【摘要】：近年來,空氣環(huán)境持續(xù)惡化,霧霾、揚(yáng)塵天氣出現(xiàn)次數(shù)愈發(fā)增加,政府每年都在加大投入治理空氣污染,幾個(gè)大氣污染指標(biāo),如總懸浮顆粒、降塵、二氧化硫、氮氧化物,北方城市高于南方城市,采暖期重于非采暖期。采暖期城市大氣污染指標(biāo)普遍超過標(biāo)準(zhǔn),其基本原因,就是采暖熱煤釋放的污染物。未來,采暖建筑越來越多,污染物的釋放量也越來越大,環(huán)境指標(biāo)越來越惡化。因此,改善大氣質(zhì)量的重要措施之一就是發(fā)展城市集中供熱。本文將詳細(xì)闡述熱源與供熱運(yùn)行之間深層次的聯(lián)系,讓更多從事集中供熱的人員能夠從新的角度考慮問題,為更多的人提供運(yùn)行經(jīng)驗(yàn)上的參考。首先,本文將對(duì)多熱源集中供熱系統(tǒng)的多種運(yùn)行方式的利弊進(jìn)行探討,根據(jù)大連市的實(shí)際情況,確定一種運(yùn)行方式,結(jié)合大連大發(fā)供熱公司的管網(wǎng)實(shí)際運(yùn)行情況,對(duì)管網(wǎng)最佳運(yùn)行方式、熱負(fù)荷的高溫水流量分配及運(yùn)行中出現(xiàn)的水力失調(diào)等問題,進(jìn)行針對(duì)性的研究；建立水力分析數(shù)學(xué)模型,對(duì)主管網(wǎng)和大型分支進(jìn)行水力計(jì)算,結(jié)合水力計(jì)算的結(jié)論對(duì)供熱管網(wǎng)進(jìn)行針對(duì)性的技術(shù)改造嘗試,在完成水力平衡調(diào)整工作之后依靠大發(fā)供熱公司調(diào)度平臺(tái)的運(yùn)行數(shù)據(jù),在充分考慮民生效應(yīng)的前提下,得出各換熱站最佳流量分配表,為第二年供暖季的調(diào)網(wǎng)工作提供便利。
[Abstract]:In recent years, the air environment has continued to deteriorate, haze, dust weather has increased the number of times, the government is increasing investment in the control of air pollution every year, several air pollution indicators, such as total suspended particles, dust, sulfur dioxide, nitrogen oxides, The north city is higher than the southern city, the heating period is more serious than the non-heating period. During heating period, the air pollution index of the city generally exceeds the standard, and the basic reason is the pollutants released by heating coal. In the future, more and more heating buildings will release more pollutants and worse environmental indicators. Therefore, one of the important measures to improve air quality is to develop urban central heating. This paper will expound in detail the deep connection between heat source and heating operation, so that more people engaged in central heating can consider the problem from a new angle, and provide more people with reference in operation experience. First of all, this paper will discuss the advantages and disadvantages of multi-heat source centralized heating system, according to the actual situation of Dalian City, determine a kind of operation mode, combined with the actual operation of Dalian Dafa heating Company pipe network. The optimal operation mode of the pipe network, the distribution of high temperature water flow of heat load and the hydraulic maladjustment in operation are studied, and the mathematical model of hydraulic analysis is established, and the hydraulic calculation of the network and the large branch is carried out. Combined with the conclusion of hydraulic calculation, this paper attempts to carry out targeted technical transformation of the heating network. After completing the hydraulic balance adjustment, it relies on the operation data of the dispatching platform of Dafa heating Company, under the premise of fully considering the effect of people's livelihood. The optimal flow distribution table of each heat exchange station is obtained, which is convenient for the second heating season.
