Abstract
The invention belongs to the technical field of sludge dehydration and relates to a novel solar energy sludge drying device and method. The device adopts a structure that a high temperature water tank is connected with an evacuated collector tube, the evacuated collector tube is connected with a water inflow tank, a heating coil is arranged inside the water inflow tank, the high temperature water tank is connected with a circulating pump through a pipeline, and the circulating pump is connected with a screw conveyor. According to the invention, reproduceable clean energy, solar energy, is adopted as main energy, a lot of energy is saved, a solar collector has a simple structure, is convenient to mount and is simple to operate, after sludge drying, the water content can reach about 20 to 30 percent, a small quantity of energy charge is expensed, and after drying, the sludge can be used circularly as raw material of a novel energy.
Description
Technical field
The invention belongs to the sludge dewatering technical field, be specifically related to a kind of new type solar energy sludge drying device and method that is applied to industries such as municipal administration, chemical industry, pharmacy, printing and dyeing, papermaking.
Background technology
Moisture percentage in sewage sludge behind the deep dehydration is generally 50-60%, and mostly drying technique in the market is the steam raising dehydration, and energy-output ratio is very big; Also have some sun power sludge drying techniques, need to build huge transparent drying room, floor space is very big and thermal losses is also bigger, operates, safeguards complicated.
Summary of the invention
Purpose of the present invention is exactly the defective at existing sludge drying technique, improves sludge drying efficient, utilizes reproducible clean energy, with further minimizing sludge volume, reduces secondary pollution, saves the energy.
A kind of sun power sludge drying device, its structure is as follows: high-temperature water tank 1 links to each other with vacuum heat collection pipe 2, and vacuum heat collection pipe 2 links to each other with inlet chest 3, is provided with heating coil 5 in the inlet chest 3, high-temperature water tank 1 links to each other with recycle pump 6 by pipeline, and recycle pump 6 links to each other with worm conveyor 4.
Be provided with chuck 7 between the shell of worm conveyor 4 and the screw shaft.
High-temperature water tank 1, vacuum heat collection pipe 2, inlet chest 3 and heating coil 5 are formed solar energy collector, and solar energy collector is two-stage or plural serial stage, is limited to ten grades of series connection on the plural serial stage.
Adopt above-mentioned sun power sludge drying device, mud behind the deep dehydration discharged from deep dehydration equipment enter worm conveyor 4, the high-temperature-hot-water that has absorbed sun power under the conveying of recycle pump 6 in chuck 7 internal recycle heat releases, mud in the screw shaft is carried out drying and dewatering, and a part of tail gas that water vapour and mud discharge enters tail gas collection system and handles.
Beneficial effect of the present invention: it is main energy sources that the present invention adopts reproducible clean energy sun power, has saved a large amount of energy, reduces the running cost of sludge drying.Solar energy collector can form the modular combination operation, and further stabilizing equipment is stable.Solar energy collector is simple in structure, easy for installation, and is simple to operate.The about 20-30% of water ratio only consumes a spot of electricity charge behind the sludge drying.Mud after the mummification can be used as the raw material recycle of novel energy.
