HOW TO CLEAN THE COOLER?
1 scaling reasons
(1) fluid flow rate. The flow rate of the fluid can affect fouling through the influence of heat and mass transfer and mechanical forces, and the influence process is very complicated. In fact, the effect of flow rate on different types of fouling is different, and the extent of fouling of different types of heat exchange equipment is not the same. In heat exchangers, the effect of flow rate on fouling should be considered simultaneously for both fouling and fouling, and for all types of fouling, the rate of fouling increases more rapidly than fouling due to the increased flow rate, So the rate of dirt growth decreases with increasing flow rate. However, in actual operation, the increase of flow rate will increase the energy consumption, therefore, the flow rate is not as high as possible, should be considered both energy consumption and dirt.
(2) fluid properties. The properties of a fluid include the nature of the fluid itself and the nature of the various substances that are not dissolved or entrained in the fluid. In cooling water systems, the water quality characteristics play a key role in the deposition of foulants. If they contain salts and other substances, they may crystallize due to changes in temperature or concentration. If they contain undissolved gases, the corrosion of metal surfaces will be affected. If they contain microorganisms and nutrients It also affects biological fouling.
(3) heat transfer wall temperature. The fluid temperature and its heat transfer coefficient determine the interface temperature. The rate of chemical reaction depends on the temperature and the biological fouling also depends on the temperature. Increasing fluid temperature generally leads to an increase in chemical reaction rate and biofouling velocity, which affects the amount of fouling deposited, resulting in an increase in fouling rate.
(4) heat transfer equipment parameters. First, the heat transfer surface material: usually scaling and materials have a great relationship. The study found that copper alloy material on the biological fouling inhibition. For other commonly used carbon steel, stainless steel, only through the deposition of corrosion products and affect the scaling, and if the corrosion resistance of graphite or ceramics and other non-metallic materials, is not prone to scaling. Second, the heat transfer surface state: the surface quality of the heat transfer surface material will affect the formation and deposition of dirt, the greater the surface roughness, the more conducive to the formation and deposition of dirt. Third, the structure of the heat exchanger: Experience shows that the general plate heat exchanger and spiral plate heat exchanger anti-fouling performance is better than the shell and tube heat exchanger.
2. descaling measures
2-1 Mechanical Cleaning Mechanical cleaning is the removal of dirt adhering to the surface by providing a force greater than the adhesion of the fouling agent. This cleaning method removes carbide fouling and hard fouling that can not be removed chemically. Mechanical cleaning methods can be divided into the following two categories: (1) strong cleaning. Powerful cleaning method is the use of injection equipment will be injected into the medium with a very high impact heat exchanger tube side and shell side, played the purpose of descaling. Common strong cleaning method with shot peening, high pressure water jet cleaning, jet cleaning, sandblasting cleaning, strong pig etc. One of the high-pressure water jet cleaning used to remove carbonized scale or hard scale, but only rely on the impact can not be removed but must rely on heat to make it loose dirt, then the use of steam jet cleaning. (2) soft mechanical cleaning. This cleaning method relies on the insert in the tube movement, contact with the inner surface of the tube, to achieve the effect of removing dirt. This kind of soft mechanical cleaning is also called online mechanical cleaning. Common methods are rotating helix method, liquid-solid fluidization method, rotating tie method, coil spring vibration method, sponge glue ball online cleaning method. Inserts of various types, including the sponge rubber ball method is slightly larger than the diameter of the tube diameter sponge balls squeezed into the tube for descaling purposes, you can also use a wire brush to clean the dirt of a lower hardness.
2-2 Chemical Cleaning Chemical cleaning is the use of chemical cleaning fluid, resulting in a chemical reaction that heat exchanger tube surface scale and other deposits dissolved, peeling or peeling. This method of cleaning time is short, simple operation, descaling completely clean, is currently the widely used and effective cleaning methods. Chemical cleaning can be done in the field, labor intensity lower than the mechanical cleaning and cleaning more completely, you can clean the mechanical cleaning can not reach the place, and to avoid mechanical cleaning on the heat transfer surface caused some mechanical damage; and chemical cleaning can not open Equipment, can not be disassembled shell and tube heat exchanger with mechanical cleaning incomparable advantages. Before cleaning, should understand the structure of the cleaning equipment, materials, the distribution and thickness of dirt and its composition, so as to reasonably choose to clean the main agent, corrosion inhibitors, and additives, and choose the appropriate amount of detergent, concentration, speed , Temperature and time, the last should be done to deal with waste disposal of waste discharge, to avoid the impact on the environment.
2-3 Physical Cleaning Physical cleaning is the use of a variety of mechanical force and energy to make the dirt crushed, separated and stripped off the surface of the object, so as to achieve the cleaning effect. Common methods are, ultrasonic cleaning, PIG pigging technology, electric field descaling technology. Ultrasonic cleaning is the use of ultrasonic cavitation effect, activation effect, shear effect and inhibitory effect, which play a descaler effect. Ultrasonic cleaning technology is the key to select the appropriate ultrasonic power and frequency of size and temperature of the cleaning fluid.
2-4 microbial cleaning With the increase of HRT, COD removal rate gradually increased. When HRT> 5min, COD removal rate basically stabilized and COD removal rate reached about 75. In the electrochemical reactor, due to the fluid flow and gas agitation, greatly increased the particle collision and growth opportunities. The average particle size of air bubbles produced by electric floatation is 20 ~ 70μm, with a relatively large specific surface area, which can provide more adsorption and bonding centers for the flocs and make the flocs have gas inside, which is more conducive to floc floating. Therefore, in a relatively short period of time can be satisfied with the treatment effect.
2-5 current intensity of the impact of laundry wastewater turbidity, COD and MBAS removal rate and current intensity relationship. With the increase of the current intensity, the removal rate of these indicators gradually increased. According to Faraday's law of electrolysis, the electrochemical dissolution of Al and the electrolysis of water are proportional to the amount of electricity supplied (I / t). When 1F (26.8Ah) is passed, 9gAl3 can theoretically be eluted and 0.0224Nm3H2 and O2 can be released at the same time, which is far greater than the amount of gas released in DAF. At the same time increase the current intensity can get smaller bubbles, the flotation separation process is very favorable.
