Abstract
The utility model relates to the technical field of a boiler water circulation system, in particular to a boiler water circulation system with an air preheat function. The boiler water circulation system solves the technical problems that an air pre-heater is arranged at a smoke outlet of a boiler economizer and used for achieving heat exchange between smoke and air and providing hot air for an exhaust chamber of the boiler, moisture condensation easily occurs to cause sour rot, dust and dirt are accumulated on the heat area to affect heat exchange, the air-to-air heat exchange coefficient is low, and the heating surface is prone to being seriously abraded. According to the technical scheme, the boiler water circulation system with the air preheat function is formed by sequentially connecting a boiler barrel device, a user heat utilization device and an economizer end to end from the inlets of a water passage to the outlets of the water passage, and the boiler water circulation system with the air preheat function is characterized in that a water circulation air pre-heater is further connected in series on a connection pipeline of the outlet of the water passage of the user heat utilization device and the inlet of the water passage of the economizer.
Description
Technical field
The utility model relates to boiler water cycle systems technology field, particularly relates to a kind of boiler water cycle system that air preheat is provided.
Background technology
At present, the hot-air providing for boiler grate wind chamber, by being arranged on the flue gas of boiler economizer smoke outlet and the air preheater of air heat exchange is realized, and the air preheater of flue gas and air heat exchange has the following disadvantages, the one, owing to containing the easy dewfall of sulphur in flue gas, produce sour, the 2nd, the ash containing in flue gas, the long-pending heating surface of hanging of dirt affects heat exchange, the 3rd, flue gas and air heat exchange belong to gas one gas heat exchange, the coefficient of heat transfer is low, improve heat exchange efficiency, only has increase heating surface, cause consumption steel material large, the 4th, in flue gas, contain dust serious to heating surface wear.
Utility model content
The technical problems to be solved in the utility model is, be arranged on the flue gas of boiler economizer smoke outlet and the air preheater of air heat exchange and be embodied as grate wind chamber and provide hot-air to exist, easily dewfall produces sour, ash and the long-pending extension of dirt heating surface affects that heat exchange, the gas one gas coefficient of heat transfer are low, the deficiency of the easy heavy wear of heating surface.
For solving the problems of the technologies described above, technical solution adopted in the utility model is, design a kind of boiler water cycle system that air preheat is provided, it by drum device, user's heat utilization device and saver device at water passage, go out, import successively head and the tail connect to form, it is characterized in that: the air preheater that is also serially connected with water circulation on the water passage inlet connecting branch road of the outlet of the water passage of described user's heat utilization device and described saver device.
The utility model compared with prior art, owing to being designed with the air preheater of described water circulation in the described boiler water cycle system that air preheat is provided, realize with high temperature cold water and the cold air heat exchange of flowing out the water passage outlet of described user's heat utilization device, the hot-air that flows out the air preheater of described water circulation provides to grate wind chamber, its beneficial effect is, flow out described user's heat utilization device water passage outlet high temperature cold water and do not contain the sulphur in flue gas with the cold air of described high temperature cold water heat exchange, ash, dirt, dust, do not produce sour, heating surface is long-pending extension not, can there is not the problem of heavy wear heating surface, belong to gas one liquid heat exchange, the coefficient of heat transfer is high.In addition, the water that flows out the air preheater of described water circulation is reduced to low-temperature cold water from high temperature cold water, flow into again in the water passage of described saver device, strengthen with the flue gas temperature difference by described saver device, improved the coefficient of heat transfer of described saver device.
Accompanying drawing explanation
Figure is the boiler water cycle system architecture schematic diagram that air preheat can be provided.
The specific embodiment
Below in conjunction with accompanying drawing, provide the utility model preferred embodiment: the boiler water cycle system that air preheat can be provided, it by drum device 1, user's heat utilization device 2 and saver device 3 at water passage, go out, import successively head and the tail connect to form, it is characterized in that: the air preheater 5 that is also serially connected with water circulation on the water passage inlet connecting branch road 4 of the outlet of the water passage of described user's heat utilization device 2 and described saver device 3.During work, the flow of hot water in drum device 1, through user's heat utilization device 2, after the air preheater 5 of water circulation, saver device 3, flows back to again reciprocation cycle in drum device 1.Water in the air preheater 5 water passage import and export two ends connecting lines 4 of water circulation is respectively high temperature cold water and low-temperature cold water, and the import and export two ends of air preheater 5 air of water circulation are respectively cold air and hot-air, and hot-air is provided to grate wind chamber.
Claims (1)
