Technical Field

The invention relates to the technical field of glass processing, in particular to a clarification tank of a glass kiln and the glass kiln.

Background

The glass kiln is an extremely important component in glass production. The glass melting furnace is generally divided into a melting section, a fining section and a cooling section, and the fining section and the cooling section are connected by a neck. The raw material is melted in the melting part, enters the clarifying part for clarification, and finally enters the cooling part through the neck for cooling.

In the melting section of a glass furnace, natural gas is generally injected into a lance as fuel to heat a glass raw material, so that exhaust gas such as insufficiently combusted natural gas inevitably remains in the melting section, and a part of the remaining exhaust gas is discharged through a flue and a part of the remaining exhaust gas is accumulated in a refining section by the gas pressure. Residual exhaust gas acting on the molten glass in the fining portion may cause the resulting glass article to develop color and reduce its transparency.

At present, in order to avoid the above situation, the opening degree of a large gate plate at the flue of the glass kiln is usually adjusted to discharge the waste gas such as natural gas which is not fully combusted, but the adjustment mode can lead the external cold air to enter the clarifying part, thereby influencing the production process of the glass.

Detailed Description

In the present invention, the use of directional terms such as "upper, lower, left and right" in the absence of a contrary explanation generally means that the directions shown in the drawings and the practical application are considered to be the same, and "inner and outer" mean the inner and outer of the outline of the component.

The invention provides a glass kiln clarification tank, which comprises a tank body for glass liquid to pass through and a waste gas displacement device 12 arranged on the side wall 10 of the tank body, wherein the waste gas displacement device 12 is configured to introduce hot air and/or hot inert gas into the tank body and discharge waste gas in the tank body through the hot air and/or hot inert gas. It can be understood that the glass furnace clarification tank is arranged at the downstream of a melting part of the glass furnace, the molten glass obtained in the melting part flows into the tank body for clarification, and the melting part is communicated with the tank body, so that residual waste gas such as insufficiently combusted natural gas in the melting part can enter the tank body. By arranging the waste gas replacement device 12 on the side wall 10 of the tank body of the glass kiln clarification tank, hot air and/or hot inert gas such as nitrogen can be introduced into the tank body, and the waste gas in the tank body such as residual insufficiently combusted natural gas flowing from a melting part can be discharged under the action of the hot air and/or the hot inert gas, so that the quality of molten glass cannot be influenced by the waste gas, the transparency of a finally obtained glass product is improved, and meanwhile, the waste gas replacement device 12 can ensure the pressure in the tank body to be stable. In addition, it should be noted that a neck portion is provided in the glass kiln downstream of the clarification tank, and the waste gas such as natural gas which is not sufficiently combusted is discharged in time by the waste gas replacement device 12, so that the glass raw material in the upstream does not flow to the neck portion and deposit on the neck portion by the flow of the waste gas, thereby improving the transparency of the final glass product.

As shown in fig. 1, an air inlet 102 may be opened on the side wall 10 of the tank body, the exhaust gas replacement device 12 may include an air inlet assembly 14 disposed at the air inlet 102, the air inlet assembly 14 may include an air inlet pipe 140 disposed at the air inlet 102 and capable of introducing air and/or inert gas into the tank body, and a first heating member 142 disposed on the air inlet pipe 140 and used for heating the air and/or inert gas, for example, an electric heating member may be selected as the first heating member 142. Thus, an external gas such as air and/or an inert gas such as nitrogen may be introduced into the gas inlet 102 through the gas inlet pipe 140, while the introduced gas may be heated by the first heating member 142. Preferably, hot air and/or a hot inert gas such as nitrogen is introduced into the gas inlet pipe 140 while the introduced gas is heated by the first heating member 142 to achieve a desired temperature of the introduced gas and to maintain the temperature of the introduced gas.

The filter 143 may include a filter net or a filter membrane, and the structure thereof is not particularly limited as long as it can filter impurities from the air and/or the inert gas.

In order to better filter out impurities in the air and/or inert gas while also allowing stable introduction of the gas into the inlet pipe 140, the filter sleeve 141 may be divergent in a direction from a port near the first end to a port far from the first end.

Further, the air intake assembly 14 may include an air scoop 144, such as an induced draft fan, disposed on the air intake tube 140, and the air scoop 144 may be configured to direct air and/or inert gas toward the air intake 102. Wherein the air inducing member 144 may be disposed upstream of the first heating member 142 in the gas flowing direction.

For better heating of the introduced gas, the gas inlet assembly 14 may include a second heating member 148, such as a thermocouple, disposed downstream of the first heating member 142 in the direction of gas flow. In addition, in order to make the heated gas not easily dissipate heat, an insulating layer may be provided on an outer wall of the intake duct 140, for example, insulating cotton may be provided on an outer wall of the intake duct 140.

For smooth discharge of exhaust gas such as natural gas which is not sufficiently combusted, an exhaust port 100 for discharging the exhaust gas may be formed on the side wall 10 of the tank body, the exhaust gas replacement device 12 may include an exhaust assembly 16 disposed at the exhaust port 100, and the exhaust assembly 16 may include an exhaust pipe 160 disposed at the exhaust port 100. Further, an exhaust valve 162 may be provided in exhaust pipe 160, and exhaust valve 162 may be configured to control the amount of airflow directed from exhaust pipe 160.

In addition, a plurality of air inlets 102 may be formed in the side wall 10 of the tank body, and an air inlet module 14 may be provided at each air inlet 102, so that the gas is smoothly introduced into the tank body.

It should be noted that the tank body has a pair of opposite and spaced side walls 10, and preferably, a plurality of exhaust ports 100 and a plurality of air inlets 102 corresponding to the positions of the plurality of exhaust ports 100 are disposed on each side wall 10, wherein the exhaust ports 100 may be disposed above the air inlets 102, an exhaust assembly 16 may be disposed at each exhaust port 100, and an air inlet assembly 14 may be disposed at each air inlet 102, and it is understood that a plurality of exhaust gas replacement devices 12 may be disposed on each side wall 10.
