Abstract

The utility model relates to a glass melting furnace seals flue, it forms heat dissipation channel (3) and communicates with each other with the atmosphere to be equipped with spaced chamotte brick bar buttress (2) on concrete floor (1), lay flue bottom plate steel deck (4) on chamotte brick bar buttress (2), flue side wall steel deck (5) is connected to the both sides of flue bottom plate steel deck (4), stack arch top steel deck (6) is connected to the upper end of flue side wall steel deck (5), lay chamotte brick bottom plate layer (7) in proper order on flue bottom plate steel deck (4), insulating brick layer (8) and chamotte brick layer (9), be equipped with flue wall body (10) respectively in flue side wall steel deck (5) inboard, it is equipped with stack arch top (11) to push up steel deck (6) inboard at the stack arch. The utility model has the advantages that: owing to adopt the steel sheet to connect the cladding to the full weld of flue, to have stopped in the outside air gets into the flue, assurance for the waste heat utilization of flue gas provides the flue -gas temperature has promptly reduced the fan power of carrying the flue gas again.

Description

A kind of glass melter sealing flue

technical field:

The utility model relates to glass manufacturing area, the sealing flue particularly in a kind of glass melter.

background technology:

Flue-gas temperature in glass melter flue generally can reach 400 ~ 600 DEG C, flue is laid on concrete floor, heat resisting temperature due to normal concrete is no more than the restriction of 200 DEG C, usual solution is all that concrete floor adopts heat resistance concrete, then on heat resistance concrete base plate, lay multilayer common brick add insulating brick, use clay brick near fume side, three kinds of bricks superpose in order to isolated flue gas to concrete heat transfer.If it is on the low side that the number of plies laid by common brick, insulating brick, clay brick, concrete floor will be subject to Thermal cracking or efflorescence, causes Groundwater infiltration, has a strong impact on production; If common brick, insulating brick, clay brick are laid, the number of plies is a lot, and one side increases cost, adds the load of concrete floor, and under flue base plate central zone, surface concrete still can be in hot environment on the other hand.

In order to solve the problem, flue adopts built on stilts mode of laying one deck heat dissipation channel on concrete floor, greatly reduces the heat transfer of flue-gas temperature to concrete floor.But must dilatation joint be left when flue body of wall and base plate are built by laying bricks or stones, for flue gas by the rear space reserving expansion to brick body.Affect by various factorss such as temperature, dilatation joint differs swollen reality surely, and always has the place that mortar is not full of when building by laying bricks or stones between brick and brick, and the probability that above-mentioned phenomenon especially occurs when flue floor level makes somebody a mere figurehead laying is more.Because flue gas in flue is negative pressure state, this just causes extraneous air seepage flue inner, flue-gas temperature is caused to decline, the energy conservation project generated electricity is carried out for utilizing fume afterheat, bring the problem of inefficiency, utilize even without fume afterheat, also can reduce the power of fume emission, increase the difficulty that furnace pressure regulates.

Utility model content

The purpose of this utility model is exactly to overcome the base plate weak heat-dissipating of glass melter flue structure existence in prior art, the defect of flue stopping property difference, a kind of glass melter sealing flue provided.

the utility model have employed following technical scheme:

A kind of glass melter sealing flue, comprise concrete floor, concrete floor is established spaced clay brick bar shaped pile up neatly, form heat dissipation channel between adjacent clay brick bar shaped buttress and communicate with air, it is characterized in that: on clay brick bar shaped buttress, lay flue Bottom Board Steel flaggy, the both sides of flue Bottom Board Steel flaggy connect flue side wall steel plate layer respectively, the upper end of flue side wall steel plate layer connects stack arch top steel plate layer, flue Bottom Board Steel flaggy lays clay brick backplane level successively, heat insulation brick layer and undercloak, flue body of wall is respectively equipped with inside flue side wall steel plate layer, stack arch top is provided with inside the steel plate layer of stack arch top.

the utility model has the advantage of:owing to adopting steel plate to connect coated to the full weld of flue, stopped extraneous air and entered in flue, namely the UTILIZATION OF VESIDUAL HEAT IN for flue gas provides the guarantee of flue-gas temperature, additionally reduces the blower fan power of supplied flue gases.

accompanying drawing illustrates:

Fig. 1 is sectional view of the present utility model.

Embodiment:

As shown in Figure 1, a kind of glass melter sealing flue that the utility model passes through, comprise concrete floor 1, concrete floor 1 is provided with the clay brick bar shaped buttress 2 kept at a certain distance away, form heat dissipation channel 3 between adjacent clay brick bar shaped buttress 2 and communicate with air.Flue Bottom Board Steel flaggy 4 laid by clay brick bar shaped buttress 2, and the both sides of flue Bottom Board Steel flaggy 4 weld flue side wall steel plate layer 5 respectively, welding stack arch top, the upper end steel plate layer 6 of flue side wall steel plate layer 5.Flue Bottom Board Steel flaggy 4 is laid clay brick backplane level 7, heat insulation brick layer 8 and undercloak 9 successively, inside flue side wall steel plate layer 5, is respectively equipped with flue body of wall 10, inside stack arch top steel plate layer 6, be provided with stack arch top 11.Namely steel plate is adopted to manufacture the flue shell of a sealing, on the flue body of wall of laying flue base plate, both sides and stack arch top in flue shell, the final melting furnaces flue forming a front cover.

Claims

1. a glass melter sealing flue, comprise concrete floor (1), concrete floor (1) is established spaced clay brick bar shaped pile up neatly (2), form heat dissipation channel (3) between adjacent clay brick bar shaped buttress (2) and communicate with air, it is characterized in that: in clay brick bar shaped buttress (2) upper laying flue Bottom Board Steel flaggy (4), the both sides of flue Bottom Board Steel flaggy (4) connect flue side wall steel plate layer (5) respectively, the upper end of flue side wall steel plate layer (5) connects stack arch top steel plate layer (6), flue Bottom Board Steel flaggy (4) is laid clay brick backplane level (7) successively, heat insulation brick layer (8) and undercloak (9), flue body of wall (10) is respectively equipped with in flue side wall steel plate layer (5) inner side, stack arch top (11) is provided with in inner side, stack arch top steel plate layer (6).
