The pneumatic coal ash collecting system comprises a gas supply system (8), a gas storage tank (9) connected with the gas supply system, a dry ash fluidization tank (7) and an ash storage silo (4) and is characterized in that the lower end of the dry ash fluidization tank (7) is connected with a branch fluidization pipe (11) through a pipeline, the upper end of the dry ash fluidization tank (7) is provided with a boiler coal ash inlet (1), the upper part of the dry coal ash fluidization tank is provided with a fluidization dry coal ash output hole, the dry coal ash fluidization tank is connected with a branch coal ash conveying pipe (12) through fluidization dry coal ash output pipelines (2), and an anti-blocking valve (14) is arranged between a place where the first fluidization dry coal ash output pipeline (2) on the branch dry coal ash conveying pipe is jointed with the branch dry coal ash conveying pipes (12) and a gas conveying branch pipe (10). The pneumatic coal ash collecting system can be used for collecting coal ash from different places in a closed environment, and hardly causes environmental pollution.
Description
Technical field
The invention belongs to boiler smoke treatment facility technical field, be specifically related to fly ash Pneumatic dust collecting system.
Background technology
Fly ash is one of larger industrial solid waste of the current discharge capacity of China, and along with the development of power industry, the fly ash quantity discharged of coal-burning power plant increases year by year.A large amount of fly ash does not add processing, will produce airborne dust, atmosphere pollution; The main source of fly ash is thermal power plant and the concentrated supply of heating in the city boiler take coal dust as fuel, wherein is wet ash discharge more than 90%, and is active low than dry ash, and water wasting expense electricity, and contaminated environment also is unfavorable for comprehensive application.For protection of the environment better and be conducive to the comprehensive application of fly ash, dry ash collection has become the development tendency that fly ash is from now on collected.
Summary of the invention
The objective of the invention is to solve the problem that prior art exists, a kind of fly ash Pneumatic dust collecting system of many boilers is provided.
The present invention solves the problems of the technologies described above the technical scheme of taking to be:
Fly ash Pneumatic dust collecting system comprises gas supply system, the storage tank that is connected with gas supply system, dry ash streaming tank and stores up grey storehouse; It is characterized in that: the gas transmission main of being drawn by storage tank is divided into some gas transmission arms, and every gas transmission arm is divided into branch line ash pipeline and branch line fluidisation pipe, and dry ash streaming tank lower end is connected with branch line fluidisation pipe by pipeline, and its upper end is provided with the boiler fly ash entrance; Dry ash streaming tank top arranges fluidisation dry ash delivery port, and is connected with the branch line ash pipeline by fluidisation dry ash delivery piping; The branch line ash pipeline passes into the grey storehouse of storage; Between the gas transmission arm, anti-blocking valve is set at first fluidisation dry ash delivery piping on the branch line ash pipeline and access place of branch line ash pipeline; At storage Hui Ku top dust exhaustor is set.
The present invention compared with prior art has following beneficial effect:
Because the present invention adopts the closed conduit ash-transmission system, avoids producing airborne dust, atmosphere pollution is collected fly ash by pneumatic pipe, be conducive to the comprehensive application of fly ash.
