Abstract
The invention relates to an automatic exhaust device for a deaerator. The automatic exhaust device is connected to an exhaust pipe at the top of a deaerator cylinder body and is formed by connecting heating power blowoff valves to the exhaust pipe at the top of the deaerator cylinder body in parallel. Outlets of the heating power blowoff valves are communicated with an outlet of the exhaust pipe. Compared with the prior art, by the adoption of the features of the heating power blowoff valves, according to the principle that the gas temperature is different, and thus the density is different, oxygen resolved in the working process of the deaerator is discharged through the heating power blowoff valves, and the automatic exhaust device has the advantages that the device is safe, reliable, simple in structure, low in failure rate, low in maintenance cost and convenient to operate, energy is saved, and the environment is protected.
Description
Technical field
The present invention relates to a kind of exhaust apparatus, especially relate to a kind of automatic exhaust device of oxygen-eliminating device.
Background technology
Current oxygen-eliminating device comprises the 60T/H oxygen-eliminating device of LOOS import, this equipment adopts Stress control temperature, dissolved oxygen in water is separated out to 102 ~ 105 DEG C in a large number through Steam Heating, the oxygen of separating out directly is discharged by oxygen-eliminating device top duct, and while discharge dissolved oxygen, a large amount of heats is also discharged together and causes a large amount of heat loss.
Chinese patent CN201935169U discloses Horizontal pipe-collected rotary membrane deoxidizing device, and current membrane deaerator all adopts vertical structure form, generally exerts oneself less, is only applicable to small unit, and a machine assembly is for an oxygen-eliminating device.A kind of Horizontal pipe-collected rotary membrane deoxidizing device, its composition comprises: deoxygenation head, water tank, and described deoxygenation head connects water tank, and deoxygenation head connects discharge line valve, discharge line valve connects the orifice plate that dams, and water tank connects magnetic flap level gauge, single-compartment balance container and pressure relief device.But this kind of oxygen-eliminating device does not still solve the problem of thermal loss.
Summary of the invention
Object of the present invention is exactly the automatic exhaust device providing a kind of safe and reliable, oxygen-eliminating device that structure is simple, easy to use in order to overcome defect that above-mentioned prior art exists.
Object of the present invention can be achieved through the following technical solutions:
An automatic exhaust device for oxygen-eliminating device, is connected on the blast pipe at oxygen-eliminating device cylindrical shell top, and this device is be connected in the heating power exhaust-valve on oxygen-eliminating device cylindrical shell top vent pipe in parallel, and the outlet of this heating power exhaust-valve is through the outlet of pipeline and blast pipe.
The front end of described heating power exhaust-valve is also provided with ball valve, and this ball valve is connected with arm in parallel on blast pipe.
Described heating power exhaust-valve is commercially available Si Paishake AV13 heating power exhaust-valve.
Described heating power exhaust-valve is provided with 7, is connected in parallel on the blast pipe at oxygen-eliminating device cylindrical shell top.
On described blast pipe heating power exhaust-valve in parallel position before be provided with electric-powered air release valve.
On described blast pipe heating power exhaust-valve in parallel position after be provided with stop valve, this stop valve close.
Oxygen can bring corrosion to metal, and oxygen corrosion can cause a lot of problem in boiler circuit.Boiler permits of no carelessness in anticorrosive work as special equipment, pressure vessel, thermal deaerator passes through steam heating water, make it the parameter reaching regulation, at this moment the oxygen in water is constantly separated out, air mixture is lower than vapor (steam) temperature at the same pressure, the present invention utilizes the feature of Si Paishake AV13 air bleeding valve, and namely heating power exhaust-valve can get rid of oxygen and other on-condensible gases of vapour system, can not reveal steam and reach energy-saving and cost-reducing object simultaneously.
Compared with prior art, the present invention utilizes the heating power air bleeding valve feature principle that density is different according to gas temperature difference, the oxygen parsed in the oxygen-eliminating device course of work is discharged by heating power exhaust-valve, have safe and reliable, structure is simple, failure rate is low, and maintenance cost is low, easy to operate, the advantages such as energy-conserving and environment-protective.
