Abstract

The utility model relates to a detection system of the working condition of burner ports of power station boilers. Video probe heads are arranged near each burner port inside a furnace chamber. Signal wires of the video probe heads are connected with a controller. An output terminal of the controller is respectively connected with a monitor and a computer. The detection system of the working condition of burner ports of power station boilers has the advantages that the working condition of the burner ports can be observed timely and clearly, the working process can be adjusted accurately, and image storage can be completed.

Description

Fire is chewed television monitoring device

The utility model relates to the utility boiler detecting devices, and especially fire is chewed the detection system of working condition.

When utility boiler moves,,, prevent serious accident so that take the corresponding protection measure to monitorings in time such as the fire extinguishing of the real property sent out, quick-fried stoves.The monitoring method that adopts mainly contains two kinds at present: a kind of is photoelectric probe monitoring system (FSSS), another kind is television observation system (FTV), though they can play certain monitoring effect, but all exist important disadvantages, chew for a plurality of fire that in every layer of burner hearth, are provided with, monitoring system does not reflect the combustion case that each fire is chewed, for powder situation and ventilation situation.At the ignition phase of boiler, because the ash content of oil is few, visibility height in the stove can clearly be observed the fired state that each fire is chewed.But visibility reduction on the one hand behind the throwing powder, just fully burning so do not observe the working condition that single fire is chewed after throwing powder, can not in time be regulated burning condition when arriving the burner hearth center owing to coal dust on the other hand, improves the combustion position of boiler.

The purpose of this utility model provides a kind ofly can in time, clearly observe each fire and chew working condition, the monitoring device of control burning condition.

In order to achieve the above object, the utility model fire is chewed television monitoring device each fire in burner hearth and near chewing video probe is housed, and the afterbody of video probe is in outside the stove, and the video probe holding wire links to each other with controller, and controller output end links to each other with monitor.

The further improvement that the utility model fire is chewed television monitoring device is that another output of controller links to each other with computer.

The utility model fire is chewed television monitoring device and is had following advantage:

(1) can from monitor, clearly observe confession powder, air distribution and the flame situation that each fire is chewed;

(2) can adjust burning condition timely and accurately according to the combustion case that each fire is chewed, make boiler keep good running status;

(3) can analyze according to the storage image in the computer, find out the reason of fire extinguishing, quick-fried stove.

The utility model is described in further detail below by drawings and Examples:

Fig. 1 chews television monitoring device for the utility model fire and forms schematic diagram;

Fig. 2 is the installation site schematic diagram of video probe on boiler in the monitoring arrangement shown in Figure 1;

Referring to Fig. 1 and Fig. 2, on the water-cooling wall 7 of boiler 1, a plurality of fire are housed and chew 2, chew installation video probe 3 near 2 the water-cooling wall 7 at each (maybe need install) fire, the head of video probe 3 is deep in the burner hearth, afterbody is in outside the stove, the holding wire of video probe 3 links to each other with controller (adopting many merits FSb616) 4, the vision signal of each video probe output is handled through controller 4 and is transported in the monitor 6, on monitor 6, present several fire and chew the live picture of burning, as need one of them fire is chewed and to be examined, the TV signal that controller 4 is just chewed this fire is defeated by monitor 6, and monitor 6 just presents only width of cloth picture that this fire is chewed combustion position.Controller 4 also links to each other with computer 5, and computer 5 carries out logical process with the signal of input, gives the alarm according to imposing a condition or instructs, and adjusts fire and chews 2 combustion position, and store image termly.

Claims

1, a kind of fire is chewed television monitoring device, has detector, controller, it is characterized by each fire chew near video probe is housed, the afterbody of video probe is in outside the stove, the video probe holding wire links to each other with controller, controller output end links to each other with monitor.

2, fire according to claim 1 is chewed television monitoring device, it is characterized by another output of controller and links to each other with computer.
