Abstract

The utility model relates to boiler, in particular to a self purifying boiler with scale-prevention and descaling functions, which is provided with a boiler, an electromagnetic generator and an electrode bar and is characterized in that: the electrode bar is arranged on the internal wall of the boiler and is connected with the electromagnetic generator arranged outside the boiler through a conducting wire. During working, the electromagnetic generator generates electromagnetism conducted to the electrode bar arranged inside the boiler through a conducting wire to make the electrode bar generate high-frequency electromagnetic field; most water molecule in the boiler is combined into dimer from multi-molecule to reduce attractive force between molecules; meanwhile, under the action of high-frequency electromagnetic field, charged state of calcium ion and magnesium ion etc. also changes and polarity of ions is in systematic arrangement; moreover, attractive force between ions is broken and multi-ion complex is decomposed into single or single-chain ion complex so as to change crystallization condition and make crystalline solid uneasy to be adhered to tube wall, thereby realizing scale prevention and automatic descaling of boiler.

Description

The self-purification boiler

Technical field

The utility model relates to boiler, but the self-purification boiler of specifically a kind of antiscale, scale removal.

Background technology

We know, the heat-transfer surface of boiler very easily forms incrustation scale, its reason is owing to contain calcium in the water in the boiler, magnesium, materials such as silicon-dioxide, calcium, magnesium, materials such as silicon-dioxide at high temperature concentrate, reduced lime carbonate, the water solubility of carboxyl apatite and Magnesium Silicate q-agent etc., and with heat-transfer surface that water contacts on separate out a kind of material-incrustation scale that is insoluble in water, incrustation scale is the poor conductor of heat, when boiler has incrustation scale, incrustation scale has hindered the conduction of heat, thereby the consumption that has increased fuel, in addition, because making between the two, the temperature difference increases, body of heater is superheat state, increased the pressure of boiler, and then reduced boiler intensity, cause body of heater to break when serious, incrustation scale also may cause equipment jam etc., existing clean the boiler method is a kind of to be to adopt chemical medicinal method, promptly adopt hydrochloric acid or organic acid etc., when using hydrochloric acid, carried out chemical cleaning though added the dissolving with hydrochloric acid agent, but still some hydrochloric acid remains in the boiler, the salt acid ion changes in the middle of the steam during operation, body of heater is corroded, when using oxalic acid, though can dissolve incrustation scale, but the reductive agent effect that coexists with iron ion after the dissolving, then form Ferrox, Ferrox solubleness is low, can form precipitation, be attached to boiler surfaces, generation local corrosion as a result, also has a kind of antiscale, descaling method is to adopt the electronic treatment method, as the patent No. 93205385 " electronics antiscaling, descaling water treatment device ", it is made up of the main frame and the machine of paying, main frame is an electromagnetic generator, it is provided with housing, coil, circuit card, transformer etc., the machine of paying is provided with Steel Vessel, Steel Vessel is provided with water-in and water outlet, be provided with the copper rod (electrode bar) of overcoat plastics tubing in the Steel Vessel, copper rod is connected with output post on the electromagnetic generator through lead, heating medium water is entered by water-in, after the high-frequency electric field effect that electrode bar sends, flow out by water outlet, water outlet is connected with the water-in of boiler, the deficiency of this device is manufacturing cost and use cost height, WATER AS FLOW MEDIUM is handled insufficient, and boiler very easily forms incrustation scale, treatment capacity is little, can not satisfy the water supply of large-sized boiler.

Summary of the invention

The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, provide a kind of simple in structure, use cost is low, the water in the boiler is fully handled, and never produces the self-purification boiler of incrustation scale in the boiler.

The utility model can reach by following measure:

A kind of self-purification boiler is provided with boiler, electromagnetism generator, electrode bar, it is characterized in that electrode bar is located on the inwall of boiler, and electrode bar is connected with electromagnetism generator outside the boiler through lead.

The utility model is owing to be provided with electrode bar on boiler and wall that water contacts, electrode bar is connected with the electromagnetism generator through lead, make electrode bar send the higher frequency electromagnetic field, water molecules major part in the boiler is compound by polymolecular to be dimer, intermolecular magnetism weakens, simultaneously, calcium, the magnesium plasma is under the effect of higher frequency electromagnetic field, their state-of-charge also changes, and ionic polarity is series arrangement, and interionic attraction is destroyed, polyion complex body originally is divided into the ion complex body of single or chain, thereby cause the change of crystallization condition, be difficult for sticking on the tube wall, realized the antiscale and the automatic desludging of boiler.

Description of drawings

Fig. 1 is a structural representation of the present utility model, also is the structural representation of a kind of embodiment.

Embodiment

Below in conjunction with accompanying drawing the utility model is further described:

As shown in the figure, a kind of self-purification boiler, be provided with boiler 1, electromagnetism generator 2, electrode bar 3, boiler 1, electromagnetism generator 2, the structure of electrode bar 3 is same as the prior art, this does not give unnecessary details, be provided with electrode bar 3 in the boiler 1, can be provided with a plurality of electrode bars 3 in the boiler 1, electrode bar 3 is located on the inwall of boiler, also can be located on the inwall of boiler water tube, electrode bar 3 is connected with electromagnetism generator 2 outside the boiler 1 through lead 4, during the utility model work, electromagnetism generator 2 produces electromagnetism, electrode bar 3 in lead is passed to boiler 1, make electrode bar 3 send the higher frequency electromagnetic field, water molecules major part in the boiler 1 is compound by polymolecular to be dimer, intermolecular magnetism weakens, simultaneously, calcium, the magnesium plasma is under the effect of higher frequency electromagnetic field, and their state-of-charge also changes, ionic polarity is series arrangement, interionic attraction is destroyed, and polyion complex body originally is divided into the ion complex body of single or chain, thereby causes the change of crystallization condition, be difficult for sticking on the tube wall, realized the antiscale and the automatic desludging of boiler.

Claims

1, a kind of self-purification boiler is provided with boiler, electromagnetism generator, electrode bar, it is characterized in that electrode bar is located on the inwall of boiler, and electrode bar is connected with electromagnetism generator outside the boiler through lead.
