新一轮环保风暴下 国内红木家具企业该如何应对

The second round of environmental supervision started on August 20 and ended on April 28, 2019, according to the "Plan for Intensive Supervision of Key Areas in Blue Sky Defense War 2018-2019" issued by the Ministry of Ecological Environment.
A new round of environmental storm, covering the 2 + 26 cities, Fenwei Plain, Yangtze River Delta and the Pearl River Delta manufacturing industry, mahogany furniture industry is no exception. In the last round of environmental supervision, mahogany enterprises have reflected and adjusted a lot of production and equipment problems, and then how to continue to improve and do a good job in environmental protection issues, the United Art Mahogany Furniture Committee expert consultant, China mahogany furniture expert Cao Xinmin, gives five suggestions.
Entrepreneurs should learn two major national laws
As the first rosewood industrial cluster in China, Dayong Town, Zhongshan City, Guangdong Province, has undergone more than 40 years of development. It should develop in a green, intelligent and sustainable direction in the current industrial upgrading. Entrepreneurs should be aware of their social responsibilities and learn and abide by the Environmental Protection Law of the People's Republic of China and the Cleaner Production Promotion Law of the People's Republic of China. Take the initiative to undertake the responsibility of enterprises in environmental governance and raise the level of governance.
Drying, special drying and drying of parts are the focus of technology.
Wood drying accounts for about 70% of the energy consumption in mahogany furniture factories. At present, the cost of heat energy is increasing year by year. It is difficult to solve the problem of central heating in two big industries in Dayong in the short term. The prohibition period of small boilers is approaching. Therefore, the demand for new-type heat energy in sawn timber drying of mahogany enterprises is very urgent. It's not a business problem. The future mahogany furniture enterprises will inevitably increase the investment of scientific and technological change funds to energy-saving, efficient, environmental-friendly drying technology and advanced equipment. The single steam thermal energy should be transferred to the common direction of solar energy, electric energy, industrial high temperature heat pump and other new energy sources. Conditional enterprises can also unite to establish photovoltaic power generation system, make full use of state support policies, reduce the cost of electricity consumption in wood drying. Combined drying, special drying and parts drying will be the focus of future technological progress of "gushing drying".
Ensure the maturity and reliability of "common factory" technology.
One of the keys to harnessing harmful substances in mahogany furniture manufacturing enterprises is painting and drying. The construction of "commonness factory" in Dayong Town, Zhongshan City, attempted to solve the problems of paint exhaust gas and waste water treatment in small and medium furniture enterprises by intensive means, which paved a new way for the industry and created new experience. For the "common factory" to ensure the maturity and reliability of technology; to establish a standardized operational, traceable management system; to use information technology to achieve the "common factory" all the process of intelligent monitoring. "Common factory" is actually a perfection and optimization of the rosewood industrial chain at this stage, not the value chain. Therefore, the layout of Dayong should be demonstrated and accelerated, not for the main purpose of pursuing efficiency. For the "common factories", the government should strictly supervise and tolerate zero tolerance.
车间必须安装通风除尘系统 新上系统一定要小
Workshop must install ventilation and dust removal system, new system must be small.
Wood dust produced by mahogany furniture factories is also one of the key hazards. Compared with modern furniture enterprises, the occupational hazards of mahogany furniture enterprises are more serious, and the working environment is worse. Ventilation and dust removal systems must be installed in the workshops, which are discharged after reaching the comprehensive emission standards of atmospheric pollutants (GB16297-1996). The air in the room is purified. Except for the unloading workshop of large enterprises, the dust removal system should not be large. Dust removal system in solid wood factories is not suitable for the labor organization structure of mahogany furniture factories. When the dust removal system is turned on, the turning-on rate of woodworking machine tools is usually less than half of the corresponding suction hood. This not only causes the system start-up utilization rate is not high (power waste is too big), the investment cost is large, and the role is not good. Because the design of pneumatic dust removal involves pressure balance in the main road, it is difficult to change once built. In the future, before the system, the process production path within the scope of the system must be designed scientifically, can not follow the old system, dust removal system design must be in line with the market. It is suggested that the new system should be composed of small and multiple small systems, especially multi-storey industrial plants, with air handling capacity between l0000 and l5000 cubic meters per hour, adopting the principle of negative pressure pneumatic bag dust removal, internal ultra-low pressure technology, fan built-in, automatic dust removal, intelligent induction and automatic control (variable air volume, wind pressure) when starting up. ), energy conservation and consumption reduction.
Workshop layout design should be "quiet and quiet".
Woodworking machine noise frequency is high, noise is one of the key hazards to control, especially the noise produced by circular saw, it is the most sensitive noise area of the human ear, the greatest impact on workers'health, most woodworking circular saw idling noise above 90 dB (A). Noise control is mainly carried out from two aspects: first, the structural improvement of woodworking machine tools themselves; second, in the process layout design of the workshop, it is necessary to "noise and quiet zoning". The main and commonly used equipment is centralized in the equipment room, and the plane of the building between the equipment room is treated by noise reduction structure. This process arrangement is not only beneficial to noise reduction, but also beneficial to the plant layout. The dust removal design has a good effect on clean production in the workshop.
