精炼设备;精炼油设备中为什么要用水化脱胶,水化脱胶有什么特点
水化脱胶作为毛油精粹中重要的技术,需要用的首要精粹油设备按技术效果可分为水化器、别离器及枯燥器等,按出产的连贯性又可分为间歇式和接连式。下面,小编精粹油设备水化脱胶的首要设备及效果为我们解析如下:
Hydration degumming as essence of crude oil is an important technology, need to use the primary essence oil equipment according to the technical effect can be water device, parting and boring device etc., according to the production of coherence can be divided into intermittent and series type. The following, primary equipment and effects of small oil degumming essence of equipment for our analysis are as follows:
1、精粹油设备水化罐
1, the essence of oil equipment of water tank
水化罐是间歇式水化脱胶的首要精粹设备,它与沉降别离水化油脚的沉降罐构造类似。通常工厂考虑到出产的周转,通常装备两只以上,水化罐和沉降罐可彼此通用。
The water tank is the primary essence of equipment of intermittent water degumming, which is similar with the tectonic subsidence and sedimentation tank were hydrated. Usually the factory takes into account the turnover of production, usually equipped with two or more, the water tank and the settlement tank can be common to each other.
水化罐即通常通称的炼油锅。其主体是一个带有锥形底的短圆筒体,罐轴线上设有桨叶式拌和器,在拌和器轴上装有2~4对桨叶式拌和翅,接近锥形底处装有一对异型拌和翅。拌和器由设备于罐顶的传动设备传动,依据技术请求,通常设有快、慢两档速度。
The water tank is usually oil pot known as. The main body is a short cylindrical body with a conical bottom, with a paddle type mixer on the axis of the tank, with 2 ~ 4 on the axis of the mixing device, and a pair of special shaped mixing fins are arranged on the conical bottom. The mixer is driven by the transmission device of the tank top. According to the technical request, the mixer is usually equipped with a fast and slow two speed.
在接近罐壁内缘处,设备着加热用的间接蒸汽笼管(也有用盘管的)。加热管与冷水管相通,可以通入冷水冷却罐内的油。在锥形底部设有一圈直接蒸汽喷管,从蒸汽进入端起,由疏到密开有下斜喷孔,孔洞直径通常为1.52 mm,孔间间隔为75~100 mm。在水化罐罐壁上部有进油管,水化罐盖的下部,设备着一圈加水管(e),用来加注水化用的水或别的溶液。
Close to the tank wall at the inner edge of the equipment, with indirect steam heating in the cage tube (also useful coil). The heating pipe is communicated with the cold water pipe and can be connected with the oil in the cold water cooling tank if necessary. At the bottom of the cone with a circle of direct steam nozzle, from the steam into the end, from sparse to dense open oblique nozzle hole, hole diameter usually 1.5-2 mm, hole interval is from 75 to 100 mm. In the upper part of the water tank wall is provided with an oil pipe, the lower part of the water tank cover, and a ring of water (E), which is used to fill the water or other solution.
水化罐锥底部,装有排放油脚用的截门(j)。笼罐(或盘管)加热设备的水化罐在沉降别离时,加热设备上会拦积一部分水化油脚,影响传热功率和油品质量。因此,沉降别离水化油脚时选用夹套加热的沉降罐。
The water tank is equipped with a discharging cone at the bottom, with a foot (J). Cage or coil heating device of the water tank in settling separation, heating equipment will stop product part of the water sediment, the effects of heat power and oil quality. Therefore, the best choice of settling tank jacket heating settlement hydrated when parting.
2、精粹油设备接连水化器
2, the essence of water for oil equipment series
接连水化器的构造比较简略,只要能确保粗油在接连活动的情况下完成水化进程,水化器可规划成多种形式。如上图以盐水水化的接连水化设备,由蒸汽喷发器和水化罐构成。蒸汽喷发器的技术效果首要是引射粗油和水化用的盐水,并使其在混合腔瞬时剧烈混合射入水化罐。
The structure of a series of water is simple, so long as it can ensure that the crude oil in the case of a series of activities to complete the process of hydration, hydration can be planned into a variety of forms. In the case of a series of water, water, water, water, water, water, equipment, by the steam and the water tank. The technical effect of the steam injector is mainly caused by the injection of crude oil and water, and to make it into a water tank in a mixed chamber.
水化罐为附夹套加热的空罐体,技术效果是供给停留时刻,使胶粒充沛凝聚。其间以直接蒸汽水化的接连水化器。设有蒸汽鼓泡器和蒸汽喷发循环设备,构造简略,操作便利。除此之外,接连碱炼的比配及混合设备也可用作接连水化,但需接絮凝罐,以确保水化效果好。
The water tank is empty of tank jacket heating technology, the effect is the supply of residence time, make plenty of condensed particles. In the process of direct steam to the water of a series of water. It is equipped with steam drum device and steam explosion cycle equipment, the structure is simple and easy to operate. In addition, a series of alkali refining of proportioning and mixing equipment can also be used as a series of hydration, but need to be connected with the flocculation tank, to ensure that the hydration effect completely.
3、精粹油设备枯燥器
3, the essence of oil equipment boring device
枯燥器是专用于水化(或碱炼)净油脱除残留水分的设备。按工作的连贯性可分为间歇式和接连式,按工作工作状态又可分为常压式和减压式。接连式枯燥器是在减压条件下工作的脱水设备。各种形式的真空枯燥器构造类似,都由圆筒壳体、进油喷头、别离挡板和折流板等主件构成。
The device is dedicated to water (or alkaline) net oil removal of residual water equipment. According to the continuity of the work can be divided into intermittent and successive, according to the work of the state can be divided into normal pressure and pressure type. A series of boring machine is the dehydration equipment under the condition of reducing pressure. Various forms of vacuum boring machine structure similar, are composed of a cylindrical shell, into the oil nozzle, the main parts of the baffle and baffle plate.
如真空枯燥器是一种降膜式脱水设备。该设备利用流体喷发反冲力,使喷头发生转动惯量而高速旋转。含水油脂在流体速度头和离心力场下,高速射溅呈雾滴和沿筒壁呈膜状降低过程中得到枯燥。
Such as vacuum drying device is a kind of falling film type dewatering equipment. The device uses fluid eruption recoil inertia, the occurrence of nozzle to rotate at high speed. Water cut oil in the velocity head and the centrifugal force field, high speed sputtering a droplet and along the tube wall is membranous reduced by boring.
4、精粹油设备脱溶器
4, the essence of oil equipment stripping device
脱溶器是专用于水化(或碱炼)浸出油脱除残留溶剂的设备。按工作的连贯性可分为间歇式和接连式。接连式脱溶器构造如上图所示。首要由一个中心工作室和6个周围工作室构成。
The stripping device is a device for removing the residual solvent from the water (or alkali refining) leaching oil. According to the continuity of the work can be divided into intermittent and continuous type. A series of the type of the structure of the solution is shown in the picture above. First by a central studio and 6 around the studio constitute.
每个工作室内均设有直接蒸汽喷管、油循环和加热设备,各工作室经过溢流孔(或溢流管)构成连工作通道。接连脱溶器的工作条件需满意如下请求:温度140℃,操作压力≤4.0kPa,油停留时刻≥30min。
Each workshop is equipped with a direct steam nozzle, oil circulation and heating equipment, the studio through the overflow hole (or overflow pipe) constitute a continuous working channel. After stripping the working conditions to meet the following requirements: 140 degrees Celsius temperature, operating pressure is less than 4.0kPa, more than 30min times for oil.
