Oven waste heat recovery equipment adopts heat exchange and exhaust principle

After four months of solicitation and evaluation, students from 63 schools across the country will finally realize their water-saving dreams in their communities with the support of the "keep a bucket of water" environmental campaign.
 
The solicitation of proposals for the 2009 "save a bucket of water" environmental campaign, which began in March, has been completed, reporters learned Tuesday. Middle school students and college students in 12 cities and regions across the country took advantage of practical courses to carry out research on optimal use of water resources and design water-saving schemes, and participated in this environmental protection action. Finally, experts selected 63 excellent schemes with strong operability and good water-saving effect from more than 100 schemes.
 
Liu yankai, deputy director of the urban water conservancy professional committee of China water conservancy association, who participated in the review, pointed out that the excellent programs selected all reflect students' creativity and practical ability. For example, the students in no.12 middle school in shijiazhuang designed the activated water-saving faucet with the lever principle, which greatly reduced the water consumption of washing hands and face. Compared with the infrared sensing water-saving faucet, it is more convenient and affordable and easy to be popularized in schools and families. Plans are under way to patent the design. However, students of taiyuan university of technology use curved pipes to store the bath water into the storage tank for cleaning and then flush the toilet, which solves the problem of large water consumption in public bathrooms and difficulty in recovering the bath water.
 
Many students also focused on the community. For example, students of hangzhou zhongce vocational school collect rainwater by collecting flume, which is used for flushing water in community public toilets. Students at tsinghua university in Beijing put forward plans to transform green space irrigation in residential areas and to replace the type of water-saving grass.
 
"Although the proposals submitted by the students were different in theme, they all showed their environmental awareness and innovation ability." "Said liu yankai.
 
The proposals submitted by students in some rural schools are highly targeted. For example, students at yangsong middle school in huairou district of Beijing installed anti-overflow devices on solar water heaters using timers on discarded washing machines.
 
Zhao yixin, director general of the Beijing environmental protection foundation, said the task of saving water in rural areas is more difficult under the constraints of economic conditions and weak awareness of water conservation. Students from rural areas use their knowledge to contribute to saving water in their hometown, which is worth encouraging and advocating.
 
Liu yankai stressed that water saving should not be on paper. To this end, the "keep a bucket of water" environmental action has set up a "green fund", which is provided by students with the program budget under the guidance of experts, and funded by the sponsor for the implementation of excellent programs in the community.
 
The "keep a bucket of water" campaign is jointly sponsored by Beijing education committee, Beijing environmental foundation, education research center for sustainable development of Beijing education research institute and Coca-Cola (China) beverage co., LTD.
