Waste gas purification tower

Abstract

The invention relates to a waste gas purification tower. The waste gas purification tower comprises a tower body, and an air inlet and an air outlet are arranged at the bottom and the top of the tower body respectively. A filtering layer and a water-retaining layer are arranged in the tower body, the filtering layer and the water-retaining layer are sequentially arranged from bottom to top, and a spraying mechanism is arranged above the filtering layer. The spraying mechanism comprises an annular water pipe, and spray heads are uniformly distributed in the circumferential direction of the annular water pipe. The spray heads are communicated with an inner cavity of the annular water pipe, and water outlets of the spray heads are downward. A fan and a water pump are arranged on the outer side of the tower body, the air outlet of the fan is communicated with the air inlet at the bottom of the tower body, and the water outlet of the water pump extends into the tower body and is communicated with the annular water pipe. The structure is characterized in that a heater is arranged in the tower body below the filtering layer. The heater is a coil heater, and the water inlet and the water outlet are arranged on the coil heater. The waste gas purification tower is not only applicable to seasons with higher temperature, but also applicable to the cold seasons, and the range of applications is not limited.The waste gas purification tower is applicable to waste gas purification treatment on electroplating production lines.

Description

technical field [0001] The invention relates to an exhaust gas purification device. Specifically, it is an exhaust gas purification tower used to purify exhaust gas. Suitable for electroplating production line. Background technique [0002] The traditional exhaust gas purification tower includes a tower body, and the bottom and top of the tower body have an air inlet and an air outlet respectively. There is a filter layer and a water retaining layer in the tower body, the filter layer and the water retaining layer are arranged sequentially from bottom to top, and there is a spray mechanism above the filter layer. The spraying mechanism includes an annular water pipe, and sprinklers are evenly distributed on the circumferential direction of the annular water pipe. The spray head communicates with the inner cavity of the annular water pipe, and its water outlet faces downward. There are fan and water pump outside the tower body, the air outlet of the fan communicates with ...

AI Technical Summary

Problems solved by technology

Since the tower body is equipped with a spray mechanism, and the tower body is usually set outdoors, the ring water pipes and nozzles in the spray mechanism are easy to freeze in cold seasons, making the entire exhaust gas purification tower unable to work

Therefore, the traditional exhaust gas purification tower is only suitable for high temperature seasons, not for cold seasons, and its scope of application is limited
