Description

The antiscale energy-saving heater

The utility model belongs to the heat-generating system of gas heater.

Gas heater is to be extensive use of by people, and the gas heater that China now uses just has several ten million platforms, and it has been indispensable part during people live.But the water heater of producing also comes with some shortcomings at present, defective on the heater structure of water heater makes the waste gas heat of discharge up to more than 200 degree, in use, because of can making in the heating element pipeline, quality problem ties incrustation scale, the thermal conductivity factor extreme difference of incrustation scale, than the little hundred times of metal, it can stop heat to be preached effectively.Heating element has just caused thermal loss because of structure problem of itself and the quality problem in the use.Heating element in use, as if things go on like this fouling in the pipeline, that still is a kind of accident potential.Several water heater explosions take place in area, 94 Zhengzhou in the end of the year, through the analysis expert demonstration, are exactly that quality problem causes water heater scaling dry combustion method explosion.It is the accident that causes because of incrustation scale that the article that the foreign city evening paper Hongkong and Macro version in 95 on October 14, has a piece of writing to be entitled as " crisis is turned to power " discloses the water heater explosion of area, Zhengzhou.Remove for solving incrustation scale, mainly still adopt acidic treatment at present, this is a kind of very passive method, and he allows incrustation scale produce clean again, and cleaning back a period of time again can fouling, takes a lot of work, takes the material contaminated environment like this; It is method preferably at present that magnetization is handled, and it can scale removal, can prevent fouling again, but the demonstration effect of this method can't immediate reaction, so also be difficult for for the moment being gone to be familiar with it by people.Present water heater does not all also design the magnetization apparatus for eliminating sludge in structure and goes, so water heater in use, and fouling is still a problem in the heating element pipeline.

The purpose of this utility model is to design a kind of antiscale energy-saving heater that can absorb waste gas heat and thoroughly prevent fouling in the heating element pipeline, plays energy savings and prevents acquired disposition heat loss and the security incident that the heating element pipeline scale causes in the use.

The purpose of this utility model is achieved in that a kind of antiscale energy-saving heater that is installed on gas heater firn-jet head top, contact successively by water inlet pipe, economizer bank, heat-generating pipe, outlet pipe and to communicate, economizer bank is centered around on the chamber wall fixing, heat-generating pipe and heat transfer sheet are combined into one, be located at the top, combustion chamber, in the heating element that is connected to form by heat transfer sheet and combustion chamber top periphery, have a magnetization apparatus for eliminating sludge on the water inlet pipe, loss of heat absorption tube of contacting between economizer bank and the heat-generating pipe and heat transfer sheet combination overlap the heat-generating pipe top.In the magnetization apparatus for eliminating sludge body two permanent magnets are set at least, polar configurations is a unlike pole, the S pole-face attracts to produce magnetic field mutually with the N pole-face, as long as effectively distinguishing from magnetic field, water flows through, the form of scale forming matter solid molecule changes, and causes its negative ions to take their own roads repulsion mutually and lose the ability of assembling fouling; The overlapping heat-generating pipe top that is located at of loss of heat absorption tube, purpose is to absorb waste gas heat.The heat absorption of loss of heat absorption tube is transmitted and is carried out than being easier to, because this moment, water temperature changed very little, the water temperature and the waste gas heat temperature difference are big, flow into heat-generating pipe again after this has just formed and has effectively utilized waste gas heat that water temperature is improved and heat, thereby realization utilizes the purpose of waste gas heat energy savings.Heat-generating pipe is the position that heating element improves the water temperature most critical because the thermal current that the combustion chamber produces be directly supply with it and with the heat transfer sheet of its combination, so the shape of pipeline has very big relation to absorbing thermal energy.Circular heat-generating pipe and heat transfer sheet combination heat absorption also are fine.Heat-generating pipe is made the heat absorption of arc combination heat transfer sheet, its effect can be made a world of difference, curved pipe and all will increase heating surface area with the heat transfer sheet of its combination simultaneously also can the prolongation thermal current and time of contact of curved pipe, the space length of the compressible caliber of curved pipe and the carrying out that quicken the heat transmission.The several characteristics of curved pipe can effectively improve the thermal efficiency of heating element.

Adopt such scheme, the loss of heat absorption tube is located at the heat-generating pipe top, can absorb waste gas heat effectively; Heat-generating pipe is made curved pipe, the one, can enlarge heating surface area, two can dwindle the space length of caliber and improve heat transfer speed, and this is to realize energy-conservation with structural variation.The magnetization apparatus for eliminating sludge is designed in structure and goes, can prevent from again in use to have eliminated simultaneously because of the contingent water heater bursting accident of incrustation scale hidden danger because of quality problem makes the heat loss that fouling produces in the heating element pipeline.This antiscale energy-saving heater, it is energy-conservation to have adopted various ways to realize, and one saves combustion gas surely to a great extent, for the user reduces expenses, for country economizes on resources, for our life protects environment.The antiscale energy-saving heater can possess these above-mentioned advantages, and it will become a kind of desirable heating element of gas heater from now on.
