Introduction of a cooling tower cleaning economical and simple way


It directly affects the role of the cooling effect, a cost of using water,[link widoczny dla zalogowanych], I passed several tests, the original plan to use the cleaning methods reduced the expenditure of 20,000 yuan, 120 yuan, will be shortened to 3 days 4 hours economical and simple and very good cooling effect. Key words cooling tower cleaning hydrochloric acid. 1, the background is a small refrigerator in our hospital library life,[link widoczny dla zalogowanych], because in recent years, the continuous improvement of living standards, frozen skin soft market, the units and the catering industry are caused by individual households have to live mainly meat, which to cold storage resulted in waste, can not reflect its value, especially when we are so small cold storage units do not have much more of the purposes, and stopped also feel pity, we can only maintain the status quo of foreign rental, replacement of outdated equipment and are unable to invest. 2, the operational status of the cooling tower cooling tower in our hospital cold storage installation in 1980, causing exercises had been there for 27 years, in the first 10 years of operation Chaixi Tim had expected part of the tower, then the running time too long , combined with our water quality is not good, thick, hard-scale materials and Tim formed the overall scale is not even out of recycled water, heat dissipation is poor, began to replace Tim materials, workers dug with a stone drill rod 3 is issued dug less than a quarter hours, due to the aging of materials digging Tim Tim materials and scale have all been dug into the broken foam, cooling towers can not be used more, the water pump on the surface of a material to open Tim had 5 cm of water , recycled water can only flow from the cooling towers around the cooling tower, water everywhere on the ground, when the cooling effect even worse, out of the water temperature is almost equal to the pressure with an increasing condensation. Compression ratio rose to more than 8, when the cooling effect is very poor, the only way to replace the cooling tower only, but not because the benefits of cold storage, cooling towers need ten thousand yuan of share capital, together with the new tower demolition of the old Taan The cost of close to 2 million, no funds first unit, the second time too late, there are hundreds of million of goods, cold storage, so the cooling towers can not be replaced, I would like to use hydrochloric acid cleaning, consultation with experts, not cleaning the cooling tower precedents, are generally replaced. 3, experimental research possible options for cleaning in desperate circumstances, I determined to clean the cooling tower, the first to take a test sample scale, how much percentage of hydrochloric acid to dissolve the scale, and the melting of a time, but also consider the hydrochloric acid on the metal tower corrosive effect, and the length of time, because the main cooling tower of steel and plastic material is glass, but there are small amounts of metal materials, such as the fan blade is aluminum products, water is the steel flange parts, sub-central pillar of copper pipe All of these have a pretty good idea, after several test hydrochloride on the glass, steel, plastic does not corrode, but the iron and steel, its corrosion of aluminum is quite calendar harm, after analysis of the corrosion that the flange does not matter, because it is relatively thick and have relatively thick surface scale, mainly in need of special care to protect the fan blades, thus fully grasp the nature of the various portions of the material, corresponding to the feasibility program. 4, the program's facilities to operate in order to prevent burns and poisoning, the first operator to wear protective gloves (anti-acid) and overalls, first drain the cooling tower, wrapped in plastic film tight blocking of the plate to prevent the hydrochloric acid corrosion of pipes, and then the fan blades with a plastic bag to pack, to prevent corrosion of aluminum in hydrochloric acid and then spray with plastic products, from the cooling tower at the top of a uniform spraying of 30% hydrochloric acid, hydrochloric acid and scale that immediately react, bubble is l onwards, when the spray nozzle into the bottom of the bubble, following the (continued on page 56) for a 53 - \Powder,[link widoczny dla zalogowanych], foam rose higher and higher, then quickly stir with a wooden stick about the bubble will drop down,[link widoczny dla zalogowanych], so that repeated operations to continue spraying, to add material to the foam from the bottom of the leak, indicating the scale between the material and with Tim the larger the gap, have been washed through the cooling tower, circulating water will flow evenly down, cleaning the cooling tower was successful. 30 tons of cooling tower with a 150 kg of hydrochloric acid, hydrochloric acid 30% the cost of only 0.8 yuan per kilogram, 120,[link widoczny dla zalogowanych], 2 people can operate on manual, time just 4 an hour to complete a 56, good results . 5, the concluding remarks of the original plan for expenditure of the cooling tower need 2 million new tower demolition of the old Taan takes 3 days, with the cleaning methods not only save money, but also save time, the operation is very simple, is a good way to clean the cooling tower, for your reference.
