Description
Technical field
The utility model relates to heat exchanger equipment and cleans field, refers to particularly a kind of on-line cleaning type heat exchanger
Background technology
In CSP conticaster production process, the soft water pipeline very high to water quality requirement need to prevent its internal incrustation.Soft water for production use can raise soft water temperature because of thermic load exchange after the equipment such as the converter oxygen gun of conticaster, sublance, the short net of LF stove, RH top rifle, conticaster crystallizer, soaking pit.These soft water that do not meet serviceability temperature requirement in order to allow temperature be elevated to can circulate and reuse, thereby will lower the temperature to the soft water after heating up.Due to the requirement of soft water closed circulating system to water quality, can not use the cooling system of general open type, as cooling tower etc., so selected the cooling system of plate type heat exchanger as soft water closed circulating system.
As shown in Figure 1, plate type heat exchanger comprises one group of wavy metal plate 6, longitudinal one end of wavy metal plate 6 is provided with fixed pressure plate 3, longitudinal other end of wavy metal plate 6 is provided with movable pressure plate 8, between fixed pressure plate 3 and movable pressure plate 8, be provided with the horizontal fixing guide rod of wavy metal plate 6, the outside of movable pressure plate 8 is provided with pillar 9, on four angles of wavy metal plate 6, all offers the hole, angle for medium runner, and hole, the angle inwall of plate 6 is provided with sealing ring 7 and is sealed.One Pai Jiao hole of plate groups upper end is passed by hot fluid (i.e. a water) water inlet pipe 1, another Pai Jiao hole is passed by cold fluid (being intermediate water) drainpipe 5, one Pai Jiao hole of plate groups lower end is passed by hot fluid drainpipe 4, another Pai Jiao hole is passed by cold fluid water inlet pipe 2, hot fluid water inlet pipe 1 is connected with hot fluid drainpipe 4, cold fluid water inlet pipe 2 is connected with cold fluid drainpipe 5, cold fluid and hot fluid alternately flows through respectively runner separately and passes through plate heat exchange and transferring heat under the guiding of sealing gasket, heat exchange finishes from hot fluid outlet pipe 4 and cold fluid outlet pipe 5, to flow out and enter water circulation system separately respectively afterwards.
A whole set of plate groups is installed between lower guide rod, by two block frames (fixed pressure plate and movable pressure plate), is clamped to fluid-encapsulated required size.What cold fluid was taken is the water of cold water well in clean circulating system, and hot fluid is for needing the soft water of cooling.Because cold fluid is the water of partly opening a way from cold water well, suspension content higher (this system suspension standard is≤20mg/L) in water, the calcium ions and magnesium ions of clean circulating water is higher, heat exchange will inevitably make calcium ions and magnesium ions crystal separate out later, do not stopping transport in the heat exchanging process turning for a long time, in water, suspension and calcium ions and magnesium ions crystal can condense and deposit to plate and the runner fouling that causes cold fluid to flow through on plate, because plate type heat exchanger flow area is less, after fouling, easily produce and stop up, cause heat exchange effect bad, the safety of equipment and user's just conventional thermal effect have been affected, be specially:
1, the long-term plate using changes and needs periodic cleaning, removes fouling and take and ensure that it reaches qualified heat exchange effect (the average cleaning frequency is 1 year 1 time);
2, plate changes while cleaning and requires to shut down dismounting, cannot normally work, and need to enable a standby plate and change;
3,1 platen changes cleaning needs 5 workmans dismantle 100 multi-disc plates with giant, to clean piecewise, after cleaning, also will install piecewise, is consuming timely generally a whole day.
Therefore, need improve prior art.
Summary of the invention
The purpose of this utility model is exactly the deficiency that will solve above-mentioned background technology, provide a kind of can guarantee heat exchanger when cleaning without shutdown, can reduce again the on-line cleaning type heat exchanger of needed complicated procedures of forming while cleaning.
The technical solution of the utility model is: a kind of on-line cleaning type heat exchanger, comprise the hot fluid water inlet pipe that is arranged on heat exchanger upper end, cold fluid drainpipe and be arranged on the hot fluid drainpipe of heat exchanger lower end, cold fluid water inlet pipe, described hot fluid water inlet pipe and hot fluid drainpipe are connected, described cold fluid water inlet pipe and cold fluid drainpipe are connected, it is characterized in that: described cold fluid water inlet pipe sidewall is provided with admission line, described admission line is provided with intake valve, described cold fluid drainpipe sidewall is provided with drainage pipeline, described drainage pipeline is provided with draining valve.
In such scheme:
One end of described admission line is connected with extraneous blowing plant, and the other end that described admission line penetrates in cold fluid water inlet pipe is provided with the wireway parallel with cold fluid water inlet pipe.
Described heat exchanger is board-like heat exchanger, described board-like heat exchanger comprises one group of plate, longitudinal one end of described plate is provided with fixed pressure plate, longitudinal other end of described plate is provided with movable pressure plate, between described fixed pressure plate and movable pressure plate, be provided with the horizontal fixing guide rod of plate, the outside of described movable pressure plate is provided with pillar, on four angles of described plate, all offers the hole, angle as medium runner, and hole, the angle inwall of described plate is provided with sealing ring; One Pai Jiao hole of described one group of plate upper end is passed by cold fluid drainpipe through, another Pai Jiao hole by hot fluid water inlet pipe, and a Pai Jiao hole of described one group of plate lower end is passed by cold fluid water inlet pipe through, another Pai Jiao hole by hot fluid drainpipe.
When heat exchanger will clean, heat exchanger is normally water inlet still, only need close the valve of cold fluid drainpipe, the draining valve that the intake valve that unlatching admission line is provided with and drainage pipeline are provided with, and mixing wastewater with air carries out on-line cleaning to pipeline; When the draining of drainage pipeline becomes clear water by muddy addle, close draining valve and intake valve, the valve of cold fluid drainpipe, clean complete, the heat exchanger use of can normally devoting oneself to work.
The utility model is simple in structure, reasonable in design, can guarantee plate type heat exchanger when cleaning without shutdown, can reduce again needed complicated procedures of forming while cleaning, both saved time, reduce again labour's consumption, can also guarantee cleaning performance.
