Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail with reference to the accompanying drawings in conjunction with the following detailed description. It should be understood that the description is intended to be exemplary only, and is not intended to limit the scope of the present invention. Moreover, in the following description, descriptions of well-known structures and techniques are omitted so as to not unnecessarily obscure the concepts of the present invention.
The specific implementation mode is as follows: referring to fig. 1-2, a high-efficiency biomass hot water boiler comprises a boiler body 1, wherein a cavity is arranged in the boiler body 1. A fire grate 9 is arranged in the furnace body 1, an air inlet 3 and a slag outlet 2 are arranged below the fire grate 9 of the furnace body 1, and a fuel inlet 4 is arranged above the fire grate 9 of the furnace body 1; a heat exchanger 8 is arranged above the fire grate 9. Fuel is combusted on the grate 9 to heat the heat exchanger 8. The heat exchanger 8 comprises a plurality of heat exchange bodies 81, a water cavity 82 is arranged in each heat exchange body 81, the two sides of the lower portion of each heat exchange body 81 are connected with a water outlet pipe 7 through a pipeline, the top surface of each heat exchange body 81 is connected with a water inlet pipe 5 through a pipeline, a ventilating pipe 84 penetrating through the two sides of each heat exchange body 81 is arranged on the upper portion of each heat exchange body 81, and the ventilating pipe 84 is connected with a smoke exhaust port 6 through a pipeline. The water enters the interior of the heat exchanger 8 from the inlet pipe 5, then flows down around the vent pipe 84, is heated in the process, and finally flows out from the outlet pipe 7. The hot smoke generated by combustion flows upward to heat the heat exchange body 81, and is then discharged from the smoke discharge port 6 through the ventilation duct 84. Since the ventilation pipe 84 is located inside the heat exchanging body 81 and the water passing chamber 82 is formed around the ventilation pipe 84, the ventilation pipe 84 can also heat the water in the water passing chamber 82.
The cross section of the heat exchange bodies 81 is in an isosceles trapezoid shape, and the length of the upper bottom of the trapezoid shape is larger than that of the lower bottom of the trapezoid shape, so that the distance between the adjacent heat exchange bodies 81 is gradually reduced from bottom to top. Because the heat and the temperature in the flame that the burning produced and the hot cigarette lower more, consequently, the interval reduces and to make the heat more concentrated, and in addition, the change of interval also can produce certain disturbance to the air current for the inside heat diffusion of air current is with easily transmitting to heat-exchanging body 81 on the surface, has improved thermal utilization ratio.
Two sides of the heat exchange body 81 are tightly attached to two sides of the furnace body 1, and one side of the ventilation pipe 84 of the heat exchange body 81 is provided with a concave platform 83 to form a channel. Through which the flames and hot fumes produced by combustion can enter the ventilation tube 84.
The water inlet pipe 5 and the water outlet pipe 7 are positioned outside the furnace body 1, so that the structure of the furnace body 1 is more compact.
The inner wall of the furnace body 1 is provided with a heat preservation layer, so that heat loss is reduced.
In use, as shown in fig. 1-2, the ventilation pipe 84 is located inside the heat exchanging body 81, on one hand, the utilization rate of heat is improved, and on the other hand, the structure of the heat exchanging body 81 is more compact. The heat exchange body 81 with the isosceles trapezoid cross section further improves the heat exchange efficiency.
