Selection and Maintenance of Bag Type Dust Collector

With the increasing attention of the whole society to environmental protection and energy saving, how to improve the efficiency of dust control in cement production has become a consensus. This paper analyzes the working principle, selection method, factors affecting dust collection efficiency and improvement measures to improve dust collection efficiency, and puts forward the methods of use, maintenance and maintenance. 1 Structure and working principle The main components of the 1.1 (1) Box: mainly fixed filter bags and air circuit components, made into a fully enclosed form. When cleaning ash, compressed gas first enters the box and flushes into the inside of each filter bag. According to different specifications, the box is divided

Bucket elevator structure and characteristics of the advantages

Bucket elevator has the advantages of high conveying efficiency, high lifting height, stable and reliable operation and long service life. The casing is transverse and small in size, and occupies a small space. The lifting height can reach 60-100m and the system has good reliability and few failures. It can realize remote display and control. In addition, it has good sealing performance and can prevent dust pollution and dust explosion. Compared with other vertical conveying equipment, power consumption is small pneumatic conveying 1/3. With the vigorous development of the construction of the four modernizations, the application of bucket elevator is more and more extensive, and has become an indispensable equipment in modern continuous conveying, suitable for conveying powder, granular and small

Solve the phenomenon of belt slippage of belt conveyor

Belt conveyor is a kind of friction drive to transport materials in a continuous way of machinery, not only for the transport of broken materials, can also be carried out into pieces of goods, but also with the industrial enterprises in the production process of the process requirements, the formation of a rhythmic flow transport line, widely used in a variety of modern industrial enterprises. In the process of use, the phenomenon of belt slippage sometimes occurs. The solution is as follows: the belt conveyor using the heavy hammer tensioning device can add a counterweight to solve the problem when the belt slips, until the belt does not slip. But should not add too much, so as not to make the belt bear unnecessary excessive tension

Technical specification for safety operation of bulk cement truck

1. Before loading, check and remove the ash and slagging in the tank and discharge pipeline. All pipelines and valves shall be opened and closed flexibly without blockage and air leakage. All connecting parts shall be firm and reliable before loading. 2. Before opening the loading port, the exhaust valve should be opened to eliminate the residual air pressure in the tank. 3. When loading, the switch of the material detector in the material tank should be turned on. When the material detector sends out a full-position sound call signal, the loading should be stopped immediately. 4. After loading, clean the cement accumulated on the edge of the loading port, cover the feed port cover, and insert the bolt and lock it. 5. Before unloading, the vehicle should be parked in

Analysis on the Development Trend of China's Valve Standards

(1) Strengthen the connection between standards and scientific research, especially the research of major national scientific and technological projects, guide key enterprises with advanced scientific research and technology, transform the achievements of independent innovation into standards, and promote the development of new technologies and new processes. The National Valve Standard Committee is now developing the national standard "intelligent valve electric device". Valve intelligent electric device, is a new product developed at the beginning of this century abroad, China through the introduction and research and development, has mastered the technology, and the development is very fast. Yangzhou Electric Power Building, Tianjin Ertong, Wenzhou Rotok, Changzhou Power Station Auxiliary Equipment, etc. can be produced, and the product quality is also quite good. Development of high technology-inclusive

Application of glass fiber coated filter bag in kiln head dust collector

Shanghai Pudong Cement Plant has built the first domestic self-designed and manufactured dry pre-decomposition production line. The first one has adopted an electric bag composite dust collector in the kiln head, and pioneered the use of glass fiber coated filter bags in the system. Since the dust collector has been in operation for more than 3 years, the filter bag has zero damage and the resistance is controlled at 700Pa ~ 950Pa, which has achieved great success and filled the gap in the use of glass fiber coated filter bag in the kiln head dust collector. Now the application of glass fiber coated filter bag in Pudong cement plant is introduced to you, so that readers can get some experience and methods suitable for their own transformation. The production line of Shanghai Pudong Cement Plant is made by Tianjin Cement Industry

China's cement industry will usher in ten thousand tons of production line kiln head "bag dust collection" era

With the implementation of the kiln head bag dust collector and air cooler project of Xuzhou Zhonglian Cement Phase II 10000t/d clinker cement production line successfully won by China Building Materials (Beijing) Environmental Protection Engineering Development Co., Ltd., China's cement industry will usher in the era of "bag dust collection" at the kiln head of 10,000-ton clinker production line. It is reported that this is currently the largest single kiln head bag dust collector in China, and it is also the first time that the kiln head of the domestic 10,000-ton clinker production line adopts the method of "air cooler and cloth bag dust collector" for dust collection. This will change the previous 10,000-ton clinker production line kiln head has been using electric dust collector dust collection method, marking China's environmental protection in the field of cement.

Technical Status and Prospect of Bag Filter

Preface China's energy structure is dominated by coal, China is the world's largest coal consumer, every year there are a large number of soot emissions, serious environmental pollution. Therefore, environmental protection requirements are becoming more and more stringent, and the state has put forward more stringent requirements for soot and S02 emissions. The Emission Standard of Air Pollutants for Thermal Power Plants (GB13223-2003) stipulates that since January 1, 2004, the maximum allowable mass concentration of soot emission is 50mg/m3 for new, expanded and rebuilt thermal power plant construction projects approved by the environmental impact report of the construction project. For the new standard, the current use of electrostatic precipitators

Introduction and advantages and disadvantages of bag filter

Bag filter in China's various industrial production departments have a history, and now the bag filter has become a common dust collector for dust removal in most factories. The production of dust collectors is mainly due to the progress of scientific and technological development and the social demand for dust collectors. As a kind of equipment for filtering the exhaust gas discharged from industrial production, the dust collector has been widely used because of the higher and higher emission standards of the factory gas stipulated by the state, and the higher and higher efficiency of the dust collector. In all the dust collector, bag filter is relatively widely used in various factories in the dust removal equipment. This
