Abstract
The utility model provides a boiler deaerator, comprising a deaerator body, wherein a water feeding pipe and a water discharging pipe are respectively arranged at the upper part and the lower part of the deaerator body; an oxygen discharging pipe with a check valve and a drain pipe are arranged at the top part and the bottom part of the deaerator respectively; a diffusion pipe is further arranged at the top part of the deaerator and an instrument is further arranged at the top part of the deaerator. With the adoption of the technical scheme, the boiler deaerator has the following advantages that: a set of diffusion pipe is additionally arranged at the top part of the deaerator; when the water pressure in the deaerator body is higher than a saturated pressure, a valve on the diffusion pipe is opened to reduce the pressure, so that the pressure and the temperature in the deaerator body are just at saturated conditions and oxygen is completely removed. Therefore, a subsequent water pump cavitation phenomenon is avoided.
Description
Technical field
The utility model relates to a kind of oxygen-eliminating device.
Background technology
Dissolved oxygen can cause the oxide etch of boiler and relevant device in the boiler feedwater; In order to prevent the generation of this phenomenon; Adopt at present mostly oxygen-eliminating device, i.e. oxygen-eliminating device body sealing vacuumizes or heats and makes reason go into the intrinsic water of oxygen-eliminating device to reach boiling point; Oxygen is overflowed from water, thereby reaches the purpose of deoxygenation.If but boiler feed temperature or pressure transient make the feed pressure above bubble point pressure, deoxygenation is incomplete, from the water that outlet pipe comes out, also contains a certain amount of oxygen, thereby makes water pump operation produce cavitation phenomenons.
Summary of the invention
The purpose of the utility model is to overcome above-mentioned deficiency a kind of boiler feed is provided.
The purpose of the utility model realizes through following technical scheme:
A kind of boiler feed; Comprise the oxygen-eliminating device body; In oxygen-eliminating device upper part of body and bottom water inlet pipe and outlet pipe are set respectively, oxygen output pipe and blow-off pipe in that the top and the bottom of oxygen-eliminating device are respectively arranged with the band check-valves also are provided with exhaust stack at the top of oxygen-eliminating device.
Above-mentioned boiler feed also is provided with instrument at the top of oxygen-eliminating device.
Adopt technique scheme; The utility model has following advantage: overlap exhaust stack owing to added one at the oxygen-eliminating device top; When the intrinsic hydraulic pressure above bubble point pressure of oxygen-eliminating device, open the valve on the exhaust stack, reduce pressure; Make and remove the intrinsic pressure and temperature of oxygen just in saturation state, deoxygenation is complete.Thereby stopped the generation of follow-up pump cavitation phenomenon.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
A kind of boiler feed as shown in Figure 1; Comprise oxygen-eliminating device body 4; Water inlet pipe 1 and outlet pipe 5 are set respectively in the upper and lower of oxygen-eliminating device body 4, and oxygen output pipe 2 and blow-off pipe 6 in that the top and the bottom of oxygen-eliminating device are respectively arranged with the band check-valves also are provided with exhaust stack 3 at the top of oxygen-eliminating device 4; Top at oxygen-eliminating device also is provided with instrument 8, the convenient intrinsic temperature and pressure of oxygen-eliminating device that reads at any time.
