Abstract
The utility model discloses a kind of economizer ash-transmission system, including some economizer storehouses pump, the bottom of economizer storehouse pump offers opening, and two adjacent economizer storehouse pumps are one group, the opening of same group of economizer storehouse pump is connected by the first pipeline, and the two ends of the first pipeline are equipped with gate valve;Same group of economizer storehouse pump is connected with the first pipeline of one group of adjacent economizer storehouse pump by the second pipeline, and the 3rd pipeline one end is connected with the second pipeline, and the other end is obliquely installed towards steel belt machine, the first pipeline, the second pipeline and the 3rd pipeline.The utility model is used from grey pattern is fallen, the problems such as can reducing plugging, the abrasion of economizer ash-transmission system.Because the first pipeline, the second pipeline and the 3rd pipeline are obliquely installed, so will not occur plugging phenomenon, ash path angle change in moving process is smaller, so the abrasion of each pipeline can be reduced, so as to improve overall stability.
Description
Technical field
The utility model is related to Coal Transportation System, more particularly to a kind of economizer ash-transmission system.
Background technology
Conventional power plant's economizer ash-transmission system form is safeguarded as shown in figure 1, the problem of existing in the process of running is more
Amount is big, and fault rate is high, has a strong impact on safe operation and the bringing normally into operation of economizer ash-transmission system.1st, ash-transmission system plugging is serious.
Threeway, the frequent plugging of straight tube, blocking are all caused because of bulk clinker, the maximum clinker size such as palm.2nd, economizer is defeated
Grey pipeline, elbow serious wear.The defeated grey elbow newly changed, which is only run 37 days, to be worn through, and pipe skin thick soldering 8mm also can only be hard
Hold 10 days or so, elbow is at high-altitude and no inspection platform, has a strong impact on defect elimination speed, and there is also larger peace during work
Full hidden danger.3rd, storehouse pump vaporizer threeway serious wear.In general, pump region flow velocity in storehouse is relatively low, and wear extent should be little, but
It is that from the point of view of running situation, the defeated grey total system of economizer all has serious abrasion.4th, the defeated grey air consumption of economizer is big.Because saving coal
Device contains a large amount of clinkers, causes defeated ash difficult, can only be conveyed using single storehouse pump and to increase air inflow.So open 4 skies
Press system pressure ability 0.5Kpa, has a strong impact on the safe operation of whole ash-transmission system.5th, maintenance workload is big.The defeated ash of economizer
Pipeline is in high-altitude mostly, and maintenance workload is big, dangerous high.

The purpose of this utility model is there is provided a kind of economizer ash-transmission system, using grey pattern is fallen certainly, by itself weight
Power falls, the problems such as can reducing plugging, the abrasion of economizer ash-transmission system.
In order to solve the above technical problems, the utility model is adopted the following technical scheme that:
A kind of economizer ash-transmission system, including some economizer storehouses pump, the bottom of economizer storehouse pump offer opening, adjacent
Two economizer storehouse pumps be one group, the opening of same group of economizer storehouse pump is connected by the first pipeline, the two of the first pipeline
End is equipped with gate valve;Same group of economizer storehouse pump is connected with the first pipeline of one group of adjacent economizer storehouse pump by the second pipeline
Logical, the 3rd pipeline one end is connected with the second pipeline, and the other end is towards steel belt machine, and the first pipeline, the second pipeline and the 3rd pipeline are equal
It is obliquely installed.The system is used from falling grey mode, is fallen by self gravitation, thus will not plugging, one group of economizer storehouse pump leads
The ash gone out is collected by the first pipeline, and ash derived from two groups of economizer storehouse pumps is collected by the second pipeline, four groups of economizer storehouse pumps
Derived ash is collected by the 3rd pipeline, because the first pipeline, the second pipeline and the 3rd pipeline are obliquely installed, so will not send out
Raw plugging phenomenon, ash path angle change in moving process is smaller, so the abrasion of each pipeline can be reduced, so as to improve whole
The stability of body.
As one of which embodiment, some economizer storehouses pump is set into two rows, two row's economizer storehouse pumps pair
Claim arrangement, the first pipeline of four groups of economizer storehouse pumps of same second pipeline connection.
In a kind of foregoing economizer ash-transmission system, the first pipeline is incubated by 50 millimeters of thick rock wool, thick rock wool
Coated outside by 0.5 millimeter of color steel, prevent from scalding risk because high temperature triggers.
In order to further improve the heat insulation effect of each pipeline, the outer wall of the first pipeline, the second pipeline and the 3rd pipeline is applied
It is covered with high temperature resistant aluminium paint.
In a kind of foregoing economizer ash-transmission system, the downstream of gate valve is provided with expansion joint, the axle of expansion joint on the first pipeline
It is ± 100 millimeters to compensation rate, by setting expansion joint on the first pipeline, compacter, the peace that can coordinate a position
Dress is more firm, it is to avoid leakage.
In a kind of foregoing economizer ash-transmission system, the second pipeline, which is provided with peep hole and held, hits anvil, is beaten during to block
Open peep hole and tap dredging pipeline.
In a kind of foregoing economizer ash-transmission system, the first pipeline and the second pipeline are the seamless steel that external diameter is 219 millimeters
Pipe, the 3rd pipeline is to prevent longtime running inner wall abrasion selection composite ceramic tube.
Compared with prior art, the utility model is used from falling grey pattern, can reduce economizer ash-transmission system plugging,
The problems such as abrasion.Because the first pipeline, the second pipeline and the 3rd pipeline are obliquely installed, so will not occur plugging phenomenon, ash
Path angle change is smaller in moving process, so the abrasion of each pipeline can be reduced, so as to improve overall stability.
