Study On The Heating System Transformation Of Daqing Petroleum Institute

Heating engineering technology have progressed continuously based on promoting the comfort, health, the protection of earth environment and the effective utilization of energy of human residence. The heating network which plays a particularly important role is the connection tie of the whole heating system engineering. So it is critical to the design of the heating network.The heating network is a complex fluid network system, whose the run condition is affected by many aspects such as working condition, environment,construction. Hydraulic disorder is the common phenomenon in the heating network, so the problem facing the heating industry is how to overcome hydraulic disorder, realizes the hydraulic balance of the heating network that improves the heating quality, increase the economy, reliability and safety of pipe network.The factors that cause heating state and heating effect are complex, which are the factors that the hydraulic disorder of pipe network results in the heating imbalance, the heat consumption of monomer envelope is large and the heat load of heating system is lower, as well as the operation parameters of heating system can't meat demand. Therefore, when a certain heating network has appeared the problem that the heating imbalance, it is not simply a factor as verdict, but should be comprehensively considered that overcome the problem fundamentally.This paper designs and analyses the problems of heating imbalance in daqing petroleum institute heating network and heating effect that unsatisfactory generally. Because of the heating effect of three periods student apartment is stronger representative, in the process of design, this paper takes the three periods student apartment for example. This paper first conducted the check calculation for the heating system of single building, and then made the local regulatory about heating system and discussed the laying, insulation and anticorrosion of pipeline and other related correlation. Finally, it analyzed the whole external network, the reason of external network was found, and the improving plan was put forward in its regional. At the end, this paper used the fluid network to anglicize the heating network and made economic comparison of using small caliber throttle technology and using balance valve in the heating network system transformation of daqing petroleum institute.According to the research results of this paper, exemplified by three periods student apartment of daqing petroleum institute, as example the hydraulic calculation of system was carried out and the concrete modification scheme was putted forward, which has the guiding significance in engineering application.
