Background technique
The presence of oxygen in water is the main reason for boiler, heat exchanger and heat-net-pipeline corrode, this corrosion
The serious waste on the energy and fund is caused, while being hidden some dangers for the safe operation of equipment.National " low-pressure boiler water thus
Matter standard " equipped propose of boiler water deaeration device is clearly required in GB1576-2001.
For many years, people are being that traditional deoxidation method is preferably removed because being influenced to be not achieved by harsh external condition always
Oxygen effect cannot economically be run and worried.
Summary of the invention
The purpose of the present invention is overcome the deficiencies of the prior art and provide it is a kind of it is economical, easily remove oxygen in water
Equipment.
It realizes above-mentioned purpose, designs a kind of sponge iron filtering deaerating plant, it is characterised in that:
Including water softener, oxygen-eliminating device, deoxygenation water tank, the output end of the water softener is using the soft of pipeline connection oxygen-eliminating device
Water inlet pipe, the import of the outlet pipe connection deoxygenation water tank of oxygen-eliminating device, the outlet of deoxygenation water tank connect boiler, the bottom of oxygen-eliminating device
Portion is equipped with backwash water water inlet pipe；The pipeline, soft water inlet tube, the outlet pipe of oxygen-eliminating device, backwash water water inlet pipe, deoxygenation water tank
Outlet on be respectively equipped with solenoid valve, and the solenoid valve outer end being located on the outlet of deoxygenation water tank is additionally provided with hand-operated valve；
Each solenoid valve is separately connected controller；
Underfill in the oxygen-eliminating device has sponge iron grain.
The bottom of the soft water inlet tube is equipped with blowdown valve.
It is also equipped on the outlet pipe of the oxygen-eliminating device except iron flask.
The height of the sponge iron grain is 1100~1200mm.
The density of the sponge iron grain is 1500~1700kg/m3。
Compared with prior art, the present invention deoxygenation can be realized in room temperature, water inlet is without heating；System can supply water at any time, no
Need time；Deaerating effect is reliable and stable, out content of oxygen dissolved in water stabilization≤0.05mg/L, meets low pressure cooker water quality mark
It is quasi-；Installation overcomes heating power without particular/special requirement；Equipment can low position, simple process, without excessively high requirement for height, construction letter
It is single.
Detailed description of the invention
Fig. 1 is connection schematic diagram of the invention.
Specific embodiment
The present invention is further described now in conjunction with attached drawing.
Embodiment 1
Referring to Fig. 1, a kind of sponge iron of the present invention filters deaerating plant, it is characterised in that: including water softener, oxygen-eliminating device, removes
Oxygen water tank, the output end of the water softener 1 connect the soft water inlet tube 4 of oxygen-eliminating device 3, the outlet pipe of oxygen-eliminating device 3 using pipeline 2
The import of 7 connection deoxygenation water tanks 5, the outlet of deoxygenation water tank 5 connect boiler, and the bottom of oxygen-eliminating device 3 is equipped with backwash water water inlet pipe
8；The pipeline 2, soft water inlet tube 4, the outlet pipe 7 of oxygen-eliminating device, backwash water water inlet pipe 8, deoxygenation water tank outlet on point
Not She You solenoid valve, and be located at deoxygenation water tank outlet on solenoid valve outer end be additionally provided with hand-operated valve；Each solenoid valve
It is separately connected controller；Underfill in the oxygen-eliminating device 3 has sponge iron grain.
Sponge iron grain main component in the present invention is iron, loose porous internal structure, and the specific surface area provided is
Ten thousand times of 5-10 of common iron filings, can make oxygen and iron in water that thoroughly oxidation reaction occur rapidly, stablize oxygen in water
0.05mg/L is hereinafter, its reaction equation are as follows:
2Fe2+2H2O+O2→2Fe(OH)2；
2Fe(OH)2+2H2O+1/2O2→2Fe(OH)3；
It can be seen that a small amount of iron ion, generally 0.2-0.5mg/L are increased in water after deoxygenation, for hot-water boiler
For met the water standard of national regulation.But there is the water supply of strict demand for steam boiler or to water supply ferrous ion
It for deoxygenation, can install additional between existing oxygen-eliminating device and deoxygenation water tank except iron flask, namely add on the outlet pipe 7 of oxygen-eliminating device
Dress removes iron flask, and the ferrous ion in removal oxygen-eliminating device water outlet guarantees boiler feedwater quality.It is not shown in Fig. 1 except iron flask.
Further, the bottom of the soft water inlet tube 4 is equipped with blowdown valve 6, and the later period is facilitated to exclude to sink to tube wall bottom
Dirt.
Further, 1100~1200mm of height of the sponge iron grain.
Further, the density of the sponge iron grain is 1500~1700kg/m3。
The present invention can deoxygenation at normal temperature, water inlet without heating.It reaches identical operational effect with lower cost,
Operating pressure is 0.2~0.5Mpa；Water outlet oxygen content is 0.05mg/L, and operating temperature is 8~50 DEG C.
