Description
Technical Field
The utility model relates to an excess sludge treatment field, concretely relates to intensive complete set excess sludge drying equipment of three-dimensional many planes.
Background
Along with the acceleration of the urbanization process in China, the urban sewage treatment rate is improved year by year, the sludge yield is also increased sharply, and the residual sludge yield is more than 4000 ten thousand tons at present in terms of 80 percent of water content. According to incomplete statistics, only a small part of sludge of the urban sewage treatment plant in China is subjected to sanitary landfill, land utilization, incineration and the like, and most of the sludge is not subjected to standardized treatment, so that waste and secondary pollution are caused to land resources, and the environmental safety and public health are directly threatened. In the existing disposal mode of the excess sludge, land landfill accounts for 63.0 percent, sludge aerobic fermentation accounts for 13.5 percent, sludge natural drying comprehensive utilization accounts for 5.4 percent, sludge incineration accounts for 1.8 percent, and sludge open-air stacking and outward transportation respectively accounts for 1.8 percent and 14.4 percent. In any treatment method, the dewatering reduction of excess sludge is an important part of the whole treatment process, taking 100 tons of sludge with 98% water content as an example, the sludge is initially dewatered to 80% water content, the amount of the sludge is changed to 10 tons, the equipment for realizing the initial dewatering is equipment such as a belt filter press, a plate-and-frame filter press, a screw-stacking dewaterer and the like, the equipment can only fulfill the aim of initial dewatering, if the water content is further reduced from 80% to 40% to realize deep dewatering, the amount of the sludge is changed to 3.3 tons, the reduction is very obvious, the amount and the cost of subsequent treatment of the sludge can be greatly reduced, and the treatment such as landfill, incineration and the like requires the water content to be at a lower level.
At present, equipment for realizing deep dehydration comprises heat drying equipment, cyclone drying equipment and the like. The sludge heat drying equipment is concerned about due to stable operation and high efficiency, and is more and more widely applied.
The residual sludge treatment and disposal technical route is more, and the patent only explains the technical route of sludge heat drying. Sludge heat drying equipment is a means for dewatering and reducing sludge, and is generally used in combination with a stack screw dehydrator, a belt filter press, and the like. The water content of the residual sludge in the concentration tank is about 98 percent, the water content of the sludge is reduced to about 80 percent by adopting a screw-stacking dehydrator generally, then the sludge enters a sludge heat drying device for further dehydration and drying through a screw pump, and the final water content can be controlled according to different requirements in various places. The main components of the whole set of dehydration and drying equipment comprise a conventional sludge feeding pump, a screw-stacking dehydrator, a screw pump, heat drying equipment, a conveying belt, a dry sludge bin and an outward transport truck. In the primary dewatering section of the screw stacking machine, because the water content of the sludge is very high and the sludge has the same fluidity as water, the sludge entering the screw stacking dewatering machine is conveyed by a conventional water pump, and the sludge discharged with the water content of 80 percent is mainly transferred and conveyed by a screw pump; after the sludge is dried, the water content is further reduced to be solid, and the solid enters a dry sludge bin by mainly adopting modes of screw conveying, belt conveying and the like to wait for further treatment by external transportation.
Currently, in practical engineering and application processes, the several main components are usually arranged in one or two planarisation. Aiming at the situation of two planes, a conventional sludge feeding pump, a screw-stacking dewaterer, a screw pump and a heat drying device are arranged on one low-level plane, a dried sludge bin is arranged on the other high-level plane, the dried sludge is conveyed to the high-level bin through a vertical conveying or partition plate, and the sludge in the high-level bin is directly dropped to an outward-conveying truck of the low-level plane through control for loading and outward conveying (as shown in figure 1). The condition of arranging for a plane is that all units arrange at same plane, and the mud of mummification is transported to the drier storehouse through screw feed or belt, and the mud of drier storehouse is handled through the loading outward transportation of forklift truck.
In both the one-plane and two-plane arrangements, since the sludge must be transported between different levels of equipment, various transport devices such as screw transport, baffle transport, etc. are inevitably required, and the transport of solids is relatively high in terms of the cost of the equipment, the operating cost, the failure rate of the equipment, etc. compared to the transport of liquids. The transmission equipment is often maintained or even repaired, and once the transmission equipment has a problem, the normal operation of the whole process is directly influenced. Furthermore, all these plants do not form a standardized plant by a rational arrangement.
