Drawings
The present invention will be further described with reference to the accompanying drawings.
Fig. 1 is a schematic structural diagram of the present invention.
Wherein: 1. the device comprises an embedded sleeve, 2. An upper cylinder and a lower cone-shaped outer sleeve, 3. An air outlet pipe, 4. A support, 5. A rotary discharge valve, 6. A fixed baffle plate blade, a. A flue gas inlet, b. A flue gas outlet.
Detailed Description
The utility model discloses a manufacturing-by-design novel high-efficient spark trap of high temperature flue gas installs in high temperature flue gas sack cleaner entry, carries out the entrapment with the smoke and dust and the gas that produce among the high temperature smelting processes such as electric stove, argon oxygen stove, and through the metal dust that the entrapment particle diameter is greater than or equal to 100 mu m, optimize dust pelletizing system, protection dust remover sack, improvement sack life.
The novel high-efficiency spark catcher for high-temperature flue gas mainly comprises four parts, namely an embedded sleeve, an upper cylinder and a lower conical outer sleeve, an air outlet pipe and a rotary discharge valve. When smoke dust generated in high-temperature smelting processes of an electric furnace, an argon oxygen furnace and the like is treated, smoke gas firstly enters from top to bottom from an embedded sleeve at the flow speed of 10-12 m/s, then enters a conical ash bucket at the lower part of an outer sleeve with a larger space and collides with the wall of the ash bucket to reduce the flow speed of the smoke gas of the outer sleeve to the settling speed of dust with large particle size, the reduced smoke gas turns over to 180 degrees and flows out from a smoke gas outlet at the upper part of the outer sleeve through a 55-degree fixed baffle plate blade, metal dust with the particle size of more than or equal to 100 mu m is effectively trapped in the process to settle at the speed of 5.5m/s, and the metal dust is discharged from a rotary discharge valve at the lower part after being accumulated to a certain amount.
Wherein, operating mode wind speed in the inner skleeve: 10-12 m/s; working condition wind speed in the outer sleeve: 4-5 m/s; working condition and air speed of an air outlet duct: 10-12 m/s; the total resistance of the device is less than or equal to 600pa.
The dust-containing smoke enters the spark catcher from the embedded sleeve, then is decelerated by the conical outer sleeve at the lower part and turns to enter the upper part of the outer sleeve cylinder through the fixed baffle plate blades, and due to the difference of the space sizes of the embedded sleeve and the conical sleeve and the existence of the fixed baffle plate blades, the metal powder with large particle size sinks and falls under the action of gravity and the fixed baffle plate blades. In the high-temperature flue gas dust removal, the bag-type dust remover often burns out the bag because of the existence of high-temperature large-particle-size metal powder, even has the danger of fire under extreme circumstances, and this device has preprocessed large granule metal dust, makes this problem obtain fine solution.
