product description
The F-TL type desulfurization pump is a new generation of high-efficiency series desulfurization pump based on the experience of the successful design and manufacture of ZM series slurry pumps, according to the characteristics of my country's flue gas desulfurization pump, absorbing the advanced technology of similar products at home and abroad, and carefully developed. The maximum flow range of the pump can reach mm³/h, the pump head is generally below 100m, covering all desulfurization system pump working conditions, can be used as absorption tower large slurry circulation pump and limestone slurry delivery pump, gypsum slurry discharge pump, recovery Pumps, pit pumps, etc.

Performance and material characteristics
&#;Hydraulic design adopts computer CAD-aided design and two-phase flow theory design.
With competitive price and timely delivery, SUNBO PUMP sincerely hope to be your supplier and partner.
&#;High pump efficiency, long service life and reliable operation.
&#;Overflow parts are made of all-metal abrasion-resistant chromium-nickel alloy material. Both abrasion resistance and corrosion resistance are considered. The surface intergranular gap is small.
&#;High reliability of operation, the all-metal pump overcomes the shortcomings of non-metallic pump lining, such as falling off, tearing and deformation.
&#; Small hydraulic friction loss, more than 3% higher efficiency than non-metallic pumps with the same parameters.
&#;The size of all metal pumps is easy to control and ensure, the surface finish of parts is high, the clearance of parts is small, the volumetric efficiency is high, and the overall efficiency is more than 5% higher than that of non-metallic pumps.
&#;Over-current components have a long service life, and the metal shielding plate is more resistant to shear sliding wear than ordinary non-metallic materials, and can withstand long-term shear wear.
&#;Dynamic abrasion resistance is 0.008&#;0.08mm years, high tensile strength, can maintain constant performance under long-term abrasion conditions.
Shaft seal type
The shaft seals all use mechanical seals. Our company's equipped mechanical seals are divided into two types: water seal type and water seal type.
&#;With shaft seal water type
Combined mechanical seal, the shaft seal water flow is 0.1 to 1% of the pump flow, but the minimum is not less than 1m3/h; the shaft seal water pressure is equal to 1/2 of the pump outlet pressure.
&#;Waterless without shaft seal
Non-aqueous medium self-washing mechanical seal, unique structure, good water saving effect.

Wet flue gas desulfurization, flue gas through the absorbent contained in the aqueous solution of the reaction, the absorbent can use ammonia or sodium sulfite and other materials. But the more widely used is the use of lime or limestone slurry as absorbent. The use of lime or limestone slurry, so that the tail of the boiler flue gas in the spray tower with the contact reaction, the slurry of calcium in the flue gas with the reaction of SO2 to generate gypsum, while removing other pollutants in the flue gas, such as dust, HF , SO3 and the like. To this end, the tower should be installed outside the large-scale circulating pump, circulating to the tower supply limestone slurry. In addition, some auxiliary pumps are also required, such as pre-wash pumps for lime slurry systems and pumps for gypsum drainage.
Limestone slurry contains chloride ions ( ~ ) X10-6, pH 4.5 ~ 7 between the concentration of 20% to 35%, up to 60%. Desulfurization pump over-current components must be selected with anti-wear and corrosion resistance of the material, a rubber lining, lining ceramic, all-metal alloy and other materials.
generally used cantilever single-stage , the specific speed is generally 250 ~ 350. Impeller can be designed in accordance with the general method of centrifugal pump, closed impeller, open impeller and so on. Taking into account the need for a long continuous power plant running time, so the cavitation and efficiency of the pump have some requirements.
Usually with a back blade, reducing the pressure of the sealed chamber, reducing wear and tear.
Adjustable axial position can be adjusted by adjusting the bearing seat, which can adjust the increased clearance due to wear and reduce leakage gap to ensure that the pump in high-efficiency operation. Or provision of replaceable wear plates.
Shaft seal with a variety of forms, packing seal, mechanical seal, vice impeller seal. General optional cartridge mechanical seal, high precision, easy replacement and maintenance, reliability is also high.
Bearing according to the different load with different forms, light load pump shell with a pair of angular contact ball bearings + cylindrical roller bearings, heavy duty pump tapered roller bearings + cylindrical roller bearings. Lubrication with a thin oil bath lubrication.
Thermal power plant combustion emissions contain a large number of harmful substances, emissions to the atmosphere will cause serious pollution to the environment. FGD-Flue Gas Desulphurization, is to remove SO2 from the flue gas.Flue gas desulfurization equipment can be the vast majority of sulfide from the power plant flue gas in order to achieve emission standards to protect the environment. At present, large-scale thermal power plants use more mature wet process for flue gas desulfurization.Wet flue gas desulfurization, flue gas through the absorbent contained in the aqueous solution of the reaction, the absorbent can use ammonia or sodium sulfite and other materials.
