Abstract
The utility model provides a negative pressure oil tar ammonia water adding and spraying system with a JNDK43-03F type coke oven and relates to an ammonia water adding and spraying system with a coke oven, and the system is used for solving the problems existing in the negative pressure system of the JNDK43-03F type coke oven that when the pressure of coal gas discharged from the oven fluctuates, the water level of the oil tar cannot fulfill a sealing effect, and air is sucked to cause a phenomenon that the oxygen content of the coal gas exceeds the standards, and the methyl alcohol production is influenced. The two ends of the oil tar box are respectively communicated with a negative pressure pipeline and a gas collecting pipe; one end of a U-shaped elbow pipe is communicated with a negative pressure pipeline, and the other end of the U-shaped elbow pipe is communicated with the gas collecting pipe; the output end of a main ammonia water pipeline is communicated with the U-shaped elbow pipe; one end of an auxiliary ammonia water pipeline is communicated with the pressure end of the main ammonia water pipeline, and the other end of the auxiliary ammonia water pipeline is communicated with the oil tar box; an auxiliary pipeline valve is arranged on the input end of the auxiliary ammonia water pipeline; one ends of branching pipes are communicated with the auxiliary ammonia water pipeline, and the other ends of the branching pipes are communicated with a negative pressure pipeline through a cleaning hole; and a branching pipe valve is arranged on each branching pipe. The negative pressure oil tar ammonia water addition spraying system is used for spraying ammonia water of the JNDK43-03F type coke oven.
Description
Technical field
The utility model relates to a kind of coke oven and adds the ammoniacal liquor sprinkling system.
Background technology
Existing JNDK43-03F Formed Coke Furnace negative pressure system tar box adopts the interior ammoniacal liquor of effuser from being pressed onto in the tar box.Because blower fan suction is connected effuser with each negative-pressure pipeline, the raw gas of coming out of the stove separates by convergeing to of negative-pressure pipeline product through cyclic ammonia water washing cooling, three coke oven multiple spot effuser suction are adjusted, (especially use high pressure aqua ammonia to lead fume and dust) when the discharged producer gas pressure surge, the total suction of blower fan is certain, various places coal gas suction changes, can cause coke oven negative pressure tar box water seal level fluctuation, when negative pressure tar box water level does not reach the fluid-tight effect, can cause the coal gas oxygen level to exceed standard by air amount, affect methanol production.
The utility model content
The purpose of this utility model is for solving JNDK43-03F Formed Coke Furnace negative pressure system tar box, when the discharged producer gas pressure surge, tar box water level does not reach the fluid-tight effect, can cause the coal gas oxygen level to exceed standard by air amount, affect the problem of methanol production, provide a kind of JNDK43-03F Formed Coke Furnace negative pressure tar to add the ammoniacal liquor sprinkling system.
the utility model comprises negative-pressure pipeline, the ammoniacal liquor main pipe line, U-shaped bend pipe, effuser, the tar box, the auxiliary pipeline of ammoniacal liquor, auxiliary pipeline valve, several take-off pipes and several take-off pipe valves, described tar box is arranged between negative-pressure pipeline and effuser, and the two ends of tar box are communicated with negative-pressure pipeline and effuser respectively, one end of described U-shaped bend pipe is communicated with negative-pressure pipeline, the other end of described U-shaped bend pipe is communicated with effuser, the output terminal of described ammoniacal liquor main pipe line is communicated with U-shaped bend pipe, one end of the auxiliary pipeline of described ammoniacal liquor is communicated with the end of suppressing of ammoniacal liquor main pipe line, the other end of the auxiliary pipeline of described ammoniacal liquor passes in the tar box, auxiliary pipeline valve is arranged on the input end of the auxiliary pipeline of ammoniacal liquor, each clean-out opening place at negative-pressure pipeline arranges a take-off pipe, and an end of take-off pipe and the auxiliary pipeline communication of ammoniacal liquor, the other end of take-off pipe is passed in negative-pressure pipeline by clean-out opening, a take-off pipe valve is installed on each take-off pipe.
The utility model has the advantages that: one, the utility model arranges along negative-pressure pipeline the auxiliary pipeline of ammoniacal liquor to tar box place, open auxiliary pipeline valve and directly inject ammoniacal liquor in the tar box, guaranteed tar box water seal liquid level, prevent the raw gas air amount, avoid the coal gas oxygen level to exceed standard, guarantee methanol production steady running.Two, the utility model can reduce the waste of the energy, has improved the Chemicals production yield rate, has reduced environmental pollution, has protected the employee healthy, has extended coke oven work-ing life.
