Abstract
The utility model discloses a reation kettle negative micro -pressure controlling means, include: reation kettle, U type pipe, salt solution, resistance stick, negative micro -pressure controller, air exhauster, frequency -variable controller, at the air exhauster during operation, can produce certain negative pressure to reation kettle, this negative pressure will result in U type pipe mesohaline water position to change, form certain difference in height, and the length that the resistance stick ingresses the salt aquatic changes thereupon, and the resistance value that the controller records also can change, and if the resistance value strengthens with the setting value deviation, the converter of air exhauster will be controlled to the controller so, adjusts the rotational speed of air exhauster, changes the negative pressure among the reation kettle, makes the negative pressure value maintain near setting value all the time.
Description
Technical field
The utility model relates to a kind of reactor tiny structure control device, belongs to automation control area.
Background technology
In the routine work of reactor; frequent meeting is with the generation of a little toxic and harmful; air exhauster is needed to be extracted out; but directly use air exhauster exhausting; may have suction draught spends little; toxic and harmful is not taken out not go out, and dynamics is excessive may extract out the material in reactor, also wastes energy.
Summary of the invention
The purpose of this utility model is to provide a kind of reactor tiny structure control device, the frequency-variable controller of air exhauster is controlled by the resistance of measuring resistance rod, thus control the working speed of air exhauster, negative pressure in adjustment reactor, makes the air pressure in reactor be in a certain tiny structure state of value all the time.
The technical solution of the utility model is:
A kind of reactor tiny structure control device, comprising: reactor, U-tube, salt solution, resistor rod, tiny structure controller, air exhauster, frequency-variable controller; Reactor one interface is connected to one side of U-tube, salt solution is filled with in U-tube, U-tube another side inserts a resistor rod, resistor rod lower end is inserted in salt solution, resistor rod upper end is connected to tiny structure controller, another interface of reactor is connected to air exhauster, and air exhauster is connected with frequency-variable controller, and frequency-variable controller is also connected with tiny structure controller.
Operation principle of the present utility model: a kind of reactor tiny structure control device, when air exhauster works, certain negative pressure can be produced to reactor, this negative pressure will cause salt solution position in U-tube to change, formation certain altitude is poor, the length that resistor rod is immersed in salt solution changes thereupon, the resistance value that controller is surveyed also changes, if resistance value and setting value deviation strengthen, so controller will control the frequency converter of air exhauster, the rotating speed of adjustment air exhauster, changes the negative pressure in reactor, negative pressure value is maintained near setting value all the time.
The utility model has the advantages that: the resistance value being detected resistor rod by a controller, by the difference of this resistance value and setting value, regulate the frequency conversion of air exhauster, and then controller exhausting dynamics, change the position of salt solution and the length of resistor rod immersion salt solution, thus change resistance value, be the process of a loop control.This device is a simple and practical environmental protecting device, and operating cost is low.
