Description
Technical field
The utility model relates to a kind of cleaning device of graphite heat exchanger.
Background technology
Graphite heat exchanger belongs to volume type heat transmission equipment, is in graphite block, bore two groups of holes, and circulate material medium and service media (being generally water) respectively, and carry out heat exchange by graphite wall between two groups of media, pore size of media is smaller.
In compound potassium sulfate fertilizer production process, the heat exchanger major part that absorbing hydrogen chloride gas heat sink uses is tubular heat exchanger, inner array tubing matter is graphite, and after using the long period, exchanger tube wall foulant is more, and mostly be organic substance, cleaning difficulty is comparatively large, and traditional manner of cleaning up is for using Chemical cleaning mode and using iron wire manually to clear up row in-tube fouling, and cleaning difficulty is larger, and Chemical cleaning causes certain corrosion to equipment, cause shorten service life; Because graphite material is more crisp, often cause graphite tubulation to ftracture in scale removal process, cause production maintenance cost to increase.
Utility model content
The utility model, in order to solve the problem, proposes a kind of quick, convenient, efficient graphite heat exchanger cleaning device.This device without the need to using Chemical cleaning reagent, and need not manually be cleared up tubulation, decreases the possibility of graphite breakage.
To achieve these goals, the utility model adopts following technical scheme:
A kind of cleaning device of graphite heat exchanger, the both sides, bottom of graphite heat exchanger are respectively equipped with material inlet and recirculated water entrance, material inlet is provided with the first valve, recirculated water entrance is provided with the second valve, the both sides, top of graphite heat exchanger are respectively equipped with material outlet and circulating water outlet, material outlet is provided with the 3rd valve, and circulating water outlet is provided with the 4th valve.Material inlet and material outlet lay respectively at the both sides of graphite heat exchanger, and the pipeline of recirculated water entrance is provided with jet chimney, and jet chimney is provided with steam valve.The setting of jet chimney, avoids the trouble of more alias, and the opening and closing only by valve realizes the change of pipeline.
Described jet chimney is provided with Pressure gauge, for measuring the pressure of graphite heat exchanger inside.
Described jet chimney is provided with temperature-measuring gun, for measuring the temperature of graphite heat exchanger appearance.
The beneficial effects of the utility model are:
(1) the utility model adopts recirculated water to clean graphite heat exchanger, and cleaning effect is good, simple to operate;
(2) the utility model avoids Chemical cleaning to burnishers such as the corrosion of graphite heat exchanger and iron wires to the damage of graphite heat exchanger, avoids the damage of the graphite heat exchanger that labor cleaning causes simultaneously;
(3) the utility model reduces the labour intensity of workman, shortens scavenging period, improves operating efficiency, decreases maintenance cleaning charge use, adds the benefit of enterprise.
