NMP Equipment Recycling System

Principle of absorption tower: Absorption tower makes use of the characteristics that NMP is miscible with water in any proportion and has high water solubility to treat NMP emission. The water absorption method can almost completely absorb NMP in exhaust gas.

Principle of rotor adsorption: VOCs molecular sieve rotor can adsorb large gas molecules like NMP at a specific temperature and desorption and regeneration can be achieved with high-temperature gas in specific areas of rotor, which can achieve recycling.

Principle

The NMP waste gas discharged from the coater reaches the filter box device through the exhaust pipe for purification and filtration, and then is sent to the waste heat recovery device and then to the condensing host device for cooling and condensation. Most of the NMP in the waste gas can be condensed out and enter the waste liquid system, and the concentration of NMP in the condensed waste gas is reduced to below 300ppm.

90~95% of the low-temperature waste gas after condensation is sent to the waste heat recovery device, where it exchanges heat with the high-temperature waste gas discharged by the coating machine, and then the low-temperature waste gas is heated to meet the return air requirement and sent back to the coating machine, thus fully realizing the heat energy recovery and saving the heating energy consumption required by the coating machine.

VOCS zeolite molecular sieve runner is divided into adsorption treatment zone, cooling zone and desorption zone, and driven by motor, which makes the runner rotate slowly, continuously adsorb and regenerate, and recycle tail gas. 5~10% of the condensed waste gas is mixed with the high temperature air in the desorption zone and enters the surface cooling section of the runner, where it is cooled and condensed, and most NMP can be condensed out and enter the waste liquid system. Then it is sent to the adsorption treatment area, and the air that meets the standard after adsorption can be exhausted to the outside by a fan.

In addition, a small amount of qualified air is recycled for heat exchange in the cooling zone, so that the air is heated and the runner is cooled. The heated air is heated by a heating device (steam heating or electric heating or heat transfer oil heating), and then the NMP on the runner zeolite is desorbed in the desorption zone, and the high-temperature air containing NMP in the desorption zone is sent to the surface cooling section of the runner. The whole runner process makes full use of the recycling of heat energy and saves the heating energy consumption required by the coating machine.

5~10% of the low-temperature waste gas after condensation is sent to the spray tower device. The spray tower uses the characteristics that NMP can be mutually soluble with water at any ratio and has high water solubility to circularly rinse and absorb the waste gas. After the NMP concentration in the liquid phase of the tower bottom reaches the set value, it enters the waste liquid system, and the gas-liquid separator is used at the top of the tower to separate and demist, so that the NMP in the waste gas is completely absorbed, and the concentration of the discharged tail gas meets the national environmental protection requirements.

Spray Tower

The spray tower is designed to reduce and purify the NMP content in the exhaust air generated during the coating machine production process, in order to meet the environmental requirements and safely discharge the exhaust gas into the atmosphere.

The principle involves thorough contact between the gaseous NMP present in the exhaust air and water through spraying. This allows the originally mixed NMP in the exhaust air to dissolve in the water, achieving a reduction in NMP content and the purification of the exhaust air.

The advantages of Pengjin's spray tower include low energy consumption and better purification effectiveness compared to similar products in the industry.
