Description
Technical field
The utility model relates to a kind of automatic control chlorine residue devices, belong to water-treatment technology field.
Background technique
In the middle reverse osmosis field of water depth reuse, chlorination is the important link of Water-quality control.Generally in the original of reuse
Sodium hypochlorite is added in water water to sterilize.Raw water contacts after adding sodium hypochlorite by certain time, for inactivate microorganism in water,
Chlorine dose consumed by oxidation of organic compounds and reducing substances etc. is known as chlorine demand.But chlorine is in water as water temperature and time can wave
Hair, in order to inhibit the breeding of residual microbial in water, need to maintain a small amount of chlorine residue in former pond.What this just needed to be added to the water
Chlorine residue will keep in a certain range, needing dose to be used few but guaranteeing that contents of residual chlorine is stablized.Such as thrown according to artificial
Medicine, labor intensity of workers is big and safety is poor, and the bad assurance of the dose added, which can not control, continuously to be added；If using dosing meter
Amount pump adjusts dosage with flow of inlet water, is to become always since microorganism is not fixed and invariable in middle water water and middle water
Change, so dosage is difficult to accurately control, cause chlorine residue addition not to be is exactly less that additional amount is big more, wastes medical fluid, adds
Enter the effect that amount has been lacked and do not had sterilization.
Summary of the invention
In order to solve the problems in the existing technology, the utility model provides a kind of automatic control chlorine residue device.It should
Apparatus structure is simple, at low cost, not by the variation of the factors such as microorganism and temperature in inflow fluctuation and water inlet, can be always maintained at
The amount of chlorine residue is in reasonable range in former pond.
The technical solution adopted in the utility model is: a kind of automatic control chlorine residue device, it includes passing through resistance to sodium hypochlorite
The sequentially connected liquor natrii hypochloritis's tank in pvc pipe road, diaphragm metering pump and former pond, liquor natrii hypochloritis's tank are equipped with liquid level
Meter；Safety valve, check valve and flowmeter are successively arranged in the exit of diaphragm metering pump；The bottom of the former pond is equipped with chlorine residue
Detector；Residual chlorine detecting instrument, liquidometer and diaphragm metering pump are connected with control system, and control system uses PLC.
The beneficial effects of the utility model are: this automatic control chlorine residue device, it includes passing through the pvc pipe of resistance to sodium hypochlorite
The sequentially connected liquor natrii hypochloritis's tank in road, diaphragm metering pump and former pond, liquor natrii hypochloritis's tank are equipped with liquidometer；?
The exit of diaphragm metering pump is successively arranged safety valve, check valve and flowmeter；It is detected equipped with chlorine residue the bottom of the former pond
Instrument；Residual chlorine detecting instrument, liquidometer and diaphragm metering pump are connected with control system.The apparatus structure is simple, at low cost, is not intake
The variation of the factors such as microorganism and temperature, can be always maintained at the amount of chlorine residue in former pond in reasonable range in amount fluctuation and water inlet
It is interior.
Detailed description of the invention
Fig. 1 is a kind of system schematic for automatically controlling chlorine residue device.
In figure: 1, liquor natrii hypochloritis's tank, 2, liquidometer, 3, diaphragm metering pump, 4, check valve, 5, safety valve, 6, flow
Meter, 7, former pond, 8, residual chlorine detecting instrument, 9, the pvc pipe of resistance to sodium hypochlorite road, 10, control system.
Specific embodiment
Fig. 1 is a kind of system schematic for automatically controlling chlorine residue device.This automatic control chlorine residue device, it includes passing through
The sequentially connected liquor natrii hypochloritis's tank 1 in the pvc pipe of resistance to sodium hypochlorite road 9, diaphragm metering pump 3 and former pond 7, the sodium hypochlorite
NaOH solution tank NaOH 1 is equipped with liquidometer 2；Safety valve 5, check valve 4 and flowmeter 6 are successively arranged in the exit of diaphragm metering pump 3；It is described
The bottom of former pond 7 is equipped with residual chlorine detecting instrument 8；Residual chlorine detecting instrument 8, liquidometer 2 and diaphragm metering pump 3 and 10 phase of control system
Even.
Control system uses PLC, PLC, that is, programmable logic controller (PLC), and programmable logic controller (PLC) is kind exclusively in work
The digital operation electronic system applied and designed under industry environment.It uses a kind of programmable memory, deposits inside it
Storage executes the instruction of the operations such as logical operation, sequential control, timing, counting and arithmetical operation, by digital or analog
Input and output control various types of mechanical equipments or production process.Present simplest Siemens S7 system common on the market
Column PLC is small in size, speed is fast, standardization, has network communications capability, with better function, reliability is higher, S7-200 PLC
(6ES7211-0BA23-0XB0, AC/DC/ relay, 6 points of inputs, 4 points of outputs) are the PLC of subminaturization, it is suitable for each row
Each industry, automatic detection, monitoring and control in various occasions etc., the power of S7-200 PLC make its no matter single-unit operation,
Or it is linked to be network and can realizes complicated control function.
By adopting the above technical scheme, in 3 Outlet check valves 4 of diaphragm metering pump to prevent drug solns reflux, safety valve 5 to protect
Protect diaphragm metering pump 3 and pipeline；Flowmeter 6 is installed to measure on dosing pipe, residual chlorine detecting instrument 8 is installed in 7 bottom of former pond,
Being mounted on floor detection can guarantee that chlorine residue does not have dead angle in former pond；Residual chlorine detecting instrument 8, liquidometer 2 and diaphragm metering pump 3 and control
System 10 processed be connected, PLC(programmable logic controller (PLC) can be used in control system 10) receive residual chlorine detecting instrument 8, liquidometer 2 letter
Number and signal gives diaphragm metering pump 3 to instruct based on the received, residual chlorine detecting instrument 8 and diaphragm metering pump 3 link, when control system 10
It was found that the instruction of diaphragm metering pump 3 starting when the numerical value of residual chlorine detecting instrument 8 is lower than chlorine residue setting value, when control system 10 finds chlorine residue
The instruction of diaphragm metering pump 3 stops when the numerical value of detector 8 is higher than chlorine residue setting value；Regardless of microorganism in inflow fluctuation and water inlet
Increase and the variation of the factors such as temperature can keep the amount of chlorine residue in former pond in reasonable range.Liquidometer 2 and diaphragm meter
The 3 linkage protection of amount pump, when the numerical value of the discovery liquidometer 2 of control system 10 is lower than setting value, the instruction of diaphragm metering pump 3 stops, when
Control system 10 finds the instruction of diaphragm metering pump 3 starting when the numerical value of liquidometer 2 is higher than setting value.
