Embodiment Construction

[0011] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0012] like figure 1 As shown, the sewage sludge combined treatment system of the present invention includes a feeding hopper 1, a heat exchange device 2, a feeder 3, a granulator 4, a combustion boiler 5, and first to fourth air pipes 6, 7, 8, 9. The reaction tower 10, the water pump 11, the sewage pipe 12 and the gas outlet 13, etc. figure 1 middle:

[0013] .

[0014] The feeding hopper 1 is connected with the heat exchange device 2, and the feeding hopper 1 is equipped with an automatic valve. When there is no feeding, the valve is automatically closed to avoid the escape of flue gas. The heat exchange device 2 is connected with the feeder 3, the feeder 3 is connected with the granulator 4, the granulator 4 is connected with the incineration boiler 5, and the top of the incineration boiler 5 is communicated with the first air conduit 6 and the se...

Abstract

The invention relates to a sewage and sludge joint treatment system, which comprises a loading hopper, a heat exchange device, a feeder, a granulator, a fume guide pipe, an incineration boiler and a reaction tower, wherein the loading hopper is connected to the heat exchange device; the heat exchange device is communicated with the granulator through the feeder; the granulator is connected with the incineration boiler; the top of the incineration boiler is respectively communicated with the heat exchange device and the feeder through a first gas guide pipe and a second gas guide pipe; the heat exchange device and the feeder are respectively converged through a third gas guide pipe and a fourth gas guide pipe and then communicated with the bottom of the reaction tower; and the top of the reaction tower is communicated with a sewage pipe. By adoption of the sewage and sludge joint treatment system, the cost of sewage treatment can be reduced, sludge to be incinerated is pre-heated by using high-temperature fume which is generated through sludge incineration, the sludge to be incinerated can be incinerated, and the cost of a sludge drying process is reduced.

Description

technical field [0001] The invention relates to a sewage sludge treatment system, in particular to a sludge treatment system capable of saving energy. Background technique [0002] With the development of industry, the discharge of various wastes has greatly increased, and industrial wastewater and urban sewage have caused more and more pressure on the environment. The urban sewage treatment plant is an important means to solve water pollution, but the sludge produced by the treatment plant has also become a major public hazard to the urban environment. The sludge has a huge output and complex composition. In addition to containing a lot of water and organic matter, it also contains microorganisms, parasite eggs, and possibly heavy metals and other harmful substances. Improper handling will seriously endanger people's health. The reduction, harmlessness and recycling of sludge is one of the important issues in environmental protection around the world. Sludge treatment mai...
