Abstract
The utility model discloses a high temperature furnace flue pipe. The inner wall of a stainless steel tube (1) is fixed and connected with several ceramic chips (2). The ceramic chip (2) is provided with a centre hole (3). The centre hole (3) is provided with a fixed sheet (4) inside which is fixed with the stainless steel tube (1). The centre hole (3) is movably connected with a ceramic bulkhead (5). The utility model has the good abradability, heat-resistance and decay-resistance as well as the certain heat-insulating property. The high temperature furnace flue pipe with such a structure can extend the service life.
Description
Affiliated technical field
The utility model belongs to a kind of conveyance conduit of high-temperature material, is meant a kind of conveyance conduit of high temperature furnace cigarette especially.
Background technology
At present, along with the exploitation of lignite resource, the power plant of burning brown coal sets up in succession.Because brown coal moisture is big, be difficult for drying, again because of its fugitive constituent height, coal dust explodes very easily naturally, and its pulverized coal preparation system should not adopt warehouse style, but adopts the electric fan mill directly to blow system.The drying medium of this system generally has " high temperature furnace cigarette+hot blast, high temperature furnace cigarette+low-temperature furnace smoke+hot blast, high temperature furnace cigarette+leak informaton+cold wind " three kinds of modes.As the high temperature boiler flue gas tube road of carrying the drier passage, be the important component part in this pulverized-coal fired boiler pulverized coal preparation system.High temperature furnace cigarette temperature is very high, and highest point can reach 1000 ℃.Existing high temperature boiler flue gas tube road adopts ordinary steel, steel alloy casting to form.It is high temperature resistant, anti-wear performance is poor, and long-time running very easily causes fracture, the breakage of pipeline, has directly influenced the safety of unit, causes stopping production when serious, loses very big.
Summary of the invention
The purpose of the utility model is to overcome the above-mentioned deficiency of prior art, and a kind of improved high temperature boiler flue gas tube road is provided, and it is high temperature resistant, anti-wear performance good, long service life.
For reaching above-mentioned purpose, the utility model is taked following technical scheme: the utility model is at the inwall of stainless steel body some potsherds that have been fixedly connected, potsherd is provided with centre bore, has stator and stainless steel tube sports association to connect in the centre bore, the movable ceramic plug that connects on the centre bore.
The utility model is taked technique scheme, have following beneficial effect: the utility model is because at the inwall of stainless steel body some potsherds that have been fixedly connected, potsherd has good wear-resisting, heat-resisting, decay resistance, and certain heat-proof quality is arranged.Centre bore is provided with plug, can make complete, the sealing of whole ceramic inner surface.Take the high temperature boiler flue gas tube road of this kind structure to improve service life greatly.
Description of drawings
Below in conjunction with drawings and Examples the utility model is elaborated:
Fig. 1 is the utility model structure diagram.
The specific embodiment
By shown in Figure 1: the utility model comprises: stainless steel body 1, potsherd 2, centre bore 3, stator 4, ceramic plug 5, the inwall of stainless steel body 1 some potsherds 2 that have been fixedly connected, potsherd 2 is provided with centre bore 3, there is stator 4 to be welded on the inwall of stainless steel body 1 in the centre bore 3, the movable ceramic plug 5 that connects on the centre bore 3.Pottery plug 5 adopts thread connection with centre bore 3.Stainless steel body 1 of the present utility model adopts the 1Cr25Ni20Si2 material, and potsherd 2 adopts the alundum (Al pottery.
Claims (1)
1. high temperature boiler flue gas tube road, it is characterized in that: at the inwall of stainless steel body (1) the some potsherds (2) that have been fixedly connected, potsherd (2) is provided with centre bore (3), have stator (4) to connect with stainless steel body (1) in the centre bore (3), centre bore (3) is gone up the movable ceramic plug (5) that connects.
