Description
Technical field
This utility model belongs to field of sludge treatment, particularly relates to a kind of fluid bed sludge drying device.
Background technology
Along with the development of urbanization, municipal sewage is on the increase, and mud is as the side-product after sewage disposal, how to process and has become a great problem that society faces. Fluid bed is as drying equipment. General with hot-air or steam etc. for mummification medium, mud is carried out mummification, after mud enters fluid bed, mummification medium is entered by fluidized-bed bottom, mud granule in fluidized-bed reactor moves upward with air draught, and absorb heat, after mummification, sludge water content precipitates out and produces steam, taken to the mud granule on fluidized-bed reactor top under gravity by air-flow, surrounding is avoided to fall back to fluidized-bed reactor bottom along fluidized-bed reactor, proceeding mummification, after mummification completes, mud granule is discharged from fluid bed overfall. But in prior art, Treatment of Sludge power consumption is big, and drying time is long, and mummification efficiency is low.
Utility model content
The purpose of this utility model is to overcome prior art to there is the power consumption of fluid bed Treatment of Sludge greatly, the defect of drying time length, it is provided that a kind of fluid bed sludge drying device.
This utility model solves its technical problem and be the technical scheme is that a kind of fluid bed sludge drying device, including solar heater, fluid bed and compressor; Described solar heater includes reflecting plate, communicating pipe and some thermal-collecting tubes, and some described thermal-collecting tubes were connected by described communicating pipe, and described reflecting plate is arranged on the bottom of described thermal-collecting tube; Being provided with steam (vapor) outlet on described thermal-collecting tube, described steam (vapor) outlet connects the bottom of described fluid bed; Described fluidized-bed bottom is provided with overfall, and described fluid bed top is provided with moisture outlet, and described compressor is connected with described moisture outlet.
As preferably, for effectively utilizing the heat of the steam that mud precipitates out in vulcanization bed, described fluid bed top is additionally provided with the conveying worm for carrying mud, being provided with chuck outside described conveying worm, described chuck one end is provided with the air inlet being connected with described moisture outlet and the gas outlet connected with described compressor. Utilize the steam in fluid bed that the mud in spiral conveying mechanism is preheated, it is possible to increase the utilization rate of heat, improve mummification effect.
Further, during for avoiding not having sunlight or sunlight deficiency, solar heater is not provided that and is additionally provided with heater between described solar heater and described fluid bed by enough steam.
As preferably, described reflecting plate upper surface is provided with some cambered surfaces, described cambered surface and described thermal-collecting tube one_to_one corresponding, and is enclosed in outside described thermal-collecting tube. Sunlight is when being radiated in cambered surface, and cambered surface can arrange on thermal-collecting tube by counter for sunlight so that thermal-collecting tube obtains more energy so that its internal heating-up temperature is higher.
Beneficial effect: utilize solar energy heating to produce steam in the application and mud in fluid bed is carried out mummification, utilize compressor that the gas discharging fluid bed moisture outlet is carried out freeze drying simultaneously, thus improving temperature difference and the moist gradient of fluidized bed steam entrance and moisture outlet, accelerate moisture diffusion speed in mud, improve flow rates, thus improving sludge drying efficiency, reduce drying time.
