Abstract
The present invention relates to a heat treatment furnace, and specifically to a heat treatment furnace of a pressure container, which is used for executing heat treatment to the larger-scale pressure container with cylindrical outline. The heat treatment furnace of the pressure container comprises a furnace body. The two sides at the base of the furnace body are respectively installed with one row of combustors. The injection direction of the nozzles of the combustors is the horizontal direction. Two rows of combustors at the two sides are staggered in the arrangement direction. The opposite side of each combustor is installed with an obstructing wall. A combustion chamber is formed between each group of obstruction wall and the nozzle of the combustor. The top of each combustion chamber is installed with a radiating cover plate. A gas channel is provided between the front end of each radiating cover plate and the obstruction wall thereby forming a plurality of combustion chambers at the base of the furnace body. Furthermore the two sides at the base of the furnace body are formed with two rows of staggered gas channels. The heat treatment furnace of the pressure container according to the invention has the advantages of uniform heating and excellent heat treatment effect when used for executing heat treatment to the large-scale pressure container.
Description
Technical field
The present invention relates to a kind of heat treatment furnace, specifically is a kind of heat treatment furnace of pressure container that the large pressurized vessel with cylindrical outline is heat-treated of being used for.
Background technology
Be used for process furnace that the pressurized vessel of large cylindrical shape outline is heat-treated, adopt fuel oil or combustion gas usually as thermal source.Existing heat treatment furnace of pressure container usually adopts at bottom of furnace body and fuel oil is set or gas burner heats being placed in the intravital pressurized vessel of stove, its major defect is, the furnace heat skewness, near the fuel oil atomizer temperature is too high, build-up of pressure container local superheating influences thermal effectiveness easily.
Summary of the invention
Technical problem to be solved by this invention is, a kind of homogeneous heating, heat treatment furnace of pressure container that thermal effectiveness is good are provided.
Heat treatment furnace of pressure container of the present invention includes a body of heater, respectively be provided with row's burner in the bottom of furnace body both sides, the injection direction of burner nozzle is a horizontal direction, two row's burners of both sides are crisscross arranged in orientation, each burner offside is provided with a barrier, form a combustion chamber between each group barrier and the burner nozzle, the top of each combustion chamber is provided with a radiation cover plate, leave an exhaust gases passes between each radiation cover forward end and the barrier, thereby form a plurality of combustion chambers at bottom of furnace body, and form the staggered exhaust gases passes of two rows in the bottom of furnace body both sides.
The present invention in use, the pressurized vessel tank body is placed in the body of heater middle part, the flame that burner produces is in the combustion chamber internal combustion, add the thermal radiation cover plate and produce radiant heat, simultaneously hot gas flow enters top body of heater inner chamber from the exhaust gases passes of both sides, and along rising on the pressurized vessel tank body both sides, and this type of heating makes uniform heat distribution in the body of heater, can not make pressurized vessel tank body local superheating, thereby improve heat treated heats.
Description of drawings
Fig. 1 is that end of the present invention is cut structural representation open;
Fig. 2 is a bottom of furnace body two dimensional structure synoptic diagram of the present invention.
Embodiment
As shown in the figure, this heat treatment furnace of pressure container includes a body of heater 1, respectively being provided with a row in the bottom of furnace body both sides is the burner 2 of fuel with fuel oil or combustion gas, the injection direction of burner nozzle 3 is a horizontal direction, two row's burners of both sides are crisscross arranged in orientation, each burner offside is provided with a barrier 4, form a combustion chamber 5 between each group barrier 4 and the burner nozzle 3, the top of each combustion chamber is provided with a radiation cover plate 6, leave an exhaust gases passes 7 between each radiation cover plate 6 front end and the corresponding barrier 4, thereby in bottom of furnace body formation a plurality of combustion chambers side by side, and at the staggered exhaust gases passes of bottom of furnace body both sides formation two rows.In the use, pressurized vessel tank body 8 is placed in body of heater middle part, and the flame heating radiation cover plate 6 of combustion chamber internal combustion produces radiant heat, and hot gas flow enters top body of heater inner chamber from the exhaust gases passes 7 of both sides simultaneously, and along rising on the pressurized vessel tank body both sides,
