Description

The densely covered water-tube boiler of dislocation

Technical field

The utility model relates to the densely covered water-tube boiler of a kind of dislocation.

Prior art

Existing water-tube boiler, includes burner hearth, is provided with passage of flame above burner hearth, and the tail end of passage of flame is connected with chimney, is provided with water pipe in passage of flame.Existing water-tube boiler, no matter be biomass water pipe boiler, coal-fired water-tube boiler or fuel-oil-water pipe boiler, gas-water pipe boiler, comprise hot water pipe boiler and steam water pipe boiler, its passage of flame is all vertical up and down version, and blocked in order to prevent passage of flame, water pipe wherein is all designed to the vertical-shaped arrangement of consistency from top to bottom: the one, and the firepower in the middle of passage of flame is large, periphery firepower is little, skewness, affects heat transmission, and the thermal efficiency is low; The 2nd, between two drainpipes of consistency from top to bottom vertical-shaped arrangement, form Wheelchair Accessible, when flame and flue gas pass through from this passage, be difficult to ensure to flow with turbulent form, like this, the flame at close water pipe place and flue gas are because its heat is easily absorbed by water pipe, and temperature is lower, absorbed by the water in water pipe and middle heat is more difficult, temperature is higher, and the straight-through chimney of a large amount of heats is discharged from and slatterns, and the thermal efficiency is low; Blocked in order to prevent passage of flame, water pipe is arranged rarer, and heat-conducting area is little, and the thermal efficiency is low.

Utility model content

The densely covered water-tube boiler of a kind of thermal efficiency dislocation high and can be not blocked that is to provide of the present utility model.

For achieving the above object, the densely covered water-tube boiler of the utility model dislocation, include burner hearth, passage of flame, in passage of flame, be provided with water pipe, the tail end of passage of flame is connected with chimney, and between adjacent two drainpipes, arrange in the space that a rear row's water pipe is aimed between front drainpipe, be set with cigarette ash clear board in the outside of water pipe, on cigarette ash clear board, be fixedly connected with cigarette ash and remove pull bar.

The densely covered water-tube boiler of described dislocation, the distance between adjacent water pipe is identical.

The densely covered water-tube boiler of described dislocation, described passage of flame includes up and down side by side and three sections of passage of flames that are communicated with: the first passage of flame, the second passage of flame and the 3rd passage of flame, the ratio of distances constant in the distance in the distance in the first passage of flame between adjacent two water pipes of same row and the second passage of flame between adjacent two water pipes of same row and the 3rd passage of flame between adjacent two water pipes of same row is that 1.25:1:0.75 is to 1:1:1.

The densely covered water-tube boiler of described dislocation, the ratio of distances constant in the distance in the distance in the first passage of flame between adjacent two water pipes of same row and the second passage of flame between adjacent two water pipes of same row and the 3rd passage of flame between adjacent two water pipes of same row is 1.05:1:0.95.

Due to the densely covered water-tube boiler of the utility model dislocation, between its adjacent two drainpipes, arrange in the space that a rear row's water pipe is aimed between front drainpipe, when flame, flue gas collide after first row water pipe, form and circle round and walk around this water pipe, pass through from the space between first row water pipe, collide afterwards second row water pipe, form and circle round and walk around this water pipe, pass through from the gap between second row water pipe; In addition collide afterwards the 3rd drainpipe, form and circle round and walk around this water pipe, pass through from the gap between the 3rd drainpipe, flame, flue gas collide, walk around after multilayer water pipe with above-mentioned same method, enter into chimney and are discharged from.Therefore the thermal efficiency is high.

Due to the densely covered water-tube boiler of the utility model dislocation, its outside at water pipe is set with cigarette ash clear board, on cigarette ash clear board, be fixedly connected with cigarette ash and remove pull bar, cigarette ash clear board and cigarette ash are removed pull bar composition cigarette ash scavenge unit, can remove easily by this cigarette ash scavenge unit the cigarette ash depositing on water pipe, avoid passage of flame blocked, keep water pipe outer surface clean simultaneously, keep the good heat conductivility of water pipe, improved the thermal efficiency.

Due to the densely covered water-tube boiler of the utility model dislocation, its passage of flame is by three sections of passage of flame first passage of flames, the second passage of flame and the 3rd passage of flame arranged side by side and that be communicated with form up and down, flame, flue gas are through repeatedly turning round, circle round and moving ability upwards, downwards and discharged by chimney, passage of flame is long, in flame, flue gas and water pipe, the heat exchanger time of water is long, its heat has the more sufficient time to be absorbed by the water in water pipe, has improved the thermal efficiency; When mobile flame, flue gas collides corner top passage of flame wall, form and reflux, ensure that flame, flue gas flow with turbulent form in passage of flame, the thermal efficiency is high.

Due to the densely covered water-tube boiler of the utility model dislocation, ratio of distances constant in distance in distance in its first passage of flame between adjacent two water pipes of same row and the second passage of flame between adjacent two water pipes of same row and the 3rd passage of flame between adjacent two water pipes of same row is 1.05:1:0.95, therefore from the first passage of flame to the three passage of flames, the arranging density of water pipe increases gradually, although flame, the temperature of flue gas reduces gradually, but flame, flue gas is gradually reduced, be convenient to like this flame, the heat of flue gas is absorbed by the water in water pipe, improve the thermal efficiency.

In sum, the utility model dislocation water-tube boiler that gathers has been realized high and the object that can be not blocked of the thermal efficiency.Prove through inventor's many experiments, the temperature that the densely covered water-tube boiler of the utility model dislocation is discharged flue gas approaches room temperature, illustrates that the heat major part in flue gas is absorbed, and proves that the thermal efficiency is high.
