Abstract

The utility model relates to a boiler flameout alarm control device, which overcomes the deficiencies that manpower guard consumes more manpower, people is easy to become tired and unsafe factors exists. The device is composed of an infrared sensitive tube flame sensor, a locale flameout detector, an alarm control device in duty room and a solenoid pilot actuated valve; wherein, the flame sensor is arranged on a stove body, the locale flameout detector is composed of a shell body and a circuit plate of a disposal circuit in the shell body, the signal output end of the locale flameout detector is connected with the solenoid pilot actuated valve arranged on the fuel gas or fuel oil supply pipe of the stove and the alarm control device arranged in the duty room to carry on centralizing control, the alarm control device in the duty room is composed of a shell body, and a circuit plate, sonic and optical alarm components and a manual control component arranged in the shell body. The boiler flameout alarm control device provided by the utility model has the beneficial effects that the continuous and automatic monitoring to the flame can be realized, and the double functions of sending a hint and urgency cutting the fuel gas and fuel oil are provided. The infrared sensitive tube has high sensitivity, and the performance is stable and reliable with inerrability, thereby ensuring the burning system to run safely, continuously and efficiently.

Description

The boiler alarm control unit that stops working

Technical field

The utility model belongs to technical field of heating, is specifically related to the anti-unexpected safety device of combustion gas or oil burner.

Background technology

In the oil field, be used for the gas fired-boiler of temperature, hot oil storage tank or pipeline road, quantity is many and dispersion is set, and the boiler that a variety of causes causes is flame-out, not only defeated, oil storage facility are caused adverse influence, and there is serious potential safety hazard in the combustion gas of gathering.If special messenger guard had both needed more labour, be difficult to again make that guarder's every minute and second is continual watches furnace flame attentively, so this kind mode still can not make the people relieved fully.

Summary of the invention

The purpose of this utility model provides the flame-out alarm control unit of a kind of boiler, in case gas fired-boiler is flame-out, at once automatic self-closing gas valve, and send alarm signal to remotely attended chamber, prompting is in time disposed and maintenance, overcomes artificial guard's labor intensive, fatiguability in the past and still has the deficiency of unsafe factor.

Alarm control unit of the present utility model is by ultraviolet light sensing tube flame sensor, on-the-spot misfire detector, night shift room alarm controller, and magnetic valve is formed.Ultraviolet light sensing tube wherein is installed on the body of heater, towards flame.Photosensitive tube signal of telecommunication output line inserts the treatment circuit of on-the-spot misfire detector.On-the-spot misfire detector comprises the treatment circuit circuit board in housing and the housing.The output of on-the-spot misfire detector connects the magnetic valve that is installed on boiler combustion gas or the fuel oil supply line and is positioned on the alarm controller of the night shift room of Centralized Monitoring.The night shift room alarm controller comprises circuit board and sound, light alarm element and the manual control element in housing and the housing.The night shift room alarm controller is installed in monitoring night shift room full position.

Good effect of the present utility model is: use the processing of optical sensor and signal, executive circuit to realize the uninterrupted monitoring to flame, have the dual-use function of prompting and emergency shutdown combustion gas, fuel oil.Ultraviolet light sensing tube is not subjected to the influence of daylight, infra-red radiation, burner hearth high temperature, flame size as flame sensor, and therefore its identification spectrum have characteristics highly sensitive, stable and reliable for performance, that do not have wrong report only to fuel oil, combustion gas sensitivity.The utility model can be widely used in fuel gas such as natural gas or diesel oil is in the combustion system of fuel, guarantee combustion system safety, continuously, efficient operation.

The specific embodiment

Provide embodiment of the present utility model below in conjunction with accompanying drawing.Select U.S. HONYWELL standard ultraviolet light sensing tube 1 as shown in Figure 1 and Figure 2 for use and be installed on the body of heater 2.To be installed in by the circuit board that circuit shown in Figure 3 is made in the housing, and form on-the-spot misfire detector 3 shown in Figure 1, detector 3 is placed on the scene at boiler place.On boiler oil or gas supply line, insert Fig. 1, magnetic valve 4 shown in Figure 2 for cleaning the flow through fuel oil or the combustion gas of magnetic valve, the fuel supply pipe Lu Shangshe filter 7 before magnetic valve.In order when magnetic valve or other members of the utility model break down, to continue the fuel supply of boiler, go out fuel supply spare duct in the parallel connection of magnetic valve two ends, manually-operated gate 7 is arranged on the spare duct.The control output and the electromagnetic valve coil that connect monitor 3 with lead.Will be by the circuit board that circuit shown in Figure 4 is made pack into housing pie graph 1, night shift room alarm controller 5 shown in Figure 2.The input of the output of lead connection detector 3 and alarm controller 5, the power supply of connection circuit, the utility model promptly enters state on duty.

The course of work of the present utility model is: combustion flame is arranged in the stove, ultraviolet light sensing tube has signal of telecommunication output, fray-out of flame, the ultraviolet light sensing tube signal of telecommunication disappears, alarm is accepted flame combustion and is extinguished status signal, export 2 group relay signals simultaneously, master controller receives the flare up fire of detector, sound warning LED alarm lamp flicker of master controller during fray-out of flame, cut off the power supply of giving the front end magnetic valve simultaneously, solenoid closure cuts off the tracheae line, and the data that the preservation signal condition changes on master controller promptly: the correct time of operate as normal recovers in the correct time of the generation of reporting to the police and system.

Claims (1)
