2) Technical performance:
The serial number item refers to the technical parameters (performance) index of the equipment.
1. the external dimensions of the equipment are l× w× h = 12.5m× 2.2m× 3.5m (2%).
The whole structure is made of high-quality stainless steel, which is not less than 2mm. The weld seam is uniform, firm and beautiful.
2 The overall configuration process is equipped with cremation machine, cyclone dust removal, air cooling, deacidification and desulfurization, bag dust removal, activated carbon adsorption and chimney.
The cyclone dust removal system has the functions of first-class flue gas purification and cooling treatment, which can separate large particle dust with high temperature and prevent it from entering the bag dust removal system and burning the bag;
The air-cooled cooling system has the function of secondary cooling treatment. The radiating plate radiator made of high-quality national standard profiles and plates is ventilated and cooled by an industrial (axial flow) fan, which can reduce the tail gas from 900℃ to below 260℃ in two seconds, jump over the temperature zone where dioxins are easy to form, and meet the requirements of filter bag dust removal temperature. ※. Power of cooling axial fan: 0.85KW, 2 sets in number.
5. The deacidification and desulfurization system adopts automatic feeding device (motor power is 0.75KW), and the feed rate can be adjusted. The purification treatment rate of harmful pollutants such as acid and sulfur reaches over 98%, and the discharge standard meets the national standard requirements of GB13801-2015.
6. Overall dimensions of bag dust suppression system: L*W*H =3800*2200mm*3500mm; The dust removal filter belt is made of high-quality coated glass fiber needled felt and fiber fabric filter material, which can withstand the temperature of 260℃, totaling 160 pieces, with good dust removal effect and long service life. Dioxin treatment capacity: meet the requirements of GB13801-2015 national standard.
7. On-line pulse cleaning device adopts 7.5KW high-quality air compressor and matching pulse cleaning device (power: 1.05KW), which can clean the filter bag regularly and quantitatively.
The activated carbon adsorption system uses the adsorption function of activated carbon to eliminate the odor in the flue gas, and re-purify the filtered flue gas to reduce the harm to human body.
9. The ventilation and smoke exhaust system adopts high-quality domestic high-temperature variable frequency induced draft fan, with shock absorption and positioning, and the air outlet adopts rubber telescopic flange connecting sleeve.
The control system has automatic and manual operation modes, which can be switched freely without interference. When the tail gas treatment equipment is stopped, the flue gas can be switched to the chimney of the cremator for discharge with one key.
Adopt domestic well-known brand electrical components and domestic high-quality multi-strand copper core cables. Adopt internationally accepted plug-in installation.
Note: The service life of tail gas treatment equipment is not less than 20 years.
