Abstract
A boiler for combusting leather making waste liquid comprises a burner, an upper drum, a lower drum, convection tube bundles arranged between the upper drum and the lower drum, a coal economizer and an air preheater, wherein a hearth of the burner is an all-film wall structure; a fluidized bed is arranged at the bottom of the hearth; fire-resistant wear-resistant pouring material layers are spread onto the inner side wall of the bottom of the hearth as well as onto the inner side walls of middle and lower parts of the hearth; spray pipes are arranged at the middle of the hearth, communicated with the internal cavity of the hearth, and inclined downwards; and the fire-resistant wear-resistant pouring material adopts pouring material containing chromium. According to the utility model, the all-film wall structure is arranged in the hearth of the boiler for combusting leather making waste liquid, so that leather making waste liquid is prevented from slagging and adhering to the film wall when the combustion temperature of the leather making waste liquid is too high; the downwards-inclining spray pipes are arranged at the middle of the hearth, and a spray gun can be inserted into one of the spray pipes for spraying leather making waste liquid into the hearth, therefore the complete combustion of leather making waste liquid at the middle of the hearth is facilitated; and the fluidized bed is applied to the bottom of the hearth, so that the bottom of the hearth is always soured by high-temperature bottom material which spreads in the fluidized bed and stays in the boiling state and no slagging is generated on the furnace wall.
Description
Technical field
The utility model relates to mechanical field, and particularly boiler specifically is a kind of boiler that fires waste leather-making liquid.
Background technology
Waste leather-making liquid is the harmful waste that the higher artificial leather enterprise of a kind of calorific value produces, fuel itself is also than thickness, can't directly in boiler, fully burn, but utilize certain pre-processing device, its atomizing back is cooperated boiler of the specific type of furnace generation steam that burnt, reach and to handle the purpose that refuse again can be profitable.The solid particle that produces behind the incineration of liquor in burner hearth is bonding mutually sometimes, fall above refractory surface can be bonded in, if untimely processing, can and refractory material react, cause the refractory material bulk to come off, influence the normal operation of boiler.Simultaneously want temperature moderate when the burner hearth internal combustion, too low fuel burns insufficient and is easy to stop working, and ignition temperature is too high to be easy to slagging scorification attached on the membrane wall.
Summary of the invention
The purpose of this utility model is to provide a kind of boiler that fires waste leather-making liquid, the boiler of described this combustion waste leather-making liquid will solve on the refractory material of its inwall that can bond when waste leather-making liquid burns in boiler in the prior art and cause the refractory material bulk to come off, and influences the technical problem of the normal operation of boiler.
The purpose of this utility model is achieved through the following technical solutions: comprise burner, upper drum, lower drum, be located at convection tube row, economizer and air preheater between the upper and lower drum, the burner hearth of burner is the full film type wall structure, be provided with fluid bed at burner hearth bottom, lower furnace portion adopts pyramidal structure, the vertical section that the middle and lower part of burner hearth is square, burner hearth bottom and middle and lower part madial wall lay the fire-resistant abrasion-proof cast bed of material, be provided with sparge pipe at the burner hearth middle part, sparge pipe is connected with burner hearth cavity, and sparge pipe is downward-sloping.
Evenly be distributed with 4 sparge pipes along the burner hearth circumference.
Convection tube row and economizer soot blower is installed.
Be provided with two dust legs at the lower drum place, below economizer and air preheater, respectively be provided with one and put grey structure.
The fire-resistant abrasion-proof cast thickness of feed layer of burner hearth sidewall increases gradually from lower furnace portion to top.
The utility model is compared with prior art, and its effect is actively with tangible.The utility model is provided with full film type wall in the burner hearth of fluidized-bed combustion boiler, be that whole inboard wall of burner hearth is equipped with membrane wall from top to bottom, the too high slagging scorification of temperature is attached on the membrane wall when preventing the waste leather-making liquid burning, be provided with downward-sloping sparge pipe at the burner hearth middle part, insert spray gun therein and can in burner hearth, spray remove from office waste liquid, being convenient to waste leather-making liquid fully burns at the middle part of burner hearth, simultaneously, in burner hearth bottom, burner hearth bottom is subjected to all the time being in the washing away of high-temperature bed material of fluidized state in the fluid bed and can form slagging scorification on the furnace wall with fluidized bed applications.The fire-resistant abrasion-proof of inboard wall of burner hearth waters material feeding and adopts the chromium that contains that is difficult for the sodium reaction to water material feeding, avoids waste leather-making liquid and water material feeding reacting, and influences the work of boiler.The material feeding thickness that waters that burner hearth sidewall lays is had any different in zones of different, thereby effectively controls fire box temperature, avoids this part to produce slagging scorification, guarantees waste liquid fully smooth combustion in burner hearth simultaneously.
Description of drawings
Fig. 1 is that master of the present utility model looks cutaway view.
Fig. 2 is the left view of Fig. 1.
The specific embodiment
The utility model is described in further detail by embodiment below in conjunction with accompanying drawing.
As depicted in figs. 1 and 2, in the present embodiment, the boiler of this combustion waste leather-making liquid comprises burner, upper drum 1, lower drum 2, be located at, convection tube row 3 between the lower drum, economizer 4 and air preheater 5, the burner hearth 6 of burner is the full film type wall structure, be that the whole sidewall of burner hearth is provided with the water-cooled membrane wall, be provided with fluid bed 7 in burner hearth 6 bottoms, lower furnace portion adopts pyramidal structure, particle after being convenient to burn falls, the vertical section that the middle and lower part of burner hearth is square, burner hearth bottom and middle and lower part madial wall lay the fire-resistant abrasion-proof cast bed of material 61, at the burner hearth middle part, evenly be distributed with 4 sparge pipes along the burner hearth circumference, sparge pipe 62 is connected with burner hearth cavity, and sparge pipe 62 is downward-sloping, insert spray gun at sparge pipe 62 during use and can in burner hearth, spray waste leather-making liquid, in the burner hearth internal combustion.Fire-resistant abrasion-proof waters material feeding and adopts the material feeding of watering that contains chromium, prevents the sodium-containing material in the waste leather-making liquid comburant and waters the material feeding reaction, destroys the cast bed of material.
The fire-resistant abrasion-proof cast thickness of feed layer of burner hearth sidewall increases gradually from lower furnace portion to top.Thereby effectively control fire box temperature, avoid this part to produce slagging scorification, guarantee waste liquid fully smooth combustion in burner hearth simultaneously.
Convection tube row and economizer soot blower 10 is installed.Be provided with two dust legs 8 at the lower drum place, below economizer and air preheater, respectively be provided with an ash-removing mouth 9, can solve the problem that heated surface at the end of boiler is easy to dust stratification.
