Abstract

A hook-shaped regenerator for glass furnace includes a parallel small furnace, a flue, a rider arch, an ash pool and an ash removal hole, characterized in that a parallel long flow channel and a short flow channel are also provided; one side of the top end of the long flow channel is communicated with the small furnace, one side of the top end of the short flow channel is communicated with the flue; and the long flow channel and the short flue channel are combined vertically to be hook-shaped, the lower end of which is communicated with the ash pool by the rider arch. Compared with the one-stage regenerator, the utility model increases the regenerative area, prolongs the heat exchanging process between the waste gas and the air, capable of reducing the temperature of the total flue from 350 DEG to 260 DEG, improving the heat recovery efficiency about 5%; compared with the three-stage regenerator, the utility model is superior in simple structure, low costs, small flow resistance, small occupying area with equivalent heat recovery effect; simultaneously, with the hook-shaped regenerator of the utility model, it is convenient for reconstructing the primary glass furnace of the one-stage regenerator for obtaining remarkable energy saving effect with low costs.

Description

A kind of hook regenerator that glass furnace is used

One, technical field

The utility model belongs to what glass and makes special-purpose kiln, is specifically related to be specially adapted to the regenerator of glass furnace.

Two, background technology

Regenerator is the important utility appliance that is used for reclaiming glass furnace waste gas heat.Existing glass furnace, what employing was maximum at present is the one-part form regenerator of " straight type " structure, it is made up of vertical two flow channels arranged side by side, high-temp waste gas and freezing air are gone against the stream from two flow channels respectively, realize waste gas and air heat exchange, reclaim in the waste gas heat and make into that the stove air themperature obtains the preheating raising.But this one-part form regenerator, waste gas and air can not carry out sufficient heat exchange, and the temperature that waste gas enters flue all about 350 ℃, taken away by waste gas by a large amount of heats.The syllogic regenerator of a kind of in addition " N type " structure, it is made up of two " N " font flow channels arranged side by side, the heat exchange principle is identical with the one-part form regenerator, waste gas and air have long heat exchanging process, so its recovery of heat effect is better than one-part form regenerator, waste gas enters the temperature of flue and can reduce to about 260 ℃.But this syllogic regenerator, complex structure, the cost height, gas-flow resistance is big, and floor space is also big simultaneously, its less at home and abroad employing.

Three, summary of the invention

At the defective that above-mentioned existing structure regenerator exists, propose a kind of hook regenerator of meter, make it to be used for glass furnace, effective to the recovery of heat of waste gas, simple in structure, cost is low, is convenient to old furnace modification and applies.

Technical solution adopted in the utility model is as follows.

A kind of hook regenerator that glass furnace is used includes port arranged side by side, flue, bar arch, ashpit and ash removing opening, it is characterized in that: it also has long air passage arranged side by side and the runner of losing heart; Long air passage upper end one side and port) be communicated with, runner upper end one side of losing heart is communicated with flue; Long air passage is vertically combined closely into hook with the runner of losing heart, and the lower end is connected through bar arch and ashpit.

The hook regenerator of the utility model structure, compare with the one-part form regenerator, increased heating surface, prolonged the process that waste gas and air carry out heat exchange, the spent air temperture of main flue can be dropped to about 260 ℃ from 350 ℃, and heat recovery rate improves about 5% relatively; Compare with the syllogic regenerator, much simple in structure, it is few to consume material, and gas-flow resistance is little, and floor space is also little, and the recovery of heat effect can be suitable; Simultaneously, adopt the hook regenerator of the utility model structure, can implement to transform to the glass furnace of original one-part form regenerator easily, spend less money can obtain the effect of considerable energy saving consumption reduction, easy to utilize in glass work.

Four, description of drawings

Fig. 2 is the flat cutting structural representation of the utility model hook regenerator.

In the drawings, 1a, 1b-port, 2a, 2b-long air passage, 3a, the 3b-runner of losing heart, 4a, 4b-flue, 5-bar arch, the 6-ashpit, the 7-ash removing opening, the A-exhaust flow is to, B-air flow.

Five, embodiment

Further specify the concrete structure of the utility model hook regenerator and its accumulation of heat principle of work below in conjunction with accompanying drawing.

Its concrete structure is: a kind of hook regenerator that glass furnace is used, include port 1a, 1b arranged side by side, flue 4a, 4b, bar arch 5, ashpit 6 and ash removing opening 7, and it is characterized in that it also has long air passage 2a, 2b arranged side by side and lose heart runner 3a, 3b; Long air passage 2a, 2b upper end one side is communicated with port 1a, 2b, and runner 3a, 3b upper end one side of losing heart is communicated with flue 4a, 4b; Long air passage 2a, 2b vertically combine closely into hook with lose heart runner 3a, 3b, and the lower end is connected through bar arch 5 and ashpit 6.

Its accumulation of heat principle of work is: high-temp waste gas A enters long air passage 2b from port 1b, flows into the runner 3b that loses heart through same column bar arch 5 and ashpit 6 again, discharges from flue 4b at last; Meanwhile, freezing air B enters the runner 3a that loses heart from flue 4a, flows into long air passage 2a through same column bar arch 5 and ashpit 6 again, enters glass furnace and fuel mix burning from port 1a at last.In this long and short flow channel arranged side by side, air and waste gas are gone against the stream and are realized the heat recovery function of air to waste gas.Every 20～30 minutes, flow direction of waste gas and air inerchange and passage, that is: waste gas turns to from flue 1a from port 1b and enters, and air turns to from port 4b from flue 4a and enters.So, go round and begin again and constantly carry out the heat exchanging process of glass furnace waste gas and air.

Claims
