In order to realize the above object, the present invention adopts a technical solution as follows: A heat pipe type biomass hot-blast stove comprises a stove body, a combustion chamber and a heat exchange chamber are arranged in the stove body, the combustion chamber is communicated with the heat exchange chamber through a flue, and the heat exchange chamber is communicated with the stove body through an air flue; the heat exchange chamber includes a smoke discharge chamber and an exhaust chamber, the smoke discharge chamber is isolated with the exhaust chamber through an intermediate baffle plate, the intermediate baffle plate is provided with a plurality of heat exchange pipes of which one ends are located in the smoke discharge chamber, and the other ends are located in the exhaust chamber.
Preferably, the heat exchange pipes are arranged in a matrix and fixed on the intermediate baffle plate.
Preferably, the rear side wall of the smoke discharge chamber is provided with a smoke vent, the rear side wall of the exhaust chamber is provided with an air inlet, the smoke vent is communicated with the combustion chamber through the flue, the air inlet is communicated with an air outlet formed on the front side wall of the stove body through the air flue.
Preferably, the combustion chamber includes a first hearth and a second hearth, the rear side wall of the first hearth is provided with a first flue port which is communicated with the second hearth, the rear side wall of the second hearth is provided with a second flue port which is communicated with the smoke discharge chamber.
Preferably, the first flue port is located on the upper part of the rear side wall of the first hearth, and the second flue port is located on the lower part of the rear side wall of the second hearth.
Due to adoption of the above solution, the heat pipe type biomass hot-blast stove provided by the present invention increases the heat exchange efficiency of the bot-blast stove, prolongs the service life of the hot-blast stove, improves the reliability of the hot-blast stove, reduces the operation cost and maintenance cost of the hot-blast stove, and has strong practicability and market promotion value.
Brief Description of Drawings FIG.1 is an internal structure schematic diagram of the embodiment of the present invention.
Description of Embodiments
The embodiment of the present invention is described below in detail in conjunction with accompanying drawings, however, the present invention can be implemented in a multitude of different ways as defined and covered by claims.
As shown in FIG. 1, the heat pipe type biomass hot-blast stove of this embodiment comprises a stove body 1, a combustion chamber for combusting biomass fuel and a heat exchange chamber for heat conversion are arranged in the stove body 1, a flue 2 is formed between the combustion chamber and the heat exchange chamber, and an air flue 3 is formed between the heat exchange chamber and the stove body 1; wherein, the heat exchange chamber includes a smoke discharge chamber 4 and an exhaust chamber 5 which is located above the smoke discharge chamber 4, and an intermediate baffle plate 6 is arranged between the smoke discharge chamber 4 and the exhaust chamber 5, so that the smoke discharge chamber 4 and the exhaust chamber 5 are subjected to space isolation through the intermediate baffle plate 6; in order to change the structure form of the heat exchanger of the traditional hot-blast stove and avoid the problem that the heat pipes of the traditional hot-blast stove are swelled and ripped caused by thermal stress, the intermediate baffle plate 6 is provided with a plurality of heat exchange pipes 7 arranged in a matrix, one ends of the heat exchange pipes 7 are located in the smoke discharge chamber 4, and the other ends are located in the exhaust chamber 5, and therefore the heat exchange pipes 7 can realize the free flexibility of the cold and hot ends to carry out complete hot compensation and isothermal transfer functions, so that the heat exchange efficiency of the hot-blast stove is improved.
In order to optimize the functional structure of air exhaust and smoke discharge of the hot-blast stove, the rear side wall of the smoke discharge chamber 4 is provided with a smoke vent 8, the rear side wall of the exhaust chamber 5 is provided with an air inlet 9, and thus the smoke vent 8 is communicated with the combustion chamber through the flue 2, the air inlet 9 is communicated with an air outlet 10 formed on the front side wall of the stove body 1 through the air flue 3, so as to realize good transportation and circulation of smoke and hot air in the hot-blast stove.
