfurization equipment that can be applied in large-scale industry.

    What is a flue gas desulfurization dust collector ? The flue gas desulfurization dust collector is a kind of desulfurization equipment that can be applied to large-scale industries. The flue gas desulfurization dust collector is used to desulfurize the flue gas containing sulfur discharged from the factory during the production process. A desulfurization device, a device with good desulfurization effect.

      How does the desulfurization deduster desulfurize the flue gas? The desulfurization deduster desulfurization methods are also different. One of them is to use a solid adsorbent to remove and remove sulfur dioxide contained in the flue gas during the operation of the desulfurization deduster. The fine limestone powder is sprayed into the furnace, and the limestone powder is heated to desorb sulfur dioxide contained in the flue gas, and the chemical reaction is used to achieve the desulfurization effect. The adsorbed and purified flue gas is discharged through the chimney.

      What are the types of desulfurization and dust collectors?

      The desulfurization and dust collector can be generally classified into three types: dry desulfurization, semi-dry desulfurization, and wet desulfurization according to the classification of equipment and adsorption raw materials.

      Characteristics of flue gas desulfurization dust collector

      1. Washing type working principle, high efficiency of dust removal and desulfurization, trapping many harmful gases.

      BYJ flue gas purifier integrates desulfurization and dust removal. It is a spray method with unique nozzle design. The glass fiber reinforced plastic spiral nozzle made by American technology sprays dense layers of water mist, dust and harmful gases and water mist under a certain water supply pressure. Full contact, so the effect of dust removal, desulfurization, nitrogen removal and carbon black washing is greatly improved compared with other wet dust collectors. The dust removal rate is ≥98%, the sulfur dioxide removal rate is ≥85%, and the Lingerman blackness of the flue gas is <1 level.

      2. The design of the dewatering plate is reasonable and unique, and the dewatering effect is good. There is a dewatering device in the cylinder. The design of the dewatering plate is reasonable and unique. When the mist passes through the dehydration device, it will be intercepted and changed by the collision. It will flow down the cylinder wall to prevent secondary water carryover and high dehydration efficiency.

      3. Low resistance, water saving, power saving, and low running cost.

      The flue gas is naturally introduced from the lower part of the cylinder, the cross section is large, and the wind speed is small, so the flue gas resistance is small, the main body resistance is ≤900Pa, and the system resistance is ≤1200Pa. Because the resistance is small, the power consumption is also small. In addition, the discharged water is precipitated and closed for recycling, on the one hand, it saves water resources, and on the other hand prevents sewage from flowing into the sewer, causing secondary pollution, achieving water and electricity saving effects, and reducing operating costs.

      4, small size, light weight, small footprint, convenient installation and transportation.

      The cylindrical body of this product is an integral structure. It comes with a stand when it leaves the factory. It is very convenient to install and move. It can be installed in various ways such as left and right hanging and overhead laying according to the size of the ground. It has strong adaptability.

      5. The operation is relatively simple and convenient, with very little maintenance, easy operation, management and maintenance, high operation rate, and adapt to various working environments.

      6. Strong adaptability to fluctuating SO2 concentration, different desulfurization processes can adapt to different sulfur content in coal; desulfurizers can be used in various forms such as lime, alkali, magnesium oxide, etc., which can achieve good desulfurization results.

      The working principle of flue gas desulfurization dust collector:

      The flue gas desulfurization and dust collector adopts the mechanism of cyclone centrifugal separation and DC centrifugal dehydration, and combines with impact foam condensation and chemical reaction to achieve the purpose of efficient smoke and dust removal and sulfur dioxide removal. The flue gas enters the outer cylinder in a tangential direction. Under the action of centrifugal force, the flue gas rotates downward along the cylinder wall. The inclined top plate of the outer cylinder has the function of pressing down the flue gas. Soot is wetted and condensed by it; dust particles settle down under the action of centrifugal force and liquid suction force, sulfur dioxide in the flue gas reacts with calcium hydride in the liquid as follows: SO2 + Ca (OH) 2 CaSO3 + H2O and To achieve the purpose of desulfurization, after the purified flue gas enters the inner cylinder, it passes through two dehydrators to form a rotating upward airflow, relying on the effect of centrifugal force to throw the carried water to the inner cylinder wall, and then descends to the conical sedimentation chamber The dehydrated purified flue gas is finally led out through the outlet pipe at the top of the dust collector.

      A chain plate type ash remover is installed at the lower part of the conical sedimentation chamber to continuously output the sediment. The liquid filling tube of the liquid level control box of the sedimentation chamber maintains the normal liquid level. During operation, quicklime (CaO) with a size of 50mm should be added to the dosing tank periodically to form Ca (OH) 2 to participate in the chemical reaction of desulfurization.
