Abstract
The utility model provides a device for detecting the temperature of the bottom of a reaction vessel. The device comprises a temperature measurement galvanic couple, a galvanic couple sheath, an auxiliary pipe and an air emptying pipe. The temperature measurement galvanic couple is arranged on the bottom of the reaction vessel, the galvanic couple sheath is arranged outside the temperature measurement galvanic couple, the auxiliary pipe is fixed on one end, of the temperature measurement galvanic couple, being far from the reaction vessel, the galvanic couple sheath is communicated with the auxiliary pipe, the air emptying pipe is arranged in a pipeline through which the galvanic couple sheath is communicated with the auxiliary pipe, one end of the air emptying pipe is arranged on the top of one end, of the galvanic couple sheath, being close to the reaction vessel, the other end of the air emptying pipe is arranged on the exterior of one end, of the auxiliary pipe, being far from the temperature measurement galvanic couple, and the auxiliary pipe is higher than the galvanic couple sheath. Beneficial effects of the device for detecting the temperature of the bottom of the reaction vessel are that by employing the above technical scheme, the galvanic couple sheath can be completely filled with heat-conducting mediums, and the temperature measurement can be relatively accurate; and the device for detecting the temperature of the bottom of the reaction vessel is advantaged by being simple in structure, convenient to operate, low in cost and the like.
Description
Technical field
The utility model belongs to chemical industry utility appliance field, especially relates to a kind of device of measuring Polycondensation Reactor and Esterification Reactor temperature.
Background technology
When to reactor thermometric, temperature and the actual temperature gap of reactor bottom thermometric galvanic couple feedback are larger, directly cause product quality to decline.Research is found by analysis, and galvanic couple sheath contains air barrier, and because thermometric galvanic couple installation site, reactor bottom is special, heat-conducting medium fails to be full of completely in galvanic couple protecting pipe, causes thermometric to occur very large error.
Summary of the invention
The purpose of this utility model is to provide a kind of device of simple in structure, easy to operate, measurement Polycondensation Reactor and Esterification Reactor temperature that heat-conducting medium can be full of galvanic couple protective sleeve completely, is especially applicable to measuring the temperature of reactor bottom.
The technical solution of the utility model is: a kind of device of measuring Polycondensation Reactor and Esterification Reactor temperature: comprise thermometric galvanic couple, galvanic couple sheath, auxiliary tube, air evacuated tube, described thermometric galvanic couple is located at reactor bottom, its outside is provided with galvanic couple protective sleeve, auxiliary tube is fixed on thermometric galvanic couple one end away from reactor, described galvanic couple protective sleeve is communicated with auxiliary tube, described air evacuated tube is located at the pipeline inside that galvanic couple protective sleeve is communicated with auxiliary tube, its one end is positioned at the top of galvanic couple protective sleeve near one end of reactor, the other end is located at the outside of auxiliary tube away from thermometric galvanic couple one end, and described auxiliary tube is higher than galvanic couple protective sleeve.
Further, described auxiliary tube is welded on galvanic couple protective sleeve.
Further, described air evacuated tube material is plastics.
Advantage and the good effect that the utlity model has are: owing to adopting technique scheme, heat-conducting medium can be full of in galvanic couple protective sleeve completely, and thermometric is more accurate; Have simple in structure, easy to operate, the advantage such as processing cost is low.

Embodiment
As shown in Figure 1, the technical solution of the utility model is: a kind of device of measuring Polycondensation Reactor and Esterification Reactor temperature: comprise thermometric galvanic couple 1, galvanic couple sheath 2, auxiliary tube 3, air evacuated tube 4, described thermometric galvanic couple 1 is located at reactor 5 bottoms, its outside is provided with galvanic couple protective sleeve 2, auxiliary tube 3 is fixed on thermometric galvanic couple 1 one end away from reactor 5, described galvanic couple protective sleeve 2 is communicated with auxiliary tube 3, heat-conducting medium injects among connecting pipeline by auxiliary tube 3, described air evacuated tube 4 is located at the pipeline inside that galvanic couple protective sleeve 2 is communicated with auxiliary tube 3, its one end is positioned at the top of galvanic couple protective sleeve 2 near one end of reactor 5, the other end is located at the outside of auxiliary tube 3 away from thermometric galvanic couple 1 one end, for the air of pipeline is drained, and described auxiliary tube 3 is higher than galvanic couple protective sleeve 2, utilize law of connected vessels, air in pipeline is passed through outside air evacuated tube 4 discharge lines, after air is all discharged, auxiliary tube 3 liquid levels are higher than liquid level in galvanic couple protective sleeve 2, guarantee the accuracy of thermometric galvanic couple 1 thermometric.
In the present embodiment, described auxiliary tube 3 is welded on galvanic couple protective sleeve 2, and described air evacuated tube 4 materials are plastics.
The course of work of this example: heat-conducting medium is injected to auxiliary tube; by air evacuated tube, the air in pipeline is drained, heat-conducting medium is full of in galvanic couple protective sleeve completely, removes disturbing factor; strengthen thermometric degree of accuracy, thermometric galvanic couple is inserted to reactor bottom and carry out thermometric.
Above an embodiment of the present utility model is had been described in detail, but described content is only preferred embodiment of the present utility model, can not be considered to for limiting practical range of the present utility model.All equalization variation and improvement etc. of doing according to the utility model application range, within all should still belonging to patent covering scope of the present utility model.
