Abstract

The invention relates to the field of application of calcium carbide furnace tail gas in lime burning, and particularly relates to a connecting adjustment device of a double-hearth lime kiln burning the calcium carbide furnace tail gas. The connecting adjustment device comprises a calcium carbide furnace tail gas pipeline, a coal gas pressing machine and a low-pressure main pipe, wherein the calcium carbide furnace tail gas pipeline is connected to a gas outlet of a calcium carbide furnace, the coal gas pressing machine is connected to the double-hearth lime kiln through a high-pressure main pipe, and the low-pressure main pipe is connected to a gas inlet of the coal gas pressing machine and is communicated with the calcium carbide furnace tail gas pipeline; and the connecting adjustment device also comprises a first set of adjustment device and a second set of adjustment devices, wherein the first set of adjustment device comprises a first diffusion pipeline, a pneumatic control valve, a first tempering prevention device and a first flame combustor, the first diffusion pipeline is communicated with the low-pressure main pipe, the pneumatic control valve and the first tempering prevention device are arranged on the first diffusion pipeline from bottom to top, the first flame combustor is arranged at the end part of the first diffusion pipeline, and a first electronic burning torch and a first flame detectors are arranged in the first flame combustor.

Description

technical field [0001] The invention relates to the field of calcium carbide furnace tail gas used for calcining lime, in particular to a connection adjustment device for calcium carbide furnace tail gas used in a gas-fired double-chamber lime kiln. Background technique [0002] Judging from the existing double-chamber lime kiln 1 using calcium carbide furnace tail gas to calcinate lime, generally the calcium carbide furnace tail gas pipeline 3 of the calcium carbide furnace 2 is connected to the gas tank 4, and the gas tank 4 is connected to the gas tank through the low-pressure main pipe 5. On the press 6, the double-chamber lime kiln 1 and the gas press 6 are connected through a high-pressure main pipe 7 . [0003] Utilizing the gas holder 4 to recycle tail gas to calcine lime is currently a commonly used method, because the tail gas usually has unstable pressure during the upstream process (between the calcium carbide furnace 2 and the double-chamber lime kil...
