Abstract
The utility model provides an alkaline washing tower for acidic gas drip washing, wherein an alkaline washing liquor storage tank is arranged at the lower part of a tower body, while a drip washing region is defined at the upper part of the tower body; an impurity inlet is formed on the side wall of the lower end of the drip washing region; a medium outlet and a spraying opening are formed on the upper end part of the drip washing region; the alkaline washing liquor storage tank is communicated with the spraying opening through a pipeline; a liquor delivery pump for conveying the liquor is arranged in the pipeline. The alkaline washing tower for acidic gas drip washing is characterized in that the alkaline washing liquor storage tank is further provided with a heating coil which is communicated with an external steam pipeline, and a steam valve is arranged on the air inlet of the heating coilThe alkaline washing tower for acidic gas drip washing has the advantages that the steam valve for heating the alkaline liquor is slowly opened by 1/4-1/3 so that steam slowly heats the alkaline liquor, and the temperature of the alkaline liquor is also correspondingly increased at the same time, and (2-2.5) hours later, crystals in the alkaline washing system are melted and blockage is eliminated completely. The alkaline washing tower for acidic gas drip washing provided by the utility model is simple in structure, convenient to operate and ideal in blockage elimination effect.
Description
Technical field
The utility model relates to the device of caustic washing system block clearing, particularly a kind of sulfur hexafluoride is produced can automatic block clearing caustic wash tower.
Background technology
The device of the existing caustic wash tower for sour gas drip washing, its device is mainly a caustic wash tower, and the material of tower is carbon steel plastics.Tower divides two joints, and upper joint is tower body, is gas-liquid drip washing region, laid inside filler; Lower joint is tower seat, is the storage area of alkali lye.Magnetic drive pump is delivered to alkali lye the mouth spray on tower body top, absorption liquid from upper spray and under.With sour gas such as hydrogen fluoride, from medium import, enter caustic wash tower, under the spray of absorption liquid, the sour gas such as hydrogen fluoride are absorbed.
There is following defect in this method: with the rough sulfur hexafluoride gas of the sour gas such as hydrogen fluoride, carries sulfur dioxide (SO2) and vikane (SOF2 secretly, SO2F2), these materials can react with alkali lye, generate sulphur simple substance, the easy crystallization of sulphur simple substance, thus cause pipeline and mouth spray to stop up, and caustic wash tower inner stuffing condenses, cause alkali lye to flow not smooth, so produce after a period of time, with regard to stopping, it is carried out block clearing and changes filler.
Utility model content
The purpose of this utility model is in order to overcome above-mentioned the deficiencies in the prior art, provide that a kind of sulfur hexafluoride produces can automatic block clearing caustic wash tower.
To achieve these goals, the technical solution adopted in the utility model is:
A kind of caustic wash tower for sour gas drip washing, tower body bottom is alkali wash water liquid reserve tank, top is drip washing district, described drip washing district lower end sidewall is provided with medium import, upper end, drip washing district is provided with media outlet and mouth spray, the liquid-feeding pump that described alkali wash water liquid reserve tank is connected with mouth spray by pipeline and is provided for infusing in pipeline, it is characterized in that, described alkali wash water liquid reserve tank is further provided with heat(ing) coil, described heat(ing) coil is connected with external steam pipeline, and described heat(ing) coil air inlet is provided with steam valve.
In order to realize the control that more has automation, the utility model further improves, also include controller and temperature sensor, described steam valve is magnetic valve, described temperature sensor is arranged in alkali wash water liquid reserve tank, and described controller connects described steam valve and temperature sensor and controls steam valve switch.
Wherein, the wall of described alkali wash water liquid reserve tank is provided with airtight transparency window, in described airtight transparency window, is provided with thermometer.
Wherein, described steam valve is magnetic valve.
Wherein, described liquid-feeding pump is magnetic drive pump.
The beneficial effects of the utility model are: the steam valve for alkali lye is heated is slowly opened into (1/4-1/3) aperture, and steam slowly heats alkali lye, now also corresponding rising of the temperature of alkali lye.(2-2.5) hour, the crystallization in caustic washing system is dissolved, and block clearing is complete.The utility model is simple in structure for the caustic wash tower of sour gas drip washing, simple operation and block clearing satisfactory for result.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model caustic wash tower;
Wherein,
1: alkali wash water liquid reserve tank; 11: heat(ing) coil; 12: steam valve;
2: drip washing district; 21: medium import; 22: media outlet; 23: mouth spray;
3, pipeline; 31: liquid-feeding pump.
The specific embodiment
By describing technology contents of the present utility model, structural feature in detail, being realized object and effect, below in conjunction with embodiment and coordinate accompanying drawing to be explained in detail.
See also Fig. 1, a kind of caustic wash tower for sour gas drip washing of the utility model, tower body bottom is alkali wash water liquid reserve tank 1, top is drip washing district 2, described drip washing district 2 lower end sidewalls are provided with medium import 21, 2 upper ends, drip washing district are provided with media outlet 22 and mouth spray 23, the liquid-feeding pump 31 that described alkali wash water liquid reserve tank 1 is connected with mouth spray 23 by pipeline 3 and is provided for infusing in pipeline, described liquid-feeding pump 31 is water pump or magnetic drive pump, described alkali wash water liquid reserve tank 1 is further provided with heat(ing) coil 11, described heat(ing) coil 11 is connected with external steam pipeline, described heat(ing) coil 11 air inlets are provided with steam valve 12, described steam valve 12 can be also magnetic valve for common mechanical valve.
The wall of described alkali wash water liquid reserve tank is provided with airtight transparency window in the present embodiment, in described airtight transparency window, is provided with thermometer.During so concrete block clearing, the steam valve for alkali lye is heated is slowly opened into (1/4-1/3) aperture, steam flows into heat(ing) coil alkali lye is slowly heated, and the temperature that this chronothermometer shows should corresponding rising.The amplitude raising by alkali liquid temperature, the aperture of by-pass valve control, until temperature reaches (60 ± 2) ℃, after by steam valve slowly closing.(2-2.5) hour, the crystallization in caustic washing system is dissolved, and block clearing is complete.
