Problems solved by technology

[0004] The above-mentioned prior art has the following problems: the regenerator is a honeycomb-shaped regenerator, the interior of which is through-shaped, and the outer wall is mostly a closed structure. Although this regenerator can preheat the newly entered organic waste gas, the preheating The volume of the newly entered organic waste gas has been reduced. Preheating the newly entered organic waste gas by simply rel

Example Embodiment

[0040] The present invention will be further described in detail below in conjunction with the drawings.

[0041] An exhaust gas combustion device for preventing the blockage of heat storage materials, such as figure 1 As shown, it includes an exhaust gas pipe 3 for transmitting organic waste gas, a preheating chamber 2 for preheating the organic waste gas in the exhaust gas pipe 3, a combustion chamber 1 for burning and purifying organic waste gas, and a combustion chamber 1 for recovering high temperature after combustion. A heat exchange chamber for the heat in the exhaust gas, and a filter chamber 6 for further adsorption and purification of the burned exhaust gas. The middle section of the exhaust gas pipe 3 passes through the preheating chamber 2, and the pipe section of the exhaust gas pipe 3 in the preheating chamber 2 is a preheating pipe 31 with good thermal conductivity.

[0042] A breathable partition 21 is provided between the preheating chamber 2 and the combustion ch...

Abstract

The invention discloses a waste heat recycling RTO combustion furnace, and relates to the field of gas combustion furnaces. The waste heat recycling RTO combustion furnace comprises a waste gas pipeline for transmitting organic waste gas, a combustion chamber for gas combustion, a preheating chamber for preheating the organic waste gas in the waste gas pipeline by using hot waste gas generated inthe combustion chamber, and a heat exchange chamber for recovering heat in the hot waste gas, wherein a heat storage cavity made of heat storage materials and a combustor used for increasing the initial temperature in the heat storage cavity to ignite the waste gas are arranged in the combustion chamber, the preheating chamber communicates with the combustion chamber, and a breathable partition plate is arranged between the preheating chamber and the combustion chamber. In order to solve the problem that an existing heat accumulating type gas oxidation combustion furnace cannot effectively preheat the organic waste gas, the waste heat recycling RTO combustion furnace has the advantages that the organic waste gas is preheated by using the combustion heat of the organic waste gas, and the preheating effect is better.

Description

technical field [0001] The invention relates to the field of gas combustion furnaces, more specifically, it relates to an RTO combustion furnace for waste heat reuse. Background technique [0002] Printed circuit boards, also known as printed circuit boards, are providers of electrical connections for electronic components. Printed circuit boards are mostly represented by "PCB". During the production process of PCB, organic waste gas will be produced, which contains toluene, methane and other gases. The waste gas has a strong pungent smell, and it needs to be burned to eliminate toluene, methane and other gases before it can be discharged. [0003] For existing harmful waste gas combustion devices, such as the Chinese patent with the patent publication number CN203116036U, it discloses a free RTO waste gas incinerator, including a furnace, the furnace is provided with a waste gas inlet and a waste gas outlet, and a burner is installed in the furnace. The furnace is equippe...
