Description

The automatic big flow centrifugal atomizing of air pressing type sprinkler head

The utility model relates to the big flow centrifugal atomizing of a kind of automatic air pressing type sprinkler head, belongs to recirculated water cooling technical field.

A kind of centrifugal atomizing sprinkler head that is used in cooling circulating water in the circulating water cooling system is arranged in the background technology, mainly by centrifugal chamber, nozzle, water inlet pipe and installing plate are formed, and centrifugal chamber is the spheroidal jar, nozzle is positioned at the center of centrifugal chamber end face, water inlet pipe is connected with centrifugal chamber with tangential way, nozzle, and water inlet pipe is communicated with the centrifugal chamber inner chamber, installing plate is fixed on the other end of water inlet pipe, and bolt hole is arranged on the installing plate.Two or more centrifugal atomizing sprinkler heads are installed on the rotatable parts of upright feed pipe with circumference uniform distribution and the square obliquely mode of nozzle.When low-pressure recirculated water when feed pipe, rotatable parts and each water inlet pipe flow into each centrifugal chamber, water can just eject obliquely from each nozzle.The reaction force of injection water orders about the opposite spin of centrifugal chamber towards the injection water direction of motion.Injection water and windage, the latter tears into microgranular water to the former, forms mist flow.Though the described centrifugal atomizing sprinkler head of background technology can atomize, atomization quantity is little, and atomized particles is few, and the surface area summation of particulate is also little, and just the total surface area with the air mass-and heat-transfer is little, so recirculated water cooling weak effect.

It is big that the purpose of this utility model provides a kind of flow, the big flow centrifugal atomizing of the automatic air pressing type sprinkler head that nebulization efficiency is high.This purpose realizes by adopting following technical proposal: the edge of jet expansion adopts thin sword structure, is provided with deflection cone and deflection cone in the centrifugal chamber and has the water conservancy diversion taper hole.

Fig. 1 is a structural representation of the present utility model, and wherein 1 is nozzle, the 11st, and jet expansion, the 12nd, the nozzle venturi, the 13rd, nozzle entrance, α are the nozzle subtended angles, the 2nd, centrifugal chamber, the 3rd, deflection cone, the outlet of 31 deflection cones, the 32nd, water conservancy diversion taper hole, 33 deflection cones inlet, β is the deflection cone subtended angle, the 4th, and water inlet pipe, the 5th, installing plate.

Now be described with reference to the accompanying drawings structure of the present utility model and operation principle.

The big flow centrifugal atomizing of a kind of automatic air pressing type sprinkler head, by nozzle 1, centrifugal chamber 2, compositions such as water inlet pipe 4 and installing plate 5, nozzle 1 contains jet expansion 11, nozzle venturi 12 and nozzle entrance 13, centrifugal chamber 2 is cylindrical tanks, nozzle 1 is integrated at the center and centrifugal chamber 2 end faces of centrifugal chamber 2 end faces, one end of water inlet pipe 4 is connected with centrifugal chamber 2 in the tangent mode of water inlet pipe 4 and centrifugal chamber 2 cylinders, nozzle 1, centrifugal chamber 2 and water inlet pipe 4 inner chambers communicate, the other end of water inlet pipe 4 and installing plate 5 are fixed together, on the installing plate 5 bolt hole is arranged, it is characterized in that, be provided with deflection cone 3 in the centrifugal chamber 2, deflection cone 3 contains deflection cone outlet 31, water conservancy diversion taper hole 32 and deflection cone inlet 33, and deflection cone 3 is integrated by deflection cone inlet 33 center and centrifugal chambers 2 in centrifugal chamber 2 bottom surfaces, water conservancy diversion taper hole 32 is tapered, little bottom, top is big, and the top and the bottom of water conservancy diversion taper hole 32 are communicated with centrifugal chamber 2 and atmosphere respectively, and the edge of jet expansion 11 is thin sword structure, the diameter of nozzle venturi 12 is 5～30mm, the diameter of deflection cone outlet 31 is 2～10mm, and nozzle subtended angle α is 15 °～120 °, and deflection cone subtended angle β is 15 °～90 °.

Operation principle.When the utility model is used for circulating water cooling system, by the bolt hole on bolt and the installing plate 5, two or more the utility model, promptly the big flow centrifugal atomizing of air pressing type sprinkler head is installed on the rotatable parts of upright feed pipe with circumference uniform distribution and the square obliquely mode of nozzle 1 automatically.When low-pressure recirculated water through feed pipe, rotatable parts and each water inlet pipe 4, when flowing into each centrifugal chamber 2 with tangential direction, the outer wall spiral of current edge deflection cone 3 separately rises, eddy flow water through separately nozzle entrance 13 to separately nozzle venturi 12, by the square obliquely mist flow that ejects of jet expansion 11 separately, under the reaction force of mist flow drove, each centrifugal chamber 2 was towards the opposite spin of the mist flow direction of motion again.At this moment air is squeezed into deflection cone inlet 33 automatically, through the top that separately water conservancy diversion taper hole 32 and deflection cone outlet 31 enter into centrifugal chamber 2 separately.On the top of separately centrifugal chamber 2, the eddy flow water of rotation temporarily mixes with air at a high speed.During the nozzle venturi 12 of the eddy flow water that is mixed with air by separately, flow velocity is the highest, and rises with the spiral inner wall of moisture film form along separately nozzle 1, and the tangential direction of last jet expansion 11 along separately ejects, and forms mist flow.

Compare with background technology, the utility model has following advantage:

1. eddy flow water ends to spurting into atmosphere from entering nozzle venturi 12, and stand atomization process altogether three times: when forming moisture film, gas-liquid separation causes water break; The thin bladed edge of jet expansion 11 impels moisture film and air strong friction; The bulky grain water droplet of spurting in the mist flow of atmosphere continues and windage.Each above-listed process all can form a large amount of microgranular water, i.e. atomized water.In other words, it is many that the utility model forms atomized water, the nebulization efficiency height, and atomizing effect is good.

2. the mist flow flow that sprays of jet expansion 11 is big, and atomized particles is many, has greatly increased the total surface area with the air mass-and heat-transfer, so the recirculated water cooling is effective.

3. simple in structure, make easily, be convenient to safeguard that energy consumption is low during work that noise is little.

The utility model is particularly suitable for being used as the centrifugal atomizing sprinkler head in industrial and civilian circulating water cooling system.
