Description

Technical Field

[0001] This utility model relates to the field of catalytic furnace technology, specifically a chemical catalytic furnace with high sealing performance. Background Technology

[0002] A chemical catalytic furnace is a device that accelerates chemical reactions using catalysts. It is widely used in industrial chemical processes, such as petroleum refining, chemical production, and environmental protection. By providing suitable reaction conditions, it significantly increases the reaction rate and allows reactions to occur under milder conditions, saving energy and improving product selectivity. The basic principle of a chemical catalytic furnace is to use a catalyst (such as a metal, metal oxide, or acid-base catalyst) to accelerate a specific chemical reaction. During the reaction, the catalyst itself does not participate in the final products; it merely provides the activation pathway, lowering the activation energy required for the reaction, thus allowing the reaction to proceed at lower temperatures and pressures.

[0003] The existing technology has the following shortcomings: The existing technology, disclosed in CN202111370476.0, discloses a highly sealed chemical catalytic furnace, including a base, a mounting platform, a catalytic furnace, a catalytic tube, a pump body, a heating furnace, a heating tube, and a fuel tank. The mounting platform is mounted on the surface of the base, and the catalytic furnace is fixedly connected to the surface of the mounting platform. The catalytic tube is installed inside the catalytic furnace. The heating furnace is fixedly connected to the bottom surface of the mounting platform, and a heating tube is mounted on the heating furnace. The heating tube penetrates the mounting platform and the catalytic furnace, inserting into the interior of the catalytic furnace. The catalytic tube is spirally sleeved on the surface of the heating tube. Both ends of the catalytic tube penetrate the catalytic furnace and are exposed to the outside. A solenoid valve is fixedly connected to the top end of the catalytic tube, and the bottom end of the catalytic tube is installed inside a waste gas tank.

[0004] The furnace body of the above-mentioned equipment is an integrated design, which can effectively improve the sealing performance, but it is inconvenient to clean the inside during use, which limits its operation. In addition, the whole device lacks a self-early warning mechanism, which can easily cause safety hazards when gas leaks. Utility Model Content
