Embodiment 1

[0039] see figure 1 , the present invention is used for the boiler gas inlet system of semi-coke tail gas and calcium carbide tail gas, and it comprises calcium carbide tail gas inlet pipe 1, semi-coke tail gas inlet pipe 2, gas cabinet 3, the first mixed gas inlet pipe 41, the second mixed gas inlet pipe Gas pipe 42, liquid seal structure 5, water seal ammonia pool 6, mixed gas ammonia water discharge pipe 7, burner group intake pipe 10, burner group 11 and mixed gas release pipe 12; liquid seal structure 5 includes liquid seal box, liquid seal Structural intake pipe 51, liquid seal structure outlet pipe 52, liquid seal structure overflow pipe 53, liquid seal structure liquid injection pipe 55 and liquid seal structure discharge pipe 54; The air inlet of the cabinet 3 is connected, the gas cabinet 3 is connected with a cooling tower, the cooling tower is used to cool the mixed gas in the gas cabinet 3, the first mixed gas inlet pipe 41 is connected with the gas outlet of the ...

Embodiment 2

[0042] The boiler gas intake system for semi-coke tail gas and calcium carbide tail gas realizes the boiler gas intake process for semi-coke tail gas and calcium carbide tail gas in the present embodiment 1, and its step is that semi-coke tail gas and calcium carbide tail gas enter gas cabinet 3 respectively, Perform pressure balance, cooling and mixing in the gas cabinet 3 to form a mixed gas; the mixed gas enters the first mixed gas inlet pipe 41 after being discharged from the gas cabinet 3, and enters the liquid in the liquid seal box through the first mixed gas inlet pipe 41. Liquid seal, in which impurities such as coal tar, moisture, and ammonia in the mixed gas are cleaned, and then the mixed gas is discharged from the liquid seal box and enters the second mixed gas inlet pipe 42; the liquid seal in the liquid seal box The liquid is always in a state of dynamic equilibrium when the liquid inlet is continuously fed in and the liquid-sealed structure overflow pipe 53 is c...

Abstract

The invention provides a boiler gas intake system and process for semi-coke tail gas and calcium carbide tail gas, and belongs to the technical field of boiler combustion systems and processes. The system comprises a calcium carbide tail gas intake pipe, a semi-coke tail gas intake pipe, a first mixed gas intake pipe, a second mixed gas intake pipe, a liquid seal structure, a burner set gas intake pipe and a burner set; and the calcium carbide tail gas intake pipe and the semi-coke tail gas intake pipe are both communicated with the first mixed gas intake pipe, the burner set is communicated with the burner set gas intake pipe, and the burner set gas intake pipe is communicated with the second mixed gas intake pipe. According to the boiler gas intake system for the semi-coke tail gas and the calcium carbide tail gas, it is ensured that mixed gas can be cleaned up, and the conveying resistance of a conveying pipeline is reduced.

Description

technical field [0001] The invention belongs to the technical field of boiler combustion systems and processes, in particular to a boiler gas intake system and intake process for semi-coke tail gas and calcium carbide tail gas. Background technique [0002] At present, common boilers generally only burn a single exhaust gas such as semi-coke exhaust gas or calcium carbide exhaust gas, and then transport the single semi-coke exhaust gas or calcium carbide exhaust gas to the boiler burner for combustion through a booster fan. For factories that produce both calcium carbide and semi-coke, two gases will be produced: calcium carbide tail gas and semi-coke tail gas. Semi-coke tail gas and calcium carbide tail gas contain a large amount of combustible gas, and the calorific value is also very high. If the semi-coke tail gas and calcium carbide tail gas are directly processed It wastes energy and increases processing costs. Therefore, the general practice is to mix semi-coke tail ...
