Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

Examples

Referring to fig. 1, the present invention provides a technical solution: the utility model provides a clean burner of coal fired boiler, including boiler 1, blast pipe 3, fan 7 and

distributor

9, 1 outer controller 15 that is equipped with of boiler, 1 inside combustion chamber 2 that is equipped with of boiler, 2 connection blast pipes 3 of combustion chamber, 3 covers of blast pipe establish filter 4, filter 4 connects ventilation pipe 5 and back flow 6, back flow 6 communicates with each other with hybrid tube 11, hybrid tube 11 and air-supply line 13 are worn to establish by combustion chamber 2, hybrid tube 11 and air-supply line 13 connection distributor 9, distributor 9 intercommunication biography trachea 8, biography trachea 8 connects fan 7, the lower extreme of fan 7 is equipped with support 14.

The reflux pipe 6 is externally sleeved with a heat preservation device, so that the high-temperature gas transmitted into the reflux pipe 6 can be preserved in heat.

The mixing pipe 11 passes through the first valve 10, and the opening and closing of the mixing pipe 11 can be controlled through the first valve 10.

An air inlet pipe 13 penetrates through the second valve 12, and the air inlet can be controlled through the second valve 12.

The return pipe 6 is arranged through the third valve 16, and the opening and closing of the return pipe 6 can be controlled through the third valve 16.

The overall controller 15 is connected to the first valve 10, the second valve 12, and the third valve 16, and the overall controller 15 can control the on/off adjustment of the first valve 10, the second valve 12, and the third valve 16.

The working principle is as follows: specifically, the fan 7 is opened through the master controller 15, the fan 7 operates to convey air to the distributor 9 through the air conveying pipe 8, the second valve 12 is opened through the master controller 15, the air enters the combustion chamber 2 through the air inlet pipe 13, oxygen in the air enables coal to be fully combusted, the second valve 12 is closed through the master controller 15, high-temperature gas generated by combustion is discharged upwards through the exhaust pipe 3, impurities in the high-temperature gas are filtered out through the filter 4, a part of gas is directly discharged to the atmosphere, the third valve 16 and the first valve 10 are opened through the master controller 15, the rest part of high-temperature gas flows to the mixing pipe 11 through the return pipe 6, and because the heat preservation device is sleeved outside the return pipe 6, the gas in the return pipe 6 is left with residual heat, the air enters from the fan 7, sequentially passes through the air conveying pipe 8 to the distributor 9 and reaches the mixing pipe 11 through the distributor 9, the gas is mixed with the gas in the return pipe 6 and enters the combustion chamber 2, and the gas in the return pipe 6 is kept at the temperature, so that the mixed gas has oxygen and does not need to heat the air, and the mixed gas directly promotes the combustion of coal.

The utility model discloses the beneficial effect who reaches is: adjust the switch of first valve 10, second valve 12 and third valve 16 through total controller 15, adjust the row of the interior air of boiler 1 for hot-air can recycle, and the setting up of filter 4 makes impurity in the gas that the burning produced can filter, carries out clean gaseous emission after the filtration, and overall structure is simple, has higher using value widely.
