the mass circulation Daily News seawater more than 20,000 tons of sulfur dioxide a year away, the whole process without adding any reagent, does not produce any by-products, does not affect sea ecology, water desulfurization technologies charm is evident.

8 Yue afternoon of 31, Huadian Power Company, Qingdao, 1,2, 30 kilowatt generator set, sea water flue gas desulphurization through technical transformation project of Qingdao Environmental Protection Agency acceptance. Qingdao Power Company became the first one in north China’s power generation using seawater desulphurization technology companies in Qingdao in the atmosphere each year and therefore will be reduced by more than 20,000 tons of sulfur dioxide pollutants.

Huadian Power Company, Qingdao, the expansion project of 1,2, 30 kilowatt generator set, boiler capacity of 1025 tons per hour, is the largest city of Qingdao, coal-fired boilers, the annual coal about 154 million tons. As Qingdao’s largest power generation and heating company, Qingdao Power Company is also a Castle large amount of sulfur dioxide emissions. In order to reduce air pollution in recent years, the company actively burning low-sulfur coal, it is also exploring more efficient ways to save the desulfurization. In the environmental protection department’s help, finally chose the technology is mature more than 90% desulfurization efficiency and investment, lower operating costs of seawater FGD. The project total investment of 373 million yuan last year, civil works commenced in March this year, April 30 and June 15, 1,2 Units of seawater flue gas desulphurization equipment has been put into operation after commissioning.

generating companies, according to deputy general manager of Qingdao, WANG Xiu-lin introduction, seawater desulfurization works are: boiler flue gas through the electrostatic precipitator processed through the induced draft fan booster fan booster and entered through the absorption tower, the sea water through the booster pump into the absorption tower, spray from top to bottom, bottom of the flue gas to absorb sulfur dioxide, sulfur dioxide after absorption of acidic water routed to aeration tanks, for water quality restoration treatment, the oxidation of sulfite ion sulfate ion to raise the PH value of water to achieve discharge standards.

“Seawater FGD process uses sulfur dioxide absorbed in seawater Trona, throughout the absorption system and the water recovery system, without adding any reagent.” WANG Xiu-lin said. Furthermore, the whole process does not produce any by-product of the Jiaozhou Bay waters near the ecological environment will not be adversely affected. “At present, similar to the seawater desulphurization equipment only in the Shenzhen West Power Plant, and the post-rock power plant in Zhangzhou some applications, in China’s Yangtze River north of the region is the first application.”

Two experts Qingdao Environmental Protection Bureau boiler flue gas flow, efficiency and desulfurization desulfurization scrubber water discharge after the PH value of exports carried out on-site monitoring results show that, two seawater desulphurization equipment, desulphurization efficiency is higher than the design value, reaching more than 90%, PH value of water reached 6.88-7.4, fully meet the discharge standards. By design, this standard Qingdao Power Company 22,000 tons of sulfur dioxide emissions a year.

“Qingdao Power Company’s water desulfurization project is a prevention and control of air pollution in Qingdao, a key project. At present, Qingdao City, sulfur dioxide emissions by 15 million tons, the reduction of seawater desulfurization project 22,000 tons, accounting for about 15% of the total to ensure that the ‘Eleventh Five-Year’ at the end of sulfur dioxide emissions fell to 114.5 thousand tons goals. “Qingdao Environmental Protection Bureau deputy director of Songchun Kang said.

城堡通过海水中的污染物减少15％的脱硫项目验收

发行量每日新闻海水超过20,000吨的二氧化硫一年了，无添加任何试剂，不产生任何副产品，不影响海洋生态，水脱硫技术的魅力，整个过程是显而易见的。

8越31日下午，华电公司，青岛，1,2，30万千瓦发电机组，海水通过青岛市环境保护局验收技改工程烟气脱硫。青岛电力公司，成为中国北方的发电利用青岛海水脱硫技术在大气中的公司每年因此将超过20000吨，二氧化硫减少污染物第一个。

华电电力公司，青岛，1,2扩建工程，30万千瓦发电机组，锅炉每小时1025吨的生产能力，是青岛，煤炭最大的城市燃煤锅炉，每年的煤炭约一万五千四点〇万吨。作为青岛市最大的发电和供热公司，青岛电力公司也是一个城堡中二氧化硫的大量排放。为了减少空气污染，近年来，公司积极燃烧低硫煤，也是探索更有效的方式来保存脱硫。在环保部门的帮助下，最终选择了技术成熟的90％以上，脱硫效率和投资，降低运营成本的海水烟气脱硫。该项目的3.73亿元，总投资去年开始土建工程在今年3月，4月30日和6月15日，1,2机组海水烟气脱硫设备已投入使用后启用。

发电公司，据青岛市副，王修林介绍，海水脱硫工程总经理：通过通过引风机增压风机助推器的静电除尘器处理锅炉烟气进入吸收塔通过的通过海上进入吸收塔，从上到下，对烟气底喷增压泵水吸收二氧化硫，硫后改为曝气池酸性水的吸收二氧化碳，水质恢复治疗，亚硫酸盐离子氧化硫酸根离子，提高水的PH值达到排放标准。

“海水烟气脱硫工艺的使用在整个吸收系统和水回收系统在海水中的二氧化硫吸收天然碱，不添加任何试剂。”王修林说。此外，整个过程不产生任何的胶州湾附近海域的生态环境的产品将不会受到影响。 “目前，类似于海水脱硫设备仅在深圳西部电厂，和后岩漳州电厂的应用在中国的一些公司在长江以北地区，是第一个应用程序。”

两名专家青岛市环境保护局锅炉烟气流量，效率和出口后的PH值进行了现场监测结果表明，两个海水脱硫设备，脱硫效率高，比设计脱硫脱硫洗涤水排放值，达到90％以上，PH值对水的价值达到6.88-7.4，完全符合排放标准。按照设计，这个标准青岛电力公司2.2万吨，二氧化硫年排放量。

“青岛电力公司的水脱硫项目是预防和空气在青岛，污染控制重点项目。目前，青岛市，15万吨，海水脱硫工程2.2万吨，减少二氧化硫排放量核算约占总数的15％，以确保’十一五’的二氧化硫排放量下降到了年底一十一点四五○万吨目标。“青岛市环境保护局松纯康副主任说。06.9.8
