Description

A kind of flue gas initial filter device for coal-burning boiler
Technical field
The present invention relates to heat power plant boiler apparatus field, particularly relate to a kind of flue gas initial filter device for coal-burning boiler.
Background technology
In recent years, people are increasing to healthy concern, and air quality becomes the focus that people pay close attention to, and PM2.5 is as the important indicator weighing air quality, increasingly receives the concern of people especially.
In thermal power plant, or in industry processes and in people's daily life, all can use various boiler, these boiler oils can release large quantity of exhaust gas in combustion, it is directly discharged in environment if these waste gas are unprocessed, causes very big harm can to the environment of the live and work of people.
Existing waste gas treatment equipment is generally boiler exterior equipment, it is connected to boiler exterior to use, and the structure of this kind of emission-control equipment is complex, difficult in maintenance, service life is short, when needs are changed or overhaul emission-control equipment, boiler waste gas just cannot be carried out processing, and which results in the pollution of environment.
Summary of the invention
It is an object of the invention to provide a kind of flue gas initial filter device for coal-burning boiler, simple in construction, easy to use, can use inside coal-burning boiler by device, be possible not only to waste gas is tentatively filtered, be more easy for when boiler exterior overhaul of the equipments and still waste gas can be filtered.
The purpose of the present invention is achieved through the following technical solutions:
A kind of flue gas initial filter device for coal-burning boiler, including the first air inlet pipe, right angle connecting tube, the second air inlet pipe, first filter cylinder, exhaustor, described first air inlet pipe connects connecting tube one end, right angle mouth of pipe, the described right angle connecting tube other end mouth of pipe connects the second air inlet pipe, described second air inlet pipe upper end connects just filter cylinder, described just filter cylinder top device exhaustor;Described first air inlet pipe interior arrangement is with the fireguard of hollow out mouth;Described second air inlet pipe interior arrangement granule foreign screen plate;The described just supreme device pps PO PE NT PTFE in cartridge interior bottom right, ceramic capillary drainage screen.
All brushing fire resistant coating on described first air inlet pipe, right angle connecting tube, the second air inlet pipe, first filter cylinder, exhaust tube wall.
Described initial filter cylinder shell is made up of shell body, thermal insulation layer, inner housing, and described thermal insulation layer device is between shell body and inner housing, and described thermal insulation layer adopts asbestos insulation plate.
A kind of flue gas initial filter device for coal-burning boiler of the present invention, in use, flue gas in boiler internal smoke chamber enters from the first air inlet pipe, first air inlet pipe interior arrangement is with the fireguard of hollow out mouth, the Mars in flue gas or spark can be blocked, then flue gas enters to right angle connecting tube through the first air inlet pipe, second air inlet pipe, in the second air inlet pipe, device granule foreign screen plate, the large granular impurity in flue dust can be filtered out, then flue gas enters in first filter cylinder, pps PO PE NT PTFE through the supreme device in first cartridge interior bottom right, after ceramic capillary filter screen filtration, discharge from exhaustor.
Beneficial effects of the present invention: a kind of flue gas initial filter device for coal-burning boiler of the present invention, simple in construction, easy to use, can device at boiler internal, be possible not only to waste gas is tentatively filtered, be more easy for when boiler exterior overhaul of the equipments and still waste gas can be filtered.
