Summary of the invention
The purpose of this utility model provides a kind of soot blower that can in time clear up on dust stratification on the heat-conducting oil pipes, the easy to operate boiler.
Technical solutions of the utility model are finished like this, soot blower on the boiler, comprise switch board, convection cell, the compressed air surge tank, pipeline, be provided with heat-conducting oil pipes in the convection cell, be provided with control system in the switch board, the magnetic valve two ends by pipeline respectively with the compressed air surge tank, the air inlet of soot blower connects, the gas outlet that is located at the soot blower in the convection cell is relative with heat-conducting oil pipes, be provided with pressure transmitter between compressed air surge tank and the control system, pressure transmitter is connected with the compressed air surge tank, and control system is controlled opening and closing of magnetic valve according to the signal of pressure transmitter feedback.Also can manually control opening and closing of magnetic valve according to this signal.
Be provided with infrared radiation detection apparatus in the convection cell, infrared radiation detection apparatus is mainly for detection of the dust stratification thickness on the heat-conducting oil pipes in the stove, infrared radiation detection apparatus constantly feeds back to control system with detected dust stratification thickness signal, and control system is controlled opening and closing of magnetic valve according to the signal of infrared radiation detection apparatus feedback.
Described hand control valve two ends are connected with the air inlet of compressed air surge tank gas outlet, soot blower respectively by pipeline.
The gas outlet of described soot blower is 250mm to the distance of heat-conducting oil pipes.Described soot blower is iron palladium formula soot blower, and iron palladium formula soot blower is provided with arms of gas outlet and forms with the person in charge who is provided with air inlet by several that are connected with the person in charge.
Technique effect of the present utility model is: because the utility model can in time control to adjust valve according to the dust stratification thickness situation on the heat-conducting oil pipes and open, under the effect of air stream, the dust stratification on the heat-conducting oil pipes is blown away, heat-conducting oil pipes is heated evenly, guaranteed that heat-conducting oil pipes is difficult for coking, improved stability and the security of heat conducting oil boiler in the middle of operation.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
By reference to the accompanying drawings the utility model is described in further detail, the soot blower of this heat conducting oil boiler, this covering device can utilize the compressed air in heat conducting oil boiler bag-type dusting district that power is provided, be connected with compressed air surge tank 5 by pipeline 3, magnetic valve 2,10 two ends by pipeline respectively with compressed air surge tank 5 gas outlets, the air inlet of iron palladium formula soot blower connects, the gas outlet that is located at the iron palladium formula soot blower in the convection cell 8 is relative with heat-conducting oil pipes 9, be provided with pressure transmitter 4 between compressed air surge tank 5 and the switch board 1, pressure transmitter 4 is connected with compressed air surge tank 5, and the control system in the switch board 1 is controlled magnetic valve 2 according to the signal of pressure transmitter 4 feedbacks, 10 opening and closing.After compressed air surge tank 5 reaches certain pressure, pressure transmitter 4 is passed to control system in the switch board 1 with signal, control system is made feedback to signal, under the situation that the pressure that stays for some time remains unchanged, control system is sent instruction, and control magnetic valve 2,10 is opened, compressed air in the compressed air surge tank 5 enters iron palladium formula soot blower by pipeline, the air stream that comes out from iron palladium formula soot blower blows to heat-conducting oil pipes 9, and the dust on the heat-conducting oil pipes 9 is blown away, and realizes blowing grey effect.
Described iron palladium formula soot blower is provided with arms 14 of gas outlet and forms with the person in charge 13 who is provided with air inlet by several that are connected with the person in charge 13.After compressed air entered iron palladium formula soot blower, several gas outlets on the iron palladium formula soot blower purged heat-conducting oil pipes simultaneously, had increased greatly to blow grey area and blow grey efficient.
Blow ash control effect in order further to improve, can establish a cover checkout gear again, infrared radiation detection apparatus 7 is set in convection cell 8 exactly, infrared radiation detection apparatus 7 is for detection of the dust stratification thickness control on the heat-conducting oil pipes, infrared radiation detection apparatus 7 constantly feeds back to control system in the switch board 1 with detected dust stratification thickness signal, and control system is controlled magnetic valve 2,10 opening and closing according to the signal of infrared radiation detection apparatus 7 feedbacks.During work, infrared radiation detection apparatus 7 feeds back to control system with detected dust stratification thickness signal, after dust stratification reaches certain thickness, control system is sent instruction, control magnetic valve 2,10 is opened, compressed air in the compressed air surge tank 5 enters iron palladium formula soot blower by pipeline, and the air stream that comes out from iron palladium formula soot blower blows to heat-conducting oil pipes 9, and the dust on the heat-conducting oil pipes 9 is blown away.
The pipe fitting that enters in the heat conducting oil boiler preferably adopts resistant to elevated temperatures stainless steel.The gas outlet of soot blower is 250mm to heat-conducting oil pipes 9 optimum distances.When the detected signal of any one checkout gear in this device satisfies condition, magnetic valve 2,10 is opened, compressed air enters iron palladium formula soot blower by pipeline, is blown into heat conducting oil boiler convection cell 8 by iron palladium formula soot blower, reaches the dust effect of removing on the heat-conducting oil pipes 9.
When preventing that magnetic valve 2,10 from breaking down, when causing iron palladium formula soot blower cisco unity malfunction, by the operate as normal that hand control valve 11,12 guarantees soot blower is set. Hand control valve 11,12 two ends are connected with the air inlet of compressed air surge tank 5 gas outlets, iron palladium formula soot blower respectively by pipeline.When the detected signal of any one checkout gear in this device satisfies condition and magnetic valve when breaking down, when needing perhaps that manually ash is blown in control, can open hand control valve 11,12.Maintenance also can arrange control valve 6 at compressed air surge tank 5 for convenience.
