Detailed Description
The following further describes the embodiments of the present invention with reference to the drawings.
The technical scheme adopted by the invention is as follows:
the near-wall blowing type urea mixing device without the crushing structure, disclosed by the invention, as shown in fig. 1, 2 and 3, mainly comprises a cylinder body 1, a heat insulation cover 2, heat preservation cotton 3, a cover cap 4, a nozzle base 5, a mixing device 6 and the like. Wherein, mixing arrangement 6 welds inside barrel 1, and shroud 4 welds in barrel 1 upper end trompil department, and its upper end is used for welding urea nozzle base 5. The outside parcel of barrel 1 keeps warm cotton 3 and separates heat exchanger 2, guarantees the laminating of cotton 3 and barrel 1 of keeping warm through separating heat exchanger 2 and the welding of barrel 1 both ends.
The mixing device 6 mainly comprises a slotted hole short pipe 61, a Z-shaped baffle plate 62, an arc-shaped plate 63 and a rotational flow plate 64. The slotted hole short pipe 61 is welded above the Z-shaped partition plate 62, the arc-shaped plate 63 is tightly attached to the lower vertical plate of the Z-shaped partition plate 62 and welded through two slotted holes in the vertical plate, and the Z-shaped partition plate 62 is provided with two vertical slotted holes 10 and a transverse main slotted hole 11 which respectively face the inner wall surfaces and the arc-shaped plate 63 on two sides of the barrel 1. The rotational flow plate 64 is arranged behind the arc-shaped plate 63, and the edge of the rotational flow plate is welded with the barrel 1. The arc-shaped plate 63 is polished, so that the smooth surface is ensured, and meanwhile, the arc-shaped plate 63 is obliquely arranged from top to bottom, so that urea can be effectively prevented from being accumulated on the arc-shaped plate 63.
The Z-shaped partition plate 62 is provided with four long groove 8 holes. Respectively located at the two sides, the middle part and the lower end of the Z-shaped partition plate 62. The hole of the long groove 8 in the middle is transversely arranged at a position close to the wall surface of the arc-shaped plate 63, and the urea particles are blown on the wall surface of the arc-shaped plate 63 by guiding airflow to flow downwards along the arc-shaped plate 63. The airflow near the wall surface is blown to effectively reduce the accumulation of urea particles on the arc-shaped plate 63 and improve the evaporation rate of the urea particles. The 2 long groove 8 holes on the two sides are vertically arranged on the Z-shaped partition plate 62 close to the wall surface of the cylinder 1, air flow is guided to flow downwards along the wall surfaces of the cylinder 1 on the two sides, urea particles are swept on the wall surface of the cylinder 1, accumulation of the urea particles on the wall surface of the cylinder 1 is reduced, and the evaporation rate of the urea particles is improved. The hole of the long groove 8 at the lower end is transversely formed at the position close to the lower surface of the bottom of the arc-shaped plate 63, and air flow is guided to sweep along the lower surface of the arc-shaped plate 63, so that the temperature on the arc-shaped plate 63 is increased, and the arc-shaped plate 63 is prevented from forming crystals due to more temperature reduction. Meanwhile, the blowing air flow is blown out from the lower surface of the arc-shaped plate 63, and urea is prevented from falling into the bottom of the cylinder 1 at the tail part of the arc-shaped plate 63.
The working process is as follows:
in practical application, the mixing device 6 is respectively connected with a particle trap and an SCR catalytic unit in front and at back. The urea mixer has the effects of mixing air flow and urea, improving mixing efficiency, improving urea decomposition effect and reducing urea crystallization.
The urea nozzle base 5 is arranged on the cover cap 4 and is arranged obliquely, which is beneficial to increasing the travel distance of urea particles in the mixing device 6 and preventing the urea particles from falling on the wall too fast. The lower part of the nozzle base 5 is connected with a slotted hole short pipe 61, and 4 vertical long grooves 8 are arranged on the short pipe in the circumferential direction. When the air flow enters the mixing device 6, a small part of the air flow in the barrel 1 enters the slotted hole short pipe 61 through the flat holes uniformly distributed in the circumferential direction at the upper end of the slotted hole short pipe 61 to purge the bottom of the nozzle base 5, so that the urea is prevented from accumulating at the lower end of the nozzle base 5. Part of the air flow enters the short slotted pipe 61 through 4 evenly distributed slotted holes on the short slotted pipe 61, and smaller urea particles are prevented from being adhered to the pipe wall of the short slotted pipe 61. The air flow entering the slot short pipe 61 can quickly take away the urea particles sprayed from the position of the nozzle base 5, and the interaction between the air flow and the urea is enhanced.
The primary air flow enters the inner mixing assembly through the three slots 8 in the zigzag partition 62. The air flow entering from the hole of the long groove 8 in the middle flows down along the upper surface of the arc-shaped plate 63 and sweeps urea particles on the wall surface of the arc-shaped plate 63. The air flow entering from the long groove 8 holes on the two sides is blown along the wall surfaces of the cylinder bodies 1 on the two sides, so that the accumulation of urea particles on the wall surfaces of the cylinder bodies 1 is reduced. The air flow entering from the long groove 8 hole at the lower end is blown along the lower surface of the arc-shaped plate 63, so that the temperature on the arc-shaped plate 63 is increased, and the arc-shaped plate 63 is prevented from forming crystals due to more temperature reduction. Meanwhile, the blowing air flow is blown out from the lower surface of the arc-shaped plate 63, and urea is prevented from falling into the bottom of the cylinder 1 at the tail part of the arc-shaped plate 63.
Finally, the multiple air flows are merged at the position of the cyclone plate 64, and form a strong rotating air flow through the cyclone plate 64, so that the mixing uniformity of the urea and the NH3 is ensured.
The present invention is not intended to be limited to the particular embodiments shown above, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
