Abstract
The utility model relates to a normal pressure vertical type hot pipe boiler which is composed of a chimney, a casing, an inner liner, a grate and a coal feeding opening. The inner of a hearth is provided with a water leg blocking wall, the top of the inner liner is provided with a hot pipe, an annular flue dipped in water is provided with a hot pipe, and the top cover of the casing is removable. The utility model has the advantages of structure simple and convenient production, the utility model can clean dust, remove dirt and change hot pipes at scenes, and the utility model can save 10-15% of steel.
Description
The utility model relates to a kind of atmospheric vertical heat pipe boiler.
The patent that heat pipe is used for the atmospheric vertical hot-water boiler is a lot, as CN 96222766.1, CN90222876.5, CN 90226579.2, CN 92223581.3 etc., the common drawback of these boilers is complex structures, makes trouble, can not field maintenance, can not the scene heat exchanger tube more, be difficult for on-the-spot deashing scale removal.
The purpose of this utility model be to design a kind of simple in structure, can field maintenance and more heat exchanger tube, deashing scale removal atmospheric vertical hot-water boiler easily.
This boiler is made up of chimney, shell, inner bag, fire grate, coal filling hole, it is characterized in that being provided with in the burner hearth water leg barricade, vertical or tilt heat pipe is housed at the inner bag top, flue gas divides two-way to enter chimney by the annular flue that is immersed in the water, and heat pipe also is housed on the annular flue.
Embodiment accompanying drawings of the present utility model is as follows.
Fig. 1 is the cutaway view of atmospheric vertical heat pipe boiler of the present utility model.
Fig. 2 is the A-A sectional schematic diagram of Fig. 1.
As shown in the figure, 1 is gap, and 2 is outlet pipe, and 3 is annular flue, 4 is shell, and 5 is inner bag, and 6 are the ash mouth that disappears down, and 7 is scaling hole, 8 is coal filling hole, and 9 is sewage draining exit, and 10 is flame retardant coating, and 11 is fire grate, 12 is water return outlet, and 13 is overfiren air port, and 14 is the water leg barricade, and 15 is gravity assisted heat pipe, 16 is cleaning door, and 17 is the liquid level meter, and 18 is chimney, 19 is the dish valve, and 20 is movable bell, and 21 is bleeder pipe.
The cross section of stove can be garden shape or square.
Whole body of heater falls to being sitting on the recessed brick ashpit, and air enters burner hearth by under the fire grate from ashpit.
Coal adds on the fire grate 11 from coal filling hole 8, and coal is after the burner hearth internal combustion, and flue gas is inverted to the burner hearth rear portion through the bottom of L type water leg, adds secondary wind the combustible after-flame in the flue gas at this through overfiren air port 13.Turn 90 degrees, enter annular flue 3 from the stove front portion, two passages entered the chimney 18 back emptyings that are positioned at the stove rear portion about this flue divided.
In the heat convection space that enlarges, be covered with gravity assisted heat pipe 15 vertical or that tilt, medium can be pure water or chemical conductive fluid in the pipe.High-temperature flue gas this heating heat pipe the bottom, the upper submerged of heat pipe in water, thereby carry out effective heat exchange.The inside heat pipe non flouling behaviour, the heat pipe outside is inserted in the part in the flue gas owing to be the light pipe of vertical hanging, so the surface is difficult for dust stratification, even long-pending on the tube wall have a certain amount of ash, beat the vibration heat pipe from lower deashing hole 6 after, ash also falls easily.The ash that falls accumulates in the bottom to fluid space, from lower deashing hole 6 be pushed into the stove back and fall into burner hearth through fire grate to ashpit, can not cause secondary pollution.The upper submerged of heat pipe outside can the hot-spot fouling in water, and a spot of dirt also is convenient to removing in that pipe is outer.Open movable bell 20, the people can enter the stove upper space from furnace roof top, after blowing out discharges water, can remove the outer incrustation of pipe easily, can also change the heat pipe of scrapping.Be inserted in the heat pipe on the annular flue 3, also can handle by this way.
In sum, owing to adopted heat pipe to replace water pipe to carry out heat exchange,, make processing and manufacturing also quite convenient so simplified the structure of boiler greatly, particularly can also on-the-spot deashing, scale removal, heat exchanger tube more.Actual fabrication shows that it can save steel 10-15% than the water-tube boiler of exerting oneself equally.
Claims (3)
