Add a city of Shandong issued furniture manufacturing VOCs emission standards

(Hereinafter referred to as "standard") has been approved by the provincial government, the provincial Environmental Protection Department, the Provincial Quality Supervision Bureau officially released, will be implemented on September 3, 2017 (hereinafter referred to as "the standard of emission of organic organic matter" , Which is the province of volatile organic compounds in the third part of the emission standards. To facilitate the public to fully understand the background of the preparation of the standard, the main ideas, technical feasibility, etc., do the following interpretation.
First, the "standard" preparation background
Volatile organic matter (VOCs) is an important precursor of urban haze and photochemical smog, mainly from chemical production, fuel paint manufacturing, solvent use and other processes, some VOCs have carcinogenic, mutagenic, teratogenic, Human health causes harm.
The manufacturing process of the furniture manufacturing industry belongs to the process of using the solvent and is an important source of VOCs in the ambient air. Our province is a large province of furniture industry, the size of the main business income accounted for 12% of the country, of which the total output of solid wood furniture ranked first in the country. Our furniture surface coating process using a wide range of paint and organic solvents and the amount of large, most of the enterprise production workshop and paint storage workshop is poor, and failed to equip with effective pollution control facilities, resulting in large VOCs emissions, and to Unorganized emissions. Therefore, the development of furniture manufacturing VOCs emission standards for the control of pollution, improve the quality of the atmospheric environment is of great significance.
Second, the furniture manufacturing industry VOCs emission characteristics
The VOCs emissions from furniture manufacturing are related to the type of coating. When coating the same area, the use of oil-based paint to produce the most VOCs, followed by water-based paint, powder coating at least. Our province furniture manufacturing enterprises mainly use the production process of polyurethane coatings, nitro-based coatings, alkyd paint and other oily coatings, VOCs emissions. Furniture manufacturing VOCs emissions are also related to coating technology. When coating the same area, the air spray technology produces the most VOCs produced by electrostatic spraying and brushing. Most of our province furniture manufacturing enterprises to air-based, in the furniture production process to be repeated primer and topcoat spray operation, resulting in low paint use, VOCs emissions. Furniture manufacturing VOCs emissions and workshop closures and end control measures also have a great relationship. Most of the furniture manufacturing enterprises in our province's production workshop is semi-closed form, the distribution of production equipment is not concentrated, some enterprises only focus on pollution, more serious paint stations, drying stations and other stations to produce waste gas collection and processing, And most of the organic waste gas is still in the form of unorganized emissions. And a considerable number of enterprises did not take any end-of-management measures, some enterprises only install water absorption and other simple VOCs management facilities, VOCs processing efficiency is low, resulting in large emissions of VOCs.
Third, the current furniture manufacturing industry feasible VOCs waste gas pollution control measures
Furniture manufacturing industry VOCs exhaust gas treatment can be divided into prevention and treatment of two ways. "Anti-" is mainly the source control, that is, by improving the low organic solvent content of environmentally friendly coatings (water-based paint or powder coating) to use the proportion of improved coating technology (spin cup atomization electrostatic spraying, air atomization electrostatic spraying, brush Coating, roller coating, etc.), research and development of intelligent coating test line, coating workshop fully closed and other methods to reduce the generation of VOCs. "Governance" is mainly on the coating process of production of VOCs produced in the exhaust gas collection and purification treatment. Combined with the province of typical furniture manufacturing enterprises on-site research and various types of furniture manufacturing enterprises research results, furniture manufacturing VOCs exhaust more efficient treatment measures include water absorption + activated carbon adsorption process, regenerative catalytic combustion (RTO) and so on.
From the province of furniture manufacturing enterprises coating process level, pollution control technology and research data, the enterprise can take raw material adjustment, improve the spraying process or spraying technology, supporting efficient pollution control facilities, etc. to achieve discharge standards.
