Description
Technical Field
The invention relates to a sealing system of a fan. And more particularly to a system for shutting off leakage of fan gas material using a wet seal with barrier liquid.
Background
As shown in fig. 1 and 2, the material in the fan housing 2 is high-pressure gas 5, and the outside of the housing 2 is low-pressure air 6, so that a rotating shaft 1 rotating at a high speed is led from the outside of the housing 2 to the inside of the housing 2 for power input. In order to reduce leakage, a plurality of floating graphite ring parts 4 are arranged on the rotating shaft, so that a comb-shaped labyrinth passage is formed by the leakage passage between the static shell 2 and the rotating shaft 1, the original leakage passage is narrowed and lengthened, and the leakage resistance is increased. At the same time, a continuous, clean, pressure-stable nitrogen 7, slightly above the pressure of the material 5, is introduced at the inlet of the housing 2. The main component of the gas thus leaked into the atmosphere is nitrogen 7 instead of the material gas 5, and this sealing system is called a gas seal.
The structure and the working principle of the labyrinth air seal system with the comb teeth shape formed in the fan in the prior art have a plurality of problems which are difficult to overcome:
1. the leakage path is also a path where the high voltage end is shorted to the low voltage end.
2. In the channel between the rotating shaft and the static shell in the high-speed rotating process, not only material gas but also nitrogen gas exist, and because the rotating speed of the rotating shaft is high, the air pressure distribution in the channel cannot be stable, turbulence, surge flow, turbulence, vortex and even reflux are necessarily formed, so that the gas becomes mixed gas of the material gas and the nitrogen gas, and the mixed gas is not pure nitrogen gas leaked into the atmosphere. In reality, because the material gas contains various VOCs, sulfides and even heavy metals, the place which is not far away from the fan can smell the foul smell.
3. The continuous, clean and stable nitrogen with the pressure slightly higher than the material pressure must be introduced, so that the energy waste and the resource waste are necessarily caused.
4. The material gas leaks into the atmosphere to pollute the environment and increase haze.
5. The material itself is a resource, and leakage causes waste.
6. In the process of purifying the gas, only a part of the material gas runs away, the part of the material gas cannot be purified, and the purity index of the purified material gas cannot be finished. For example: it is impossible to achieve a purity of 99.9% or 99.99% of the total amount of the process feed gas because the leaked portion of the feed gas has never been subjected to the purification process.
7. The nitrogen which is continuous, clean, stable in pressure and slightly higher than the pressure of the materials is introduced when the machine is stopped, and otherwise material residues still exist in the machine set under the stop state, so that energy waste and resource waste are necessarily caused.
8. In case of failure of the nitrogen source or sudden pressure reducing the likelihood of contaminating the entire nitrogen source line.
