TECHNICAL FIELD

[0001] The utility model relates to a combustion furnace technical field, specifically relates to a vertical dangerous waste incinerator. BACKGROUND

[0002] The industrial waste generated in the current industrial production process mainly includes solid waste, waste gas and waste liquid.

[0003] Among them, the waste gas is usually treated by the current mainstream waste gas treatment equipment such as TO and RTO equipment. The TO furnace is a direct-fired waste gas treatment equipment, which uses the high-temperature heat after fuel combustion to increase the temperature of the organic waste gas to the reaction temperature to make it oxidize and decompose. The RTO regenerative incinerator uses high temperature to oxidize organic waste gas into carbon dioxide and water.

[0004] Compared with the TO furnace, the RTO regenerative incinerator changes the heat exchanger into regenerative ceramic, and the high-temperature combustion gas and the new incoming waste gas alternately enter the regenerative ceramic for direct heat exchange, so that the heat utilization rate can be increased to more than 90%. The RTO regenerative incinerator has low operating cost and is the main waste gas treatment equipment at present. However, the waste gas treatment equipment cannot treat solid waste and waste liquid.

[0005] And the solid waste and waste liquid are mainly treated by the incinerator. The incinerator uses the combustion of coal, fuel oil, fuel gas and other fuels to high-temperature incinerate and carbonize the objects to be treated to achieve the purpose of disinfection. However, the incinerator cannot treat waste gas.

[0006] Therefore, a new technology is urgently needed to realize the comprehensive treatment of waste gas and waste liquid. INVENTION CONTENTS

The embodiments involved in the present application adopt a vertical furnace body 102, and the external waste liquid and waste gas enter the inside of the vertical furnace body 102 through the waste liquid inlet 104 and the waste gas inlet 106 respectively. Then, the burner 108 fully burns the waste liquid and waste gas mixture to achieve the harmless treatment of the waste liquid and waste gas at the same time. Finally, the residual gas after the harmless treatment is discharged from the vertical hazardous waste incinerator through the waste gas outlet 110.

[0034] In some embodiments, the distance between the burner 108 and the top of the vertical furnace body 102 is less than or equal to 1 / 3 of the total height of the vertical furnace body 102. The distance between the waste gas outlet 110 and the bottom of the vertical furnace body 102 can be less than or equal to 1 / 4 of the total height of the vertical furnace body 102.
