Abstract
The utility model relates to a liquid level control system of a first drainage receiver used for material receiving of the first drainage receiver. The system is characterized by comprising a first drainage receiver (1), a heat medium feeding pot (2) and a second drainage receiver (3). The material outlet of the first drainage receiver (1) is connected with a material outlet pipe (4). The end of the material outlet pipe (4) is in parallel connection with a material receiving pipe (5), a heat medium feeding pot material feeding pipe (6) and a second drainage receiver material feeding pipe (7). The material receiving pipe (5) is provided with a material receiving valve (5.1). The heat medium feeding pot material feeding pipe (6) is provided with a flow transmitter (6.1). A control circuit (8) is disposed between the flow transmitter (6.1) and the material receiving valve (5.1). The control circuit (8) is provided with a liquid level controller (8.1). The system is advantaged by being high in liquid level control precision and saving manpower.
Description
Technical field
The utility model relates to a kind of the first drainer, relates in particular to a kind of the first drainer tank level control system for the first drainer feed back, belongs to the chemical plant field.
Background technology
In producing PET Process, need to carry out condensation to material with the first drainer, the more difficult control of liquid level in the first traditional drainer, need to regulate the first drainer feed back speed manually.For the maximization production line, if need workman's manual operation, waste a large amount of artificial, and the more difficult assurance of the first drainer liquid level control accuracy.Therefore seek a kind of liquid level control accuracy higher, save artificial the first drainer tank level control system for the first drainer feed back particularly important.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of liquid level control accuracy higher, saves artificial the first drainer tank level control system for the first drainer feed back.
The purpose of this utility model is achieved in that
A kind of the first drainer tank level control system for the first drainer feed back, it comprises the first drainer, heating agent feeding tank and the second drainer, the discharging opening of described the first drainer connects a discharge pipe, the end of described discharge pipe is connected in parallel to the feed back pipeline, heating agent feeding tank feeding pipeline and the second drainer feeding pipeline, the end of described feed back pipeline is connected with the feedback outlet of the first drainer, the end of described heating agent feeding tank feeding pipeline is connected with the charging aperture of heating agent feeding tank, the end of described the second drainer feeding pipeline is connected with the charging aperture of the second drainer, two discharge pumps have been arranged in parallel on described discharge pipe, be provided with the feed back valve on described feed back pipeline, be provided with flow transmitter on described heating agent feeding tank feeding pipeline, be provided with operation circuit between described flow transmitter and feed back valve, be provided with fluid level controller on described operation circuit.
Compared with prior art, the beneficial effects of the utility model are:
The utility model passes through the aperture of the signal controlling material returning valve of operation circuit, thereby controls the first drainer self feed back speed, guarantees that the first drainer liquid level is able to accurate control.Should there is the liquid level control accuracy for the first drainer tank level control system of the first drainer feed back higher, save artificial advantage.
