Embodiment Construction

[0014] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0015] Such as figure 1 As shown, the present invention utilizes Fresnel type solar energy to carry out the device of combustible waste low-oxygen pyrolysis treatment, comprising:

[0016] The reflector 2 fixed on the ground by a bracket can realize uniaxial tracking of the sun, and the paraboloid supported by the ground bracket is fixed on the ground by a bracket to realize the function of tracking the sun on a single axis. The sunlight is concentrated and focused on the lower half of the solar vacuum pyrolysis tube 3 arranged in the air.

[0017] The solar vacuum pyrolysis tube 3, the solar vacuum pyrolysis tube 3 is arranged on the focal line of the reflector whose paraboloid is fixed on the ground by a bracket to realize uniaxial tracking of the sun, and receives the focused solar radiation from the reflector. Provide heat for low-oxygen ...

Abstract

The invention provides a device for low oxygen pyrolysis treatment of combustible rubbish by using Fresnel type solar energy. The device for low oxygen pyrolysis treatment of combustible rubbish by using Fresnel type solar energy heats and distills organic matters by using the thermal instability of the organic matters in rubbish under the anaerobic condition or oxygen deficient condition so as tocause the splitting decomposition of the organic matters; various new gases, liquid and solids are formed after condensation; and fuel oil and combustible gases are extracted from the various new gases, liquid and solids. A reflector (2) which is fixed on the ground by a support and can realize single-axis sun tracking is used for reflecting part of sunlight of sun (1) to a solar energy vacuum pyrolysis pipe (3); heat is fed into rubbish in the solar energy vacuum pyrolysis pipe (3) by a screw conveyer (4), so that the low oxygen high-temperature pyrolysis of the rubbish is realized; rubbishproducts are fed into a pyrolysis product separator (6) along a pipeline (5) for gas-solid separation; pyrolysis gas products are led out by a gas leading-out pipeline (7); and pyrolysis solid products are led out by a solid leading-out pipeline (8).

Description

technical field [0001] The invention relates to a low-oxygen pyrolysis device for combustible garbage, in particular to utilizing Fresnel solar energy to provide reaction heat required for pyrolysis. Background technique [0002] The development of my country's economy has put forward the requirements of low energy consumption and low emission for the harmless treatment of garbage, especially the technology of harmless treatment of combustible garbage. Landfill, composting, and incineration are the three main ways of domestic waste disposal. Among them, waste incineration is a sustainable treatment method. The existing waste incineration technology generally chooses to use grate furnace or circulating fluidized bed furnace. This type of equipment has the characteristics of large investment and high operating cost in the process of use. Because it is peroxygen combustion, it is easy to generate various pollutants such as sulfur oxides and nitrogen oxides during the combusti...
