Detailed Description
To make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be described clearly and completely with reference to the accompanying drawings, and obviously, the described embodiments are some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Example 1
Fig. 1 is a schematic diagram of the novel deep denitration powder injection accelerator in the furnace.
As shown in fig. 1, the present embodiment provides a novel in-furnace deep denitration powder injection accelerator, including: the device comprises a feed hopper 1, a three-way pipe 2 in threaded connection with the lower end of the feed hopper 1, an air inlet pipe 3 connected with one side of the three-way pipe 2, and a mixing chamber 4 connected with the other side of the three-way pipe 2; and a spraying mechanism 5 for supplying air through an air source is arranged in the air inlet pipe 3, and the spraying mechanism 5 is suitable for spraying high-speed airflow to convey powder falling along the feed hopper 1 to the mixing chamber 4. Negative pressure is formed in the three-way pipe 2 under the action of high-speed airflow of the injection mechanism 5, so that powder can smoothly enter the mixing chamber 4 for fully mixing, and the phenomenon of powder overflowing can be avoided.
Wherein, the air supply can but not be limited to adopt the fan, continuously be injection mechanism 5 air feed through the fan, make the three-way pipe 2 form the negative pressure in, make feeder hopper 1 the phenomenon that the powder emits can not appear.
In the embodiment, the three-way pipe 2 is connected with the air inlet pipe 3 by a flange; the three-way pipe 2 and the mixing chamber 4 are connected through flanges, and the joint of the three-way pipe 2, the air inlet pipe 3 and the mixing chamber 4 is good in tightness, high in bonding strength and convenient to detach through flange connection.
Optionally, the injection mechanism 5 includes: a sleeve 51 positioned inside the air inlet duct 3, and a nozzle 52 provided at the front end of the sleeve 51; the nozzle 52 extends into the tee 2; the nozzle 52 is adapted to emit a high-speed air flow to convey the powders falling down the hopper 1 to the mixing chamber 4. After the high-speed air flow is sprayed out from the nozzle 52, negative pressure is formed around the nozzle 52, so that the powder only falls from the feed hopper 1 and cannot flow upwards in a reverse direction, and meanwhile, the powder enters the mixing chamber 4 to form fluidization, so that the powder is uniformly mixed.
In this embodiment, the axis of the nozzle 52 coincides with the center line of the tee 2; the injection mechanism 5 further includes an adjuster 53; the regulator 53 is adapted to adjust the position of the nozzle 52 along the centre line. The axis of the nozzle 52 is overlapped with the central line of the three-way pipe 2, so that the high-speed airflow sprayed by the nozzle 52 can be horizontally sprayed out, and is sprayed into the central position of the mixing chamber 4, so that the powder can be uniformly mixed.
Optionally, the regulator 53 is fixedly connected to the sleeve 51, a sliding groove is formed in one side of the air inlet pipe 3, and the regulator 53 moves along the sliding groove, so that the nozzle 52 can move along the central line. When a high velocity air stream is blown across the barrier, the air pressure is relatively low near the ports above the lee side of the barrier, creating adsorption and resulting air flow. If the delivery capacity of the feeding hopper 1 is increased, the nozzle is adjusted to be close to the mixing chamber through the adjuster, the airflow is reduced from thickness to thickness so as to accelerate the flow rate of the gas, the gas forms a vacuum area at a position close to the mixing chamber, and the greater the negative pressure generated along with the forward movement, the greater the delivery capacity is realized.
In this embodiment, the nozzle 52 is provided with a ceramic coating, and ceramic is sprayed on the nozzle 52, so that abrasion of the powder and air to the nozzle 52 under high-speed mixing can be reduced, and the service life can be prolonged.
The inner wall of the mixing chamber 4 is provided with a ceramic coating, and ceramic is sprayed on the inner wall of the mixing chamber 4, so that the abrasion of powder and air on the inner wall of the mixing chamber 4 under high-speed mixing can be reduced, and the service life is prolonged.
In this embodiment, the upper and lower both sides wall of mixing chamber 4 is provided with thickening protective housing 41, through setting up thickening protective housing 41, avoids the high-speed air current that nozzle 52 jetted out to cause the wearing and tearing of mixing chamber 4, increase of service life.
The novel in-furnace deep denitration powder injection accelerator in the embodiment is empty and free of medium in the interior before use, and air is generally introduced for 3-5 minutes before use, so that a pipeline is ensured to be smooth, and the powder remained before last shutdown can be swept cleanly; if the inside of the novel in-furnace deep denitration powder jet accelerator is fully accumulated with powder, then the air source is started, so that the novel in-furnace deep denitration powder jet accelerator is seriously damaged, and the service life of the novel in-furnace deep denitration powder jet accelerator is easily shortened.
To sum up, the utility model discloses a novel degree of depth denitration powder sprays accelerator in stove utilizes the gas-solid two-phase flow principle, makes the three-way pipe 2 form the negative pressure under the effect of 5 high-speed air flows of injection mechanism, makes the powder can only follow feeder hopper 1 whereabouts and can not up reverse flow, avoids appearing the phenomenon of emitting the powder, and guarantees that the powder carries out intensive mixing in mixing chamber 4 is inside, makes the powder of misce bene do benefit to the transport, has improved system operation stability.
