Description
Technical field
The utility model relates to a kind of contained H in coke-oven gas that removes
2s, the equipment of the materials such as HCN and technique thereof, be specifically related to the sulfur removal technology of a kind of thionizer and thionizer.
Background technology
Traditional Structure of Flue Gas Desulfuration Absorbing and sulfur removal technology relative complex thereof, in general, thionizer comprises the thionizer main body, regenerator column, lean solution groove and rich solution groove, desulfurization process is that the raw gas of in the future self cooling bulging electric fishing workshop section enters thionizer lower body part and tower top through gas inlet and sprays the hydrogen sulfide in the doctor solution counter current contact washing absorption coal gas that gets off, the coal gas that removes hydrogen sulfide is sent to next workshop section from the tower top gas exit, the doctor solution (now also claiming rich solution) flowed out from the outlet of thionizer lower body part rich solution enters the rich solution groove, pump and enter regenerator column regeneration with solution circulation pump after supplementing the dropping catalyst solution.From the high-pressure air of high-pressure air import and rich solution by the rich solution import of regenerator column bottom and flow to into regenerator column rich solution is carried out to oxidation regeneration.Doctor solution after regeneration (now also claiming lean solution) enters the lean solution groove from the outlet of regenerator column tower top lean solution, pumps by the lean solution import and enters the desulfurization of thionizer main body tower top spray with solution circulation pump afterwards.The sulphur foam that the regenerator column tower top floatingly selects, from the sulphur foam outlet flows out tower, is sold outside processing sulphur.
Traditional sulfur removal technology has following some weak point:
The one, complex structure, whole desulphurization system main equipment quantity is many, as more than thionizer main diameter φ 5000mm, more than regenerator column diameter phi 4000mm, more than height 40m, also has some large diameter groove tanks etc.Build the ground area large, the wide distance of piping arrangement, increased equipment investment cost.
The 2nd, complex process, the rich solution oxidation regeneration is to adopt the high tower reclaiming process, must build separately regenerator column, rich solution groove and lean solution groove; And the regenerator column column internals adopts the carbon steel material sieve tray, low, the easy obstruction of erosion resistance, duration of service is short, the equipment parking maintenance is frequent, thereby makes the normal operation of system and the increasing of line service difficulty.
The 3rd, because equipment volume is large, type kind is many, the pipelining distance, the various losses in making to produce all increase, and as the loss of calorific loss, catalyzer, caused desulfuration efficiency decline, increased running cost, reduced efficiency.From above some can find out that traditional sulfur removal technology exists problems and shortcoming.
The utility model content
The utility model purpose is exactly that a kind of coke oven gas desulfurization novel process and new installation that can effectively overcome above-mentioned shortcoming, address the above problem will be provided, to reduce the highly efficient regeneration thionizer of facility investment, simplification production process, the energy consumption that reduces, raising desulfuration efficiency.
