Cooling device for deamination tower and using method thereof

Abstract

The invention discloses a cooling device for a deamination tower and a using method thereof. The cooling device for the deamination tower comprises a deamination tower body and a temperature control water tank; the temperature control water tank is arranged on one side of the deamination tower body; a confluence hopper is fixedly connected to the bottom of the inner wall of the deamination tower body; a first connecting pipe is connected to the bottom of the confluence hopper; and a first water pump is arranged at the outer side of the deamination tower body. The cooling device for the deamination tower provided by the invention has the beneficial effects that the collected cooling water flow to be recycled is conveniently and preliminarily cooled through an air cooling mechanism, and the collected cooling water flow to be recycled is better filtered through a filtering mechanism, impurities are prevented from corroding the interior of a box body and blocking a pipeline, cooling water flow can be better guided through a spraying assembly so that the cooling water flow can be annularly diffused to the periphery, the cooling water flow can make full contact with the inner wall of the deamination tower body, and the cooling effect is improved.

Description

Technical field [0001] Technical Field The present invention relates to cooling apparatus, particularly as a means to cool the ammonia removal column and used methods. Background technique [0002] Deaminase tower i.e. ammonia stripping column, which is a principle: to ammonia (NH4 +) and free ammonia in the presence of primary ammonium ions state (NH3) in the waste water, the following equilibrium relationship: NH3 + H2O-NH4 ++ OH- this affected by the pH of the relationship, when the high pH, ​​equilibrium moves to the left, increasing the proportion of free ammonia. When the ambient temperature, pH value of about 7 when most ammonia ammonium ion state exists, and a pH of about 11, roughly 98% of free ammonia, free ammonia easily escape from the water, such as to be aerated, then may cause ammonia to escape from the water, where, PH is the key performance. And deaminase tower tower steam temperature will depend upon the thermal conductivity is raised after the long run, the nee...

AI Technical Summary

Problems solved by technology

However, after a long period of operation, the temperature of the deamination tower body will rise with the heat conduction of the steam, and it needs to be cooled. However, the cooling efficiency of the existing deamination tower cooling device is slow, and the cooling water flow cannot be collected and reused. Consumption is more serious
