Shanxi Chenggong Solid Waste

Shanxi Chenggong Solid Waste Comprehensive Disposal and Utilization Co., Ltd. plans to build a 100t/d hazardous waste incineration disposal system for the treatment of hazardous solid waste and waste liquid generated in Xingxian County and surrounding areas.

According to statistical classification, the hazardous waste to be processed in this project includes solid, semi-solid, and liquid forms. The main categories involved in the list of hazardous waste are HW02、HW03、HW04、HW05、HW06、HW07、HW08、HW09、HW11、HW12、HW13、HW14、HW016、HW37、HW38、7HW39、 HW40、HW45、HW49 Wait.

According to the above statistics, the annual total amount of semi-solid and liquid waste processed by this incineration system is about 30000 tons/year (solid-liquid ratio: solid semi-solid~80%, liquid~20%), converted into an hourly processing capacity of 4.17 tons/hour; The annual working time is 300 days, which means the annual operating time is 7200 hours per year; The average calorific value of incineration design is 3500kcal/kg.

 

The main components of this project are:

(1) Waste liquid storage and feeding system: Provide daily waste liquid storage tanks, conveying and feeding systems (including daily waste liquid storage tanks, waste liquid pumps and spraying systems);

(2) Solid waste pretreatment and feeding system: crushing, crane, grab bucket, weighing, conveyor, feeding seal, etc;

(3) Solid waste feeding system: providing phosphorus plate feeder, double flap door, chute, pushing mechanism, kiln head bucket waste elevator, etc;

(4) Incineration system: providing rotary kiln, secondary combustion chamber, burner, combustion fan, and slag discharge system;

(5) Waste heat utilization system: providing waste heat boilers and supporting automated soft water systems, soft water tanks, deaerators, deaeration water pumps, feedwater pumps, electrical control systems, air separation cylinders, etc;

(6) Flue gas treatment system: providing rapid cooling, dry deacidification, bag dust removal, wet deacidification, wet electrostatic precipitator, flue gas heating, etc;

(7) Smoke and air system: providing blowers, induced draft fans, chimneys, etc;

(8) Electrical control system: Provide electrical system and instrument self-control system (using DCS). The control system reserves communication interfaces for access to the entire factory production management system;

(9) Reserve monitoring and communication interfaces within the incineration boundary;

(10) Pipe gallery, bridge frame, operating platform, ladder, lifting equipment (crusher maintenance, urea lifting, sodium bicarbonate, activated carbon lifting, etc.);

(13) Installation materials, spare parts, and specialized tools.

(14) Design reserved space for SCR device.
