Abstract

A hot air heating furnace with heat pipe and biomass particle fuel is characterized in that a heat exchange box is separated by a tube plate into a hot air generating chamber at the upper part and a hearth flue at the lower part, and a heat pipe is welded and sealed in the staggered holes of the tube plate, and an inverted triangle particle fuel tank is arranged on one side of the heat exchange box; at the lower part of a material box, a speed regulation motor drives a twisting pipe to send the particle fuel through a feed pipe into the hearth grate, and the particle fuel in the role of a fan burns rapidly, the heat after combustion is arranged in the heat absorbing section of the heat pipe plain tube of the hearth for radiation and heat exchange, and is through convection heat exchange at the heat absorbing section of the finned heat pipe in the flue and is mutually changed to the finned heat release section of the heat pipe in the hot air generating chamber. The condensed latent heat is released by scour of the cold air flow of the fan and clean air is heated rapidly; the hot air pipeline is provided with a temperature sensor with the automatic temperature controller and speed regulation motor and the fan to form an interlocking system for fully automatic operation.

Description

Heat pipe biomass granule fuel hot blast warming stove

The utility model belongs to the device of preparation family heating clean hot air.

Vast winter, family's heating system of cold district mainly contained: 1, water heater hot water pipe net fin heating, it is slow to heat up.2, electric heating has electric heating spit of fland and electric heating wind cabinet, power consumption height, expense height.3, reel fuel hot blast warming stove only depends on more than 10 copper pipe heat exchange, and the thermal efficiency is low, and price is too high.

The purpose of this utility model provides a kind of cheap biological particles clean fuel that adopts, fin heat pipe superconduction heat exchange, the preparation pure air does not have the efficient hot blast warming stove of pressing.

The technical solution of the utility model is that heat exchange casing (2) internal tube plate (3) top is hot-air generation chamber (4), the bottom is burner hearth flue (5), super heat-conductive pipe (6) endotherm section stretches into burner hearth flue (5), heat release section places hot-air generation chamber (4), heat exchange casing (2) one sides are provided with the hopper (11) of del, hopper (11) triangular base is equipped with the pay-off that is driven by variable speed electric motors, particularly (12) on one side and twists (13) feed pipe (14), material is sent on the burner hearth fire grate (8), negative-pressure firing under air-introduced machine (15) effect, calory burning passes through heat pipe (6) endotherm section phase-change heat-exchange to heat pipe (6) fin heat release section, under air blast (16) cold wind washes away, discharge the latent heat of condensation and blow out hot blast fast, condensation working medium arrives heat pipe (6) bringing-up section by gravity reflux, move in circles, constantly cold air is heated.

The utility model has base plate (1), heat exchange casing (2,) at heat exchange casing (2) middle part assembly welding tube sheet (3), it is that hot-air generation chamber (4) and bottom are burner hearth flue (5) that casing (2) is separated into top, heat pipe (6) seal welding is in the fork round of tube sheet (3), the fin heat release section of heat pipe (6) places the hot-air generation chamber (4) on tube sheet (3) top, the light pipe endotherm section of heat pipe (6) stretches in tube sheet (3) lower furnace (5), heat pipe (6) fin endotherm section stretches into tube sheet (3) underflue (5), be provided with fire door (7) at the burner hearth place, in burner hearth, be provided with fire grate (8), deashing drawer (9) is arranged at fire grate (8) bottom, air intake duct (10), be provided with the hopper (11) of storage granular fuel in a side of heat exchange casing (2), in the anti-triangular base of hopper the pay-off that strand that variable speed electric motors, particularly (12) drives is held together pipe (13) is housed, granular fuel holds together the feed pipe (14) that (13) enter burner hearth (5) top through strand, sends into the fire grate (8) of burner hearth (5) and goes up burning.In flue (5) exit air-introduced machine (15) is housed, at hot-air generation chamber (4) rear portion air blast (16) is housed, gallery ports (17) are arranged at hopper (11) top, and whole box body is incubated with insulation material (18), the thin plate outsourcing.

In the utility model when work,, the adding granular fuel adds some granular fuels and solid alcohol on the fire grate (8) in burner hearth (5) in hopper (11), and light, the switch of switch power supply switch and feeding device, air-introduced machine (14) and air blast (15).Granular fuel burns under the air-introduced machine effect on fire grate (8).The required oxygen that burns is supplied with by the air intake duct (10) of fire grate (8) bottom.The light pipe endotherm section of the heat pipe (6) of heat of high temperature in being arranged in tube sheet (3) lower furnace (5) of burning absorbs radiations heat energy, and heat pipe (6) the fin endotherm section in flue (5) absorbs the heat convection heat again.Working medium in the heat pipe (6) absorbs the latent heat of vaporization rapidly, the latent heat of vaporization is transported to the fin heat release section of the heat pipe (6) that places hot-air generation chamber (4) with the speed of Ultrasonic wave like speed, under the air blast airflow scouring, discharge to air rapidly and coagulate clean latent heat, the Fast Heating air, the working medium of condensation is by the endotherm section of gravity reflux to heat pipe (6) bottom, the heat absorption vaporization moves in circles again, burnt gas is discharged after heat pipe waste-heated water-tank (bathing of supply family, life hot water) is discharged or entered to smoke pipe air-introduced machine (15), and the hot-air available pipe is switched to the room and uses.
