Abstract
The utility model discloses a sun shading water cooling device which comprises a vacuum buffering tank (1), a sun shading sleeve (2) is covered on the vacuum buffering tank (1) and a nozzle (3) connected with cooling water is arranged between the vacuum buffering tank (1) and the sun shading sleeve (2). The sun shading water cooling device controls the temperature of the surface of the vacuum buffering tank within an ideal range so that light components in the vacuum buffering tank can be congealed in a timely mode, a vacuum degree of a system is improved and high rectification efficiency is obtained.
Description
Technical field
The utility model relates to technical field of chemical, is specifically related to a kind of sunshade water-cooling cooling device.
Background technology
In production of biodiesel, adopt rectification under vacuum to carry out the separation of intermediate product more.Yet rectification under vacuum must be added a vacuum buffer tank at the rectification column top, is used for the buffering to vacuum system, and the light component such as the low-carbon (LC) organic matter that cat head is distilled and glycerine carry out condensation and collect.Therefore, the temperature of vacuum buffer tank directly affects the condensation effect of light component; If the vacuum buffer tank temperature is higher than 45 ℃, then light component then is difficult to condensation in the tank, and the gas phase residual voltage is higher, and degree of vacuum descends, and finally affects rectification under vacuum efficient.
For the control of vacuum buffer tank temperature, the hot weather in summer is an important disturbance factor often.Be exposed to outdoor expansion tank, its material mostly is corrosion-resistant steel, and as easy as rolling off a log heat absorption is conducted heat, and the tank surface temperature that directly shone by sunlight can reach 60～65 ℃, tank surface during to light and temperature spread backlight maximum nearly 25 ℃.In the sunshine strong situation, the vacuum buffer tank is subjected to the direct sunlight temperature higher, the interior recirculated cooling water of tank can not effectively distillate the light component condensation to cat head and get off, remaining gaseous phase partial pressure seriously reduces the system vacuum degree, and then the system vacuum degree is descended, cause the rectifying separating temperature to raise, separation efficiency reduces can not carry out even the actv. separation.
The utility model content
The technical problems to be solved in the utility model provides a kind of sunshade water-cooling cooling device, can be the surface temperature control of vacuum buffer tank in more satisfactory scope, make the in time condensation of light component in the vacuum buffer tank, improve the system vacuum degree, to obtain higher rectification efficiency.
For solving the problems of the technologies described above, the utility model by the following technical solutions:
The sunshade water-cooling cooling device comprises vacuum buffer tank, is covered with a sunshade cover at vacuum buffer tank, is provided with the shower nozzle of a connection cooling water expansion tank between this sunshade cover and the vacuum buffer tank.
In the such scheme, described sunshade cover is the support that the bowl of a surface coverage aluminium skin is buckled shape.Described aluminium skin is the common insulation of chemical field aluminium skin.Between sunshade cover and the vacuum buffer tank, need leave certain space, guaranteeing effect of heat insulation and to be convenient to mounting spray head, be not less than 20cm with the spacing of sunshade cover inside face and vacuum buffer tank outside face and be advisable.
In the such scheme, described shower nozzle should be located on the vacuum buffer tank top.Simultaneously, shower nozzle is provided with downward, oblique lower, horizontal direction and the spray orifice of four direction obliquely; Wherein, downwards and oblique lower spray orifice be used for the expansion tank spraying cooling, and the spraying cooling that horizontal direction and spray orifice obliquely overlap for sunshade.
The beneficial effects of the utility model are:
1, the utility model can effectively be controlled the surface temperature of vacuum buffer tank, and the light component that the rectification under vacuum top of tower is distilled out is easy to condensation, reduces the gas phase residual voltage, improves the system vacuum degree.
2, the utility model makes light component be easy to condensation when reducing the vacuum buffer tank surface temperature, avoids a large amount of light component to enter water-ring vacuum pump equal vacuum equipment, has reduced the loss of light component.
3, contain the acidic materials such as a small amount of low carbon chain carboxylic acid, aldehyde, phenol in the light component, its condensation is in vacuum buffer tank, can avoid acidic materials to enter in a large number water-ring vacuum pump equal vacuum system equipment, make the circulating water acidifying, and then cause the pump housing and circulating water delivery duct corrosion.
Description of drawings
Fig. 1 is the schematic diagram of the utility model sunshade water-cooling cooling device.
Fig. 2 is the structural representation of sunshade cover of the present utility model.
Number in the figure is: 1, vacuum buffer tank, 2, the sunshade cover, 3, shower nozzle, 4, water valve.
The specific embodiment
Below preferred embodiment of the present utility model is described, should be appreciated that preferred embodiment described herein only is used for description and interpretation the utility model, and be not used in restriction the utility model.
As illustrated in fig. 1 and 2, the sunshade water-cooling cooling device comprises vacuum buffer tank 1, is covered with sunshade cover 2 at vacuum buffer tank 1, is provided with the shower nozzle 2 of a connection cooling water expansion tank between this sunshade cover 2 and the vacuum buffer tank 1.Wherein, the main body of described sunshade cover 2 is the support of one bowl of button shape, and it is the aluminium skin of 0.5mm that the surface coverage of this support has a layer thickness; Used aluminium skin is insulation common in Chemical Manufacture aluminium skin, has advantages of light, the easy moulding of weight, withstanding corrosion and heat insulation good.The spacing that 2 inside faces and vacuum buffer tank 1 outside face are overlapped in described sunshade is 20cm, reserving certain space, thereby guarantees the installation of effect of heat insulation and shower nozzle 2.Described shower nozzle 2 is located on vacuum buffer tank 1 top, it is provided with downward, oblique lower, horizontal direction and the spray orifice of four direction obliquely, spray orifice under downward and oblique is used for the expansion tank spraying cooling, and horizontal direction and spray orifice obliquely are used for the spraying cooling of sunshade cover 2.Shower nozzle 2 is communicated with by pipeline and the recirculated cooling water that is used in the vacuum buffer tank 1, can make things convenient for like this mounting spray head 2 and shorten to connect the used pipeline of shower nozzle 2; The pipeline that connects of being connected with shower nozzle is provided with water valve 4, with control shower nozzle 2 foldings and injection flow rate.
At night weak daytime at, sunshine lower with temperature, the surface temperature of vacuum buffer tank 1 is lower, the processing of spraying water of the water valve 4 of generally not opening shower nozzle 2.And at fine, sunshine when violent, depending on vacuum buffer tank 1 surface temperature situation of change, open at regular intervals the water valve 4 of shower nozzle 2, with cooling water expansion tank aluminium skin and the tank surface of sunshade cover 2 are lowered the temperature, thereby realize reducing the surface temperature of vacuum buffer tank 1, its temperature is controlled at the purpose of suitable range of temperatures.
