Abstract
Regenerative glass melting furnace, in particular for heating with low-calorific-value gas, such as producer gas, in which a substantially rectangular-bottomed melting vessel has glass outlets and nozzles (1) for hot air/gas mixture providing a heat source, which are arranged on the short sides (2) of the melting vessel and are each adjacent to a feed device (15) on the long side, and a homogenizing chute (4) with a transverse bottom outlet is arranged centrally and vertically across the top of the melting vessel. The furnace of the present invention is an ideal device to solve the existing problems, even when producer gas is used, due to its simple structure and ability to produce high quality glass.
Description
The present invention relates to the back-heating type glass furnace, be particularly related to and use lower calorific value coal gas, producer gas heated glass smelting furnace for example, in this stove, the molten groove of substantial rectangular bottom surface has the admission port (nozzle) of the warm air/coal gas gas mixture of glass outlet (opening) and heating usefulness.
Verified, under the situation of the operation that guarantees glass furnace by coal gasification, producer gas is being successful aspect the driving glass furnace.The shortcoming of using producer gas is its lower calorific value and the lower flame temperature that causes thus, and this makes criticizes furnace charge for fusing and require big melted surface area.
Task of the present invention provides a kind ofly to be compared with the smelting furnace that drives with producer gas so far, presents the glass furnace of the efficient of improvement, and, in this smelting furnace, specific storage, promptly, the capacity of the molten rooved face area of unit is improved, and simultaneously, produces higher-quality glass.
This problem has been given solution by the present invention by the smelting furnace of creating design as follows, that is, with the short side of each nozzle arrangement at molten groove, and feed appliance is arranged in the end near the long side of nozzle; Be arranged at the center and vertically across this molten groove be homogenizing part with horizontal outlet, the bottom surface of this part is on the significantly lower height in the bottom surface in neighbour near molten bath.What be arranged in each side of homogenizing part is partition wall.
Be not sucked into the homogenizing part in order to ensure batch furnace charge, can form step on the bottom surface of homogenizing part partition wall back, this step has the some eyelets that are used to be blown into air; In order to simplify the structure of partition wall, form the zone purification at this above two partition walls, between step with some pores and two partition walls, can arrange the intermediate step of a moderate height.
In order to safeguard necessary, the plug flow in homogenizing part from the top to the bottom of homogenization process, and avoid convection current, near the adiabatic insulation homogenizing part bottom surface to small part can remove, so that guarantee the cooling of the glass flows of avaling.
Be useful on regenerative chamber according to stove and accessory of the present invention to the air that fired and coal gas heating, it is worked effectively as follows, promptly, warm air and coal gas gas mixture can alternately be sent to from each short side, thereby, in all cases, waste gas is discharged from another short side, so just can skim over the whole surface of glass.That side that batch furnace charge then advantageously leaves molten groove from waste gas is sent to.
In following each paragraph, will describe in detail to being applied to embodiments of the invention by means of accompanying drawing.In the accompanying drawing:
Fig. 1 is the vertical cross section of whole glass furnace of the present invention;
Fig. 2 be according to the whole smelting furnace of Fig. 1, in the horizontal sectional drawing at the molten groove height place of glass; And
Fig. 3 is the vertical cross section of whole glass furnace, and wherein, two side direction homogenizing of arch furnace roof partly tilt.
By being equipped with the regenerative chamber of firing the air and the routine of the coal gas of heat that is used to produce heat, the glass of substantial rectangular bottom surface melts groove, and the various necessary part of the molten groove of glass is formed according to glass furnace of the present invention.
The coal gas that fires air and heat of heat is sent in short side 2, thereby in all cases, waste gas is discharged from relative side.
Be arranged at the center and vertically across molten groove be the homogenizing part 4 of skewed slot shape, be bordering on the homogenizing part near its bottom surface 6 is in and on the significantly lower height in the bottom surface of the melt portions 5 that is provided with.
The height of two partition walls 8 is to be provided with like this, promptly, by adjusting time and temperature, after fusing batch furnace charge, can obtain the glass flows of optimum regime, and, before glass sinks with the form of plug flow, in homogenizing part 4,, glass can be taken out from the homogeneous parts transversely without any the purifying that glass takes place under the convection current turbulent situation.
Two block walls 8 have the intermediate step 13 of pressing close to separately, and the latter is convenient to the formation of partition wall.What press close to this intermediate step 13 on the bottom surface of melt portions 5 is step 11, in this step, is provided for the air inlet port 12 of introducing air.
The bubble that derives from air inlet port produces air current flow, and its flow direction is opposite with the flow direction of batch furnace charge, thereby, prevent that any batch of furnace charge is sucked into homogenizing part 4 and the reduction glass quality.
The adiabatic insulation 16 of homogenizing part 4 can remove where necessary, so that regulate the temperature in the homogenizing part 4 as follows, that is, making the highest temperature is at the top, and following temperature-stable ground is descended.
Because the result of said temperature level has avoided forming convection current in homogenizing part 4, and glass sinks with the plug flow state in the homogenizing part.Therefore, laterally the glass that takes out has very high quality, and this normally can not reach in the stove with the heating of lower calorific value coal gas.
A kind of change shown in Fig. 3, wherein the arch furnace roof partly tilts to homogenizing.Because this structure design, reduced the radiative transfer between the part of the specific melt portions that has heated and the furnace charge of packing into.So just might further reduce the temperature that enters regenerative chamber waste gas, cause further improving thermo-efficiency, and make the heat conservation of regenerative chamber.
In order to utilize regenerative heat exchanger, must make stove cycle operation of the present invention.Warm air/coal gas gas mixture is sent to a short side 2, and waste gas is discharged from relative short side 2.After under the heat exchanger cooling, start the heat exchanger that has been reheated simultaneously of opposite side, so air and coal gas are sent to from another short side, waste gas is then discharged from that short side of originally once sending air and coal gas to.
In this way, guarantee that flame and waste gas skim over the molten groove of whole glass, thereby reach the optimum utilization of energy, simultaneously, only produce a spot of nitrogen oxide.Importantly, criticizing furnace charge sends in waste gas discharge side all the time.Because flame roughly exhausts at the center of molten groove,, therefore, there are more heats to be sent on the material in the stove so because the bigger temperature difference, the waste gas of new furnace charge top is subjected to much better than cooling than usually; Thereby, improved melting capacity and reduced the temperature of waste gas outlet.This causes reducing energy expenditure again.
In addition, because its simple structure and generation have the ability of higher-quality glass, even when using producer gas, be still the ideal equipment that solves existing problem according to smelting furnace of the present invention.
