Abstract
The utility model discloses a pressurization process integrated control device of nitrogen equipment, relating to nitrogen producing equipment. The pressurization process integrated control device comprises a nitrogen storage tank before pressurization, a nitrogen pressurizer and a nitrogen storage tank after pressurization and is mainly and technically characterized in that the main pipeline of the pressurizer is added with a backflow nitrogen compensation bypass which is formed by the sequential connection of a pressure transmitter PT, a check valve V3, a manual gate valve V1 and a pneumatic stop valve V2 and is controlled by a control system. The pressurization process integrated control device not only ensures the running safety of the device, but also solves the problem of frequent equipment stopping caused by the unstable nitrogen suction pressure generated in the old process.
Description
Technical field:
The utility model relates to a kind of equipment of making nitrogen.
Background technology:
Existing nitrogen gas preparing is the air-breathing mode of pulse when working owing to the nitrogen supercharging machine, causes the preceding gas-holder supply pressure fluctation of supercharging very big.When the supercharger inspiratory flow strengthens, fail timely tonifying Qi because of suction end and cause pressure of inspiration(Pi) low excessively, even vacuum state occurs, cause the regular shutdown of equipment.
Summary of the invention:
The nitrogen gas preparing supercharging technology combined control equipment of the regular halting problem of equipment that the pressure of inspiration(Pi) instability that the utility model provides a kind of security that has guaranteed that device moves to solve old technology appearance again causes.
The utility model is achieved by the following technical solution: a kind of nitrogen gas preparing supercharging technology combined control equipment, comprise the preceding gas-holder of supercharging, the nitrogen supercharging machine, gas-holder after the supercharging, its major technique feature is to install backflow tonifying Qi bypass on the supercharger main line additional, and backflow tonifying Qi bypass is successively by pressure unit PT, vacuum breaker V
3, hand sluice valve V
1, pneumatic cut-off valve V
2Be formed by connecting, backflow tonifying Qi bypass is controlled by Controlling System.
The utility model is opened backflow tonifying Qi technology, hand sluice valve V automatically in the equipment pressurization
1Can manually control the backflow flow of air supply it is adjusted to best tonifying Qi state, pressure unit is monitored suction end pressure in real time and sampled signal is transferred to Controlling System, during the gas-holder operating pressure, Controlling System sends instruction pneumatic cut-off valve V before tonifying Qi pressure surpasses supercharging in the work
2Close, so not only guaranteed the security of device operation but also solved the equipment regular halting problem that pressure of inspiration(Pi) instability that old technology occurs causes.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Embodiment:
As shown in Figure 1, this nitrogen gas preparing supercharging technology combined control equipment comprises the preceding gas-holder 7 of supercharging, nitrogen supercharging machine 6, and gas-holder 8 after the supercharging, install backflow tonifying Qi bypass on supercharger 6 main lines additional, and backflow tonifying Qi bypass has pressure unit 1, vacuum breaker V
32, hand sluice valve V
13, pneumatic cut-off valve V
24, Controlling System 5 is formed.In the equipment pressurization, open backflow tonifying Qi technology automatically, hand sluice valve V
1Can manually control the backflow flow of air supply it is adjusted to best tonifying Qi state, pressure unit is monitored suction end pressure in real time and sampled signal is transferred to Controlling System, during the gas-holder operating pressure, Controlling System sends instruction pneumatic cut-off valve V before tonifying Qi pressure surpasses supercharging in the work
2Close, so not only guaranteed the security of device operation but also solved the equipment regular halting problem that pressure of inspiration(Pi) instability that old technology occurs causes.
