Abstract
The utility model relates to a fluid bed water and air cinder cooling device, which comprises a frame, a fluid bed chamber with wind inlet and wind outlet positioned on the frame, and a snake-shaped cooling water pipe with outside having cooling water medium inlet and outlet. The fluid bed chamber is also connected with a slag dropping pipe and a slag eliminating pipe. The bottom of the fluid bed is provided with a grid plate having net hole and nozzle button, and the net hole on the grid plate is communicated with the fluid bed chamber and the air inlet air chamber. The grid plate is provided with a fire-resistant and abrasion preventing layer. The circumference in the fluid bed chamber is provided with the seal protection plate and internal lining abrasion preventing layer. The high-temperature furnace slag directly fluidizes and exchanges heat with cold air during fluidising process to make the furnace slag temperature reduced, and synchronously the hot air produced by exchanging heat is exhausted through the air outlet for recovering and using to reach the effect of saving energy. The cooling of the furnace slag adopts dried disposal, which fully ensures the activity of the furnace slag and is benefited for the comprehensive utilization.
Description
Technical field:
The utility model relates to a kind of subsidiary engine equipment that is applied in the station boiler field, specifically a kind of fluidized bed type geomantic omen slag cooler.
Background technology:
The invention of self-fluidized type bed combustion technology and since station boiler field utilization, because its plurality of advantages and favorable environment protection energy, make this technology obtain large-scale promotion and application in thermoelectric field, and be subjected to paying attention to widely, because the development capacity of fluidized-bed combustion boiler main frame is in continuous increase, boiler capacity by the leading type of furnace of original 75t/h, develops into the leading type of furnace about present 220t/h and 410t/h, and from now on also in progressively increase.Along with the continuous increase of boiler host capacity, and supporting thereupon subsidiary engine equipment also must be caught up with, and only in this way could guarantee fully that unit and system stability move reliably.
Because the increase of fluidized-bed combustion boiler capacity, making it Coal-fired capacity hourly increases greatly, therefore the red-hot lime-ash of high temperature (about 900 ℃) that hour is discharged also rolls up simultaneously, so the discharging of Duo high temperature furnace slag is transported to normal safety in production and brings many problems and inconvenience, so requirement must be resolved.But how to handle the red-hot slag of above-mentioned a large amount of high temperature well? must solve following four problems: 1, make a large amount of high temperature furnace slags in the effective time, be cooled to be convenient to the temperature that upstream device is carried and transported, be generally below 150 ℃.2, will guarantee that in cooling procedure waste heat does not run off, recycling that can be a large amount of is to reach purpose of energy saving.3, the cooling of slag will adopt dry process fully to guarantee the activity of slag, is beneficial to ash comprehensive utilization and is worth.4, all geomantic omen cooling processing processes all need to finish in closed container (equipment), and will guarantee reliable and stablely continuously for a long time, can not influence the main frame operation.To satisfy security, the flexibility of carrying out production strictly in line with rules and regulations simultaneously with operation maintenance personnel adjustment operation.
Summary of the invention:
The purpose of this utility model just is based on a kind of novel fluidized bed formula geomantic omen slag cooler that solves above-mentioned four problems and provide.
The purpose of this utility model is to realize like this, it comprises a framework and places and have the fluid-bed chamber of air inlet and air outlet on this framework and place the snakelike cooling water pipe that tyre cooling water medium is gone into, exported in the fluid-bed chamber that it is characterized in that: fluid-bed chamber also is connected with slag dropping tube and scum pipe; The bottom of fluid-bed chamber is the air distribution plate that has mesh and blast cap, on this air distribution plate the mesh of being be connected with fluid-bed chamber and air inlet air compartment, air distribution plate is provided with fire-resistant scuff-resistant coating; Be provided with sealing backplate and liner scuff-resistant coating around in the fluid-bed chamber.Its operation principle is: after the slag of red-hot high temperature falls into horizontal fluidised bed chamber via slag dropping tube, move to slag-drip opening by bottom air inlet one's intention as revealed in what one says chamber through the pressure cool stream wind transmission fluidisation that air distribution plate and blast cap are blown into, direct and the cold wind fluidisation heat exchange in fluidisation of high temperature furnace slag this moment, slag temperature is reduced, finally discharge through scum pipe.Hot blast after this moment heat absorption through top the further heat exchange of snakelike cooling water pipe after air outlet is discharged final the recycling.The cooling water medium is entered after fluid-bed chamber and high temperature furnace slag and pressure hot blast carry out surface heat exchanging through snakelike cooling water pipe by the cooling water medium inlet, discharges through the cooling water media outlet and recycles.
Can find out that from the description of said structure and operation principle the utility model has solved four problems described in the background technology preferably.Moreover, in recovery waste heat, also can make boiler efficiency improve about two percentage points, and can realize effective automatic discharge control, make the burning of boiler more reasonable, more efficient with the boiler host computer system.Also be effective import substitute simultaneously, can save 2 to 3 times of import funds.
Description of drawings:
Fig. 1 is the utility model structural representation.
Fig. 2 is the vertical view of Fig. 1.
Fig. 3 is the left view of Fig. 1.
The specific embodiment:
By accompanying drawing as can be known, the utility model mainly comprises framework of being made by steel column, channel-section steel, angle steel welding 1 and fluid-bed chamber 19 and the air inlet 8 that is connected with fluid-bed chamber 19 and air outlet 7, slag dropping tube 4 and the scum pipe 5 that is made of air distribution plate 2, fire-resistant scuff-resistant coating 16, sealing backplate 14, liner scuff-resistant coating 13 and top cover 18, be provided with snakelike cooling water pipe 12 in fluid-bed chamber 19, the cooling water medium is gone into, is exported collection case 10,11 and places fluid-bed chamber outside and be connected with snakelike cooling water pipe 12.Have on the air distribution plate 2 mesh and with the corresponding blast cap 3 of mesh, on this air distribution plate the mesh of being be connected with fluid-bed chamber 19 and air inlet air compartment 17, fire-resistant scuff-resistant coating 16 places on the air distribution plate.Be sealing backplate 14 and liner scuff-resistant coating 13 around in the fluid-bed chamber.After the slag of red-hot high temperature falls in the horizontal fluidised bed chamber 19 via slag dropping tube 4, move to slag-drip opening 6 by bottom air inlet mouth 8 and air inlet air compartment 17 through the pressure cool stream wind transmission fluidisation that air distribution plate 2 and blast cap 3 are blown into, direct and the cold wind fluidisation heat exchange in fluidisation of high temperature furnace slag this moment, slag temperature is reduced, finally discharge through scum pipe 5.Hot blast after this moment heat absorption through top snakelike cooling water pipe 12 further heat exchange after air outlet 7 is discharged final recycling.The cooling water medium is entered after fluid-bed chamber and high temperature furnace slag and pressure hot blast carry out surface heat exchanging through snakelike cooling water pipe 12 by cooling water medium inlet collection case 10, discharges through cooling water media outlet collection case 11 and recycles.Sequence number 9 is fluid-bed chamber inspection maintenance aperture of door among the figure.
