The invention relates to a converter 
coal gas non-water dust removing equipment, which comprises a converter, a radiant type waste-heat boiler, an adjusting valve, a 
cyclone dust remover, a bag-type dust remover, a 
coal gas temperature controlling device, a flow meter, a main induced draft fan, a three-way valve, an emission 
chimney, a rotary water seal, a U-shaped water seal, and a 
coal gas tank. The invention is characterized in that a 
convection type waste-heat boiler is connected between the outlet position of the radiant type waste-heat boiler and the adjusting valve, and the 
convection type waste-heat boiler is composed of a 
settling chamber, a heat exchange component, a baffle plate, a box body, and an ash discharging opening. A process method comprises the steps that converter 
coal gas comes into the 
convection type waste-heat boiler via radiant type waste-heat boiler after 
recovery waste heat, the gravitational 
settling is performed to come into the adjusting valve, and the bag-type dust remover, etc to perform dust fining removal after the 
recovery waste heat, the emission is performed through the three-way valve or the converter 
coal gas comes into the 
coal gas tank to perform coal gas 
recovery, and the invention has the 
advantage that the 
energy consumption is reduced through recovering 
heat energy.
