Abstract

The utility model relates to a heat pipe boiler which relates to the technical field of the heating and ventilation, the heat pipe boiler can be matched and used with a burning boiler, and can also make use of the industrial flue gas warming and heating. The heat pipe boiler comprises a main body which is composed of a casing body, a drum and a heat pipe element. The utility model is characterized in that the drum is arranged horizontally on the inner partition wall of the casing body, a first flue pipe which passes lengthways through the inner part of the drum is communicated with a secondary and a third flues at both sides of the partition wall, and the heat pipe element is vertically welded on a drum wall. The heating medium is guided into the cooling section of the heat pipe element by a water baffle plate which is welded at the upper wall in the drum, the heat is absorbed by heating sections on the flues and is transmitted rapidly to the cooling section, the heat and cold circulation is realized, and the heating purpose of the boiler is finished. The utility model has the advantages of simple structure, low cost, high heat efficiency, long service life and no pollution.

Description

Heat pipe boiler

A kind of tubular boiler relates to heat exchange and HVAC technical field.Tubular boiler can be used with combustion furnace, also can utilize the waste heat heat supply heating of the useless flue gas of industrial production.

The boiler that uses has pyrotechnics pipe and water pipe two big classes at present, and the flow media of firework tube boiler is that hot water and steam are produced in flame and the heat transfer of hot flue gas; Watertube boiler is that flue gas flow to conduct heat is produced hot water or steam outside water pipe, this dual mode all exist heating surface arrange unreasonable, that the heat exchange effect is low, water flows is uneven, easily generate incrustation scale, service life within 10 years, and needs deficiency such as periodic maintenance.

The utility model is in order to improve heat exchange efficiency, to overcome the above-mentioned not enough heat-pipe elements that adopts and do heat exchange coal amboceptor, water or steam are carried out Fast Heating, reaching the purpose of low consumption, energy-conservation heat supply heating.

Tubular boiler comprises housing, the boiler body that drum and heat-pipe elements are formed, drum lies in a horizontal plane on the partition wall that housing inner bottom part center line vertically is built into, its both sides form two flues in housing, there is a flue tube vertically to pass in the drum, the one end opening can join with combustion furnace outside housing, also can join with industrial waste heat flue gas source, the other end is opened on two flues of housing and other and communicates, the drum bottom is welded with heat-pipe elements, these vertical equidistant staggered heat-pipe elements that have axial fin, be to be welded on the drum downside wall by the metal sleeve that is enclosed within axial fin top, the end that heat-pipe elements is with ribbing is that bringing-up section is stretched out in the flue on partition wall both sides, heat-pipe elements one end of drum stack extension both sides is a cooling section, drum top one side is established entry (gas) mouth, opposite side sets out water (steam) mouth, and upper wall water inlet one face down bonding connects a fan-shaped water fender in the drum.

The utility model is owing to utilize heat-pipe elements as heat exchange coal amboceptor, the fast heat of heat transfer rate is imitated high, can utilize the low-temperature flue gas heat again, energy-saving effect is obvious, does not have water pipe in the pot body, scale hazard reduces, keep away and exert oneself general boiler water cycle and water pipe leakage accident, the heat-pipe elements apart arrangement, repair and replacement are convenient, long service life, floor space is little, cost is low, and smoke medicining dust-removing effect is good.

(1) drum, (2) heat-pipe elements, (3) water fender, (4) water inlets (gas) mouth, (5) water outlet (gas) mouth, (6) exhanst gas outlet, (7) housing, (8) partition wall, (9) fin, (10) welded tube, (11) cooling section, (12) bringing-up section, I, II, III are flue among the figure.

Embodiment of the present utility model is described in detail in detail in conjunction with the accompanying drawings:

The body of tubular boiler is made up of drum (1) and heat-pipe elements (2), housing (7) is to be made of insulating refractory, housing (7) inner bottom part center line is built refractory material partition wall (8), drum (1) lies in a horizontal plane on the partition wall (8), the both sides of partition wall (8) are respectively flue II and flue III, there is a metal tube flue I vertically to pass in the drum (1), the one end opening is outside housing (7), can join with various combustion furnaces, also can join with industrial production waste heat flue gas source, the other end is opened in the housing (7) and the flue II, the flue III communicates, drum (1) bottom is welded with heat-pipe elements (2), heat-pipe elements (2) is the gravity type heat pipe that has axial fin (9), be with welded tube (10) on fin (9) top, the vertical equidistant staggered heat-pipe elements (2) of many groups is welded on drum (1) downside wall by welded tube (10).One end of heat-pipe elements (2) with ribbing (9) is that bringing-up section (12) is stretched out in the flue II, in the III, the other end is the flue I both sides of cooling section (11) in drum (1), drum (1) top one side is provided with entry (gas) mouthful (a 4) opposite side and is provided with water outlet (gas) mouthful (5), the interior upper wall water inlet of drum (1) (gas) mouthful (4) one face down bondings have fan-shaped metal water fender (3), cold water (gas) enters from water inlet (gas) mouthful (4), import the cooling section (11) of heat-pipe elements (2) through water fender (3), the bringing-up section (12) of heat-pipe elements (2) absorbs and enters the flue II by the flue I, the heat of III also evenly and rapidly conducts to cooling section (11), make water (gas) heating rapidly, constantly deliver to the user from water outlet (gas) mouthful (5), flue gas is discharged by floss hole (6), so repeatedly the circulation company that the finished tubular boiler heat supply function that continues.
