Problems solved by technology

For example, the French patent No.FR0311957 we know uses the thermal oxidation exchange technology of steel balls and sludge. The temperature of thermal oxidation is between 350°C and 395°C, which does not reach the high temperature of 850°C required for full decomposition, nor can it Meet the requirements of the exchange treatment temperature between 145 and 165°C when one kilogram of sludge is mixed with thirty kilograms of steel balls
This also cannot meet the temperature required to obtain the full combustion of flammable dry substances required for hot air jet combustion

Embodiment Construction

[0039] The technological process and equipment of the present invention can carry out thermal oxidation decomposition treatment of organic sludge on site, and the main processes are dehydration, thermal oxidation reaction, and dust purification.

[0040] Sludge from a sewage treatment plant generally has a water content of about 85%, a dry matter content of about 15%, and organic volatile matter and dry-based volatile matter in the dry matter account for about 76%. The organic matter has the following components: Carbon C: 49 %, Hydrogen H: 7%.

[0041] Process flow method feature of the present invention, with reference to Fig. 1, Fig. 2:

[0042] The 0.5%-2% sludge slurry passes through the centrifugal separator 1, and the water and sludge can be separated from the water and 15%-15% sludge through centrifugal action, and each kilogram of sludge is combined with the metal ball drying system (mixer In )2, every 100 kg of metal balls with a temperature of 100°C-180°C are mixed...

Abstract

The present invention relates to a thermal oxidative treatment method and system for organic sludge, wherein the organic sludge and a thermal metal ball are mixed and transported to an oxidative chamber to burn, where the temperature reaches 850 to 1000 DEG C required by sludge complete oxidation decomposition, the reactive result is to generate flue gas and dust that contain COV, polychlorinated dibenzo-p-dioxins, and polychlorinated dibenzo-furans which is absorbed from a dioxin collecting-purifying tank and is dissolved in an oilness dissolvant, 60% of the fuel gas and dust heat can be used in a next circulation reheating reaction of the steel ball and the sludge, the temperature of the gas after purifying processing is 22 DEG C, thus it is able to reduce greenhouse gases discharge and energy consumption.

Description

technical field [0001] The invention relates to an on-site incineration and decomposition treatment technology, process and equipment system of sludge (including organic sludge produced by a sewage treatment plant), in particular to a thermal oxidation treatment process method and system of organic mud. Background technique [0002] As we all know, the practical problem of difficult treatment of a large amount of sludge produced by sewage treatment is very common in the world. There are many discussions on this aspect, so I will not list them here. Just enter "pollution" on the Internet The word "mud" yields a wealth of information about its impact on the environment and on health. [0003] All countries in the world have carried out a lot of work on this problem: Switzerland adopts the method of collecting sludge for centralized treatment, and applies special equipment to solve the problem of sludge incineration treatment, but the process of centralized collection still req...
