Abstract
The invention discloses a sunshading water cooling device which comprises a vacuum buffer tank 1, wherein a sunshading sheath 2 is arranged on an outer cover of the vacuum buffer tank 1; and a spray head 3 connected with cooling water is arranged between the sunshading sheath 2 and the vacuum buffer tank 1. The surface temperature of the vacuum buffer tank can be controlled within a relatively ideal range, so that light components in the vacuum buffer tank can be condensed in time, the system vacuum degree can be improved, and higher rectification efficiency can be obtained.
Description
Technical field
The present invention relates to technical field of chemical, be specifically related to a kind of sunshade water-cooled 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 light component such as the low-carbon (LC) organic matter that cat head is distilled and glycerine carries out condensation and collection.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 a jar interior light component then is difficult to condensation, and the gas phase residual voltage is higher, and degree of vacuum descends, and finally influences rectification under vacuum efficient.
As far as the vacuum buffer tank temperature controlling, the hot weather in summer is an important disturbance factor often.Be exposed to outdoor expansion tank, mostly its material 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 when light and temperature spread backlight maximum nearly 25 ℃.Under the sunshine strong situation; The vacuum buffer tank receives sunlight direct projection temperature higher; The interior recirculated cooling water of jar can not effectively distillate the light component condensation to cat head and get off, and remaining gaseous phase partial pressure seriously reduces the system vacuum degree, and then the system vacuum degree is descended; Cause the rectifying separation temperature build-up, separation efficiency reduces can not carry out the actv. separation even.
Summary of the invention
The technical matters that the present invention will solve provides a kind of sunshade water-cooled cooling device; Can be the surface temperature control of vacuum buffer tank in more satisfactory scope; Make the light component condensation in time 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 present invention adopts following technical scheme:
Sunshade water-cooled 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, said sunshade cover is the support that the bowl of a surface coverage aluminium skin is buckled shape.Said aluminium skin is that the aluminium skin is used in the common insulation of chemical field.Between sunshade cover and the vacuum buffer tank, need leave certain space, guaranteeing effect of heat insulation and to be convenient to install shower nozzle, 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, said shower nozzle should be located on the vacuum buffer tank top.Simultaneously, shower nozzle be provided with downward, oblique down, horizontal direction and the spray orifice of four direction obliquely; Wherein, downwards be used for the cooling of expansion tank spray, and horizontal direction and spray orifice obliquely are used for the spray that sunshade overlaps and cool off with oblique spray orifice down.
The invention has the beneficial effects as follows:
1, the present invention can effectively control 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 present invention makes light component be easy to condensation when reducing the vacuum buffer tank surface temperature, avoids a large amount of light component to get into water-ring vacuum pump equal vacuum equipment, has reduced the loss of light component.
3, contain 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 get into water-ring vacuum pump equal vacuum system equipment in a large number, make the circulating water acidifying, and then cause that the pump housing and circulating water delivery duct corrode.

Label is among the figure: 1, vacuum buffer tank, 2, the sunshade cover, 3, shower nozzle, 4, water valve.
The specific embodiment
Below the preferred embodiments of the present invention are described, should be appreciated that preferred embodiment described herein only is used for explanation and explains the present invention, and be not used in qualification the present invention.
As illustrated in fig. 1 and 2, sunshade water-cooled 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 said 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 that the aluminium skin is used in insulation common in the Chemical Manufacture, has light, the easy moulding of weight, withstanding corrosion and heat insulation good advantage.The spacing that 2 inside faces and vacuum buffer tank 1 outside face are overlapped in said sunshade is 20cm, reserving certain space, thereby guarantees the installation of effect of heat insulation and shower nozzle 2.Said shower nozzle 2 is located on vacuum buffer tank 1 top; It is provided with downward, oblique down, horizontal direction and the spray orifice of four direction obliquely; Downwards be used for the cooling of expansion tank spray, and horizontal direction and spray orifice obliquely are used for sunshade and overlap 2 spray and cool off with oblique spray orifice down.Shower nozzle 2 is communicated with through pipeline and the recirculated cooling water that is used in the vacuum buffer tank 1, shower nozzle 2 can conveniently be installed like this and shorten to connect the used pipeline of shower nozzle 2; Be provided with water valve 4 with shower nozzle 2 bonded assembly pipelines, with control shower nozzle 2 foldings and injection flow rate.
On the daytime lower with temperature at night, that sunshine is more weak, 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; Look vacuum buffer tank 1 surface temperature situation of change; Open the water valve 4 of shower nozzle 2 at regular intervals; With cooling water expansion tank the aluminium skin and the tank surface of sunshade cover 2 are lowered the temperature, thereby realization reduces the surface temperature of vacuum buffer tank 1, its temperature is controlled at the purpose of suitable range of temperatures.
