Abstract

The utility model discloses a nitrogen sealed protection system. The nitrogen sealed protection system comprises a plurality of U-shaped branch pipes, a waste gas general pipe, a nitrogen gas valve, a pressure adjusting valve, a PLC (Programmable Logic Controller) automatic control instrument and a liquid storage tank, wherein the U-shaped branch pipes are communicated with the waste gas general pipe; the waste gas general pipe is provided with the pressure adjusting valve; and the nitrogen gas valve and the liquid storage tank are arranged on the waste gas general pipe among the U-shaped branch pipes and the pressure adjusting valve. The nitrogen sealed protection system is stable and reliable to operate and the safety of a production system can be improved.

Description

Nitrogen envelope protection system
Technical field
The utility model relates to a kind of nitrogen envelope protection system.
Background technology
The devices such as the storage tank in industrial production, measuring tank often need to install additional exhaust treatment system, if each storage tank or measuring tank install emission-control equipment individually additional, in concrete practice, be unpractical, also can greatly increase occupation area of equipment, if but storage tank or measuring tank exhaust are concentrated on to waste gas header just there will be following problem: if 1, the liquid solvent in groove overflows and will enter waste gas header and flow into other grooves in other groove Raws are formed to pollution; 2, when negative pressure appears in whole system, extraneous air will enter and in system, produce potential safety hazard.
Utility model content
Technical problem to be solved in the utility model is to overcome the shortcoming of above prior art: a kind of stable and reliable operation is provided, improves the nitrogen envelope protection system of production system security.
Technical solution of the present utility model is as follows: a kind of nitrogen envelope protection system, and it comprises some U-shaped arms, waste gas header, nitrogen valve, pressure-regulating valve, PLC instrument for automatic control, fluid reservoir; Described U-shaped arm and waste gas header are communicated with, and described waste gas header is provided with pressure-regulating valve, and the waste gas header between described U-shaped arm and pressure-regulating valve is provided with nitrogen valve and fluid reservoir.
One end of described nitrogen valve is communicated with waste gas header, and the other end is connected to nitrogen pot.
Described U-shaped arm one end is communicated with waste gas header, and the other end is communicated with storage tank or measuring tank.
The beneficial effects of the utility model are: adopt after the utility model nitrogen envelope protection system, even in the situation that the liquid solvent in storage tank or measuring tank overflows, also can not flow in other grooves solvent in other grooves is formed and polluted; When negative pressure appears in whole system, PLC controls nitrogen valve and opens suction nitrogen; avoid entering of extraneous air to cause system to produce potential safety hazard; because system adopts nitrogen protection; improved the security of production system; adopt PLC automatically to control simultaneously; without operating personnel, stable and reliable operation, maintaining is convenient.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model nitrogen envelope protection system.
In figure, 1, U-shaped arm; 2, waste gas header; 3, nitrogen valve; 4, pressure-regulating valve; 5, PLC instrument for automatic control; 6, fluid reservoir.
The specific embodiment
With specific embodiment, the utility model is described in further details below, but the utility model is not only confined to following specific embodiment.
Embodiment
As shown in Figure 1, a kind of nitrogen envelope protection system, it comprises some U-shaped arms 1, waste gas header 2, nitrogen valve 3, pressure-regulating valve 4, PLC instrument for automatic control 5, fluid reservoir 6; Described U-shaped arm 1 and waste gas header 2 are communicated with, and described waste gas header 2 is provided with pressure-regulating valve 4, and the waste gas header 2 between described U-shaped arm 1 and pressure-regulating valve 4 is provided with nitrogen valve 3 and fluid reservoir 6.
One end of described nitrogen valve 3 is communicated with waste gas header 2, and the other end is connected to nitrogen pot.
Described U-shaped arm 1 one end is communicated with waste gas header 2, and the other end is communicated with storage tank or measuring tank.
Described U-shaped arm 1 is that the shape of falling U is vertical with horizontal plane to be arranged, can guarantee that so U-shaped arm 1 knee is higher than waste gas header 2, when the liquid in storage tank or measuring tank overflows into waste gas header 2, liquid yet can not entered in other grooves the solution of other grooves is formed and polluted by U-shaped arm 1, but flow in fluid reservoir 6, as optimization, fluid reservoir 6 is provided with liquid level sensor, when liquid level exceeds datum level, will give the alarm, avoid overflowing.When system reaches certain pressure, pressure-regulating valve 4 is automatically opened combustion gas to waste gas and is reclaimed or purifier.When negative pressure appears in system, PLC automatically controls nitrogen valve 3 and opens nitrogen protection is provided, and adopts PLC Automatic Control, without increasing operating personnel.
