1.2 Main configuration technical parameters
(1) High-efficiency cooler
1) It has the function of rapid cooling treatment. It is required that the high temperature tail gas at 900℃ can be reduced to 2 in 2 seconds.
Below 50℃, it jumps over the temperature zone of secondary synthesis of dioxins and meets the operating temperature requirements of filter bags.
2) Material requirements: The manufacturing material of the shape main body is made of national standard 304 stainless steel with a thickness ≥ 2 mm..
3) The corresponding stainless steel covered electrode shall be used for the welding of the main body of the shape, and the welding shall be firm, with beautiful solder joints and no false welding or false welding.
(2) Primary Dust Collector (Mars Interceptor)
1) It can separate larger particles of dust, and has the function of eliminating Mars, and the interception rate of Mars is over 99%.
2) The shape shall be made of high-quality 304 stainless steel with a thickness ≥2mm, and the welding process shall meet the technical requirements.
(3) Pulse bag dust collector
1) Composition of bag dust catcher: box, bracket, maintenance frame, filter bag frame, filter bag, deflector, dust collecting room, pulse control instrument, etc. Shape main material: made of national standard 304 stainless steel, thickness ≥2mm.
2) The dust removal filter bag is made of PTFE coated filter bag, which can withstand the highest instantaneous temperature up to 260℃ and has a good dust removal effect. The warranty period of the filter bag is more than 3 years, and the specification is φ120×2000mm.
3) The speed of tail gas passing through the filter bag: about 0.8m/min.
4) The tail gas treatment capacity is 1500-6500m3/h..
5) The total filtration area shall not be less than 70㎡.
6) The dust removal efficiency is not less than 99.9%.
7) Set up an emergency bypass valve to prevent high temperature burning of filter bag.
8) Equipped with pulse controller: 20-way DC24V pulse solenoid valve.
9) The bag dust collector has feasible technical and technological measures to prevent condensation.
(4) Dioxin treatment device
(1) Using special activated carbon adsorption technology, the dioxin adsorption rate is over 80%.
(2) One-time filling of activated carbon with a service life of 200 cremated remains or more than 2 months.
(5) Smoke exhaust system
1) The induced draft fan shall adopt high-quality variable-frequency high-temperature resistant fan (each bidder shall indicate the brand, air volume and air pressure of the fan).
2) The induced draft fan is installed in a damping position, and the outlet is connected in a soft way to reduce vibration and noise.
3) The chimney is φ410mm in size, made of 304 stainless steel, with a thickness ≥2mm and a height of about 12m.
4) The chimney is provided with a detection sampling port;
(6) Connecting pipes
Connecting pipes shall be arranged reasonably according to the construction site to ensure no air leakage. All pipelines are made of 304 stainless steel with a thickness of ≥2mm, and all emergency pipeline valves must be high temperature resistant (not less than 300℃). )。
(7) Control system
