The pressure stabilizing and reclaiming device can reduce pressure fluctuation to reduce the starting frequency and operating time of a compressor, also reduce nitrogen waste and is conducive to energy conservation and consumption reduction.
Description
Technical field
The utility model relates to a kind of high pressure nitrogen voltage stabilizing recovering device.
Background technique
Nitrogen is through being often used as raw material or shielding gas in industrial processes, and according to actual needs, high pressure nitrogen is stored in pressure pan, and low-pressure nitrogen is stored in low pressure tank.Nitrogen in pressure pan is filled with pressure pan after being produced by nitrogen generator again after compressor supercharging, and low-pressure nitrogen is sent into low pressure tank after being produced by nitrogen generator.On pressure pan, be connected with the supply air line of supplying gas to high pressure nitrogen operative installations and be connected with overflow passage, on overflow passage, connecting relief valve.After elevated pressure nitrogen gas tank superpressure (exceeding the setting value of relief valve), elevated pressure nitrogen is directly disposed in atmosphere by the pressure release of tank deck relief valve, so both causes the waste of nitrogen discharge, has also caused the frequent unlatching of compressor simultaneously, has increased the maintenance cost of compressor.At present, the opening of compressor after elevated pressure nitrogen gas tank superpressure, stop having manually and manipulate, one load operator operate not in time, can not close down timely compressor, tank deck safety valve can continue in open mode, can cause so a large amount of nitrogen to enter in atmosphere, increased the working load of compressor, driving frequently, stop compressor has also increased operator's labor intensity simultaneously.
Summary of the invention
The purpose of this utility model is for above-mentioned deficiency, a kind of high pressure nitrogen voltage stabilizing recovering device is provided, this device energy stable high voltage nitrogen pot pressure, the unlatching frequency that reduces compressor, reduction operator labor intensity reclaim high pressure nitrogen with the reduction energy consumption that economizes on resources simultaneously.
In order to solve the problems of the technologies described above, the utility model provides a kind of high pressure nitrogen voltage stabilizing recovering device with following structure, comprise pressure pan and low pressure tank, pressure pan is communicated with nitrogen gas supply device, on pressure pan, be connected with supply air line and overflow passage, on overflow passage, be connected with relief valve, its structural feature is to be provided with nitrogen recycling pipeline between described pressure pan and low pressure tank, nitrogen recycling pipeline one end is communicated with overflow passage, the other end is communicated with low pressure tank, on nitrogen recycling pipeline, be serially connected with controlling valve of voltage regulation group, on overflow passage, be connected with the pressure transducer of controlling the opening and closing of controlling valve of voltage regulation group.
Described controlling valve of voltage regulation group comprises the mortor operated valve and two main gate valves that are serially connected on nitrogen recycling pipeline, and mortor operated valve occupy between two main gate valves.
On described nitrogen recycling pipeline, be also connected with the looped pipeline road being arranged in parallel with described controlling valve of voltage regulation group, on looped pipeline road, be serially connected with secondary gate valve.
Described nitrogen gas supply device comprises nitrogen generator and compressor, and the suction port of compressor is communicated with nitrogen generator, and the air outlet of compressor is communicated with pressure pan.
Suppose that the nitrogen pressure in existing pressure pan is set in 0.9-1.3MP, if inflate in tank lower than 0.9MP compressor start, if higher than 1.3MP relief valve backed down and carried out exhaust, the gas of discharge has just been wasted.The utility model is owing to being provided with pressure transducer, nitrogen recycling pipeline and serial connection controlling valve of voltage regulation group thereon, therefore can reach following effect: while supposing that pressure transducer detects pressure higher than 0.95MP, sending signal opens controlling valve of voltage regulation group, nitrogen enters low pressure tank through nitrogen recycling pipeline, causes relief valve to open wide exhaust and causes waste to prevent that pressure from continuing to raise; When pressure transducer detects pressure lower than 0.95MP, send signal controlling valve of voltage regulation group is closed, thereby the nitrogen pressure in pressure pan is maintained to 0.9-0.95MP.That is to say, the utility model can maintain the pressure in pressure pan a stable scope, can reduce pressure surge, thereby has reduced open frequency and the operation duration of compressor, and can also reduce the waste of nitrogen, is conducive to save energy and reduce the cost.
