An adjusting motor of the combustion supporting wind drives more than one adjusting valve sheet of the combustion supporting wind to rotate from 0 DEG to 90 DEG in passage of an adjusting valve body for the combustion supporting wind through a motor adjusting rod of the combustion supporting wind so as to regulate the flow quantity of the combustion supporting wind. A combustion supporting wind chamber is connected with a film box type gas flow adjusting device through an air burning proportion pressure guiding pipe, and the film box type gas flow adjusting device controls the gas flow in the gas adjusting valve body. The utility model uses PID data to calculate so as to realize the pressure guiding type proportion adjusting control of the combustion supporting wind and the gas, and the utility model can cause the pressure of the combustion supporting wind and the gas to reach best proportion so that the gas can be completely burnt regardless of the change of the combustion supporting wind pressure or the gas pressure.
Description
Technical field
The utility model relates to a kind of used for industrial furnace gas burner, is specifically related to a kind of pilot proportion expression burner.
Background technology
Existing used for industrial furnace gas burner uses artificial manual adjustments mode relatively backward regulating combustion gas and the combustion air mixing ratio modes such as adjusting or motorized adjustment manually that adopt more, not only wastes time and energy, and regulates inaccurate.What the mode of use motorized adjustment was more is to adopt electronic ratio to regulate control, promptly on combustion air and gas pipeline, respectively adorn the electronic ratio adjusting valve group of a cover, temperature control unit is established nickel chromium-nickel silicon thermocouple, be attached to the intellectual program temperature control instrument of PID through compensating wire, according to predefined technological parameter, through the digital PID computing, each instrument outputs signal to this temperature-controlled area, the control signal that combustion air pipeline before each burner and the electronic ratio adjusting valve group YE on the gas pipeline are accepted temperature control table, and drive combustion air and the action of combustion gas adjusting butterfly valve.When temperature surpassed design temperature, YE turned down ratio adjusting valve, and burner rating is reduced; Otherwise then situation is opposite fully.This electronic proportion control equipment investment is many, and all is difficult to guarantee that burner is according to the scientific matching normal combustion at combustion air or gaseous-pressure when either party changes.
The utility model content
The purpose of this utility model is to solve the deficiencies in the prior art, provide a kind of no matter combustion air pressure or gaseous-pressure that great variation is arranged, can both make combustion air and gaseous-pressure reach best proportioning and clean-burning gas burner---pilot proportion expression burner.
The technical solution of the utility model is achieved in that pilot proportion expression burner comprises shell, is arranged on the combustion head of described shell front end, the combustion-supporting air compartment that is arranged on enclosure, columnar combustion air spray gun, be arranged on combustion air spray gun rear portion the injection air adjuster, be looped around the annular cylinder shape of described combustion air spray gun outside gas gun, be arranged on the spinning disk that is positioned at combustion air spray gun and gas gun front end in the described combustion head; Described housing is provided with a pilot ratio control device, and described pilot ratio control device is made up of combustion air governor motor, combustion air regulation valve body, bellows-type gas flow adjuster, gas control valve body; Be connected by the air-fuel ratio connecting pipe between described combustion-supporting air compartment and the bellows-type gas flow adjuster.
Needs according to combustion air flow size in the described combustion air regulation valve body are provided with more than one combustion air adjusting valve block, be respectively arranged with combustion air between the passage at each combustion air adjusting valve block place and cut apart plate, described combustion air is regulated valve block keep apart.
Described combustion air governor motor and combustion air are regulated between the valve block and are provided with combustion air motor adjusting rod, described combustion air regulate valve block can be in the passage of combustion air regulation valve body under combustion air motor adjusting rod drives in 0 ° of realization--the rotation of 90 ° of angles.
Whole system adopts pid data to calculate, combustion air and combustion gas are realized pilot formula ratio adjusting control, when the combustion air electric control valve is receiving temperature control instrument when action instruction, gaseous-pressure by with the combustion air pipeline on the conduit that is connected, follow the tracks of combustion air pressure constantly, with combustion gas pilot formula ratio adjusting valve interlock, keep combustion air and gaseous-pressure to reach best proportioning.
The utility model has the advantages that that combustion air and combustion gas ratio are regulated control is sensitive, the scientific matching precision height of its body, no matter combustion air pressure or gas pressure have great variation, can both make combustion air and gaseous-pressure reach best proportioning and fully burn.
