Embodiment Construction

[0027] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0028] The present invention provides a high-temperature pyrolysis reactor for reducing the dust content of oil and gas. Mainly through the structure of the pyrolysis reactor itself, gas-phase dry dust removal is performed on the pyrolysis gas, so that it has the function of self-dust removal, so as to reduce the dust content of the pyrolysis gas outlet. , simplify the subsequent dust removal process system of pyrolysis gas, and reduce the difficulty of pyrolysis oil treatment.

[0029] like Figure 1-5 As shown, a high-temperature pyrolysis reactor for reducing the dust content of oil and gas according to the present invention includes a pyrolysis reactor shell 1, a reactor material inlet 2, a louver baffle 3, a swirl device 4, and a pyrolysis gas outlet 5. Pyrolysis solid product outlet 6. Among them, the cyclone device 4 is divided into ...

Abstract

The invention belongs to the technical field of garbage pyrolysis, and particularly relates to a high-temperature pyrolysis reactor for reducing the dust content of oil gas. The pyrolysis reactor shell adopts a stepped structure with a small front part and a large rear part, the front end is provided with a reactor material inlet, and the tail part is provided with a pyrolysis solid product outlet; and the rear middle portion of the reactor shell is a shell amplification section, a protruding cavity in the upper portion of the amplification section serves as a pyrolysis gas outlet area, a shutter baffle is arranged at a gas phase inlet of the area, a rotational flow device is arranged in the area, a pyrolysis gas outlet is formed in a gas phase outlet, and the pyrolysis gas outlet is a rotational flow device outlet. And the rotational flow device and the pyrolysis gas outlet are arranged above the pyrolysis solid product outlet. By utilizing the structure of the pyrolysis reactor, the pyrolysis gas is subjected to gas-phase dry-type dust removal in the pyrolysis reactor, so that the dust content of a pyrolysis gas outlet is reduced, the subsequent dust removal process configuration of the pyrolysis gas is simplified, and the pyrolysis oil treatment difficulty is reduced.

Description

technical field [0001] The invention belongs to the technical field of garbage pyrolysis, and in particular relates to a high-temperature pyrolysis reactor for reducing the dust content of oil and gas. Background technique [0002] When pyrolyzing garbage, the generated pyrolysis gas has a high dust content, and the dust-containing pyrolysis gas has the characteristics of high temperature (>500°C), easy phase change, easy bonding, and strong adhesion. , in the pyrolysis gas purification system, it is very easy to cause pipeline blockage and quenching equipment failure, and the system is forced to stop in an emergency; The dusty tar produced after quenching is also extremely difficult to handle, resulting in poor fluidity of the pyrolysis oil, reducing the quality of the pyrolysis oil, and increasing the difficulty of oil treatment. At present, pyrolysis gas dust removal is a major difficulty in the pyrolysis device, which affects the stability and continuous operation of...
