Abstract
A kind of denitration air atomization spray gun, is made up of nozzle (1), interior pipe (2), outer tube (3), interior pipe fixing device (4), support (5), O RunddichtringO (6), bolt (7), hybrid juction (8); It is characterized in that: described outer tube (3) tail end is provided with cooling-air pipe joint (13), the cooling air that can enter from cooling-air pipe joint (13) pours into outer tube (3) top from outer tube (3) tail end.The utility model, structure is simple, continues to pass into cooling air in outer tube (3) by cooling-air pipe joint (13), prevents that spray gun temperature is too high burns out spray gun; Entering compressed air by inlet suction port (9) makes ammoniacal liquor and gas synthesize abundant and be atomized after the injection, is fully mixed in flue gas and is conducive to ensureing that denitration effect, raising ammoniacal liquor utilization rate minimizing ammonia volume, minimizing afterbody ammonia are remaining.
Description
Technical field
The utility model relates to denitrating flue gas purification techniques field, particularly a kind of denitration air atomization spray gun
.
Background technology
Because the operating temperature of SNCR denitrification spray gun is higher, and flue gas flow rate is also fast, and carry a large amount of dust in flue gas secretly, the wearing and tearing for spray gun are also very severe; And the spray gun at burner hearth place exits burner hearth by propeller, the spray gun of cyclone inlet not only will continue logical compressed air and wear and tear to prevent spray gun, also should continue to pass into a cooling air in spray gun sleeve pipe, prevents that spray gun temperature is too high burns out spray gun; In addition spray gun also should with atomizing medium effect, atomizing functions can strengthen ammonia spirit particle and mix with inner flue gas of the stove, is fully mixed with to be beneficial to ensure denitration effect, improve that ammoniacal liquor utilization rate reduces ammonia volume, to reduce afterbody ammonia remaining.
Summary of the invention
For above problem, the purpose of this utility model is to provide a kind of denitration air atomization spray gun, that hybrid juction is provided with inlet suction port and water inlet pipe nipple, outer tube tail end is provided with cooling-air pipe joint, make gas and ammonia atomization fully manage outer atomization by water inlet pipe nipple and inlet suction port, reduce afterbody ammonia remaining.
The technical solution used in the present invention is: a kind of denitration air atomization spray gun, be made up of nozzle, interior pipe, outer tube, interior pipe fixing device, support, O RunddichtringO, bolt, hybrid juction, described interior pipe top is fixedly connected with nozzle, interior pipe tail end is fixedly connected with hybrid juction, and hybrid juction is provided with inlet suction port and water inlet pipe nipple; Interior pipe is arranged in outer tube body, it is made to be fixedly connected with position, outer tube top by interior pipe fixing device, it is made to be fixedly connected with outer tube tail end position by support and bolt, hybrid juction part on interior pipe exposes, support is provided with O RunddichtringO, is completed being tightly connected with outer tube by O RunddichtringO; It is characterized in that: described outer tube tail end is provided with cooling-air pipe joint, the cooling air that can enter from cooling-air pipe joint pours into outer tube top from outer tube tail end.
Described outer tube is outer is installed with flange connecting pipe by set bolt, and flange connecting pipe is provided with flange.
The utility model, structure is simple, enters compressed air and weares and teares to prevent spray gun, continue to pass into cooling air by cooling-air pipe joint in outer tube by inlet suction port, prevents that spray gun temperature is too high burns out spray gun; Make gas and ammonia atomization fully manage outer atomization by water inlet pipe nipple and inlet suction port, be fully mixed in flue gas and be conducive to ensureing that denitration effect, raising ammoniacal liquor utilization rate minimizing ammonia volume, minimizing afterbody ammonia are remaining.
