Technical Field
The utility model relates to a slag processing technology field especially relates to a slag heat braising dust arrester installation.
Background
The steel slag is waste slag generated in the metallurgical industry, the generation rate of the steel slag is 8% -15% of the yield of crude steel, and the problem of resource utilization of the steel slag is more and more emphasized along with the development of the steel industry. The steel slag hot braising is a common steel slag treatment method. The temperature of the high-temperature steel slag is very high when the high-temperature steel slag is poured into the hot stewing pool, and the temperature needs to be reduced to below a certain temperature before the hot stewing, so that water needs to be sprayed into the pool, the water is quickly vaporized, and ash content in the steel slag is mixed with the water and is always raised into a workshop; a great deal of dust can also be generated when the steel slag is dumped. In the existing industrial production, dust-containing steam generated in the process is hardly treated, or a roof cover is arranged on the top of a factory building to collect dust. However, the dust-containing steam which does not rise to the roof of the factory cannot be collected and treated, so that a large amount of dust-containing steam can be diffused in the factory, and the working environment is deteriorated.
The reason why the dust-containing steam cannot be collected is that a crane transversely runs above the hot stewing pond, a crane longitudinally runs when deslagging is carried out, an excavator works when slag is removed, and a bracket cannot be arranged beside the pond when a swing arm runs left and right. Due to the reasons, an effective dust collecting device cannot be installed above the hot stewing pool, and the difficulty in treating the dust-containing steam is increased.

Detailed Description
In order to make the above objects, features and advantages of the present invention more comprehensible, embodiments of the present invention are described in detail below with reference to the accompanying drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. The present invention can be embodied in many different forms other than those specifically described herein, and it will be apparent to those skilled in the art that similar modifications can be made without departing from the spirit and scope of the invention, and it is therefore not to be limited to the specific embodiments disclosed below.
It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only and do not represent the only embodiments.
Referring to fig. 1-3, the steel slag hot stewing dust collecting device comprises a hot stewing pool 4 with a pool cover 1, wherein one side of the hot stewing pool 4 is provided with an air suction cover bracket 3, the other side of the hot stewing pool is provided with a first air blowing port bracket 6, the air suction cover bracket 3 is provided with an air suction mechanism, the first air blowing port bracket 6 is provided with an air blowing mechanism, and the air suction mechanism is connected with a dust removing system. The blowing mechanism comprises an air blower 7, a blowing pipe is connected to the air outlet end of the air blower 7, and the tail end of the blowing pipe extends to the first blowing port support 6. And a second blowing port support 5 is arranged on one side of the first blowing port support 6 side by side, and the tail end of the blowpipe extends to the second blowing port support 5. The air suction mechanism comprises a suction fan 9, an air suction end of the suction fan 9 is connected with an air suction pipe, a valve 8 is installed in the air suction pipe, an air suction cover 2 connected with the air suction pipe is installed at the upper end of an air suction cover support 3, an air outlet end of the suction fan 9 is connected with an air outlet pipe, and the air outlet pipe is connected with a dust removal system.
During construction, an excavator is positioned at one side of the hot stewing pool 4, steel slag is pulled to a slag treatment workshop by a slag tanker, the average temperature is usually above 850 ℃, the steel slag is poured into the hot stewing pool 4 by a crown block, and a large amount of dust is raised when the steel slag is poured, and the dust is directly dispersed in the workshop. Before the thermal braising is started, the temperature is generally required to be lower than a certain temperature, so that water is required to be directly sprayed on the red slag, and evaporated water is raised along with a large amount of dust.
The steel slag hot stewing pond 4 is a device for generating dust-containing steam, and is generally recycled by a plurality of hot stewing ponds, and each hot stewing pond 4 generates a large amount of dust-containing steam before hot stewing. As the crane can transversely and longitudinally travel on the upper part of the pool, a dust collection cover cannot be arranged on the upper part of the pool, and a blowing-sucking type gas collection dust collection cover is adopted. In order to prevent the left and right swing arms of the excavator from impacting the blowing and sucking cover bracket in the slag removal process, the bracket is in an overhanging form, the bracket avoids the working radius range of the excavator, and the base and the support of the blowing cover bracket 3 and the second blowing port bracket 5 are arranged near the left side of the thermal stewing pool 4 as shown in the attached drawing 2.
When the steel slag is poured into the hot stewing pond 4, a large amount of dust can be generated, and then when water is sprayed, the water is vaporized into steam and rises, and a large amount of dust can be carried. And when the air flow speed in the air curtain is higher than the rising speed of the dusty steam or the raised dust at the same height and is higher than 1m/s, the dusty steam or the raised dust can be effectively intercepted and enter the suction hood 2, and then enter a subsequent dust removal system through the suction fan 9.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can substitute or change the technical solution and the inventive concept of the present invention within the technical scope of the present invention.
