Abstract
The low NOx exhaust left-right swing type direct flow coal powder combustor with adjustable gradient coal powder field includes nozzle seat, nozzle and nozzle driving unit. By means of separating the combustor into two parts including nozzle and nozzle seat and increasing cylindrical pin and nozzle driving unit, the present invention realizes the left-right swing of combustor and thus the hot state regulation of the jetting angle of the primary air and the secondary air, so as to create condition for putting off the mixing of the primary air and the secondary air inside the furnace and reducing generation of NOx inside the furnace.
Description
Technical field
The present invention relates to burner, particularly relate to a kind of adjustable low Nox left-right swing type direct flow coal burner of coal dust gradient fields that the circle of contact is arranged pulverized-coal fired boiler that is applied to.
Background technology
In the pulverized-coal fired boiler that the circle of contact is arranged, each angle is equipped with a plurality of straight-through pulverized coal burners, and each burner all has a fixing flow angle.The operating flame of the size of flow angle and boiler thermal-state full level and coal dust and Air mixing process in burner hearth is closely related.Studies show that, adjust the circle of contact of primary and secondary air, postpone the mixing of primary and secondary air and can adjust coal dust gradient fields in the stove, reduce the generation of NOx in the stove, but the burner of existing boiler all can't swing, and promptly the flow angle of each burner can't be adjusted when hot operation.
Summary of the invention
The object of the present invention is to provide the adjustable low Nox left-right swing type direct flow coal burner of a kind of coal dust gradient fields, solve the problem that exists in the prior art field.
The technical solution adopted for the present invention to solve the technical problems is:
Comprise nozzle carrier, nozzle body and nozzle body transmission device.The nozzle body afterbody inserts the nozzle carrier head, adopts two straight pins to connect between the two, and the nozzle body afterbody is an arc-shaped structure, can make nozzle body center on the straight pin swing, the nozzle carrier afterbody case of giving a dinner for a visitor from afar; One end of nozzle body transmission device comprises trundle, a universal joint and a pincerlike iron, and trundle one end is fixed on the wall of nozzle body bottom, and the other end inserts the centre bore of a universal joint, and a universal joint and a pincerlike iron phase connect; The other end of nozzle body transmission device comprises another universal joint, power transmission shaft, transmission axle bed, dial, clamping screw, rocking arm, locking nut, another pincerlike iron, crank, dial is fixed on the bellows wall; an end of rocking arm links to each other with dial with locking nut by clamping screw; the other end of rocking arm links to each other with power transmission shaft one end; driving sleeve with the fixing transmission axle bed of bellows wall on; cylindrical crank is set on the other end of power transmission shaft; crank inserts in another universal joint, another universal joint and another pincerlike iron phase company; The other end of two pincerlike iron has the external screw thread of different rotation directions, links to each other with female connecting rod respectively.
The useful effect that the present invention has is: by existing burner being divided into nozzle body, nozzle carrier two parts and additional straight pin and nozzle body transmission device, realized swinging of burner, thereby realized that the primary and secondary air flow angle is hot adjustable, for condition has been created in the mixing of postponing primary and secondary air in the stove and the generation that reduces NOx in the stove.

Fig. 2 is the A-A cutaway view of Fig. 1;
Fig. 3 is the B-B cutaway view of Fig. 1.
Among the figure: 1, nozzle carrier, 2, nozzle body, 3, straight pin, 4, pad, 5, split pin, 6, bellows, 7, universal joint, 8, power transmission shaft, 9, the transmission axle bed, 10, dial, 11, clamping screw, 12, rocking arm, 13, locking nut, 14, pincerlike iron, 15, split pin, 16, trundle, 17, split pin, 18, crank, 19, connecting rod.
The specific embodiment
The invention will be further described below in conjunction with drawings and Examples.
As Fig. 1, Fig. 2, shown in Figure 3, the present invention includes nozzle carrier 1, nozzle body 2 and nozzle body transmission device.Nozzle body 2 afterbodys insert nozzle carrier 1 head, adopt two straight pins 3 to connect between the two, and respectively with pad 4, split pin 5 location, nozzle body 2 afterbodys are arc-shaped structure, can make nozzle body 2 around straight pin 3 swings, the nozzle carrier 1 afterbody case 6 of giving a dinner for a visitor from afar; One end of nozzle body transmission device comprises trundle 16, a universal joint 7 and a pincerlike iron 14, trundle 16 1 ends are fixed on the nozzle body 2 bottom walls, the other end inserts the centre bore of a universal joint 7, and locatees with split pin 15, and a universal joint 7 links to each other with a pincerlike iron 14; The other end of nozzle body transmission device comprises another universal joint 7, power transmission shaft 8, transmission axle bed 9, dial 10, clamping screw 11; rocking arm 12; locking nut 13; another pincerlike iron 14; crank 18; dial 10 is fixed on bellows 6 walls; an end of rocking arm 12 links to each other with dial 10 with locking nut 13 by clamping screw 11; other end of rocking arm 12 links to each other with power transmission shaft 8 one ends; power transmission shaft 8 is enclosed within on the transmission axle bed of fixing with bellows 6 walls 9; cylindrical crank 18 is set on the other end of power transmission shaft 8; crank 18 inserts in another universal joints 7; and use split pin 17 location, another universal joint 7 links to each other with another pincerlike iron 14; The other end of two pincerlike iron 14 has the external screw thread of different rotation directions, links to each other with female connecting rod 19 respectively.
The course of work of the present invention is as follows: swing rocking arm 12, power transmission shaft 8 is rotated, thereby crank 18 is rotated around the B point, by universal joint 7, pincerlike iron 14, connecting rod 19 etc. thrust is passed on the trundle 16, nozzle body 2 is swung around center of circle A, behind definite each the burner pendulum angle of boiler thermal-state test, rocking arm 12 is fixed on the dial 10.Because the screw thread rotation direction of two pincerlike iron 14 is opposite, pivot link 19 can be regulated nozzle body 2 pendulum angles when rocking arm 12 is motionless, to regulate zero-bit.
The above-mentioned specific embodiment is used for the present invention that explains, rather than limits the invention, and in the protection domain of spirit of the present invention and claim, any modification and change to the present invention makes all fall into protection scope of the present invention.
