Abstract
The utility model discloses a coke oven furnace roof interlocking alarm device under gas -blowing engine shut down accident situation, the device is including fan contactor, PLC control system, relay, UPS, air switch, alarm device. The utility model discloses alarm device has been installed on the coke oven furnace roof, when the air -blower is shut down, the fan contactor, PLC control system, the relay feeds back the stopping signal very first time operation scene of coke oven furnace roof rapidly, remind furnace roof operating personnel to withdraw the scene rapidly, strong improvement original only when furnace roof tobacco your writing, the handhole door is washed open even, just can realize the dangerous circumstances after on fire, furthest's reduction injured and fatality, avoid the emergence of industrial accident, and the present invention has strong popularization and application values.
Description
Technical field
The utility model to belong in coking production alarm technique field under gas blower stopping accident state, and it is simple to be specifically related to a kind of structure, can feed back oven top of coke oven interlock alarming device under the gas blower stopping accident state of danger signal in time.
Background technology
Gas blower is the heart level equipment in coking production, be arranged in gas purification operation, under normal circumstances, the raw gas that coke oven produces continuously and smoothly is drawn into rear operation gas cleaning system and purifies by gas blower, makes coke oven produce pressure simultaneously and is stabilized in indication range.When blower fan is shut down because of system dead electricity or other reason; a large amount of coal gas that coke oven produces can not be taken away in time; in stove, gas pressure increases rapidly; port lid will be diffused, upcast lid will be washed open; furnace pressure is released, and the coal gas diffused out diffuses torch (because coke oven temperature is higher) in above-mentioned these liberation ports burning formation.Smoke guiding bogie operation is generally furnished with because fiddling with stove furnace roof; when cleaning section gas blower is shut down suddenly in the state of accident; as coking process furnace roof operator fail to obtain danger signal (especially furnace roof fire exploring hole has opened the smoke guiding bogie deadlock of just in time pre-operation) in the very first time; wait understand be system generation stopping accident time; probably have little time to withdraw scene, serious personnel safety accident will occur.Therefore under researching and developing a kind of gas blower stopping accident state, oven top of coke oven interlock alarming device is necessary.
Utility model content
The purpose of this utility model is to provide a kind of structure simple, can feed back oven top of coke oven interlock alarming device under the gas blower stopping accident state of danger signal in time.
The purpose of this utility model is achieved in that and comprises blower fan contactor, PLC control system, rly., UPS, air switch, warning howler.Described blower fan contactor secondary contact access the input terminus of described PLC control system, the output terminal of described PLC control system accesses the control contact of described rly., described warning device is arranged on oven top of coke oven, described UPS provides power supply for described warning device, described UPS live wire is connected with described air switch, and is connected to the normally opened contact of described rly., and described relay normally open contact is connected with described warning device, described UPS zero line is connected with described warning device, forms alarm set.
The utility model has installed acoustic-optic alarm when gas blower is shut down on oven top of coke oven; blower fan contactor; PLC control system; the stopping signal very first time is fed back to rapidly the operation field of oven top of coke oven by rly.; furnace roof operator are reminded to withdraw scene rapidly; strong improve originally only have when furnace roof tobacco your writing, even port lid wash open, on fire after just can realize dangerous situation, reduce personal injury to greatest extent, avoid the generation of industrial accident.
Accompanying drawing explanation
Fig. 1 is the utility model control principle schematic diagram.
Fig. 2 is the alarm set schematic diagram of the utility model.
Embodiment
Be further described the utility model below in conjunction with accompanying drawing, but must not be limited the utility model by any way, any change done based on the utility model training centre or improvement, all belong to protection domain of the present utility model.
As shown in Figure 1, 2, the utility model comprises blower fan contactor, PLC control system, rly., UPS, air switch, warning device.Described blower fan contactor secondary contact access the input terminus of described PLC control system, the output terminal of described PLC control system accesses the control contact of described rly., described warning device is arranged on oven top of coke oven, described UPS provides power supply for described warning device, described UPS live wire is connected with described air switch, and is connected to the normally opened contact of described rly., and described relay normally open contact is connected with described warning device, described UPS zero line is connected with described warning device, forms alarm set.
The input signal of described PLC control system is fan operation signal, is introduced by described blower fan contactor normally closed contact.
Described PLC control system carries out Logic judgment to all fan operation situations, and when there being fan operation, described PLC control system no-output, when all blower fans are all stopped transport, described PLC control system exports a switch controlling signal.
The output of described PLC control system controls the normally opened contact of described rly., when described PLC control system no-output, described relay normally open contact is in open-circuit condition, and when described PLC control system exports a switch controlling signal, described relay normally open contact closes.
The normally opened contact of described rly. controls alarm set, and when the normally opened contact of described rly. is in open-circuit condition, alarm set is obstructed, and described warning device does not run, and when the normally opened contact of described rly. closes, alarm set is connected, and described warning device runs.
Described UPS provides voltage to be the alternating-current of 220V to described warning device.
Described warning device is combined aural and visual alarm.
Described air switch is in closure state.
principle of work of the present utility model and working process as follows:
The utility model installs acoustic-optic alarm on oven top of coke oven, when gas blower is shut down, rapidly stopping signal is delivered to the warning device of oven top of coke oven, alarm is sounded by Controlling System, warning lamp glimmers, and reminds furnace roof operator to withdraw scene rapidly.
The utility model installs contactor in the operation control loop of gas blower, by the normally closed contact of contactor, the fan operation signal monitored is introduced blower fan PLC control system, by system, Logic judgment is carried out to the running condition of all blower fans, in time having fan operation, PLC no-output, relay normally open contact is in open-circuit condition, and alarm set is obstructed; When all blower fans are all stopped transport time, PLC control system exports a switch controlling signal, the normally opened contact of this signal to specific rly. controls, relay normally open contact closes, loop powers to the combined aural and visual alarm be loaded on coke oven, combined aural and visual alarm alarm is sounded, warning lamp flicker, reminds furnace roof operator to withdraw scene rapidly.
