Description
Technical Field
The utility model belongs to the technical field of chemical production, especially, relate to a chemical production is convenient for device of distillate sample.
Background
In the process of implementing the present invention, the inventor finds that the prior art has at least the following problems:
at present, in chemical production, particularly, polybasic acid and polyhydric alcohol are subjected to esterification reaction at high temperature and high pressure, distillate generated by the reaction needs to be sampled and measured at different stages of the reaction to determine the physical and chemical indexes, judge the size, the composition of components and the like, and a traditional reaction device cannot accurately sample and measure in time, so that a simple device is needed to take the distillate.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that a can in time prepare to take out the distillate is provided, the testing personnel of being convenient for accurately judge its composition, the chemical production of survey physics and chemistry index is convenient for the device of distillate sample.
In order to solve the technical problem, the utility model discloses the technical scheme who adopts is: an apparatus for facilitating the sampling of distillate in chemical production, comprising:
a distillate line;
a sample liquid pipeline, the first end of which is connected with the distillate liquid pipeline;
the ball valve is arranged on the sampling liquid pipeline;
the waste water tank is communicated with the tail end of the distillate pipeline;
the pneumatic regulating valve is arranged at the connecting end of the sampling liquid pipeline and the distillate pipeline;
and the detection instrument can detect the liquid in the waste water tank.
The ball valve comprises a first ball valve and a second ball valve, and the first ball valve and the second ball valve are sequentially arranged on the sampling liquid pipeline.
And a valve is arranged at the tail end of the distillate pipeline.
One of the technical schemes has the advantages or beneficial effects that the distillate can be prepared and taken out in time, so that detection personnel can conveniently and accurately judge the composition of the components, determine physical and chemical indexes, further adjust the alcohol cooling size, and finally achieve the effects of convenience, safety, energy conservation and environmental protection.
Drawings
FIG. 1 is a schematic structural diagram of an apparatus for facilitating distillate sampling in chemical production provided in an embodiment of the present invention;
the labels in the above figures are: 1. the device comprises a first ball valve, a second ball valve, a sampling container, a detection instrument, a pneumatic regulating valve, a waste water tank, a distillate pipeline and a pneumatic regulating valve, wherein the first ball valve 2, the second ball valve 3, the sampling container 4, the detection instrument 5, the pneumatic regulating valve 6 and the waste water tank 7 are arranged in the device.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.
Referring to fig. 1, an apparatus for facilitating distillate sampling for chemical production, comprises:
a distillate line;
a sample liquid pipeline, the first end of which is connected with the distillate pipeline;
the ball valve is arranged on the sampling liquid pipeline;
the waste water tank is communicated with the tail end of the distillate pipeline;
the pneumatic regulating valve is arranged at the connecting end of the sampling liquid pipeline and the distillate pipeline;
and the detection instrument can detect the liquid in the waste water tank.
The ball valve includes first ball valve and second ball valve, and first ball valve and second ball valve set gradually on the sample liquid pipeline. The end of the distillate pipeline is provided with a valve.
The device is arranged on the pipeline between all the condenser water outlet pipelines of the first-stage reaction kettle and the waste water collecting tank. The device consists of two ball valves, a sampling container, a flange and an electrical element (pneumatic regulating valve), and by operating the two ball valves and the electrical element, the distillate generated by the reaction is sampled at regular time, physical and chemical indexes are measured, and the opening degree of alcohol cooling is further regulated, so that the device has the functions of being more visual, simple, safe and environment-friendly compared with the prior art.
In traditional reaction sampling process, because reation kettle exists the pressure, so need pay attention to safety, avoid scalding, firstly, start pneumatic control valve when preparing the sample, wait for 10 seconds after, open first ball valve, open a less angle, open the second ball valve again, distillate flows into the sampling container the inside directly, wherein place a beaker or erlenmeyer flask, wait that the sample gets the back, in time utilize detecting instrument to survey the physicochemical index of sample, if qualified, can directly arrange to waste water collection tank through the flange, if the physicochemical index is unqualified, can carry out sampling work on next step through pneumatic control valve, remind interior central control personnel in time to adjust the cold size of mellow wine simultaneously, finally make the physicochemical index of distillate reach qualified requirement.
After the structure is adopted, the distillate can be prepared and taken out in time, so that detection personnel can conveniently and accurately judge the component composition of the distillate, determine the physical and chemical indexes, further adjust the alcohol cooling size, and finally achieve the effects of convenience, safety, energy conservation and environmental protection.
The present invention has been described above with reference to the accompanying drawings, and it is obvious that the present invention is not limited by the above-mentioned manner, and various insubstantial improvements can be made without modification to the method and technical solution of the present invention, or the present invention can be directly applied to other occasions without modification, all within the scope of the present invention.
