Find a detailed process of condenser cleaning!! Thank you!

Condenser cleaning process.

1. Isolate the equipment system and drain the water inside the condenser.

2. Use high-pressure water to clean the sludge, algae and other impurities in the pipeline, and then close the system.

3 Install a ball valve (not less than 1 inch = cm) between the isolation valve and the exchanger, and install both the inlet and return ports.

4. Connect the transfer pump and connect the conduit so that the cleaning agent is pumped in from the bottom of the condenser and flows out from the top.

5 Start pumping the required Vorecotech cleaning agent into the condenser (the ratio can be adjusted according to the specific situation).

6 Repeat the cycle to the recommended cleaning time. As the cycle progresses and the sediment dissolves, the gas produced during the reaction also increases, and the excess air should be discharged through the vent valve at any time. As the air is discharged, the space inside the condenser will increase, so you can add the appropriate amount of water, and do not inject a large amount of water at the beginning, which may cause water to overflow.

7 The effectiveness of the cleaning agent should be checked regularly during the cycle, and the pH test strip can be used to measure it. If the solution is kept at pH23, then the cleaning agent is still effective. If the pH of the cleaning agent reaches 5 to 6, an appropriate amount of VorecoTech cleaning agent needs to be added.

The pH of the final solution was maintained at 2 3 for 30 minutes without significant change, proving that the cleaning effect was achieved.

Note: Foxtech cleaners can be reused after reuse, and the discharge will cause waste.

8 After the cleaning time is reached, ** wash the solution. And rinse the exchanger repeatedly with clean water until it is rinsed to neutral, and measure the pH value with pH test paper 6 7.

9. After the cleaning is completed, the machine can be started and operated. It is also possible to suppress the test to see if there is any leakage. If there is a leak, Mega Polymer composite materials can be used for repair and protection, and the service life of the equipment can be greatly extended.

10.After the equipment is stabilized, write down the current medium overflow, working pressure, heat exchange efficiency and other data.

11.By comparing the changes in the values before and after cleaning, it is possible to calculate the production costs such as electricity and coal costs saved and the improved work efficiency of the enterprise per hour, which is the value compensation of the company's application of Fuxtech technology.

12 The same operation method can also be used for plate and frame heat exchanger cleaning.

13.If the enterprise needs the equipment for passivation pre-film treatment, it can be operated according to the following process: the passivation pre-film agent is pumped into the equipment according to the recommended dilution ratio (and the test piece is hung in the circulation tank at the same time); Cycle and soak according to the recommended time; Detection of pre-film effect (red dot or blue dot method); Emission; Rinse with water until neutral (pH 6 7 measured with pH test paper).

14.After the passivation pre-film is completed, it is best to use ventilation equipment such as a fan to dry the system, which can ensure and improve the passivation pre-film effect.

I've found the address of the library for you.,,.

As a suggestion, there are special articles in the library.

The cleaning of the condenser is also called the descaling and cleaning of the condenser, which is divided into the pickling and passivation of the condenser and the high-pressure water jet cleaning of the condenser. Causes of condenser scale: The condenser cooling water system is an open circulation system, with the evaporation and drying of water, the concentration of dissolved salts (such as bicarbonate, sulfate, chloride, silicate, etc.) in the water increases, and some salts are precipitated due to supersaturation.

Condenser cleaning requires certain qualifications.

In addition, the cleaning equipment requirements are also more stringent, and the condenser chemical cleaning (high-pressure water jet cleaning) cleaning cycle circuit is:

Cleaning pump Temporary pipeline B side condenser inlet chamber B side condenser outlet chamber Temporary pipeline A side condenser inlet chamber A side condenser outlet chamber Temporary pipeline Cleaning tank.

The cleaning of the condenser is only suitable for the case of slight scaling of the tube, if the scale layer is thick and hard, or even seriously blocked, chemical cleaning, ultra-high pressure water jet cleaning, the effect is not ideal, to put it bluntly, it is not easy to use. The "iceberg descaling" method is the only effective method for descaling pipes with thick and hard scales, and even severely clogged ones. "Iceberg descaling" - mechanical method of removing stubborn scale:

No matter what kind of scale, no matter how serious the scale, no matter the serious blockage, the tube can be descaled clean and without damage.

"Iceberg descaling" - mechanical method of removing stubborn scale: imitated, without success, stunt in the brain. Let's take a look at the details, and you'll find out.

There are two kinds of cleaning of condenser: ** cleaning and off-line cleaning. Among them, the effect of ** cleaning is significantly better than that of offline cleaning. At present, a new technology for off-line cleaning is the use of spoiler belt (spiral link), which drives the link to rotate at high speed through the fluid power generated by the flow of water, which can prevent the formation of scale and remove scale on the one hand, and at the same time can also play a role in strengthening heat exchange.

It is such a product, developed by Wuxi Fordham Technology, which has been very well applied and achieved good results.

Go and see what Zhengzhou Saiwei has for mechanical and electrical equipment. Limit. For more than 10 years, the company.

With the innovative spirit of courage to change and the professional technical team, the company has independently developed the "Water Spider" series of condenser (or tubular heat exchanger) cleaning device, and pioneered the intelligent and efficient cleaning concept of robots; For all kinds of heat exchangers (plate, tube, heat network heaters), the "Maike" series of electromagnetic pulse cleaning machines and high-pressure water jet robot devices have been developed to solve the problem of heat exchanger cleaning under the operating state of the unit.

It is recommended to clean the condenser with FoxTech cleaning agent, which can effectively remove the most stubborn scale (calcium carbonate), rust, grease, slime and other sediments generated in the water equipment, and there is no corrosion to the equipment, which can greatly extend the service life of the equipment.

Nowadays, most of them are pickled and neutrally cleaned. It can also be cleaned with high-pressure water. The first two methods are better.

Cleaning with rubber balls, overhaul pickling or high-pressure water gun during operation.

Hangzhou Guanjie Industrial Cleaning Water Treatment Technology Co., Ltd. is the first to use special copper corrosion inhibitor and low-corrosion organic acid power plant condenser cleaning technology. When the condenser cleans the scale, the descaling efficiency is high, and the copper pipe of the condenser is basically non-corrosive. It has been appreciated by many cleaning customers.

The general chemical method is used to remove the condenser scale, and improper operation will cause corrosion to the condenser brass tube.

The condenser is one of the important equipment of the steam turbine generator. The quality of the condenser operation has a great impact on the safety of the operation of the unit, the economic production and disadvantages, the condenser of the power plant, if the water is not treated, the scale phenomenon will be very serious, once the scale, the copper pipe may be corroded, and affect the cooling effect of the condenser, causing the vacuum to drop.

The company specializes in various types of thermal power plant condenser scaling cleaning, copper pipe scale cleaning and slag leasing, using special copper corrosion inhibitor and organic acid with low corrosion rate of equipment plus accelerator and dispersant condenser chemical cleaning method. It has a low corrosion rate when cleaning and scaling the condenser, but it is very effective in dissolving the hard scale of the condenser, and can be used for cleaning the scale of the copper pipe of the condenser with dezincification corrosion. At present, it is the best cleaning method for heat exchanger cleaning and condenser cleaning and scaling, and Guanjie's chemical cleaning condenser technical solution has the advantages of high efficiency of cleaning condenser scale, low corrosion rate of copper pipes, and low engineering cost, especially suitable for condenser scaling cleaning of thermal power plants.

The power generation efficiency of the condenser is significantly improved after cleaning the scale.
