Raw producer gas washing, uses ratio wide in process.
But due to the fluctuation of hydrogen sulfide content in raw gas, cause the lean solution after jet regeneration can not be timely with sulfur foam
Separate；The hysteresis effect of the sulfur such as sulfur melting kettle and vacuum filter foam processing system also causes the sulfur foam in regeneration tank not simultaneously
Can deviate from time, be easily caused the problems such as desulfurization lean solution solid content raises, and desulfuration efficiency reduces, system power consumption increase.With
Time due in desulfurization lean solution solid content increase, system desulphurization reaction produce by-product increase, be further exacerbated by doctor solution
Deterioration, in system, finally form a large amount of precipitation, it has to maintenance down is cleared up, and causes greater loss.
Due in lean solution solid content increase and cause desulphurization system efficiency to reduce, the way typically taked be to increase desulfurization product
The capacity of thing collection system, to adapt to the change of the system sulfur foam growing amount that in raw gas, the change of hydrogen sulfide content causes.
But, owing to desulfurization product collection system is in desulphurization system end, and centre has multistage storage tank to buffer, and steeps at processing system sulfur
Foam is to have certain " hysteresis effect ".When sulfur foam growing amount increases sharply, it is impossible to make an immediate response, and it is lean to ultimately cause system desulfurization
The deterioration of liquid.
Summary of the invention
The technical problems to be solved in the utility model is: overcome existence when processing desulfurization foam in prior art " delayed
Effect ", increase the reactivity of desulfurization lean solution, the variable working condition disposal ability and the unit coal gas that promote whole desulphurization system process matter
Amount and efficiency.
Around above-mentioned technical problem, this utility model have employed following technical scheme:
A kind of coal gas desulfurization lean solution upgrading synergistic device, including lean liquid bath, lean liquid bath is connected with plate and frame type filter-press, sheet frame
The clear liquid outfan of formula pressure filter is connected with clear liquid groove, and clear liquid groove connects with lean liquid bath.Such scheme is i.e. set up on lean liquid bath
One road pipeline is collected to plate and frame type filter-press, the clear liquid after filter pressing by clear liquid groove, and is transmitted back to lean liquid bath.
Described lean liquid bath is connected with plate and frame type filter-press by bottom land pipeline.Increase the mouth of pipe newly at lean solution bottom land, shunt part
Bottom land lean solution is to lean liquid treating system.
Lean solution filter pump it is provided with between lean liquid bath and plate and frame type filter-press.Lean solution filter pump is set, by pending lean solution
It is delivered to high-order lean solution processing equipment.
Plate and frame type filter-press is positioned at above lean liquid bath.Arrange that high-order plate and frame type filter-press processes that lean solution filter pump sends here is thick
Lean solution.
The solid filtrate outlet side of plate and frame type filter-press is provided with hopper.Plate and frame type filter-press is placed in a high position, after filter pressing
Sulfur cream by hopper entrucking；Smart lean solution after filter pressing enters clear liquid groove by gravity flow and stores.
Clear liquid groove pipeline communication also and between lean liquid bath and plate and frame type filter-press, this pipeline is provided with clear liquid pump with clear
Liquid recycle valve.On the pipeline of clear liquid pump to lean liquid bath conveying seminal plasma liquid, clear liquid recycle valve is set, can be according to lean liquid bath
Thick lean solution result of laboratory test controls the opening and closing of clear liquid recycle valve, controls backflow clear liquid quality further.
The most discussed above, of the present utility model to realize process as follows:
Increasing the mouth of pipe newly at lean solution bottom land, shunting part bottom land lean solution is to lean liquid treating system.Shunting lean solution is by lean solution mistake
Filter pump, is delivered to high-order plate and frame type filter-press by pending lean solution.Passed through by the sulfur cream after high-order plate and frame type filter-press filter pressing
Hopper entrucking；Smart lean solution after filter pressing enters clear liquid groove by gravity flow and stores.Pipe at clear liquid pump to lean liquid bath conveying seminal plasma liquid
Lu Shang, arranges clear liquid recycle valve, can control the opening and closing of clear liquid recycle valve according to lean liquid bath thick lean solution result of laboratory test, enter one
Step controls backflow clear liquid quality.
Specific works principle of the present utility model is: when lean liquid bath lean solution result of laboratory test display solid content raises,
High-order plate and frame type filter-press and lean solution filter pump can be opened.Solid content (predominantly sulfur cream) after filtration, by under pressure filter
Sulfur melting kettle is delivered in the hopper collection of side or pack is deposited；Clear liquid after filtration passes through flow by gravity to clear liquid groove.When clear liquid groove arrives
When reaching high level, start clear liquid pump, clear liquid is delivered to lean liquid bath, completes lean solution washing and filtering operation.
When clear liquid groove result of laboratory test display clear liquid solid content raises, clear liquid pump and clear liquid recirculation can be opened simultaneously
Valve, further washing and filtering clear liquid, it is ensured that the lean solution quality of return-flow system.
