AI Technical Summary

Technical Problem

In existing medical waste incinerator flue gas purification and acid removal tower devices, the fixed spraying of the spray heads is prone to spray blind spots, resulting in gas short circuits and ineffective purification of acidic pollutants.

Method used

The rotary spray system driven by a servo motor uses a rotating rod, bevel gears, and cross spray pipes to drive atomizing nozzles to form a spiral liquid curtain that covers the entire cross section of the tower. Combined with a filter box and filter frame, it achieves solid-liquid separation, enabling the atomized NaOH solution to fully react with the exhaust gas and treat the waste liquid.

Benefits of technology

It effectively avoids the injection blind zone, improves the reaction efficiency of acidic substances, reduces the risk of gas short circuit, and realizes solid-liquid separation and waste liquid recycling.

Abstract

This utility model discloses a medical waste incinerator tail gas purification and acid removal tower device, including a base. Three L-shaped fixing columns are fixedly connected to the upper surface of the base. One end of each of the three L-shaped fixing columns is fixedly connected to a spray tower body. A fixing plate is fixedly connected inside the spray tower body, and a protective cover is fixedly connected to the upper surface of the fixing plate. This utility model, by incorporating a servo motor, a rotating rod, a first bevel gear, a rotating tube, a second bevel gear, and a cross-shaped spray pipe, achieves this by rotating the first bevel gear, which in turn drives the rotating tube via the second bevel gear. The rotating tube then drives the cross-shaped spray pipe, which in turn drives multiple atomizing nozzles at the bottom to rotate. This causes the atomized NaOH solution sprayed from the nozzles to form a spiral liquid curtain, covering the entire cross-section of the tower body. This avoids blind spots in the spray, reduces the risk of gas short circuits, and ensures that the atomized NaOH solution fully reacts with the acidic substances in the tail gas.
