Description
Technical field
The utility model relates to the central control device of acid mist exhaust-gas treatment in manufacture of solar cells process.
Background technology
Can hydrochloric acid be produced, hydrofluoric acid in solar battery sheet production process, and the toxic and harmful such as nitric acid waste gas.Acid mist tower has can remove pernicious gas in air, the features such as applied widely, purification efficiency is high, and equipment resistance is low, and floor space is little.Acid waste gas is collected by airduct, enters acid mist tower by the twitch of blower fan, and with the process of alkali lye spray in acid mist tower, the alkali lye in acid mist tower alkali bucket puts into acid mist tower water tank by dosing pump.
Current multiple stage acid mist emission-control equipment adopts and manually adds the alkali bucket of multiple stage acid mist tower, due to alkali liquor absorption acid waste gas, in acid mist tower after a while, shower water electrical conductivity can raise, and easily causes inner-tower filling material crystallization, need human at periodic intervals's discharge opeing, and fluid infusion; Also need human at periodic intervals to check the pH value that acid mist tower sprays, alkali bucket liquid level etc., be not only not easy to operation, and the contact of personnel to chemicals can be increased, be unfavorable for healthy.
Utility model content
Utility model object: the utility model solves the problems referred to above, provides one and can realize automation and accurately control, and reduces personnel to the contact of chemicals, reduces the central control device of the acid mist exhaust-gas treatment of risk during operation.
Technical scheme: a kind of central control device of acid mist exhaust-gas treatment, comprises PLC control device and acid mist emission-control equipment, the touch-screen that described PLC control device comprises PLC and is connected with PLC; Described acid mist emission-control equipment comprises the alkali storage tank be connected with PLC respectively, two make-up valve, liquid level gauge, dosing pump and tapping valves; Also comprise and the membrane pump be connected by flexible pipe in the middle of described alkali storage tank and one of them make-up valve; And the acid mist tower to be connected with described dosing pump, tapping valve and another make-up valve; Described acid mist tower side is connected with water pump, and water pump is connected with acid mist tower internal sparger pipe by pipeline; Described liquid level gauge is connected with alkali bucket.
Particularly, pH meter is installed in described shower and controls dosing pump dosing.
Particularly, fluid infusion time showing module, drain time display module, alkali bucket liquid level display module, pH value display module and setting input module is integrated with in described touch-screen.
Beneficial effect: compared with prior art, the utility model advantage is:
1, realized the Centralized Monitoring of acid mist emission-control equipment by PLC central control device, comprise and control alkali bucket liquid level, the state of dosing pump pH value and fluid infusion and discharge opeing, does not need personnel to go to patrol and examine to scene.
2, realize remote control by PLC central control device, do not need personnel to operate to scene, just can revise discharge opeing at any time, the fluid infusion time, avoid the crystallization of inner-tower filling material.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with detailed description of the invention, illustrate the utility model further.
As shown in Figure 1, a kind of central control device of acid mist exhaust-gas treatment, comprises PLC control device and acid mist emission-control equipment, the touch-screen 1 that PLC control device comprises PLC 2 and is connected with PLC; Acid mist emission-control equipment comprises alkali storage tank 3, two make-up valve 8, liquid level gauge 6, dosing pump 7 and tapping valves 12 of being connected with PLC 2 respectively; Also comprise and be connected membrane pump 4 with in the middle of alkali storage tank 3 and one of them make-up valve 8 by flexible pipe; Dosing pump 7, tapping valve 12 are connected acid mist tower 11 with another make-up valve 8; Acid mist tower 11 side is connected with water pump 10, and water pump 10 is connected with acid mist tower 11 internal sparger pipe 9 by pipeline; Liquid level gauge 6 is connected with alkali bucket 5; PH meter is installed in shower 9 and controls dosing pump 7 dosing.
Fluid infusion time showing module, drain time display module, alkali bucket liquid level display module, pH value display module and setting input module is integrated with in touch-screen 1.Touch-screen 1 can set the time of acid mist tower 11 discharge opeing and fluid infusion, and all pumps and pneumatic operated valve etc. can be operated, the pH value in acid mist tower 11 water tank can be monitored simultaneously.
Acid mist tower 11 processes the acid waste gas from workshop, processing intent is reached by alkali liquor absorption, in the process absorbed, acid mist tower 11 shower water progressively becomes acid, and electrical conductivity, salt content raises, need to ensure that spray liquid is in alkalescence by adding alkali, and discharge the electrical conductivity that a part of water reduces spray liquid, salt content.
The liquid level gauge 6 of alkali bucket 5 controls membrane pump 4 when being in low liquid level and make-up valve 8 is opened, and carries out benefit alkali, stops during high liquid level; The pH meter be arranged in shower 9 controls dosing pump 7 and carries out dosing, and pH value, lower than 7, adds alkali, stops higher than 10; Tapping valve 12, make-up valve 8 control the fluid infusion discharge opeing of acid mist tower 11 respectively, and above operation all carrys out Centralized Monitoring by PLC control device, and can retouching operation on touch-screen 1.
