Description

Ou ye stove oxygen wind gap jetting coal gas drainage monitoring devices

Technical Field

The utility model relates to an Ou smelt stove oxygen wind gap jetting coal gas drainage monitoring devices.

Background

The European furnace is the only domestic smelting reduction furnace which is not used for blast furnace iron making and is in production operation.

The Ou metallurgical furnace injects coal gas through the tuyere, so that the coal gas can be recycled, the external diffusion of redundant coal gas is reduced, the environment is improved, and the aims of energy conservation and emission reduction are fulfilled. The process flow is as follows: after low-pressure coal gas (containing water) is pressurized by a compressor, the pressure of the coal gas rises, simultaneously, coal gas water is separated out in the pressurizing process, the coal gas water is discharged through a water outlet of the compressor, and then the dehydrated high-pressure coal gas is conveyed to a tuyere through a coal gas pipeline and is blown into a furnace through a tuyere small sleeve.

When the compressor has drainage fault, the gas water enters the gas pipeline along with the high-pressure gas and is delivered to the air port along the gas pipeline, and then is blown into the furnace. The gas water is quickly vaporized in the high-temperature environment in the furnace and absorbs a large amount of heat, so that the heat balance of smelting in the furnace is damaged, and the production operation is extremely unstable. However, the problem of water content in the coal gas caused by the drainage fault of the compressor is difficult to find in time, and the drainage fault of the compressor is often found, so that the production is seriously influenced. In order to find the problem of water content in the high-pressure gas in time and reduce the influence on the stable production operation, a device which can detect whether the high-pressure gas contains gas water in time on line and can discharge the gas water out of a gas pipeline is needed to be designed.

From patent retrieval, a keyword 'coal gas injection' is retrieved, and a patent 'a coal gas injection device of an iron-making blast furnace' is retrieved, wherein the inventor: luciola pratensis, etc.; relates to a coal gas injection device of an iron-making blast furnace, a device for adjusting a coal gas inlet device and preventing hot air from flowing backwards; the keyword of 'Ou smelt furnace coal gas injection' is searched, and the utility model patent 'improved Ou smelt furnace coal gas injection furnace' (CN207316903U) is searched. The inventor: the book is Jishuming. The patent abstract comprises the following steps: a horizontal type coal gas injection furnace structure of an Ou metallurgical furnace is a combustion heating furnace.

The similar patents are different from the detection environment and conditions of the gas injected from the tuyere of the European and metallurgical furnace, and do not meet the requirements of field leak detection and drainage after the tuyere of the European and metallurgical furnace injects the gas.

Disclosure of Invention

An object of the utility model is to provide an Ou smelt stove oxygen wind gap jetting coal gas drainage monitoring devices can realize judging and automatic drainage to the effective inspection after jetting coal gas ponding.

Realize the utility model discloses a european smelting stove oxygen wind gap jetting coal gas drainage monitoring devices of purpose, sealed staving that is setting up the vexed board flange on a top surface and the bottom surface respectively, setting up the window flange on the lateral wall of staving, the window flange is sealed to be setting up glass panels, vertical downward interlude has an intake pipe on the staving top surface that is close to glass panels, is setting up the drain valve on the staving bottom surface of intake pipe below, and vertical upwards interlude is setting up an outlet duct on the staving bottom surface of drain valve side, and wherein the upper end mouth of pipe position of outlet duct is highly higher than the lower extreme mouth of pipe position height of intake pipe.

The utility model discloses can effectual on-line measuring judge the inside ponding state after sneaking into mechanical water of oxygen tuyere small envelope gas injection pipeline to utilize speed difference and kinetic energy poor, and density difference, the ponding of discharging through ponding, drainage device, realize pipeline normal operating.
