A coke oven gas flow regulating device that can be precisely adjusted

Abstract

The invention relates to a coke oven gas flow regulator capable of accurate regulation, which comprises a hexagonal regulating block, a T joint A, a cross joint, a locking nut, a regulating slipknot device, a pressure meter, a bent tube, a valve, a transverse tube extending tube, a heating transverse tube, a T joint B, a regulating pinhole plate, a seal ring, a miter valve core and a gas inlet tube, wherein two ports of the cross joint in the vertical direction are respectively connected with branch tubes of the T joint A; the T joint A is connected with one end of the regulating slipknot device through the end surface of the locking nut; the regulating pinhole plate with through holes is arranged in the slipknot of the regulating slipknot device; the miter valve core is arranged in the main tube of the T joint A; and both ends of the miter valve core are respectively a thread regulating end and a cone seal end. The coke oven gas flow regulator has the advantages of simple structure, accurate regulation and no leakage, can be always kept in the smooth state by using the double miter valve regulation mechanism, and is convenient for overhaul.

Description

technical field [0001] The invention relates to the field of coke oven equipment, in particular to a precisely adjustable coke oven gas flow regulating device. Background technique [0002] At present, in the production of the metallurgical industry, coke ovens are heated by means of coke oven gas heating. Among them, the adjustment of the coke oven horizontal row temperature generally adopts the theoretical sequence of orifice plates. In terms of the arrangement order of the orifice plates, during the treatment process, the heating gas purification effect is better, and the pipeline resistance is small and unimpeded. This arrangement has certain benefits for the furnace temperature adjustment and is more suitable. [0003] In actual production, due to the poor quality of gas purification, after a period of heating in the heating system, the corrosive gas in the gas will corrode the small orifice plates of the gas, resulting in the loss of meaning of the horizontal orifice p...

Problems solved by technology

[0003] In actual production, due to the poor quality of gas purification, after a period of heating in the heating system, the corrosive gas in the gas will corrode the small orifice plates of the gas, resulting in the loss of meaning of the horizontal orifice plates arranged regularly. The furnace temperature may be controlled for a long time when the small orifice plate needs to be replaced, but the coking time does not change, which may affect the coke quality

In actual operation, the gas flow is often adjusted by adding a stick or iron wire. Although it is effective, the adjustment is relatively rough due to the fixed diameter of the stick or iron wire.
