Waste heat recycling device for organic waste gas treatment

Abstract

The invention discloses a waste heat recycling device for organic waste gas treatment. The waste heat recycling device comprises a plurality of coil pipes; pipe openings at the two ends of each coil pipe are horizontally formed, and one of the pipe openings is short; the two ends of each coil pipe are located at the same height, and a connecting pipe is fixedly inserted into the end, with the short pipe opening, of the coil pipe; and inserting rods and sleeves are fixedly connected to the two sides of the coil pipes in parallel, the inserting rods are matched with the sleeves, and the inserting rods and the sleeves are close to the tops and the bottoms of the coil pipes respectively. According to the waste heat recycling device, by arranging stop blocks, during coil pipe connecting, when the inserting rods make contact with baffles, T-shaped pipes are screwed, the stop blocks are inserted into the gaps between the sleeves and the inserting rods, in the process, the inserting rods pull trapezoidal rotating plates to move in the direction where the stop blocks are located, the trapezoidal rotating plates and strip-shaped holes are tightly clamped together, then high-temperature gas is introduced into the coil pipes to heat a conveying pipeline, the coil pipe at the tail end can provide corresponding hot air for a factory after being connected with the guide pipe, and thus, reasonable utilization of high-temperature waste gas is realized.

Description

technical field [0001] The invention belongs to the technical field of organic waste gas recovery and utilization devices, in particular to a waste heat recovery and utilization device for organic waste gas treatment. Background technique [0002] Organic waste gas is generally flammable and explosive, toxic and harmful, insoluble in water, soluble in organic solvents, and difficult to treat. In the treatment of organic waste gas, various principles such as organic waste gas activated carbon adsorption treatment method, catalytic combustion method, catalytic oxidation method, acid-base neutralization method, and plasma method are generally used. Generally, the plasma method is recommended because the low-temperature plasma method has high removal efficiency. However, some organic waste gases contain a large amount of high-temperature waste gas, and the treated and absorbed waste gas is discharged into the atmosphere, which will still cause high-temperature pollution and affe...

[0002] Organic waste gas is generally flammable and explosive, toxic and harmful, insoluble in water, soluble in organic solvents, and difficult to treat

In the treatment of organic waste gas, various principles such as organic waste gas activated carbon adsorption treatment method, catalytic combustion method, catalytic oxidation method, acid-base neutralization method, and plasma method are generally used. Generally, the plasma method is recommended because the low-temperature plasma method has high removal efficiency. High and easy to use, however, some organic waste gas contains a large amount of high-temperature waste gas, and the exhaust gas after treatment and absorption is discharged into the atmosphere, which will still cause high-temperature pollution and affect the surrounding environment

[0003] At present, in some cold regions, some transmission pipelines are exposed to the air. In low temperature environment, these pipelines are easy to be damaged by freezing and cracking. To heat the pipelines with the high-calorie waste gas treated by the factory, it is necessary to use a coil tube, and the length of the coil is fixed, so it cannot be changed according to the length of the delivery pipeline, which increases the difficulty of using high-temperature exhaust gas and causes heat loss
