Problems solved by technology

[0003] The existing cement kiln will generate a lot of heat when it is in use, and when the heat is cooled when the residual temperature is recovered, water vapor will be generated, and an additional water vapor separation device needs to be installed, but the installation cost is relatively high, and the use effect is not good, and During the sludge drying process, the internal sludge cannot be dispersed, resulting in insignificant drying effect of the sludge

Abstract

The invention discloses a gas circulation type cement kiln waste heat drying device. The device comprises a drying box body, a cement kiln and an inner cavity. An operator pours sludge into the drying box body through a feeding door, an induced draft fan can discharge waste heat in the cement kiln into side cavities through a hot air pipe, the two sets of side cavities are communicated, hot air is evenly discharged into the inner cavity through air outlet holes, discharging is even, after drying is completed, the hot air enters a separation barrel through an air outlet pipe, an evaporator is arranged on one side of a first heat regenerator, a second heat regenerator is arranged on one side of the evaporator, and a condenser is arranged on one side of the second heat regenerator. Through cooperation of the separation barrel, the first heat regenerator, the evaporator, the second heat regenerator and the condenser, liquid water steam can be discharged out of the barrel through a condensate water outlet, hot air and water steam can be conveniently separated, the installation cost is low, separated air returns to the cement kiln again through an air inlet pipe, gas can be conveniently recycled, and the production cost is reduced.

Description

technical field [0001] The invention relates to the technical field of cement kilns, in particular to a gas circulation type cement kiln residual temperature drying device. Background technique [0002] Cement rotary kiln belongs to building material equipment and is a kind of lime kiln. Rotary kiln can be divided into cement rotary kiln, metallurgical chemical rotary kiln and lime rotary kiln according to different processing materials. Cement rotary kiln is the main equipment of cement clinker dry process and wet process production line. At present, the methods of batch treatment of urban domestic sludge are generally physical methods and biochemical methods. The physical method is generally dry treatment, that is, to remove sludge Most of the water contained in it will be harmlessly treated or converted to other uses for the remaining slag, such as making cement and making bricks. Compared with biochemical treatment, physical drying treatment has significant advantages,...
