The device is through utilizing compressed air behind the Laval nozzle speed-up, produces the negative pressure at the section entrance that accelerates, leans on the negative pressure to take away hot well jar interior carbon monoxide, discharges the high altitude along with compressed air together, realizes safe the diffusion. And meanwhile, in order to prevent negative pressure from adversely affecting the hot well tank, an air supplementing pipe is also arranged on the hot well tank.
Description
Technical Field
The utility model relates to a device that toxic gas (CO) in the zero meter vacuum hot well jar is taken out fast to negative pressure to easily clear up fast and change.
Background
During smelting of the RH furnace and the VOD furnace, oxygen blowing and decarburization processes are carried out, meanwhile, a large amount of carbon monoxide gas is generated in a vacuum tank, when the carbon monoxide gas is pumped to a condenser by a vacuum pump, part of the carbon monoxide flows into a 0-meter hot well tank along with water and turbid circulating water which are formed by cooling steam in the condenser. Because carbon monoxide is insoluble in water, a large amount of carbon monoxide can overflow from water, and aggregation is formed above the interior of the hot well tank, if the carbon monoxide cannot be timely dispersed at high altitude, leakage is extremely easy to cause, and personal safety of field personnel is affected.

Detailed Description
The utility model provides a device for rapidly pumping out toxic gas in a zero-meter vacuum hot well tank by negative pressure.
The core of the scheme is as follows: compressed air is subjected to primary speed increasing after passing through the Laval nozzle, and the accelerated air flow enters the speed increasing section of the Laval ejector and is subjected to secondary speed increasing after compression, adiabatic expansion and secondary speed increasing to become high-speed air flow which is discharged to high-altitude atmosphere through the diffusing pipeline. Because high-speed gas flows through, negative pressure can be formed at an inlet of the speed-increasing section, and carbon monoxide gas gathered in the hot well tank can flow to the inlet due to pressure difference and is discharged to the high altitude along with compressed air, so that safe diffusion is realized. Simultaneously, the speed-up section of the device is connected with the flange of the diffusion pipeline, the hot well tank and the compressed air through the flange, so that the device is easy to quickly replace, overhaul and clear up accumulated slag.
The device comprises compressed air, a pressure stabilizing air bag, a Laval nozzle, an upper flange, a lower flange, a compressed air acceleration section, a suction inlet flange, a zero-meter vacuum hot well tank, an air supplementing pipe and the like. Compressed air passes through a pressure stabilizing air bag and is accelerated once through a Laval nozzle at a certain degree and flow rate, the accelerated air flow enters an acceleration section of the Laval ejector and is accelerated twice through compression, heat insulation and expansion, and finally high-speed air is discharged into high-altitude atmosphere through a diffusing pipeline. Therefore, high negative pressure can be generated at the flange of the suction inlet of the speed-increasing section, carbon monoxide gas gathered in the hot well tank can be pumped away and discharged to the high altitude along with compressed air, and safe diffusion is realized. Meanwhile, in order to prevent negative pressure from adversely affecting the hot well tank, an air supplementing opening is also arranged on the hot well tank.
The utility model provides an utilize negative pressure to take out device of zero meter vacuum hot well jar interior toxic gas fast, characterized by: after the compressed air is accelerated through the Laval nozzle, negative pressure is generated at an inlet of an acceleration section, carbon monoxide in the hot well tank is pumped away by the negative pressure, and the carbon monoxide is prevented from being leaked to influence the personal safety of field personnel.
The above description is only for the specific embodiment of the present invention, but the structural features of the present invention are not limited thereto, and any person skilled in the art can make changes or modifications within the scope of the present invention.
