Abstract
The utility model discloses a liquid recovery system, comprising a liquid accumulation tank, a liquidometer with display arranged at one side of the liquid accumulation tank, and a PLC (Programmable Logic Controller) control system, wherein a low-liquid level alarm point, a high-liquid level alarm point and a highest-liquid level alarm point are formed on the liquidometer; the low-liquid level alarm point, the high-liquid level alarm point and the highest-liquid level alarm point are electrically connected with the PLC control system, respectively; the PLC control system is connected with a first recovery pump and a second recovery pump, respectively; the bottom of the liquid accumulation tank are communicated with a recovery pipe network through the first recovery pump and the second recovery pump, respectively. The liquid recovery system is capable of reliably and effectively monitoring the state of the liquid level in the liquid accumulation tank and the working states of the recovery pump while recovering residual liquid after liquid analysis; with the design of the high-liquid level alarm point and the highest-liquid level alarm point in the liquidometer and the coordination arrangement of two groups of recovery pumps, overflow of the liquid from the liquid accumulation tank caused by damage of the liquidometer and the recovery pumps is effectively prevented.
Description
Technical field
The utility model relates to a kind of device that reclaims after chemical engineering industry adopts online fluid analyte meter to poisonous and harmful or flammable and combustible liquids analysis.
Background technology
At present, in chemical industry, the raffinate after the continuous analysis meter analysis of on-line liquid is trench emission treatment on the spot substantially, if contain poisonous, harmful or inflammable, explosive liquid in the raffinate, according to the danger of chemical industry occasion, be not allow directly discharging.Existing liquid recovery system, often undesirable because the regenerative apparatus function is done, cause the waste liquid in the liquid hydrops jar to overflow, and cause the scene unsafe condition to occur.
The utility model content
Goal of the invention of the present utility model is: at the problem of above-mentioned existence, providing a kind of can carry out reliable recovery to poisonous, harmful and inflammable, explosive liquid, simultaneously the liquid recovery system that can diagnose and report to the police the system failure.
The technical solution of the utility model is achieved in that a kind of liquid recovery system, comprise the hydrops jar, be arranged on liquidometer and the PLC control system of the band demonstration of hydrops jar one side, it is characterized in that: be respectively arranged with low liquid level warning point at described liquidometer, high liquid level warning point and high liquid level warning point, described low liquid level warning point, high liquid level warning point and high liquid level warning point are electrically connected with the PLC control system respectively, described PLC control system is respectively with first, second reclaims pump connects, and described hydrops pot bottom is respectively by first, second reclaims pump is communicated with the recovery pipe network.
Liquid recovery system described in the utility model, it reclaims the pipeline that pump inlet is communicated with at described hydrops pot bottom and first, second and is respectively arranged with shutoff valve, is disposed with check valve and shutoff valve respectively on described first, second reclaims pump discharge and pipeline that the recovery pipe network is communicated with.
Liquid recovery system described in the utility model, it is provided with flame trap above described hydrops jar, be provided with manual tapping valve in described hydrops jar bottom.
The utility model can be after to fluid analysis in the raffinate recovery, reliably the state of liquid level in the hydrops jar and the mode of operation of recovery pump are carried out the actv. monitoring, design by high liquid level warning point in the liquidometer and high liquid level warning point and two groups reclaim being equipped with of pumps, thereby effectively prevent because liquidometer and reclaim the damage of pump and cause liquid to overflow from the hydrops jar.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Mark among the figure: 1 is the hydrops jar, and 2 is liquidometer, and 2a is low liquid level warning point, 2b is the high liquid level warning point, 2c is high liquid level warning point, and 3 is the PLC control system, and 4a first reclaims pump, 4b is the second recovery pump, 5 for reclaiming pipe network, and 6 is shutoff valve, and 7 is check valve, 8 is flame trap, and 9 is manual tapping valve.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is done detailed explanation.
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
As shown in Figure 1, a kind of liquid recovery system comprises hydrops jar 1, is arranged on liquidometer 2 and PLC control system 3 that the band of hydrops jar 1 one sides shows, all can show the liquid level that the hydrops jar is interior on the on-the-spot and control cabin; Be respectively arranged with low liquid level warning point 2a, high liquid level warning point 2b and high liquid level warning point 2c at described liquidometer 2, described low liquid level warning point 2a, high liquid level warning point 2b and high liquid level warning point 2c are electrically connected with PLC control system 3 respectively, described PLC control system 3 reclaims pump 4a with first respectively and the second recovery pump 4b is connected, and described hydrops jar 1 bottom is reclaimed pump by first, second respectively and is communicated with recovery pipe network 5.
Wherein, be respectively arranged with shutoff valve 6 in described hydrops jar 1 bottom with the pipeline that first, second recovery pump inlet is communicated with, be disposed with check valve 7 and shutoff valve 6 respectively on described first, second reclaims pump discharge and reclaim the pipeline that pipe network 5 is communicated with, the arranging of check valve can prevent from causing hydrops jar liquid flooding because recovery pipe network fluctuation of pressure causes the waste liquid hydrops jar of playing a reversed role back.Be provided with flame trap 8 above described hydrops jar 1, the tank body internal pressure is carried out balance, guarantee that waste liquid normally enters in the hydrops jar, flame trap prevents safety misadventure simultaneously; Be provided with manual tapping valve 9 in described hydrops jar 1 bottom, dirty lime set in the hydrops jar is carried out regular manual drain.
Principle of work of the present utility model: as shown in Figure 1, waste liquid at first enters the hydrops jar through pipeline, when liquid level reaches high liquid level warning point in the hydrops jar, alerting signal is transferred to the PLC control system, export a high liquid level pre-alarm simultaneously to control cabin, the PLC control system is controlled first, second and is reclaimed any one startup in the pump, makes the hydrops jar reclaim pump by the first recovery pump or second and is communicated with the recovery pipe network.
If the recovery failure of pump that elder generation starts, liquid level also can increase in the hydrops jar so, when liquid level reaches high liquid level warning point, output alarm signal is to the PLC control system, export a fault alarm simultaneously to control cabin, inform present system running state, the PLC control system is controlled first, second recovery pump and is started simultaneously, make the hydrops jar reclaim pump by first, second and be communicated with the recovery pipe network, thereby effectively avoid the hydrops jar overflow phenomena that causes because of single recovery failure of pump.
When liquid level in the hydrops jar reached low liquid level warning point, the recovery pump that moves by the control of PLC control system stopped.
The above only is preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of within spirit of the present utility model and principle, doing, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
