Abstract
The utility model discloses a pipeline capable of distributing and adjusting coal powder and a coal powder distributing and adjusting device in the pipeline. The coal powder distributing and adjusting device in the pipeline comprises concentration blocks and two distributing and adjusting baffles, the concentration blocks are arranged on the inner wall faces of the two sides of an inlet header pipe, the distributing and adjusting baffles are arranged on branches of the header pipe and branch pipes, each distributing and adjusting baffle comprises a shaft and a baffle body, the shaft of each distributing and adjusting baffle penetrates through the outer wall of the header pipe and is fixed in a sealed mode, the baffle of each distributing and adjusting baffle is fixed to the corresponding shaft, and the pipeline capable of distributing and adjusting the coal powder comprises the header pipe, the two branch pipes and the coal powder distributing and adjusting device. According to the pipeline capable of distributing and adjusting the coal powder and the coal powder distributing and adjusting device in the pipeline, the amount of the powder entering the two branch pipes is balanced, and the problem that the pipes are blocked by other things cannot occur.
Description
Technical field
The utility model relates to the device of a kind of adjustment containing Solid concentration distribution in breeze airflow, relates in particular to the device of a kind of adjustment containing both sides coal dust pulverized coal particle concentration in breeze airflow pipeline.
Background technology
At present, coal-fired station's pulverized coal preparation system adopts positive pressure direct to blow system mostly, utilizes air pulverized coal conveying to burner hearth to burn by an airduct.Some airduct is designed to the structure of one-to-two, and a house steward is divided into two arms, and the coal dust in two arms enters boiler furnace through burner.
There are two kinds of situations at the bifurcated pipe place that is divided into arm house steward:
1) do not establish coal dust distributor; This situation very easily produces the raw deviation of coal dust volume production that enters two branched pipes, the total amount difference of the coal dust that two arms obtain from mother's pipe;
2) be provided with grid-like pulverized coal distributor: in the ideal case, this distributor can be realized the object of two arm coal dust amounts uniform distribution, but in using, often stopped up by the foreign material in coal dust and cause that the resistance of ducting increases, and makes two arm coal dusts and air capacity serious unbalance.
Utility model content
The purpose of this utility model is to provide and regulates the pipeline of coal dust and the interior coal dust of pipeline to distribute adjusting device a kind of distribution, makes to enter the powder amount equilibrium of two branched pipes, and does not have the possibility of being stopped up by foreign material.
The utility model adopts following technical proposals: in a kind of pipeline, coal dust distributes adjusting device, include concentrated block, two distribution controllable registers, described concentrated block is arranged on the internal face of entrance house steward both sides, described distribution controllable register is separately positioned on the crotch of house steward and two arms, wherein distribute controllable register to include axle and baffle plate, described axle is located on house steward's outer wall, and sealing is fixing, and described baffle plate is fixed on axle.
Described concentrated block is rhombus antiwear high manganese steel.
The invention also discloses a kind of pipeline that regulates coal dust that distributes, include house steward and two arms, concentrated block is arranged on the internal face of entrance house steward both sides, described distribution controllable register is separately positioned on the crotch of house steward and two arms, wherein distribute controllable register to include axle and baffle plate, described axle is located on house steward's outer wall, and sealing is fixing, and described baffle plate is fixed on axle.
Described house steward by circle Fang Jie and above the pulverized coal channel of circular cross-section is connected, two described arms pass through to justify Fang Jie and are connected with the pulverized coal channel of circular cross-section below.
Described concentrated block is rhombus antiwear high manganese steel.
The utility model channel interior is provided with concentrated block and distributes controllable register, after total contained pulverized coal particle of air in tube-coal powder two-phase flow impinges upon on concentrated block because the effect of inertia is to two lateral enrichments, distribute the angle of controllable register to adjust, thereby change the coal dust amount that enters two branched pipes.Can realize coal dust amount and air capacity distributed uniform in two arms by test adjustment, and can be because of the foreign material in coal dust blocking channel.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, the utility model discloses coal dust in a kind of pipeline and distribute adjusting device, include concentrated block 1, two and distribute controllable register, described concentrated block 1 is arranged on the internal face of entrance house steward 4 both sides, described distribution controllable register is separately positioned on the crotch of house steward 4 and arm 51,52, wherein distributes controllable register to include axle 21 and baffle plate 22, and described axle 21 is through house steward's 4 outer walls, can regulate, described baffle plate 22 is fixed on axle 21; Another distributes controllable register to include axle 31 and baffle plate 32, and structure and axle 21, baffle plate 22 are identical.Described concentrated block 1 is rhombus concentrated block, rhombus concentrated block, baffle plate and axle, and material is Q460 or other antiwear high manganese steels.
The invention also discloses a kind of pipeline that regulates coal dust that distributes, include house steward 4 and two arms 51,52, concentrated block 1 is arranged on the internal face of entrance house steward 4 both sides, described distribution controllable register is separately positioned on the crotch of house steward 4 and arm 51,52, wherein distribute controllable register to include axle 21 and baffle plate 22, described axle 21, through house steward's 4 outer walls, can regulate, and described baffle plate 22 is fixed on axle 21; Another distributes controllable register to include axle 31 and baffle plate 32, and structure and axle 21, baffle plate 22 are identical.Described concentrated block 1 is rhombus concentrated block, rhombus concentrated block, baffle plate and axle, and material is Q460 or other antiwear high manganese steels.Described house steward 4 by circle Fang Jie and above the pulverized coal channel of circular cross-section is connected, described two arms 51,52 are connected with the pulverized coal channel of circular cross-section below by circle Fang Jie, by welding or flange connection all can.
Described concentrated block 1 welds or bolt is connected on the internal face of rectangle entrance house steward both sides, runs through total tube passage.Between axle 21,31 and house steward's outer wall, use mechanical seal, guarantee containing breeze airflow not to outward leakage; The gap about 2mm is reserved with total inside pipe wall in baffle plate 22,32 two ends, is convenient to regulate.After the coal dust containing in breeze airflow in the middle of house steward 4 impinges upon on concentrated block because the effect of inertia is to two lateral enrichments, the angle of axle 21,31 controllable registers 22,32 that utilization exposes, axle can drive baffle plate to rotate, locked with nut after rotating, and changes the coal dust amount that enters two branched pipes.
