Along with industrial expansion, conveyer belt is increasingly being applied to the continuous conveying of short distance material, in steam power plant, by
Being continual in boiler to coal-fired utilization, the slag of after-flame also can discharge boiler continuously, and therefore conveyer belt is in warm
Conveying and the output of slag of fire coal it is mainly used in power plant.
During utilizing conveyer belt that slag is exported continuously, due to slag-drip opening and the conveyer belt table of the slag-draining device of boiler
There is certain difference in height in face, and slag is to fall on conveyer belt surface with certain speed impacts, evokes substantial amounts of airborne dust, it addition,
During conveyer belt transmits, situation about jolting occurs the most unavoidably, substantial amounts of airborne dust can be produced equally, raising of constant generation
On the one hand the healthy of field personnel can be brought serious threat by dirt, on the other hand can affect to a certain extent near
The normal operation of equipment, can cause equipment fault what is more or forever scrap.
The airborne dust produced during slag transmits can be effectively removed accordingly, it would be desirable to a kind of.
Utility model content:
In order to solve the problems referred to above, this utility model provides a kind of steam power plant slag and transmits airborne dust removal device.
Described steam power plant slag transmits airborne dust removal device, including negative pressure dust removing equipment and spray for dust suppression equipment, negative pressure dust removing equipment
The negative tube being connected with negative pressure power source including a upper end, negative tube lower end is connected to the slag-draining device of boiler by ring for fixing,
The lower end outlet of boiler slag removal device is slag-drip opening, is conveyer belt starting point immediately below slag-drip opening, and the negative tube mouth of pipe is positioned at slag and drops
At 45 degree of oblique upper 20cm-25cm of point；Spray for dust suppression equipment includes tap water pipe line and shower nozzle, and shower nozzle is connected by ring for fixing
On negative tube, shower nozzle is positioned at the negative tube mouth of pipe along at slag direction of motion 20cm-30cm.
In a kind of embodiment of the present utility model, described negative tube is the circular pipeline of diameter 15cm-20cm, described negative pressure
Pipe is stainless steel tube or the PVC plastic pipe of thickness of pipe wall 3mm-5mm of thickness of pipe wall 1mm-2mm.
In a kind of embodiment of the present utility model, inside described negative tube, scribble politef anti-stick coating, can be the most anti-
Only dust sticks in inside negative tube.
In a kind of embodiment of the present utility model, described negative pressure power source is negative pressure system or the boiler flue of boiler induced-draft fan.
In a kind of embodiment of the present utility model, described tap water pipe line is nylon hose or the silica gel hose of internal diameter 20mm.
In a kind of embodiment of the present utility model, described shower nozzle is common atomizer.
The beneficial effects of the utility model:
(1) steam power plant described in the utility model slag transmits airborne dust removal device operationally, due to the existence of negative tube suction,
Most airborne dust negative suction pipe can be eventually entered into boiler induced-draft fan or flue, effectively remove slag-drip opening generation and raise in a large number
Dirt, the slag on conveyer belt is after shower nozzle is sprayed, and humidity increases, and can effectively reduce during transmission due to hundred generations of jolting
Airborne dust, safeguard work personnel health and the normal operation of neighbouring equipment；
(2) negative pressure system that negative pressure power source is boiler induced-draft fan used by this utility model or boiler flue, it is not necessary to use specially
Door power, the energy is saved in design cleverly；
(3) scribble politef anti-stick coating inside negative tube, effectively prevent airborne dust accumulation inside negative tube, it is to avoid be negative
In use there is stopping state in pressure pipe；
Accompanying drawing illustrates:
Fig. 1: steam power plant of the present utility model slag transmits airborne dust removal device structural representation；Wherein, 1 negative tube, 2 negative pressure are moved
Power source, 3 boiler slag removal devices, 4 slag-drip openings, 5 conveyer belts, 6 ring for fixings, 7 shower nozzles, 8 tap water pipe lines.
Detailed description of the invention:
Below in conjunction with the drawings and specific embodiments, this utility model is further elaborated.
Embodiment 1
Steam power plant's slag as shown in Figure 1 transmits airborne dust removal device, including negative pressure dust removing equipment and spray for dust suppression equipment, negative pressure
Cleaner includes the negative tube 1 that a upper end is connected with negative pressure power source 2, and negative tube 1 lower end is connected to by ring for fixing 6
The slag-draining device 3 of boiler, the lower end outlet of boiler slag removal device 3 is slag-drip opening 4, is conveyer belt 5 starting point immediately below slag-drip opening 4,
Negative tube 1 mouth of pipe is positioned at 45 degree of oblique upper 20cm of slag drop point；Spray for dust suppression equipment includes tap water pipe line 8 and shower nozzle
