Abstract
A kind of on-line cleaning system for sulfuric acid production line, the entrance of one group of heat interchanger (3) is communicated by pipeline with the outlet of mixing valve (8), and the outlet of one group of heat interchanger (3) is communicated by pipeline with the water inlet of circulating water pool (1), PH sensor (9) is arranged in the PH sensor installation port of circulating water pool (1), and PH sensor (9) is connected by communication by Analog input mModule (10) and PLC(11), PLC(11) respectively by the start and stop of relay and A.C. contactor control A pump (4) and B pump (5) and working time.The utility model advantage is: without the need to dropping into large number quipments transformation, can start on-line cleaning, the concentrated sulphuric acid produced for our factory of medicament that cleaning uses, each cleaning need about 1-2 ton, cheap without the need to outsourcing, and on-line cleaning effect is better.
Description
Technical field
The utility model relates to sulfuric acid production line cleaning field, is specifically related to a kind of on-line cleaning system for sulfuric acid production line.
Background technology
At present, because sulfuric acid production plant continuity is strong, off-line cleaning can not be carried out to fouling equipment, and sulphuric acid process has a large amount of heat transmission equipment, wherein heat eliminating medium is in the majority with water, because industrial circulating cooling water rate of water make-up will strictly control and water quality of fetching water is poor, long-time running easily causes each heat transmission equipment fouling, heat transfer effect declines, and each technic index can not control to run in normal range, threatens normal production time serious.
Utility model content
At present of the present utility model, because sulfuric acid production plant continuity is strong, off-line cleaning can not be carried out to fouling equipment, and sulphuric acid process has a large amount of heat transmission equipment, wherein heat eliminating medium is in the majority with water, because industrial circulating cooling water rate of water make-up will strictly control and water quality of fetching water is poor, long-time running easily causes each heat transmission equipment fouling, heat transfer effect declines, each technic index can not control to run in normal range, threaten the deficiency of normal production time serious, and a kind of on-line cleaning system for sulfuric acid production line is provided.
The utility model comprises circulating water pool, sulfuric acid pond, one group of heat interchanger, A pump, B pump, A solenoid valve, B solenoid valve, mixing valve, PH sensor, Analog input mModule and PLC, circulating water pool is respectively equipped with water inlet, water delivering orifice and PH sensor installation port, mixing valve be connected with A solenoid valve and A pump between one of them entrance and water delivering orifice of circulating water pool in turn, B solenoid valve and B pump is connected with in turn between another entrance of mixing valve and the outlet in sulfuric acid pond, the entrance of one group of heat interchanger is communicated by pipeline with the outlet of mixing valve, and the outlet of one group of heat interchanger is communicated by pipeline with the water inlet of circulating water pool, PH sensor is arranged in the PH sensor installation port of circulating water pool, and PH sensor is connected by communication by Analog input mModule and PLC, PLC is respectively by the start and stop of relay and A.C. contactor control A pump and B pump and working time.
The utility model advantage is: without the need to dropping into large number quipments transformation, can start on-line cleaning, the concentrated sulphuric acid produced for our factory of medicament that cleaning uses, each cleaning need about 1-2 ton, cheap without the need to outsourcing, and on-line cleaning effect is better.
accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Embodiment
As shown in Figure 1, the utility model comprises circulating water pool 1, sulfuric acid pond 2, one group of heat interchanger 3, A pump 4, B pump 5, A solenoid valve 6, B solenoid valve 7, mixing valve 8, PH sensor 9, Analog input mModule 10 and PLC11, circulating water pool 1 is respectively equipped with water inlet, water delivering orifice and PH sensor installation port, A solenoid valve 6 and A pump 4 is connected with in turn between one of them entrance of mixing valve 8 and the water delivering orifice of circulating water pool 1, B solenoid valve 7 and B pump 5 is connected with in turn between another entrance of mixing valve 8 and the outlet in sulfuric acid pond 2, the entrance of one group of heat interchanger 3 is communicated by pipeline with the outlet of mixing valve 8, and the outlet of one group of heat interchanger 3 is communicated by pipeline with the water inlet of circulating water pool 1, PH sensor 9 is arranged in the PH sensor installation port of circulating water pool 1, and PH sensor 9 is connected by communication with PLC11 by Analog input mModule 10, PLC11 is respectively by the start and stop of relay and A.C. contactor control A pump 4 and B pump 5 and working time.
Working method: when needing to clean the heat interchanger of sulfuric acid production line, PLC11 PLC11 starts work respectively by relay and A.C. contactor control A pump 4 and B pump 5, the water and sulfuric acid that are arranged in circulating water pool 1 and sulfuric acid pond 2 are pumped into mixing valve 8 and mix by A pump 4 and B pump 5 respectively respectively, the acid solution of diluting afterwards enters in one group of heat interchanger 3, final circulation enters in circulating water pool 1, PH sensor constantly detects the pH value in circulating water pool, when pH value is less than 4, PLC11 is quit work by relay and A.C. contactor control B pump 5, after A pump 4 works 20 minutes, PLC11 PLC11 quits work respectively by relay and A.C. contactor control A pump 4 and B pump 5, namely cleaning is completed.
