AI Technical Summary

Technical Problem

Existing ammonia absorption towers suffer from problems such as poor sealing of the drain valve due to factors like skewness, wear, deformation, and spring fatigue. This leads to reduced ammonia absorption efficiency, decreased efficiency of the cyclone gas-liquid separator, and delayed system startup.

Method used

The drain valve, which employs a floating valve core and ball joint connection structure, combined with a flexible anti-corrosion sealing sleeve and gravity block drive, ensures coaxial sealing between the valve core and the valve cover, avoiding incomplete closure due to misalignment or wear.

Benefits of technology

This technology achieves efficient gas-liquid contact and mass and heat transfer in the ammonia absorption tower, ensuring reliable sealing, improving ammonia absorption efficiency, meeting environmental emission standards, and simplifying system maintenance.

Abstract

This utility model relates to the field of industrial waste gas treatment equipment, specifically to an ammonia absorption tower. The tower body, arranged from top to bottom, includes a cyclone gas-liquid separator, an ammonia spray assembly, a turbulence assembly, and a liquid collection chamber. An air inlet pipe is located above the liquid collection chamber, with the bottom of the chamber connected to an output ammonia pump and the upper part connected to the liquid inlet pipe. The cyclone gas-liquid separator is installed inside the air collection pipe at the top of the tower body, with its upper outlet connected to an exhaust pipe, an atomizer installed at the middle air inlet, and a drain valve installed on the bottom liquid phase pipe. This utility model enables the sealing pair to automatically correct radial and angular deviations each time it is closed, preventing ammonia-containing tail gas from bypassing the liquid phase pipe. The entire tower utilizes a synergistic gas-liquid contact and mass transfer / heat transfer system, employing measures such as uniform air distribution, enhanced turbulent mass transfer, internal cooling heat transfer, and efficient liquid atomization to systematically improve the overall ammonia absorption efficiency from multiple aspects.
