Description

Integrated RTO Regenerative Oxidation Furnace

technical field

The utility model relates to the technical field of organic waste gas treatment equipment, in particular to an integrated RTO oxidation furnace system with simple structure and high heat energy utilization rate.

Background technique

In recent years, the rise of chemical and various production and manufacturing enterprises has brought serious environmental pollution while providing energy and material needs for the entire society. At present, the mainstream treatment process can already deal with most of the organic waste gas of enterprises. However, some enterprises not only have a large amount of emissions, but also the pollutants in them are not suitable for treatment by absorption, plasma and other processes, and can only be treated by combustion destruction.

Regenerative thermal oxidation furnace is a kind of high-efficiency organic waste gas treatment equipment. Its principle is to oxidize combustible waste gas into corresponding oxides and water at high temperature, so as to purify waste gas. Compared with the traditional catalytic combustion and direct-fired thermal oxidation furnace (TO), RTO has the characteristics of high thermal efficiency (≥95%), low operating cost, and can handle large air volume and low concentration exhaust gas. Secondary waste heat recovery greatly reduces production and operation costs.

However, the structure of the existing RTO equipment is relatively complex, the pipeline connections are complicated, and the gas forms internal turbulence in the pipeline, which not only increases the pressure loss of the entire device, but also reduces the preheating effect and combustion effect, wastes fuel resources, and increases operating costs.

Contents of the invention

The purpose of this utility model is to overcome the defects existing in the prior art and provide an integrated RTO heat storage with good heat preservation effect, while reducing internal pressure loss, improving the working efficiency of the whole device, and reducing energy consumption and operating costs Oxidation furnace.

The technical solution for realizing the purpose of this utility model is: an integrated RTO regenerative oxidation furnace, which has a pre-pretreatment filter device, an integrated furnace body and a centrifugal fan arranged in sequence; the output end of the pre-pretreatment filter device It communicates with the main gas inlet valve on the shell of the integrated furnace body; the integrated furnace body has two identical furnace bodies, and each furnace body includes a combustion chamber and a heat storage chamber; the heat storage chamber is equipped with a porous high temperature Ceramic packing layer; the porous high-temperature ceramic packing layer is separated from the furnace body to form an internal airflow pipeline controlled by an electric valve that guides the flow of gas; the centrifugal fan communicates with the main gas outlet valve on the integrated furnace body shell.

An inspection door is installed on the integrated furnace body described in the above technical solution.
