Background technology
Because through-flow boiler is using bellows and the furnace binding of uniqueness, heat-transfer effect, economizer greatly improved（Condenser）Waste heat is absorbed, feed temperature is improved and is realized energy-efficient purpose, boiler thermal output is greatly improved, and furnace binding miniaturization, reservoir storage are few, boiler is only needed 5 minutes from supply is started to using the steam of pressure, a large amount of saving preheating times and expense.So, up to more than 85%, because of environment and the needs of energy-conservation, the demand of tubular boiler increases substantially through-flow boiler occupation rate of market for the country.Through-flow boiler also has larger difference with the entirely different using method of hot water boiler structure.When producing steam because of through-flow boiler, water is concentrated hundred times in pot, therefore very high to water quality requirement（It is required that the water hardness is less than 0.03mmol/L）, while automatic concentration blowdown apparatus detection pot electrical conductivity of water, automatic pollution discharge when exceeded.In order to typically utilize " water softener " to be softened to boiler supplying soft water, but after " water softener " work long hours, the reason such as ion exchange resin hydraulic performance decline or power failure can use water hardness increase, therefore detect the water hardness at any time.Hardness of water is typically with the measurement of conductivity meter, total dissolved solid instrument or chemical reagent, but conductivity meter, total dissolved solid instrument are only applicable to water softening before processing.Because in water softening process, carbonate is replaced by sodium ion, therefore, although hard water is into soft water, but total dissolved solid value does not change.At present most domestic uses merely qualitatively water quality and hardness measuring agent method.About 50ml water samples are taken in transparent vessel, two titration property test agents are added dropwise in water sample, the aobvious blue water quality that is of solution is qualified, and it is unqualified that the aobvious redness of solution is water quality.The method is simple to operate, to sampling amount without strict demand, but must manually operate, and manual detection is it is difficult to ensure that the accuracy and test quality of test interval.
The content of the invention
The utility model is in order to overcome the shortcomings of prior art water hardness manual detection, and a kind of automatic steam boiler online agent detection devices of the water hardness are provided, the device carries out full-automatic online water hardness detection using simple qualitatively water quality and hardness measuring agent method, realize the exceeded warning of automatic sampling, automatic detection, the water hardness, report to the police without reagent, Water free alarming, and record time of fire alarming, address.With upper microcomputer remotely control, query function, and with reliability height, short detection time, small volume, low cost, the features such as easy to maintenance.
For achieving the above object, the technical scheme that the utility model is adopted is：A kind of automatic steam boiler online agent detection devices of the water hardness, which includes the reagent mixing pond that upper and lower side is respectively provided with delivery port and water inlet, White LED light source and color sensor that stirring pool or so outside is respectively equipped with, the magnetic stirrer that stirring pool bottom is provided with, the injection needle being arranged in the stirrer cover of stirring pool top, teflon hose, reagent detects infrared transceiver sensor, miniature peristaltic pump, reagent bottle and controller, the syringe needle of described injection needle one end is placed in stirring pool, the other end connection teflon hose of injection needle, teflon hose is sequentially connected reagent detection infrared transceiver sensor, minitype creepage pump discharge, the teflon hose connection reagent bottle of connection minitype creepage pump intake, described controller connects respectively color sensor, miniature peristaltic pump.
Further, the water inlet connection flexible pipe of described stirring pool lower end, flexible pipe is connected on water softener outlet conduit by the magnetic valve which is provided with；The delivery port connection delivery hose of described stirring pool upper end.
Further, it is provided with magnetic stirrer in described stirring pool.
Further, described controller is made up of one-chip computer, liquid crystal touch screen, miniature peristaltic pump drive circuit, signal deteching circuit, warning circuit, communication interface, Switching Power Supply connection.
The automatic steam boiler online agent detection devices operation principle of the water hardness：When being detected, magnetic valve is opened, water sample is poured in stirring pool, magnetic valve is closed after certain hour.The corresponding output quantity of color sensor measurement water sample white level, and by infrared transceiver sensor detection reagent, without reagent signal, then report to the police, otherwise start miniature peristaltic pump and push trace reagent, and starting magnetic stirrer generation alternating magnetic field, alternating magnetic field drives stirrer stirring water sample in pond reagent is uniformly spread.Color sensor output is detected after spending more than ten seconds, if output quantity is unchanged, water shortage is illustrated, Water free alarming is carried out, otherwise measured value is compared in the color settings threshold values of storage and judges light red and light blue.When water sample hardness is less than 0.03 mmol/L, that is, the water hardness is qualified when showing blue, and when water sample hardness is more than 0.03 mmol/L, that is, the water hardness is unqualified when showing red, is reported to the police, and stores time of fire alarming.The water sample that magnetic valve is bled off in stirring pool is opened in measurement after terminating, clean stirring pool.
The utility model device carries out full-automatic online water hardness detection using simple qualitatively water quality and hardness measuring agent method, realizes the exceeded warning of automatic sampling, automatic detection, the water hardness, reports to the police without reagent, Water free alarming, and records time of fire alarming, address.Type of alarm has bus warning, network alarming, sound and light alarm.With upper microcomputer remotely control, query function, and with reliability height, short detection time, small volume, low cost, the features such as easy to maintenance.The beneficial effects of the utility model are that instead of the artificial Always Online" detection automatic steam boiler water hardness, save manpower, improve efficiency, improve accuracy of detection, reduce testing cost.
