Embodiment Construction

[0020] The implementation of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0021] The whole integrated solar sludge drying system mainly includes: multi-functional solar room 14, thermal oil tank 1, solar collector 3, fan 4, solar air collector 5, sludge feeder 7, shaftless screw dryer 8 and mud pool 11.

[0022] see figure 1 , the solar heat collector 3 and the solar air heat collector 5 are arranged in a position with sufficient light sources to collect solar energy, the heat generated by the solar energy heats the air and heat transfer oil respectively, and the hot air and hot oil are transported by the oil pump 2 and the fan 4 Heat it to the shaftless screw dryer 8 arranged in a triangular three-dimensional arrangement; after preheating for a certain period of time, the sludge feeder 7 runs to pour the mechanically dehydrated sludge into the shaftless screw dryer 8, and adjust the hot air The air volume and the f...

Abstract

The invention relates to the technical field of drying sludge, and particularly relates to an integrated solar sludge drying system functioning by combining a solar thermal collector with a solar house. The drying system comprises a multifunctional solar house, a heat-conducting oil tank, a solar thermal collector, a fan, a solar air collector, a sludge feeder, a shaftless spiral dryer and a sludge storage pool. The floor area of the integrated solar sludge drying system is further reduced compared with a solar sludge drying device with the same sludge treatment capacity, and the sludge drying time of the integrated solar sludge drying system is also shortened compared with the traditional sludge drying by utilizing only the solar house; the system is capable of realizing short-period low-power consumption production of sludge drying, and is easy to implement; and the system has obvious social benefit and circulating economic benefit, thus being capable of being widely applied to the sludge drying treatment of sewage treatment plants.

Description

technical field [0001] The invention relates to the technical field of sludge drying, in particular to an integrated solar sludge drying system utilizing the joint action of a solar heat collector and a solar house. Background technique [0002] With the continuous development of environmental protection, a large number of new sewage treatment plants have been built all over the country, but the sewage treatment plants will produce a large amount of by-products - sludge, if not handled properly, it will cause secondary environmental pollution; according to statistics, by the end of 2010, my country's required The total amount of sludge produced will reach about 30 million tons, and the problem of harmless and resourceful treatment of sludge is becoming more and more prominent. [0003] The moisture content of dehydrated sludge in sewage treatment plants is still as high as 75%~80%, which is huge, and there is no unified model for sludge disposal in various places. Most citi...
