2. CHARACTERISTICS AND APPLICABLE SCOPE
2.1 General structure: According to the user's process and steam consumption requirements, this wastewater high-temperature incinerator system is composed of five parts: two incinerators, waste heat recovery boiler, high-temperature air preheater, and low-temperature air preheater.
2.2. Product model: DHS15-1.6-T
2.3. Product features: The product has a compact structure, micro-negative pressure operation, and the inner shield adopts a sealing and welding structure, which has good sealing performance, no environmental pollution, low system resistance (<1500Pa), high utilization rate, convenient operation, safe and reliable, boiler The use of bulk delivery can increase the center distance of the upper and lower drums, reduce the manufacturing cost of the boiler, and facilitate the construction, short installation cycle, low cost, and low capital investment.
2.3. Scope of application: The high-temperature flue gas generated by the waste water high-temperature incinerator generates steam through the flue-type waste heat boiler as its auxiliary energy for heat supply, gas supply, power supply and power, improve the overall utilization rate of heat energy, and reduce fuel consumption indicators. 1. Reduce power consumption to obtain economic benefits.
3. MAIN STRUCTURE OF THE SYSTEM
The front of the system is equipped with Φ4200 and Φ4800 incinerator devices, which integrate combustion, incineration, and efficient combustion support. The incinerator adopts a special upright structure, which burns all kinds of waste liquid, waste gas and waste water in the incinerator device. The high-temperature flue gas generated in the process enters the main body of the water-cooling system boiler and flushes the convection tube bundle; enters the high-temperature air preheater and flushes the high temperature The air preheater tube; enter the low temperature air preheater, flush the low temperature air preheater tube; enter the quenching tower to cool; enter the activated carbon injection system; and finally exhaust to the atmosphere through the induced draft fan and chimney.
Waste heat recovery boiler is a single drum horizontally arranged water tube boiler. The boiler body is composed of one boiler drum and one convection tube bundle, ascending and descending tubes, etc. The drum is equipped with continuous sewage, water supply device and steam-water separation device, etc.
