Common sense of soda-water mixing
1. The mixing of steam and water is a kind of surface contact heat transfer, and the water on the contact surface vaporizes and expands instantly, that is, it explodes locally, which always produces noise. The same is true if water drops fall into a boiling oil pan, they will explode and splash.
2. When steam and water are mixed, the larger the heat exchange surface, the better (the larger the heat exchange surface, the smaller the explosive force per unit area and the smaller the noise), such as fine sand scattered on the water surface.
3, soda mixing, the lower the static pressure, the better (the faster the flow rate, the higher the dynamic pressure, the lower the static pressure, the better the buffering effect, the less noise), such as cotton batting.
Immersed steam-water mixing heater structure
1. The submerged steam-water mixing heater consists of a shell and a core. Large and small holes are distributed up and down in the shell, and small inclined holes are distributed around the core. There is an effective mixing heating zone between the shell and the core.
2. When the submerged steam-water mixing heater works, steam is injected into the heating area of the mixer from the small inclined hole of the core at high speed, which pushes the water in the heating area to rotate at high speed and completes the heat transfer of steam-water mixing at the same time. At the same time, the heated water is continuously discharged from the upper hole of the shell when the upper part rotates, and the lower hole is replenished to heat the water circulation in the water tank. Like a tornado.
3. The submerged steam-water mixing heater seems to be simple in structure, but it is not easy to do it well. For example, car tires, good tires are just different.
4. The submerged steam-water mixing heater has strict technical requirements in production, which is also the core technology of this product.
5. The core component of the submerged steam-water mixing heater is the core, and the angle of the steam inclined hole and the structure of the heating zone are the key points, which comprehensively affect the use effects such as noise, vibration and circulation.
Noise and vibration of submerged steam-water mixing heater
1. The submerged soda-water mixer is a utility model patent certificate product designed and invented by Mr. Simon Fan in 1989 (patent number: 89 211610.2). Steam and water are directly mixed for heating, without noise and vibration, and the thermal efficiency is 100%.
2. Immersed steam-water mixing heater, steam and water are directly mixed, and heat exchange is completed instantly.
3. Immersed steam-water mixing heater, in the normal working process, steam and water mix and exchange heat at high speed and in a large area, without noise and vibration, only the sound of steam flowing (used upstairs, but without influence downstairs).
4. Immersed steam-water mixing heater, with steam working pressure of 0. 1-0.2MPa is the most suitable.
5. In addition to the noise and vibration produced by products in informal factories, abnormal use of heaters will also produce noise and vibration.
6. The steam pressure is too low to drive the water in the heating area to rotate at high speed, which affects the use effect.
7, if the steam pressure is too high, so that cold water can't enter the heating area, steam directly into the water tank, contact with the surface of cold water mixed heat transfer, it will produce noise and vibration.
8. If the water flows back to the steam area, it will impact the pipeline system, that is, vibration. As we often say, water hammer.
Constructing an efficient submerged steam-water mixed heater system
1, submerged steam-water mixing heater, due to structural limitations, has strong adaptability in flow, heating capacity and adjustment capacity.
2. First, the number of heaters is equipped according to the shape of the water tank.
3, and then according to the steam pressure, temperature, water tank size, heating time requirements, etc. , calculate the heater specification and steam pipe size.
4. Ximen hot water machinery, the originator of alkali precipitation mixer, has been specializing in the production of SEMEM_HJ alkali precipitation mixer for 23 years.
