Description
Technical Field
The utility model relates to a sludge treatment technical field, concretely relates to utilize steam mummification mud system.
Background
By 2013, 3500 seats of sewage treatment plants in China exist, the sewage treatment capacity reaches 1.45 billion cubic meters per day, 3000-year sludge is 3500 ten thousand tons (the water content is about 80 percent), and the sewage treatment scale is close to that of the United states.
From the viewpoint of resource utilization, the treatment and disposal techniques need to be considered from the properties and characteristics of sludge, and more than 60% of sludge is protein and contains organic matter. In the sludge treatment process, the international current standard is 'four-transformation', namely stabilization, reduction, harmlessness and recycling, and the current situation in China is that 80% -90% of sewage and sludge are only simply concentrated and dehydrated, the water content of the dehydrated sludge is still high, and the sludge is incinerated by adopting the traditional incineration mode, so that the energy consumption is huge.
Disclosure of Invention
The utility model provides an utilize steam mummification mud system.
The technical scheme of the utility model:
a system for drying sludge by using steam comprises a sludge dryer; the dried sludge system also comprises a condenser and a preheating heat exchanger; a plurality of steam heaters are fixedly arranged in the sludge drying machine, and all the steam heaters are respectively connected with a steam pipeline and a steam condensation pipeline and are connected with a preheating heat exchanger through the steam condensation pipeline; the sludge drier is connected with the condenser through an exhaust pipeline, the condenser is connected with the preheating heat exchanger through a circulating pipeline, and the preheating heat exchanger is connected with the sludge drier through an air inlet pipeline to form a hot air circulating loop; an air inlet fan is arranged on the air inlet pipeline, and an air exhaust fan is arranged on the air exhaust pipeline; preferably, the sludge drying device is a belt type sludge drying machine,
when the system is used, of course, the air inlet pipeline is communicated with air, fresh control is sent into sludge drying through the air inlet pipeline by the air inlet fan, the fresh control is heated by the steam heater to form hot air, the hot air is contacted with sludge, after the sludge is dried, the fresh control is sent into the condenser through the exhaust pipeline by the air exhaust pipeline, after condensation and dehydration, the fresh control is sent into the preheating heat exchanger through the circulating pipeline for preheating, after preheating, the fresh control is sent into the sludge drying machine through the air inlet fan through the air inlet pipeline, and the circulation is carried out. Simultaneously in this application steam is as steam heater's heat source, heats fresh air, and steam passes through steam heater simultaneously and forms the steam condensate water of high temperature, still possesses higher temperature for the hot-blast temperature after the condensation, like this, preheats the hot-blast after condensing with its heat source as preheating heat exchanger for during it gets into the sludge drying machine, can be more quick reach the demand temperature through steam heater, make full use of steam heat reduces the energy consumption.
The air volume of the air inlet fan is smaller than that of the air exhaust fan, the air inlet fan and the air exhaust fan work simultaneously, and micro negative pressure of-0.5 mbar is formed in the drying machine; the odor can be effectively prevented from overflowing.
The sludge drying machine is internally provided with a plurality of temperature probes, the steam pipeline is provided with an electromagnetic control valve, the temperature probes are in control connection with the electromagnetic control valve, and the electromagnetic control valve is controlled to open or close the steam pipeline.
And a steam trap is arranged on the steam condensation pipeline.
The circulating pipeline is also connected with an exhaust pipeline.
The utility model has the advantages of, reasonable in design, simple structure utilizes steam as the heat source, heats the air that gets into in the sludge drying machine and forms hot-blastly for the sludge drying utilizes the high temperature comdenstion water that steam formed through steam heater to preheat the hot-blast after the condensation simultaneously, recycles in the sludge drying machine is sent into to the recirculation wind form.
