Abstract
The utility model relates to a low-temperature phase change mud dryer, adopting low temperature indirect heating, phase change heat exchange and spiral conveying technology. The utility model is characterized in that an outer cylinder wall interlayer is sleeved and sealed on a spiral drier for ensuring the mud drying together with a heating tube of an inner spiral shaft. The mud is dried in low temperature by the heat generated by heat transfer of heat medium and phase change of steam liquefication, therefore the moisture content is greatly reduced, the volume of the mud is greatly reduced and the dried mud can be used as energy source. Simultaneously, the steam in the niff of the mud steam is removed after condensation and then the niff enters into a boiler for burning or into other devices for treatment in order to protect the environment.
Description
Technical field: the utility model relates to a kind of sludge at low temperature phase transformation drying installation, particularly a kind of practical sludge at low temperature phase transformation drying installation.
Background technology: a B-grade sewage treatment plant, the sludge quantity of generation accounts for always the 0.3%-0.5% of the amount of disposing of sewage (volume), as carries out advanced treatment, and sludge quantity also may increase 0.5-1.0 doubly.These materials are treatment and disposal in time, could guarantee the normal operation and the treatment effect of sewage work, the protection environment.Though the treatment and disposal to mud proposes and has adopted some feasible methods at present, but the energy that what use is made of is minimum, reach to subtract and hold and recycle thereby reduce in the mud percentage composition of moisture again in a large number, and the problem such as foul smell discharging of avoiding in the drying sludge process all needs to solve.
Summary of the invention: the purpose of this utility model provides a kind of high heat transfer coefficient of phase transition process that makes full use of mud is carried out drying treatment, and guarantees not have foul smell to discharge, and is a kind of sludge at low temperature phase transformation drying installation of clean and effective.
For achieving the above object, the technical solution of the utility model is: a kind of sludge at low temperature phase transformation drying installation, its characteristic is to have adopted simultaneously low temperature indirect heating, phase-change heat-exchange and helical feed technology.It comprises mud stroke passage, mud steam stroke passage, heating medium stroke passage, mud stroke passage is provided with import and export, be provided with spiral dryer in it, the screw shaft of spiral dryer is a heating medium stroke passage, the screw shaft end links to each other with pipe connecting, pipe connecting moves towards the pipe back by " U " type and feeds the barrel interlayer that is nested with on mud stroke passage, the other end at the barrel interlayer is provided with outlet, mud stroke passage top is a tongue shape collection chamber, collection chamber links to each other with steam duct, feeding is provided with the condenser of dividing plate, and condenser is provided with pneumatic outlet.
This device can be secondary, be equipped with spiral dryer in the two-stage mud stroke passage, two interchannels link to each other by the mud tremie pipe, the secondary passage lower end is provided with outlet, one-level heating medium passage links to each other with the screw shaft sealing of deuterostrophies moisture eliminator by pipe connecting, connect one-level barrel interlayer, secondary barrel interlayer by pipe connecting again, and be provided with outlet at its end; The mud steam stroke passage of two-stage all is connected on the condenser by steam duct.
The utility model is owing to adopt said structure, the mud that makes water content higher (70%-80%) is at the spiral dryer inner drying, heating by water vapour in the screw shaft or flue gas, make the mud evaporation drying, the water vapour that evaporates simultaneously liquefies after the condenser effect, because mud side heat exchange temperature is lower in the drying process, the foul smell that mud so decomposition are emitted seldom.Sludge moisture content after drying is about 20%-40%, belongs to dewatered sludge basically, is equivalent to low grade coal, can be used as energy utilization.Expellant gas in the drying sludge process is collected in the condensation water tank through prolong effect water vapour, and remaining foul smell is sent in the boiler and handles.
Description of drawings: Fig. 1 is the structural representation of this device.
Fig. 2 is the A-A sectional view of Fig. 1.
Embodiment: embodiment of the present utility model is described further below in conjunction with accompanying drawing:
1 one kinds of sludge at low temperature phase transformations of embodiment drying installation, it comprises mud stroke passage, mud steam stroke passage, heating medium stroke passage, mud stroke passage is provided with import and export, be provided with spiral dryer 4 in it, the screw shaft 5 of spiral dryer is a heating medium stroke passage, the screw shaft end links to each other with pipe connecting 9, pipe connecting moves towards the pipe back by " U " type and feeds the barrel interlayer 6 that is nested with on mud stroke passage, and be provided with outlet endways, on mud stroke passage top is tongue shape collection chamber 3, collection chamber links to each other with steam duct 10, feeding is provided with the prolong 12 of dividing plate 14, link to each other with condensation water tank 15 by prolong, prolong is provided with pneumatic outlet 17.
Sludge at low temperature phase transformation drying installation has adopted low temperature indirect heating, phase-change heat-exchange and helical feed technology simultaneously.This technology comprises mud stroke, mud steam stroke, three strokes compositions of heating medium stroke.Mud enters spiral dryer 4 by the inlet 2 of spiral dryer 4, carries out evaporation drying, and it is further dry to enter next stage spiral dryer 11 through mud tremie pipe 7 again, gets rid of exsiccant mud by the outlet 19 of spiral dryer 11 at last; Mud steam by the top collection chamber 3 of spiral dryer 4 and 11 and 21 and mud steam duct 10 enter condenser 13, prolong 12 condensations through being furnished with dividing plate 14, behind the water vapor condensation in the mud steam by condensation-water drain 16, enter condensation water tank 15, other gas in the mud steam stroke is discharged through dividing plate 14, pneumatic outlet 17; The screw shaft 5 that heating medium enters spiral dryer 4 by inlet 1 enters the barrel interlayer 6 of spiral dryer 4 through pipe connecting 9,20, enters the barrel interlayer 22 of next stage spiral dryer 11 again through pipe connecting 8, is flowed out by outlet 18 at last.
Water ratio be 70～80% mud after this device drying, sludge moisture content can drop to 20%-40%, can be used as the energy and uses, and is equivalent to low grade coal.The barrel interlayer that is sleeved on the spiral dryer outside has guaranteed the gas fluidity of mud steam and then discharge smoothly, and drying sludge is better carried out, and can add the forward spin flow plate in case of necessity, so that play the better heating insulation effect.
