Description

A kind of heavy constituent apparatus for regulating viscosity
Technical field
The utility model relates to a kind of devices, and more specifically, it relates to a kind of heavy constituent apparatus for regulating viscosity.
Background technique
In chemical production process, generallys use evaporator and carry out the operation such as component separation, purifying.But in actual mechanical process In, often there is the problems such as viscosity is excessively high, flow resistance is big in the component in evaporator, the remaining heavy constituent after causing evaporation cannot It can smoothly enter into next unit operation;The liquid level in evaporator adds up to increase simultaneously, is can lead to inside evaporator when serious not yet The liquid organic products of vaporization is sprayed from top safety valve, causes large-tonnage product loss and environmental pollution.
Currently, solve the problems, such as this measure be by improve evaporator outlet temperature, will accumulation liquid level fast vaporizing from The discharge of evaporator top exit;Although this method can reduce rapidly liquid level in a short time, long term high temperature operation can make it is some not Volatile substance (when such as prepared by octyl alconyl, triphenylphosphine etc.) in carbongl group synthesis reaction, evaporates damage from low pressure evaporator It loses, energy consumption cost also will increase, while also resulting in a large amount of heavy constituents and generating, and increase heavy constituent content sharply, finally Liquid level can not be made to reduce by evaporation, but catalyst is in the condition of high temperature due to long-time in heavy constituent, and gradually inactivates, it can only Catalyst change is carried out, catalyst cost allowance is caused, if more catalyst changeout makes process units stop again, seriously affects enterprise Economic benefit.
Utility model content
The purpose of this utility model is to overcome deficiencies in the prior art, provide a kind of weight that mating evaporator uses Compositional viscosity regulating device reduces heavy constituent viscosity, reduces its flow resistance in transfer pipeline, effectively prevent because of fluid The problems such as resistance equipment loss caused greatly, component loss.
The purpose of this utility model is achieved through the following technical solutions.
The outlet at bottom of a kind of heavy constituent apparatus for regulating viscosity of the utility model, including evaporator, the evaporator is logical It crosses pipeline and is connected with heat exchanger, the first valve, first circulation pump, first flowmeter, thinning tank, second circulation pump and reaction in turn Device, the thinning tank are also connected with second flowmeter, the second valve and organic solvent tank in turn by pipeline;The thinning tank Recombination subentry, organic solvent entrance and dilution outlet, the recombination subentry is offered on tank skin to go out with first flowmeter Mouth is connected, and the organic solvent entrance is connected with second flowmeter outlet, and the dilution outlet is pumped into second circulation Mouth is connected.
Equal portion is provided with blender in the thinning tank and reactor.
The organic solvent tank is using the organic solvent storage tank or the dedicated organic solvent of heavy constituent dilution on production line Tank.
The heavy constituent that organic solvent in the organic solvent tank is discharged with evaporator should dissolve each other.
Compared with prior art, beneficial effect brought by the technical solution of the utility model is:
The utility model overcomes the defect of the prior art, with of simple structure and low cost, safe and reliable, environment is friendly Well, the features such as good economical benefit, after the heavy constituent of evaporator exit is diluted by thinning tank, the viscosity of heavy constituent obviously drops It is low, be substantially reduced flow resistance of the heavy constituent in transfer pipeline, effectively prevent because fluid resistance greatly caused by equipment damage The problems such as consumption, component loss.
Detailed description of the invention
Fig. 1 is the attachment structure schematic diagram of the utility model.
Appended drawing reference: 1 evaporator;2 heat exchangers;3 first valves;4 first circulations pump;5 first flowmeters;6 thinning tanks;6a Recombinate subentry;6b organic solvent entrance;The outlet of 6c dilution;7 second circulations pump;8 reactors;9 organic solvent tanks;10 second Valve;11 second flowmeters;12 blenders.
Specific embodiment
The utility model will be further described with reference to the accompanying drawing.
As shown in Figure 1, a kind of heavy constituent apparatus for regulating viscosity of the utility model, including evaporator 1, the evaporator 1 Outlet at bottom by pipeline be connected in turn heat exchanger 2, the first valve 3, first circulation pump 4, first flowmeter 5, thinning tank 6, second circulation pumps 7 and reactor 8, is mounted on blender 12 inside the thinning tank 6 and reactor 8.The thinning tank 6 Recombination subentry 6a, organic solvent entrance 6b and dilution outlet 6c, the recombination subentry 6a and first are offered on tank skin The outlet of flowmeter 5 is connected, and the dilution outlet 6c pumps 7 entrances with second circulation and is connected, 7 outlet of second circulation pump It is connected with reactor 8 Deng.The organic solvent entrance 6b passes through pipeline from it outward and is connected with second flowmeter 11, second in turn Valve 10 and organic solvent tank 9, that is, the organic solvent entrance 6b are connected with the outlet of second flowmeter 11.It is described organic Solvent tank 9 can be the organic solvent storage tank on production line, is also possible to heavy constituent and dilutes dedicated organic solvent tank.It is described The heavy constituent that organic solvent in organic solvent tank 9 is discharged with evaporator 1 should dissolve each other.
The course of work of the present apparatus: the multicomponent mixtures such as catalyst, cymogene aldehyde are entered in evaporator 1 by pipeline, Under the set temperature of evaporator 1, pressure, the volatile components such as butyraldehyde in evaporator 1 are transferred out from 1 overhead line of evaporator It goes, remaining catalyst mixed component is after 1 bottom heat exchanger 2 of evaporator is cooling, under the draw of first circulation pump 4, Successively enter in thinning tank 6 by the first valve 3, first circulation pump 4 and first flowmeter 5.At the same time, organic solvent tank 9 Interior organic solvent passes sequentially through the second valve 10 and second flowmeter 11, is delivered in thinning tank 6.Catalyst mixed component with Organic solvent is uniformly mixed under the agitation of blender 12, and mixed solution is delivered to anti-under the action of second circulation pump 7 later Answer the units such as device 8.
Although being described above in conjunction with function and the course of work of the attached drawing to the utility model, the utility model is simultaneously It is not limited to above-mentioned concrete function and the course of work, the above mentioned embodiment is only schematical, rather than limits Property, those skilled in the art are not departing from the utility model aims and right is wanted under the enlightenment of the utility model It asks under protected ambit, many forms can also be made, these are belonged within the protection of the utility model.
