Description
Technical field
The present invention relates to a kind of fender guard and method of Storage Tanks Combustible Liquid.
Background technology
Combustible liquid; as oil product, alkane, organic oxygen compound etc.; Storage Tanks Combustible Liquid gas phase is often in blast atmosphere; explode to prevent Storage Tanks Combustible Liquid gas phase; at present the most conventional most actv. way is exactly the method adopting gas phase nitrogen protection, constantly supplements nitrogen, along with the operation of storage tank from storage tank breathing valve; nitrogen ceaselessly fills into and breathes out, and makes gas phase in tank keep anaerobic state.Oil product storage tank capacity conventional is at present 5000-10000 cubic meter, and therefore, adopt this kind of method comparatively large to the demand of nitrogen, the enterprise operating cost not plentiful to nitrogen is higher, by investigation, and the cost about 1 yuan of 1 cubic meter nitrogen in refinery.Therefore conventional approach will cause a large amount of nitrogen wastes at present, increase enterprise operation cost.Oil product storage tank gas phase is often in blast atmosphere, and in order to prevent oil product storage tank gas phase from exploding, most actv. way is exactly the method adopting gas phase nitrogen protection, supplements nitrogen from storage tank breathing valve, and along with storage tank runs, nitrogen ceaselessly fills into and breathes out.This operation scheme is for the operation of whole tank field, and nitrogen use amount is huge, and the nitrogen of exhalation contains saturated organic volatile, and this will cause a large amount of nitrogen wastes, and increase enterprise operation cost, the tail gas simultaneously containing organic volatile is by contaminated environment.And once breathing valve et out of order, this runs causing the storage tank of whole tank field under the state of superpressure or negative pressure, very easily causes storage tank to be taken out the flat or breakage that builds the pressure.Once presence of fire, this certainly will increase the risk of flame propagation, fire spread.
CN201410613961 relates to a kind of method protecting storage tank safety and environmental protection, by adopting a kind of method protecting storage tank safety and environmental protection, the gas that liquid in storage tank self produces is passed through gas main, appendix enters compressor, gas is stored in expansion tank by compressor pressurizes, as a part for positive pressure protection gas, when the gas stored in expansion tank does not meet the positive pressure protection of each storage tank, the nitrogen from nitrogen inlet pipeline is used to supplement, when expansion tank internal pressure exceedes design pressure, torch or burning is sent by reduce internal heat torch or incinerator pipeline by excessive gas.CN201320356393 relates to a kind of nitrogen pressure control system for chemical drum, disclose a kind of nitrogen pressure control system for chemical drum, described system comprises the minute-pressure type sensor be arranged in storage tank, be arranged on the gulp valve that described storage tank upper end is connected with described storage tank, blow off valve, described gulp valve and check valve, filter, blowdown valve, pressure regulating valve is connected in series, described pressure regulating valve is connected with nitrogen pot, described minute-pressure type sensor according to the pressure in storage tank by signal transmission to PLC, the closure or openness of described PLC gulp valve and blow off valve according to received signal control.CN201120095334 relates to a kind of nitrogen protection device of atmospheric storage tank; comprise atmospheric storage tank; also comprise nitrogen storage tank and nitrogen sealed tube; atmospheric storage tank top is provided with pressure sensor; this pressure sensor is connected with the first electromagnetic valve and the second electromagnetic valve by controller, ensures the basicly stable of nitrogen in atmospheric storage tank.
Above-mentioned patent monitors nitrogen content by pressure sensor, and then control tonifying Qi and the exhaust of nitrogen, and pressure is maintained in the scope of setting.But whether storage tank is in gas phase blast atmosphere in fact only to rely on pressure accurately to ensure, high to the sealing requirements of storage tank itself, leaks, or for there is the storage tank of breathing valve, then there is certain potential safety hazard if occur.And only control to a certain extent, decrease nitrogen use level, still need to consume a large amount of pure nitrogen gas.And the unresolved pollution of above-mentioned patent more greatly, is easily taken out flat, that safety is poor problem.
The present invention solves this problem targetedly.
