High-pressure hot water cleaning machine: the "cleaning specialist" in the petroleum and chemical industry, ensuring smooth production
The hot water high-pressure cleaning machine uses a high temperature of 80-140℃ and a high pressure of 200-300bar to quickly break down tar deposits, oil sludge, and wax in petrochemical equipment, thereby improving the heat transfer efficiency of reaction vessels by 30% and the pipeline transportation capacity by 20%, reducing downtime for maintenance by 15 times per year, and making stubborn stains unable to hide.
The production environment in the petrochemical industry is complex, and the surfaces of equipment, the inner walls of pipelines, reactors, and storage tanks are often covered with stubborn stains such as crude oil, heavy oil, wax, and tar, which not only affect the heat dissipation and operational efficiency of the equipment but may also cause safety hazards due to high temperatures; traditional cleaning methods are unable to thoroughly remove these stains. The hot water high-pressure cleaning machine utilizes the dual effects of "high temperature softening" and "high pressure peeling" to precisely address the various cleaning challenges in the petrochemical industry, thereby providing strong support for the stable operation of production equipment.
Cleaning reaction vessels and storage tanks: breaking down stubborn stains to restore their functionality.
Reactor vessels are the core equipment in petrochemical production, and their inner walls are often covered with sticky polymers and carbonaceous deposits left over from material reactions; when crude oil and refined oil are stored in tanks, oil sludge and wax-like impurities tend to accumulate at the bottom. These impurities are hard and firmly adhere to the inner walls of the containers, making manual cleaning extremely difficult. A hot water high-pressure cleaning machine can raise the water temperature to 80-120°C, which can quickly soften the carbonaceous deposits on the reactor vessel's inner wall, turning them from a hard state into a porous structure. Coupled with 200-300 bar high-pressure water jets that rotate and scour along the vessel's walls, the carbonaceous deposits can be peeled off and removed layer by layer. As for the oil sludge at the bottom of the tank, the high-temperature water can emulsify the oil components within, and the high-pressure water jets can disperse the oil sludge into smaller particles, allowing them to be carried away by the water flow. This prevents the oil sludge from accumulating and reducing the tank's effective storage capacity. After cleaning, the heat transfer efficiency of the reactor vessel improves, and the storage capacity of the tank is restored, thereby minimizing production disruptions caused by accumulated impurities.
Oil pipeline evacuation: removal of fouling and blockage to ensure medium delivery
When oil pipelines convey crude oil and heavy oil for a long time, the inner walls will gradually form wax crust and oil pollution adherence layer, causing the diameter of the pipeline to shrink, the transmission resistance to increase, and even causing blockage.The hot water high-pressure washer is equipped with flexible high pressure hose and rotating nozzle, which can clean the inside of the pipe. The high temperature hot water (100-140 °C) can dissolve the waxy scale and make it fall off from the inner wall of the pipe.For the oil pollution adherence layer, high temperature can destroy the adhesion force of the oil, and high pressure water will wash it clean. For pipes of different diameters, the water pressure and the jet speed can be adjusted to ensure that there are no dead spots of cleaning. For example, after the high pressure cleaning of the heavy oil pipeline in the refinery, the resistance in the pipeline is reduced, the operation load of the oil pump is reduced and the transmission efficiency is improved, thereby avoiding the shutdown and overhaul caused by the pipeline blockage.
Heat exchanger and cooler cleaning: remove dirt from the heat exchanger surface and improve heat exchange efficiency
Heat exchangers and coolers are key equipment for heat exchange in petrochemical production, and the walls of the heat exchange pipe are easily formed by water quality problems, or by oil and impurities attached to the medium pollution, leading to a decrease in heat exchange efficiency and increased energy consumption. Hot water high-pressure cleaning machine can targetly clean the heat exchange surface: For dirt, high-temperature hot water can accelerate the dissolution of calcium carbonate and magnesium in the dirt, and high-pressure water will flush it from the inner wall of the heat exchange pipe. For oil and impurities, after the oil is emulsified at high temperature, the high pressure water flow completely removes it. Cleaner heat exchangers and coolers significantly improve heat exchange efficiency, reduce energy consumption, and reduce the risk of equipment overheating due to poor heat exchange.
Cleaning pumps and valves: removing dirt and grime from both surfaces and interiors to ensure smooth operation of equipment.
After long-term operation, the surfaces of pump equipment (such as centrifugal pumps and gear pumps) and valves in the petrochemical industry may accumulate oil stains and dust, and the internal components like impeller and valve disc might get stuck due to impurities, which could affect their normal operation. A high-pressure hot water cleaning machine can effectively wash a large area of the pump body, dissolve the oil stains at high temperatures, and use high-pressure water jets to thoroughly clean them; for the internal parts of the impeller and valves, a slender nozzle can be used to reach these areas, and high-pressure water jets can then be employed to remove impurities and oil stains, ensuring that the impeller can rotate smoothly and the valves can open and close properly. After cleaning, the pump equipment and valves will run stably, with a reduced failure rate, thereby extending the maintenance cycle of the equipment.
Cleaning the factory floor and equipment foundations: removing oil stains and grime to improve the working environment.
In petroleum and chemical plant areas, the ground and equipment foundations are often covered with extensive oil stains resulting from material leaks and spills, which, when mixed with dust, form hard oil sludge layers that not only degrade the cleanliness of the working environment but also pose risks such as slipping and fires. The fan-shaped nozzles of hot water high-pressure cleaning machines can effectively wash large areas of the ground, while high-temperature hot water emulsifies grease, and high-pressure water jets wash away the oil sludge and dust into drainage ditches, preventing the accumulation of long-term oil stains. For oil stains on equipment foundations, high-temperature hot water can penetrate the sludge layer, loosen it, and then be washed away by high-pressure water jets, restoring the foundation surface to a clean state. After cleaning, the overall environment of the plant improves, safety hazards are reduced, and a safer working environment is provided for employees.
The application of hot water high-pressure cleaning machines in the petroleum and chemical industry covers various scenarios such as reaction equipment, transportation pipelines, heat exchange equipment, pumps, valves, and plant environment, effectively removing stubborn stains to not only improve equipment operation efficiency and reduce energy consumption but also ensure production safety and minimize the risk of equipment failures and plant shutdowns, making it the ideal choice for cleaning and maintenance in the petroleum and chemical industry.
