Abstract
The utility model discloses a device for washing a tubular heat exchanger of a digestion workshop, which comprises a compressed air tube (1) of the digestion workshop, and a dilute acid tank (2) of the digestion pickling workshop, a washing tank (3) is also arranged in the digestion pickling workshop, and the compressed air tube (1), the dilute acid tank (2) and the washing tank (3) are provided with pipelines (5) circularly connected with the tubular heat exchanger (4). The utility model is provided with the washing tank in the digestion pickling workshop, and the compressed air tube, the dilute acid tank and the washing tank are provided with circular pipelines connected with the tubular heat exchanger, so the washing water can be recycled many times when the washing tank is used for storing the washing water, and the amount of the washing water for temperature reduction is saved. The washing tank is connected with a sewage discharge pipe which is connected with a sewage treating workshop, so the problem of environmental pollution is solved.
Description
Technical field
The utility model relates to a kind of device that cleans stripping workshop tubular heat exchanger, belongs to technical field of aluminum electrolysis.
Background technology
In the production process of aluminium oxide, the tubular heat exchanger in stripping workshop needs it is cleaned during parking maintenance.Existing cleaning step is: 1: the compressed air binder with the stripping workshop draws off the slip in the tubular heat exchanger equipment; 2: with recirculated water tubular heat exchanger is carried out circulation flushing to reach the cooling purpose, wash Hou Shui and return stripping pickling workshop, leave in the cesspit of bottom, workshop, regularly efflux; 3: with the dilute sulfuric acid that leaves stripping pickling workshop dilute acid bath in tubular heat exchanger is cleaned, wash the back dilute sulfuric acid and return dilute acid bath; 4: the compressed air with the stripping workshop is sent dilute sulfuric acid residual in the tubular heat exchanger back to dilute acid bath.There is following defective in the existing device that cleans stripping workshop tubular heat exchanger: the first, owing to there is not special equipment to store washing Hou Shui, recirculated water can only once be lowered the temperature to tubular heat exchanger, promptly can't be recycling; The second, wash Hou Shui and contain a certain amount of alkali, directly deposit in the cesspit and can produce corrosiveness ground and some structures in stripping pickling workshop; The 3rd, regularly directly efflux, containing buck after washing can pollute environment.
Summary of the invention
The technical problems to be solved in the utility model is, a kind of water saving, environmental protection is provided, can not influence the device of the cleaning stripping workshop tubular heat exchanger of workshop ground and structures, can overcome the deficiencies in the prior art.
The technical solution of the utility model; It comprises the compressed air hose in stripping workshop and the dilute acid bath in stripping pickling workshop, also is provided with the wash water groove in stripping pickling workshop, and is provided with the pipeline that links to each other with the tubular heat exchanger circulation at compressed air hose, dilute acid bath and wash water groove.
Be connected with bilge discharge pipe on the wash water groove, bilge discharge pipe is connected with the sewage disposal workshop.
Be provided with a through tube at tubular heat exchanger on dilute acid bath and wash water groove, the drain pipe of wash water groove and dilute acid bath is connected with through tube.
Compared with the prior art, the utility model is by establishing the wash water groove in addition in stripping pickling workshop, and is provided with the circulating line that links to each other with tubular heat exchanger at compressed air hose, dilute acid bath and wash water groove.Adopt the wash water groove to store like this and wash Hou Shui, wash water is recycled repeatedly, saved the cooling leaching requirement.Be connected with bilge discharge pipe on the wash water groove, bilge discharge pipe is connected with the sewage disposal workshop, so just can solve environmental pollution problems.Be provided with a through tube at tubular heat exchanger on dilute acid bath and wash water groove, the drain pipe of wash water groove and dilute acid bath is connected with through tube, so just can save duct length, reduces engineering cost.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Embodiment 1: as shown in Figure 1, in stripping pickling workshop, build earlier a wash water groove 3, with pipeline 5 wash water groove 3 is connected with tubular heat exchanger 4 then, constitute the circulatory system, when the member circulatory system, for reducing the pipeline consumption, reduce construction costs, the pipeline of wash water groove 3 can be connected on the pipeline of dilute acid bath 2; And connect a bilge discharge pipe 6 on wash water groove 3, bilge discharge pipe 6 is connected with the sewage disposal workshop.After building up the heat-exchange system of wash water groove 3 and tubular heat exchanger 4, its cleaning step is: a: the compressed air binder with in the stripping workshop compressed air hose 1 draws off the slip in the tubular heat exchanger equipment 4; B: the water in the wash water groove 3 is delivered to tubular heat exchanger 4 by the pipeline of dilute acid bath 2, after finishing, cleaning returns wash water groove 3, recycle, the temperature of unit to be cleaned drops to below 60 ℃, wash water stops to carry, c also delivers to tubular heat exchanger 4 with the dilute sulfuric acid in the dilute acid bath 2 by pipeline, cleans and returns dilute acid bath 2 after finishing, and d, sends the remaining dilute sulfuric acid in the tubular heat exchanger 4 back to dilute acid bath 2 with compressed air.
