Operation specification for cleaning and disinfecting air-conditioner cooling tower

Abstract

The invention relates to an operation specification for cleaning and disinfecting an air-conditioner cooling tower. The operation specification is characterized by including the following steps that 1, field investigation and preparation are performed, specifically, field investigation of normal running states of the cooling tower is performed, the actual situation is analyzed, and then an individualized operation scheme is worked out; an investigator needs to prepare personal protection very well, like wearing a mask and a pair of goggles; and key points of field investigation lie in that (1) dirt, algae and corrosion degrees of a water distributor, a filler, a tower tray (water collecting tray) and a backwater filtering net are investigated, (2) the investigator needs to know the situation of water replenishment of the cooling tower, (3) whether a water replenishing valve and a sewage discharge valve are intact or leak water or not is checked, (4) the investigator needs to know the corrosion degree of a support of the cooling tower, (5) whether an exhaust outlet is aligned to the cooling tower or not is checked, for oily fume increases the cleaning difficulty, and (6) an investigation report or advices are written, a plan is worked out, and suitable cleaning and disinfection agents, tools and equipment are prepared.

Description

technical field [0001] The invention discloses an operating procedure for cleaning and disinfecting an air-conditioning cooling tower, which is a technical specification to be followed for cleaning and disinfecting an air-conditioning system cooling tower and cooling tower water, and belongs to the technical field of cleaning and disinfecting an air-conditioning cooling tower. Background technique [0002] Cooling towers are mostly built outdoors, with sufficient sunlight and sunshine, and communicated with the atmosphere so that the cooling water can absorb various pollutants in the air, and the uninterrupted supply of water can bring new nutrients, a steady stream and a variety of sources. Nutrients make algae and microorganisms in the cooling tower, especially pathogenic microorganisms (such as Legionella), multiply and become a potential source of disease pollution; The open cooling tower of the air conditioner shall be cleaned no less than once a year, and Legionella pn...

Problems solved by technology

[0002] Cooling towers are mostly built outdoors, with sufficient sunlight and sunshine, and communicated with the atmosphere so that the cooling water can absorb various pollutants in the air, and the uninterrupted supply of water can bring new nutrients, a steady stream and a variety of sources. Nutrients make algae and microorganisms in the cooling tower, especially pathogenic microorganisms (such as Legionella), multiply and become a potential source of disease pollution; The open cooling tower of the air conditioner shall be cleaned no less than once a year, and Legionella pneumophila shall not be detected in the water of the cooling tower after cleaning, and the accompanying WS 396 -2012 "Cleaning Specifications for Centralized Air Conditioning and Ventilation Systems in Public Places" was issued to guide the cleaning of the air conditioning system. Cleaning; the following disadvantages exist in the use of this cleaning specification: Due to the lack of detailed and feasible operating procedures, the current social cleaning institutions in my country are mixed, and their operations are not standardized. In particular, the current cleaning institutions do not need to obtain relevant cleaning qualifications to work, resulting in a mere formality of the cleaning process; The specification does not strictly limit the effective concentration and continuous disinfection time during disinfection, which makes it difficult to achieve the expected disinfection effect. In actual work, it is found that Legionella pneumophila can still be detected in some air-conditioning cooling towers after cleaning; (3) the specification does not Pre-film treatment after cleaning and disinfection is required, and the surface pre-film can prevent and disperse various scaling ions from scaling, so as to achieve the purpose of anti-corrosion, anti-scaling and preventing the growth of microorganisms (especially Legionella)
