Description

The conveying equipment of petroleum coke powder
Technical field
The utility model relates to petroleum coke powder combustion auxiliary equipment, especially, relates to a kind of conveying equipment of petroleum coke powder.
Background technology
Under normal circumstances, the conveying of powder all adopts the form of Geldart-D particle.Namely by intermediate equipment venturi, air inlet is to venturi, and venturi forms negative pressure, drives powder to leave.This mode of movement does not have the environment of requirement for height to be reasonable a kind of mode of movement for flow accuracy.But under the higher environment of petroleum coke powder control accuracy, the Combustion System of such as kiln, common Geldart-D particle does not obviously reach effect, because common Geldart-D particle requires the air of large discharge, these air are brought kiln into and are formed nitride contaminated environment, and to amount of heat be taken away after discharge kiln, a large amount of cold air enters the rear combination affecting fuel and oxygen with fuel simultaneously, affects combustion efficiency.So pollute little when fuel combustion, and the feed mode before just requiring rifle when blowdown is few has just had higher requirement.
In the kiln application of reality, because environmental requirement is higher, all-oxygen combustion control system obtains applying comparatively widely.Because air reaches in the kiln of 1200 DEG C in temperature, the nitride that chemical reaction forms atmosphere pollution will occur, and a large amount of cold airs enters kiln with coke powder simultaneously, and dilute oxygen concentration, the burning of coke powder is insufficient, affects product quality.If drive petroleum coke powder with oxygen, unsafe factor is had to exist, once run into the danger that naked light has blast.But the price of petroleum coke powder is a lot of for natural gas and heavy oil relative moderate, if can control to minimum to the air capacity entering kiln, or a kind of well fuel.
Utility model content
The utility model object is the conveying equipment providing a kind of petroleum coke powder.
For achieving the above object, the utility model provides a kind of conveying equipment of petroleum coke powder, comprising: the venturi vertically arranged, and the top of described venturi is petroleum coke powder input port, and the bottom of described venturi connects gas powder hybrid chamber; In described venturi, be provided with the breather pipe of hollow, the top of described breather pipe is the shape of solid conical, and the bottom of described breather pipe is the shape of hollow cone, and the bottom of described hollow cone sets out air port, the corresponding described gas powder hybrid chamber of described air outlet; The side of described venturi is provided with connecting pipe, and admission line is connected with described breather pipe through described connecting pipe.
Further, the aperture of described air outlet is 2mm-15mm.
Further, the gas flow rate of described air outlet ejection is greater than velocity of sound.
Further, described admission line is provided with pressure versus flow detecting element.
Further, the body of described venturi bottom is provided with pressure detecting element.
Further, support fixture is provided with between described connecting pipe and described admission line.
Further, the top of described venturi, bottom and body are respectively arranged with flange.
The utility model has following beneficial effect:
The flow of the petroleum coke powder of the conveying equipment of this petroleum coke powder can accurately control, petroleum coke powder and combination with oxygen effective, can Thorough combustion, pollute little, petroleum coke powder drives security performance good without oxygen, can extensive use.
Accompanying drawing explanation
Below with reference to figure, the utility model is described in further detail.The accompanying drawing forming a application's part is used to provide further understanding of the present utility model, and schematic description and description of the present utility model, for explaining the utility model, is not formed improper restriction of the present utility model.In the accompanying drawings:
Fig. 1 is the structural representation of the conveying equipment preferred embodiment of the utility model petroleum coke powder.
Description of reference numerals:
1, venturi; 2, petroleum coke powder input port; 3, gas powder hybrid chamber; 4, breather pipe; 5, air outlet; 6, connecting pipe; 7, admission line; 8, fixture is supported; 9, flange.
Detailed description of the invention
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail.
Refer to Fig. 1, preferred embodiment of the present utility model provides a kind of conveying equipment of petroleum coke powder, comprising: the venturi 1 vertically arranged, and the top of described venturi 1 is petroleum coke powder input port 2, and the bottom of described venturi 1 connects gas powder hybrid chamber 3; The breather pipe 4 of hollow is provided with in described venturi 1, the top of described breather pipe 4 is the shape of solid conical, the bottom of described breather pipe 4 is the shape of hollow cone, and the bottom of described hollow cone sets out air port 5, the corresponding described gas powder hybrid chamber 3 of described air outlet 5; The side of described venturi 1 is provided with connecting pipe 6, and admission line 7 is connected with described breather pipe 4 through described connecting pipe 6.
When the conveying equipment of this petroleum coke powder works, pass into gases at high pressure in breather pipe 4 through admission line 7, gas ejects from air outlet 5, makes to form negative pressure in venturi 1; Petroleum coke powder enters in venturi 1 from petroleum coke powder input port 2, and under gravity, petroleum coke powder drops to the bottom of venturi 1, and under the drive of air-flow, enter into gas powder hybrid chamber 3 Homogeneous phase mixing, and then enters kiln combustion.
The size of the flow of the conveying equipment conveying petroleum coke powder of this petroleum coke powder, see the compressed-air actuated flow at air outlet place, and the negative pressure that the high then venturi bottom of flow is formed is high, drives the ability of petroleum coke powder stronger, otherwise then contrary.According to related experiment, if access compressed air pressure is 0.4Mpa, flow is 20Nm3/h, and petroleum coke powder flow is 60Kg/h; And petroleum coke powder flow is with constant flow blanking.When opening compressed air, its flow is made to be 20Nm3/h.According to Bernoulli equation, due to compressed air from lower end conical pipe blowout, make Venturi tube top formed negative pressure, thus drive air enter venturi lower channel, and send " z z z " sound, illustrate that now compressed air is stablized.Open petroleum coke powder, make its flow be 60Nm3/h, so petroleum coke powder is just inhaled into venturi premix place by Venturi tube, then enter into pipeline, and then burn to kiln.
Preferably, in order to reduce air capacity to greatest extent and improve conveying gas kinetic energy, the gas flow rate that air outlet 5 sprays is greater than velocity of sound, and the aperture of air outlet 5 is 2mm-15mm.
Preferably, for ease of detecting pressure and the flow of the Compressed Gas that admission line 7 passes into, described admission line 7 is provided with pressure versus flow detecting element (not shown).When starting shooting operation, first can lead to compressed air, and checking pressure and flow, and then determining the flow of petroleum coke powder again.
Preferably, for convenience of the back pressure detecting venturi, the convenient smooth degree at venturi detecting petroleum coke powder, the body of described venturi 1 bottom is provided with pressure detecting element.
Preferably, for making firmly to be connected between connecting pipe with admission line, being provided with between described connecting pipe 6 and described admission line 7 and supporting fixture 8.
Preferably, for convenience of the connection of venturi and access conduit, the top of described venturi 1, bottom and body are respectively arranged with flange 9.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model; For a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
