Products overview:
Blast furnace smelting process in producing a large amount of dust containing CO and the high temperature gas, such as not governance recovery, not only environmental pollution, and waste of energy. Blast furnace gas management early mainly adopts washing tower, venturi and wet cleaning dust removal. But this method system equipment complex, water consumption and secondary pollution, washing equipment corrosion is serious, the gas in the disadvantages such as water cut, which hindered the wet cleaning process of the application.
TRGM type blast furnace gas and dry cleaning bag filter is my company with long bag low pressure pulse bag-type collector as the foundation, combined with the characteristics of blast furnace gas, the dust collector to take the pressure, ex-proof necessary safety measures, and the pulse soot cleaning air do necessary dehydration deoiling treatment, control technology used PLC microcomputer control, make its have higher dust removal efficiency, safety performance is good, operation and maintenance convenience, cover an area of an area small, etc, it is the first-selected products of the blast furnace gas dry.
Product features:
1, pressure circular cylinder body, can withstand the pressure of 0.1 MPa. Filter the upper set anti-explosion valve, ash bucket discharging device has a store ash bin, safety good seal performance,
2, equipment soot cleaning institutions (pulse valve, exhaust valve, back to the ash equipment, etc.) the use of PLC, with timing (constant resistance) and manual two kinds of control mode;
3, pulse soot cleaning, pressure gas using inert gas (nitrogen) or clean pressure gas;
4, the long bag low pressure pulse. Dust catcher compact structure, high strength, strong rigidity, good tightness, soot cleaning effect is good, the operation and maintenance is convenient, safe and reliable operation;
5, modular design, can be more unit combination use.
Blast furnace gas purification system:
1, technological process:
Blast furnace gas - inertia dust catcher, heat exchanger, TRGM blast furnace gas and dry cleaning bag filter - pressure regulating valve - gas tank, the user network
2, blast furnace gas and dry cleaning bag filter system each part features:
(1), gas pipeline: considering temperature change, pipeline are configuration bellows compensator, in order to offset the expansion and produce deformation.
(2), inertia dust: one is to remove large particles of dust, reduce dust concentration, protect the filter bag; The second is to reduce the gas temperature.
(3), heat exchanger: the indirect heating, when temperature is less than 100 °C, start heating system, prevent gas condensation.
(4), bag filter: using cylinder long bag low pressure pulse filter, the soot cleaning air for nitrogen, cylinder to pressure and seal.
(5), electrical control: control system with PLC as the core, including measurement instrument and central control two parts. Detection instrument main testing temperature and flow rate, pressure, CO content and parameters, and the signal is sent to the computer processing.
(6), the necessary valve: the valve has special heat-resistant pressure requirements.
(7), ash system: a scraper conveyor and dust humidifying unit into, the dust collector's collection of dust conveying to the truck inside.
