Most softened water equipment can only slow down the scale growth rate, but can not achieve the purpose of scale prevention. The water quality used by different users varies greatly in different regions. Jinan Gas fired hot blast stove In some construction sites, steam generators are used for steam maintenance of bridges because tap water cannot be used due to conditions. Only groundwater or river water can be used. At present, the hardness of many groundwater in China exceeds the standard, and the total hardness of water in some areas is high. vertical Gas fired hot blast stove factory It can reach several hundred millimoles, which is quite serious. I think the use of water softener is basically ineffective, because ordinary resin exchange water softener can only affect water with hardness of 7, which also ensures the use process. It needs to be cured regularly.

As a large equipment, the maintenance of gas-fired hot blast stove is one of the things that must be done. Jinan Gas fired hot blast stove Regular maintenance can not only keep the hot blast stove clean, but also improve the service life of the hot blast stove. Therefore, it is the top priority in the use of hot blast stove. Today's editor will tell you how to maintain the hot blast stove regularly. In many manufacturers that use hot blast stoves, in order to better develop the enterprise, it is necessary to increase the number of hot blast stoves and improve the performance of hot blast stoves. vertical Gas fired hot blast stove factory When enterprises purchase hot blast stove equipment, they must understand their own needs and the products of hot blast stove manufacturers in the market. Therefore, the small edition of gas-fired hot blast stove tells us the problems to be considered in the selection of hot blast stove.

The hardness of water is mainly formed and expressed by calcium and magnesium, so cation exchange resin (water softener) is generally used to replace Ca2+and Mg2+(the main component forming scale) in the water. With the increase of Ca2+and Mg2+in the resin, the efficiency of the resin to remove Ca2+and Mg2+gradually decreases. Jinan Gas fired hot blast stove When the resin absorbs a certain amount of calcium and magnesium ions, it must be regenerated. The regeneration process is to wash the resin layer with salt water in the salt tank to replace the hardness ions on the resin. With the regeneration waste liquid discharged from the tank, the resin will resume the softening exchange function. vertical Gas fired hot blast stove factory Since the hardness of water is mainly formed by calcium and magnesium and represents that the hardness of water is mainly formed by calcium and magnesium and represents the principle of sodium ion exchange and softening treatment, the principle is to pass raw water through sodium type cation exchange resin, so that the hardness components Ca2+and Mg2+in the water can exchange with the Na+in the resin, thereby adsorbing Ca2+ Mg2+， Soften the water.

The fluctuation of waste heat boiler flue gas in flow, temperature, composition, dust content and other aspects is one of its characteristics. The nature of the fluctuation can be regular, periodic, or irregular, aperiodic; The characteristics of fluctuation can be gradual. Jinan Gas fired hot blast stove It can also be impulsive; It can be a single parameter or a composite fluctuation of multiple parameters. The selection of waste heat boiler shall first analyze the whole cycle of the main process flow, and determine the flue gas characteristics of each time section in the cycle. vertical Gas fired hot blast stove factory Therefore, corresponding measures shall be implemented one by one in the design of waste heat boiler. The prominent feature is often the main basis for the selection of waste heat boiler.

System oil drainage: drain the heat transfer oil in the system when the circulating heat transfer oil is between 120 ± 5 (if the oil is not replaced, please find a clean container for proper storage) Prepare an appropriate amount of coke removal cleaning agent for the heat transfer oil system, drain the oil in the gas-fired heat transfer oil boiler system, and disconnect the cleaning system from the oil storage tank (close the valve), including the connection between the high-level tank and the oil storage tank. Jinan Gas fired hot blast stove Residual oil blowing steps: connect the air compressor at the pressure gauge or other places that can be connected, boost the system to 0.3-0.4MPa, and discharge it instantaneously; Repeat this process until the residual oil is blown out. The gas-fired heat transfer oil boiler, circulating pump, and other heat users form a cleaning circulating circuit for decoking and cleaning: add diluted cleaning agent to the system and fill it up to 1/2 of the water level of the high-level tank. Dosage of coke removal cleaning agent: 10~20%, the specific dosage shall be determined according to the scale thickness. Temperature: 90-95, time: 12-72 hours, which can be determined according to the scale thickness. Rinsing and cleaning: after cleaning, drain the residual liquid in the system and add clean water to rinse twice until the coke remover is free of foam and the water is clear. vertical Gas fired hot blast stove factory Temperature: 85-95, time: 5-8 hours Water blowing steps: after cleaning, connect the air compressor at the pressure gauge or other places that can be connected, use compressed air to boost the system to 0.3-0.4 MPa, and vent at each low point. Repeat this process until the water is blown out. Waste liquid treatment: the cleaning waste liquid generated in the cleaning process is discharged after being treated in the biochemical tank.

The waste heat boiler has advantages in the subdivided industry and is the leading enterprise in the industry. The company's main products are various types of waste heat boilers, industrial boilers, power station boilers, nuclear power equipment and power station auxiliaries. It is a research, development, design and manufacturing base for waste heat boilers with large scale and complete varieties in China. Jinan Gas fired hot blast stove Waste heat boiler is a typical energy-saving and emission reduction equipment. Its heat source can come from high-temperature flue gas waste heat, chemical reaction waste heat, combustible waste gas waste heat, and even can use high-temperature product waste heat. At present, the company has more than 20 series and more than 100 varieties of waste heat boiler products, which are widely used in steel, building materials, power, nonferrous metals, coking, chemical and other industries. vertical Gas fired hot blast stove factory In 2008, the company produced 272 sets of waste heat boilers of various types, with a total of 10268 steam tons, accounting for 34% of the comprehensive market share based on steam tons; According to the output value, the market share is 47%, ranking first in the waste heat boiler industry.
