Abstract
The utility model relates to the technical field of pulverized coal filters, in particular to an accumulated coal recycling device of a pulverized coal filter. The accumulated coal recycling device comprises a pulverized coal filter and a pulverized coal collector which is connected with the pulverized coal filter, wherein an air supplementing valve is arranged on a pipeline of the pulverized coal collector connected with the pulverized coal filter; the air supplementing valve is connected with a fan; and a blowdown valve is arranged at the bottom of the pulverized coal filter. According to the utility model, by using a blast furnace coal spray pipeline recycling device with the structure, pulverized coal accumulated in the filter returns into a pulverizing device under the effect of the air supplementing valve, so that the pulverized coal is recycled, environment pollution is avoided, resources are saved and environment friendly, energy-saving and economical purposes are achieved. The accumulated coal recycling device of the pulverized coal filter, provided by the utility model, has the advantages of small investment, high benefits and simplicity in operation; the labour intensity can be effectively reduced and the phenomenon that a gun is blocked by the spray coal is reduced.
Description
Technical field
The utility model relates to the pulverized coal injection equipment technical field, relates in particular to the long-pending coal recycling device of a kind of coal dust strainer.
Background technology
Pulverized coal injection must be installed the coal dust strainer on convey coal pipe, in order to the impurity that carries in the bug dusting, it is smooth and easy, stable to guarantee that coal dust flows, and after strainer work for some time, impurity can increase gradually, needs cleaning.Former technology is that remaining coal dust and waste material are abandoned simultaneously, perhaps it is caused in the waterways through pipeline, so not only wastes resource but also contaminate environment; Even take the humidification discharging; Also just suppress airborne dust, can not take into account not only environmental protection but also aim of saving, cause the secondary pollution of water quality simultaneously.If carelessness is arranged in the strainer scale removal process slightly, impurity can be cut lock in the filter screen back, causes stifled rifle even plugging road, and it is very necessary therefore designing a kind of device that the coal dust that accumulates in the strainer is reclaimed and handles.
The utility model content
In order to solve the problems of the technologies described above, the utility model provides a kind of and can the coal dust in the strainer be reclaimed, and solves the pulverized coal injection line strainer coal dust retrieving arrangement of stifled rifle, environmental pollution and energy dissipation problem of coal powder injection from the source.
The coal dust strainer of the utility model amasss coal recycling device, and it comprises coal dust strainer and the coal collector that is connected with the coal dust strainer, on the pipeline of the coal collector that is connected with the coal dust strainer, is provided with the benefit air-valve, mends air-valve and is connected with blower fan.
The coal dust strainer of the utility model amasss coal recycling device, and the bottom of said coal dust strainer is provided with wash water valve.
Compared with prior art; The beneficial effect of the utility model is: the utility model adopts the pulverized coal injection pipeline retrieving arrangement of this structure; The coal dust that accumulates in the strainer turns back in the fuel pulverizing plant through the effect of mending air-valve, has realized the utilization again of coal dust, has avoided the pollution to environment; Also practice thrift resource, reached environmental protection, energy-conservation, the purpose of practicing thrift.The utlity model has little, the high efficiency of investment, simple to operate, can reduce labour intensity effectively, reduce the advantage of the stifled rifle phenomenon of coal powder injection.
Description of drawings
Fig. 1 is the structure iron of the long-pending coal recycling device of coal dust strainer among the utility model embodiment.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the embodiment of the utility model is described in further detail.Following examples are used to explain the utility model, but are not used for limiting the scope of the utility model.
As shown in Figure 1; The coal dust strainer of present embodiment amasss coal recycling device; It comprises coal dust strainer 1 and the coal collector 2 that is connected with coal dust strainer 1, on the pipeline of the coal collector 2 that is connected with coal dust strainer 1, is provided with to mend air-valve 3, mends air-valve 3 and is connected with blower fan 4.
The coal dust strainer of the utility model amasss coal recycling device, and the bottom of said coal dust strainer 1 is provided with wash water valve 5.
The utility model adopts the pulverized coal injection pipeline retrieving arrangement of this structure; The coal dust that accumulates in the strainer turns back in the fuel pulverizing plant through the effect of mending air-valve, has realized the utilization again of coal dust, has avoided the pollution to environment; Also practice thrift resource, reached environmental protection, energy-conservation, the purpose of practicing thrift.The utlity model has little, the high efficiency of investment, simple to operate, can reduce labour intensity effectively, reduce the advantage of the stifled rifle phenomenon of coal powder injection.
The above only is the preferred implementation of the utility model; Should be understood that; For those skilled in the art; Under the prerequisite that does not break away from the utility model know-why, can also make some improvement and modification, these improvement and modification also should be regarded as the protection domain of the utility model.
