Description
Technical field
The utility model relates to the automatic control technology field, especially relates to the hybrid tamping coke furnace coal gas commutation of Coal Chemical Industry supervisory system.
Background technology
Tamping coke furnace coal gas exchange monitoring system almost all is an independently operation control system in the existing coal chemical industry enterprises, guards operation (people is established in general per tour) so must establish the special messenger, and frequent operation (operation in per 30 minutes once).Although can realize automatic control, performance is not to stablize very much, is manual control mostly.
Tamping coke furnace must be provided with relatively independent instrument control system simultaneously, monitors whole coke oven operation condition.By this system's control furnace temperature, collecting main pressure, coal gas diffusion etc.But each coal gas commutation is equivalent to of short duration cut-out and advances burner hearth firing tunnel in coking furnace pipeline, so that overstocks in the firing tunnel in coking furnace pipeline, therefore " firing tunnel in coking furnace terminal pressure " can rise to about 8.0Kpa moment, pressure is between 0.5Kpa～1.7Kpa when normal; Collecting main pressure is raised to more than the 200Pa, reaches sometimes 300Pa, and normally between 80～100Pa, pressure can recover (probably needing 10 seconds) gradually after continuing commutation end in about 20 seconds.But the coke oven Automatic-heating that instrument control system controls remains at about 8.0Kpa according to processing requirement " firing tunnel in coking furnace terminal pressure ", otherwise adjust the firing tunnel in coking furnace terminal pressure by the aperture of control loop gas regulator rapidly, make it to remain on about 8.0Kpa.So instrument control system thinks that " firing tunnel in coking furnace terminal pressure " is too high and close " firing tunnel in coking furnace variable valve " by mistake, even Guan Wanhou " firing tunnel in coking furnace terminal pressure " can fall.And after the coal gas commutation is finished, the firing tunnel in coking furnace terminal pressure may reduce to 0 moment, and firing tunnel in coking furnace pipe distal portion moment may occur without the fuel phenomenon, thereby affects temperature in the burner hearth, and then Coke Quality exerts an influence the instruction that instrument control system sends out again the firing tunnel in coking furnace variable valve immediately.So repeatedly cause commutating prolongs time of recovery at every turn, and technique is had a negative impact again; Collecting main pressure also is like this.When collecting main pressure surpassed 250Pa, coal gas diffusion is automatically operation just.Therefore can cause very large negative impact to instrument control system during the coal gas exchange, and two systems all are Controlling System independently, are difficult to realize time lock and data sharing.Therefore when instrument control system is difficult to solve the coal gas commutation on the coke oven Automatic-heating can cause, collecting main pressure is regulated automatically and the impact of coal gas diffusion control.
The utility model content
The purpose of this utility model is to provide a kind of hybrid tamping coke furnace coal gas commutation supervisory system, and this system need not special messenger's monitoring, can make gas switch supervisory system and instrument control system realize certain " time lock " and " data sharing " simultaneously.And two cover system again can relatively independent control and do not destroy the function of original system.
The utility model is realized by following technical proposals.
Hybrid tamping coke furnace coal gas commutation supervisory system comprises the coal gas commutation supervisory system supporting with tamping coke furnace exchange board hydraulic efficiency system, and described coal gas commutation supervisory system connects respectively instrument control system and on-the-spot commutating device.
Further, described coal gas commutation supervisory system comprises interconnective hydraulic efficiency system and electrical system.
Further, the state instruction button of the start-stop button of the push button of described electrical system, pump, various magnetic valves links to each other with the supervisory system of instrument control system.

Description of drawings
Fig. 1 is the utility model frame principle figure.
Embodiment
Below in conjunction with drawings and Examples the utility model is described further.
As shown in Figure 1, hybrid tamping coke furnace coal gas commutation supervisory system comprises the coal gas commutation supervisory system supporting with tamping coke furnace exchange board hydraulic efficiency system, and coal gas commutation supervisory system connects respectively instrument control system and on-the-spot commutating device.
Wherein, coal gas commutation supervisory system comprises interconnective hydraulic efficiency system and electrical system.
The state instruction button of the push button of electrical system, the start-stop button of pump, various magnetic valves links to each other with the supervisory system of instrument control system.
In the native system, take instrument control system as pure operating system, the gas switch supervisory system is executive system, with the forward and reverse action button of start-stop button, gas valve, the forward and reverse action button of exhaust gas valve of the hydro-pump of gas switch supervisory system, gas valve is forward and reverse and the indication of mid-way state, the forward and reverse condition indicative signal of waste gas each in parallel one the road deliver to instrument control system.In instrument control system configuration, programme according to crude gas exchange board supervisory system hydro-pump, gas valve and exhaust gas valve operation logic, in the monitored picture configuration of instrument control system, add simultaneously coal gas commutation monitored picture, that preferably this flow process picture is done is consistent with crude gas exchange board monitor system operation table top, namely realizes the coal gas commutation by the respective pump in the commutation of the coal gas in the operation instrument control system monitored picture and valve etc.And be easy to realize automatic control.Need not so ad hoc coal gas commutation worker, and be convenient to instrument control monitoring personnel and check coal gas commutating device operation condition.
Just realize simultaneously " time lock " and " data sharing " that coal gas commutation beginning and the two cover system short period of time of finishing are interior.Certainly crude gas commutation supervisory system still can be used, and can be used as the reserve maintenance and uses.Automatic-heating, collecting main pressure control, coke oven gas discharge in instrument control system add two interlocking switches in programming, with hydro-pump start-stop button interlocking in the coal gas commutation monitored picture (because during each commutation, the first step operation is exactly the primer fluid press pump, and the final step operation is the stop solution press pump).Interlocking switching Automatic-heating, collecting main pressure control, coal gas diffusion are manually control when the primer fluid press pump; To switch Automatic-heating, collecting main pressure control, coal gas diffusion be automatically adjusting when the stop solution press pump was interlocked after 10 seconds.Certainly general inoperation firing tunnel in coking furnace variable valve, collecting main pressure variable valve and start coke oven gas discharge during the coal gas commutation are because the firing tunnel in coking furnace terminal pressure, collecting main pressure value " wrong " can't be as operating basis.So instrument control monitoring personnel do not need to do any operation.
According to required system and different, but only be to add the operation programming of coal gas switch operation button and interlocking switch all instrument control systems that programme to realize for the programming of instrument control system, and programming is also special simple, does not just do too much elaboration at this; Equally for the start stop signal of No. one pump in parallel and each push-botton operation signal to instrument control system, the switching value signal connection of only pressing instrument control system gets final product.
Above content is in conjunction with concrete preferred implementation further detailed description of the utility model; can not assert that embodiment of the present utility model only limits to this; for the utility model person of an ordinary skill in the technical field; without departing from the concept of the premise utility; can also make some simple deduction or replace, all should be considered as belonging to the utility model and determine scope of patent protection by claims of submitting to.
