The utility model relates to an anti-corrosive chemical feeder for a hot-water boiler, belonging to the field of the boiler chemical feeder of the water treatment device. The anti-corrosive chemical feeder comprises a fabric filter, a jet pump, a pipeline for a physic liquor counter and a valve which are communicated, and the jet pump can be started by using the water-inflow pressure difference of a boiler feed pump. The anti-corrosive agent with high efficiency is added into the boiler water, the chemical-feeding quantity can be adjusted and can be visual and readable, and the utility model has the advantages of easy production, low cost, convenient arrangement, low running cost and reliable operation. The utility model is anti-corrosive in the boiler running, and the corrosion of the boiler and the hot-water system can be prevented effectively by discharging the water and not discharging the water during the boiler is stopped. The anti-corrosive chemical feeder can be used widely for the anti-corrosion of various hot-water boilers.
Description
The anticorrosion doser of a kind of hot-water boiler, it belongs to the boiler anti-corrosion doser class of water treatment facilities.
The main cause of heat power equipment metal erosion at present is the dissolved oxygen in the water, and how removing oxygen in water is the research topic that prevents the Boiler Metallic corrosion.A kind of method commonly used is a chemical deoxidization, uses more satisfactory oxygen-eliminating device to add oxygen scavenger sodium sulfite soup in boiler, obtains certain antiseptic effect.Yet the water temperature in the hot-water boiler does not reach saturation temperature, and evaporation loss and system loss generally are no more than 5%, but has many hot water boiler system water consumption bigger.The water consumption vary within wide limits, when using chemical deoxidization, oxygen scavenger addition root is not gone up at any time and is changed, and is difficult for levelling, influences antiseptic effect.
The chemical deoxidization equipment that prior art provides is by dirt separator, deaeration pump and controller, the oxygen-eliminating device that tubing pump and pipeline are formed.In boiler, add oxygen scavenger based on sodium sulfite.Its weak point is that oxygen scavenger regularly, quantitatively adds the deoxygenation medicinal cupping and mixes inhomogeneous; And the solvent demineralized water adds continuously, and liquor strength is constantly diluted, and when the pending water yield of the boiler that enters changed greatly, the addition of oxygen scavenger did not catch up with the needs of variation, is difficult to regulate control; Soup is imported boiler water with tubing pump, needs additionaling power, complex structure, bad maintenance, operating cost height.
The object of the present invention is to provide and a kind ofly utilize that boiler feedwater is pumped, intake pressure is poor, drive jet pump, carry efficient antiseptic and add boiler water, prevent the anticorrosion doser of hot-water boiler of boiler and hot-water heating system corrosion.
Technical solution of the present invention in conjunction with the accompanying drawings 1, the anticorrosion doser schematic diagram of hot-water boiler, Fig. 2, jet pump structure schematic diagram are described further:
The anticorrosion doser of hot-water boiler, by the outlet pipe 5 of water pipe 7 connection boiler feed pumps 4, through valve 8,9 logical fine filter 10 top water inlets, water pipe 3 is taken over the filter lower outlet, is connect the jet pump delivery port and connect boiler feed pump water inlet pipes 1, constitute boiler water by-pass flow pipeline through valve 17 through valve 2 connection jet pumps 16 water inlets, liquid medicine pipe 18.Soup meter 12 indicates scale for transparent tubular type side, and there is drain pipe the lower end, places in the protective cover 11, the cover top is provided with the lid that can open, close, and the lower end drain pipe is connected pencil 13 is connected jet pumps 16 through cock valve 14, needle valve 15 negative pressure mouth.Jet pump has mounting flange by the garden cylindricality pump housing 19, two, inner chamber connects back taper 22, garden cylindricality trunnion 21, less tapering delivery port 20 for offering negative pressure mouth 27 on the bigger garden cylindricality water inlet 23 bottom body walls from the top down, nozzle 26 tops are mounting flange, connect the garden post that cooperates with garden cylindrical hole 23 down, again is taper, inner chamber is that cylindricality water inlet 25 belows, garden are taper nozzle hole 24, the soup meter selects for use transparent glass or plastics, jet pump to select stainless steel or plastics manufacturing for use, and each parts is contained in the framework to be formed.The 6th, boiler.Efficient antiseptic is nontoxic medicine; at unlikely decomposition failure below 120 ℃; in a single day boiler blow-down water adds efficient antiseptic and takes effect immediately; beginning forms unsettled unimolecule diaphragm at the boiler iron surface; promptly play antisepsis; continue to add affiliation and form more stable diaphragm with metallic iron, after stable diaphragm formed, efficient antiseptic just can intermittently add.
The industry operation of the anticorrosion doser of hot-water boiler:
Open soup meter protective cover loam cake; in meter, fill with the efficient corrosion resisting agent solution; start boiler feed pump and boiler water is added boiler through water pipe 5; open all valves on the by-pass flow pipeline; water under high pressure enters fabric filter through water pipe 7; the filtering mechanical admixture; enter jet pump again through liquid medicine pipe 18 backflow water pipes 1 through water pipe 3; open cock valve 14; slowly open needle valve 15 then; the efficient antiseptic soup adds boiler water by regulating given flow through jet pump negative pressure mouth through pencil 13, closes all valves during drug withdrawal.
The advantage of the anticorrosion doser of this hot-water boiler:
1, it is poor to utilize boiler feedwater to pump intake pressure, through the by-pass flow pipeline, drives the jet pump operation, do not need that complicated control device do not need that additionaling power can be convenient and reliable efficient antiseptic soup adding boiler water;
2, the transparent scale that indicates of soup meter can show and measure the given dose that adds;
3, hot-water boiler uses efficient antiseptic anticorrosion, and same medicament is adopted in boiler operatiopn and blowing out, need not remove the corrosion that dissolved oxygen can be prevented block and other depolarizing agent.Anticorrosion more more effective than oxygen scavenger, when adopting oxygen scavenger, blowing out should add anti-corrosion measure in addition.Not only anticorrosion in the boiler operatiopn, and furnace shutdown period discharges water and all can effectively not prevent the corrosion of boiler and hot-water heating system with not discharging water.Operating cost can save 2/3rds, and prolonged boiler service life is more than three times.
This doser is simple in structure, and is easy to manufacture, low price, installation, operation, easy to maintenance, reliable operation, operating cost is low, and the dose that adds boiler can be regulated, and is intuitively readable, efficient antiseptic is nontoxic, and antiseptic effect is remarkable, is the anti-doser of a kind of desirable hot-water boiler.
The anticorrosion doser of this hot-water boiler can extensively be adapted to the anticorrosion of various hot-water boilers.
Embodiment:
The anticorrosion doser of PSJ type hot-water boiler
Soup meter, 2.4 liters of dischargeable capacitys, its scale are that 24 big lattice, every big lattice divide four little lattice.
Jet pump, 45 millimeters of external diameter ∮, 76 millimeters of length
Water pipe, liquid medicine pipe diameter Dg10 millimeter, pencil diameter Dg8 millimeter are joined corresponding bore valve, needle valve.
With 600,000 kilocalories/time hot-water boiler be example
Boiler brings into operation, and opens all valves, adds efficient anticorrisive agent soup, and flow is adjusted to per hour big lattice (1 liter) with needle valve, the boiler stage dosing 72 hours (72 liters) that brings into operation, after close all valves;
Boiler normally moves, operation sequence the same every day (24 hours) dosing 1 hour (1 liter);
Before the boiler shutdown, continuous dosing 24 hours (24 liters)
Behind the boiler shutdown: discharging water and not discharging water all to make boiler and hot-water heating system prevent corrosion;
300,000 kilocalories/hour boiler in this way, add dose per hour 1/2 big lattice (1/2 liter), 1,200,000 kilocalories/time boiler add dose per hour 2 big lattice (2 liters) be by that analogy.
