Abstract
The utility model relates to the field of continuous-heating efficient hot air generator air distribution, and in particular relates to a hearth hood. The hearth hood comprises a hood body, a cavity is arranged in the hood body, the upper parts of the hood body and the cavity are in tapered structures, and the lower parts of the hood body and the cavity are in cylindrical structures; the upper part of the hood body, in the cylindrical structure, is provided with an upper ring of air outlets and a lower ring of air outlets circumferentially arranged on the hood body, the central line of the ring of air outlets at the upper end is horizontally arranged vertical to axes of the hood body, and an included angle is formed by the central line of the ring of air outlets at the lower end and the axes of the hood body, and the central line is downward along the axis. For solving the defects that fuel is easy to stack at the top of the hood for coking and the air outlets are easy to block in the prior art, the hearth hood disclosed by the utility model is good in venting effect, and the fuel is hard to block at the hood.
Description
Technical field
The utility model relates to the hot High Efficiency Thermal gas producer cloth wind field of continuing, and relates in particular to a kind of wind cap for hearth.
Background technology
The hot High Efficiency Thermal gas producer that continues adopts the fluidized bed combustion mode to carry out fuel combustion.In the hot High Efficiency Thermal gas producer that continues, coal is broken after crusher machine becomes to be less than the coal grain of 10mm and adds combustion chamber (burner hearth).Combustion chamber bottom is furnished with perforated distributor, below air distribution plate, is connected with air compartment, air blast by air compartment the blast cap on air distribution plate air is sent into to burner hearth, blow the coal grain and burn red yellow ground and make it be in fluidized state, thereby produce heat.Overfall or the cold cinder notch of the lime-ash of after-flame in being arranged in burner hearth discharges out of the furnace.Air by the aperture of blast cap, blows yellow ground by air compartment and the coal grain makes it be in fluidized state, existing blast cap top is spherical, yellow ground and fuel easily cause at spherical blast cap top to be piled up and coking, affect entering of air, affect the boiling of producer, thereby reduce its caloric value, and the exhaust vent operated by rotary motion is at the top of spherical blast cap side, exhaust vent easily stops up, and in the course of time, can cause to whole drying system the adverse consequences of stopping production.
Summary of the invention
The utility model overcome that fuel in above-mentioned prior art is easily piled up at the blast cap top and coking and exhaust vent easily blocked shortcoming provide a kind of fuel to be difficult for blocking, wind cap for hearth that ventilation effect is good at blast cap.
The technical solution of the utility model is achieved in that a kind of wind cap for hearth, and it comprises the cap body, and described cap body inside is provided with cavity, and the top of described cap body and described cavity is pyramidal structure, and bottom is cylinder-like structure; The top of described cap body cylinder-like structure is provided with the exhaust vent of the upper and lower two all cloth of circle on the cap body.
The center line of the described exhaust vent of a circle that is positioned at upper end in two circles is horizontally disposed with perpendicular to the cap body axis.
Center line and the cap body axis of the described exhaust vent of a circle that is positioned at lower end in two circles form angle, and this center line is downward along axis.
Good effect of the present utility model is as follows: the disclosed above-mentioned wind cap for hearth of the utility model, traditional spherical blast cap is improved to pyramidal structure, and make fuel be difficult in blast cap top blocking, coking; Two circle exhaust vents are set simultaneously, and exhaust vent is positioned at the upper end of cylinder-like structure, with the exhaust vent of traditional blast cap, is positioned at the blast cap top and compares difficult the obstruction, and ventilation effect is good, is conducive to the abundant burning of fuel.The such setting of the utility model has overcome the problem of blowing out cleaning coking, has improved the efficiency of combustion of the hot High Efficiency Thermal gas producer that continues.
The accompanying drawing explanation
Fig. 1 is the structural representation that dissects of the present utility model.
The specific embodiment
As shown in Figure 1, a kind of wind cap for hearth, be applied to continue in hot High Efficiency Thermal gas producer, and it comprises cap body 1, and cap body inside is provided with cavity 2, and this cap body Lower Half is embedded in burner hearth, is cylinder-like structure, and its bottom offers the air inlet be communicated with bellows; In this cap body top setting and burner hearth, described cap body and cavity upper end are pyramidal structure, the top of cylinder-like structure offers the exhaust vent that two circles are arranged above and below, be respectively the first exhaust vent 3 and the second exhaust vent 4, two iris out the wind orifice ring around the pyramidal structure bottom, the center line of the first exhaust vent and cap body axis are perpendicular, and in an angle, and this center line is downward along the cap body axis for the center line of the second exhaust vent and cap body axis shape.
When the air blast of producer, air is sent in burner hearth through blast cap by air compartment, blown fuel and make it be in fluidized state, because cap body and cavity top are pyramidal structure, fuel is difficult for stopping on top, therefore fuel is difficult in this blocking, coking.Exhaust vent is looped around pyramidal structure bottom, is difficult for blockedly, and ventilation effect is good, is conducive to the boiling of producer, and then fuel can fully burn, and often blowing out processing blocking, coking problem.
Claims (3)
1. wind cap for hearth, it comprises the cap body, and described cap body inside is provided with cavity, and it is characterized in that: the top of described cap body and described cavity is pyramidal structure, and bottom is cylinder-like structure; The top of described cap body cylinder-like structure is provided with the exhaust vent of the upper and lower two all cloth of circle on the cap body, and described exhaust vent is looped around cap body pyramidal structure bottom.
2. a kind of wind cap for hearth as claimed in claim 1 is characterized in that: the center line of the described exhaust vent of a circle that is positioned at upper end in two circles is perpendicular to the cap body axis.
