Description

TECHNICAL FIELD

[0001] The present disclosure relates to the technical field of glass production equipment, in particular to a smoke exhaust pipeline. BACKGROUND

[0002] Boron oxide has the effect of increasing the low-temperature viscosity of glass and reducing the high-temperature viscosity, and it also has a high heat absorption coefficient and a mass absorption coefficient, so it is usually necessary to add boron elements in the production of neutral borosilicate glass to make the produced neutral borosilicate glass have excellent chemical stability, a low thermal expansion coefficient and good mechanical properties, so as to be widely used in the fields of precision photoelectricity or pharmaceutical glass tube products.

[0003] In the production of neutral borosilicate glass, the temperature of the kiln is higher than the melting temperature of ordinary glass, about 1600℃ or more, and the content of boron oxide, the main component of neutral borosilicate glass, accounts for about 8%-12%, which is easy to volatilize at this temperature. The volatilized boron oxide and part of the particulate glass components will enter the flue with the high-temperature flue gas, and gradually crystallize to form accumulated dust and cold glass inside the flue as the flue temperature drops. Over time, it is easy to block the flue, thereby causing problems such as burning of the fan, difficulty in controlling the kiln pressure, etc. In addition, the accumulated dust formed by the crystallization of boron oxide is also easy to enter the dust removal system through the flue, causing problems such as blockage of the dust removal system.

[0004] The current common flue structure of glass kiln cannot effectively block or remove the volatilized and crystallized borides or particulate cold glass in the flue gas, so how to avoid the safety hazards caused by the crystallized borides or particulate cold glass long-term accumulation in the flue, leading to flue blockage, unstable internal pressure of the kiln or damage to the dust removal system, is a technical problem that needs to be solved.

[0030] Reference is made to the accompanying drawings Figure 1 and the drawings Figure 2 , embodiments of the present application propose a flue for discharging flue gas generated inside a kiln during the production of glass products, the flue comprising: a first dust collecting chamber 1, having a first accommodating space inside; a first flue 2 extending in a longitudinal direction, the top of the first flue 2 being configured to communicate with the inside of the kiln, the bottom of the first flue 2 being connected to the top of the first dust collecting chamber 1 and communicating with the first accommodating space; and a second flue 3 extending in a horizontal direction, one end of the second flue 3 being connected to the side of the first dust collecting chamber 1 and communicating with the first accommodating space; wherein the first accommodating space is at least partially located below the second flue 3, and the first dust collecting chamber 1 has a first dust cleaning opening on one side thereof, the first dust cleaning opening communicating with the first accommodating space and being located below the second flue 3; the first dust collecting chamber 1 comprises: a first chamber door 101 provided at the first dust cleaning opening.

[0031] Specifically, the smoke exhaust pipeline provided by the present disclosure comprises a first flue 2 extending in the longitudinal direction, a second flue 3 extending in the horizontal direction, and a first dust collecting cabin 1 for temporarily storing the volatile boride or the particulate cold-state glass deposit. The top of the first flue 2 is connected to the interior of the kiln, and the bottom of the first flue 2 is connected to the top of the first dust collecting cabin 1. One end of the second flue 3 is connected to the side of the first dust collecting cabin 1. The interior of the first dust collecting cabin 1 has a first accommodating space connected to the first flue 2 and the second flue 3 respectively. A first dust cleaning opening connected to the first accommodating space is arranged on the side of the first dust collecting cabin 1 below the second flue 3. A first cabin door 101 is arranged on the first dust cleaning opening. The high-temperature flue gas generated in the kiln can enter the first accommodating space of the first dust collecting cabin 1 through the first flue 2. The boride and other impurity crystals in the flue gas are deposited on the bottom of the first accommodating space. The remaining flue gas can be discharged from the first accommodating space through the second flue 3. After the flue gas discharge operation is completed, the first cabin door 101 arranged on the first dust cleaning opening is opened, and the deposited crystals or impurities on the bottom of the first accommodating space are cleaned by the dust cleaning tool 12 arranged on the first dust collecting cabin 1. The dust cleaning tool 12 can be similar to the structure of a fire tongs, and a metal scraper 1201 is welded on the working end of the dust cleaning tool 12. The deposited impurities on the bottom of the first accommodating space can be scraped off by the scraper 1201. Figure 2

[0032] According to the above, when producing neutral borosilicate glass, the flue gas generated in the kiln enters the first accommodating space of the first dust collecting cabin 1 through the first flue 2. In the process of entering the first accommodating space, the high-temperature flue gas is gradually cooled, the volatile boride contained in the flue gas is recrystallized, and the remaining impurity components such as cold-state glass form solid particulate deposits, which are accumulated on the bottom of the first accommodating space of the first dust collecting cabin 1. Therefore, the deposits are not accumulated in large quantities in the interiors of the first flue 2 and the second flue 3, which is not easy to cause the flues to be blocked. In addition, the deposits accumulated in the interior of the first accommodating space can be regularly cleaned through the first dust cleaning opening arranged on the first dust collecting cabin 1. The smoke exhaust pipeline provided by the present disclosure can effectively solve the safety problems caused by the fact that the crystallized boride or the particulate cold-state glass is accumulated in the flues for a long time, which causes the flues to be blocked, the internal pressure of the kiln to be unstable, or the dust removal system to be damaged.
