Abstract
The utility model discloses a steam water circulation system capable of causing the steam boiler to run in energy saving mode, which belongs to the steam boiler steam water circulation system running technology field. The main points of the technical scheme are: the height of the softening water highest line in the upper steam drum (103) in the steam boiler (1), i.e., the boiling softening water lever A, is lower than the height of the discharge outlet (402) of the heat exchanger (4). thus, the steam condensed from water after working can naturally return to the steam drum of the boiler which is producing steam with high temperature and high pressure, thereby, the pump for promoting the condensed water back to the boiler steam drum is not needed. The utility model has a simple structure, substantially reduces operation cost, improves environmental protection indexes, and can achieve zero discharge.
Description
Technical field
The utility model belongs to the technical field of steam boiler steam-water circulation system operation.
Background technology
At present, steam boiler is used very extensive in industrial production, and it produces steam, and for being that heat-exchange apparatus provides heat energy with hot equipment, simultaneously, in order to reduce production costs, enterprise also takes to economize on coal, economize on electricity, economize on water, save multiple economies such as vapour by every means.Steam boiler has brought a lot of benefits for industrial production and people's life.But, its steam-water circulation system part that also comes with some shortcomings, its weak point is: steam-water circulation system is in running, its steam condenses into water through acting, this condensate water turns back in the boiler-steam dome process must delivery pump, consumed power during this pump work, and its production cost is higher.For a long time, people do not expect, also basic nobody goes to think: take measures to make this condensate water to turn back to naturally in the drum of the boiler of producing high temperature and high pressure steam, omitting it carries condensate water to turn back to the interior pump housing of boiler-steam dome, reduce the construction investment of this pump, further reduce the production run cost, improve its economic benefit.
Summary of the invention
Task to be solved in the utility model provides a kind of steam-water circulation system that makes the steam boiler energy-saving operation, it can make steam turn back to naturally in the drum of the boiler of producing high temperature and high pressure steam through acting back condensate water, turns back to necessary delivery pump in the boiler-steam dome thereby omitted this condensate water.Thereby in the significantly reduced while of production cost, environmental protection index also gets a promotion, in the hope of reaching zero-emission.
The technical solution of the utility model is as follows:
A kind of steam-water circulation system that makes the steam boiler energy-saving operation, include: steam boiler 1, heat exchanger 4, top and lower position in its steam boiler 1 body of heater, be respectively arranged with steamdrum 103 and water drum 101, and, between steamdrum 103 and the water drum 101 with wall pipe 102 UNICOMs, use jet chimney 3 UNICOMs between the gas outlet 1031 of the steamdrum 103 that is provided with in the air intake 401 of its heat exchanger 4 and the steam boiler 1, use water return pipeline 5 UNICOMs between the water inlet 1011 of the water drum 101 that is provided with in the discharge outlet 402 of its heat exchanger 4 and the steam boiler 1, particularly: the maximum water level of the interior demineralized water of the interior steamdrum of steam boiler (1) (103), that is: the absolute altitude of demineralized water boiling back liquid level A is less than the absolute altitude of the discharge outlet (402) of heat exchanger (4).
In order to control the operating temperature of heat exchanger 4, be provided with steam stop valve 302 with the jet chimney 3 of air intake 401 UNICOMs of heat exchanger 4, and be provided with Water stop valve 502 with the water return pipeline 5 of discharge outlet 402 UNICOMs of heat exchanger 4.
In order to dispatch the production of many heat transmission equipment tissues, with the jet chimney 3 of gas outlet 1031 UNICOMs of steam boiler steamdrum 103 on steam distributor 2 is set.And, branch trachea 301, steam stop valve 3021 are set on jet chimney 3, with in parallel, series system heat exchanger 4,4 is set subsequently
1, 4
2Produce Deng many group heat transmission equipments.
Usually, the absolute altitude at the top of steam boiler steamdrum (103) absolute altitude that is equal to or less than heat exchanger discharge outlet (402) gets final product.
Technique scheme, in boiler-steam dome, annotate during sufficient demineralized water and the production run, steam need be entered in the water drum 101 of steam boiler through water return pipeline 5 through its condensate water of heat exchanger acting back by discharge outlet 402, because the liquid density of condensate water is greater than the steam state density of steam, and, the height of heat exchanger discharge outlet 402 greater than steam boiler steamdrum 103 under the condition of demineralized water boiling back liquid level A, condensate water just drops to the height of demineralized water boiling back liquid level A in the steam boiler steamdrum 103 naturally from the height of heat exchanger discharge outlet 402, and can continuously carry out continuously, turn back to necessary delivery pump in the boiler-steam dome thereby omitted this condensate water.
The beneficial effects of the utility model are as follows: owing to adopt technique scheme, steam is turned back in the drum of the boiler of producing high temperature and high pressure steam naturally through acting back condensate water, turn back to necessary delivery pump in the boiler-steam dome thereby omitted this condensate water.Thereby, realized the task that the utility model is expected, its method and structure is all simple.
