Description
Technical field
The utility model relates to a kind of cleaning device, is specifically related to a kind of honeycomb fashion mist eliminator cleaning device.
Background technology
Honeycomb fashion mist eliminator is common a kind of electrical tar precipitator, plain conductor passes from honeycomb type metal tube center, its operation principle applies high voltage direct current between plain conductor and metal pipe-wall, be enough to make gas produce the electric field of ionization to maintain, make to form corona zone between anode and cathode, electric field theory, cation is adsorbed in electronegative corona discharge electrode, and anion is adsorbed in the receiving electrode of positively charged; All negative ions be ionized all are full of the whole space between corona discharge electrode and receiving electrode.When the coal gas containing impurity such as tar droplets is by this electric field, adsorb the impurity of anion and electronics under the effect of electric field Coulomb force, institute is discharged electrically charged after moving to receiving electrode, and be adsorbed on receiving electrode, when be adsorbed in the impurity level on receiving electrode be increased to be greater than its adhesive force time, can automatically trickle downwards, discharge bottom electrical tar precipitator, pure qi (oxygen) body then leaves from electrical tar precipitator top and enters next procedure.
Electrical tar precipitator uses the reason due to impurity or temperature after a period of time, cause tar to trickle to accumulate in more slowly on metal pipe-wall, now just need to clean metal pipe-wall, traditional cleaning method adopts hot ammoniacal liquor from electrical tar precipitator top spray, after collecting, spray gets on again, scavenging period is about 1 to 2 hour, and the cycle of cleaning is about one week.Although widely use with hot ammoniacal liquor cleaning electrical tar precipitator, applicant finds that it exists following some shortcomings: that cleans comparatively frequent exactly, needs to change, waste comparatively serious after ammoniacal liquor repeatedly cleans.
Summary of the invention
The purpose of this utility model be to provide a kind of structure simple, economize on resources and the honeycomb fashion mist eliminator cleaning device of tar can be cleared up.
To achieve these goals, the utility model provides a kind of honeycomb fashion mist eliminator cleaning device, include the air inlet disk valve and air inlet blank-plate valve that are arranged on mist eliminator gas inlet in turn, be arranged on the exhaust stack of mist eliminator gas exit in turn, go out gas butterfly valve and blank-plate valve of giving vent to anger, and the coke discharging tube be arranged on bottom mist eliminator, low pressure steam pipe is provided with between described air inlet blank-plate valve and gas inlet, this low pressure steam pipe is provided with steam inlet valve, the blow-off pipe connecting coke discharging tube is provided with bottom described exhaust stack, described coke discharging tube is serially connected with a knockout drum, the import of knockout drum extend into bottom it from its top, the outlet of knockout drum is arranged on the top of tank body.
The feature of technique scheme is: owing to being provided with low pressure steam pipe between air inlet blank-plate valve and gas inlet, this low pressure steam pipe is provided with steam inlet valve, and adopt such structure to instead of traditional hot ammonia spray and EGR, structure is simpler; When needs clean honeycomb fashion mist eliminator, only need to close air inlet disk valve and air inlet blank-plate valve, go out gas butterfly valve and blank-plate valve of giving vent to anger, then coke discharging tube and exhaust stack is opened, finally open low-pressure steam inlet valve, low-pressure steam can heat the tar sticked on honeycomb fashion mist eliminator wire and metal pipe-wall, makes it soften and flows down, enter next handling process eventually through coke discharging tube; Low-pressure steam is common a kind of energy of plant area, and compared to traditional hot ammoniacal liquor, its use cost is lower.
Preferably, in order to control more easily and overhaul knockout drum, before described knockout drum import, be provided with gate valve.
Preferably, in order to control effectively to the discharge of exhaust stack, described exhaust stack is provided with electric gate valve.
Preferably, in order to reduce the cost of low-pressure steam to greatest extent, effectively utilize boiler deoxidizing method steam, described low pressure steam pipe connects boiler deoxidizing method steam simultaneously.
Accompanying drawing explanation
Fig. 1 is the main TV structure schematic diagram of the utility model embodiment.
Wherein, air inlet disk valve 1, air inlet blank-plate valve 2, goes out gas butterfly valve 3, blank-plate valve 4 of giving vent to anger, exhaust stack 5, coke discharging tube 6, low pressure steam pipe 7, steam inlet valve 8, blow-off pipe 9, knockout drum 10, gate valve 11, electric gate valve 12.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
As shown in Figure 1: the utility model embodiment provides a kind of honeycomb fashion mist eliminator cleaning device, include the air inlet disk valve 1 and air inlet blank-plate valve 2 that are arranged on mist eliminator gas inlet in turn, be arranged on the exhaust stack 5 of mist eliminator gas exit in turn, go out gas butterfly valve 3 and blank-plate valve 4 of giving vent to anger, and the coke discharging tube 6 be arranged on bottom mist eliminator, low pressure steam pipe 7 is provided with between air inlet blank-plate valve 2 and gas inlet, low pressure steam pipe 7 is provided with steam inlet valve 8, the blow-off pipe 9 connecting coke discharging tube 6 is provided with bottom exhaust stack 5, coke discharging tube 6 is serially connected with a knockout drum 10, the import of knockout drum 10 extend into bottom it from its top, the outlet of knockout drum 10 is arranged on the top of tank body, gate valve 11 is provided with before knockout drum 10 import, exhaust stack 5 is provided with electric gate valve 12, low pressure steam pipe 7 connects boiler deoxidizing method steam.
Derived energy chemical class enterprise low-pressure steam is more, and for iron and steel enterprise, it is generally provided with power plant for self-supply, and the thermal de-aeration steam comprising high-pressure boiler and preboiler is directly emptying, not only causes waste, but also brings thermal pollution.The deoxygenation steam pressure of boiler is about 0.02-0.03MPa, temperature is about 100-120 DEG C, its Application way is: when needs clean honeycomb fashion mist eliminator, only need to close air inlet disk valve 1 and air inlet blank-plate valve 2, go out gas butterfly valve 3 and blank-plate valve 4 of giving vent to anger, then coke discharging tube 6 and exhaust stack 5 is opened, finally open low-pressure steam inlet valve 8, stop after utilizing these low-pressure steams to purge about 48 hours, tar is softening to be come under the influence of gravity, discharge from coke discharging tube, the setting of knockout drum 10 can allow tar overflow from its outlet, avoids tar to reflux simultaneously.
Above-described is only preferred embodiment of the present utility model, and in scheme, the general knowledge such as known concrete structure and characteristic does not do too much description at this.Should be understood that; for a person skilled in the art, under the prerequisite not departing from the utility model structure, some distortion and improvement can also be made; these also should be considered as protection domain of the present utility model, and these all can not affect effect and the practical applicability of the utility model enforcement.
