Description
Technical Field
The utility model relates to a liquid phosphite production technical field especially relates to a nitrogen device is led to phosphorous acid diisooctyl benzene that can stabilize flow.
Background
The nitrogen is required to be introduced to purge the residual byproduct phenol in the later stage of the production of the diisooctyl phenyl phosphite, but the flow of the nitrogen is difficult to control. If the flow is too low and the phenol purging is not thorough enough, products with over-standard phenol content need to be reworked; if the flow is too high, the waste of nitrogen is caused. Both of the above cases result in an increase in production cost.
SUMMERY OF THE UTILITY MODEL
The main objective of the utility model is to provide a but the nitrogen device that leads to of the diisooctyl phenyl phosphite of steady flow, adjustable nitrogen flow makes its stable output, neither can produce the waste of nitrogen gas nor can lead to sweeping phenol thoroughly inadequately.
The purpose of the utility model can be achieved by adopting the following technical scheme:
a flow-stable nitrogen introducing device for diisooctyl phenyl phosphite comprises a gas transmission pipeline, wherein one end of the gas transmission pipeline is connected with a nitrogen charging device, and the other end of the gas transmission pipeline is connected with a reaction kettle;
the gas transmission pipeline is sequentially provided with a first valve and a second valve along the length direction, and a flow meter is arranged on the pipeline of the gas transmission pipeline between the first valve and the second valve.
Preferably, the gas pipeline system further comprises a branch pipeline penetrating through the gas pipeline, the branch pipeline is arranged between the first valve and the second valve, and the flow meter is arranged on the branch pipeline.
Preferably, the flow meter is a rotameter.
Preferably, the branch pipeline is further provided with a third valve, and the third valve and the flow meter are distributed along the length direction of the branch pipeline.
The utility model has the advantages of:
the first valve and the second valve provided by the utility model are matched for use, nitrogen with a preset quantity can be injected into the gas transmission pipeline, and meanwhile, the first valve is conveniently controlled by the flowmeter so as to adjust the nitrogen flow entering the gas transmission pipeline between the first valve and the second valve and conveniently inject a set flow value of the nitrogen into the reaction kettle; the third valve, the branch pipeline and the flowmeter are matched for use, so that the air outlet of the rotameter is conveniently emptied, and the nitrogen amount of a set value is favorably charged into the gas transmission pipeline.
