Anti-throwing fence is also called Steel Mesh Anti-Throwing Fence,Diamond Hole Anti-Throwing Fence,Viaduct Bridge Anti-Throwing Fence
Expanded mesh is a sheet of metal that has been cut and stretched into a regular pattern, usually a diamond shape. Due to its method of production, expanded metal is one of the most economical and strongest steel mesh or grating materials on the market. It can be used in many places, such as:
As an anti-throwing fence net used on roads, it also has the advantages of expanded metal mesh: affordable, beautiful design, safety guarantee, easy installation.

In 2002, the 3.5 million-ton/year catalytic cracking unit was completed and put into use. At that time, the catalytic unit slurry filtration system built with the unit had not been opened for various reasons. In recent years, the 3.5 million tons/year catalytic cracking unit has many varieties of raw materials for processing, and the quality is poor. As a result, the yield of catalytic sloshing oil slurry continues to rise. The amount of mud slaughtered by the equipment is now 40 tons/hour, which is more than double that of the past. . In this case, the solution to the problem of throwing slurries out of the slurry becomes even more urgent. At the same time, the demand for fuel has increased significantly after the new 6 units of Dalian Petrochemical have been put into operation. If the catalytic slurry can be used for filtration, a large amount of liquefied gas will be saved, resulting in significant economic benefits.
There are generally two approaches to catalyzing slugs out of slurries. One is to take away ordinary residual oil, and the other is to use fuel as a fuel. Considering the economic aspect and the development of the company, catalytic slug oil slurry is the best fuel for the device, but the furnace cannot directly use the catalytic oil slurry, and the catalyst particles in the slurry will bring safety hazards to the normal operation of the heating furnace. For example, the catalyst particles contained in the slurry will cause the nozzles of the heating furnace to wear and clog, which will seriously affect the long-term operation of the heating furnace; the catalyst particles contained in the flue gas of the oil slurry will be deposited on the surface of the furnace tube, affecting the heat transfer effect. Therefore, the catalytic oil slurry can only be applied after filtration and purification. However, in the past, in the practice of catalytic oil slurry filtration, some technical problems were not satisfactory. Therefore, breaking the "bottleneck" of catalytic oil slurry filtration has become a prominent problem that the entire industry urgently needs to solve in recent years.
In November 2007, the five joint workshops began the manual commissioning of the slurry filter. The workshop changed the operating conditions of the slurry filter several times to overcome the unfavorable factors affecting the operation of the slurry filter, completed the predetermined test program, and successfully performed the manual operation, which laid the foundation for the next automatic operation. During this period, the technical office and the workshop repeatedly explored the automatic operation method and used the equipment stoppage inspection opportunity in April this year to transform the system. Since the information available on hand is very limited, many practical problems must be solved by themselves and solutions must be found through trial and error. During the test, Wang Jian, the director of the device, and Xie Shengli, the plant technician, performed on-site monitoring of the system operation at the time of 24 o'clock. Wu Yu, the technical director, often went deep into the site to instruct and study and formulate measures to solve the problem. They played an important role in the successful use of the system. On June 16 of this year, the automatic operation system for slurry oil filtration entered the preparation phase for commencement of construction. On June 25, the slurry automatic filtration system was automatically operated for investment.

Oil slurry automatic filtration system successfully operated in Dalian Petrochemical
The automatic filtration of slurry in catalytic devices has always been a problem in the industry. Recently, this dilemma was initially resolved at Dalian Petrochemical. On June 25th, the automatic slurry filtration system was successfully operated in the 3.5 million tons/year catalytic cracking unit of the company's five joint workshops. At present, the technical departments and workshops are paying close attention to the operation of the system and accumulate experience to further improve the effectiveness of the oil slurry filtration system and the promotion and application of automatic slurry filtration technology.
