Abstract
The utility model discloses a kind of device for benzene dehydration, comprise the first dehydrator, the second dehydrator, the 3rd dehydrator and the benzene holding vessel that connect successively; The bottom of the first described dehydrator, the second dehydrator and the 3rd dehydrator is provided with drainpipe, and its outside is provided with chuck, first dehydrator is connected cooling water inlet pipe road with the below of the chuck of the second dehydrator, top connects CWR road, the below of the chuck of the 3rd dehydrator connects chilled water inlet channel, and top connects chilled water water return pipeline.The utility model, on the basis of existing distillation dehydration, decreases energy resource consumption, greatly reduces raw-material loss, and environmentally safe have very large lifting.And whole removal process can complete automatically, without the need to human users, greatly reduce cost of labor.
Description
Technical field
The utility model relates to chemical field, is specially a kind of device for benzene dehydration.
Background technology
At present, benzene is used to do in raw material or solvent production technology, in the recovery process of benzene, all adopt heating distillation dehydration method, make benzene and water simultaneously azeotropic steam, a then precipitation point water, come and go and carry out until by moisture to the greatest extent, consume the energy, in benzene evaporative condenser process, condensation effect is not good, significant loss, contaminated environment.In addition, benzene in continuous dewatering esterase still-process, due to constantly excessive, workshop benzene content is progressively increased, and benzene and air form mist, after reaching capacity, are easy to cause great chemical accident to occur, there is very large potential safety hazard.
Summary of the invention
The purpose of this utility model is for above problem, and provide a kind of device for benzene dehydration, effectively can dewater to benzene, its reasonable in design, dehydration cost is low, and working service is convenient.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of device for benzene dehydration, comprises the first dehydrator, the second dehydrator, the 3rd dehydrator and the benzene holding vessel that connect successively; The bottom of the first described dehydrator, the second dehydrator and the 3rd dehydrator is provided with drainpipe, and its outside is provided with chuck, first dehydrator is connected cooling water inlet pipe road with the below of the chuck of the second dehydrator, top connects CWR road, the below of the chuck of the 3rd dehydrator connects chilled water inlet channel, and top connects chilled water water return pipeline.
Described drainpipe is provided with valve; After the moisture of device bottom to be drained off depositing dosed quantities, Open valve discharges, and can save the working time, reduces production cost.
Described cooling water inlet pipe road, CWR road, chilled water inlet channel and chilled water water return pipeline are all provided with valve, according to the ducted discharge of how many controls of water content in benzene, strengthen outlet effect.
This device is also provided with cooling water water tank and chilled water water tank, and the water temperature wherein in cooling water water tank is 30 ± 3 DEG C, and the water temperature in chilled water water tank is 15 ± 1 DEG C.
The utility model adopts said structure design, and by arranging two-stage cooling water condensation dehydrator and one-level cooling water lyophilization device, the moisture that can thoroughly go out in benzene, reaches its relevant criterion and requirement completely.Reasonable in design of the present utility model, easy to operate, this device does not need to add hot reflux, and benzene number of dropouts is little, and reduce environmental pollution, whole process is carried out under low-temperature condition, reduces equipment corrosion, and the service life of extension device.
The utility model, on the basis of existing distillation dehydration, decreases energy resource consumption, greatly reduces raw-material loss, and environmentally safe have very large lifting.And whole removal process can complete automatically, without the need to human users, greatly reduce cost of labor.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Further illustrate the utility model below in conjunction with embodiment, but the claimed scope of the utility model is not limited to the scope of embodiment statement.
As shown in Figure 1, a kind of device for benzene dehydration, comprises the first dehydrator 1, second dehydrator 2, the 3rd dehydrator 3 and the benzene holding vessel 4 that connect successively; The first described dehydrator 1, second dehydrator 2 and the bottom of the 3rd dehydrator 3 are provided with drainpipe, and its outside is provided with chuck, first dehydrator 1 is connected cooling water inlet pipe road with the below of the chuck of the second dehydrator 2, top connects CWR road, the below of the chuck of the 3rd dehydrator 3 connects chilled water inlet channel, and top connects chilled water water return pipeline.
Further, described drainpipe is provided with valve.
Further, described cooling water inlet pipe road, CWR road, chilled water inlet channel and chilled water water return pipeline are all provided with valve.
Further, this device is also provided with cooling water water tank and chilled water water tank, and the water temperature wherein in cooling water water tank is 30 ± 3 DEG C, and the water temperature in chilled water water tank is 15 ± 1 DEG C.
During use, the azeotropic mixture of benzene and water is entered this device by the first dehydrator, by chuck, condensation is carried out to it, according to difference of specific gravity and the dissolubility of water in benzene of benzene and water, the lower moisture content of temperature dissolves fewer, during condensation, water is progressively deposited to the bottom of dehydrator, can discharge from bottom, and the second dehydrator and and the 3rd dehydrator can remove moisture wherein further, particularly the 3rd dehydrator, due to employing is chilled water, more easily promote the taking-up of water, finally reach the effect removing moisture in benzene completely, dewatered benzene can be collected in benzene holding vessel.
