Abstract

A kind of drainage system for being used to discharge on-condensible gas in condenser is the utility model is related to, the device is provided with Venturi tube below double-pipe condenser by connecting tube, and connecting tube is arranged on Venturi tube larynx section and contraction section intersection.When pouring in high velocity air in Venturi tube, using the vacuum suction effect of Venturi tube, the steam in the condenser with certain vacuum degree thoroughly can effectively be discharged clean.The device has the advantages of simple and compact for structure, energy-conserving and environment-protective, on-condensible gas discharge efficiency is high.

Description

The drainage system of on-condensible gas in a kind of discharge condenser
First, technical field
The utility model belongs to condenser equipment technical field, is related to and a kind of is used to discharge drawing for on-condensible gas in condenser Flow device.
2nd, background technology
Horizontal shell-and-tube cooler is one of main heat transmission equipment of industrial department, and it is mainly by cylindrical housing and horizontal tube Shu Zucheng, refrigerant vapour flow out in horizontal out-tubular condensing, condensate liquid from bottom of cylinder, and cooling water repeatedly comes and goes in horizontal tube Flowing.It is one of the major reason for declining condensation efficiency containing on-condensible gas in horizontal shell-and-tube cooler, in water vapour Containing 1% on-condensible gas surface coefficient of heat transfer can be made to reduce by 60%.Therefore, it is to improve condenser workability to exclude on-condensible gas The important key of energy.
At present, on-condensible gas floss hole is set up in on-condensible gas easily at accumulation, however, when condenser is in vacuum, The on-condensible gas that inside is gathered is difficult to row into environment.
3rd, utility model content
The purpose of this utility model is to provide a kind of drainage system for being used to discharge on-condensible gas in condenser, existing to solve The shortcomings that on-condensible gas effectively discharges in certain vacuum degree condenser can not will be had by opening up on-condensible gas floss hole.
The utility model can be achieved through the following technical solutions:A kind of drainage for being used to discharge on-condensible gas in condenser Device, it is characterised in that the inside including sleeve pipe 4 is provided with condenser pipe 3, and the left side of condenser pipe 3 is provided with outlet pipe 1 and water outlet Valve 2;Water intaking valve 7, water inlet pipe 8 and circulating pump 9 are sequentially installed with the right side of condenser pipe 3;Steam is installed on the top of sleeve pipe 4 Pipe 5 and steam valve 6.
The lower section of described sleeve pipe 4 is provided with drainage tube 12, and the pipe is connected to the contraction section and larynx section of Venturi tube 14 Junction, and Venturi tube 14 is arranged in connecting tube 15.
The import of described connecting tube 15 is provided with air pump 16.
Thermometer 10 and air bleeding valve 11 are installed on the outlet section of described connecting tube 15.
Drain valve 13 is installed on described drainage tube 12.
The beneficial effects of the utility model are:The device is provided with one end by connecting tube below double-pipe condenser, Venturi tube larynx section and contraction section intersection are arranged in the other end of connecting tube.When pouring in high velocity air in Venturi tube, Using the vacuum suction effect of Venturi tube, the steam in the condenser with certain vacuum degree thoroughly can effectively be discharged dry Only.The device has the advantages of simple and compact for structure, energy-conserving and environment-protective, on-condensible gas discharge efficiency is high.
4th, illustrate
Fig. 1:It is overall structure diagram of the present utility model.
In figure:1. outlet pipe, 2. outlet valves, 3. condenser pipes, 4. sleeve pipes, 5. steam pipes, 6. steam valves, 7. water intaking valves, 8. Water inlet pipe, 9. circulating pumps, 10. thermometers, 11. air bleeding valves, 12. drainage tubes, 13. drain valves, 14. Venturi tubes, 15. connections Pipe, 16. air pumps, 17. vacuum meters.
Embodiment
The utility model embodiment is elaborated below in conjunction with the accompanying drawings.
Condenser pipe 3 is installed in the inside of sleeve pipe 4, outlet pipe 1 is installed in the left side of condenser pipe 3, is provided with the pipe Outlet valve 2;Water inlet pipe 8 and circulating pump 9 are sequentially installed with the right side of condenser pipe 3, water intaking valve 7 is installed on water inlet pipe 8. The top of sleeve pipe 4 is provided with steam pipe 5, and steam valve 6 is provided with the pipe.Drainage tube 12 is installed in the lower section of sleeve pipe 4, should Pipe is connected to the junction of the contraction section of Venturi tube 14 and throat, and Venturi tube 14 connects with connecting tube 15, and gas is housed on the pipe Pump 16, air bleeding valve 11 is installed on thermometer 10.Drain valve 13 is installed on drainage tube 12.It is provided with sleeve pipe 4 true Empty table 17.
A kind of drainage system for being used to discharge on-condensible gas in condenser, at work:Carry the steam of on-condensible gas The ring-type condensation space of sleeve pipe 4 and the composition of condenser pipe 3 is entered from steam pipe 5.Cooling water is under the driving of circulating pump 9 from entering Water pipe 8 is flowed into condenser pipe 3 and left from outlet pipe 1.Because condenser pipe wall surface temperature is less than the saturation temperature of steam, steam is cold Solidifying, on-condensible gas is accumulated in condensation space.When the vacuum meter 17 on sleeve pipe 4 exceedes set-point, drain valve 13 is opened.Do not coagulate Gas is flowed into Venturi tube 14 from drainage tube 12 first.Contraction section and larynx section intersection when fluid flow path Venturi tube 14 When, flow velocity increase, pressure declines, and produces vacuum suction, the on-condensible gas in the downstream of sleeve pipe 4 is flowed through the heel row of connecting tube 15 to environment In.
