A Limestone Suspension Calcination Equipment

Abstract

The invention discloses limestone suspension calcining equipment, which comprises a heat insulation box, a Venturi tube is fixedly connected to the top of the inner wall of the heat insulation box, and a bottom of the Venturi tube is fixedly connected to the bottom of the inner wall of the heat insulation box. Both sides of the heat insulation box are fixedly connected with a fixed plate, the top of the fixed plate is fixedly connected with a blower, and the output end of the blower is fixedly connected with a shunt pipe, and one end of the shunt pipe runs through the heat insulation box and extends to The inside of the Venturi tube. In the present invention, the limestone powder is fed into the Venturi tube by using the feed port, the limestone powder is better fully calcined through the fan blade stirring and air injection of the agitator, and the air blower drives the shunt tube to make multiple air jets flow in the Venturi tube The spiral rotation greatly prolongs the calcination time of the limestone powder suspended in the air, the exhaust gas is not polluted by the exhaust gas processor, and the calcined limestone is cooled by the cooling jacket and the cooling spray port.

Description

technical field [0001] The invention relates to the technical field of calcination, in particular to limestone suspension calcination equipment. Background technique [0002] In the process of mine processing, a large amount of limestone powder will be produced. Limestone powder is piled up in the mine as mine waste, which occupies a large area, causes waste of resources, and pollutes the environment. Calciner can be used to calcine and reuse limestone powder. The existing calciner has fast feeding speed, low discharging efficiency, and directly discharges high-temperature harmful tail gas into the environment, polluting the environment; [0003] Therefore, there is an urgent need to design a low-cost, slow-down feeding speed, thorough calcination of limestone powder, high discharge efficiency, effective use of waste heat in the tail gas, treatment of the tail gas before being discharged into the environment, reducing the pollution of the tail gas to the environment, energy ...
