【摘要】：對工業(yè)廢油(廢機油、廢液壓油、廢重油、液壓油、機械油、內(nèi)燃機油、汽輪機油等)的處理,主要是隨意扔棄或作為燃料,這兩種方式都會引起水和大氣等環(huán)境污染。但從經(jīng)濟價值的角度來看,廢油回收利用具有重大的潛在經(jīng)濟價值�，F(xiàn)有的廢油處理設(shè)備主要是采用再生凈化方式,廢油處理設(shè)備中又由眾多系統(tǒng)組成,其中就需要冷凝系統(tǒng)對凈化后的油液進行冷凝處理。已有冷凝技術(shù)主要采用水冷、風(fēng)冷、強制冷凝等方式,這些冷凝系統(tǒng)仍存在許多問題,那么開展廢油資源化設(shè)備的強制冷凝技術(shù)研究尤為重要。本文基于渦旋通用型線的完整理論,對以形腔容積變化為工作原理的機械設(shè)備和通過共軛曲線進行傳動裝置的廓線理論進行研究,從提高壓縮效率、減少能源消耗、降低噪音污染方面開展廢油裝備冷凝技術(shù)的研究。 本文所做的主要工作如下: 1.基于泛函通用渦旋型線研究影響渦旋壓縮機整機性能的因素,對影響整機性能的關(guān)鍵部件,動、靜渦旋盤的四個基本參數(shù)進行氣體力分析。利用MATLAB的遺傳算法工具分析動、靜渦盤上的力、力矩與參數(shù)的關(guān)系,獲得了參數(shù)值的約束范圍,得到四個基本參數(shù)與力總體上呈現(xiàn)線性關(guān)系結(jié)論,并用實例計算驗證了約束范圍的有效性。 2.取泛函通用渦旋型線的特殊渦旋型線構(gòu)成的渦旋壓縮機,利用非劣排序遺傳算法(NSGA_II)對通用渦旋壓縮機的動靜渦旋盤渦旋體基本參數(shù)進行優(yōu)化設(shè)計,使渦旋盤受到的力、力矩、能效比EER達到最優(yōu)。較之其它優(yōu)化方法,NSGA_II能較好解決多目標(biāo)非線性優(yōu)化問題,最后用優(yōu)化后的數(shù)據(jù)驗證了該方法的有效性。 3.利用MATLAB軟件得到通用渦旋型線的基礎(chǔ)空間點數(shù)據(jù),接著利用PRO/ENGINEER(Pro/ E)軟件參數(shù)化特征造型技術(shù)進行渦旋壓縮機零部件的三維建模,并對其零部件進行裝配和干涉檢查。 4.取泛函通用渦旋型線研究渦旋制冷壓縮機性能,利用MATLAB軟件編程,得到關(guān)于切向角參數(shù)φ的相應(yīng)空間坐標(biāo),接著利用Pro/ E軟件對部件進行三維建模,然后在Pro/ E的ASSEMBLY模塊下進行裝配,在設(shè)定的變頻與定頻兩種驅(qū)動模式下對機構(gòu)模塊中進行仿真分析,分析得出了變頻驅(qū)動下壓縮機的工況優(yōu)勢。
[Abstract]:The treatment of industrial waste oil (waste oil, waste hydraulic oil, waste heavy oil, hydraulic oil, mechanical oil, internal combustion engine oil, turbine oil, etc.) is mainly discarded or used as fuel, Both of these methods can cause environmental pollution, such as water and atmosphere. But from the point of view of economic value, the recovery and utilization of waste oil has great potential economic value. The waste oil treatment equipment is composed of many systems, among which the condensing system is needed to condensate the purified oil. The existing condensing technology mainly adopts water cooling, air cooling, forced condensation and so on, and there are still many problems in these condensing systems. So it is particularly important to develop the research on forced condensation technology of waste oil recycling equipment. This paper is based on the complete theory of vortex general profile. Based on the working principle of the volume change of the shape cavity and the profile theory of the transmission device through the conjugate curve, this paper studies the theory of the profile of the transmission device, in order to improve the compression efficiency and reduce the energy consumption. Research on condensing technology of waste oil equipment for reducing noise pollution. The main work of this paper is as follows:. 1. Based on the functional general vortex profile, the factors affecting the performance of the scroll compressor are studied, and the gas force analysis of the four basic parameters of the key components, the moving and the static vortex disk, is carried out. The movement is analyzed by the genetic algorithm tool of MATLAB. The constraint range of parameter value is obtained by the relationship between force, moment and parameter on the static vortex disk. The conclusion that the four basic parameters and the force are linear in general is obtained. The validity of the constraint range is verified by an example. 2. Taking the vortex compressor which is composed of the special vortex line of the functional general vortex line, using the noninferior sorting genetic algorithm (NSGA II) to optimize the basic parameters of the vortex body of the general scroll compressor, the force and torque of the scroll disk are obtained. Compared with other optimization methods, EER II can solve the multi-objective nonlinear optimization problem. Finally, the validity of the method is verified by the optimized data. 3. The basic spatial point data of the general vortex profile are obtained by using MATLAB software, and then the 3D modeling of the parts of the scroll compressor is carried out by using the parametric feature modeling technology of PROP / E software, and the assembly and interference inspection of the parts are carried out. 4. The functional general vortex profile is used to study the performance of the scroll refrigeration compressor. The corresponding spatial coordinates of tangential angle parameter 蠁 are obtained by using MATLAB software, and then the 3D modeling of the components is carried out by using ProE software. Then the assembly is carried out under the ASSEMBLY module of ProE, and the simulation analysis of the mechanism module is carried out under the two driving modes of frequency conversion and constant frequency, and the advantages of the compressor driven by frequency conversion are obtained.
