Abstract
The utility model, which belongs to the industrial control field, relates to a control apparatus capable of preventing water carrying of a molecular sieve, so that a problem that running of an air separation unit is greatly influenced due to the water carrying of the molecular sieve in the existing industrial control system can be solved. A waste water draining outlet is arranged at a bottom of an air cooling tower, wherein the waste water draining outlet is communicated with an inlet of a drain valve by a pipeline; and the outlet of the drain valve is connected with an inlet of a waste water drain pipeline. A flowmeter us arranged at the lower half of the outer side wall of the air cooling tower; the measurement data output terminal of the flowmeter is connected with a starting and stopping control terminal of an automatic drain valve of the molecular sieve. A steam drain outlet is arranged at the top end of the air cooling tower and is communicated with an inlet of the molecular sieve by a pipeline; and an outlet of the molecular sieve is communicated with an inlet of a manual maintenance valve by a pipeline; an outlet of the manual maintenance valve is communicated with an inlet of the drain valve and an inlet of the automatic drain valve of the molecular sieve by pipelines; and an outlet of the automatic drain valve of the molecular sieve is connected with the inlet of the waste water drain pipeline.
Description
Technical field
The utility model relates to and prevents molecular sieve band water controller, belongs to industrial control field.
Background technology
The structure of molecular sieve is the cancellated natural or artificial synthetic chemical substance of tool.Such as cross-link dextran, zeolite etc., when as chromatography media, can carry out classification to potpourri by molecular size separates, the material requirement of participating in reaction in air cooling tower is pure, therefore, adopt molecular sieve to consider the removal of impurity, but the normal operation of molecular sieve band water meeting considerable influence air separation unit, serious even needs are changed molecular sieve, can cause huge economic loss.
Summary of the invention
The utility model purpose is in order to solve the problem of molecular sieve band water meeting considerable influence air separation unit operation in the existing industrial control system, a kind of molecular sieve band water controller that prevents to be provided.
The molecular sieve band water controller that prevents described in the utility model, it comprises air cooling tower, flowmeter, molecular sieve and draining valve, it also comprises manual maintenance valve and molecular sieve automatic drain valve,
Bottom at air cooling tower arranges waste water discharge opening, and described waste water discharge opening is connected by pipeline with the entrance of draining valve, and the outlet of draining valve connects the entrance of discharge of wastewater pipeline;
Lateral wall the latter half at air cooling tower arranges two flow measurement ports, and described two flow measurement ports are connected respectively with two measurement port of flowmeter;
The measurement data output terminal of flowmeter links to each other with the on off control end of molecular sieve automatic drain valve;
The top of air cooling tower is provided with steam outlet, be connected by pipeline between the entrance of described steam outlet and molecular sieve, the molecular sieve outlet is connected by pipeline with the entrance of manual maintenance valve, and manually the outlet of maintenance valve is connected by pipeline with the entrance of draining valve and the entrance of molecular sieve automatic drain valve simultaneously;
The outlet of molecular sieve automatic drain valve connects the entrance of discharge of wastewater pipeline.
Advantage of the present utility model: the utility model device project organization is simple, control is convenient, by a pipeline that connects the bottom discharge pipe is installed at the air cooling tower outlet conduit, the automatic drain valve of liquid level control is installed on the pipeline, utilize fluid carry-over principle and water seal from drainage principle, the water that air is carried in realization secretly separates under Action of Gravity Field, by water-seal principle unnecessary water is discharged tower and has prevented to greatest extent molecular sieve band water outward, so that commercial production is carried out smoothly.
Description of drawings
Fig. 1 is the structural representation that prevents molecular sieve band water controller described in the utility model.
Embodiment
Embodiment one: below in conjunction with Fig. 1 present embodiment is described, the described molecular sieve band water controller that prevents of present embodiment, it comprises air cooling tower 1, flowmeter 2, molecular sieve 3 and draining valve 5, it also comprises manual maintenance valve 6 and molecular sieve automatic drain valve 7,
Bottom at air cooling tower 1 arranges waste water discharge opening, and described waste water discharge opening is connected by pipeline with the entrance of draining valve 5, and the outlet of draining valve 5 connects the entrance of discharge of wastewater pipeline;
Lateral wall the latter half at air cooling tower 1 arranges two flow measurement ports, and described two flow measurement ports are connected respectively with two measurement port of flowmeter 2;
The measurement data output terminal of flowmeter 2 links to each other with the on off control end of molecular sieve automatic drain valve 7;
The top of air cooling tower 1 is provided with steam outlet, be connected by pipeline between the entrance of described steam outlet and molecular sieve 3, molecular sieve 3 outlets are connected by pipeline with the entrance of manual maintenance valve 6, and manually the outlet of maintenance valve 6 is connected by pipeline with the entrance of draining valve 5 and the entrance of molecular sieve automatic drain valve 7 simultaneously;
The outlet of molecular sieve automatic drain valve 7 connects the entrance of discharge of wastewater pipeline.
By a pipeline that connects the bottom discharge pipe is installed at air cooling tower 1 outlet conduit, the automatic drain valve 7 of liquid level control is installed on the pipeline, utilize fluid carry-over principle and water seal from drainage principle in the design, the water that air is carried in realization secretly separates under Action of Gravity Field, by water-seal principle unnecessary water is discharged outside the tower.
System closes manual maintenance valve 6 before starting, and prevents that the water of having altered from entering in the molecular sieve 3, after system starts, opens manual maintenance valve 6, manually closes manual maintenance valve 6 first when device needs repairing, and keeps in repair again.
When the water level in flowmeter 2 detects air cooling tower 1 was higher than the emptying threshold value of setting, excessive moisture was discharged in control signal control molecular sieve automatic drain valve 7 operations of flowmeter 2 outputs; When the water level in flowmeter 2 detects air cooling tower 1 was lower than the emptying threshold value of setting, the control signal control molecular sieve automatic drain valve 7 of flowmeter 2 outputs was out of service.The emptying threshold value of described setting is different and different according to the specification of air cooling tower 1, is taken the circumstances into consideration to set according to actual conditions by the technician.
Embodiment two: present embodiment is described further embodiment one, and it also comprises gas admittance valve 4, in the first half of the sidewall of air cooling tower 1 air intake opening is set, and is connected by admission line between described air intake opening and the gas admittance valve 4.
