Abstract
The utility model relates to a heat exchanger descaling device for stainless steel heat exchanger and graphite condenser which comprises a centrifugal pump, wherein, the centrifugal pump is communicated with a circulation tank water outlet of a circulation tank through a water inlet of centrifugal pump, a water outlet of the centrifugal pump is communicated with a water inlet of heat exchanger, a water outlet of heat exchanger is communicated with the circulation tank, and the circulation tank is provided with a foam overflow vent. The utility model has the advantages of simple and easy scaling treatment, low treatment cost, time saving and high efficiency.
Description
Technical field
The utility model belongs to chemical industry heat exchanger descalling technique field, particularly a kind of heat exchanger apparatus for eliminating sludge that stainless heat exchanger and graphite condenser are carried out scale removal.
Background technology
The usually fouling and cause heat exchanger effectiveness to reduce greatly of Chemical Manufacture enterprise heat exchanger.Particularly some manufacturing enterprises of northern China utilize the advantage in winter, utilize that river or well water are unprocessed directly lowers the temperature, and cause equipment or pipeline scale serious.Use scale remover or utilize professional cleaning company to clean, expensive cleaning charge usefulness allows some medium-sized and small enterprises feel painstaking.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art and provides a kind of processing fouling simple and easy to do, and disposal cost is low, the heat exchanger apparatus for eliminating sludge of time-saving and efficiency.
The purpose of this utility model is achieved in that and comprises centrifugal pump, centrifugal pump is connected by the circulating tank delivery port of centrifugal pump water inlet and circulating tank, centrifugal pump delivery port and heat exchanger water inlet are connected, and heat exchanger delivery port and circulating tank are connected, and circulating tank is provided with the foam overfall.
It is simple and easy to do to the utlity model has the processing fouling, and disposal cost is low, the advantage of time-saving and efficiency.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, the utility model comprises centrifugal pump 1, and centrifugal pump 1 is connected by the circulating tank delivery port 5 of centrifugal pump water inlet 2 with circulating tank 6, and centrifugal pump delivery port 3 is connected with heat exchanger water inlet 4, heat exchanger delivery port 8 is connected with circulating tank 6, and circulating tank 6 is provided with foam overfall 7.
The utility model employed scale remover in circulating tank 6 is a concentration 16-18% diluted acid, can be dilute sulfuric acid, rare nitric acid, watery hydrochloric acid, the most handy rare nitric acid.Thickness according to the dirt layer, estimation needs scale removal weight, calculate the amount of used rare nitric acid, earlier nitric acid is made into normal concentration, squeeze into circulating tank (about 2 tons of stainless steel or enamel material), with corrosion resisting centrifugal pump this nitric acid is squeezed into the heat exchanger water inlet from the circulating tank bottom, flow back into circulating tank through the heat exchanger delivery port again, in cleaning process, have a large amount of foams to overflow from circulating tank, two kinds of situations are arranged when no a large amount of foams overflow after circulation a period of time, the one, the nitric acid that scale removal is used uses up, or the dirt layer is intact clearly, if the dirt layer is also unclear intact, replenish rare nitric acid again, circulation is after 120 minutes like this, and the emptying reaction waste is washed with clear water and to be got final product in 20 minutes.
