Description
Technical Field
The utility model relates to a soil thermal desorption technical field, concretely relates to soil thermal desorption is with storage jar liquid level automatic discharging equipment.
Background
At present, in the soil remediation industry, liquid discharge equipment in a storage tank of a thermal desorption system mainly depends on manual operation. In actual operation, personnel must be kept uninterrupted, the proportion of occupied labor force is large, meanwhile, whether the system can stably operate or not has large influence on a subsequent processing system, and when the system is large and the process flow is complex, the responsibility of operators on duty and the operation safety and quality of skilled programs of the system are determined. Therefore, the stability of the whole system is ensured, unnecessary machine halt and maintenance are reduced, and process interruption is avoided, so that the construction period, the idle personnel and equipment and the economic loss are reduced, and great practical requirements are met in the soil thermal desorption industry.
SUMMERY OF THE UTILITY MODEL
Not enough to prior art, the utility model provides a soil thermal desorption is with storage jar liquid level automatic discharge device, the state of liquid level in the effectual monitoring storage jar according to high liquid level automatic start delivery pump, low liquid level automatic stop delivery pump to guarantee the continuous safe, the effectual operation of economy of soil restoration operation.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
an automatic liquid level discharge device of a storage tank for soil thermal desorption comprises a storage tank for soil thermal desorption, a liquid level sensor for detecting the liquid level in the storage tank for soil thermal desorption, a logic controller, a contactor and a liquid discharge pump; the liquid level sensor is electrically connected with the logic controller, the logic controller is electrically connected with the contactor, the contactor is connected with the liquid discharge pump, and a liquid inlet of the liquid discharge pump is connected with a liquid discharge port of the storage tank.
Furthermore, the high liquid level set point and the low liquid level set point of the storage tank for soil thermal desorption are respectively externally connected with the liquid level sensor through an upper pipeline and a lower pipeline, and isolation valves are respectively arranged on the upper pipeline and the lower pipeline.
Has the advantages that:
1. the actual state of the liquid level can be monitored in real time in the operation process, so that the operation condition of the discharge equipment can be known.
2. The automation degree of system control can be effectively increased, the labor cost is saved, and the income is increased.
3. The liquid discharge pump can be opened and closed accurately in time, and the reliability and stability of system operation are improved.

Fig. 1 is a schematic structural diagram of the present invention.
Numbering in the figures: 1. a storage tank drain outlet; 2. a liquid inlet valve; 3. a peephole; 4. an upper isolation valve; 5. isolating the lower isolation valve; 6. a pump inlet valve; 7. a liquid discharge pump; 8. a contactor; 9. a check valve; 10. a liquid level sensor; 11. A storage tank for thermal desorption of soil; 12. a logic controller.
Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
As shown in figure 1, the utility model comprises a storage tank 11, wherein the storage tank 11 is provided with a liquid inlet and a sewage draining outlet 1, and a liquid inlet pipeline is provided with a liquid inlet valve 2. The high liquid level set point and the low liquid level set point of the storage tank 11 are respectively connected with a liquid level sensor 10 through an upper pipeline and a lower pipeline, and an upper isolation valve 4 and a lower isolation valve 5 are respectively arranged on the upper pipeline and the lower pipeline. The liquid level sensor 10 is electrically connected with the logic controller 12, the logic controller 12 is electrically connected with the contactor 8, and the contactor 8 is connected with the liquid discharge pump 7. The liquid inlet of the liquid discharge pump 7 is connected with the liquid discharge port of the storage tank 11, and the connecting pipeline is provided with a pump inlet valve 6.
The utility model discloses a concrete implementation method: liquid in the storage tank 11 enters through the liquid inlet and is remotely transmitted to the logic controller 12 through the liquid level sensor 10 after reaching a set high liquid level, the logic controller 12 triggers the contactor 8 to be closed through a control loop, and the pump inlet valve 6 and the check valve 9 of the liquid discharge pump 7 are kept in a normally opened state, so that the liquid discharge pump 7 operates and discharges the liquid in the storage tank 11; after the liquid discharge pump 7 works, the liquid level in the storage tank 11 continuously drops, after a set low liquid level set point is reached, the liquid level sensor 10 remotely transmits the liquid level to the logic controller 12, the logic controller 12 triggers the contactor 8 to be disconnected through a control loop, and the liquid discharge pump 7 stops running, so that the liquid level state is monitored in real time, and the automatic start-stop discharge is realized.
