Abstract
A dust removing device for the oxidizing period of electric steel making relates to the technical field of high-temperature smoke gas dust removing equipment, and is characterized in that a smoke inlet pipe and a smoke outlet pipe are respectively connected to the middle parts of the end surfaces of the left and the right ends of a box body; a dust collecting pipe is connected on the lower plate surface at the right end of the box body; a water inlet pipe is fixed on the upper plate surface at the left end of the box body; the lower end of the water inlet pipe is connected with a nozzle inside the box body; two cambered dust collecting wind shields with rightward concave surfaces are arranged in sequence and connected between the upper and the lower plate surfaces on the right side of the nozzle; and two cambered air flow distributing plates with leftward concave surfaces are respectively mounted between the two dust collecting wind shields and arranged in a staggered manner with the dust collecting wind shields. Due to an abrupt section expansion after smoke dust enters the box body, a large amount of air flow eddy is generated at the expanded part, so that the velocity of the air flow accessing the box body is sharply reduced, and the dust is deposited under a decreased suspending power in the air flow and the continuous and repeated resistance of water spray and atomization as well as the wind shields, thereby achieving the purpose of dust removing. The device has the advantages of simple structure, convenient examination and maintenance, exemption from moving components and high dust removing effect.
Description
Technical field
The utility model relates to the high temperature fume dust removal equipment technical field, specifically a kind of Electric furnace steel making cleaning apparatus oxidation period.
Background technology
Electric furnace steel making all can produce a large amount of flue dust oxidation period, and these flue dust severe contamination surrounding environment influence people's life and growth of surrounding plants.Existing Electric furnace steel making fly-ash separator equipment is huge, complex structure, and the cost height, interior serious wear, the maintenance cost height, dust removing effects is bad.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of simple in structure, and maintenance is convenient, and cost is low, Electric furnace steel making cleaning apparatus oxidation period of good dedusting effect.
The purpose of this utility model is achieved in that this Electric furnace steel making cleaning apparatus oxidation period is made up of casing, smoke-intake pipe, pipe, dust collection pipe, control of dust windsheild, airflow-distribution board, end face middle part, two ends, the casing left and right sides is connected with smoke-intake pipe and pipe respectively, be connected with the dust collection pipe on the right-hand member lower face, fixing water inlet pipe on the left end upper face, the water inlet pipe lower end links to each other with the intravital shower nozzle of case; Be connected with the arc control of dust windsheild of two concave surfaces that are arranged in order between the upper and lower plates face of shower nozzle right part towards the right side, be respectively equipped with between two control of dust windsheilds two concave surfaces towards a left side with the staggered arc airflow-distribution board of control of dust windsheild.
During use, flue dust enters casing by smoke-intake pipe, because flue dust enters cross section sudden enlargement behind the casing, air-flow can produce a lot of vortexs in expansion place, under the effect of control of dust windsheild and airflow-distribution board, air-flow and plate face collide mutually, cause the flowed energy loss, and the suspending power of dust in air-flow descends; The a large amount of water smoke of shower nozzle ejection simultaneously increases weight of dust in the flue gas, makes dust and pneumatic separation, and the dust that precipitates flows out through the dust collection pipe under the flow action of shower nozzle ejection, thereby reaches the dedusting purpose.
Advantage of the present utility model: because flue dust enters cross section sudden enlargement behind the casing, air-flow can produce a lot of vortexs in expansion place, make and enter the intravital gas velocity anticlimax of case, the suspending power of dust in air-flow descends, and precipitates under the spray atomizing of water and baffle plate constantly stop repeatedly, reaches the dedusting purpose, it is simple in structure, repair and maintenance is convenient, no movement parts, dust removing effects height.
