Abstract
The utility model relates to a de-aeration water-heating boiler. A de-aeration tower is arranged on a boiler, and a de-aeration heating device is a part of the heating surface of the boiler. The supplementing water and the circulating water which enter into the water-heating boiler can enter into the heating surface to heat after the supplementing water and the circulating water are de-aerated in the de-aeration tower of the boiler and then enter a heat supply network. The de-aeration water-heating boiler of the utility model overcomes the defects that the existing water-heating boiler is not provided with a de-aeration device and the de-aeration device is used inconveniently by the complex operation, and the defects that the boiler device is corroded seriously and the life time is reduced when the de-aeration device is not used. The de-aeration water-heating boiler of the utility model has the advantages of simple structure, reasonable design, high de-aeration efficiency, low cost, low energy consumption, less occupation space, centralized control operation and long service life.
Description
The utility model relates to a kind of deoxygenation hot-water boiler in the heating system.
Be dissolved with multiple gases in the recirculated water of hot-water boiler and the supplementing water, wherein oxygen is the most serious to the corrosion harmfulness of boiler and pipeline heating facility.And hot-water boiler in present most of heating facility and heating network are not established deaerating plant, though some heating facility has deaerating plant, but because of bulky troublesome poeration, the fireman seldom enables, therefore hot-water boiler and heat supply network equipment are caused heavy corrosion, the heating facility such as the hot-water boiler of no deaeration plant, pipeline and radiator generally have only 3-4 its service life, and the deaerating plant of prior art, as vacuum dust cather, analysis deaerators etc. are because equipment investment is big, power consumption is high, reasons such as operation operation complexity can not be at large and hot-water boiler and the supporting use of heat supply network facility.
The purpose of this utility model provides a kind of deaerating plant and hot-water boiler combines, and forms incorporate deoxygenation hot-water boiler, and it is few to have an equipment investment, and volume is little, easy-to-operate, and it is low to consume energy, and improves characteristics such as hot-water boiler and heating equipment service life.
The purpose of this utility model realizes in the following manner, oxygen-eliminating device is installed on the hot-water boiler, make it to become one, oxygen-eliminating device deoxygenation necessary energy is taken from the heating surface of hot-water boiler, moisturizing and recirculated water heating carrying out deoxygenation to hot-water boiler, water after the deoxygenation enters circulation pipe network, and air is through air bleeding valve emptying.For this reason, under the condition of deoxygenation, can reduce the boiler room capital expenditure, make hot-water boiler deoxygenation associating centralized Control, simplify the boiler operatiopn operation.
Figure of description (1) is a deoxygenation hot-water boiler structural representation of the present utility model;
Figure of description (2) is the another kind of embodiment of deoxygenation hot-water boiler of the present utility model.
With reference to Figure of description the utility model is described in detail:
De-aeration water-heating boiler of the present utility model is mainly by boiler heating surface (1), (2), oxygen-removing tower (12), pumping device (3), mixed water valve (4), (6), heat exchanger (5) circulating pump (7), small pump (8), liquid level gauge (10), air bleeding valve (13), thermometer (9), heat water-spraying's pipe (11) and heat supply network water valve (14) etc. partly form, oxygen-removing tower (12) is installed with the boiler one, and its pipeline is connected with boiler heating surface. (being known technology as for devices such as other parts of boiler such as shell, fire grate, subsidiary engine, air-introduced machines does not describe at this). On the top of oxygen-removing tower (12) air bleeding valve (13) is installed, liquid level gauge (10) is installed below the side, heat water-spraying's pipe (11) and boiler heating surface (2) join, shower nozzle and heat exchanger (5) are installed in the inside of oxygen-removing tower (12), the left end of heat exchanger (5) and boiler heating surface (2) join, right-hand member and small pump (8) join, the pumping device (3) that is provided with in mixed water valve and the circulating water pipework in the bottom of oxygen-removing tower joins, and is provided with mixed water valve (6) between moisturizing pipeline and circulating water pipework.
Embodiment 1: deoxygenation hot-water boiler of the present utility model is in operation when needing moisturizing, open small pump, water is squeezed into the moisturizing pipeline, enter the heat exchanger in the oxygen-removing tower, carry out preheating, enter boiler heating surface (2) heating (having thermometer to show) then, send into through shower from the heating surface top and carry out deoxygenation the oxygen-removing tower.To airborne release, the hot water after the deoxygenation enters circulating water pipework and enters boiler heating surface (1) heating back and send into heat supply network by the heat supply network water valve by mixing water valve and pumping device after heat exchanger heat exchange cooling escaping gas by air bleeding valve.
Embodiment 2: when deoxygenation hot-water boiler of the present utility model does not need moisturizing, close small pump and open mixed water valve (6), make a part of recirculated water enter oxygen-removing tower after the heat exchanger heating from mixing water valve (6), enter heating surface (2) heating, enter oxygen-removing tower again and after deoxygenation, enter circulating water pipe through mixing water valve (6) and pumping device (3), enter heat supply network from the heat supply network water valve through heating surface (1) heating by the bottom.
Embodiment 3: Figure of description (2) is the another kind of oxygen removal process of deoxygenation hot-water boiler of the present utility model, when its oxygen removal process is moisturizing, start small pump, open water compensating valve (7 ') and close mixed water valve (6), moisturizing enters heating surface (2) through pumping device (3), the heating back enters oxygen-removing tower from oxygen-removing tower (12) bottom that is installed in heating surface (2) top and carries out deoxygenation, air is from air bleeding valve (13) emptying, deaerated water enters heating surface (1) from oxygen-removing tower downside water pipe (15), and the heating back enters heat supply network by heat supply network water valve (14) again.
When hot-water boiler does not need to add moisturizing, can close water compensating valve (7 ') the small pump recirculated water that works on and squeeze into heating surface (2) heating through mixing water valve (4) and (6), send into then and enter heating surface (1) after oxygen-removing tower (12) deoxygenation and heat and send into heat supply network.
De-aeration water-heating boiler of the present utility model is compared with existing technology, have rational in infrastructure, the heating and the deoxygenation integration manufacture and design. Take that factory building is little to be easy to centralized management operation control, improved the utilization rate of complete equipment, oxygen removal efficiency height, the characteristics such as service life that can effectively prolong hot-water boiler and heat supply network heating equipment, have well economic and social benefit, fine popularizing value is arranged.
