The Selection of Cleaning Agents The current choice of cleaning agents includes acid cleaning, which encompasses both organic acids and inorganic acids.

Organic acids mainly include oxalic acid, formic acid, etc.

Inorganic acids primarily include hydrochloric acid, etc. The heat exchanger is made of nickel-titanium alloy, and hydrochloric acid is used as the cleaning fluid. It can cause strong corrosion on the plates, shortening the service life of the heat exchanger. The most commonly used cleaning agent is 0.2% to 0.3% of melamine, along with 0.015% to 0.2% and 0.005% to 0.1% of ammonium sulfonate. Equipment cleaned and flushed thoroughly can self-passivate in the air. Condenser cleaning

Through repeated testing, it has been found that formic acid is an excellent choice for cleaning solutions. By adding buffering agents and surfactants to the formic acid cleaning solution, the cleaning effect is enhanced, and the corrosion of the solution on the plates is reduced. Chemical testing of scale samples has shown that formic acid can effectively remove scale that adheres to the plates, while it has a reduced corrosive effect on the heat exchanger plates.

The Basic Principle of Limescale Removal: Acid solutions react readily with calcium, magnesium, and carbonate scale, forming easily soluble compounds that dissolve the scale. Stripping Action: Acid solutions can dissolve oxides on metal surfaces, breaking the bond with the scale, thereby stripping and detaching the scale adhered to the metal oxide surface. Gas Ejection Action: After the acid solution reacts with carbonate scale, it produces a large amount of CO2. The CO2 gas, as it is released, exerts a certain lifting force on the scale layer that is less soluble or dissolves slowly, causing the scale to detach from the heat exchanger surface.

Do not clean stainless steel sheet with water containing 300×10^-6 chlorine.

Do not clean titanium plates with phosphoric or sulfuric acid.

3. Under normal circumstances, the concentration of the cleaning fluid should be below 4% (except for exceptions), and the temperature of the cleaning fluid should not exceed 60℃. Cleaning of the condenser

Clean spiral plate heat exchangers should be followed by the following steps.

Drain the liquid from both sides of the heat exchanger's inlet and outlet pipes. If it cannot be drained, use water to forcibly flush out the process liquid.

2. Flush both sides of the heat exchanger with approximately 43℃ warm water until the water draining out is clear and free of process fluid.

3. Drain the rinse water from the heat exchanger and connect to the on-site cleaning pump.

4. To clean a spiral plate heat exchanger, the condenser cleaning price must be properly flushed from bottom to top of the plates, ensuring all surfaces are wetted by the cleaning solution. Condenser cleaning

In most cases, plate heat exchangers can be cleaned without disassembly. Simply flush with water in the opposite direction to the medium flow to remove debris, but the pressure must not exceed the working pressure. Dongguan condenser cleaning is also possible using non-corrosive chemical cleaning agents for stainless steel. Over time, the plates of a plate heat exchanger may accumulate deposits, affecting heat exchange efficiency, so regular disassembly and cleaning are necessary. During cleaning, disassemble the plate heat exchanger, scrub the plate surfaces with a bristle brush, or use a non-corrosive chemical cleaning agent. Be cautious not to use a metal brush to avoid damaging the plates and compromising their corrosion resistance. Condenser cleaning

Scale buildup without cleaning damage

Scaling significantly reduces the heat exchanger efficiency of machine equipment, leading to a substantial increase in energy consumption and production costs.

(2) Scale buildup can degrade the thermal conductivity of equipment, leading to over-temperature and overheating of heat transfer surfaces in chemical plant condensers, which can cause safety hazards such as blisters, cracks, and explosions.

(3) Scale buildup can lead to under-deposit erosion, causing equipment breaches and leaks, reducing facility lifespan. It can destabilize the production process, compromise product quality, and trigger safety incidents. Condenser Cleaning

Organic Chemical Cleaning

Organic chemical cleaning utilizes organic cleaning agents to induce a chemical reaction, which dissolves, removes, or detaches dirt and other deposits from the heat exchange tube surface of heat exchangers. This method does not require disassembling the heat exchanger, simplifying the cleaning process and reducing the level of labor involved. However, its drawback is that if the organic cleaning agent is not selected properly, it can erode and damage the base material of the item being cleaned, leading to damage.

Recirculate: Force the cleaning fluid to circulate through the system using a pump to initiate cleaning.

Dipping method: Fill the machine with cleaning fluid and let it stand for a certain period.

Surge protector method: Fill the machine equipment with cleaning fluid, then, after a certain period, pump a portion of the cleaning fluid from the bottom through the column. Reintroduce the discharged liquid back into the machine equipment to achieve the purpose of mixed cleaning.
