Abstract
The utility model relates to a device that is used for flame detector protection in gas furnace, it includes the flame detector who is connected with gas furnace for blow the cooling air system of cold wind to flame detector probe, with the wind pressure switch of cooling air headtotail, through the control system that wind pressure signal line and wind pressure switch are connected, in addition, control system passes through the flame signal line and is connected with flame detector. The utility model can ensure that the flame detector can work normally at normal temperature and can not accumulate dust.
Description
Technical Field
The utility model relates to a device that is used for flame detector protection in gas furnace is applied to flame monitoring alarm and control in various gas furnace furnaces.
Background
In chemical production devices, gas furnaces are increasingly used. Gas burners typically employ a flame detector to monitor whether the combustible gas within the burner is burning properly. However, the flame detector is often not covered by dust in the hearth or the probe is burned out by high-temperature gas, so that flame signals are displayed abnormally, the furnace is shut down, and great economic loss of a factory is caused.
SUMMERY OF THE UTILITY MODEL
An object of this patent is to provide a maintenance-free, reduce trouble blowing out number of times, in order to realize above-mentioned purpose, the utility model discloses a technical scheme as follows:
the utility model provides a device that is used for flame detector protection in gas furnace, its includes the flame detector who is connected with gas furnace, is used for blowing the cooling air system of cold wind to flame detector probe, the wind pressure switch who is connected with the cooling air system, the control system who is connected through wind pressure signal line and wind pressure switch, in addition, control system passes through the flame signal line and is connected with flame detector.
The cooling air system may include a blower (or fan) and cooling air ducts for supplying air.
Further, the wind pressure switch is arranged on a cooling wind pipeline of the cooling wind system.
During operation, through a wind pressure switch that sets up on the cooling air pipeline, wind pressure switch signal passes to control system, under the boiler normal combustion condition, blow cooling air to flame detector probe through the cooling air system, make flame detector normal work can not save the dust at normal atmospheric temperature, when cooling air system abnormal interruption, report to the police through wind pressure switch low pressure, the signal passes to control system, can in time inspect and maintain cooling air system after the handicraft receives alarm signal, avoid cooling air system down time overlength to lead to flame detector to burn out, reduce unnecessary blowing out. In addition, the control system monitors the working condition of the flame detector through a flame signal wire.
The advantages of the utility model
Through the utility model discloses a device that is used for flame detector protection in gas furnace can make flame detector normal work can not save the dust at normal atmospheric temperature, when cooling air system abnormal interruption, can in time detect by the control system through alarm signal to check and maintain the cooling air system, avoid cooling air system down time overlength to lead to flame detector to burn out, reduce unnecessary blowing out.
Drawings
Fig. 1 is a schematic view of the device for protecting the flame detector in the hearth of the gas furnace according to the present invention.
Detailed Description
The present invention will be further described with reference to the accompanying drawings.
As shown in figure 1, the utility model discloses a device for flame detector protection in gas furnace includes the flame detector 2 of being connected with gas furnace 1 for blow cold air's cooling air system 5 to flame detector 2 probe, the wind pressure switch 4 of being connected with cooling air system 5, through the control system 3 that wind pressure signal line 6 and wind pressure switch 4 are connected, in addition, control system 3 passes through flame signal line 7 and is connected with flame detector 1.
The cooling air system may include a blower (or fan) and cooling air ducts for supplying air.
Further, a wind pressure switch 4 is provided on a cooling wind duct of the cooling wind system 5.
During operation, through a wind pressure switch that sets up on the cooling air pipeline, wind pressure switch signal passes to control system, under the boiler normal combustion condition, blow cooling air to flame detector probe through the cooling air system, make flame detector normal work can not save the dust at normal atmospheric temperature, when cooling air system abnormal interruption, report to the police through wind pressure switch low pressure, the signal passes to control system, can in time inspect and maintain cooling air system after the handicraft receives alarm signal, avoid cooling air system down time overlength to lead to flame detector to burn out flame detector, reduce unnecessary blowing out. In addition, the control system monitors the working condition of the flame detector through a flame signal wire.
While the preferred embodiments of the present invention have been described above, it should be understood that the above description is exemplary and not intended to limit the invention in any way. Changes and modifications may be made without departing from the spirit and scope of the invention, and these changes and modifications are to be considered as within the scope of the invention.
