Appliance coating and electroplating sectors: energy saving preventive measure

"Household appliance manufacturing process no gas and solid waste emissions, and only a small number of production processes of water pollution. In contrast, focus on energy saving household appliances industry is not in the production process, but in the product." Accepting " Electric "when reporters talk about the appliance's energy saving production process, the Chinese Household Electrical Appliances Association vice chairman and secretary general Jiang Feng said.

However, in the national "energy conservation" policy, under pressure, especially the State Department in 2007 in the "unit GDP energy consumption monitoring system for implementation of the proposal" put forward, on the annual energy consumption of more than 10,000 tons of standard coal enterprises focused monitoring, home appliances manufacturing sectors of energy production and capacity of sewage problems began to receive attention.

Reduce emissions at source

January 1, 2008, the State Council presided over for the China Pollution Source Census has officially begun, including the inspection of industrial enterprises is the core content. To ensure the smooth development of the census, in September 2007, China Household Electrical Appliances Association by the authorities entrusted with the discharge coefficient of household appliances refrigeration industry accounting of production.

According to "appliances" to report, the accounting work, in fact, home appliance industry is the state investigation of the sewage situation. China Household Electrical Appliances Association official said: "The future is likely to introduce specific measures for emission reduction, household electrical appliance enterprises must pay attention to business and emission reduction."

According to a comprehensive home appliance manufacturer person in charge of Energy Department, there are air conditioners, washing machines, refrigerators, freezers and other products, production processes are the main pollutants emitted in the spray part skim phosphoric. Such as refrigerator production in the spray tank shell surface pre-treatment processes, air-conditioning outdoor unit casing before spraying the surface of the sewage treatment processes is the main process. Refrigerators, air-conditioning in the phosphate treated coating operations, using the electrostatic spraying process, its use is the main component of the solid powder of pure polyester powder, which does not contain organic solvents in solid powder, it need not be dispersed organic solvent medium, in the spraying does not produce organic waste, only a small amount of powder generated during the coating of dust, but recovered after the discharge may reach the national standard.

Million and the market told the Minister Xu Weiguo, "electrical" reporters, kitchen appliances in the production process, mainly in two areas spraying and electroplating emissions of harmful substances, which emit in the course of a number of spray containing acid, alkali and heavy metal ions water, in the electroplating process, will be discharged with organic matter, including cadmium, nickel, lead and heavy metals, including sewage.

"Household appliance manufacturing wastewater generated in the process method of phosphorus removal by chemical coagulation and other contaminants, into the municipal pipe network system. Some smaller appliances machine companies are outsourcing part of spraying in the specialized processing treatment, only to assemble products, household electrical appliance enterprises assembly process therefore does not exist in the emission of pollutants. In addition, many large enterprises have passed the ISO14000 environment management system certification in handling hazardous substances are regulated and so long . "said the head of a household electrical appliance enterprises.

Main controls

At the same time, local governments have also launched energy-saving emission reduction for enterprise implementation. A home appliance enterprises in Guangdong to the "electrical" journalists from the local government issued a "save thousands of self-examination and evaluation of corporate responsibility for energy-saving goal scoring table", according to the requirements of the table, companies need to develop energy conservation plans, if at the end of maturity not achieve the promised targets will be subject to certain penalties.

This situation is the production process management and technological innovation has put forward new demands. According to "appliances" to report, Haier washing powder production line was the traditional method, will result in waste and inefficient powder. Haier powder line transformed into "kangaroo dusting" laws, not only reduced the amount of angle plate spray, powder box also improves the efficiency. Reduce the amount of the monthly board spray angle 200kg, saving costs 2,800 yuan; powder efficiency, daily more than 700 cabinet spray, cost-saving 60 thousand yuan per month.

"Electric" This reporter noted that the current household electrical appliance enterprises when new factories and production lines have great attention to energy saving design. Beijing Embraco Snowflake Compressor Co., Ltd. The new plant construction, the 400,000 U.S. dollars into building the two sewage treatment plant (industrial wastewater and domestic sewage), 50% of the wastewater reuse has been achieved (the green area of the factory All irrigation water comes from water reuse). Hailigufen Nanchang plant construction in its plan, the proposed construction of "green factory." For example, in architectural design to consider rainwater harvesting, recycling of industrial water and waste heat production, natural light and efficient use of solar energy in daily life, also has been incorporated into the design plan.

In fact, many energy-saving home appliances business in the past few years has made some progress. "Haier Group in 2006, through the Division of cleaner production, formation cost 51.15 million yuan in annual emission reduction waste water 150,000 tons, the annual emission reduction COD (chemical oxygen demand) 327 tonnes." Yang Mian Mian, president of Haier Group said recently.

Matsushita Wanbao (Guangzhou) Compressor Co., Ltd. introduced by reduction of lead and nitrogen oxides, sulfur dioxide emissions and iron recycling activities, improve the comprehensive utilization of plant energy efficiency, water efficiency, emissions and other pollutants.

HaiLi limited liability Company, General Manager Chen Jianfang proudly said: "Shanghai Hitachi present value of GDP energy consumption is 137kg million standard coal, far below the industry average level of China."
