Zhongyuan Dahua Urea Cooling Absorber Initially Meets Green Production Standard

Drying equipment

On June 16, the environmental protection monitoring data of the Zhonghua Dahua urea plant showed that the ammonia content was only 2% when the amount of low-pressure venting increased, and it initially reached the green production standard for energy conservation and environmental protection.

It is understood that the company's independent design, independent processing and production, independent installation of urea plant low-pressure air recovery system with a new type of cooling absorber, is the company's technical personnel using waste equipment and new technology for a "green transformation." The investment of less than 100,000 yuan has completely solved the "disease" that the ammonia emission of the low-pressure venting system exceeded the standard. The introduction of the new cooling absorber not only enhanced the scrubbing absorption effect of the low-pressure vent recovery system, but also reduced the ammonia content in the tail gas from 90% of the original maximum to 2% or less. The hourly ammonia loss was reduced from 100 kg to 1 kg, and Reduced steam consumption, reduced urea production costs, one year for the company to increase economic benefits more than 1.7 million yuan.

Wire Rope

Tower Crane wire rope is usually used on the tower crane hoisting mechanism, trolleying (luffing) mechanism and slewing mechanism. BQ could provide all models of Wire Rope for Tower Crane. The diameter of tower crane steel wire rope could be 12mm, 14mm, 16mm, 18mm, 20mm, 22mm. 16mm Wire Rope could be used for 12-14 ton Tower Crane. 18mm Steel Wire Rope could be used for 16ton tower crane. Tower crane wire rope could be galvanized wire rope, Non-Rotating Wire Rope, bright wire rope, stainless steel wire rope. Wire Rope Wedge is used for fixing or connecting the wire rope of tower crane.


Wire rope is an essential component of tower cranes as it provides the necessary strength and flexibility to lift heavy loads. Tower cranes typically use high-strength steel wire ropes that are specifically designed for heavy-duty lifting applications.

The wire rope used in tower cranes is typically made up of multiple strands of steel wires twisted together to form a strong and durable rope. The number of strands and wires in the rope can vary depending on the specific requirements of the crane.

Tower crane wire ropes are designed to withstand high loads and provide excellent resistance to abrasion, fatigue, and corrosion. They are also engineered to have a high breaking strength to ensure safety during lifting operations.

Regular inspection and maintenance of the wire rope is crucial to ensure its safe and efficient operation. This includes checking for signs of wear, corrosion, or damage, as well as lubricating the rope to reduce friction and prolong its lifespan.

Overall, wire rope is a critical component of tower cranes, providing the necessary strength and reliability to handle heavy lifting tasks in construction and other industries.
