漳州長泰移動螺桿空壓機(jī)租賃 工業(yè)廢熱回收利用大面廣,使用技術(shù)的方式,設(shè)備眾多,但也有一些合適的條件下,應(yīng)該根據(jù)不同類型的企業(yè)剩余熱量,溫度、熱量、結(jié)合生產(chǎn)條件、工藝流程、內(nèi)部和外部的能源需求,選擇適當(dāng)?shù)睦糜酂?從而實(shí)現(xiàn)降低能耗的目的,提***率。例如:余熱梯度利用技術(shù)，從熱力學(xué)的角度來看，能源經(jīng)過多次使用，會產(chǎn)生損耗，因此，使用的***終會顯得效率低下，但當(dāng)冷熱負(fù)荷條件存在時，余熱梯度的利用是非常必要的。

Industrial waste heat recovery has a wide range of uses, technology and equipment, but there are also some suitable conditi***, according to different types of enterprise residual heat, temperature, heat, combined with production conditi***, process flow, internal and external energy demand, choose appropriate use of waste heat, so as to achieve the purpose of reducing energy c***umption and improving efficiency. For example, the technology of waste heat gradient utilization, from the thermodynamic point of view, energy will be lost after many times of use, therefore, the ultimate use will appear inefficient, but when the cold and heat load conditi*** exist, the utilization of waste heat gradient is very necessary.
廢熱回收和利用是循環(huán)的過程中包含的熱能氣態(tài)(如高溫?zé)煔?、液態(tài)(如冷卻水)和固體(如各種耐高溫鋼產(chǎn)品)在工業(yè)生產(chǎn)過程中排放高于環(huán)境溫度,并利用它。據(jù)統(tǒng)計(jì)，我國工業(yè)能源消費(fèi)約有50%是不使用的，而是直接以各種形式浪費(fèi)的余熱，回收率高達(dá)60%以上。我國余熱資源平均回收率僅為30%左右，落后于***水平10~20個百分點(diǎn)。
Waste heat recovery and utilization is the process of recycling, including heat energy gaseous (such as high temperature flue gas), liquid (such as cooling water) and solid (such as various high temperature steel products) in the industrial production process emissi*** higher than the environmental temperature, and use it. According to statistics, about 50% of China's industrial energy c***umption is not used, but waste heat directly in various forms, the recovery rate is as high as 60%. The ***erage recovery rate of waste heat resources in China is only about 30%, which lags behind the international advanced level by 10 to 20 percentage points.

回收余熱的方法有很多。綜合利用余熱效果***好;其次,直接利用;第三種是間接利用(用蒸汽發(fā)電)。同時，不同質(zhì)量和工藝要求的能源也不同。在這種情況下，企業(yè)應(yīng)因地制宜，提前進(jìn)行能耗分析和能源體系評價。在實(shí)踐中，一些企業(yè)沒有按照這些原則認(rèn)真分析，難以取得良好的效果。例如:有的企業(yè)高溫焦炭余熱不回收，而是在使用低溫低壓余熱;一些企業(yè)利用煤矸石發(fā)電，而優(yōu)質(zhì)煤炭尚未開采。高質(zhì)量的能源沒有得到充分利用，所以我們在追求低質(zhì)量的熱的利用，而低質(zhì)量的熱的利用是沒有效率的。
There are many ways to recover waste heat. Comprehensive utilization of waste heat has the best effect; secondly, direct utilization; the third is indirect utilization (steam power generation). At the same time, different quality and process requirements of energy are also different. In this case, enterprises should make energy c***umption analysis and energy system evaluation in advance according to local conditi***. In practice, some enterprises h***e not carefully analyzed these principles, and it is difficult to achieve good results. For example, some enterprises do not recycle high-temperature coke waste heat, but use low-temperature and low-pressure waste heat; some enterprises use coal gangue to generate electricity, while high-quality coal has not yet been mined. High-quality energy is not fully utilized, so we are pursuing low-quality heat utilization, and low-quality heat utilization is inefficient.
目前，在高耗能行業(yè)，新建裝配線余熱發(fā)電空間有限，整個行業(yè)都面臨產(chǎn)能過剩的問題，因此，開發(fā)相應(yīng)的余熱利用是必不可少的。高能耗企業(yè)需要從政策導(dǎo)向轉(zhuǎn)向自我導(dǎo)向，提高經(jīng)濟(jì)效益，選擇合適的余熱回收利用方式。
