Description

Technical Field

[0001] This utility model relates to the technical field of organic waste gas treatment equipment, and in particular to an RTO device for efficiently treating organic waste gas from coating processes. Background Technology

[0002] RTO (Regenerative Thermal Oxidizer) equipment for treating organic waste gas is a highly efficient device for treating organic waste gas. It mainly decomposes organic waste gas through high-temperature oxidation, converting it into harmless substances such as carbon dioxide and water vapor, while simultaneously achieving energy recycling. RTO waste gas treatment equipment is widely used in the automotive and machinery manufacturing industry, electronics manufacturing industry, light industry, metallurgical and steel industry, chemical industry, and petroleum refining industry. In the automotive and machinery manufacturing industry, it is commonly used for treating organic waste gas in painting lines and drying rooms.

[0003] A search revealed that authorization announcement number CN210934418U discloses an RTO (Regenerative Thermal Oxidizer) organic waste gas treatment device for automotive painting. The device includes a main body with an exhaust pipe on its outer side and a connection port on its outer side. A spray tower is located on one side of the first partition, and a fan is located on the outer side of the second partition. A baffle is rotatably connected to the main body via a hinge. An adsorption screen is located on the inner side of the third partition. A receiving tray is connected through the spray tower, and the adsorption screen is connected to the third partition via a threaded rod. This device is rationally designed. The slider facilitates the sliding removal of the third partition for replacing the adsorption screen. The threaded rod and nut ensure stable placement of the adsorption screen within the third partition and facilitate disassembly and installation. Since not all the chemical is absorbed, excess chemical falls into the receiving tray due to its weight, allowing for collection and reuse, thus achieving environmental protection, energy saving, and no waste.

[0004] However, existing RTO equipment for treating organic waste gas cannot effectively recover and utilize the heat generated during the treatment process, which leads to resource waste. Therefore, there is an urgent need in the market for an efficient RTO equipment for treating organic waste gas from coating processes to solve these problems. Utility Model Content

The heated water is discharged and collected from the water outlet seat 1203. This can recover heat and avoid waste of resources. It should be noted that, in order to save space and highlight the innovative elements of this patent, such as the specific working principle and working process of the RTO equipment for organic waste gas, it will not be described in detail in this patent.

The heated water is then discharged from the water outlet 1203, recovering heat and preventing resource waste.
