Abstract
The utility model discloses a heating glass melter applied to the technology of pure oxygen and high-temperature air combustion; more than one pure oxygen combustion nozzle is arranged on the side wall of the melter at the batch molten glass area in a melting end, or the nozzles can be arranged at two sides thereof and the positions of the pure oxygen combustion nozzles are arranged in a staggering way; more than a pair of heat accumulating type high-temperature air combustion (HTAC) devices are arranged at two side walls of the melter at the glass classification homogenization area in the melting end, and the positions of the heat accumulating type high-temperature air combustion (HTAC) devices are arranged symmetrically.
Description
Technical field
The utility model relates to a kind of glass melter, especially a kind of pure oxygen and HTAC (high-temperature air burning) technology heated glass melting furnaces.
Background technology
The glass manufacturing has history in 5000.With the firewood be fuel, the manufacture method of melten glass admixtion has continued for a long time in the mud jar.The brother of Siemens had built the coal-fired tank furnace of continous way in 1867.After 1945, glass melter develops rapidly.
Glass melter is the Thermal Equipment of fusion cast glass, and glass smelting is one of main process during glass is made.It is very big to quality, output and the cost impact of product to found the reasonableness of speed and melting system.
Glass melter (especially large tank furnace used) heat accumulating types that adopt must have commutating device more, and each stage of founding carries out at the different sites of kiln.Admixtion is by the dog-house input, at the traveling process of fusing of melting end experience and glass metal clarification homogenizing.Most defective of existing glass melter is: complex structure, floor space are greatly, glass smelting speed is slow, the environmental protection effect is poor, be difficult to produce fine glass.
Summary of the invention
The purpose of this utility model provides a kind of pure oxygen and High Temperature Air Combustion heated glass melting furnaces of new structure, and it can improve efficiency of combustion and realize quick molten glass admixtion.
For achieving the above object, the utility model is taked following design:
A kind of pure oxygen and High Temperature Air Combustion heated glass melting furnaces: the melting end of melting furnaces comprises the molten-glass pool of bottom and the flame space on top; Form at the batch melting glass of melting end on the melting furnaces side wall in zone an above full-oxygen combustion nozzle is set; On the melting furnaces side wall of the glass clarifying homogenizing zone of melting end, a pair of above heat accumulating burner capable is set.
The utility model has the advantages that: it is simple in structure, and is safe and reliable, improves efficiency of combustion, and fuel saving reduces the NOx quantity discharged significantly, reduces the fixed cost investment and saves the factory building place.

Fig. 3 is the structural representation (left view) of glass melter shown in Figure 1
Embodiment
As Fig. 1, Fig. 2 and shown in Figure 3, the utility model pure oxygen and High Temperature Air Combustion heated glass melting furnaces melting end are mainly constituted by molten-glass pool 1, flame space 2, full-oxygen combustion nozzle 3, discharge flue 4, heat accumulating type HTAC device 5 and the reversing system 6 of bottom, and the front and back of melting end can be divided into batch melting glass and form and two zones of glass clarifying homogenizing.
The main improvement of the utility model glass melter is: form on the regional melting furnaces side wall at melting end batch melting glass several (more than one) full-oxygen combustion nozzles 3 are set: be provided with several to (more than a pair of) heat accumulating type high-temperature air burning (HTAC) device 5 on the melting furnaces side wall in melting end glass clarifying homogenizing zone.
Melting end batch melting glass form the zone the melting furnaces side wall on full-oxygen combustion nozzle 3 is set, both can be on monolateral sidewall, to be provided with, also setting simultaneously on the sidewall of both sides, and both sides is provided with the position of full-oxygen combustion nozzle staggers mutually for good, is beneficial to homogeneous heating.
High-temperature air burning (HTAC) device 5 is set on the melting furnaces both sides side wall in melting end glass clarifying homogenizing zone, and the HTAC device timing reversing burning on both sides is in accumulation of heat and heat release alternation state.Setting position is good symmetrically, is beneficial to abundant burning.
The utility model forms the zone at the batch melting glass of melting end and adopts pure oxygen combustion technology, makes it have efficient burning, melt and reduce the effect of NOx fast; Adopt high-temperature air burning (HTAC) technology in glass clarifying homogenizing zone, be characterized in: (1) adopts regenerator flue gas retrieving arrangement, alternately switches air and flue gas, and (heat interchanging areas such as Ceramic Balls or honeycomb are greater than 200m to make its heat storage of flowing through efficiently
2/ m
3), can reclaim the physics heat of high-temperature flue gas to greatest extent, thereby realize save energy significantly; (2) by organizing combustion with meagre oxygen, expand the flame zone, made kiln temperature be evenly distributed; (3) combustion with meagre oxygen greatly reduces the discharging of NOx in the flue gas.
The utility model forms the zone at glass melting, adopts the full-oxygen combustion system; Adopt the HTAC firing system in glass clarifying homogenizing zone.Effective combination of two kinds of combustion systems can realize the effect of high-quality, efficient, energy-conservation, reduction of discharging, environmental protection.
Claims (5)
