【摘要】：絕大部分工廠都需要使用空氣壓縮機壓縮空氣,空壓機在壓縮空氣過程中會產(chǎn)生大量的熱量,導(dǎo)致壓縮空氣溫度升高。在傳統(tǒng)的使用過程中,往往為了滿足空壓機工作要求需要配備循環(huán)冷卻水或者冷凍水對壓縮空氣進行熱交換進行冷卻來保證其穩(wěn)定運行,同時產(chǎn)生的這部分熱量直接被排放到大氣中去。這不僅損失了大量的熱能同時還造成了生產(chǎn)冷卻水或冷凍水的電耗量大幅度上升。為了回收這部分熱量同時減少制冷系統(tǒng)的能量消耗,以一個現(xiàn)有的具有空壓站的一個工廠為例,通過理論分析與實際研究介紹了一種余熱回收技術(shù),通過在原有空壓機冷卻系統(tǒng)的基礎(chǔ)上加以改造,在空壓機壓縮后的出口管道上安裝三通閥,增加一套冷卻系統(tǒng)和換熱系統(tǒng),并實現(xiàn)冷卻水溫度以及冷卻水量的自動控制,在不影響空壓機正常運行的情況下將空壓機壓縮空氣做功產(chǎn)生的熱量代替用于其它工藝中需要的用于給原水加熱的能源,從而減少了用于空壓機冷卻以及生產(chǎn)工藝加熱的能耗,同時在原有空壓機冷卻系統(tǒng)的基礎(chǔ)上加以改造,減少一部分冷卻系統(tǒng)的使用量以達(dá)到減少了冷卻系統(tǒng)的能耗的目的。并結(jié)合現(xiàn)場調(diào)研和對系統(tǒng)節(jié)能運行評估手段,計算得出了此種余熱利用技術(shù)的節(jié)能效果,并研究出此種余熱回收效益的一般計算方法,同時對工業(yè)壓縮空氣系統(tǒng)中目前存在的新興的節(jié)能技術(shù)的特點及應(yīng)用范圍進行了分析和探討,為今后在此基礎(chǔ)上開展的合同能源管理模式奠定了技術(shù)基礎(chǔ),為企業(yè)進行節(jié)能改造提供了理論依據(jù)。具有良好的經(jīng)濟和社會效益。
[Abstract]:Most factories need to use compressed air compressor, air compressor in the process of compressed air will produce a lot of heat, resulting in compressed air temperature rise. In the traditional use process, in order to meet the operational requirements of the air compressor, it is often necessary to provide circulating cooling water or refrigerated water to cool the compressed air for heat exchange to ensure its stable operation. This part of the heat generated at the same time is emitted directly into the atmosphere. This not only loses a lot of heat energy, but also increases the power consumption of cooling water or freezing water. In order to recover this part of heat and reduce the energy consumption of refrigeration system, a waste heat recovery technology is introduced through theoretical analysis and practical research, taking an existing plant with an air pressure station as an example. On the basis of the original cooling system of the air compressor, the three-way valve is installed on the compressed outlet pipeline of the air compressor, a set of cooling system and heat exchange system are added, and the cooling water temperature and the cooling water quantity are automatically controlled. Without affecting the normal operation of the air compressor, the heat generated by the work done by the compressed air of the air compressor is replaced by the energy used to heat the raw water needed in other processes, thus reducing the energy consumption for the cooling of the air compressor and the heating of the production process. At the same time, on the basis of the original cooling system of air compressor, the amount of cooling system is reduced to reduce the energy consumption of the cooling system. Combined with field investigation and evaluation of energy saving operation of the system, the energy saving effect of the waste heat utilization technology is calculated, and the general calculation method of the efficiency of the waste heat recovery is also studied. At the same time, the characteristics and application scope of the emerging energy-saving technology in the industrial compressed air system are analyzed and discussed, which will lay a technical foundation for the contract energy management mode to be carried out in the future. It provides the theoretical basis for the enterprise to carry on the energy saving transformation. It has good economic and social benefits.
