Abstract

The invention provides a sludge treatment device using waste heat of a boiler and a treatment process thereof, relates to a sludge treatment device using waste heat of a boiler and improvement of a treatment process thereof, in particular to a sludge treatment device using waste heat discharged by fume of a boiler and a treatment process thereof. The sludge treatment device comprises the boiler, wherein the boiler is respectively connected with a coal conveying belt device and a fume discharge treatment device. The sludge treatment device is characterized in that the fume channel of a fume discharge device is connected with a drier through an induced draft fan and a cyclone separator; the side of the drier is connected with a sludge storage warehouse; the drier and the bottom of the cyclone separator are connected with a finished product warehouse through a belt conveyer; and the finished product warehouse is connected with the coal conveying belt device through a spiral conveyer. The treatment process comprises the following steps: firstly, introducing fume in the fume discharge channel of the boiler into the drier to dry sludge; and sending tail gas in the dried sludge into the fume discharge channel of the boiler, and then returning the residual sludge to the boiler to participate in combustion.

Description

Technical field: [0001] The invention relates to the improvement of a device for treating sludge by using boiler waste heat and a treatment process. Background technique: [0002] Domestic thermal power plants used to treat boiler flue gas exhaust by simply eliminating smoke, dust, desulfurization and purification, and part of the preheated air was used as secondary air to enter the boiler for combustion; the remaining hot smoke with a certain temperature was discharged up to the standard. In this way, a large part of heat is lost; and in the process of urban environment management, the treatment of urban wet sludge is an urgent problem to be solved. Invention content: [0003] The present invention aims at the above problems, and provides a device and a treatment process for treating sludge using waste heat discharged from boiler flue gas. [0004] In order to achieve the above object, the present invention adopts the following technical scheme, which adopts the followin...
