Description
Technical field:
The utility model relates to a kind of interlocking system, relates in particular to a kind of paste state bed reactor parking interlocking system.
Background technology:
Fischer-Tropsch synthesizes strong exothermal reaction, its reaction heat mainly shifts out by the recirculated water vaporization of drum, the recirculated water of synthetic drum is by pressing feed pump to provide through boosting in boiler, before and after the unstripped gas stop valve of reactor only has the stop valve valve, pressure reduction is prevented the low interlocking that locking system falls to go here and there, and does not have the interlocking that drum recirculated water interrupts.nominal situation water drum steam production is generally in the 120t/h left and right, if during in a single day recirculated water interrupt, the control personnel can not in time find to cause a dried pot temperature runaway phenomenon to occur, do pot even in time find to process the improper drum that also can cause, if the unexpected fracture of boiler water pump accident jumping car or circulating water pipework will certainly affect the supply of recirculated water, cause drum to do pot, the reactor heat can not in time be removed, reactor batch temperature goes up, catalyst activity strengthens, fischer-tropsch reaction speed continues to accelerate, temperature of reaction continues to go up, so circulation will cause catalyzer micropore carbon distribution inactivation, sintering of catalyst inactivation when serious, even the Fischer-Tropsch Fe-series catalyst can be formed bulk and can't be taken out and cause stopping again completely more catalyst changeout, paste state bed reactor inside has been covered with heat exchanging pipe, and this heat exchanging pipe is that the chuck tubulation is the core technology of paste state bed reactor, and distortion is fatal if temperature runaway causes the heat exchanging pipe material, is equivalent to whole reactor and scraps and can not carry out Chemical Manufacture, reactor stage casing periphery is strainer tube, strainer tube is the device of normally keeping reactor liquid level Extract paraffin body, the screen pack of strainer tube is integral sintered manufacture craft, its order number is that the impact that the um level is easy to be subject to high temperature damages, if the filtration pipe network burns out liquid wax and can not in time extract out, the reactor liquid level certainly will increase, catalyzer is taken reactor out of, heavy oil blackening and affect normal production, and the operation of the lighter's device load down, economic benefit diminish, severe one can't come into operation and directly cause stop changing, and the strainer tube production cost is large, fabrication cycle and the replacing time all long, cause serious economic loss.
The utility model content:
The purpose of this utility model is to provide a kind of a kind of paste state bed reactor parking interlocking system that prevents the security incidents such as paste state bed reactor and the damage of internal activator overtemperature sintering generation.
the utility model is implemented by following technical scheme: a kind of paste state bed reactor parking interlocking system, it comprises drum, paste state bed reactor, the drum water circulating pump, described drum is communicated with described paste state bed reactor by described drum water circulating pump, be provided with the unstripped gas draft tube on described paste state bed reactor, be provided with the unstripped gas stop valve on described unstripped gas draft tube, it also comprises, the deaerated water pressure transducer, deaerated water flow sensor and interlocking controller, be provided with described deaerated water pressure transducer and described deaerated water flow sensor on the deaerated water water inlet pipe of described drum, described unstripped gas stop valve, described deaerated water pressure transducer be connected the deaerated water flow sensor and all be connected with described interlocking controller.
Described drum is more than one.
Described interlocking controller is any one of PLC controller or distribution type control system.
Advantage of the present utility model: prevent that paste state bed reactor and internal activator overtemperature sintering generation from damaging, guarantee that the temperature runaway phenomenon does not occur reactor, can avoid the generation of a large amount of catalyst breakage accidents; Avoided the harmful effect of artificial carelessness or maloperation, erroneous judgement broken belt; The operation decrease temperature and pressure is all slower, has reduced the impact of temperature, pressure to equipment material.Slow cooling can exhaust the CO of inside reactor, prevents that catalyzer is poisoning at low temperatures.
Description of drawings:
Fig. 1 is the utility model integrated connection schematic diagram.
Drum 1, paste state bed reactor 2, drum water circulating pump 3, deaerated water pressure transducer 4, deaerated water flow sensor 5, interlocking controller 6, unstripped gas draft tube 7, unstripped gas stop valve 8, deaerated water water inlet pipe 9.
embodiment: as shown in Figure 1, a kind of paste state bed reactor parking interlocking system, it comprises two drums 1, paste state bed reactor 2, drum water circulating pump 3, deaerated water pressure transducer 4, deaerated water flow sensor 5 and interlocking controller 6, drum 1 is communicated with paste state bed reactor 2 by drum water circulating pump 3, be provided with unstripped gas draft tube 7 on paste state bed reactor 2, be provided with unstripped gas stop valve 8 on unstripped gas draft tube 7, be provided with deaerated water pressure transducer 4 and deaerated water flow sensor 5 on the deaerated water water inlet pipe 9 of drum 1, unstripped gas stop valve 8, deaerated water pressure transducer 4 is connected with the deaerated water flow sensor and all is connected with interlocking controller 6, interlocking controller 6 is any one of PLC controller or distribution type control system.
The course of work: be pumped into paste state bed reactor 2 by drum ebullator 3 from the high-temperature high pressure water 1.85MPa (A) of drum 1,199 ℃.Drum 1 supplementing water is the deaerated water from deaerated water water inlet pipe 9.The interior temperature of paste state bed reactor 2 is to regulate by the pressure of drum 1.Drum 1 pressure raises, and paste state bed reactor 2 temperature raise, drum 1 pressure decreased, and paste state bed reactor 2 temperature reduce.When operation, if paste state bed reactor 2 temperature raise, reduce drum 1 pressure; If paste state bed reactor 2 temperature descend, improve drum 1 pressure.Therefore drum 1 pressure is the thermoregulator important parameter of paste state bed reactor 2.
Deaerated water pressure transducer 4 and deaerated water flow sensor 5 are issued interlocking controller 6 simultaneously with pressure, flow analog signals, interlocking controller 6 judges through logic after receiving signal, if the deaerated water flow satisfies definite deaerated water interruption lower than the pressure difference value of setting value and ductwork pressure and boiler feed water pump discharge simultaneously lower than certain setting value, interlocking controller 6 will send shutdown signal immediately to unstripped gas stop valve 8, and unstripped gas stop valve 8 cuts out simultaneously and stops into unstripped gas.
