Description

Technical Field

[0001] The utility model relates to the technical field of gas combustion-supporting equipment, in particular to an oxygen-enriched gas combustion-supporting integrated intelligent control device. Background Art

[0002] In the gas combustion system, oxygen-enriched air can be added to achieve the effects of combustion support and energy saving. The two are generally set independently of each other, but there are currently the following problems:

[0003] The common gas pressure of most oxygen-enriched machines is relatively high, and most of them use a single pressure-stabilizing valve for pressure stabilization. When the burner stops firing, the pressure can be stable, but when the burner is ignited to supply oxygen, the pressure is relatively low, and the oxygen-enriched oxygen supply is fixed. For a burner with a two-stage fire, the oxygen-enriched amount cannot be automatically tracked, resulting in the same amount of oxygen being added to the two stages. The oxygen-enriched amount may be relatively high during a small fire, and the oxygen-enriched amount during a large fire is relatively low, which affects the energy-saving effect. At the same time, there is a backfire safety problem. During the operation of the gas burner with oxygen enrichment, if the oxygen-enriched pipeline valve component fails, the gas pipeline valve component fails, or during the debugging process, it is easy to lead the fire source to the inside of the mixed gas (gas + oxygen-enriched) pipeline, which will cause backfire and cause a pipeline explosion accident. For this reason, the utility model proposes an oxygen-enriched gas combustion-supporting integrated intelligent control device that is different from the prior art to solve the above technical problems. Utility Model Content

[0004] In order to improve the above-mentioned problems of poor matching between oxygen-enriched pressure and gas burner, fixed oxygen-enriched oxygen supply, and flashback safety issues, the utility model provides an oxygen-enriched gas combustion-supporting integrated intelligent control device.

[0005] The utility model provides an oxygen-enriched fuel gas combustion-supporting integrated intelligent control device, which adopts the following technical solutions:

[0006] An integrated intelligent control device for oxygen-enriched fuel gas combustion-supporting combustion, comprising a protective shell, an oxygen-enriched supply main pipe is penetrated at the lower end of the interior of the protective shell, an electromagnetic valve, a mechanical pressure-stabilizing valve and a high-fire oxygen-enriched supply valve are sequentially installed at one end of the exterior of the oxygen-enriched supply main pipe, an oxygen-enriched supply branch pipe is connected to the outer wall of the oxygen-enriched supply branch pipe, a low-fire oxygen-enriched supply valve is installed on the outside of the oxygen-enriched supply branch pipe, a non-contact photosensor is fixed to one end of the bottom wall of the inner cavity of the protective shell, a non-contact temperature sensor is fixed to the inner wall of one side of the inner cavity of the protective shell, an intelligent controller is arranged on the outside of the protective shell, and the intelligent controller is electrically connected to the electromagnetic valve, the high-fire oxygen-enriched supply valve, the non-contact photosensor, the non-contact temperature sensor and the low-fire oxygen-enriched supply valve.

[0007] By adopting the above technical scheme, according to the gas burner parameters, the mechanical pressure regulating valve is adjusted to reach the matching oxygen-enriched pressure. When a small command from the burner is received, the solenoid valve and the low-fire oxygen-enriched supply valve are made to work simultaneously. When a high-fire start command is received, the solenoid valve, the low-fire oxygen-enriched supply valve and the high-fire oxygen-enriched supply valve are made to work simultaneously to adjust the oxygen supply. When the intelligent controller receives a temperature exceeding the reference temperature value from the non-contact temperature sensor or receives an ultraviolet signal from the non-contact photosensor, the solenoid valve is automatically cut off to close the oxygen enrichment to achieve the purpose of fire prevention.

[0008] Optionally, both ends of the front side wall of the protective shell are hinged with a switch door body through hinges, and the intelligent controller is fixed on the front side wall of the switch door body.

[0009] By adopting the above technical solution, the components in the inner cavity of the protective shell can be easily repaired and maintained by opening and closing the door.

[0010] Optionally, through holes are provided at the upper ends of both side walls of the protective shell, and hoisting and fixing structures are installed on both sides of the top wall of the inner cavity of the protective shell.

[0011] Optionally, the hoisting and fixing structure includes a hoisting member and a threaded member.

[0012] Optionally, the hanging part includes a hanging block, which is fixed on the top wall of the inner cavity of the protective shell, and a mounting tube is fixed on the bottom wall of the hanging block. A mounting piece with a through hole is movably penetrated through the inner cavity of the mounting tube, and a mounting hole is opened at the end of the mounting piece.

[0013] Optionally, the threaded member includes a threaded tube, which is fixedly embedded in the side wall of the mounting tube, a threaded rod is threadedly penetrated through the inner cavity of the threaded tube, and an end of the threaded rod is rotatably connected to the mounting plate via a bearing.

[0014] By adopting the above technical solution, the two sets of threaded rods are screwed, and under the action of the threaded tube, the mounting plate is pushed to move synchronously in the inner cavity of the mounting tube until it passes through the through hole. Bolts are used to pass through the mounting hole to fix the oxygen-enriched gas combustion-supporting integrated intelligent control device at an appropriate position on the mounting wall.

[0015] In summary, the present invention has at least one of the following beneficial effects:

[0016] First, according to the gas burner parameters, adjust the mechanical pressure regulating valve to achieve the matching oxygen-enriched pressure, so that the oxygen-enriched pressure matches the gas burner;

[0017] Second, when a small command from the burner is received, the solenoid valve is opened after a delay through the intelligent controller, and the small fire oxygen-enriched supply valve is opened at the same time, so that the solenoid valve and the small fire oxygen-enriched supply valve work at the same time. When a high-fire start command is received, the high-fire oxygen-enriched supply valve is opened through the intelligent controller, so that the solenoid valve, the small fire oxygen-enriched supply valve and the high-fire oxygen-enriched supply valve work at the same time, and the oxygen supply is adjusted to ensure energy-saving effect;

[0018] Third, when the intelligent controller receives a temperature exceeding the reference temperature value from the non-contact temperature sensor or receives an ultraviolet signal from the non-contact photoreceptor, it automatically cuts off the solenoid valve to close the oxygen enrichment to achieve the purpose of fire prevention.
