Problems solved by technology

[0002] In the cold winter, more than 85% of the heating in northern my country uses hot water heating systems with water as the working medium, and some heating users willfully steal a large amount of hot water for bathing, laundry, mopping, car washing, etc. Loss of water leads to the following problems: 1) Due to excessive water loss, the balance of the secondary heating network system is out of balance, and the heat cannot be supplied normally; 3) The waste of fuel, water, and electricity resources keeps the heating cost high; 4) Increases the workload of the fireman
Under normal circumstances, the daily replenishment of water for a heating area of ​​200,000 square meters should not exceed 40 tons, but in fact, due to illegal users stealing water, the daily replenishment amount reaches 60-80 tons. The serious loss of water also leads to the CO of the entire water system. 2 The corrosion is aggravated, and the correct water treatment method is adopted to achieve energy-saving, water-saving, environmental protection, low-consumption and high-quality operation of the heating system
[0003] In the heating and heating water system, the heat transfer medium is water. If the water treatment is not done well, it will inevitably lead to scaling, corrosion, increased maintenance and shortened service life of the heating equipment.
It will also inevitably lead to waste of energy, waste of water resources and environmental pollution

Abstract

The invention relates to the field of heating water treatment, in particular to a non-toxic and non-corrosive heating water odorant. The heating water odorant at least comprises the following components in parts by weight: 40-60 parts of starch, 10-20 parts of allicin, 10-15 parts of mercaptan, 5-10 parts of thiosulfate, 25-35 parts of an alkaline agent and 15-25 parts of water. The prepared non-toxic and non-corrosive heating water odorant is widely applied to hot water boilers, pipe networks for heat supply of various heat exchangers and the like to form an intensive irritating stinky smell.The water odorant has easy operation, wherein the softening and stabilizing effects are achieved on the water quality; when leakage happens to the pipeline, the pipeline cannot be blocked, easily sniffing by people, the water leakage phenomenon is found, the maintenance progress is accelerated, and no corrosion is caused to copper, aluminum, stainless steel and the like existing in the heat distribution pipeline. By means of the water odorant, heating equipment damage caused by excessive corrosion of products can be avoided, manual system water loss can be thoroughly prevented, the heat distribution pipeline is an ideal energy-saving agent for preventing hot water loss, and the heating water cost and the fuel consumption cost are effectively reduced.
