Below in conjunction with accompanying drawing, a kind of cooling device about the reaction of synthesis gas dimethyl oxalate of the present utility model is described further.
Accompanying drawing explanation
Fig. 1 is a kind of front view of the cooling device about the reaction of synthesis gas dimethyl oxalate.
Detailed description of the invention
As shown in Figure 1, a kind of cooling device about the reaction of synthesis gas dimethyl oxalate of the utility model comprises the cooling tube 11 on drum 2, first pump 31, second pump 32, first valve 41, second valve 42 and oxonation device 1.Cooling tube 11 top is connected with drum 2 by pipeline.Steam is discharged from upper pipeline by drum 2, and drum 2 makes up the evaporation of liquid by middle pipe liquid make-up, and drum 2 is discharged after liquid cools by lower pipe, and lower pipe is parallel with the first pump 31 and the second pump 32.First pump 31 and the second pump 32 are to infusion fluid bottom cooling tube 11, and the input/output port place of the first pump 31 and the second pump 32 is respectively equipped with the first valve 41 and the 3rd valve 43, and the utility model also comprises the second valve 42, short circuit pipeline and cylinder 5.
Pipeline is flexible duct, and pipeline material is ocean composite.Cylinder 5 is also connected with bottom drum 2.
The input port of the first valve 41 is communicated with the delivery outlet of the 3rd valve 43 by short circuit pipeline.The second valve 42 is provided with in short circuit pipeline.
Cylinder 5, first pump 31, second pump 32 and oxonation device 1 are fixed by support column and rotating disk 6.Fix with the output shaft of motor 61 bottom rotating disk 6.Motor 61 to be rotation amplitudes the be reciprocally swinging motor of 10 °.
During normal use, the first valve 41 and the 3rd valve 43 are opened, the second valve 42 is closed, and the first pump 31, second pump 32 normally works.When the first pump 31 and the second pump 32 break down, first valve 41 and the 3rd valve 43 are closed, second valve 42 is opened, first pump 31, second pump 32 short circuit is fallen by short circuit pipeline, cylinder 5 vibrates drum 2 and drum 2 and cooling tube 11 rock by rotating disk, thus promotion heat exchange, avoid because cooling interrupts and have an accident.
Above-described embodiment is only be described preferred embodiment of the present utility model; not scope of the present utility model is limited; under the prerequisite not departing from the utility model design spirit; the various distortion that those of ordinary skill in the art make the technical solution of the utility model and improvement, all should fall in protection domain that the utility model claims determine.
