Description
Title of the present utility model is the efficient hot blast generator of multiple-pass, belongs to dry, heating and ventilation technical field of heating.Purpose is to improve existing air-heater and improves the thermal efficiency.
Many industry need a kind of thermal source fork-like farm tool used in ancient China and remove the liquid that contains in the production technology in process of production.As the paint drying of automobile, outcase of refrigerator, the drying of industry such as papermaking, fabric, printing, cereal, medicine.Many buildings such as arenas, shop, workshop, office need heat supply, to guarantee heating and constant temperature.Yet the more existing air-heaters and the heating equipment ubiquity thermal efficiency low (being generally 20～45%), high, the bulky shortcoming of investment as the former.The utility model aims to provide a kind of continuous burning liquid, gaseous fuel, and the hot blast generator efficient, that the wind-warm syndrome air quantity is adjustable can provide the air of high temperature cleaning.
The utility model mainly constitutes (as shown in Figure 1) by following parts: burner (1), controlling organization (2), thermocouple (3), hot-blast outlet (4), exhanst gas outlet (5), inner core (6), circumferential weld (7) in the air, circumferential weld in the air (8), flue gas circumferential weld (9), the outer circumferential weld (10) of air, air pressure stabilizing chamber (11), heat insulation access door (12), preheating fan (13), underframe (14), combustion chamber (15), combustion fan (16) and gusset (17).Be described further below in conjunction with accompanying drawing.
As seen from Figure 1, hot blast generator body mainly is made up of five concentric circles made from metallic plate.Wherein inner core (6) and flue gas circumferential weld (9) and exhanst gas outlet (5) communicate, air pressure stabilizing chamber (11) and air outer (10), in (8), interior circumferential weld (7) and hot-blast outlet (4) communicate.Flue gas is discharged by exhanst gas outlet (5) through flue gas circumferential weld (9) from inner core (6), air then from air pressure stabilizing chamber (11) through air outside (10), (8), interior (7) three circumferential welds, at last by discharge in the hot-blast outlet (4).Both do not communicate each.Burner (1) and the combustion chamber of being made up of refractory material (15) connect with the opening part of inner core (6) left end.Inner core (6) right-hand member turns back and links to each other with flue gas circumferential weld right-hand member (9), and this flue gas circumferential weld (9) left end (being positioned at the burner place) links to each other with exhanst gas outlet (5).Combustion fan (16) is only supplied with burner (1) required air, is arranged near the burner (1).Preheating fan (13) is located at burner opposite one end, its outlet links to each other with air pressure stabilizing chamber (11) right-hand member, the latter's left end air outer circumferential weld (10) right-hand member outer with being positioned at flue gas circumferential weld (9) links to each other, the left end of the outer circumferential weld (10) of this air turns back and links to each other with circumferential weld (8) left end in the air in flue gas circumferential weld (9), the right-hand member of circumferential weld turns back and links to each other with outer interior circumferential weld (7) right-hand member of air of inner core in being somebody's turn to do, and the left end of circumferential weld (7) links to each other with the hot-blast outlet that places the outer ring, combustion chamber (4) in the air.Consider for ease of maintenance, be provided with heat insulation access door (12) at the right-end openings place of inner core.In order further to strengthen the heat transfer of flue gas to air, on the inside and outside wall of wall and flue gas circumferential weld, be welded with the metal rib (gusset 17) that quantity does not wait outer tube, in order to increase heat transfer area, improve air preheating temperature (see Fig. 2, Fig. 2 is the cross section of Fig. 1).Thermocouple (3) is with fork-like farm tool used in ancient China indication wind-warm syndrome and regulate burning.The open degree of regulating the blower fan late gate just can change air quantity, and the fuel metering quantity delivered can obtain different wind-warm syndrome with combustion air.Controlling organization can make burner light a fire automatically, and can make fuel and combustion air do ratio (PI) adjusting in institute's required airflow and wind-warm syndrome, thereby reaches best combustion, fuel-saving purpose.
The principle of this hot blast generator is: when fuel and combustion air obtain filling part burning by burner and combustion chamber, the inner core that high-temperature flue gas is mainly made by metallic plate based on the heat transfer type of radiation is passed to the air in the inner core outside, when this part flue-gas temperature reduces, pass through the flue gas circumferential weld again mainly in the mode of convection heat transfer' heat-transfer by convection, further heat is passed to the air in its outside.In this process, flue gas cools off gradually through two-pass, and the cold air that is preheated then obtains heating through the mode of three strokes with high speed convection gradually.
Air-heater body and two typhoon machines and controlling organization all are located on the steel underframe.So just make the hot blast generator form an integral body of moving capable of hoisting, as long as connect with the mains, fuel can move.
In sum, the utlity model has following characteristics:
1. energy-efficient traditional similar air-heater has only flue gas one-stroke and the single, double stroke structure of air, its thermal efficiency is all between 20～45%, the utility model is according to heat transfer theory, adopt unique flue gas two-pass, the multilayer sleeve horizontal type structure of air three strokes, the radiation rib that does not wait with special combustion system and quantity of joining makes the thermal efficiency up to more than 80%.Save the also big spoke degree of the energy significantly and reduced the equipment operating cost.
2. fast starting has reduced accumulation of heat, thereby has shortened from the time of the normal operation of lighting a fire owing to reduced the required refractory material in combustion chamber.
3. after the fully automatic operation burner is lighted a fire automatically,, can make fuel and combustion air make automatic ratio (PI) and regulate by required wind-warm syndrome air quantity.Required wind-warm syndrome can be set arbitrarily in 150～300 ℃ of scopes.
4. vertebration air-heater body of facility compact and two typhoon machines and controlling organization place on the underframe.Be convenient to installation and transportation, only need connect electricity supply fuel can move.
5. operating environment is well except discharged flue gas and hot blast, and equipment does not have the leakage part again.Because unique design, significantly reduced in the past Thermal Equipment to the heat dissipation capacity of environment, thereby provide the good working environment for the operator.
6. the strong the utility model of fuel tolerance is applicable to all gases fuel, as natural gas, town gas and producer gas.Be applicable to various liquid fuels too, comprise diesel oil and heavy oil and liquefied petroleum gas.
