Specific implementation mode

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model It clearly and completely describes, it is clear that described embodiment is only the utility model a part of the embodiment, rather than whole realities Apply example.Based on the embodiments of the present invention, those of ordinary skill in the art institute without creative efforts The every other embodiment obtained, shall fall within the protection scope of the present invention.

As depicted in figs. 1 and 2, a kind of emission-control equipment described in the utility model, including the fine mistake of a kiln 1, one pottery Filter 2 and a chimney 3, the kiln 1 are connected to the fine filter 2 of the pottery with a downtake pipe W1, the pottery fibre filter 2 with One second exhaust pipe W2 is connected to the chimney 3.

The kiln 1 has a combustion chamber 11, can be placed in glass raw material (for example, silica sand, calcium carbonate, sodium carbonate etc.) In the combustion chamber 11, and make the glass raw material melted at a high temperature of about 800 DEG C formation melt slurry, with further at Shape glass finished-product.

It is fine that exhaust gas caused by the glass raw material high-temperature fusion can flow to the pottery via the downtake pipe W1 Filter 2.In this present embodiment, the emission-control equipment of the glass industry preferably can include a first heat exchanger H1, institute It states first heat exchanger H1 and is set to the downtake pipe W1, the temperature of the exhaust gas is reduced to about 380 DEG C, make described Exhaust gas can enter the fine filter 2 of the pottery at temperature appropriate, can not only maintain the good mistake of the pottery fibre filter 2 Effect is filtered, and denitration catalyst of the excessively high temperature (for example, 380 DEG C or more temperature) to the fine filter of the pottery 2 can be avoided Particle 212 causes attenuating or the failure of efficiency (in detail as following).

The downtake pipe W1 can have an a denitrfying agent input port O1 and desulfurizing agent input port O2, the denitrfying agent The input port O1 and desulfurizing agent input port O2 is respectively positioned between the fine filter of the kiln 1 and the pottery 2, and respectively with for Work person is by a denitrfying agent (for example, the amino reductives such as ammonia, liquid ammonia, ammonium hydroxide or urea) and a desulfurizing agent (for example, niter The alkaline agents such as ash, sodium bicarbonate and sodium hydroxide) it puts into the downtake pipe W1, and be put into the downtake pipe W1 Denitrfying agent and desulfurizing agent can then be driven by the exhaust gas, flow to the fine filter of the pottery along the downtake pipe W1 2.In this present embodiment, the desulfurizing agent input port O2 is located between the denitrfying agent input port O1 and pottery fibre filter 2, Only the denitrfying agent input port O1 can also be set to the desulfurizing agent input port by this creation tool usually intellectual depending on demand Between O2 and pottery fibre filter 2, do not limited in this.

The pottery fibre filter 2 can include the fine chimney filter 21 of at least one pottery, and fine 21 system of chimney filter of the pottery is by multiple ceramic fine Dimension 211 and multiple denitration catalyst grains 212 are collectively formed, and the multiple denitration catalyst grains 212 are attached to the multiple pottery The surface of porcelain fiber 211 makes the multiple denitration catalyst grains 212 may be uniformly distributed in the fine chimney filter 21 of the pottery, promotes institute State the contact area of multiple denitration catalyst grains 212 and the exhaust gas.

In this way, the fine chimney filter of the pottery 21 be other than it can filter the dust removed in the exhaust gas, in the exhaust gas Nitrogen oxides can be under the action of the denitrfying agent and denitration catalyst grains 212, with selective catalytic reduction (SCR) It is converted into nitrogen that is nontoxic and being directly discharged in air, and the oxysulfide in the exhaust gas then can be in the desulfurization It is converted into solid calcium sulfate or gypsum (calcium sulphate dihydrate) under the action of agent, and is filtered off by pottery fibre chimney filter 21 It removes, thus in the fine filter 2 of the pottery, the denitrfying agent through denitrfying agent input port O1 inputs and through the desulfurizing agent input port O2 input desulfurizing agent it is coefficient under, the pollutant (for example, dust, nitrogen oxides and oxysulfide) in the exhaust gas It can efficiently be removed, and a net gas can be formed and flow to the chimney 3 via the second exhaust pipe W2.

The net gas directly can flow to the chimney 3 via a second exhaust pipe W2, and be emitted into air；Only due to Temperature via 2 filtered air of the fine filter of pottery is about 330 DEG C, thus in this present embodiment, the glass industry is given up Gas disposal dress includes a second heat exchanger H2, and the second heat exchanger H2 is set to the second exhaust pipe W2, with further The temperature of the net gas is reduced, so further the thermal energy entrained by the net gas can be recycled, and heat can be promoted The organic efficiency of energy.

In summary, it in the utility model emission-control equipment, by the setting of the fine filter of the pottery, can effectively filter Remove the dust in exhaust gas caused by glass raw material high-temperature fusion, and by the denitrfying agent input port be attached to it is the multiple Conversion of nitrogen oxides in the exhaust gas can be effectively nothing by the setting of multiple denitration catalyst grains on the surface of ceramic fibre Poison and the nitrogen that can be directly discharged in air, while by the setting of the desulfurizing agent input port and the fine filter of the pottery, Effectively by the oxysulfide conversion solid-state in exhaust gas and can the calcium sulfate or gypsum removed can be filtered easily, so Efficiently to remove the pollutants such as dust and sour gas in the exhaust gas.

In the utility model emission-control equipment, it is only necessary in the downtake pipe be equipped with the denitrfying agent input port and The desulfurizing agent input port, and it is attached with the multiple denitration catalyst grains in the surface of the multiple ceramic fibre, you can with The sour gas in the exhaust gas is efficiently removed, desulfurization part complicated in known emission-control equipment and denitration can be exempted The setting of part can so reach simplified device and reduction device setup cost and other effects.

In addition, the utility model emission-control equipment, it can be by the first heat exchanger and the second heat exchanger Setting, recycle the thermal energy in the exhaust gas and the net gas, energy waste caused by reducing thermal energy loss may further reach The effect of being recycled to energy recovery.

The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this The spirit of utility model is interior with principle, and any modification, equivalent replacement, improvement and so on should be included in the utility model Protection domain it is interior.
