Features of the use of centrifugal separators OPEKS-1-SC16
Many enterprises in the light, heavy, chemical, etc. industries use water vapor and compressed air in their technology. The widespread use of these environments is due to the following characteristics:
- General availability (air and water are the most popular substances on our planet);
- High efficiency of converting the potential energy of compressed gas into mechanical work (pneumatic equipment, turbines ...);
- Dry steam is an incredibly good heat carrier.
As we have already seen, equipment operating on compressed air or water vapor is used in all branches of industry. The efficient and safe operation of such equipment is based on the presence of a clean product without any foreign matter or moisture droplets. This is due to the fact that the potential for using air and steam directly depends on their pressure. Accordingly, movement through pipelines is associated with high flow rates. If there are inclusions (moisture droplets) in the product, they will hit the pipe walls and equipment surfaces at high speed. Moisture also provokes corrosive reactions. This situation will ultimately lead to the decommissioning of equipment and, accordingly, the entire enterprise. The problem of cleaning from solids can be solved by installing a mechanical filter. With water droplets, things are a little more complicated, since high pressure water cuts the steel.
To begin a comprehensive study of the problem, we will analyze the nature of the appearance of moisture drops:
- Air initially has a certain amount of moisture, since it is taken from the environment or premises.
- Also, in the process of movement, the process of condensation constantly occurs.
Steam from the boiler room initially comes with a dryness coefficient X = 1, but moving along long and, often poorly insulated pipes, condenses into drops of moisture.
To help in solving the problem of dehumidification of air or steam comes a fairly simple and reliable equipment manufactured on the territory of the production complex of LLC NPP OPEKS ENERGOSYSTEMY - a centrifugal steam separator OPEKS-1-SC16. A whole line of separators has been developed from DN15 to DN300, nominal pressure PN16 / 25, working medium temperature from -10 ° C to 300 ° C. Let's take a closer look at the design of the separator:
F - threaded connection for condensate drainage.
K - connection, which is located in the upper part of the separator, for the installation of an air vent valve.
The body is made of carbon steel or stainless steel, all internal elements (spiral swirler of the gas flow) are made of stainless steel, which significantly increases the service life of the equipment. It is imperative to select the size of the separator the same as the diameter of the steam line to avoid local resistances. If everything is selected correctly, then the pressure loss on the separator is neglected. Recommended optimal values of steam velocity should be in the range of 20 - 40 m / s, minimum - 15 m / s.
Let us consider step by step the operation of the separator
The inlet pipe is used to get the steam-water mixture or compressed air into the separator. The pair is executed in such a way that the flow would be fed tangentially, and as a result, centrifugal forces were created and the effect of rotation occurred. Such a twisting of the flow in a spiral with the help of a baffle promotes the separation of particles with a large specific gravity (moisture, mechanical impurities ...). The separated condensate is discharged through the provided drain hole at the bottom of the separator with an external thread cut on it. The condensate must be redirected to the condensate pipe using a Japanese brand Yoshitake thermodynamic steam trap type TD-10NA. Thus, the dried steam moves to the outlet and is further directed to the steam line behind the separator. An automatic air vent is located on the upper connection. It is recommended to install separators as close to the consumer as possible, for example, before flow meters (Khrone, Bopp & Reuther), control valves (Yoshitake), plate heat exchangers (THERMAKS), shell-and-tube heat exchangers (OPEKS-2). With the right system, the life of the separator will usually exceed the life of the piping.

Thus, when installing the OPEKS-1-SC16 separator, we exclude the possibility of erosion and corrosive destruction of pipelines and at the same time increase the efficiency and service life of equipment that uses steam or compressed air. After all, industrial equipment is a key element of any enterprise and efficient, and most importantly, safe operation of such equipment is the key to the development and trouble-free operation of the entire enterprise.
