Abstract
The present invention relates to environment protecting technology, and is especially one kind of microwave sludge treating method. The apparatus consists of microwave treating tunnel, conveying belt, microwave emitter, microwave baffle and other parts. The present invention features the capacity of wall breaking and sterilizing treatment on sludge, high dewatering efficiency and harmless treatment effect, low power consumption, fast speed and environment friendship. The present invention is suitable for treatment of different kinds of sludge.
Description
Technical field
The present invention relates to environmental technology field, especially relate to a kind of sludge microwave handling method.
Background technology
The sludge yield of municipal sewage plant is huge, though have the value of recycling, also has objectionable impurities simultaneously, and stacking or landfill have a big risk, and handle and the disposal costs height.Thereby how safety, economical, scientifically utilize mud to become the research topic that various countries, the world today extremely pay close attention to.
Cause the high one of the main reasons of sludge treatment and disposal costs, be that moisture percentage in sewage sludge is very high, and be rich in organic substance, particle is thin, is cotton-shaped colloidal structure, have high-hydrophilic, but dewatering is poor, so the mummification operation easier of mud is big, and the cost height.
Water in the mud can be divided into surface adsorption water, capillary combination water, interstitial water, cellular water according to form.Interstitial water is meant the cingens free water content of mud granule, is easy to separate, and can utilize action of gravity that it is separated, and is that gravity concentrates object; The capillary combination water is meant the moisture in the mud granule crack, is difficult to separate, and needs higher mechanicals efforts and energy, could remove as vacuum filtration, filtering under pressure or centrifugation, and be the mechanical dehydration object; Surface adsorption water is meant the moisture that is adsorbed in mud granule under capillary effect, because of mud granule very little of being cotton-shaped colloid, specific surface area is very big mutually with its volume, surface tension is very strong, and these colloids have electric charge, repulsion mutually, hinder agglomeration of particles, grow up, keep stable status, and be difficult to remove, the charge neutralization of colloidal solid could be removed by pre-treatment (modified or nurse one's health, add flocculation agent etc.); Cellular water mainly is meant the intravital moisture of microorganism cells in the biological sludge, is subjected to the most difficult removal of protection of cell walls.Remove cellular water, must destroy cell walls (film), cellular water is oozed out.
At present the utilisation technology of mud broken wall mainly contains aerobic sigestion, anaerobic digestion, compost, heat and freezing etc., does not see as yet and delivers about utilizing microwave technology to carry out the patent documentation of device of mud broken wall treatment and correlation technique document.
Summary of the invention
The purpose of this invention is to provide a kind of sludge microwave handling method, this method can be carried out broken wall and sterilising treatment to mud continuously, improves the processed efficient and the sewage sludge harmlessness treatment effect of (follow-up) mud.
The object of the present invention is achieved like this:
1. sludge microwave handling method, mainly comprise hopper, microwave treatment tunnel and discharge bucket, it is characterized in that the microwave treatment tunnel is a rectangle or a circular enclosed appts, in be provided with travelling belt, front upper is provided with hopper, and front part sides is provided with viewing window; The middle part is provided with the microwave emitter of a plurality of arranged in arrays and blast inlet, air outlet; The afterbody below is provided with discharge bucket.Above-mentioned hopper and discharge bucket are made up of chute and feeder.Feeder inside be arranged in parallel and has four or four rotating shafts with blade, and two are provided with arc microwave plate washer, and rotating shaft is by electric motor driving.The above-mentioned arc microwave plate washer and the blade of rotating shaft form a barrier all the time, can prevent effectively that microwave from leaking.
During the work of this sludge microwave handling method, mud enters hopper, drive through the rotating shaft of the band blade of feeder and to be laid on the travelling belt equably, then accept the microwave broken wall and the sterilization virus killing of microwave emitter emission through middle part, microwave treatment tunnel, then from the travelling belt discharge bucket that drops, drive this method of sending through the rotating shaft of the band blade of feeder.
The present invention has following characteristics:
(1) dewatered sludge to water ratio≤80% carries out microwave treatment, only need be heated to just generation boiling of moisture in 70～80 ℃ of mud, reaches the broken wall purpose, and is not only energy-conservation, quick, and more environmental protection;
(2) can handle suitability for industrialized production degree height continuously;
(3) microwave emitter only is arranged on middle part, microwave treatment tunnel, the front and rear in microwave treatment tunnel all becomes transition section, can reduce the microwave radiation of distributor and discharger position greatly, add the anti-microwave leakage effect of microwave plate washer, the microwave anti-leak result of this device is more remarkable.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is a feeder sectional view of the present invention
1 hopper; 2 microwave treatment tunnels; 3 discharge buckets; 4 travelling belts; 5 microwave emitters; 6 blast inlets; 7 air outlets; 8 viewing windows; 9 chutes; 10 feeders; 11 microwave plate washers; 12 rotating shafts; 13 blades.
The present invention not only can process the continuous broken wall of mud and sterilization virus killing, also can the mud of low-water-content be advanced The row continuous drying is processed.
Claims (6)
1. sludge microwave handling method, mainly comprise hopper, microwave treatment tunnel and discharge bucket, it is characterized in that being provided with travelling belt in the microwave treatment tunnel that front upper is provided with hopper, the middle part is provided with a plurality of microwave emitters and blast inlet, air outlet, and the afterbody below is provided with discharge bucket.
