In mid-May, experts from the China Petroleum and Chemical Industry Federation and the Chinese Society of Environmental Sciences conducted a scientific and technological evaluation of the clean production process of the sulfur-iron-titanium co-production process titanium dioxide developed by Henan Lilien Chemical Co., Ltd. Zhang Jian, an academician of the Chinese Academy of Engineering, and other experts all agreed that the technology has opened up a new path for China's sulfuric acid titanium dioxide industry to crack down on environmental predicament and achieve healthy industrial development.
The experts in the appraisal group evaluated and evaluated the company. It is the first company in China that has successfully developed the clean production technology of the sulfur-iron-titanium co-production method titanium dioxide. The technology is mature, with unique environmental protection superiority and leading technology, reaching international advanced Level. It is understood that the technical characteristics of this technology are the joint production of sulphuric acid titanium dioxide and sulphuric acid, iron pigment production, ferrous sulfate monohydrate preparation, antimony oxide extraction, titanium gypsum products and other devices. In the industrial chain, the “three wastes†discharged from the original sulfuric acid process titanium dioxide were treated as “waste and treasureâ€. This technology not only systematically and comprehensively transforms the original titanium dioxide production process, but also realizes integrated innovation of various product production technologies. This technology has increased the utilization rate of titanium resources of the enterprise from 82% to 87%; the thermal energy utilization rate of the acid system has been increased from 65% to over 90%; the total energy consumption of the enterprise has dropped by 40%, and the annual energy saving is 5 10,000 tons of standard coal; corporate water consumption decreased by 35%; annual use of 104.000 tons of waste slag, to solve the problem of waste residue, calcium carbide mud in the plant; enterprise product quality from the original single titanium dioxide increased to more than 10 kinds of products.
According to reports, in late April, the China Petroleum and Chemical Industry Federation and the Environmental Society organized experts and went to Henan Yililian Chemical Co., Ltd. to carry out an on-site assessment of the clean production technology of the sulfur-titanium co-produced titanium dioxide powder for the appraisal meeting. Submitted the assessment data report.
It is also known that China is the second largest producer of titanium dioxide in the world after the United States, but the vast majority of production uses the sulfuric acid process, which has the problem of large emissions of “three wastes†and frequent environmental pollution accidents. Experts at the meeting pointed out that due to technical constraints, domestic titanium resources, quality restrictions, market demand and many other factors, the current domestic sulfuric acid method titanium dioxide can not be completely eliminated. How to make use of the existing sulfuric acid process titanium dioxide industrial base and carry out clean production technology innovation is the top priority for the Chinese titanium dioxide industry. Therefore, the successful development of this technology is of great significance to solving the environmental protection and development issues of China's sulfuric acid titanium dioxide industry.
Tower Crane cabin is the control center of the crane and is attached to the slewing unit. In order to get to the tower crane cab, the operator must climb a series of ladders within the mast.
The movement of the tower crane is controlled from the operator's cabin. Within the tower crane cabin, you'll find the operator's chair with joystick controller, electronic monitoring devices, and communication systems. Many cabins come with climate control to ensure a comfortable work environment. The Operator Cabin for Tower Crane is part of the slewing assembly.
A cabin for a tower crane is a small enclosed space located at the top of the tower crane Mast Section or tower crane jib. It is where the crane operator sits and controls the crane's movements and operations. The tower crane cabin is typically made of steel or aluminum and is designed to provide a safe and comfortable working environment for the operator. It is equipped with controls, instruments, and communication systems that allow the operator to maneuver the crane, lift and lower loads, and communicate with other personnel on the construction site. The cabin is often equipped with heating and air conditioning systems to ensure the operator's comfort in various weather conditions. Safety features such as guardrails, harness attachment points, and emergency controls are also included in the cabin design to protect the operator in case of accidents or emergencies.
