The working process and working principle of the invention are as follows:
When the gas-liquid separator is used, firstly, ammonia solution enters from the liquid inlet pipe 11, the solution with little or no gas enters into the filter screen assembly 7 of the inner pipe 5 directly through the grids on the protective screen 4 on the inner pipe 5, and the solution is filtered by the filter screen assembly 7 and is directly pumped out from the liquid outlet pipe 12 by the solution pump in the unit. The other part of ammonia solution with high gas content is subjected to first-stage gas-liquid separation by utilizing the centrifugal force of the solution which rapidly impacts the shell 3, a small amount of gas is removed, the gas is directly discharged from the gas outlet on the shell 3, then the ammonia solution subjected to the first-stage gas-liquid separation is subjected to second-stage gas-liquid separation by vibrating the filler 6, the solution separated by the filler 6 enters the inner pipe 5 through a plurality of through holes 10 on the pipe wall of the inner pipe 5, the solution enters the inner pipe 5 and then impacts the pipe wall of the inner pipe 5 to perform third-stage gas-liquid separation, the gas can be discharged through grids on the protective net 4 on the inner pipe 5, then the gas is directly discharged through the gas outlet on the shell 3, and the solution subjected to the 3-stage gas-liquid separation is filtered by the filter screen assembly 7 and is discharged from the liquid outlet pipe 12, and is directly pumped by the solution pump in the unit. The solution pumped by the solution pump is completely liquid or gas content is greatly reduced through the 3-stage gas-liquid separation, so that better working conditions are created for the pumping of the solution pump, the pumping capacity of the solution pump is improved, and the solution of the unit is better circulated.
The first-stage gas-liquid separation and the third-stage gas-liquid separation are both centrifugal separation, and when the gas and the liquid are mixed and impact the outer shell or the inner tube, the rotation flow can occur, and the centrifugal force of the liquid is larger than that of the gas, so that the liquid has the centrifugal separation tendency, and the liquid is adhered to the wall of the outer shell or the inner tube and is gathered together under the action of gravity.
Second stage gas-liquid separation, which is a filler separation, wherein when gas and liquid are mixed together and flow, if the gas and the liquid meet the filler, the gas is baffled and moves away, the liquid continues to have a forward speed due to inertia, and the forward liquid adheres to the surface of the filler and is gathered downwards due to gravity.
The foregoing is merely a preferred embodiment of the present invention, and it should be noted that modifications and substitutions can be made by those skilled in the art without departing from the technical principles of the present invention, and these modifications and substitutions should also be considered as being within the scope of the present invention.
