Abstract
The utility model discloses a building -up reactions washing device that dewaters in succession, including reation kettle, condenser and water knockout drum, the water knockout drum is including wash water knockout drum and second grade water knockout drum in succession, and reation kettle's upper end links to each other with condenser and second grade water knockout drum respectively, and the condenser links to each other with the front end of continuous washing water knockout drum, and the rear end of wasing the water knockout drum in succession links to each other with the second grade water knockout drum. The device simple structure, reasonable in design, the fault rate is low, and the safety in utilization goes with operating stability, the ethanol that produces in the the device desorption reaction in time for the building -up reactions goes on to the forward completely, reduces the side reaction, the shortening reaction time, has improved the synthetic ratio of product.
Description
Technical field
This utility model relates to a kind of wash mill, specifically a kind of synthetic reaction continuous dehydration wash mill.
Background technology
Synthetic reaction refers to that many kinds of substance passes through chemical reaction, to the course of reaction and the reaction equation that produce a kind of chemical product, synthetic reaction is a kind of perfect condition of people, actual production still can produce other products, sulphuric acid guanidinesalt generates ethirimol with N-butyl cyclization, uses toluene to make solvent, and potassium carbonate does acid binding agent, byproduct of reaction is water and ethanol, and one mole of guanidinesalt and two moles of N-butyls generate two moles ethanol and three mole of water.Removing the mixture of second alcohol and water in course of reaction in time, the forward being of value to reaction is carried out.But generally, the liquid that condenser condenses out, only with one-level water knockout drum, can only separate water and a small amount of ethanol, major part water and ethanol because flow process is short and sedimentation does not thoroughly return reactor with toluene.On the one hand, causing reaction not exclusively, be susceptible to side reaction, on the other hand, response speed is slow.
Utility model content
The purpose of this utility model is to provide a kind of synthetic reaction continuous dehydration wash mill, with the problem solving to propose in above-mentioned background technology.
For achieving the above object, the following technical scheme of this utility model offer:
A kind of synthetic reaction continuous dehydration wash mill, including reactor, condenser and water knockout drum, described water knockout drum includes washing water knockout drum and secondary water segregator continuously, the upper end of reactor is connected with condenser and secondary water segregator respectively, condenser is connected with the front end of washing water knockout drum continuously, and the rear end of washing water knockout drum is connected with secondary water segregator continuously.
As further program of the utility model: between condenser and continuously washing water knockout drum, be provided with electromagnetic valve between washing water knockout drum and secondary water segregator and between condenser and secondary water segregator continuously.
As further program of the utility model: washing water knockout drum and secondary water segregator lower end are respectively connected with sewage pipe continuously.
Compared with prior art, the beneficial effects of the utility model are: this apparatus structure is simple, reasonable in design, failure rate is low, safety in utilization and good operation stability；The ethanol that this device can produce in elimination reaction in time so that synthetic reaction is carried out to forward completely, reduces side reaction, shortens the response time, improves the synthetic ratio of product.
Accompanying drawing explanation
Fig. 1 is the structural representation of synthetic reaction continuous dehydration wash mill.
Wherein: 1-reactor, 2-condenser, 3-washs water knockout drum, 4-secondary water segregator, 5-electromagnetic valve continuously.
Detailed description of the invention
Below in conjunction with detailed description of the invention, the technical scheme of this patent is described in more detail.
Refer to Fig. 1, a kind of synthetic reaction continuous dehydration wash mill, including reactor 1, condenser 2 and water knockout drum, described water knockout drum includes washing water knockout drum 3 and secondary water segregator 4 continuously, the upper end of reactor 1 is connected with condenser 2 and secondary water segregator 4 respectively, condenser 2 is connected with the front end of washing water knockout drum 3 continuously, and the rear end of washing water knockout drum 3 is connected with secondary water segregator 4 continuously.Between condenser 2 and continuously washing water knockout drum 3, it is provided with electromagnetic valve 5 between washing water knockout drum 3 and secondary water segregator 4 and between condenser 2 and secondary water segregator 4 continuously.Washing water knockout drum 3 and secondary water segregator 4 lower end are respectively connected with sewage pipe continuously.
nullOperation principle of the present utility model is: by quantitative raw material guanidinesalt、N-butyl、Potassium carbonate and toluene put in reactor 1，Rise high-temperature to react，Toluene after reaction、After mixed gas condensed device 2 condensation of water and ethanol，Initially enter washing water knockout drum 3 continuously，In washing water knockout drum 3 continuously, add a small amount of fresh water (FW) simultaneously，Continuously mixed gas is washed and separates by washing water knockout drum 3，Substantial amounts of water and dissolve ethanol therein by the bottom washing water knockout drum 3 continuously drain into wastewater disposal basin process，Toluene and carry the mixing liquid of a small amount of water secretly and entered by the top washing water knockout drum 3 continuously and continue in secondary water segregator 4 to separate，Toluene after secondary water segregator 4 separates only is carried the water of trace secretly and is returned in reactor 1 and be circulated use，The waste water discharged bottom secondary water segregator 4 also drains into wastewater disposal basin and processes，More than reaction so circulation，Until reaction terminates.This apparatus structure is simple, reasonable in design, failure rate is low, safety in utilization and good operation stability；The ethanol that this device can produce in elimination reaction in time so that synthetic reaction is carried out to forward completely, reduces side reaction, shortens the response time, improves the synthetic ratio of product.
Above the better embodiment of this patent is explained in detail, but this patent is not limited to above-mentioned embodiment, in the ken that one skilled in the relevant art is possessed, it is also possible to various changes can be made on the premise of without departing from this patent objective.
