Problems solved by technology
[0002] A lot of sludge will be produced in people's production and life. These sludges need to be properly treated to reduce environmental pollution. In order to achieve sludge reduction, the drying method is currently the most commonly used to dry sludge. The method has a good sludge drying effect, but it consumes a lot of energy and produces a lot of harmful gases. It is necessary to develop a sludge drying device that saves energy and reduces the emission of harmful gases.

Embodiment Construction
[0025] The present invention will be further described below in conjunction with accompanying drawing
[0026] Such as figure 1 with figure 2 As shown, the sludge drying device of the present invention includes: quicklime and water mixing tank 1, sludge drying reactor 3, lime milk collection tank 11, steam collection cooling system and waste gas treatment system device, quicklime and water mixing The tank 1 is cylindrical and made of heat insulating material. There is a stirring device 16 inside the tank, which can quickly mix quicklime and water to form a fluid milk of lime. The mass ratio of quicklime to water is 1.5:1-3:1; generally It is 2:1; it can ensure the complete reaction between quicklime and water, and taking into account the water loss caused by the evaporation of water vapor, ensure that the milk of lime has a certain fluidity, and the temperature of the milk of lime will not drop due to the addition of too much water. When adding, water is added from the bott...

The invention discloses a sludge drying device, and belongs to the field of sludge treatment equipment. The device comprises a quick lime and water mixing tank used for generating lime milk with fluidity and without heat release; a lime milk collecting tank used for collecting the lime milk after heat release; a lime milk heat release pipe, wherein one end of the lime milk heat release pipe is connected to the quick lime and water mixing tank, and the other end of the lime milk heat release pipe is connected with the lime milk collecting tank, and a lime milk conveying pump is arranged on thelime milk heat release pipe; and a sludge conveying pipe arranged outside the lime milk heat release pipe in a sleeving manner and used for heating and drying sludge by utilizing the lime milk heat release pipe. Quicklime is subjected to an exothermic reaction when encountering water and is subjected to iron-carbon micro-electrolysis to release heat to serve as a drying heat source, and the purpose is to solve the problem of energy required by sludge drying. According to the invention, energy consumption saving and toxic gas emission reduction are realized to the greatest extent, and effectiveand reasonable utilization of resources is realized.
Description
technical field [0001] The invention relates to the field of sludge treatment equipment, in particular to a sludge drying device. Background technique [0002] A lot of sludge will be produced in people's production and life. These sludges need to be properly treated to reduce environmental pollution.
