Description
Technical field
It the utility model is related to waste heat boiler area of maintenance, more particularly to waste heat boiler furnace mouth seal device.
Background technology
Waste heat boiler, as the term suggests refer to utilize waste gas, waste material or waste heat in waste liquid in various industrial process and its
Caused heat is heated to water in the boiler of certain temperature after combustible burning.Recycled with smoke box, flue residue heat
Oil burning boiler, gas fired-boiler, coal-burning boiler are also referred to as waste heat boiler, and waste heat boiler can produce hot water or steaming by waste heat recovery
Vapour uses to supply other workshop sections.Its operation principle is as follows：Fuel oil, combustion gas, the coal-fired burning generation high-temperature flue gas that passes through discharge heat
Amount, high-temperature flue gas are introduced into burner hearth, enter back into the waste-heat recovery device of front smoke box, subsequently enter smoke-fire-tube, finally enter rear cigarette
Waste-heat recovery device in case flue, high-temperature flue gas become low-temperature flue gas and are discharged into air through chimney.Due to waste heat boiler greatly
The utilization rate of the heat of fuel combustion release is improved, so this boiler extremely saves.Its mainly by drum, movable gas hood,
Fire door section flue, oblique 1 section of flue, oblique 2 sections of flues, last 1 section of flue, last 2 sections of flues, charge pipes（Blanking chute）Groove, oxygen rifle mouth, nitrogen
Seal apparatus and nitrogen blocking, manhole, differential pressure pressure obtaning device, the bearing of flue and suspension bracket etc. form.Waste heat boiler is divided into six
Circulation loop, each circulation loop are made up of down-comer and tedge, and each section of flue feedwater is incorporated into from drum by down-comer
Entering each heating surface after the lower header of each flue, water enters import header by producing steam after heating surface, then by tedge
Introduce drum.Connected between each flue with flange.
In waste heat boiler running, pipe explosion accident occurs when boiler uptake flue or downward-flow flue heating surface, it is necessary to
Blowing out cooling is rushed to repair.For ease of fast cooling and observation leakage point, furnace mouth seal device need to be dismantled, sealing device
Be flexible coupling by boiler and formed with skirt cover, between connected by flange bolt, by manually being cut bolt one by one during dismounting, shift
Skirt cover.Four pieces of skirt covers and the sealing that is flexible coupling are removed completely needs about 6 people 4 hours, how quickly to carry out sealing device dismounting, enters
Row boiler cools, and it is the place for being worth inquiring into and thinking deeply to mitigate person works' intensity.
Utility model content
The technical problems to be solved in the utility model is that inconvenient maintenance after pipe explosion accident, sealing occur for existing waste heat boiler
The device dismounting slow efficiency of speed is low, and intensity of workers is big, and a kind of elevated waste heat boiler fire door sealing is provided for this
Device.
The technical solution of the utility model is：Elevated waste heat boiler furnace mouth seal device, it includes uptake flue water
Cold wall, the soft seal being fixed on the inwall of uptake flue water-cooling wall and the skirt cover for being fixed in soft seal bottom, the rising cigarette
Also be connected with the inwall of road water-cooling wall can lifting skirt cover hoisting mechanism.
Hoisting mechanism described in such scheme includes the inwall for being fixed in the uptake flue water-cooling wall above soft seal
On keeper, the end detachable connection of the keeper has the vertical connection for extending downwardly and being spaced apart with soft seal
Part, the bottom of the vertical connections are affixed by the bottom or skirt cover of transition piece and soft seal.
Vertical connections described in such scheme are screw rods, and the screw rod coordinates with keeper screw thread.
Vertical connections described in such scheme include with keeper screw thread coordinate top nut and with transition piece screw thread
The lower nut of cooperation, the top nut and lower nut are connected as a single entity by hollow sleeve.
Vertical connections described in such scheme include affixed vertical guide rail on the positioning element and adapt to guide rail by electricity
Machine drives vertically moving piston rod.
Soft seal is curved described in such scheme.
The beneficial effects of the utility model are when accident occurs for the vertical flue of boiler, first dismantle skirt cover bottom mounting flange
Bolt, the boiler skirt cover of fire door surrounding is then directly lifted by lifting device, reduced because boiler tube bursting dismounts skirt cover and soft company
The plenty of time of cost is connect, improves first-aid repair efficiency, reduces workload.

Embodiment
Below in conjunction with the accompanying drawings and embodiment is described further to the utility model.
As shown in figure 1, the utility model includes uptake flue water-cooling wall 4, is fixed on the inwall of uptake flue water-cooling wall
Soft seal 3 and be fixed in the skirt cover 2 of soft seal bottom, being also connected with the inwall of the uptake flue water-cooling wall can lifting skirt
The hoisting mechanism 1 of cover.
Soft seal of the present utility model refers to the sealing device with certain deformation quantity, when hoisting mechanism is lifted up skirt cover
When skirt cover contact and extrude with soft seal, the space risen for skirt cover is conceded by the deformation of soft seal, and then reserved
Space observation leakage point and cooling.
The utility model is elaborated with reference to embodiment.
Embodiment 1：Elevated waste heat boiler furnace mouth seal device, it includes uptake flue water-cooling wall 4, is fixed in rising
Soft seal 3 and the skirt cover 2 for being fixed in soft seal bottom, the inwall of the uptake flue water-cooling wall on the inwall of flue water-cooling wall
On be also connected with can lifting skirt cover hoisting mechanism 1.Hoisting mechanism includes being fixed in the uptake flue water above soft seal
Keeper 6 on the inwall of cold wall, keeper integral level distribution are in plate-shaped or strip-shaped, and the end thread of the keeper connects
