The graphite heat exchanger damage monitoring system is characterized in that a conductometer 5 is arranged at a condensate water return pipe 4 of a graphite heat exchanger 1 and is used for directly measuring the conductivity of condensate water and judging whether the graphite heat exchanger is damaged and generates acid leakage according to the change of the conductivity; an alarm device is connected to the conductometer; the electric conductance value measured by the conductometer is input into a programmable logic controller of an operating platform 6 through analog for realize real-time monitoring; and the electric conductance value is read from a dial plate of the conductometer and also can be read on the operating platform. The graphite heat exchanger damage monitoring system disclosed by the utility model can be used for monitoring the operation condition of the graphite heat exchanger in real time, replacing the damaged heat exchanger in time, ensuring heating and concentration of acid liquor and effectively recycling condensate, thereby saving water source and ensuring the pickling quality.
Description
Technical field
The utility model relates to the graphite heat exchanger damage monitoring system device on a kind of metal plate and belt pickling line.
Background technology
At present, in the metal plate and belt cold-rolled process and on metal plate and belt plating and the galvanization production line, all need metal plate and belt is carried out pickling.The pickling line in past all adopts steam directly to feed the heating means of acid solution, but this method can produce a large amount of acid mists, has strengthened the load of air draft exhaust steam system; Cover under the poorly sealed situation at groove, acid mist escapes environment and place is caused serious corrosive nature, and uses the steam heating water of condensation; Constantly diluting soln reduces acid concentration fast, thereby makes the pickling effect variation; Occur metal plate and belt cleaning dirty, owe defective such as pickling, and the spent acid amount increases, and will cause the recovery system imbalance; The part of draining spent acid increases the acid consumption, causes production cost higher.For overcoming above drawback, acid solution is added thermal recovery graphite heat exchanger indirect heating replace steam direct heating of the prior art, can avoid steam directly to contact with acid solution, reduce the volatilization of acid mist, prevent the acid solution waste, environmental pollution.
Steam-heated form is adopted in the graphite heat exchanger heat exchange of adopting at present, and steam forms water of condensation through behind the graphite heat exchanger, and for the conserve water resource, the water of condensation of general interchanger is recyclable as the rinse water that clean section.But owing to adopt the mode of inside and outside convection current between the graphite block, under the effect of high temperature and acid solution impact load, the time one is long; The mechanical seal of sealing, sour pump, ball valve etc. are prone to corrosion damage between graphite block; Leak easily, cause the return water pipe of acid solution inflow heat exchanger, badly damaged interchanger; Influence the metal plate and belt pickling quality, and pollute the water of condensation water tank.If adopted the water after the pollution to carry out rinsing acid solution will be remained on the metal plate and belt, and cause metal plate and belt cleaning dirty, influence the surface quality of metal plate and belt.
Summary of the invention
The utility model is to the deficiency of above technical scheme, proposed a kind of pickling line graphite heat exchanger damage monitoring system, and whether in time monitor graphite heat exchanger has and damage and sour seepage takes place.
The technical scheme that the utility model adopted is:
A kind of pickling line graphite heat exchanger damage monitoring system comprises graphite heat exchanger 1, condensation water pot 2, vapour pipe 3, condensate ruturn pipe 4; Vapour pipe 3 links to each other with condensate ruturn pipe 4 through graphite heat exchanger 1; Condensate pipe 3 links to each other with condensation water pot 2; Condensate ruturn pipe (4) in said graphite heat exchanger (1) locates to install conductivity meter 5, and the data signal of conductivity meter 5 can be transferred to operator's console.
The beneficial effect of the utility model is: adopt the utility model to monitor the running condition of graphite heat exchanger in real time, when interchanger was damaged, the liquid conduction rate in the interchanger increased; Send the signal emergency alarm; In time change the graphite heat exchanger that damages, reclaim water of condensation and effectively utilize the conserve water resource; Guarantee the quality of pickling, prevent contaminate environment.

Among Fig. 1: graphite heat exchanger 1, condensation water pot 2, vapour pipe 3, condensate ruturn pipe 4, conductivity meter 5, operator's console 6
Embodiment
In order to be illustrated more clearly in the technical scheme in the utility model, in detail, intactly narrate the utility model pickling line graphite heat exchanger damage monitoring way below in conjunction with accompanying drawing.
As shown in the figure, acid solution is extracted out from acid tank through sour pump and is sent into graphite heat exchanger 1, and the top from graphite heat exchanger after graphite heat exchanger 1 heating flows back to acid tank, is the acid solution flow direction like the pipeline flow direction that does not mark among the figure.Graphite heat exchanger 1 send acid solution to send into steam through vapour pipe 3 after 2 minutes, and the steam of sending into forms water of condensation through graphite heat exchanger 1 back, and water of condensation is sent into condensation water pot 2 through TFL 4.4 places are equipped with conductivity meter 5 at return water pipe; Can directly measure the condensation electrical conductivity of water, judge that according to the variation of specific conductivity whether graphite heat exchanger 1 has damage and sour seepage takes place, and is connected with warning device with conductivity meter 5; Conductivity meter 5 records electric conductivity value is input to operator's console 6 through analog quantity programmable logic controller; Electric conductivity value can be read in the dial plate by conductivity meter 5, also can in operator's console 6, read, and accomplishes the real-time monitoring to graphite heat exchanger 1 running condition thus.
When graphite heat exchanger 1 works better, the water of condensation specific conductivity that records is about definite value A, proves not have sour seepage, and the water of condensation reuse can be used as the rinse water of rinsing section; When the water of condensation conductivity value that records increases suddenly,, output signal to warning howler greater than definite value A; Warning howler is made the guard signal that graphite heat exchanger 1 damages; Think that then graphite heat exchanger has damaged and sour seepage takes place, because the damage of graphite heat exchanger is little to the pickling quality influence in the short period of time, so when equipment is out of service, can overhauls or change to graphite heat exchanger; Water of condensation in the condensation water pot is handled accordingly and is drained after up to standard, no longer is used for doing cleaning section rinse water.After treating that maintenance is good or changing graphite heat exchanger, carry out pickling again, treat that the water of condensation specific conductivity in the condensation water pot returns to electrical conductivity of water value definite value A; Can be as the rinse water that clean section; The graphite heat exchanger works better continues the acid solution that gets into acid tank is heated system's works better.
The above; Be merely the embodiment of the utility model; But the protection domain of the utility model is not limited thereto; Any technician who is familiar with the present technique field can expect changing or replacement in the technical scope that the utility model discloses easily, all should be encompassed within the protection domain of the utility model.Therefore, the protection domain of the utility model should be as the criterion with the protection domain of said claim.
