Benefits of technology
"The present invention provides a process and apparatus for the treatment of domestic waste and sewage by heating the sewage with waste and using high-temperature and high-pressure to generate electricity. The treated waste and sewage can then be separated from each other. The process and apparatus offer a weight and volume-reducing, innocuous and energy-generating treatment for domestic waste and sewage. The apparatus includes a closed incinerator, a turbine generator, and sewage pipes for supplying drive-power / force to the turbine generator. The sewage pipes have a narrow form close to the incinerator and a wider form away from the incinerator to enhance the impact on the turbine. The sewage is then guided under pressure into multi-layer pipes and sucked out through air suction pumps. The residue can be safely used as fertilizer for farms. The apparatus also includes an air suction pump and a gas-reflow-preventing device to prevent gas reflow during the mixing of sewage and exhaust gas."
Problems solved by technology
Since the undermost pipes are directly heated up by the incinerator and the pipes are wide above and narrow below, the sewage thus intensively impacts the turbine of the generator.

Embodiment Construction
[0016] The embodiments of the present invention are illustrated in combination with the figures as follows.
[0017] As shown in FIG. 1, an apparatus for the treatment of domestic waste and sewage in accordance with the present invention comprises a closed incinerator 1, a turbine generator 2 and sewage pipes 3 for supplying drive-power / force to the turbine generator 2. The sewage pipe 3 is positioned above the closed incinerator 1 and heated by the same, so that the sewage in the sewage pipes 3 is put into a high temperature and pressure condition very quickly thereby providing a drive-power / force to the generator 2. Then, the sewage at high temperature and pressure is guided into a neutralization chamber 4 together with the exhaust gas which is generated by the burning in the closed incinerator 1 and sucked out by an air suction pump 5 arranged above the closed incinerator 1. The liquid-mixture is guided under pressure into multi-layer pipes 6 through a pressurizing machine 9. Final...

The present invention provides a process for the treatment of domestic waste and sewage, where the filtered sewage is heated by the burning of waste, and the sewage under high-temperature and high-pressure pushes a turbine generator to generate electricity. Then the solution-mixture of sewage under high temperature and pressure and the exhaust gas generated by the burning of waste, after neutralization with acid and base, undergoes a drying-treatment by sucking out the water steam, and clean water and residue are finally separated from each other. An apparatus for the treatment of domestic waste and sewage is also produced having a closed incinerator, a turbine generator and a sewage pipe for supplying drive-power / force to the turbine generator. In this way, domestic waste and sewage can be treated together, and meanwhile a weight and volume-reducing, innocuous and energy-generating treatment of the domestic waste and sewage is realized.
Description
BACKGROUND OF THE INVENTION [0001] The present invention relates to an environment-friendly process and apparatus, in particular, to a process and apparatus for the treatment of domestic waste and sewage. [0002] Currently, the internationally popular refuse innocuous treatment mainly comprises sanitary landfill, burning and composting, which either requires a big area occupation, or high investment and treatment cost, or complex operation. A set of waste incinerating equipment provided by USA, Japan, Norway or Denmark costs usually about 20-25 million US dollars. It is the high investment and the inconspicuous in-out economic benefit that make many cities overburdened. The current overall treatment cost in China is over 15 billion Yuan per year even if the low-cost sanitary landfill is fully employed. Meanwhile, in many cities sewage is treated in a centralized and very simple way, and is then discharged into a river, which may thus cause a large waste of water resources. SUMMARY OF...
