The pneumatic coal ash collecting system comprises an air supply system (8), an air storage tank (9) which is connected with the air supply system (8), dry ash fluidization tanks (7) and an ash storage room (4), and is characterized in that the lower ends of the dry ash fluidization tanks (7) are connected with branch fluidization pipes (11) through pipelines; boiler coal ash inlets (1) are formed at the upper ends of the dry ash fluidization tanks (7); the upper parts of the dry ash fluidization tanks are provided with fluidized dry ash output holes, and are connected with branch ash conveying pipes (12) through fluidized dry ash output pipelines (2); and anti-blocking valves (14) are arranged between positions where the first fluidized dry ash output pipeline (2) and the branch ash conveying pipes are connected, and the air conveying branch pipes (10) on the branch ash conveying pipes (12). The system can be used for collecting coal ash at different places in an enclosed environment, and has low environmental pollution.
Description
Technical field
The utility model belongs to boiler smoke treatment facility technical field, is 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 purpose of this utility model is to solve the problem that prior art exists, and a kind of fly ash Pneumatic dust collecting system of many boilers is provided.
The utility model is to solve 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 and stores up grey storehouse; 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 utility model adopts the closed conduit ash-transmission system, avoid producing airborne dust, atmosphere pollution is collected fly ash by pneumatic pipe, be conducive to the comprehensive application of fly ash.
