The specific embodiment is with reference to accompanying drawing, the present invention includes hot air boiler, high temperature is with hot equipment 22, multitube Ceramic dust collector 13 and drying plant 15, be provided with the charging aperture 5 and the intake stack 8 that are communicated with burner hearth 6 below the hot air boiler, intake stack 8 is communicated with primary air fan 9, establish the first flue 7 and the second flue 26 in the hot air boiler, establish convection bank 23 in the second flue 26, the two ends of convection bank 23 respectively be arranged on outer the advancing of body of heater, oil-out 25,20 are communicated with, advance, oil-out 25,20 respectively by high temperature circulation pump 24, temperature sensor 21 is communicated with hot equipment 22 with high temperature, and the first flue 7 and the second flue 26 are respectively through MOD 10,20 are communicated with boiler back end ductwork; Back-end ductwork is communicated with chimney 16 through multitube Ceramic dust collector 13, drying plant 15 and air-introduced machine 17, and multitube Ceramic dust collector 13 is provided with temperature sensor 14 with the tube connector of drying plant 15; Back-end ductwork is provided with the blast pipe that is communicated with overfire air fan 12, and blast pipe is provided with Secondary Air MOD 11; The charging aperture 5 that is communicated with burner hearth 6 is communicated with screw feeder 3 and charging blower fan 2 by conveying pipeline 4, and the feed hopper of screw feeder 3 is communicated with bucket elevator 1; Back-end ductwork is provided with the air intake arm, and the air intake arm is connected with the blast pipe of air-introduced machine 17 by standby fan 18.
Workflow of the present invention and operation principle are:
Sanding powder fuel is sent into by bucket elevator 1 in the hopper of screw feeder 2, and fuel falls in the conveying pipeline 4 under the drive of screw feeder 2 motors, and fuel enters burner hearth 6 burnings along conveying pipeline 4 through charging aperture 5 under the effect of charging blower fan 2;
The required air that burns is provided by primary air fan 9, enters burner hearth 6 by intake stack 8; The high-temperature flue gas that burner hearth 6 internal combustion are finished is divided into two under the effect of flue gas partition wall through the upset of burner hearth partition wall, partial fume is by the first flue 7, enter back-end ductwork through the first flue MOD 10, another part flue gas enters back-end ductwork by the second flue 26 through convection bank 23, the second flue MOD 19;
Organic heat carrier after high temperature circulation pump 24, oil-in 25 enter the heat that convection bank 23 absorbs high-temperature flue gas from oil-out 20 again to high temperature with hot equipment 22 heat exchange, enter again high temperature circulation pump 24 after heat exchange is finished and continue to heat;
After first and second flue 7,26 tail flue gas are through 13 dedustings of multitube Ceramic dust collector, for usefulness low temperature hot-air drying device 15, then enter atmosphere through air-introduced machine 17, chimney 16.So the naked light in the flue gas and the dust of larger particles enter drying plant multitube Ceramic dust collector 13 is set, it plays again Secondary Air and the well-mixed effect of flue gas, and temperature sensor 14 can accurately be controlled the temperature that enters drying plant 15 hot blasts.Standby fan 18 is can start when drying plant 15 is out of service;
Whole device is controlled with hot equipment 22 with the temperature of the drying plant 15 of low temperature hot blast with the high temperature of high temperature heat source by temperature sensor 14 and 21 pairs.Temperature sensor 14 control high temperature are with the temperature of hot equipment 22, be the open degree that at first increases the second flue MOD when the temperature of temperature sensor 21 is lower than setting value, next increases the air quantity of primary air fan, the air quantity that increases charging blower fan 3, the rotating speed that increases screw feeder 4 and is used for strengthening and restraints the technological temperature that 23 exhaust gas volumn improves heat carrier by the convection current official and reach setting value; At first reduce the open degree of the second flue MOD when the temperature of temperature sensor 21 is higher than setting value, next reduces the air quantity of primary air fan, the air quantity that reduces charging blower fan 3, the rotating speed that reduces screw feeder 4 and is used for reducing and restraints the technological temperature that 23 exhaust gas volumn reduces heat carrier by the convection current official and reach setting value.It is the open degree that at first increases the first flue MOD 10 that the temperature of temperature sensor 14 is lower than setting value, next increases the air quantity of primary air fan 9, the air quantity that increases charging blower fan 3, the rotating speed that increases screw feeder 4 and reaches the increase exhaust gas volumn, makes it reach setting value thereby increase the temperature that exhaust gas volumn by the first flue 7 improves flue gas; When being higher than setting value, the temperature of temperature sensor 14 at first reduces the open degree of the first flue MOD 10, next reduce primary air fan 9 air quantity, reduce charging blower fan 3 air quantity, reduce the rotating speed of screw feeder 4, start overfire air fan 12, open Secondary Air MOD 11, make the setting value of its technological temperature that reaches for reducing the flue-gas temperature that enters drying plant.
