Abstract

The invention provides a domestic sludge and pulverized coal drying and forming device which comprises a sludge double-spiral charging device, a pulverized coal spiral charging metering device, a vacuum pump interface, a steam interface, a rotary joint, a transmission system, a single-spiral discharging device, a sludge outlet forming control device and a dryer main body device. The device provided by the invention has the advantages that the transmission speed can be changed according to the treatment capacity; the ratio of sludge to pulverized coal can be controlled by adjusting the rotationspeed of the sludge double-spiral charging device and the rotation speed of the pulverized coal spiral charging device; the particle size of sludge formed particles can be controlled by end plates with different hole sizes, and the length of the sludge formed particles can be controlled by the rotation speed of a revolving scraper; and the shapes and sizes of dried products can be controlled, thecharging difficulty in an incineration process can be reduced, the fuel required for sludge incineration treatment is less, and the sludge can be incinerated more thoroughly.

Description

technical field [0001] The invention relates to the technical field of domestic sludge incineration pretreatment, in particular to a domestic sludge co-coal drying forming device. Background technique [0002] With the growth of population and human demand for water, more and more complex domestic sewage is produced, and the components of sludge produced after sewage treatment by biochemical methods tend to be diversified. Harmful ingredients such as parasites, germs, and odors contained in it will seriously affect the living environment of human beings. Therefore, the development of sludge disposal and utilization technology and equipment has become an important task in the environmental field. Incineration treatment is the best way to completely solve the sludge, but the incineration effect is not good due to the high moisture content (about 70%) of the sludge, so sludge drying is the key to solving the problem. The more thoroughly the sludge is dried, the less fuel is r...
