1 问题的提出本钢余热开发公司现有五条向市区供热的管网,这五条管网现基本处于满负荷运行状态,即在现有的基础上已不能再发展供热面积,但是随着城市建设的发展,一些新的建筑设施急待供热,如何解决这一矛盾是摆在我们面前的一个新的课题。2 初步设想我们经过分析认为,提高热源水温,增大系统的循环流量,利用混水设备是解决这一问题的方法。我们考虑到混水泵的造价太高,并且耗费电能,还需经常维修,故此,我们想到了水—水喷射器,利用水—水喷射器把一建筑物的供回水混合,把这种
1 Problems The Bengang Steel Residual Heat Development Co., Ltd. has five existing pipe networks for urban heating. These five pipe networks are basically in full-load operation, that is, on the existing basis, the heating area can no longer be developed, but With the development of urban construction, some new building facilities are in urgent need of heating. How to resolve this contradiction is a new topic before us. 2 Initially envisaged that after analyzing, we believe that increasing the water temperature of the heat source and increasing the circulating flow of the system and using the water mixing equipment are the methods to solve this problem. We considered that the cost of a mixed water pump is too high, and that it consumes electricity and requires constant maintenance. Therefore, we thought of a water-water injector that uses a water-water injector to mix the water from a building’s supply and return water.
