It is a high-effective high-temp, novel hot-air indirectly-heating hot-air furnace which is made up by using heat-pipe heat-exchanger with high efficiency and small flow resistance and high-temp, radiation jet impact heat-exchanger with double-layer back-combustion furnace cavity by means of back flame path series-connection. Said invention also provides its concrete structure, its hot-air temperature can be up to 200-500deg.C and its heat efficiency can be up to about 85%.
Description
1 technical field:
The present invention relates to and prepare the coal-burning heat power supply device of hot-air, it needing to be widely used in hot-air heated technology occasion: the shaping and drying of drying of wood moulding, spinning coating dyeing and finishing industry, the vulcanization of rubber, chemical industry polymerization concentration and evaporation, the baking-curing of coating process, the heat drying of building materials industry etc..
2 background technologies:
The hot-blast stove of existing coal-fired preparation hot-air adopts burner hearth and tubulation structure, relies on the gas-gas heat exchange of metallic plate, pipe to add hot-air, because the coefficient of heat transfer of gas-gas heat exchange is low, hearth wall surface temperature height influences safe in utilization and life-span of hot-blast stove, adopt big volume burner hearth, increased the consumption and the cost of heat resisting steel, in service simultaneously because the thermal (temperature difference) stress difference of tube sheet easily causes tube sheet cracking, the flue gas string mixes, accidents caused, this hot-blast stove thermal efficiency is not high, and hot blast temperature is not high.
3 summary of the invention:
The objective of the invention is to design a kind of many technical deficiencies that overcome above-mentioned hot-blast stove, adopt that the double-layer grate naked light is counter to burn solution smoke abatement and dust control, and utilize the high-efficiency heat pipe heat exchanger of heat-tube vacuum phase transformation superconduction heat exchange and to the high-new coal-fired radiation jet flow hot pipe air heating furnace of being integral of alliance between giants of the radiation jet impingement heat transfer device of burner hearth high temperature outer wall, to remedy the blank of 200-500 ℃ of high-temperature heat pipe hot-blast stove.
Technical solution of the present invention:
Technical scheme of the present invention: the present invention by the outer jet chamber of the double-deck Back Fire stove courage in the burner hearth and quirk burner hearth and top cover, converge the radiation jet heat exchanger that air compartment and heating clamber form, burner hearth by anti-quirk with the front portion of the flue the heat exchange of heat pipe tube sheet under efficient, the novel heat pipe hot-blast stove of all-in-one-piece high temperature of connecting.
Double-layer inverse burning flue of the present invention is with arising from the interior front panel of burner hearth, and its internal upper part is the sealing coal chamber that anti-baked wheaten cake fire grate is arranged down, and lower fire grating is arranged above the cinder chamber of interior bottom, burns for the upper fire-grating naked light is counter in the middle of the two-layer fire grate, and lower fire grating is just to burn the combustion chamber.Firing door (air intake) is arranged respectively on the plate in front, the door that pokes fire, cleanout door (little air intake) regulates combustion conditions; Between flue is with furnace plate and coal chamber top with being quirk between the burner hearth top cover, have the anti-quirk with flue preceding bottom series connection on the burner hearth pretectum, all seal assembly welding, one determining deviation place is provided with the top jet tray at the distance top cover, the top jet tray equates with heating clamber inner casing size, with they seal weldings.Uniform spray-hole on the jet tray of top, its scope equates with the top cover size.Left and right and rear side has certain interval at burner hearth, interior is the jet chamber, in for converging air compartment, outer is three layers of heating clambers, jet chamber's Tong Hui air compartment has multistage z shape plate (ring aerofoil+jet tray+ring aerofoil) to separate, air by the heat exchange of heat pipe heating is introduced into heating clamber, behind top jet tray spray orifice jet flow impact top cover outer wall radiation heat transfer, enter three remittances of burner hearth air compartment step by step, impact the hearth outer wall radiation heat transfer through jet chamber's plate spray orifice jet flow step by step, receive the hot-air use occasion by afterbody jet chamber hot-blast outlet at last.
It is the hot-air generation chamber of arranging ratio-frequency welding fin heat pipe heat release section that heat exchange of heat pipe of the present invention is divided into top by tube sheet, the bottom is the flue of heat pipe heat-absorbing section, the preceding bottom of flue is with anti-quirk interface assembly welding, be welded with strip fin at the flue outer wall, with the lower air duct that places below the tube sheet, converge air port through the heating clamber both sides from heating by the air of flue and fin Convective Heating with lower air duct by the air of hot-air generation chamber heating and converge and enter heating clamber, to burner hearth and the heating of top cover radiation jet thereof.
The present invention compared with prior art has following technique effect:
(1), structure advanced person of the present invention is rationally distributed, adopt the heat exchange of heat pipe of different working medium heat pipe combinations in middle low-temperature flue gas heat exchange, heat-tube vacuum phase transformation superconduction heat exchange, exhaust gas temperature is low to be changed, thermal efficiency height, safe and reliable, simultaneously at flue outer wall assembly welding strip fin, place lower air duct together, the utilization rate of waste heat height, the air that is heated by heat exchange of heat pipe enters hearth outer wall hyperthermia radiation injection heat transfer, reduced the boundary-layer of burner hearth outer surface heat exchange greatly, reduce heat transfer resistance greatly, improve heat transfer intensity, the heat exchange efficiency height, the hot air temperature height of preparation, heated air and burning fume are the adverse current type heat exchange, and whole the radiation jet flow hot pipe air heating furnace thermal efficiency can reach about 85%, and the highest hot blast temperature can reach about 500 ℃.
(2), radiation of burner hearth efflux heat-exchanger advanced design, three rings of back three designs air channels are respectively the jet chamber, converge air compartment and heating clamber about burner hearth.The air of heat exchange of heat pipe heating enters to enter step by step after heating clamber heats again and converges air compartment and compile, impact burner hearth and top cover outer wall radiation heat transfer by spray orifice jet flow in the jet chamber, every grade is converged air compartment and jet chamber and is separated by three rings of z shape aerofoil, ring wind riser promptly is a jet tray, adopt multistage radiation jet impingement heat transfer can reduce the influence that jet flow is impacted cross-current greatly, the remittance air compartment, the jet chamber can be a plurality of, certain distance is arranged between each, form a plurality of injection heat transfers from top to bottom, all shut with ring flat-plate upper end, every jet chamber and remittance air compartment lower end, the outlet of a last jet chamber communicates with the next air compartment inlet that converges, and forms continual jet flow and impacts.
(3), firing door is set, poke fire door and cleanout door at the burner hearth front panel.The annular quirk that combustion flame is arranged at left and right, back three faces of burner hearth is to improve furnace plate radiation temperature, enhanced rad injection heat transfer intensity, hot blast temperature height.The combustion flame flue gas flow is long simultaneously, sufficient combustion, and smoke emissioning concentration is low, thermal efficiency height.
