Description
Technical field
The invention belongs to tail gas disposal technique field, has been provided in particular in a kind of coking desulfurization regenerator exhaust treatment system
Pipeline.
Background technology
Domestic many coal chemical enterprises use Wet-type oxidation sweetening technique at present, and the regeneration supporting with it uses regenerator work
Skill, reduced investment is characterized in, regeneration efficiency is high, and tail gas is directly discharged into air by way of high altitude discharge at the top of its regenerator.
But the tail gas amount of this regenerator is larger, the impurity component in tail gas is more complicated (mainly containing NH3、H2S, VOCs etc.), its content
Also higher, intractability is larger.There is part coal chemical enterprise to absorb the NH in tail gas respectively using the method for multistage absorption3、H2S、
After the pollutant components such as VOCs, by the processing method of exhaust emissions air, but, operating cost uneven in the prevalence of absorption efficiency
Height, the problems such as execute-in-place complexity.And it is increasingly strict with national environmental protection regulation, the requirement to pollutant emission limit is also got over
Come higher, this just proposes higher requirement for the processing of regenerator tail gas.
The content of the invention
Object of the present invention is to provide a kind of coking desulfurization regenerator exhaust treatment system pipeline, solve and generally deposit
Uneven in absorption efficiency, operating cost is high, the problems such as execute-in-place complexity；By gas pipe before regenerator tail gas introducing air blower
Coke-stove gas in road, with pipeline is together handled, and is accomplished that regenerator tail gas is not completely outer and is arranged.
The present invention includes regenerator 1, diffuse channel 2, the first rapidly opened and closed valve 3, connecting pipe 4, the second rapidly opened and closed valve
5th, gas-blowing engine 6, oxygen conten analyser 7, gas piping 9 after gas piping 8, air blower before air blower.Regenerator 1 passes through company
Thread a pipe and 4 connected with gas piping before air blower 8, diffuse channel 2 connects with connecting pipe 4, and gas-blowing engine 6 connects air blower
Preceding gas piping 8 and gas piping 9 after air blower；First rapidly opened and closed valve 3 is arranged on diffuse channel 2, and second is rapidly opened and closed
Valve 5 is arranged on connecting pipe 4, and oxygen conten analyser 7 is connected with gas piping after air blower 9.The discharge of the top of regenerator 1 is again
Raw tower tail gas, by connecting pipe 4 into gas piping 8 before air blower, is mixed with the coke-stove gas introduced by gas piping 8
Afterwards, the gas piping 9 after the pressurization of gas-blowing engine 6 enters air blower.
Connecting pipe 4 is provided with tracing thermal-insulating, and its heat tracing form is steam tracing or electric tracing.
The invention provides a kind of coking desulfurization regenerator exhaust treatment system pipeline, and regenerator tail gas is introduced into air blower
Preceding coke oven gas pipe, together handled with coke-stove gas, air is not discharged, thoroughly solve coal chemical enterprise Wet-type oxidation sweetening
Pollution problem of the tail gas to air, has the advantages that simple in construction, easy to use, environmental benefit is good at the top of technique regenerator.
Brief description of the drawings
Fig. 1 is coking desulfurization regenerator exhaust treatment system pipeline configuration schematic diagram.Wherein：Regenerator 1, diffuse channel 2,
First rapidly opened and closed valve 3, connecting pipe 4, the second rapidly opened and closed valve 5, gas-blowing engine 6, oxygen conten analyser 7, before air blower
Gas piping 9 after gas piping 8, air blower.
Embodiment
The present invention includes regenerator 1, diffuse channel 2, the first rapidly opened and closed valve 3, connecting pipe 4, the second rapidly opened and closed valve
5th, gas-blowing engine 6, oxygen conten analyser 7, gas piping 9 after gas piping 8, air blower before air blower.Regenerator 1 passes through company
Thread a pipe and 4 connected with gas piping before air blower 8, diffuse channel 2 connects with connecting pipe 4, and gas-blowing engine 6 connects air blower
Preceding gas piping 8 and gas piping 9 after air blower；First rapidly opened and closed valve 3 is arranged on diffuse channel 2, and second is rapidly opened and closed
Valve 5 is arranged on connecting pipe 4, and oxygen conten analyser 7 is connected with gas piping after air blower 9.The discharge of the top of regenerator 1 is again
Raw tower tail gas, by connecting pipe 4 into gas piping 8 before air blower, is mixed with the coke-stove gas introduced by gas piping 8
Afterwards, the gas piping 9 after the pressurization of gas-blowing engine 6 enters air blower.
Connecting pipe 4 is provided with tracing thermal-insulating, and its heat tracing form is steam tracing or electric tracing.
As shown in figure 1, the regenerator tail gas of the top of regenerator 1 discharge, passes through gas pipe before the entrance air blower of connecting pipe 4
Road 8, after being mixed with the coke-stove gas introduced by gas piping 8, the gas piping after the pressurization of gas-blowing engine 6 enters air blower
9。
