Embodiment Construction
[0018] Embodiments of the present invention are further described below in conjunction with accompanying drawings:
[0019] Such as figure 1 As shown, a carbon calciner exhaust gas desulfurization and dust removal method comprises the following steps: (1) heat exchange and cooling: the exhaust gas produced by the carbon calciner 1 enters the waste heat boiler and heat exchanger 4 to realize heat exchange and cooling; (2) desulfurization and dust removal: The cooled exhaust gas enters the desulfurization and dust collector 5 and sprays alkaline solution with the spray system 6 to carry out wet desulfurization and dust removal to obtain purified gas; (3) heating exhaust: the purified gas is heated through the heat exchanger 4 Then it is discharged into the atmosphere through the chimney. The waste heat boiler includes a heat-conducting oil furnace 2 and a steam boiler 3, and the heat-conducting oil furnace 2 and the steam boiler 3 are respectively connected with the carbon calc...

The invention provides a carbon calcining furnace waste gas desulfurizing and dust-removing method and device. The method comprises the steps of heat exchanging and cooling, desulfurizing and dust-removing as well as heating and gas exhaustion. The manufacturing device comprises a carbon calcining furnace and is characterized by further comprising an afterheat boiler, a heat exchanger, a desulfurizing dust remover and a spraying system, wherein the carbon calcining furnace is connected with the afterheat boiler; the afterheat boiler is connected with the heat exchanger; the heat exchanger is connected with the desulfurizing dust remover; the spraying system is fixed on the desulfurizing dust remover; and a gate valve is arranged on each connecting pipeline. According to the invention, heat in high temperature waste gas generated in the carbon calcining furnace is effectively utilized and substances generated by desulfurization and dust removal are recycled, so that energy is saved and emission is reduced; by using the carbon calcining furnace waste gas desulfurizing and dust-removing method provided by the utility model, necessary conditions of desulfurization and dust removal are sufficiently taken into consideration and all steps are organically combined with each other; therefore, the carbon calcining furnace waste gas desulfurizing and dust-removing method provided by the utility model has the advantages of simplicity, practicability, high efficiency, small investment and low operation cost; and secondary pollution is effectively avoided.
Description
technical field [0001] The invention relates to a carbon calciner waste gas desulfurization and dust removal method and a device thereof. Background technique [0002] The calciner for carbon production produces a large amount of high-temperature exhaust gas during production, which contains a lot of heat energy and is accompanied by pollutants mainly including dust and sulfur dioxide. Usually, these waste gases are discharged directly without treatment, causing environmental pollution and climate deterioration. At present, there is a lack of mature and reliable comprehensive treatment methods in China. Contents of the invention [0003] According to the deficiencies in the prior art above, the technical problem to be solved by the present invention is to provide a carbon calciner exhaust gas desulfurization and dust removal method that can effectively utilize the heat of high-temperature exhaust gas and effectively remove harmful substances in the high-temperature exhaus...
