Abstract

The invention discloses a vertical sludge dryer. The vertical sludge dryer comprises a sealing cap, a tower body, a fixed hot tray, a steam main pipe, a draught fan, a driving device, a rotary arm and a heat recovery boiler, and further comprises a cyclone separator, a plasma dust remover and an activated carbon absorber which are connected sequentially. The vertical sludge dryer is characterized in that the driving device is arranged at the bottom of the tower body and connected with a spindle through a coupler; the rotary arm is mounted on the spindle; a half arm of the rotary arm is fan-shaped; symmetric pull rods are arranged on the rotary arm; the fixed hot tray is semicircular, and communicated with the steam main pipe through a pipe; a conical distributor is arranged at the upper part of the tower body. The vertical sludge dryer is provided with the device for efficiently recovering heat energy, processing waste gases and deodorizing with high automation degree, and utilizes the waste heat to indirectly heat, thereby improving the energy utilization rate, further reducing the moisture content of the sludge and effectively avoiding secondary pollution of the waste gases.

Description

technical field [0001] The invention relates to a vertical sludge dryer, which belongs to the technical field of environmental protection sludge treatment. Background technique [0002] With the increasing discharge of urban industrial wastewater and domestic sewage, the urban sewage treatment rate has also increased year by year, and the sludge output of urban sewage treatment plants has also increased sharply. The sewage treatment plant needs to discharge a large amount of excess sludge, and the huge amount of sludge needs to be further processed. If the sludge is not properly treated, it will cause secondary pollution. The treatment and disposal cost of sewage sludge is relatively high. In the total construction cost of the sewage treatment plant, sludge treatment accounts for 20% to 50%. The composition of sewage sludge is very complex. In addition to containing a lot of water, it also contains a lot of useful resources. At present, there are various methods for urban ...
