Description

Two-sectional heat-exchanging double-arc glass tank furnace

The utility model relates to a kind of glass furnace, particularly relates to the two arch cell furnaces of a kind of two sections heat exchange types.

The two arch cell furnaces of traditional heat exchange type are to connect a Heat Room in the melting furnaces back, reclaim the heat in the flue gas, in order to warm-up combustion-supporting air, i.e. and secondary air.Owing to be subjected to factory building condition, molding technological condition, as the influence of tear drop height, its effective heat exchanging segment is short.General vertical countercurrent flow section is about 5-7 rice, and particularly in the more shallow place of ground water table, the Heat Room basis is dug to be gone down, effectively heat exchanging segment is then influenced bigger, thereby flue gas leaves the temperature height of Heat Room, and the heat recuperation in the flue gas is few, and the secondary air preheating temperature is low.Existing besides ceramic recuperator poor air-tightness is particularly advanced the secondary air channel of melting furnaces and the wind quirk before the flue gas flue, generally all is to build by box is brick.The box brick has the wedge head about being, and does not have the wedge head up and down, so the upper and lower plate structure that is not of masonry, the mud of seam easily leaks out after shrinking up and down, and this box brick structure is yielding in the high-temperature zone, thereby it is even more serious to leak out.So, traditional two arch cell furnaces, temperature of fusion is not too high, coal furnace particularly, energy consumption is big, and the effective thermal efficiency of kiln is low.

The purpose of this utility model is to provide a kind of two sections heat exchange types two arch cell furnaces.Short with the heat exchanging segment that overcomes the traditional glass tank furnace, the deficiency that the big thermo-efficiency of energy consumption is low.

The purpose of this utility model can reach by following technical measures, that is: two arch cell furnaces of this two sections heat exchange types, comprise melting furnaces, the port and the gas flue that connect also conducting with it, its key is a Heat Room, described Heat Room is in series by first section Heat Room and second section Heat Room, and the chamber is provided with one group of heat exchange device within it, is equipped with the inspection ash removing opening on the Heat Room wall of correspondence between per two row's heat exchange devices; Be provided with a secondary-air passage between first and second section Heat Room, this passage and heat exchange device inner chamber are conducted; Encircle in second section Heat Room, be provided with an exhaust steam passage, this passage and first and second section Heat Room are conducted.

Described heat exchange device is provided with the box brick of concavo-convex wedge head, single bonder, wind quirk front arch and square type spool tile letter by corresponding point of attachment up and down and connects to build by laying bricks or stones and form.

According to the two arch cell furnaces of two sections heat exchange types of above-mentioned formation, when coal gas by gas flue in port with the secondary air pre-mixing after during in the melting furnaces internal combustion, can produce high heat, its high-temperature flue gas enters first section Heat Room by two arch center-aisles and carries out heat exchange, and then enter second section Heat Room through exhaust steam passage and carry out heat exchange, because first, the setting of second section Heat Room has increased the length of heat exchanging segment effectively, can limit ground reclaim the heat in the flue gas, and the secondary air preheating temperature is improved greatly, thereby cut down the consumption of energy, improve melting furnace temperature, reach the purpose of this utility model.

The utility model compared with prior art, because air flows in the square type spool tile of thermal device from the bottom up, flue gas flows from top to bottom at each heat exchange device outside surface, forms counterflow heat exchange, the deficiency of having avoided dust in flue gas to result in blockage in the accumulation of square type spool tile inner chamber; Owing to be equipped with the inspection ash removing opening on the Heat Room wall of correspondence between per two row's heat exchange devices,, also be easy to remove even dust in flue gas is built up between two row's heat exchange devices; Because around the box brick, the box brick connects single bonder of usefulness with square type spool tile, and the counterparty of wind quirk front arch upwards leaves the wedge head, like this between box brick and the box brick, between box brick and the single bonder, between the two square type spool tiles up and down the wedge head be concavo-convex letter and connect, thereby form the integral slab block structure, add corresponding fixedly shape brick, make interchanger not yielding, adding does not have true straight joint between brick and the brick, be difficult for leaking out even mud shrinks yet, thereby overcome the problem of ceramic recuperator poor air-tightness; Owing to set up second section Heat Room, make effective heat exchanging segment lengthening, thereby the preheating temperature that makes secondary air is brought up to 1000～1200 ℃ by 600～800 ℃ of traditional kiln, even the coal gas that adopts simple and easy ladder producer gas generator to produce, furnace temperature also can be brought up to more than 1640 ℃ by former 1500 ℃, and coal consumption can descend more than 20%, is specially adapted to coal-fired middle-size and small-size glass furnace, and influenced by ground water table and other geologic condition, the place of not going down is dug on the Heat Room basis.

Embodiment of the present utility model is provided by the following drawings.

Fig. 2 is the enlarged diagram of Heat Room of the present utility model;

The two arch cell furnaces of two sections heat exchange types of the utility model, comprise melting furnaces 3, the port 2 and the gas flue 1 that connect also conducting with it, its key is a Heat Room, this Heat Room is in series by first section Heat Room 4 and second section Heat Room 6, and first section Heat Room 4 is conducted by two arch center-aisles and melting furnaces, at first and second section Heat Room inner chamber, be provided with one group of heat exchange device 8, be equipped with the inspection ash removing opening on the Heat Room wall of 8 correspondences of per two row's heat exchange devices; Between first and second section Heat Room, be provided with a secondary-air passage 7, heat exchange device 8 inner chambers in this passage and the Heat Room are conducted; Encircle in second section Heat Room, be provided with an exhaust steam passage 5, this passage and first, second section Heat Room are conducted.In addition, second section Heat Room outlet communicates with flue, chimney.

According to above-mentioned two sections heat exchange type cell furnaces making, its working process such as following:

One, coal gas is emitted heat in melting furnaces 3 internal combustion through gas flue 1 in port 2 Yu after the secondary air pre-mixing, and high-temperature flue gas enters first section Heat Room 4 through two arch center-aisles;

Two, to be aligned to the heat exchange device main body of several teams be that the rectangle spool tile is divided into several plume thighs and flows from top to bottom outside spool tile to the flue gas that enters first section Heat Room 4, heat is passed to secondary air by the rectangle spool tile, and the exhaust steam passage 5 through second section Heat Room 6 next door enters second section Heat Room 6 from above then;

Three, the flue gas that enters second section Heat Room 6 flows in second section Heat Room 6 from top to bottom with the flow velocity that is higher than in first section Heat Room 4, carries out heat exchange, enters flue then, chimney enters atmosphere;

Four, air then enters from second section Heat Room 6 bottom with opposite direction, flows from lower to upper in the rectangle spool tile, enters first section Heat Room 4 bottom from second section Heat Room top through secondary-air passage 7 then;

Five, enter the secondary air motion from the bottom up again of first section Heat Room 4, undertaken entering port 2 and coal gas mixed firing after the heat exchange by the rectangle spool tile.
