The present utility model will be described in detail below with reference to the accompanying drawings and examples.
The utility model provides a multi-channel Venturi compressed air gas-liquid separation core, as shown in figures 1-4, comprising: a bottom cover 1 provided with a plurality of first Venturi through holes 11 for separating gas from liquid of compressed air, a connecting cover 2 provided with a plurality of second Venturi through holes 21 corresponding to the first Venturi through holes 11 one by one, and an upper cover 3 provided with T-shaped through holes 31; one end of the connecting cover 2 is fixedly connected with the bottom cover 1, and the other end of the connecting cover is fixedly connected with the bottom cover 1; one end of the second venturi through hole 21 is communicated with the first venturi through hole 11, and the other end is communicated with the T-shaped through hole 31.
In the embodiment, ten first venturi through holes 11 are arranged at intervals on the outer edge of the bottom cover 1, ten second venturi through holes 21 are arranged at intervals on the outer edge of the connecting cover 2, and the upper cover 3 is conical; each first venturi through hole 11 is correspondingly communicated with one second venturi through hole 21; ten second venturi through holes 21 are all communicated with the T-shaped through hole 31; the Venturi through hole is a through hole with a section similar to a Venturi tube, wherein the middle caliber is small, the end caliber is large, or one end caliber is small, and the other end caliber is large; the upper cover 3 and the bottom cover 1 are buckled on the connecting cover 2 through the matching of a bolt and a pin hole (or other modes, such as bonding by waterproof adhesive and buckling inside buckle).
The gas-liquid separation principle is as follows: compressed air with the pressure greater than 2KG enters the first Venturi through hole 11 from the end with the relatively large caliber, and gas-liquid separation occurs at the section (interface at B in FIG. 4) where the pore diameter is switched; the reason is that the flow speed and the pressure of the fluid at the small caliber are low, the compressed air can pass preferentially, the movement speed of the water and the oil is relatively low, most of the fluid stays at the large caliber, and the fluid is condensed to a certain amount to form an oil-water mixture which falls down from the first Venturi through hole 11; in the same way, the second venturi hole 21 is condensed with a certain amount of the oil-water mixture, and drops onto the first venturi hole 11. The compressed air subjected to the two-stage oil-water separation flows out through the T-shaped through hole 31.
The utility model utilizes the venturi tube principle to enable the compressed air to be subjected to gas-liquid separation in the venturi through holes, thereby eliminating the filter element and overcoming the defect that the prior compressed air oil-water separator needs to replace filter element consumables periodically. In addition, the compressed air gas-liquid separation core is divided into the bottom cover 1, the connecting cover 2 and the upper cover 3, so that the manufacturing cost is reduced by using an injection molding process, and the whole printing forming can be performed by using a 3D printing process without considering the cost.
Further, the first venturi through hole 11 includes: a first middle hole 111, a first lower end hole 112, a first upper end hole 113; one end of the first middle hole 111 is communicated with the first lower end hole 112, and the other end is communicated with the first upper end hole 113; the aperture of the first lower end hole 112 and the aperture of the first upper end hole 113 are larger than the aperture of the first middle hole 111.
Further, the second venturi through hole 21 includes: a second lower end hole 211, a second upper end hole 212; one end of the second lower end hole 211 is communicated with the first upper end hole 113, and the other end is communicated with the second upper end hole 212; the second lower end hole 211 has a larger aperture than the second upper end hole 212.
As shown in fig. 4, in the present embodiment, the radius of the first middle hole 111 is 0.6mm, and the radius of the first lower end hole 112 and the radius of the first upper end hole 113 are both 4mm. The length of the first middle hole 111 is 2.5mm, the length of the first lower end hole 112 is 6mm, and the length of the first upper end hole 113 is 1mm; the radius of the second lower end hole 211 is 4mm and the length is 3mm; the second upper end hole 212 has a radius of 0.6mm and a length of 4mm. The applicant finds that the pore size selection can achieve better gas-liquid separation effect in research and development.
Further, to enhance the gas-liquid separation effect, the hole axis of the first middle hole 111 is not collinear with the hole axis of the second upper hole 212, and is located on two sides, preferably symmetrical sides, of the hole axis of the first lower hole 112.
A separator comprises the multi-channel Venturi compressed air gas-liquid separation core.
Further, the method further comprises the following steps: a gas pipe connecting seat 4 provided with a compressed air inlet 41 and a compressed air outlet 42, an outer shell 5 for receiving compressed air led in by the compressed air inlet 41, and an inner shell 6 for fixing at least one multi-channel venturi compressed air gas-liquid separation core; the air pipe connecting seat 4 is detachably connected with the top end of the shell 5; the inner shell 6 is positioned inside the outer shell 5 and is detachably connected with the air pipe connecting seat 4; the T-shaped through hole 31 communicates with the compressed air outlet 42.
As shown in fig. 5, the top end of the outer shell 5 is in threaded connection with the air pipe connecting seat 4, and the top end of the inner shell 6 is also in threaded connection with the air pipe connecting seat 4; the compressed air intake port 41 communicates with the inside of the housing 5; the compressed air gas-liquid separation cores are connected and fixed on the inner shell 6 (as shown in fig. 6) end to end, namely, the bottom cover 1 in the compressed air gas-liquid separation core positioned on the upper layer is sleeved and fixed on the upper cover 3 in the compressed air gas-liquid separation core positioned on the lower layer, and the inner shell 6 is sleeved and arranged on the bottom cover 1 or the connecting cover 2 in the compressed air gas-liquid separation core positioned on the uppermost layer. The air paths of the compressed air gas-liquid separation cores on the inner shell 6 are connected in parallel, the first Venturi through holes 11 in the bottom cover 1 are directly communicated with the inside of the outer shell 5, and the T-shaped through holes 31 in the upper cover 3 are directly communicated with the compressed air outlet 42; the greater the number of compressed air gas-liquid separation cores, the greater the flow rate of compressed air flowing into the T-shaped through holes 31.
Further, in order to facilitate installation of the inner casing 6 and the plurality of compressed air gas-liquid separation cores, a screw cap 51 is screwed at the bottom end of the outer casing 5; in order to facilitate the discharge of the separated oil-water mixture out of the housing 5, the screw cap 51 is provided with a drain hole 511, and regular draining as required can be achieved by installing a conventional drain valve (not shown in the drawings) on the drain hole 511.
