Abstract
The utility model discloses a metalaxyl production rectifying tower. The metalaxyl production rectifying tower comprises a rectifying tower body, wherein a steam pipeline is connected to the top of the rectifying tower body and is connected with one end of a condenser; the other end of the condenser is connected with a reflux ratio controller through a pipeline; a reflux opening is formed in the upper part of the rectifying tower body and is connected with the reflux ratio controller; the lower end of the reflux ratio controller is connected with a collection pipe; the collection pipe is divided into two paths which are respectively connected with a receiving groove (a) and a receiving groove (b); two sampling ball valves are additionally arranged on the collection pipe at the lower end of the reflux ratio controller; a sampling point is arranged at a position, between the two sampling ball valves, on the collection pipe. The metalaxyl production rectifying tower has the advantages that the sampling point of a rectified object is arranged on the collection pipe instead of the receiving groove, and the two sampling ball valves are additionally arranged; rectification in each pot is performed for 16 hours instead of 24 hours, and the rectification efficiency is improved; the fraction content of a final product is improved from 95 percent to over 98.5 percent, and the content of rectifying fraction ammonia ester is improved; the final content of metalaxyl is improved from 98 percent to 99 percent.
Description
Technical field
The utility model relates to a kind of rectifying column, relates in particular to a kind of metalaxyl and produces rectifying column.
Background technology
Metalaxyl is produced rectifying column, comprise the rectifying tower body, rectifying tower body top is connected with condenser by jet chimney, and condenser is connected with the reflux ratio controller again, under the reflux ratio controller, connects two dump tanks, the sample point of rectifying thing is located on dump tank, every pot of rectifying needs 24 hours, just can obtain the rectifying thing, and rectification efficiency is low, rectifying cut ammonia ester content only has 95%, and the final content of metalaxyl is 98%.Therefore, need to provide a kind of new technical scheme to solve the problems referred to above.
The utility model content
The purpose of this utility model is to provide the metalaxyl that a kind of rectification efficiency is high and produces rectifying column.
The technical solution adopted in the utility model is:
Metalaxyl is produced rectifying column, comprise the rectifying tower body, described rectifying tower body top is connected with jet chimney, described jet chimney is connected with condenser one end, the described condenser other end is connected with the reflux ratio controller by pipeline, described rectifying tower body top has refluxing opening, described refluxing opening is connected with the reflux ratio controller, described reflux ratio controller lower end connects collecting pipe, described collecting pipe divides has two-way to connect respectively dump tank a and dump tank b, on the collecting pipe of described reflux ratio controller lower end, have additional two Sampling ball valves, collecting pipe between two Sampling ball valves is provided with sample point.
The beneficial effects of the utility model: the sample point of rectifying thing is changed to collecting pipe from dump tank, increase by two Sampling ball valves; From 24 hours every pot of rectifying times, become 16 hours, improve rectification efficiency; Final products cut content is increased to more than 98.5% from 95%, has improved the content of rectifying cut ammonia ester; The final content of metalaxyl is increased to 99% from 98%.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Wherein: 1, rectifying tower body, 2, jet chimney, 3, condenser, 4, pipeline, 5, the reflux ratio controller, 6, refluxing opening, 7, collecting pipe, 8, dump tank a, 9, dump tank b, 10, Sampling ball valve, 11, sample point.
The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, metalaxyl of the present utility model is produced rectifying column, comprise rectifying tower body 1, rectifying tower body 1 top is connected with jet chimney 2, jet chimney 2 is connected with condenser 3 one ends, another 3 one ends of condenser are connected with reflux ratio controller 5 by pipeline 4, rectifying tower body 1 top has refluxing opening 6, refluxing opening 6 is connected with reflux ratio controller 5, reflux ratio controller 5 lower ends connect collecting pipe 7, collecting pipe had two-way to connect respectively dump tank a8 and dump tank b9 in 7 minutes, on the collecting pipe 7 of reflux ratio controller 5 lower ends, have additional two Sampling ball valves 10, collecting pipe between two Sampling ball valves 10 is provided with sample point 11.
The sample point of rectifying thing is changed to collecting pipe 7 from dump tank, increase by two Sampling ball valves 10; From 24 hours every pot of rectifying times, become 16 hours, improve rectification efficiency; Final products cut content is increased to more than 98.5% from 95%, has improved the content of rectifying cut ammonia ester; The final content of metalaxyl is increased to 99% from 98%.
