Abstract
The utility model relates to a liquid level detection device for a gas-liquid separating tank of a chlorine gas compressor, the liquid level detection device comprises a DCS system, a data cable, a gas-liquid separating tank, a dry reed tube liquid level gauge and a magnetic float. The dry reed tube liquid level gauge is arranged at one end of the top part of the gas-liquid separating tank, an inductor of the dry reed tube liquid level gauge is extended into the gas-liquid separating tank, the magnetic float is further sleeved on the inductor of the dry reed tube liquid level gauge; and the signal output of the dry reed tube liquid level gauge is electrically connected with the DCS system by the data cable. Compared with the prior art, the liquid level detection device has the advantages of accurate detection of liquid level and no generation of false signals; and when used in a petroleum refining system, the liquid level detection device detects the liquid level of the gas-liquid separating tank of the chlorine gas compressor, thereby ensuring accurate data and avoiding the occurrence of compressor interlock shutdown phenomenon caused by detection data errors.
Description
Technical field
The utility model relates to chemical industry for making chlorine and alkali chlor-alkali level gauging technical field, is specifically related to a kind of liquid level detection device that is used for the chlorine gas compressor knockout drum.
Background technology
At present, the Level Detection of chlorine gas compressor knockout drum all adopts the level switch mode that liquid level is put to detect in the chlor-alkali workshop of chemical industry for making chlorine and alkali system, and " low low newspaper, low newspaper, high newspaper, high newspaper " signal is sent to DCS system linkage control compressor, but, false positive signal often appears in level switch in testing process, cause DCS system error in judgement and cause the compressor interlocking to stop, can draw whole workshop when serious and stop.
The utility model content
The purpose of this utility model is exactly the defective that exists at prior art, and a kind of liquid level detection device that is used for the chlorine gas compressor knockout drum that liquid level is reacted accurately and don't taken place wrong report is provided.
Its technical scheme is: comprise DCS system, data cable, knockout drum, tongue tube liquid level gauge and magnetic float, the tongue tube liquid level gauge is installed in an end of gas-liquid separation tank top, the inductor of tongue tube liquid level gauge stretches to knockout drum inside, also is with magnetic float on the inductor of tongue tube liquid level gauge; The signal output of tongue tube liquid level gauge is electrically connected the DCS system through data cable.
Described tongue tube liquid level gauge and knockout drum are threaded engagement.
The utility model has the advantage that Level Detection accurately and not produces glitch compared with prior art, in the chlor-alkali system, use, liquid level to the chlorine gas compressor knockout drum detects, can guarantee that data are accurate, stop because of detecting the generation that the data error causes compressor interlocking parking phenomenon.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Embodiment
Elaborate by embodiment below in conjunction with Figure of description:
As shown in drawings, comprise DCS system 5, data cable 4, knockout drum 1, tongue tube liquid level gauge 2 and magnetic float 3, tongue tube liquid level gauge 2 is installed in an end at knockout drum 1 top, the inductor of tongue tube liquid level gauge 2 stretches to knockout drum 1 inside, also is with magnetic float 3 on the inductor of tongue tube liquid level gauge 2; The signal output of tongue tube liquid level gauge 2 is electrically connected DCS system 5 through data cable 4.
When using the utility model, be inserted in magnetic float 3 on the inductor with tongue tube liquid level gauge 2 after, again tongue tube liquid level gauge 2 threaded engagement are installed in the end at knockout drum 1 top; With being set in the DCS configuration, " low, low, high, high " report to the police.When knockout drum 1 has liquid to enter, magnetic float 3 will knockout drum inside liquid position and move up and down, thereby make the corresponding electric signal of tongue tube liquid level gauge 2 outputs, this electric signal is transferred to DCS system 5 through data cable 4, DCS system 5 will compare according to the electric signal of configuration setting and 2 outputs of tongue tube liquid level gauge, show then or report to the police, this working method can guarantee that data are accurate, stops because of detecting the generation that the data error causes compressor interlocking parking phenomenon.
Claims (2)
1, a kind of liquid level detection device that is used for the chlorine gas compressor knockout drum, comprise DCS system, data cable, knockout drum, tongue tube liquid level gauge and magnetic float, it is characterized in that: the tongue tube liquid level gauge is installed in an end of gas-liquid separation tank top, the inductor of tongue tube liquid level gauge stretches to knockout drum inside, also is with magnetic float on the inductor of tongue tube liquid level gauge; The signal output of tongue tube liquid level gauge is electrically connected the DCS system through data cable.
