Description
Technical field
The utility model relates to a kind of cleaning and descaling device, especially the device that a kind of graphite heat exchanger shell side incrustation scale is removed online is related to, its can not open graphite heat exchanger and do not remove original connecting pipe prerequisite under, adopt the method for valve transfer, complete pickling descaling.
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, is generally 6 ~ 20mm.After using a period of time, in heat transferring medium hole, the dirty layer of normal formation, affects heat exchange.Because graphite heat exchanger internal structure is more complicated, when internal incrustation affects heat exchange, if cleaning, need first to disassemble graphite equipment, then adopt the incrustation scale in mechanical means removing graphite heat exchange unit block hole, such mode wastes time and energy, and is easy to damage graphite heat exchanger.
Given this, provide a kind of do not open graphite heat exchanger and do not remove original connecting pipe prerequisite under, graphite heat exchanger shell side is carried out to the device of on-line cleaning scale removal, become industry study direction.
Utility model content
In order to solve problems of the prior art, the purpose of this utility model is to provide a kind of graphite heat exchanger on-line cleaning apparatus for eliminating sludge, its can not open graphite heat exchanger and do not remove original connecting pipe prerequisite under, on-line cleaning scale removal is carried out to graphite heat exchanger shell side, it also avoid damage graphite heat exchanger simultaneously.
To achieve these goals, the technical solution of the utility model is:
A kind of graphite heat exchanger on-line cleaning apparatus for eliminating sludge, the side, bottom of graphite heat exchanger is connected with inlet line, described inlet line is provided with shell side service media inlet line control valve, side, top is connected with outlet line, described outlet line is provided with shell side service media outlet line control valve, this device comprises:
Be arranged at the first branch line in inlet line, this first branch line be provided with pickling descaling liquid import barrier valve;
Be arranged at the second branch line on outlet line, this second branch line be provided with pickling descaling liquid control of export valve.
As one of preferred embodiment, described inlet line and recirculated cooling water are supplied device and are communicated with.
Preferably, described first branch line is communicated with pickling descaling liquid circulating pump.
Preferred, described inlet line and outlet line are arranged at the same side of graphite heat exchanger.
Further, the opening direction of described first branch line down.
Compared with prior art, the beneficial effects of the utility model are:
The utility model structure is simple, reasonable in design, can not open graphite heat exchanger and do not remove original connecting pipe prerequisite under, adopt the method for valve transfer, complete and online pickling descaling is carried out to graphite heat exchanger shell side, it also avoid damage graphite heat exchanger simultaneously; And cleaning and descaling process can repeatedly use as required, as long as each operation control valve door, do not need to disassemble graphite heat exchanger, saved scavenging period and cost, improve operating efficiency, application prospect is good.
Accompanying drawing explanation
For structure of the present utility model is described, below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in more detail.

Description of reference numerals: 1-graphite heat exchanger, 2-inlet line, 20-shell side service media inlet line control valve, 3-outlet line, 30-shell side service media outlet line control valve, 4-first branch line, 40-pickling descaling liquid import barrier valve, 5-second branch line, 50-pickling descaling liquid control of export valve, A-recirculated cooling water, B-pickling descaling liquid.
Detailed description of the invention
Below in conjunction with embodiment, the utility model is described in further detail.
Shown in Figure 1, the graphite heat exchanger on-line cleaning apparatus for eliminating sludge of the present embodiment, the side, bottom of graphite heat exchanger 1 is connected with inlet line 2, described inlet line 2 is provided with shell side service media inlet line control valve 20, side, top is connected with outlet line 3, described outlet line 3 is provided with shell side service media outlet line control valve 30.Pickling descaling liquid import barrier valve 40 is provided with the inlet line 2 be connected between graphite heat exchanger shell side being arranged on the first branch line 4, first branch line 4 at the shell side service media inlet line control valve 20 of graphite heat exchanger 1; Similarly, pickling descaling liquid control of export valve 50 is provided with at the shell side service media outlet line control valve 30 of graphite heat exchanger 1 with the outlet line 3 be connected between graphite heat exchanger shell side being arranged on the second branch line 5, second branch line 5.
During normal use, close pickling descaling liquid on the first branch line 4, second branch line 5 into and out of by-pass valve control 40 and 50, recirculated cooling water A controls by normal.Graphite heat exchanger 1 internal incrustation affects heat exchange when needing cleaning and descaling, close shell side service media into and out of pipeline control valve 20 and 30, first branch line 4 connects pickling descaling liquid circulating pump (not identifying in figure), open the pickling descaling liquid import barrier valve 40 on the first branch line 4 and the pickling descaling liquid control of export valve 50 on the second branch line 5, remove the fouling in graphite heat exchanger with the pickling descaling liquid B that with the addition of corrosion inhibiter; After cleaning terminates, close pickling descaling liquid import barrier valve 40 and pickling descaling liquid control of export valve 50, open shell side service media into and out of pipeline control valve 20 and 30, use graphite heat exchanger by normal procedure.
Cleaning and descaling process can repeatedly use as required, as long as each operation control valve door, does not need to disassemble graphite heat exchanger.
In sum, the utility model can not open graphite heat exchanger and do not remove original connecting pipe prerequisite under, adopt the method for valve transfer, complete and online pickling descaling is carried out to graphite heat exchanger shell side, it also avoid damage graphite heat exchanger simultaneously, saved scavenging period and cost, improve operating efficiency, application prospect is good.
