Abstract

The utility model discloses a boiler stove bottom water sealed tank washing unit solves the technological problem of the difficult clearance of water sealed tank inner product sediment, and it includes interior outer casing, and the female pipe of annular moisturizing in the interior outer casing outside sets up a plurality of annular moisturizing branch pipe in the female intraductal side of annular moisturizing, sets up the female pipe of intaking on the female pipe of annular moisturizing, characterized by: intake to set up separately on female pipe and wash female pipe, wash female pipe and set up the water supplying valve door with the female intertube of annular moisturizing, wash the annular moisturizing branch pipe that female pipe extended to the stove bottom right side, set up the sparge water valve with an annular moisturizing intertube washing female pipe, set up on the left annular moisturizing branch pipe of stove bottom and wash the blowdown valve, the internal chiasma mouth of a plurality of annular moisturizing branch pipes sets up the moisturizing elbow along clockwise, and this utility model not only can effectively guarantee ashless slag deposits in the water sealed tank, and it is sealed to prevent that water seal lack of water, boiler bottom from losing, has effectively guaranteed heating part inflation sufficient clearance occasionally moreover, has ensured the boiler safety operation of stabilizing the economy.

Description

Boiler Furnace bottom seal groove flusher

Technical field

The utility model relates to removing or the processing technology field of combustion residue, specifically relates to a kind of Boiler Furnace bottom seal groove flusher.

Background technology

The effect of furnace bottom water seal is mainly to utilize industry water to realize sealing, keep combustion chamber draft stable, prevent that gas leakage from affecting combustion conditions, make the heating parts such as water-cooling wall can free shrink or expansion simultaneously, in addition, furnace bottom water seal also has the effect of collection and cooled slag, industry water is in the time extinguishing cinder Mars, can cause cinder to splash, cause the interior dust stratification accumulated slag of water sealed tank serious, thereby affect water seal water replenishing and boiler bottom sealing, therefore, the staff of power plant can regularly clear up dust stratification accumulated slag in water sealed tank, the manner of cleaning up using is at present after blowing out, carry out apertured conditioning by staff, this manner of cleaning up expends a large amount of manpower and materials, and operating efficiency is low.

Utility model content

The utility model discloses a kind of Boiler Furnace bottom seal groove flusher, solves the not technical barrier of easy to clean of accumulated slag in water sealed tank, ensures that boiler seal and heating part expand unaffected.

Technical scheme: a kind of Boiler Furnace bottom seal groove flusher, comprise outer casing in water sealed tank, be arranged on the female pipe of annular moisturizing in interior outer casing outside, evenly be arranged on the some annular moisturizing arm of the female pipe of annular moisturizing inner side, and the water inlet mother who is arranged on the female pipe of annular moisturizing manages, it is characterized in that: on the female pipe of water inlet, set up separately and rinse female pipe, rinse between the female pipe of female pipe and annular moisturizing moisturizing valve is set, rinse the annular moisturizing arm that female pipe extends to furnace bottom right side, female the pipe between annular moisturizing arm of flushing, flushing water valve is set, on the annular moisturizing arm in furnace bottom left side, flushing pollution discharge valve is set, the interior crossing of described some annular moisturizing arms arranges moisturizing elbow along clockwise direction.

Beneficial effect: this utility model not only can effectively ensure in water sealed tank, without ash deposition, to prevent that water seal lack of water, boiler bottom from losing sealing, and effectively to have ensured when heating part expands have sufficient clearance, has guaranteed the boiler safety operation of stabilizing the economy.

Brief description of the drawings

Accompanying drawing 1 is the structural representation of the present embodiment.

Detailed description of the invention

With reference to accompanying drawing 1, a kind of Boiler Furnace bottom seal groove flusher, comprise outer casing 2 in water sealed tank, be arranged on the female pipe 4 of annular moisturizing in the outside of interior outer casing 2, evenly be arranged on the some annular moisturizing arm 3 of the inner side of the female pipe 4 of annular moisturizing, and the water inlet mother who is arranged on the female pipe 4 of annular moisturizing manages 6, on the female pipe 6 of water inlet, set up separately and rinse female pipe 8, rinse between the female pipe 4 of female pipe 8 and annular moisturizing moisturizing valve 7 is set, rinse the annular moisturizing arm 3 that female pipe 8 extends to furnace bottom right side, between the female pipe 8 of flushing and annular moisturizing arm 3, flushing water valve 9 is set, on the annular moisturizing arm 3 in furnace bottom left side, flushing pollution discharge valve 1 is set, the interior crossing of described some annular moisturizing arms 3 arranges moisturizing elbow 5 along clockwise direction.

This utility model installs high flux flushing pipeline and valve additional on water sealed tank right side, all install moisturizing elbow additional in water sealed tank moisturizing arm inside simultaneously, not only strengthen water sealed tank inner sealing water flow, and set elbow makes the current in water sealed tank form annular water flow, will flow along annular water flow if any a small amount of lime-ash, be difficult for deposition, so regular use high flux flushing water rinses lime-ash in water sealed tank, then discharge from furnace bottom right side flushing pollution discharge valve, complete the flushing operation of this utility model.

This utility model drops into test application in Datang northern Shandong Power Generation Corporation Ltd., regularly carries out the flushing of water sealed tank dust stratification, in existing water sealed tank dust stratification accumulated slag situation be improved significantly.

Claims
