【摘要】：能源與環(huán)境是當(dāng)今世界的兩大主題,節(jié)能減排是我國的基本國策,節(jié)約能源、降低成本是企業(yè)生存及發(fā)展的必由之路。本文針對化工企業(yè)耗能的特點(diǎn),并響應(yīng)“節(jié)能減排”的規(guī)劃目標(biāo),提出了以水動(dòng)風(fēng)機(jī)代替電動(dòng)風(fēng)機(jī)的循環(huán)水風(fēng)機(jī)節(jié)能改造方案。作為核心設(shè)備的高效率水輪機(jī),收集進(jìn)入布水器釋放的能量,從而推動(dòng)風(fēng)機(jī),節(jié)約能源。要確保改造后的水動(dòng)風(fēng)機(jī)轉(zhuǎn)速滿足原系統(tǒng)要求,水輪機(jī)輸出的有效軸功率應(yīng)大于原電機(jī)軸功率。風(fēng)機(jī)改造的成功需要保證在現(xiàn)有藥劑作用下,循環(huán)水質(zhì)不發(fā)生較大變化或產(chǎn)生不利于換熱設(shè)備正常運(yùn)行的影響。本研究共進(jìn)行11次試驗(yàn),采用兩種殺菌滅藻劑,并以一種殺菌劑正常投加為主,另外一種間歇投加的方式進(jìn)行試驗(yàn)以觀察循環(huán)水中藻類、細(xì)菌生長繁殖情況及對循環(huán)水系統(tǒng)的影響。后續(xù)的試驗(yàn)依托前次試驗(yàn)的試驗(yàn)結(jié)果,對循環(huán)冷卻水中殺菌滅藻劑的量進(jìn)行調(diào)整,以獲取最佳的投加量。實(shí)驗(yàn)結(jié)果表明,循環(huán)水風(fēng)機(jī)改造成水輪機(jī)后,不同添加量的殺菌滅藻劑對循環(huán)水的濁度和磷濃度影響較小,不會增加水垢及藻類的產(chǎn)生。項(xiàng)目改造后,循環(huán)水系統(tǒng)冷卻風(fēng)機(jī)運(yùn)行平穩(wěn),水質(zhì)滿足系統(tǒng)各項(xiàng)控制指標(biāo)要求。本文選取惠生(南京)清潔能源股份有限公司的循環(huán)冷卻水風(fēng)機(jī)節(jié)能改造項(xiàng)目進(jìn)行投資效益評價(jià)。節(jié)能改造后項(xiàng)目的成本比改造前降低105.8萬元／年,改造后的循環(huán)水系統(tǒng)具有明顯的節(jié)能效果,為同類項(xiàng)目節(jié)能改造提供了指導(dǎo)依據(jù)。
[Abstract]:Energy and environment are two major themes in today's world, energy conservation is a basic national policy, China's energy saving and cost reduction is the only way which must be passed of the survival and development of enterprises. Based on the characteristics of chemical enterprises of energy, and in response to "planning energy-saving emission reduction targets", put forward by the water moving fan instead of electric fan cycle water fan energy-saving renovation project. As a high efficiency turbine core equipment, collected into the water distributor of energy released, thus promoting the fan, energy saving. To ensure that after the transformation of the water driven fan speed to meet the original requirements of the system, effective shaft power of the turbine output power should be greater than the original transformation of fan motor shaft. The success of the need to ensure that the existing chemicals under the action of the circulating water does not change or not conducive to the heat exchanging effect the normal operation of the equipment. This study conducted 11 experiments using two kinds of bactericidal algicide, and A fungicide normal dosage, another way of intermittent dosing test to observe the circulating water algae, and affect the circulating water system of bacteria growth and reproduction. The test results based on the first test of the follow-up, the circulating cooling water sterilization algicide amount is adjusted to obtain the best the dosage. The experimental results show that the circulating water fan into the water turbine after sterilization in different quantity out smaller algicide turbidity and phosphorus concentration of circulating water, will not increase the scale and production of algae. The project is the transformation of circulating water system, cooling fan running smoothly, water quality control indicators meet the system requirements. This paper chooses Wison (Nanjing) clean energy investment benefit evaluation of the Limited by Share Ltd's circulating cooling water fan energy-saving renovation project. Energy saving project cost reduced 1 million 58 thousand yuan over the previous transformation / year, the reformed circulating water system has obvious energy saving effect, which provides guidance for energy-saving reconstruction of similar projects.
