AI Technical Summary

Problems solved by technology

However, the heater does not fully heat all the gas, and the heater becomes dirty and does not transfer heat effectively
They are also overwhelmed by particulate contaminants or reaction products that prevent the free flow of gas through the cleaning system
Periodic cleaning of heaters and cavities is necessary, necessitating shutting down the system, or removing the processing equipment from the production line, requiring a separate system and more cost

Embodiment Construction

[0059] figure 1 A dynamic oxidation system 10 is shown. The top 11 is provided with an industrial waste gas inlet connection channel 13 , an oxidized gas discharge 19 , nitrogen connection channels 15 and 17 for scrapers and connected to a drive cylinder 29 .

[0060] The front portion 21 of the storage cabinet 20 is provided with a control panel 23 and an inspection door 25 . Horizontal box corner 27 stabilizes the storage cabinet.

[0061] Extending from the top 11 is a scraper operating cylinder 29 . Cylinder 29 may be bi-directional, driven in opposite directions, or uni-directional, driven downwards and returned by gas or mechanical springs.

[0062] figure 2 Shown is a dynamic oxidation system 10 . The industrial waste gas 1 enters one or two inlets 31 and flows through the cavity 33 in which four, eight or more thermal ceramic cylinders 37 heat the combustible industrial waste gas to auto-ignition temperature. Electric heating rods 35 heat the hot cylinder 37 int...

Abstract

The invention discloses dynamic oxidation of industrial waste gas. According to the technical scheme provided by the invention, the harmful industrial waste gas is heated to spontaneous ignition temperature through a heating rod and a cylinder in a heating cavity; a heating sleeve is mixed with oxygen in a combustion chamber, the gas spontaneously ignites and combusts. Air is introduced to cool and combust. Particles are separated from cooled gas. Pure harmless gas and air are discharged.

Description

technical field [0001] The present invention relates to methods and apparatus for reducing or eliminating harmful gas emissions. Contaminated gases are broken down, cleaned and neutralized. The invention is particularly relevant for use with global warming gases and other gases which are difficult to decompose. These gases include perfluorocarbons (PFCs), tetrafluoromethane (CF 4 ), hexafluoroethane (C 2 f 6 ) and many other ozone depleting global warming and greenhouse gases. The present invention can also remove arsenic trihydride (AsH 3 ) or phosphine trihydrogen (PH 3 ) and other gases, which are used to decompose the decomposition of the exhaust gas flow in the semiconductor process. High temperatures are required to clean, neutralize and break down these types of gases. Background technique [0002] Existing systems do not provide sufficient heat to effectively remove global warming gases from the exhaust air stream. Previous gas cleaning systems included cont...
