Description
Technical field
The utility model relates to technical field of chemical, is specifically related to a kind of interlock protection mechanism stopping fierce runaway reaction.
Background technology
At present, chemical enterprise run into reactor overtemperature, superpressure and out of control time, general settling mode to pour into or by pumping suction reaction terminating agent from still mouth (or funnel), by terminating reaction in advance, solves runaway condition, occurs to avoid explosion accident.But during runaway reaction, high temperature produces together with high pressure, if directly pour terminator into from still mouth (or funnel), still internal cause pressure is large, and gas can go out reactor, causes personnel to injure; And by pumping suction, effect is relatively better, but speed is slow, then cannot suction when in still, pressure is larger, still there is great risk.
Utility model content
For the deficiencies in the prior art, the utility model provides a kind of interlock protection mechanism stopping fierce runaway reaction.
Technical solutions of the utility model are as follows:
Stop an interlock protection mechanism for fierce runaway reaction, comprise terminator groove, reactor, condenser, waste gas header and interlock control system, described interlock control system is by pneumatic operated valve one, pneumatic operated valve two, pneumatic operated valve three, pneumatic operated valve four and pneumatic operated valve five are formed, the bypass outlet at described reactor top is connected with the entrance and exit pipeline of condenser by pipeline respectively with reflux inlet, the waste gas outlet pipeline of described condenser is divided into two, wherein one is connected with waste gas header through pneumatic operated valve one by pipeline, another by pipeline through check-valves, be divided into two-way again after pneumatic operated valve two, pipeline of leading up to is connected to the entrance on terminator groove top through pneumatic operated valve three, pneumatic operated valve four of separately leading up to is connected with waste gas header, the outlet of described terminator bottom land end by pipeline through pneumatic operated valve five, hand valve is connected with the terminator entrance on reactor top, and when runaway reaction, interlock control system closes pneumatic operated valve one, pneumatic operated valve four, opens pneumatic operated valve two simultaneously, pneumatic operated valve three, pneumatic operated valve five.
The beneficial effects of the utility model are: when the emergency of runaway reaction occurs; only need to start interlock protection by interlock control system; namely pneumatic operated valve one, pneumatic operated valve four is closed by interlock control system; open pneumatic operated valve two, pneumatic operated valve three, pneumatic operated valve five simultaneously; the high pressure in reactor is utilized to be pressed in reactor by the terminator in terminator groove; thus in advance reaction is terminated; solve runaway condition; comparatively prior art; blowdown speed is fast, effective; effectively prevent the generation of explosion accident, reduce security risk.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
Wherein: 1, hand valve; 2, pneumatic operated valve five; 3, terminator groove; 4, pneumatic operated valve three; 5, pneumatic operated valve four; 6, waste gas header; 7, pneumatic operated valve two; 8, check-valves; 9, pneumatic operated valve one; 10, condenser; 11, reactor.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Consult Fig. 1, a kind of interlock protection mechanism stopping fierce runaway reaction, comprises terminator groove 3, reactor 11, condenser 10, waste gas header 6 and interlock control system, described interlock control system is by pneumatic operated valve 1, pneumatic operated valve 27, pneumatic operated valve 34, pneumatic operated valve 45 and pneumatic operated valve 52 are formed, the bypass outlet at described reactor 11 top is connected with the entrance and exit pipeline of condenser 10 by pipeline respectively with reflux inlet, the waste gas outlet pipeline of described condenser 10 is divided into two, wherein one is connected with waste gas header 6 through pneumatic operated valve 1 by pipeline, another by pipeline through check-valves 8, be divided into two-way again after pneumatic operated valve 27, pipeline of leading up to is connected to the entrance on terminator groove 3 top through pneumatic operated valve 34, pneumatic operated valve 45 of separately leading up to is connected with waste gas header 6, the outlet of described terminator groove 3 bottom by pipeline through pneumatic operated valve 52, hand valve 1 is connected with the terminator entrance on reactor 11 top, and when runaway reaction, interlock control system closes pneumatic operated valve 1, pneumatic operated valve 45, opens pneumatic operated valve 27 simultaneously, pneumatic operated valve 34, pneumatic operated valve 52.
Principle is, when the temperature that staff observes in reactor 11 is gentle press through high time, namely during runaway reaction, interlock protection is started by interlock control system, namely pneumatic operated valve 1 is closed by interlock control system, pneumatic operated valve 45, open pneumatic operated valve 27 simultaneously, pneumatic operated valve 34, pneumatic operated valve 52, meanwhile open hand valve 1, utilize pressure balance principle, gases at high pressure in reactor 11 pass through the waste gas outlet pipeline of condenser 10 through check-valves 8, pneumatic operated valve 27, pneumatic operated valve 34 enters terminator groove 3, under the effect of gases at high pressure, terminator in terminator groove 3 passes through the outlet conduit of terminator groove 3 bottom through pneumatic operated valve 52, hand valve 1 enters in reactor 11, thus in advance reaction is terminated, solve runaway condition, effectively prevent the generation of explosion accident.
Above-mentioned drawings and Examples are only for illustration of the utility model, and any art those of ordinary skill to its suitable change done or modification, or is used other flower pattern instead and made this technical change, all should be considered as not departing from the utility model patent category.
