Technical field
The utility model relates to coal gasification apparatus field, specifically refers to a kind of coal gasification filtered gray water device.
Background technology
Along with the development of Chemical Engineering Technology and the adjustment of energy resource structure, for the energy resources characteristic of China's " rich coal, few oil ", coal progressively becomes the primary raw material of chemical industry.Current most hydrogen manufacturing, synthetic ammonia, MTO, MTP and SNG etc., pressurized entrained-bed Coal Gasification Technology comparatively efficient, environmental protection that its source all adopts.No matter but be coal water slurry gasification or coal gasification, in the buck of its generation, solid content is lower, and approximately 1.0～3.0wt%, and particle diameter is less, and its typical particle diameter distributes as follows: <0.25mm 90w%; <0.09mm 70w%; <0.05mm 50w%; <0.01mm 20w%; <0.005mm10w%.Traditional treatment technology all adopts by the mode of defecator gravity type natural subsidence at present, reaches after finite concentration (approximately 15～25wt%) in defecator, by vacuum belt filter, filters.Because the solid particle size in buck is little, the solid content in defecator overflow water can be higher, and therefore needing increases flocculant chemicals dosing plant, to guarantee that the solid content in defecator overflow water is less than 150wt ppm.
In this technology, because defecator adopts gravity type natural subsidence, need certain sedimentation time, so defecator volume is large, floor space is large; Slurries need be delivered to vacuum belt filter through slush pump and filter, in this system, need the moving equipment such as configuration belt drives motor, vavuum pump, fault rate is higher, and the service life of the core component filter cloth of vacuum belt filter is low, within about 2-3 month, just need to change filter cloth, not only fault rate is higher, the long-term operation that is unfavorable for gasification installation, and the maintenance cost in later stage is high.
Summary of the invention
Technical problem to be solved in the utility model be the present situation for prior art provide a kind of can long-term operation and floor space is little, substantially do not need the coal gasification filtered gray water device of later maintenance.
The utility model solves the problems of the technologies described above adopted technical scheme: this coal gasification filtered gray water device, it is characterized in that comprising container tank, described container tank bottom is provided with filtered solid outlet, the top of described container tank is provided with exhaust outlet and press filtration air inlet, the bottom of described container tank is provided with slurries entrance, the top of described container tank is provided with the slurries collection conduit that connects upstream device, is provided with many screen pipes in container tank;
Described screen pipe is closing structure, the engraved structure of the tube wall of screen pipe for only entering for liquid, and the top of screen pipe is provided with liquid outlet, and this liquid outlet is communicated with described slurries collection conduit.
In such scheme, described screen pipe can have various structures, preferably, described screen pipe can comprise the support of cell structure, on described support, be enclosed with flexible filter bag, be provided with filtrate collecting pipe in described support, the sidewall of described filtrate collecting pipe is provided with the liquid hole entering for liquid; The outlet of described filtrate collecting pipe is liquid outlet.
For the filter cake that makes to adhere on filter bag can depart from swimmingly, can on described filter bag, be coated with diatom ooze coating.By applying coating on the fiber at filter bag or braiding filter bag, improve the surface smoothness of filter bag, to be conducive to the separation of filter cake and to come off.
Consider the cheap property that filter cake departs from, can in described slurries collection conduit, also be provided with the gas access that is communicated with extraneous source of the gas.
Described container tank comprises tank body and the upper cover that is connected to tank body upper port position, and described tank body is connected by flange with upper cover.
For the discharge of raffinate in convenient container tank, can also also be provided with raffinate outlet in the bottom of described container tank.
Compared with prior art, the utility model has the advantage of compared with prior art, the utility model floor space is little, flow process is short, the water content of the rear filter cake of filtration is low, and the defecator+vacuum belt filter owing to having replaced in the application of original coal gasification tradition, has reduced investment; Meanwhile, by static equipment, replace the original moving equipment filtering, fault rate reduces, and has guaranteed the long-term operation of coal gasification.

The specific embodiment
Below in conjunction with accompanying drawing, embodiment is described in further detail the utility model.
As shown in Figures 1 to 5, this coal gasification filtered gray water device comprises:
Container tank 1, for pressure volume pot, the bottom of container tank 1 is cone structure, its bottom is provided with filtered solid outlet 11, the top of container tank is provided with exhaust outlet 12 and press filtration air inlet 13, the bottom of container tank is provided with slurries entrance 14, and the top of container tank is provided with the slurries collection conduit 15 that connects upstream device, and slurries collection conduit 15 is connected on the madial wall of container tank by support member 19.In slurries collection conduit 15, be also provided with the gas access 18 that is communicated with extraneous source of the gas; The bottom of container tank is also provided with raffinate outlet 10.
Container tank in the present embodiment is Split type structure, tank body 16 and the upper cover 17 that is connected to tank body 16 upper port positions, consists of, and tank body 16 is connected by flange 315 with upper cover 17.
Screen pipe 2, has many, is longitudinally arranged in parallel to each other in container tank 1, and for separating of the solid in buck and liquid, the liquid after separation enters in screen pipe 2, solid by backstop outside screen pipe 2.It comprises support 22, and the side perisporium of support is cell structure, is enclosed with flexible filter bag 23 on the side perisporium of support, is provided with filtrate collecting pipe 24 in support, and the sidewall of described filtrate collecting pipe 24 is provided with the liquid hole entering for liquid in collecting pipe; The outlet of described filtrate collecting pipe 24 is the liquid outlet 21 of this screen pipe.
