Embodiment Construction
[0037] figure 1The basic structure of a preferred embodiment of the sludge drying device of the present invention is shown. The sludge drying device includes a drying chamber composed of a transparent glass closed shell 6, which is arranged horizontally in multiple layers. The tray support 3 in the housing, the feed port 1 corresponding to each layer of tray support provided on the lateral right side wall of the housing 6, and the feed port 1 on the opposite side (left side) wall of the housing 6 and the feed port 1 The discharge port 2. The inlet and outlet ports are respectively connected with sealing plates 7 that can seal the inlet and outlet ports. In this embodiment, the sealing plate 7 is rectangular and made of double-layer hollow transparent glass. The sealing plate can move up and down, and is fixed to the corresponding position on the surface of the housing by bolts. Sealing strips 8 are provided on the four sides (such as figure 2 As shown, among them, A shows t...

The invention relates to a sludge drying device and a sludge drying method thereof, wherein, the device comprises a closed transparent glass shell, a plurality of layers of tray stents transversely arranged in a shell, a feed inlet arranged on the transverse side wall of the shell corresponding to each layer of tray stent, a discharge outlet on a side wall corresponding to the feed inlet, a seal plate with transparent glass which can be disassembled and connected with the outer surface of the shell and can respectively seal the feed inlet and the discharge outlet, a material tray which can freely pass through the feed inlet and discharge outlet or is arranged on the tray stent, rectifier fans respectively arranged at the bottom and top of the shell, an air inlet which is arranged at the lower part of one side of the shell, a transparent glass seal-board which is articulated with the top of the air inlet and is matched with the air inlet, a rain insensitive device arranged on the air inlet, an air outlet pipe on the side wall of the shell corresponding to the air inlet, a matched ventilation fan, and a humidity automatic monitoring device which is arranged in the shell and controls the open and close of the ventilation fan.The product discharges the vapor of the sludge to outside to achieve fast drying.
Description
technical field [0001] The invention relates to environmental protection equipment, in particular to a sludge drying device capable of reducing the water content of dehydrated sludge to meet requirements in a relatively short period of time and a sludge drying method using the device. Background technique [0002] National sewage treatment plants discharge more than 5 million tons of wet sludge every year. A large amount of sludge that has not been stabilized and harmlessly treated has become a heavy burden on sewage treatment plants, and at the same time it has caused secondary pollution to the environment. In order to facilitate the transportation, storage and processing of sludge, the sludge after preliminary dehydration must be further dried to reduce the volume of sludge and transportation management costs, and create new opportunities for the next step of reuse (such as fuel, building materials, etc.) condition. Therefore, the dehydration treatment of sludge is very ...
