Technical field
The utility model is related to the technical fields of large coal-fired power plant pulverized-coal fired boiler, refer in particular to a kind of coal powder distribation dress
It puts.
Background technology
The Combustion System of pulverized-coal fired boiler and optimization are to realize the important technology approach of energy saving for power plants emission reduction, for big moulded coal
Powder boiler, whether uniform and air distribution is reasonable for the distribution of Pulverized Coal in operation, will directly influence the warp of unit operation
Ji property, safety and Environmental Protection Level.
Existing coal powder distribation device includes pulverized coal distributor and the hose being connected with the pulverized coal distributor, coal dust pass through
Hose is delivered in the pulverized coal distributor, wherein the pulverized coal distributor includes distributor chamber, the distributor chamber and the hose
Be connected, since the volume of the distributor chamber is larger, in order to ensure the efficiency of lime calcining, it is therefore desirable to hose quantity it is more, lead
The hose is caused to need bending that could be connected with the distributor chamber, coal dust from the top of the hose into bottom end transmission process,
Since the bottom end of the hose is directly connected with the distributor chamber, coal dust is during gravity for transport, in the hose bottom
Coal dust can be extruded, the hose is caused to occur to block and rupture event in bending part, not only causes coal powder distribation uneven, and
And production technology is seriously affected.
Utility model content
For this purpose, the technical problem to be solved by the utility model is to overcome hose described in the prior art easy in bending part
Occur to block and one kind is provided the problem of rupture and the hose is avoided to occur to block or rupture and can guarantee coal powder distribation
Uniform coal powder distribation device.
In order to solve the above technical problems, a kind of coal powder distribation device of the utility model, including pulverized coal distributor and with
The many flexible pipes that the pulverized coal distributor is connected, the pulverized coal distributor include distributor chamber and below the distributor chambers
Powder inlet, the hose are connected with the distributor chamber, and the powder inlet is connected with breeze blowing storehouse, on the hose with it is described
The bending part of distributor chamber connection is equipped with microwave remote sensor, and the microwave remote sensor is connected with controller, the controller and setting
Valve connection on the hose.
In one embodiment of the utility model, one end connection spray gun of the hose, the other end is passed with the microwave
Sensor is connected.
In one embodiment of the utility model, ball valve is equipped between the microwave remote sensor and the distributor chamber.
In one embodiment of the utility model, the distance of the microwave remote sensor to the distributor chamber is 600mm-
800mm。
In one embodiment of the utility model, the distance of the microwave remote sensor to the distributor chamber is 700mm.
The above-mentioned technical proposal of the utility model has the following advantages compared with prior art：
Coal powder distribation device described in the utility model, the bending part being connect with the distributor chamber on the hose are equipped with micro-
Wave sensor, the microwave remote sensor are connected with controller, not only avoid the bending of the hose, and overhaul convenient, appearance
During blocking, the microwave remote sensor can automatic belling, so as to save query time, also maintenance time is made to shorten.
Description of the drawings
In order to which the content for making the utility model is more likely to be clearly understood, below according to the specific implementation of the utility model
Example and with reference to attached drawing, is described in further detail the utility model, wherein
Fig. 1 is the schematic diagram of the utility model coal powder distribation device.
Specific embodiment
As shown in Figure 1, the present embodiment provides a kind of coal powder distribation device, divide including pulverized coal distributor and with the coal dust
The many flexible pipes 11 that orchestration is connected, the pulverized coal distributor include distributor chamber 21 and positioned at 21 lower section of the distributor chamber into powder
Mouth 22, the hose 11 is connected with the distributor chamber 21, and the powder inlet 22 is connected with breeze blowing storehouse, on the hose 11
The bending part being connect with the distributor chamber 21 is equipped with microwave remote sensor 30, and the microwave remote sensor 30 is connected with controller, described
Controller is connect with the valve being arranged on the hose 11.
Coal powder distribation device described in the present embodiment, more to be connected including pulverized coal distributor and with the pulverized coal distributor
Hose 11, the pulverized coal distributor include distributor chamber 21 and the powder inlet 22 positioned at 21 lower section of distributor chamber, the hose
11 are connected with the distributor chamber 21, and coal dust is transmitted in the distributor chamber 21 by the hose, the powder inlet 22 with
Breeze blowing storehouse is connected, by 22 pulverized coal conveying of powder inlet, the bending that is connect on the hose 11 with the distributor chamber 21
Place is equipped with microwave remote sensor 30, and the signals such as coal dust flow velocity, the microwave remote sensor can be detected by the microwave remote sensor 30
30 are connected with controller, and the signal of detection is delivered in the controller, and the controller is with being arranged on the hose 11
Valve connection, the controller adjusts the transmission quantity of coal dust in the hose by the aperture of valve in real time, so as to ensure coal
Powder is evenly distributed, and lime calcining is more efficient, and the utility model is avoided due to employing microwave remote sensor 30 in bending part
The bending of the hose, and overhaul convenient, when blocking, the microwave remote sensor 30 understands automatic belling, so as to save
Query time also makes maintenance time shorten.
