Product Description

Rising-tube ignition device

Innovative Technology: Develop a new electric‑heated igniter to enable automatic ignition of raw gas in the coke oven riser without opening the cover, thereby reducing manual intervention, minimizing environmental pollution and the occurrence of “blowout” phenomena, and resolving the issue of smoke emissions.

Key technologies: This igniter features a low failure rate and a long service life, operating at a safe 24 V supply voltage.

	Resistance wire	Ignition electrode	Electric heating ignition
Technical Principle	When current passes through the resistance wire, it glows red and generates heat, serving as an ignition source.	The mains voltage is stepped up to 7,000 V and transmitted via the ignition wire to the front end of the spark electrode, where it discharges. Energy is released directly without storage, resulting in a high firing frequency but very low spark energy.	The mains electricity is stepped up to 2,500 V by a transformer, then converted to direct current to charge the energy-storage capacitor. Once the capacitor is fully charged, the stored energy is discharged through a discharge tube, an inductor, and an ignition cable to the spark plug, releasing it in an instant.
Stain resistance	After repeated heating and cooling, the resistance wire loses its toughness and becomes prone to deformation and breakage.	The unipolar structure forms a discharge circuit with the earth, resulting in stringent environmental requirements and poor resistance to contamination; moreover, it exhibits unreliable ignition when exposed to moisture or carbonization.	A special ceramic material is positioned between the two electrodes. It delivers high spark energy and exhibits excellent self‑cleaning and stain‑resistance properties.
Power requirements	A separate power cabinet is required.	No separate power cabinet required.	No separate power cabinet required.
Service life	Three to six months	It gradually deforms during use; once the deformation exceeds the discharge gap, it must be replaced.	The igniter tip should be replaced at least once a year, though it can typically last up to three years.

When paired with a wireless temperature data logger, it allows remote display of measured temperatures and offers alarm and trend‑curve query functions. Via standard communication protocols, it seamlessly integrates with DCS and PLC systems. It features long‑life battery power, ultra‑low power consumption, a hermetically sealed metal housing, and robust networking capabilities.

Key technologies: Ultra-low-power wireless transmission technology, wide-range high-precision temperature measurement, and high-level protection design.

Measurement range: -200℃ to 500℃ (with thermistor or thermocouple options depending on the industrial control application), LCD display (optional), measurement accuracy: ±0.5%; power consumption: average operating current approximately 100 mA; explosion-proof rating: Exd IIC T4/T5/T6 Gb; protection rating: IP66.

Automated control

Innovative Technology: With system integration, intelligent control, and end-to-end service as its core innovation pillars, it enables the customized development of control strategies tailored to diverse process conditions, thereby achieving visibility, controllability, and optimization throughout the production process.

Key technologies: End-to-end automated integration technology and highly reliable electrical switchgear design.

Monotonous

Technological Innovation: A next-generation pressure stabilization system for coke oven carbonization chambers has been developed, ensuring stable pressure in each chamber throughout the coking process. This reduces pollutant emissions during coal charging and coking, enhances the environmental performance of coke ovens, improves the operating environment, increases the level of automation in coke oven operations, and extends the service life of the ovens.

Key technologies: A standard butterfly valve with an approximately equal-percentage flow‑control characteristic is ingeniously integrated above the water seal valve, enabling coordinated control to achieve time‑segmented, automated, and precise regulation of the pressure in a single‑chamber carbonization furnace.

Coking wastewater treatment

In response to the complex composition, high pollutant concentrations, recalcitrance, and high salinity of coking wastewater, a comprehensive treatment process combining biochemical treatment, membrane separation, and evaporation‑crystallization has been implemented to achieve true zero liquid discharge—enabling water reuse while recovering and valorizing sodium chloride and sodium sulfate from the salt fraction. The biochemical treatment employs an O‑A/O‑A/O process; membrane separation utilizes a UF‑RO1‑RO2 configuration for reclaimed water and a multi‑stage NF process for salt fractionation; and evaporation‑crystallization adopts triple‑effect evaporation coupled with cryogenic cooling and re‑crystallization for salt recovery. The biochemical system primarily removes the majority of COD, ammonia nitrogen, cyanide, and other pollutants, ensuring that effluent quality fully meets regulatory standards. The membrane separation stage focuses on water recovery, producing concentrated brine suitable for subsequent evaporation‑crystallization. Finally, the evaporation‑crystallization unit enables the resourceful utilization of sodium chloride and sodium sulfate while solidifying residual salts, thereby achieving true zero liquid discharge for coking wastewater. This integrated technology offers significant advantages, including stable operation, strong resistance to shock loads, high water‑recovery efficiency, consistent salt‑product quality, and genuine zero liquid discharge.

Flue gas desulfurization and denitrification

The flue gas desulfurization and denitrification system is a flue gas purification technology widely applied in the chemical industry to control the formation of nitrogen oxides and sulfur oxides. The system employs a self-developed low-temperature, sulfur‑resistant denitrification catalyst, enabling a sequential process of denitrification followed by desulfurization. While achieving ultra‑low emissions of nitrogen oxides, sulfur dioxide, and particulate matter, it also efficiently recovers waste heat from coke oven flue gas, maximizes steam production, and resolves the issue of excessive ammonia slip. In the desulfurization stage, a CFB fluidized‑bed process is utilized, with hydrated lime as the desulfurizing agent, effectively reducing operating costs. The system features a simple process flow, minimal water consumption, and eliminates the need for flue gas cooling or reheating. Equipment exhibits virtually no corrosion, scaling, or wastewater discharge; it occupies a small footprint, saving space, requires low capital investment, and incurs modest operating expenses. With its high adaptability, the system is suitable for diverse operating conditions and can be customized to optimize performance based on specific customer requirements, helping coking enterprises achieve ultra‑low emissions and green production.
