And condensation-water drain.The structure and annexation of remainder and the structure described in any previous embodiment and annexation phase
Together.2
In view of above-described embodiment, when in use, its course of work and principle are as follows by the application：
Coal gas from previous process is entered in desulfurizing tower 1 by the coal gas inlet pipe positioned at the bottom of desulfurizing tower 1.Because coal
The characteristic of gas itself, the coal gas entered in desulfurizing tower 1 can rise along desulfurizing tower.And coal gas is provided with the top of desulfurizing tower
Outlet, by being contacted with doctor solution from bottom to top reverse, the coal gas by desulfurization enters big next work through gas outlet tube
Sequence.
Desulfurizing tower liquid inlet tube on desulfurizing tower 1 is located at the top of desulfurizing tower, and it is used to desulfurizing agent being sprayed into desulfurizing tower 1
In, fully contacted with the coal gas run from bottom to top so as to realize that the desulfurizing agent from lean liquid tank 4 flows from top to bottom, complete coal
The desulfurization of gas.The desulfurizing agent that desulfurization is completed flows out to desulfurizing tower liquid seal trough 2 by the desulfurizing tower liquid outlet of the bottom of desulfurizing tower 1.
Containing higher hydrogen sulfide, hydrogen cyanide in desulfurizing agent now, may proceed to enter after entering desulfurizing tower liquid seal trough 2
To rich solution groove 6, the doctor solution in rich solution groove 6 can be pumped to jet regeneration tower 8 by rich solution pump 7, realize real in jet regeneration tower 8
The regeneration of existing doctor solution.Flowed automatically to after desulfurization regeneration after being removed positioned at the liquid level regulator at the top of jet regeneration tower 8 poor
Liquid bath 4, and the lean pump 5 for continuing through the connection of lean liquid tank 4 realizes the sprinkling desulfuration operations to coal gas.
Sulphur foam tank 9 is flowed automatically to after the sulphur foam of the top enlarged of jet regeneration tower 8, spilling.In sulphur foam tank 9
It is driven into after stirring fully through sulphur foam pump 10 in sulfur melting kettle 11.Pass through thermal dehydration, the clear liquid of sub-department in sulfur melting kettle 11
It is discharged in follow-up accident groove, is used to dissolve soda ash after cooling.Sulphur foam continues to be heated to sulfur melting in sulfur melting kettle 11, protects
Warehouse is sent into cooling packing after warm a period of time.
In order to ensure the efficiency of desulfurization, also increase has catalyst storage tank 3 in the utility model, and catalyst storage tank 3 is used for
Catalyst is sent into lean liquid tank 4, realizes the mixing with desulfurizing agent in lean liquid tank 4, is promoted in desulfurizing agent and coal gas contact process
Desulfurized effect.The dissolving that the import of boiler soft water is used to promote catalyst is also connected with catalyst storage tank 3, and temperature is kept
At 60~90 DEG C, soak time is controlled in 3~4h.
It should be noted that in the utility model, when coal gas enters 1 inside of desulfurizing tower, its temperature is needed for 30~40
DEG C, the temperature of desulfurizing agent is higher than 3~5 DEG C of gas temperature, if temperature is relatively low when coal gas enters tower, can cause reaction speed compared with
Slowly, if temperature on the contrary is higher, then the speed of side reaction can be increased.And desulfurizing agent can higher than in the range of 3~5 DEG C of gas temperature
The water balance of holding system, especially in the case where that need not extract sodium sulfocyanate, the temperature difference is particularly necessary.In desulfurizing tower
Pressure need to maintain in the process of running less than in the range of 100mm water columns, to ensure the safety of equipment.
Because in desulfuration operations, hydrogen sulfide or hydrogen cyanide have certain corrosiveness, if the PH in desulfurizing tower is small
In 8.5, then reaction speed can be caused slack-off, and the reaction speed of side reaction can be increased if PH is too high, and the consumption of alkali
Also it can increase, so that speed of separating out of the desulfurization in desulfurizing tower is speeded, easily cause the blocking of desulfurizing tower, therefore this practicality
PH in new middle selective sweetening tower is maintained in 8.5~9.1 rational ranges of operation.
Using the said equipment, the emission concentration of hydrogen sulfide in coke gas is 10mg/m3, using temperature as 273.15K, pressure
For 101325Pa when in the state of coke-stove gas total emission volumn be 2.4 hundred million m3/ a is calculated, SO2Year, total CER was 278t, organic
The CER of sulphur is 237.3t.
