Waterproof Coil Industry Governance Technology Route
(1)Exhaust Gas Pre-treatment
- Asphalt flue gas is filtered and deoiled at 4 levels before entering RTO, with an oil-gas separation efficiency of up to 90%
Wire mesh filter for exhaust gas from batching tank
Cyclone separator
Tower filter
RTO
(2)Exhaust Gas Collection
(3)Exhaust Gas Collection & Low-point Oil Discharge
- The inclination angle of the pipeline is convenient for collecting the liquid in the pipeline; a drain port is set at the low point.
(4) Exhaust Gas Pipeline Maintenance Platform
(5) RTO Oil Discharge Structure Design
The furnace bottom plate is completely drained
Completely drain the valve frame
Complete drainage of manhole doors
Furnace bottom oil drain design
- The bottom of the rotary valve RTO furnace body is 2 meters above the ground. An oil drainage structure is designed inside the furnace body, which is more conducive to oil drainage than the bed-type RTO, so that no oil is stored in the furnace body, eliminating the safety hazard of fire caused by oil accumulation at the bottom of the bed-type RTO during back-baking.
(6) Energy-saving Advantages of Rotary Valve RTO
Three-bed RTO | Our rotary RTO | Comparative analysis | |
Exhaust gas conditions | 1 meter tire line 1 | 1 meter tire line 1 | Same working conditions |
RTO outlet flue gas temperature | 8 batching kettles | 8 batching kettles | |
Chimney outlet temperature | 95℃ | 75℃ | -20℃ |
Gas consumption statistics | 68℃ | 49.3℃ | -18.7℃ |
Measurement conclusions | 30m³/h | 20m³/h | -10m³/h |
- Test conclusion: Our rotary valve RTO has a chimney temperature 18.7℃ lower than that of a three-bed RTO, saving 10m³ of natural gas per hour;
- For every 1°C increase in chimney exhaust temperature, the gas consumption increases by at least 1m³ per hour.
Classic Cases in the Waterproof Coil Industry
Hongyuan Waterproof Technology Group Co., Ltd.
Founded in 1996, it has developed into a professional waterproofing system supplier integrating scientific research and development, production, sales and construction services, a “prefabricated construction industry base” and a “leading enterprise in China’s waterproofing industry”.
At present, the company has 5 waterproof production bases with 62 modern waterproof material production lines, with an annual production capacity of waterproofing membranes of 290 million square meters and an annual production capacity of coatings of 290,000 tons. The SBS two-meter production line and the large-scale EPDM vulcanization production line were both born in Hongyuan. The company’s products cover waterproof fields such as railways, roads and bridges, municipal administration, civil construction, industry, and military industry, with 8 series and more than 100 varieties, covering most functional requirements.
Hongyuan Waterproofing took the lead in using 2 sets of 3-bed RTO in 2018 and 2019. In 2021, the third-generation technology rotary valve-type RTO was selected for the environmental protection equipment upgrade and reconstruction project of 3 production lines in the east factory area and 2 production lines in the west factory area, and was used in benchmarking , the rotating RTO has significant energy-saving effect and makes equipment maintenance more convenient.
When the 50,000 m3/h air volume rotary valve type RTO handles the exhaust gas of a coiled material production line, the average air volume is 20~23 m3/h, and the 35,000 m3/h air volume three-bed RTO uses 31~34 m3/h of the same air volume when processing a coiled material production line. cubic meters/hour of natural gas.
Anhui Wuhu Production Base
When the 35000m3/h air volume rotary valve RTO treats the exhaust gas from two asphalt coil production lines and the corresponding batching kettles, the average gas consumption is 21 cubic meters/hour.
Pollutants | Target emission limit (mg/m³) | Actual emission value (mg/m³) |
VOCs (non-methane hydrocarbons) | ≤10 | 1.44 |
Particulate matter | ≤10 | 8.7 |
Benzopyrene | ≤0.1×10﹣³ | Below the detection limit (minimum value) |
Asphalt fume | ≤10 | 9.2 |
Weinan Keshun Production Base
The total investment of Weinan Keshun Production Base is 596 million yuan, covering an area of 147 acres. It produces 5 million square meters of polymer waterproofing membranes, 40 million square meters of modified asphalt waterproofing membranes, 20,000 tons of waterproof coatings, and 100,000 tons of special mortars per year.
The project is equipped with 2 rotary valve RTOs with a wind volume of 45,000 and waste gas pre-treatment equipment to treat the waste gas generated during the production process and monitor online to ensure stable and standard emissions.
