Brief introduction of environmental protection management project of Wenzhou Likeda Printing Co., Ltd

Exhaust gas source: organized exhaust from the oven of 8 tipping paper printing machines; 8 tipping paper printers unorganized, 3 gravure printers organized + unorganized waste gas and environmental wind in ink room and hazardous waste room

Design air volume: total air volume of organized waste gas: 9200m ³/ h

Unorganized waste gas + organized total air volume of gravure printing machine: 192000 M ³/ h

3000mg/m³~5000mg/m³

Waste gas concentration: Organized: 3000mg/m ³~ 5000mg/m ³

300mg/m³~600mg/m³

Unorganized: 300mg/m ³~ 600mg/m ³

Waste gas components: ethanol, ethyl acetate, n-propyl ester, etc

Process scheme: LEL air reduction and thickening transformation + rotary valve regenerative thermal oxidizer (RTO) + unorganized partition Collection + zeolite concentration runner + regenerative rotary valve oxidation furnace (RTO) + steam waste heat recovery system

RTO model selection: 2 sets of 100000m ³/ H zeolite concentration rotor +2 sets 70000 M ³/ H rotary valve regenerative thermal oxidizer (RTO) + 1 set of 1.5T steam waste heat recovery system (shared)

Two of them are 70000 m³/h regenerative rotary valve oxidation furnace (RTO) can provide high-temperature flue gas for steam waste heat boiler. At the same time, two 70000 m³/h rotary valve regenerative thermal oxidizer (RTO) can provide desorption heat for zeolite concentration rotor.
