Abstract
The utility model relates to a nitrogen protection device of an atmospheric storage tank. The nitrogen protection device comprises the atmospheric storage tank, a nitrogen storage tank and a nitrogen sealing cylinder, wherein the nitrogen storage tank is communicated with the top part of the atmospheric storage tank through a first pipeline, the first pipeline is provided with a first electromagnetic valve, nitrogen sealing liquid is stored in the nitrogen sealing cylinder, the nitrogen sealing cylinder is communicated with the top part of the atmospheric storage tank through a second pipeline, a second electromagnetic valve is arranged at one side of the top part of the nitrogen sealing cylinder, and a pressure sensor is arranged at the top part of the atmospheric storage tank and is connected with the first electromagnetic valve and the second electromagnetic valve through a controller. The nitrogen storage tank inflates nitrogen with certain pressure into the atmospheric storage tank through the first pipeline, so that a chemical material is isolated with air so as to avoid the oxidation of the chemical material. When the pressure of the nitrogen in the atmospheric storage tank is over high, the pressure sensor sends out a signal, so that the controller can control the second electromagnetic valve to open, and the nitrogen is exhausted by the second electromagnetic valve, therefore, the nitrogen in the atmospheric storage tank is ensured to be basically stable.
Description
Technical field
The utility model relates to a kind of atmospheric storage tank, particularly a kind of atmospheric storage tank nitrogen protection device.
Background technique
Chemical enterprise is when using atmospheric storage tank to store chemical material, because atmospheric storage tank is communicated with external, material is easily oxidized, and therefore the storage to material brings adverse influence, is subjected to certain narrow limitation during use.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of atmospheric storage tank nitrogen protection device, can avoid material and air catalytic oxidation in the atmospheric storage tank.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of atmospheric storage tank nitrogen protection device, comprise atmospheric storage tank, its innovative point is: also comprise nitrogen storage tank and nitrogen envelope tube, nitrogen storage tank is communicated with the atmospheric storage tank top by first pipeline, on described first pipeline first solenoid valve is installed, and stores the nitrogen sealing liquid in the nitrogen envelope tube, nitrogen envelope tube is communicated with the atmospheric storage tank top by second pipeline, and top one side of described nitrogen envelope tube is equipped with second solenoid valve; Described atmospheric storage tank top is equipped with pressure transducer, and this pressure transducer is electrically connected with first solenoid valve and second solenoid valve by controller.
Further, the side top of described nitrogen envelope tube is provided with nitrogen sealing liquid surge drum, the top of this nitrogen sealing liquid surge drum is communicated with nitrogen envelope tube top by collecting pipe, nitrogen sealing liquid surge drum bottom is communicated with nitrogen envelope tube top by nitrogen sealing liquid reflow pipe, on the nitrogen sealing liquid reflow pipe valve is installed, nitrogen sealing liquid surge drum top has exhaust port.
Advantage of the present utility model is: when the atmospheric storage tank internal pressure reaches controller and during less than the controller setting value through pressure transducer, controller is controlled first solenoid valve and is opened, nitrogen in the nitrogen storage tank replenishes and enters atmospheric storage tank, be full of nitrogen in jar, avoid chemical material and air catalytic oxidation, nitrogen in the atmospheric storage tank is enclosed in the atmospheric storage tank first closed electromagnetic valve when the atmospheric storage tank internal pressure reaches setting value under the effect of nitrogen sealing liquid in nitrogen envelope tube.Because of ambient temperature changes or liquid level goes up when causing that nitrogen pressure in the atmospheric storage tank is too high, controller is controlled second solenoid valve according to pressure sensor signal and is opened, nitrogen is by the discharging of second electromagnetism, when the atmospheric storage tank internal pressure reaches setting value, second closed electromagnetic valve guarantees that nitrogen pressure is basicly stable within the specific limits in the atmospheric storage tank.
In nitrogen envelope tube one side nitrogen sealing liquid surge drum is set, after second solenoid valve is malfunctioning, enter nitrogen sealing liquid surge drum after nitrogen in the nitrogen envelope tube breaks through the nitrogen sealing liquid, discharge, collect and enter in the nitrogen sealing liquid surge drum with the nitrogen sealing liquid that nitrogen is taken out of by nitrogen sealing liquid surge drum top exhaust port.The nitrogen sealing liquid can flow back to nitrogen envelope tube by nitrogen sealing liquid reflow pipe to be continued to use, and avoids the loss of befouling environment and nitrogen sealing liquid.
Description of drawings
Accompanying drawing is the utility model atmospheric storage tank nitrogen protection device structural representation.
Embodiment
As shown in drawings, comprise atmospheric storage tank 1, nitrogen storage tank 2, nitrogen envelope tube 3, first pipeline 4, first solenoid valve 5, second pipeline 6, second solenoid valve 7, pressure transducer 8, controller 9.
One side of above-mentioned atmospheric storage tank 1 is provided with nitrogen storage tank 2 and nitrogen envelope tube 3, and nitrogen storage tank 2 is communicated with atmospheric storage tank 1 top by first pipeline 4, is serially connected with first solenoid valve 5 on first pipeline 4.Store the nitrogen sealing liquid in the nitrogen envelope tube 3, nitrogen envelope tube 3 is communicated with atmospheric storage tank 1 top by second pipeline 6, and top one side of nitrogen envelope tube 3 is equipped with second solenoid valve 7.At atmospheric storage tank 1 top pressure transducer 8 is installed, this pressure transducer 8 is electrically connected with first solenoid valve 5 and second solenoid valve 7 by controller 9, and controller 9 can be controlled the keying of first solenoid valve 5 and second solenoid valve 7 according to the data of pressure transducer 8.
Above the side of nitrogen envelope tube 3, be provided with nitrogen sealing liquid surge drum 10, the top of this nitrogen sealing liquid surge drum 10 is communicated with nitrogen envelope tube 3 tops by collecting pipe 11, nitrogen sealing liquid surge drum 10 bottoms are communicated with nitrogen envelope tube 3 middle parts by nitrogen sealing liquid reflow pipe 12, be serially connected with valve 13 on the nitrogen sealing liquid reflow pipe 12, nitrogen sealing liquid surge drum top has exhaust port 14.When second solenoid valve 7 is malfunctioning when causing nitrogen to discharge atmospheric storage tank 1, nitrogen pressure surpasses the fluid-tight static pressure in the atmospheric storage tank 1, nitrogen in the storage tank just breaks through nitrogen envelope tube 3 interior nitrogen sealing liquids and enters nitrogen sealing liquid surge drum 10, enters atmosphere by the exhaust port 14 on the nitrogen sealing liquid surge drum 10 then.Nitrogen sealing liquid separated recovery in nitrogen sealing liquid surge drum 10 along with nitrogen is mingled with is back in the nitrogen envelope tube 3 by nitrogen sealing liquid reflow pipe 12 and valve 13, has reduced the pollution of environment and the loss of nitrogen sealing liquid.
