Abstract
The invention provides a horizontal flash tank for a centrifugal unit. The horizontal flash tank comprises a head, a shell body, a liquid inlet pipe, a liquid outlet, a liquid spraying liquid return opening and an oil cooling liquid return opening. The liquid inlet pipe and the head are welded deep in the inside of the flash tank, an end opening of the liquid inlet pipe is upward, the end portion of the liquid inlet pipe is drilled, and the end opening of the liquid inlet pipe is welded through a plug plate. The liquid spraying liquid return opening and the oil cooling liquid return opening are welded to the shell body, and an opening portion is provided with an impact-resistant baffle. A baffle, a certain distance from the impact-resistant baffle, is welded close to the right side of the impact-resistant baffle. The right side of the baffle is provided with a fixing gird plate and a first-level filtering screen which are welded to the shell body. An air absorbing baffle is arranged under an air outlet and welded to the shell body. A second-level filtering demisting screen assembly is arranged under the air absorbing baffle, two sides of the second-level filtering demisting screen assembly are provided with end plates, and the end plates and the second-level filtering demisting screen assembly are welded to the shell body. The horizontal flash tank can effectively lower noise and severe fluctuation of a liquid face generated after high-speed liquid refrigerants enters the flash tank, and eliminate the phenomenon that liquid exists in gas.
Description
Technical field
The invention belongs to mechanical manufacturing field, be specifically related to a kind of central air-conditioning centrifugal chiller internal structure.
Background technology
Along with Chinese national economy build continue, fast-developing, living standards of the people improve fast, the demand of the refrigeration air-conditioner of large standard ton is increasing, and centrifugal unit receives the favorable comment of numerous clients with its High cooling power, low noise, high energy efficiency and the feature such as reliable.
Flash tank is requisite parts in centrifugal unit, and the liquid refrigerant carrying out condenser enters flash tank through reducing pressure by regulating flow, and in flash tank, flash distillation becomes saturated gas, and the middle air entry that saturated gas enters compressor compresses; The liquid refrigerant formed in flash tank is supplied devaporation device.
The liquid refrigerant carrying out condenser in prior art directly enters flash tank after reducing pressure by regulating flow, causes the liquid level big ups and downs in flash tank, and with very large noise.
Because centrifuge does not allow absorbing gas belt liquid in pressure of inspiration(Pi) compression process, the gas so flashed in flash tank, does not just allow the generation of being with liquid phenomenon, if absorbing gas belt liquid when entering air entry in the middle of compressor, not only reduce the cold of unit, also major injury is caused to compressor.
Summary of the invention
The object of the present invention is to provide a kind of horizontal flash tank for centrifugal unit, to solve problem described above.
The present invention is primarily of end socket, housing, feed tube, liquid outlet, liquid spray liquid return hole, oil cooling liquid return hole composition, the technical scheme solving its problem is that feed tube welds with end socket and gos deep into that it is inner, feed tube port upward, hole, and port closure plate welds by feed tube end; Liquid spray liquid return hole and oil cooling liquid return hole and case weld, export department arranges erosion control baffle plate; Apart from erosion control baffle plate one segment distance, weld baffle plate on the right side; Stationary grid and single filter silk screen are set on the right side of baffle plate, stationary grid and single filter silk screen and case weld.
Boring area in feed tube end of the present invention is 2 ~ 3 times of feed tube area.
Liquid of the present invention spray liquid return hole and oil cooling liquid return hole can axially or circumferential and case weld.
Air-breathing baffle plate is set immediately below gas outlet of the present invention, air-breathing baffle plate and case weld.
Preferably, arrange cascade filtration demist silk screen assembly below described air-breathing baffle plate, cascade filtration demist silk screen assembly both sides arrange end plate, end plate and cascade filtration demist silk screen assembly and case weld.
The cold-producing medium of liquid state is divided into two parts by single filter silk screen, and the liquid fluctuating in left side is violent, and the liquid level on right side is relatively more steady, and make centrifugal unit operation more steady, Energy Efficiency Ratio is higher, reaches energy-efficient effect; After entering feed tube from the liquid refrigerant that condenser is next, the boring on feed tube effectively can reduce the noise of unit.
Adopt the present invention effectively can reduce noise; reduce the liquid level big ups and downs produced after high speed liquid refrigerant enters flash tank; eliminate the band liquid phenomenon in gas; improve the cold of unit; increase the Energy Efficiency Ratio of unit; and effectively can protect compressor, make that the operation of unit is more reliable, noise is lower.

In figure, 1 is end socket, and 2 is feed tube, and 3 is liquid spray liquid return hole, 4 is oil cooling liquid return hole, and 5 is erosion control baffle plate, and 6 is end plate, 7 is air-breathing baffle plate, and 8 is gas outlet, 9 cascade filtration demist silk screen assemblies, 10 is liquid outlet, 11 is housing, 12 single filter silk screens, and 13 is stationary grid, 14 is baffle plate, and 15 is closure plate.
Detailed description of the invention
Embodiment 1
As shown in Figure 1: feed tube 2 welds with end socket 1 and gos deep into its inside, and feed tube 2 is directed upwardly, and holes in feed tube 2 end, and boring area is 2 times of feed tube area, and port closure plate welds; Liquid spray liquid return hole 3 and oil cooling liquid return hole 4 circumference are welded with housing 11, and export department adds erosion control baffle plate 5; Apart from erosion control baffle plate 5 one segment distance, weld baffle plate 14 on the right side; Stationary grid 13 and fixing rear and housing 11 seal welding of single filter silk screen 12; Air-breathing baffle plate 7 and housing 11 are welded in immediately below gas outlet 8; End plate 6 and cascade filtration demist silk screen assembly 9 carry out seal welding with housing 11, and symmetry is arranged on below gas outlet 8, and liquid outlet 10 is in the below of housing 11, and gas outlet 8 is above housing 11; Feed tube 2, liquid spray liquid return hole 3, oil cooling liquid return hole 4 are arranged on the left of single filter silk screen 12, and gas outlet 8, liquid outlet 10 is arranged on the right side of single filter silk screen 12.
During use, the liquid refrigerant (containing a small amount of gas) carrying out condenser enters flash tank inside by feed tube assembly 2, through noise reduction, shunting, refrigerant strikes is at end socket 1, after housing 11 and baffle plate 14, change flow direction, fall under gravity to bottom flash tank; From liquid spray liquid return hole 3, the cold-producing medium of oil cooling liquid return hole 4, through erosion control baffle plate 5, also flows to bottom flash tank, and now on the left of single filter silk screen 12, liquid fluctuating is violent; Liquid refrigerant flows through single filter silk screen 12, and flow velocity reduces, and liquid level is steady, and the cascade filtration demist silk screen assembly 9 of flash gas through top filters out the drop carried secretly in gas, is entered the middle air entry of compressor, carry out tonifying Qi compression by gas outlet 8; The liquid of bottom feeds to evaporimeter by liquid outlet 10.
