Abstract
An external wall cooling water device which is used in the field of boilers of thermal power plants comprises a cold ash hopper, a water inlet main pipeline and short pieces. A circle of water inlet main pipeline is disposed on the outer surface of the cold ash hopper, the short pieces are fixed on the water inlet main pipeline, a plurality of inserting holes corresponding to the short pieces are disposed on the upper portion of the cold ash hopper, metal short pipes respectively penetrate into the inserting holes, and one end of each metal short pipe is fixedly connected with the wall of the cold ash hopper while the other ends of the metal short pipes are respectively connected with the corresponding short pieces on the main pipeline via hoses. The circle of wall cooling water feeding main pipeline is disposed outside the cold ash hopper, and an internal wall cooling water pipe is changed into an external wall cooling water pipe, thereby being capable of effectively preventing the wall cooling water pipe dropping into a slag crusher to damage the same, avoiding equipment accidents and casualties, and preventing a flame retardant coating from dropping to wear the cold ash hopper due to blocking of wall cooling water. In addition, the external wall cooling water device is simple in structure and convenient and fast in installation, can prolong service life of equipment, avoids blowing-down overhaul, and is extremely convenient in overhaul and maintenance.
Description
Technical field
The utility model relates to the cold wall water of the external device that use in a kind of thermal power plant boiler field.
Background technology
At present, what thermal power plant boiler used is the cold wall water pipe of internally-arranged type, because the cold wall water pipe of internally-arranged type is in heating status in the boiler operatiopn midium or long term, following situation very easily occurs:
Often stop up because of the tube wall fouling causes osculum, make to occur the lack of water or the situation of cutting off the water supply in the furnace hopper, cause the flame retardant coating in the furnace hopper to come off, the outer wall steel plate wearing and tearing aggravation of furnace hopper, essential blowing out when cold wall water pipe is changed.
Cold wall water pipe occurs and be blown when being shed in the slag crusher situation, the maintenance danger very of getting up brings very big hidden danger for the safety of the boiler plant stable operation and the person;
After the built-in cold wall water pipe fracture, cold wall water, causes heating surface and leaks the accident that blowing out occurs under soot particle and water erosive wear because upwards spray of the effect of negative pressure can directly be sprayed onto on the boiler heating surface;
Because cold wall water pipe damages or blocks, when cutting off the water supply in the furnace hopper, the ash in the furnace hopper is deposited in the top of slag crusher, and the scald accident takes place the high dry ash of outside spray heat that is interrupted in the inspection opening easily.
Summary of the invention
Goal of the invention of the present utility model is the many deficiencies at prior art, provides a kind of simple in structure, guarantees stable operation of the boiler, guarantees the cold wall water of the external device of the person and device security.
Realize above-mentioned purpose by the following technical solutions: the cold wall water of a kind of boiler externally positioned type device, comprise the boiler furnace hopper, water inlet trunk line, pipe nipple, the outer surface of described furnace hopper is provided with a circle water inlet trunk line, be consolidated with many pipe nipples on this water inlet trunk line, described furnace hopper top is corresponding with many pipe nipples to be provided with a plurality of jacks, and the metal short tube penetrates in the jack respectively, one end is fixedlyed connected with the furnace hopper wall, and the other end is connected with pipe nipple on the trunk line corresponding with it with flexible pipe respectively.
Adopt technique scheme, the cold wall water of the utility model device, the former built-in cold wall water pipe of boiler is removed, arrange the cold wall water service main of circle road along the outer surface of furnace hopper, change built-in cold wall water pipe into external cold wall water pipe, compared with prior art, external cold wall water pipe can effectively prevent from because of cold wall water pipe falls in the slag crusher equipment to be caused damage, avoids the generation of equipment and personal injury; Avoid owing to, furnace hopper is caused wearing and tearing because of cold wall water interrupts causing coming off of flame retardant coating.This apparatus structure is simple, and it is convenient to install.Use this device can prolong the service life of equipment, avoid shutdown maintenance, overhaul, safeguard very convenient.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure, jack 1, short tube 2, heating surface lower collecting box 3, hose 4, indicator 5, water inlet trunk line 6, furnace hopper 7, pipe nipple 8.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
Present embodiment is the cold wall pipe device of a kind of thermal power plant boiler external, sees Fig. 1, by boiler furnace hopper 7, and compositions such as water inlet trunk line 6, pipe nipple 8.Furnace hopper 7 is positioned at the bottom of boiler heating surface lower collecting box 3.Along the outer surface of furnace hopper 7 a circle water inlet trunk line 6 is installed, at 32 pipe nipples 8 of water inlet trunk line 6 equal intervals welding, pipe nipple 8 is steel tube, is spaced apart 400mm, every pipe nipple 8 high 150mm between the many pipe nipples (pipe nipple and pipe nipple).The top of furnace hopper 7 and the pipe nipple 8 corresponding jacks 1 that bore 32 φ 40mm, corresponding with 32 jacks, the stainless steel tube of processing 32 long 300mm, φ 32mm is as short tube 2,2 one of short tubes are processed into hangnail, a weldering is dead, at the apopore (angle in 3 holes is in 90 ° of scopes) that is close to 3 φ 5mm of weldering dead end brill.The end with holes of stainless steel short tube 2 is penetrated respectively in each self-corresponding jack 1, be inserted in the furnace hopper 7, fix with the furnace hopper wall, other end band hangnail end is formed the cold wall pipe device of external with hose 4 external stability that is connected with pipe nipple 8 on the water inlet trunk line 6 corresponding with it.Add weldering one joint indicator 5 (consistent with the direction in getting out water hole, as to guarantee being directed downwards of water inlet) in the outside of short tube 2.
The medium temperature and medium pressure boiler adopts this device, operates steadily, and effect is obvious.
Claims (2)
1. the cold wall water of boiler external device, comprise furnace hopper, water inlet trunk line, pipe nipple, it is characterized in that the outer surface of described furnace hopper is provided with a circle water inlet trunk line, is consolidated with many pipe nipples on this water inlet trunk line, described furnace hopper top is corresponding with many pipe nipples to be provided with a plurality of jacks, the metal short tube penetrates respectively in the jack, and an end is fixedlyed connected with the furnace hopper wall, and the other end is connected with pipe nipple on the trunk line corresponding with it with flexible pipe respectively.
