Problems solved by technology

[0011] In order to solve the difficulty in adjusting the pressure due to large fluctuations in the composition of the converter gas in the prior art, a single adjustment method has been unable to cope with the fluctuations in the composition of the converter gas, resulting in unstable quality of the lime produced by the kiln. The problem that the normal calcination and smooth operation of the kiln with coal gas as fuel has a great influence. The invention provides a gas pressurization device and a gas pressurization control method for the kiln gas, which can be automatically adjusted to enter the kiln during production. The pressure of the converter gas in front of the mouth ensures that the gas pressure and flow are stable and controlled. By implementing this invention, the quality of lime produced by the kiln can be effectively stabilized. A gas pressurization device and gas pressurization control for kiln gas of the present invention Method, its concrete structure and method steps are as follows:

Abstract

The invention discloses a coal gas pressing device and a coal gas pressing control method for a furnace kiln coal gas. The coal gas pressing device comprises a coal gas pressing machine, wherein the coal gas pressing machine is provided with a frequency converter assembly; a stable pressure of the coal gas pressing machine is maintained through variable-frequency speed adjustment of the frequency converter assembly; one end of a backflow valve assembly is communicated to a gas channel between a coal gas inlet valve and a converter coal gas supply pocket; the other end of the backflow valve assembly communicates with a gas channel between a coal gas outlet valve and a furnace kiln system; a coal gas inlet pressure detection device is arranged on the gas channel communicating with the coal gas inlet valve, of the backflow valve assembly; and a coal gas outlet pressure detection device is arranged on the gas channel communicating with the coal gas outlet valve, of the backflow valve assembly. The device part disclosed by the invention is reasonable in structure and easy to implement; and a closed-loop adjustment control system is adopted in the method part, the pressure of a converter coal gas before entering a furnace kiln is subjected to pressing adjustment to meet the fuel requirements of the furnace kiln, heat in the kiln is stably controlled, the quality indexes of lime production can meet the need of steel making, and remarkable effects of energy conservation and emission reduction are achieved.

Description

technical field [0001] The invention relates to a pressure control device and a pressure control method, in particular to a device and a gas pressurization control method for pressurizing kiln gas in the converter steelmaking production process. Background technique [0002] At present, in the production process of converter steelmaking in the field of iron and steel production, a large amount of flue gas will be produced. The main component of this flue gas is coal gas, that is, CO, accounting for about 60% to 75% of the total, followed by carbon dioxide CO2 and Nitrogen N2, while the content of other gases contained in the flue gas is very small, almost negligible, so the converter flue gas is usually called converter gas. [0003] Converter gas is a poisonous, harmful, flammable, explosive and dangerous gas. It is also a good energy source for industrial production. In the past, almost all units had a surplus of converter gas, which had to be released in large quantities....
