Problems solved by technology

[0003] The main problems of the existing converter primary flue gas dry dedusting coarse ash conveying system are as follows: first, the built-in chain conveyor has a high failure rate and often gets stuck, which seriously affects the normal production of the converter; second, the coarse ash bin is located in the main workshop of the converter Inside, it is often restricted by the layout conditions of the steelmaking process, and the ash transportation channel for the car to enter and exit should be considered, which takes up a lot of indoor space; the third is that the price of each vacuum suction tanker is about 1 million yuan, and the investment is relatively high.

Embodiment Construction

[0024] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation manners of the present invention will now be described in detail with reference to the accompanying drawings.

[0025] like figure 1 As shown, the coarse ash pneumatic conveying system for converter primary flue gas dry dedusting of the present invention includes an evaporative cooling tower 1 , an ash discharge pipe 4 , a bin pump 10 , a pneumatic conveying pipe 17 and a coarse ash bin 18 connected in sequence.

[0026] The lower cone bucket of the evaporative cooling tower 1 is used to capture the coarse ash in the raw gas, and the evaporative cooling tower 1 is equipped with a material level gauge 3 and a rapping device 2 . The amount of coarse ash in the evaporative cooling tower 1 can be detected by the level gauge 3, and the rapping device 2 can ensure that the coarse ash can smoothly fall into the ash discharge pipe 4 to p...

Abstract

The invention relates to a converter primary flue gas dry dedusting and cinder pneumatic transmission system. The system comprises an evaporative cooling tower (1), a cinder discharge pipe (4), a bin pump (10), a pneumatic transmission pipe (17) and a cinder bin (18) which are sequentially connected, wherein a rapping device (2) and a charge level indicator (3) are arranged in the evaporative cooling tower (1); the pneumatic transmission pipe (17) is connected with a gas storage tank (14); the inlet of the gas storage tank (14) is connected with a first nitrogen gas pipe (13); the inlet of the first nitrogen gas pipe (13) is connected with a nitrogen gas main pipe; and the bin pump (10) is connected with the cinder bin (18) through the pneumatic transmission pipe (17). According to the invention, cinders can be transported by a common cinder transport truck, thereby greatly reducing the investment and saving the cost. Meanwhile, the invention reduces the equipment quantity and equipment maintenance amount, solves the problem that the height of the evaporative cooling tower is limited during dry dedusting reconstruction, is especially suitable for a project of reconstructing converter primary flue gas wet dedusting into dry dedusting, and has wide application prospects.

Description

technical field [0001] The invention relates to the field of environmental protection equipment, in particular to a coarse ash pneumatic conveying system for primary flue gas dry dedusting of a converter. Background technique [0002] With the increasing awareness of environmental protection, the primary flue gas of newly built and rebuilt converters mostly adopts dry dust removal. The coarse ash collected by the banana bend under the evaporative cooling tower is sent to the coarse ash bin in the main workshop of the converter under the action of gravity through the built-in chain conveyor, pneumatic flap valve and pneumatic double flap valve, and the coarse ash is directly discharged by the vacuum suction tanker Comprehensive utilization of Sinotrans. [0003] The main problems of the existing converter primary flue gas dry dedusting coarse ash conveying system are as follows: first, the built-in chain conveyor has a high failure rate and often gets stuck, which seriously ...
