Embodiment Construction

[0016] Such as figure 1 A vertical combined sludge drying device is shown, its core components are mainly composed of upper, middle and lower conveyor belts arranged in three layers, vibrating lower plates and vibrator screens arranged between the middle and lower layers. The conveyor belt is made of aluminum alloy crawler with large gap.

[0017] This vertical combined sludge drying device has a drying room. Above the steel structure beam on the top of the drying room is an interlayer arched roof of the drying room. There is a top hot steam recovery in the middle of the interlayer arched roof of the drying room. There is a water vapor return groove at the lower edge of the interlayer arched roof in the drying room, and there is a main hot air duct in the wall of the drying room. The entrance of the main hot air duct is outside the wall of the drying room. Inside the partition wall, there is also a main hot air duct on the ground of the drying room. The inlet of the main hot ...

Abstract

A vertical combined sludge drying device. Above the steel structure beam on the top of the drying room is an interlayer arched roof. There is a top hot steam recovery port in the middle of the roof. There is a water vapor return groove on the lower edge of the roof. There are hot air main pipes inside and on the ground, and the outlets of multiple hot air main pipes are in the wall of the drying room and on the ground. There is a sludge conveying inlet above the wall of the drying room. There are multiple layers of metal mesh conveyor belts arranged. Below the discharge side of the bottom metal mesh conveyor belt is a metal vibrating lower slide. Below the discharge edge of the lower slide is a metal oscillator screen. The discharge side of the net conveyor belt is facing the dry mud granulation outlet. The sludge drying device makes full use of the space, the three-dimensional combined structure is reasonable, and the comprehensive performance is strong. It has fast drying speed, high evaporation intensity and good consistency of material drying. Easy to install, operate and maintain. Safe and efficient, energy saving and environmental protection.

Description

technical field [0001] The invention belongs to environmental protection innovation technology---equipment for reuse of sludge and garbage resources, in particular to a vertical combined sludge drying device. technical background [0002] With the development of industry and cities and the improvement of sewage treatment rate, the output of municipal sludge is increasing. Sludge is a potential resource with great utilization value. In order to make full use of this resource, the vertical combined sludge drying device is an indispensable and important treatment link in the disposal of sludge and garbage. Drying device usually refers to the process of using heat energy to vaporize the moisture in the material and remove the generated steam. make it possible to: [0003] Reduction and drying can greatly reduce the volume of sludge, which is convenient for transportation and disposal. [0004] Stabilization, after the sludge has been sterilized at high temperature, the dried ...
