Description
Technical field
The utility model belongs to coal dust conveying technology field, relates to a kind of pulverized coal conveying device, for gasification unit coal dust positive delivery.
Background technology
In gasification unit coal dust positive delivery field, coal dust is needed to enter high pressure coal dust conveying pot by middle coal dust conveying pot feed opening, then high pressure coal dust conveying pot is by being arranged on the high pressure gas input port input high pressure gas of bottom, the powder fluidized fallen in high pressure coal dust conveying pot is blown in the coal dust transfer line of high pressure coal dust conveying pot internal upper part, and then realizes gasification unit coal dust positive delivery.But the coal dust transfer line in high pressure coal dust conveying pot is the top be fixed on by support in high pressure coal dust conveying pot, the support being used as to support is easy to come off all can affect the conveying of coal dust with pipeline flexural deformation, thus affects the stability of coal dust load transfer device.
Summary of the invention
The purpose of this utility model is to overcome weak point of the prior art, a kind of dense phase pulverized coal middle and lower part feedway of research and development, for gasification unit coal dust positive delivery, have employed the coal dust diffuser of this structure, while Condensed transportation can be ensured, also ensure the stability of coal dust conveying.
In order to realize the purpose of this utility model, following for employing technical scheme is achieved by we:
A kind of dense phase pulverized coal middle and lower part feedway, comprise middle coal dust conveying pot, high pressure coal dust conveying pot, middle coal dust conveying pot is connected by the inlet point of valve group with high pressure coal dust conveying pot top, the bottom of high pressure coal dust conveying pot is provided with high pressure gas input media, it is characterized in that: between the bottom of described high pressure coal dust conveying pot and high pressure gas input media, be provided with fluidized plate, U-shaped coal dust transfer line is provided with in high pressure coal dust conveying pot, the mouth of coal dust transfer line extends to outside high pressure coal dust conveying pot through the tank skin of high pressure coal dust conveying pot, the port of coal dust transfer line mouth is connected with the coal dust input port of gasification furnace.
Further, described U-shaped coal dust transfer line is made up of coal dust delivery pipe and coal collector, and the port of coal dust delivery pipe input end is provided with coal collector.
Further, described U-shaped coal dust transfer line is arranged at the top of fluidized plate.
Further, the coal dust delivery pipe of described U-shaped coal dust transfer line is fixed on the tank skin in the middle part of high pressure coal dust conveying pot.
Further, described coal dust delivery pipe has two.
Further, described coal collector has two.
Beneficial effect
A kind of dense phase pulverized coal middle and lower part feedway, comprise middle coal dust conveying pot, high pressure coal dust conveying pot, wherein there is fluidized plate bottom high pressure coal dust conveying pot, by winding-up high pressure gas, realize coal dust and be in fluidisation state, arrange two coal collectors on fluidized plate top, the coal dust of fluidisation passes through coal collector, enter coal dust pipeline, adopt two, middle and lower part coal dust transfer line to export, thus avoid the situation of medium influence coal dust conveying in equipment to greatest extent.
