Abstract

The invention provides a plasma catalysis combustion energy saving paint, which is a high temperature resisting catalyst paint, which solves the problem of low combustion efficiency of the grate furnace. The product is a surface coating suitable for various boilers and kiln inner liner furnace building materials. The paint is coated on the surface of the inner liner refractory material on the periphery of the hearth of the kiln or furnace, and the dirty coke on the refractory material surface needs to be cleaned before coating, so that the flat and clean mother material is exposed. And then the surface is spray-coated and brush-coated with the catalyst paint, and after drying the furnace can be ignited for usage. The invention has the beneficial effect that thermal efficiency of the kiln or furnace is increased by 5-10%, and the coal saving rate is more than 10%.

Description

Plasma catalytic combustion energy saving coating

Technical field

The present invention relates to a kind of resistant to elevated temperatures catalyst ink.Be applicable to the top coat of various boilers, inner lining of kiln furnace building material.

Background technology

As the boiler of fuel and its combustion system of kiln three kinds of suspension combustion, Boiling Combustion and grate firings are arranged with coal.Wherein boiler and the kiln quantity in the grate firing mode is maximum, accounts for about 80% of stove total amount.But with regard to thermo-efficiency, grate firing is again minimum in three kinds of combustion systems, on average has only about 65%.Trace it to its cause mainly is that grate firing stove efficiency of combustion in three efficient forming boiler thermal output is minimum.These three kinds of combustion systems of all the other heat exchange efficiencies and thermal equilibrium efficient all are much the same.Thereby wanting to improve the thermo-efficiency of grate furnace, key is to improve the efficiency of combustion of grate furnace.

Prior art is from optimizing the cloth coal, upgrade, reasonable wind distribution, raising wind-warm syndrome and many-sides such as arch technology and membrane wall technology are improved and are improved, but because the restriction of combustion equipment and combustion conditions, the problem that the grate furnace efficiency of combustion is low is never solved at all.

Summary of the invention

In order to solve the low problem of grate furnace efficiency of combustion.

The technical solution adopted for the present invention to solve the technical problems is: the present invention is by a large amount of for many years practices, be coated with the last layer high temperature catalyst on grate furnace inner lining refractory surface, the combustion plasm(a) that exists in the grate firing is combined with catalysis technique, make burner and catalyticreactor coexist as one, hew out a brand-new raising grate firing boiler and the approach of furnace heat efficiency.

The burner of grate firing mode-and burner hearth in have the low-temperature burning plasma body.The burning of coal important behaviour is gasification, and combustion, and products of combustion is high-temperature flue gas, and a part of gas is ionized in high-temperature flue gas, produces atom, molecule and the free radical etc. of ion, high-energy electron, excited state.When catalyzer insert plasma body all in the time, electron energy, physical parameter such as electron density and power is subjected to the influence of catalyzer, particle (electronics, excited atom and ion) is driven catalyst surface out of, granules of catalyst is polarized, and the formation secondary electron emission, will form field intensity on the surface and strengthen the district.By transfer transport or oxygen transmission katalysis is reached by catalytic gas or solid surface, like this under the dual synergy of plasma body and catalysis and in organically combining, accelerated the various reactions in the combustion processes, made the speed of response of gas-solid two phase combustion all obtain accelerating.Be able to efficient burning, just improved efficiency of combustion greatly.

The preparation of coating: being base material with the high-temperature agglomerant, is Primary Catalysts with basic metal, alkaline-earth metal and transition metal oxide, makes finished product coating through stirring.Coating is applied over inner lining refractory surface around the burner hearth of stove, and dirty Jiao of reply refractory surface clears up before applying, and exposes smooth clean mother metal.Again catalyst ink is sprayed or brushes in its surface, can put stove after drying and use.

The invention has the beneficial effects as follows: stove thermo-efficiency improves 5%-10%, and coal saving rate reaches more than 10%.

Embodiment

Plasma catalytic combustion energy saving coating is applied over inner lining refractory surface around the burner hearth of stove, and dirty Jiao of reply refractory surface clears up before applying, and exposes smooth clean mother metal.Again catalyst ink is sprayed or brushes in its surface, can put stove after drying and use.
