Technical field
The utility model relates to a kind of roller kilns typed high temperature air burning device, specifically refers to after the roller kilns quench zone carries out the combustion air heat exchange and heats, the high temperature combustion air is transported to burner, carries out the special technology device of high-temperature air burning, belongs to energy-conserving and emission-cutting technology.
Background technology
HTAC is a kind of brand-new combustion technology of at home and abroad generally applying in recent years.But should have high input by the technology in-house facility, and the transfer valve of one of its key technology, owing to must in certain time interval, realize the frequent switching of air and flue gas, the manufacturing technology difficulty is big, lack service life.Especially the environment at this high dust pollution of roller kilns can't adapt to especially.
Summary of the invention
The utility model provides a kind of roller kilns typed high temperature air burning device; Utilize existing matching used combustion air feed system; With the Cryogenic air of blower fan output, after introducing the quench zone that possesses temperature more than 1000 ° and carrying out heat exchange and heat, through former pipe network high temperature air is transported to each burner again; With easy device, less input, realize the brand-new combustion technology of roller kilns high-temperature air burning.
The technical scheme that the utility model adopted is: installs by controller, and temperature sensor, blower fan, the Cryogenic air pipeline, the Cryogenic air passage, the Cryogenic air pipe arrangement, heat exchanger tube, the high temperature air return pipe, the high temperature air passage, control valve, the high temperature air pipeline constitutes.Blower fan, Cryogenic air pipeline, high temperature air pipeline are original supporting combustion air feed system.
One end of Cryogenic air pipeline is connected with the outlet of blower fan, and the other end connects control valve, and the control valve other end connects the high temperature air pipeline; One end of Cryogenic air passage connects the Cryogenic air pipeline between blower fan and control valve, the other end is extended with some passwaies, and the passway connects an end of Cryogenic air pipe arrangement, and the other end of Cryogenic air pipe arrangement connects heat exchanger tube; One end of high temperature air passage connects the high temperature air pipeline, and the other end is extended with some passwaies, and the passway connects an end of high temperature air return pipe, and the other end of high temperature air return pipe connects heat exchanger tube.
The Cryogenic air pipeline; Cryogenic air passage, Cryogenic air pipe arrangement connect closed Cryogenic air piping, the high temperature air return pipe of forming; The high temperature air passage; The high temperature air pipeline connects closed back and forms the high temperature air piping, and Cryogenic air piping and high temperature air piping are that balanced configuration, symmetry are installed, the number of configured of Cryogenic air pipe arrangement and high temperature air return pipe and the number of configured of heat exchanger tube symmetry; The closed-loop path is realized at two ends through connecting heat exchanger tube, and control valve is divided into Cryogenic air pipeline and high temperature air pipeline with former combustion air pipeline.
Heat exchanger tube passes kiln wall paperback below roller-way, and two ends extend to outside the kiln wall, connects the low temperature piping and the high temperature piping of the Yao Qiang left and right sides respectively; The quantity of heat exchanger tube can be according to the temperature requirement configuration of high temperature air, and temperature requirement is high more, and number of configured is many more, the heat exchanger tube of revolution curved tube shape, and the temperature of acquisition can further improve.
Control valve is magnet controlled, can adjust the aperture of valve disc according to temperature requirement.Controller is installed in the switch board in control room; Temperature sensor is installed in the middle-end of high temperature air pipeline; Control valve, temperature sensor are connected with controller through lead, and controller controls to adjust the aperture of valve valve disc according to the temperature information of temperature requirement and temperature sensor.
Close control valve; The Cryogenic air of blower fan output is intercepted at the Cryogenic air pipeline, and Cryogenic air to each passway, gets into Cryogenic air pipe arrangement, heat exchanger tube by the passway by the Cryogenic air channel allocation; Heat exchanger tube is in high temperature range, and Cryogenic air is heated in heat exchanger tube.Heated high temperature air is transported to the high temperature air pipeline through high temperature air return pipe, high temperature air passage, carries and be assigned to every suit burner by the high temperature air pipeline.When the temperature information of temperature sensor transmission is lower than the setting requirement, controller control and regulation valve continues to cut out; When the temperature information of temperature sensor transmission is higher than the setting requirement, the valve disc of controller control and regulation valve is opened certain angle, and Cryogenic air directly gets into the high temperature air pipeline through control valve, to reduce the temperature of high temperature air.The size of control valve valve disc opening angle is set according to the amplitude of temperature deviation by controller, and temperature exceeds many more, and the angle of unlatching is big more, otherwise then anti-.
When needs obtain the high temperature air of higher temperature; Under the situation of constant low temperature air total flow; Increasing the configuration of heat exchanger tube quantity increases the heating surface area of Cryogenic air, and heat exchanger tube quantity increases, and the passway quantity of Cryogenic air passage is corresponding to be increased; In the corresponding reduction of Cryogenic air pressure of Cryogenic air passway, air is just slack-off at the flow velocity of heat exchanger tube.Heating surface area is big more, and the heated time is long more, and the temperature of acquisition is just high more.In like manner, the heat exchanger tube of revolution curved tube shape, the temperature of acquisition can further improve.
The beneficial effect of the utility model is: with device, less device input easily, realizes the brand-new combustion technology of roller kilns high-temperature air burning, improves the thermal efficiency, and not only energy-conservation but also reduce discharging.
