ZHENJIN REFRACTORIES takes the use of pollution reduction and carbon reduction synergy as the main starting point, and implements the whole-process pollution prevention and control concept that combines source reduction, process control and end-point treatment, improves resource utilization efficiency, promotes energy conservation and carbon reduction, and promotes ambient air quality. Continuous improvement and high-quality development of the enterprise.
In June 2022, seven ministries and commissions including the Ministry of Ecology and Environment, the National Development and Reform Commission, the Ministry of Industry and Information Technology, the Ministry of Housing and Urban-Rural Development, the Ministry of Transport, the Ministry of Agriculture and Rural Affairs, and the Energy Administration jointly issued the "Implementation Plan for Synergistic Efficiency of Pollution Reduction and Carbon Reduction". "(hereinafter referred to as the "Plan"), the "Plan" put forward the requirements of "building a new development pattern, promoting high-quality development, and taking the realization of pollution reduction and carbon reduction synergy as the general starting point for promoting a comprehensive green transformation of economic and social development", Clarify the working principles of "highlighting synergies, strengthening source prevention and control, optimizing technology paths, focusing on mechanism innovation, and encouraging first and foremost trials".
ZHENJIN REFRACTORIES actively responded to the "Plan", put forward optimization plans from the aspects of energy saving and consumption reduction, process optimization, improvement of governance level, unorganized control, monitoring and supervision level, adjustment of transportation mode, etc., and explored the synergistic path of pollution reduction and carbon reduction in the refractory industry.
1.Promote energy conservation and consumption reduction, and promote the green development of the industry
In Xinmi City, the hometown of refractories in China, there are more than 800 refractory enterprises. ZHENJIN REFRACTORIES is resource-oriented, actively optimizing industrial layout, improving product quality, optimizing product technology, and striving to develop high-quality green and low-carbon refractory raw materials and products. Improve resource utilization and reduce resource consumption at the source. Promote the comprehensive utilization of raw material industrial solid waste, actively utilize coal gangue, red mud and other tailing resources and refractory materials after use, reduce the dependence on primary resources, and improve the comprehensive utilization level of resources. Strictly control the consumption of fuel coal and reduce the comprehensive energy consumption per unit of refractory products of high-energy-consuming equipment such as high-temperature kilns. Strengthen the recovery and utilization of high-temperature bulk material and liquid slag waste heat, waste heat of dusty exhaust gas, and low-grade waste energy.
The development of China's refractory technology has clarified the clean production development technology based on process optimization. ZHENJIN REFRACTORIES keeps up with the pace of the country, continuously innovates and creates refractory materials, and introduces European refractory brick intelligent inspection and selection production lines and palletizing robots to improve the level of automation. , to achieve intelligent production. Using advanced technology and equipment with a high level of automatic control, in terms of technological processes such as intelligent raw material storage three-dimensional warehouse, automatic batching system, automatic molding production line, automatic temperature-controlled ultra-high temperature tunnel kiln, and intelligent online inspection of the production process, the transformation from mechanization to automation is realized. , intelligent forward, from the traditional to the modern leap.
2.Improve the level of pollution control and reduce the intensity of organized emissions
The pollutants in the refractory industry come from the storage, transportation, batching, processing, packaging, and kiln firing and drying of raw and auxiliary materials, mainly including particulate matter, sulfur dioxide, nitrogen oxides, and some raw materials and products The production process involves VOCs For discharge, the terminal needs to be equipped with dust removal, desulfurization, denitrification and other facilities. ZHENJIN REFRACTORIES adopts SCR, SNCR and other desulfurization and denitrification facilities, and dust removal adopts high-efficiency dust removal processes such as film-coated bag dust removal, wet electrostatic dust removal or electric bag dust removal, and the designed dust removal efficiency is high. At 99.9%; desulfurization at the end of the production line adopts lime/stone-gypsum method, semi-dry method/dry method and other processes; except for drying kilns and heat treatment kilns, denitrification adopts SCR/SNCR and other processes, which can effectively reduce the light emission and achieve green development. And in 2021, it will receive honorary titles such as "Green Factory" and "Smart Factory".
3.Strengthen fugitive management and control capabilities and reduce fugitive emissions
Unorganized emissions are one of the important sources of pollution for enterprises. Strictly control unorganized emissions in the production process of industrial furnaces and related materials storage and transportation. On the premise of ensuring production safety, effective measures such as airtightness and sealing are adopted to effectively reduce waste gas emissions. Collection rate, dust producing point and workshop shall not have visible fume and dust escaping. In order to avoid excessive emissions, ZHENJIN REFRACTORIES adopts measures such as sealing, sealing and setting up gas collecting hoods at the dust production points (devices) in the production process. Pulverized coal, fly ash, lime, dust removal ash, desulfurization ash and other powdery materials are stored in airtight or closed storage, and conveyed by means of closed belts, closed corridors, and tubular belt conveyors. Granular and block materials are stored in sheds and warehouses, and windproof and dust-suppressing nets are constructed for storage. In addition, ZHENJIN REFRACTORIES requires materials to take effective measures such as sealing. The material crushing and preparation and molding process should be carried out in a closed workshop, and equipped with dust removal measures, the material shed is equipped with dust suppression facilities, and the material shed entrance and exit are equipped with automatic doors.
ZHENJIN REFRACTORIES takes the use of pollution reduction and carbon reduction synergy as the main starting point, and implements the whole-process pollution prevention and control concept that combines source reduction, process control and end-point treatment, improves resource utilization efficiency, promotes energy conservation and carbon reduction, and promotes ambient air quality. Continuous improvement and high-quality development of the enterprise.
