Under the background of upgrading environmental protection standards, the treatment of pollutants in the cement industry has entered a critical period. Unorganized emissions have become a short board restricting the upgrading of environmental protection in the cement industry because of the many links involved and the difficulty of supervision.
Recently, China Cement Network interviewed Mr. Wu Shangan, former Secretary-General of Bag Dust Removal Committee of China Environmental Protection Industry Association, former professor-level senior engineer of Hefei Cement Research and Design Institute and senior consultant of China Cement Network. It focuses on the technical control path and operation and maintenance optimization method of unorganized emission in cement enterprises, and provides reference for enterprises to solve emission problems and achieve environmental protection upgrading.
1. Technical level: Focus on sealing and negative pressure operation, and the difficulty of governance is controllable
. Although it is difficult for environmental protection departments to formulate relevant ultra-low emission technical policies, the nature of unorganized emission of cement enterprises is a long-term environmental debt problem, which is not difficult to solve from the technical level. Unorganized emissions mainly involve particulate matter emissions, not nitrogen oxides, sulfur oxides and other harmful components. As long as the technical level achieves sealing treatment and negative pressure operation, it can be effectively controlled, and some enterprises have achieved good practices of ultra-low emissions.
2. Management level: Strengthen operation and maintenance and promote intelligent upgrading
. The prominent problem of current unorganized emission control lies in inadequate operation and management. After long-term use, the dust collectors equipped at the top and bottom of raw fuel depots and cement depots in some old enterprises have been basically paralyzed due to the high cost of operation and maintenance. In this regard, the promotion of intelligent management advocated by China Cement Network is very important, such as the palm inspection mode in the environmental protection industry, real-time monitoring of the working status of bag filters through terminal equipment and mobile phones, so that problems can be found and repaired in time without manual inspection.
3. Investment level: Face up to historical debts and increase investment
in governance. In the review of technical standards, it is mentioned that the environmental protection "debts" accumulated by the cement industry due to the disorderly development in previous years must be repaid, and the core of repayment lies in investment. These debts are due to insufficient investment in environmental protection in the past, and the core support for repayment lies in the continuous increase of investment in governance to provide a financial basis for upgrading and maintaining environmental protection facilities.
At present, the cement industry is facing the double test of energy saving, environmental protection and industrial intelligence upgrading. In order to implement the relevant policy requirements and accelerate the green low-carbon transformation and high-quality development of the cement industry, China Cement Network is scheduled for September 23-24. The 14th China Cement Energy Conservation and Environmental Protection Technology Exchange Conference and the 6th Intelligent Summit Forum were held in Zibo, Shandong Province.
This conference will bring together industry experts, enterprise representatives and many industry stakeholders to gather group wisdom and promote energy-saving, environmental protection and intelligent transformation and upgrading of the cement industry. At that time, Mr. Wu Shangan will have an in-depth exchange with you on how to promote environmental protection management in current cement enterprises. During
the meeting, we will also organize a visit to the demonstration project of Qingzhou Zhonglian Cement Co., Ltd. with an annual output of 200000 tons of carbon dioxide oxy-fuel combustion coupled carbon capture.
