Abstract
The utility model relates to a boiler which comprises a base seat and a boiler body. The boiler body is added a cold water tank, a hot water adding pipe, a fume flow guide plate, a cold water allocator, etc. on the basis of a common boiler. The utility model has the advantages of reasonable structure, high thermal efficiency, lower energy consumption, small pollution, safety use, etc., and is used for the requirements of a plurality of aspects of heating, industrial production, etc.
Description
The utility model relates to a kind of boiler.
Boiler be produce, the staple in the life, advantage such as conventional boiler has that project organization is simple, manufacturing and use experience are abundant, it has brought very big help for people's production, life for many years.Along with the development of producing, people are constantly accumulating experience in the practice; boiler is carried out the improvement of various aspects; make boiler have some progressive to a certain extent; but present existing modified boiler but can not all reach comparatively ideal effect in energy utilization rate, environmental protection, security and various aspects.
The purpose of this utility model provides a kind of thermal efficiency height, and coal consumption is low, pollution is little, boiler safe in utilization.
The purpose of this utility model is achieved in that a kind of boiler, it comprises base, shaft, described shaft comprises the furnace wall, flue, by the furnace wall, the water cavity that flue forms, burner hearth, fire grate, the cold water inlet pipe, the hot water outlet pipe, stoke hole, chimney, the wind shelves, it comprises that also the cold water storage cistern of a step is arranged at the bottom, the heating pipe, smoke deflector, cold water dispenser, described cold water storage cistern is positioned at described fire grate top, its part is fixedlyed connected with described flue is tangent, and its bottom stage is relative with described coal filling hole, its remainder is fixedlyed connected with described flue by smoke deflector, and it communicated with described water cavity by communicating pipe; Described flue top is " recessed " shape; Described heating pipe is fixedly connected between described flue top and the described cold water storage cistern, and it is staggered arrangement; Described cold water dispenser is positioned at described cold water inlet tube top, and is fixedly connected in the described water cavity.
Described smoke deflector can be the serpentine of vertically arranging.
Described cold water dispenser can be ring-type, has on it along with the distance with cold water inlet tube increases and the limbers of increasing.
Described fire grate can be from having a down dip that coal filling hole begins.
The angle of inclination of described fire grate can be 8 °.
The utility model makes the various aspects of performance of this boiler all be improved owing to adopt above-mentioned design.
At first, the fire grate of inclination and bottom have the cold water storage cistern of step, make the burning of coal charge progressively carry out not only having reduced coal consumption, and having reduced pollution until sufficient combustion.The combustion process of coal charge is such on the fire grate, coal charge adds fashionable from coal filling hole, the evaporation preheating zone is just fired in the heating that at first enters cold water storage cistern bottom stage place, owing to be in boiler bottom air inlet place, the temperature end, is low herein, and coal burning is insufficient, thereby produce a large amount of not clean-burning flue gases, coal charge is pushed to the very hot oven district of burner hearth depths on this process and the fire grate that progressively tilting after the preheating, temperature can reach 700-800 ℃ herein, and coal charge is fully burnt.The not clean-burning flue gas that the combustion evaporation just of heating simultaneously preheating zone produces progresses into the very hot oven district along the cold water storage cistern bottom, also by further burning fully, so final cleaner flue gas that is produced after fully burning enters upper furnace after by smoke deflector.
Secondly, the serpentine smoke deflector not only makes flue gas risings that can evenly distribute, and has played very big dedusting effect, has further reached the purpose that reduces pollution.
Three, it is long-pending that upper furnace heating pipe's setting has not only increased the interior radiation heating-surface of burner hearth, improved the heat energy utilization rate, and its staggered arrangement mode and acting in conjunction of serpentine deflector, can make the flue gas of rising produce spiral air flow, like this, not only can evenly heat fully, and the dust in the flue gas also can fall along tube wall in the process that rises the heating pipe, play preventing that dust from flying out again from chimney, reduce the effect of polluting.
In a word, this boiler collecting efficiency height, energy consumption is low, pollution is little, characteristics such as safe in utilization, can satisfy actual needs.
Below in conjunction with accompanying drawing the utility model is elaborated.
Fig. 1 is the utility model shaft part-structure schematic diagram
Fig. 2 is Figure 1A-A face cross-sectional schematic
Fig. 3 is Figure 1B-B face cross-sectional schematic
As shown in Figure 1, 2, 3, furnace wall 1 and flue 2 are fixedlyed connected in the bottom, become water cavity 4 therebetween, and flue 2 inside become burner hearth 5, and fire grate 6 begins downward-sloping gradually 8 by coal filling hole 7 places.And be fixedly connected on the described flue 2, the fire grate of inclination 6 makes and pushes away that to add coal charge more convenient.Fire grate 6 tops have a cross section to be cold water storage cistern 9 oval, that a step 8 is arranged at the bottom, described step 8 is relative with described coal filling hole 7, described cold water storage cistern 9 is near the part and described flue 2 tangent fixedlying connected of coal filling hole 7, remainder is by vertically being that the smoke deflector 3 of serpentine is fixedlyed connected with described flue 2, gap between cold water storage cistern 9 and the flue 2 is the path 10 that flue gas rises, and described cold water storage cistern 9 communicated with described water cavity 4 by communicating pipe 15.Chimney 11 is connected with burner hearth 5 tops, on the described chimney 11 barge board 12 is arranged, thereby it can be used for regulating the combustion case of the velocity of discharge control coal charge of flue gas, and in addition, it also plays the effect of dedusting.Flue 2 tops are " recessed " shape, and two hot water outlet pipes 13 extend this recess.Be fixedly connected with staggered heating pipe 14 between flue top and the cold water storage cistern 9, be positioned at chimney 11 imports part heating pipe near being connected to heating pipe.Two cold water inlet tubes 16, be connected to 1 bottom, furnace wall, the cold water dispenser 18 of a fixedly connected annular on the flue 2 in the cold water inlet tube 16 top water cavities 4, limbers 17 is arranged on it, described limbers 17 progressively increases with the increase with the distance of cold water inlet tube 16, the effect of cold water dispenser 18 is to prevent cold water short circuit walking, causes heating uneven.The walking distance of water is such, the water section that enters the water cavity 4 from cold water inlet tube 16 entered in the cold water storage cistern 9 by communicating pipe 15, and rose among the heating pipe 14 by cold water storage cistern, was heated simultaneously, remaining water rises by cold water dispenser 18, also is heated simultaneously.Ash discharging hole 19 is arranged at the shaft bottom, sees fiery ash removing opening 21 on the shaft sidewall.For the boiler shaft can better be linked with base in use, there is fixedly outer ring 20 on the shaft base, and described base can form with brick system, also available metal is made, as long as can guarantee effectively fixedly shaft, clear up the ashes of fire grate bottom easily, guarantee that the furnace bottom ventilation gets final product.This kind boiler is applicable to heating, multiple needs such as industrial production.
