It should be noted that the noun of locality in the present embodiment is upper and lower, it is with the coke-stove gas gas transmission system shown in Fig. 2
It is defined on the basis of position.
Refer to Fig. 1, a kind of coke oven gas purification system that the present embodiment is provided, including：Coke-stove gas gas transmission system
00th, coke oven 01 and purifier 02.
Wherein, the inlet end of coke-stove gas gas transmission system 00 is connected with coke oven 01, the outlet of coke-stove gas gas transmission system 00
End is connected with purifier 02.
Incorporated by reference to Fig. 2 and Fig. 3, the coke-stove gas gas transmission system 00 includes：Appendix 1, spray equipment 2, screeding device 3,
Collecting box 4 and baffle plate 5.
Wherein, appendix 1 is used to connect to be provided with fuel-displaced cinder notch on coke oven 01 and purifier 02, and appendix 1；Spray
In device 2, the inlet end for being arranged at appendix 1, for spraying liquid to the raw coke oven gas entered in appendix 1；Screeding device 3,
It is installed in appendix 1, the tar slag in appendix 1 is deposited on for scraping delivery；Baffle plate 5, is installed on appendix 1, for blocking
The gas on the top of appendix 1 is simultaneously reserved for the breach that the tar slag is scraped.
Preferably, the coke-stove gas gas transmission system 00 also includes collecting box 4, is installed at the fuel-displaced cinder notch of appendix 1, uses
In collection tar slag.
In actual applications, after the raw coke oven gas that coke oven 01 is produced is by the coke-stove gas gas transmission system 00, into purification dress
2 are set to 0 to be purified.In the process, the spray equipment 2 of the inlet end of appendix 1 is arranged on first to entering the waste coal in appendix 1
Liquid is spilt in gas blowout, and the liquid of sprinkling causes the temperature of raw coke oven gas to reduce, and then so that the big portion entered with raw coke oven gas in appendix 1
The washing that is condensed of the impurity such as point dust is got off, for example, it is assumed that continuously being sprayed to raw coke oven gas using cyclic ammonia water, is circulating ammonia
After water sprinkling, the temperature of raw coke oven gas can be down to 82 ° from 650 °.Afterwards, the impurity such as the dust washed enter appendix 1
Interior, sedimentation forms tar slag.Then, screeding device 3 by the tar slag scraping delivery of deposition into collecting box 4.
To ensure that raw coke oven gas is not revealed from the fuel-displaced cinder notch of appendix 1, baffle plate is installed at the fuel-displaced cinder notch of appendix 1
The breach of tar slag outflow is reserved between 5, and baffle plate 5 and appendix 1, so that tar slag can flow out from fuel-displaced cinder notch.
For example, to ensure that baffle plate 5 seals effective to the gear of raw coke oven gas, baffle plate 5 can be inserted at least 40mm in the liquid in appendix 1, but
It is that bottom of the baffle plate 5 not with appendix 1 is connected.
Dust in the scheme provided by the embodiment of the present invention, the raw coke oven gas that can produce coke oven 01 is by this
Removed during coke-stove gas gas transmission system 00, it is to avoid dust enters purifier 02 with raw coke oven gas, causes purifier 02
