Description

Dismountable regenerator

Technical field

The utility model relates to a kind of heat-accumulating industrial furnace, a kind of regenerator of combustion gas or air that provides in this stove is provided (is called again: heat-accumulating burner).

Background technology

In the industrial combustion furnace system, regenerative combustion technology for air, gas-preheating behind high temperature (being generally more than 800 or 1000 degree), spray into the stove internal combustion, generally adopt regenerator.

Regenerator is to be installed on the industrial furnace furnace wall, the environment for use temperature is very high, main effect is that combustion gas or air enter waste gas eliminating in stove burning and the stove, the two is circulation alternately, and the temperature of waste gas is up to 1250 degree, and the temperature of air, combustion gas is generally more than 800 or 1000 degree, and the pressure of combustion gas and air is about 0.005Mpa, the pressure of waste gas is negative approximately 0.005Mpa, and regenerator needs never to allow the leakage of the least bit in this abominable condition of work lower seal work.

Regenerator can be divided into two spaces: one is the burner space, a space of being made up of burner block; The space of being made up of burner block is near in the stove.

The technology that adopts is at present: a kind of is that burner and burner block is integrated poured as one.

But this mode is because whole regenerator has the temperature difference of spending 1000 at length direction more, and burner block can cause longitudinal crack because of more excessive thermograde, reduces the service life of regenerator.

Another kind is divided into burner and burner block two parts with regenerator, burner block directly is placed on the furnace wall refractory material, burner adopts Type of Welding with being connected of furnace wall steel construction, adopt the high temperature fiber jam-pack between burner and the burner block, water the material feeding sealing with sealing pug or furnace wall in the groove, furnace wall waters material feeding burner and burner block is combined closely; But the problem that this structure exists is:

Because expanding with heat and contract with cold of refractory material, burner block cause the appearance gap between burner block and the burner along with moving of furnace wall refractory material; Owing to such gap occurs, the air of overflowing from burner and burner block gap, combustion gas diffuse to the furnace wall steel plate around burner, cause that steel plate burns red stain shape;

Also have because the furnace wall refractory material ftractures, and air, the combustion gas of overflowing from burner and burner block gap diffuses to the insulation material outside the furnace wall refractory material, causes that insulation material burns, furnace wall steel plate large tracts of land is burnt red, even burns with anger outside furnace wall; The damage that causes thus can't be changed, can only dismantle furnace wall steel plate and refractory material.

Summary of the invention

The utility model technical issues that need to address have provided a kind of dismountable regenerator, are intended to solve above-mentioned defective.

In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:

The utility model comprises the burner of being with box hat, combustion gas, air intlet, combustion gas, air outlet slit, interior dress floater guide block and heat storage; Also comprise the burner block of being with box hat; The burner block of described band box hat is fixed by the sealing installed part and the burner of band box hat; Between the burner block of being with box hat and interior dress floater guide block and heat storage, also comprise first refractory material, between the burner of being with box hat and interior dress floater guide block and heat storage, also comprise second refractory material; Comprise a seal between described first refractory material and second refractory material;

Compared with prior art, the beneficial effects of the utility model are: easy for installation, sealing is reliable, long service life and be easy to change.

Description of drawings

Fig. 1 is a structure cutaway view of the present utility model;

Fig. 2 is a K place enlarged drawing among Fig. 1;

Fig. 3 is will be with the burner block of box hat and the fixing sealing installed part structure chart of burner of band box hat among Fig. 1;

The specific embodiment

Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described in further detail:

By Fig. 1, Fig. 2, Fig. 3 as seen: the utility model comprises the burner 1 of being with box hat, combustion gas, air intlet 2, combustion gas, air outlet slit 4, interior dress floater guide block and heat storage 3; Also comprise the burner block 5 of being with box hat; The burner block 5 of described band box hat is fixing with the burner 1 of band box hat by sealing installed part 6; Between the burner block 5 of being with box hat and interior dress floater guide block and heat storage 3, also comprise first refractory material 7, between the burner 1 of being with box hat and interior dress floater guide block and heat storage 3, also comprise second refractory material 8; Comprise a seal 9 between described first refractory material 7 and second refractory material 8;

The burner block 5 of described band box hat fixedly is by the sealing gasket between nut bolt 61 and the nut bolt 62 flange on burner 1 and burner block 5 junctions to be fixed by the burner 1 of sealing installed part 6 and band box hat;

Described sealing gasket 62 is to adopt pyrographite pad or a kind of high-temperature seal adhesive;

Described seal 9 comprises that a resistant to elevated temperatures ceramic fiber paper 91 and one are between ceramic fiber paper 91, around the resistant to elevated temperatures ceramic fibre rope 92 of interior dress floater guide block and heat storage 3;

Because the burner block 5 of band box hat is nearer from stove, the fire resistance of first refractory material 7 is better than second refractory material 8.

Because burner block is made the band box hat, is connected with the burner of band box hat, by seal, sealing installed part it is sealed again, the utility model had both accomplished that sealing was better, in the needs replacing, can be easy to its dismounting especially.
