Description
Technical field
A kind of present invention gas furnace burner noz(zle) clean method, it is related to and a kind of gas furnace burner noz(zle) is being cleaned
Method, belong to thermal power generation field.More particularly to a kind of cost is relatively low, the good gas furnace burner noz(zle) cleaning side of cleaning effect
Method.
Background technology
At present, the gas furnace burner noz(zle) of power plant in use for some time, due to the reason such as insufficient of burning, in nozzle
Each passage can be blocked, because this gas furnace burner noz(zle) belongs to key equipment, directly affect the work of gas furnace,
Not timing is needed clean, and because the gas furnace burner noz(zle) of power plant belongs to expensive precision equipment, it is complicated, it is interior
The multigroup asphalt channel in portion, the diameter of passage is small, and passage is tortuous, and there be multiply shunting end, end shunt position wall thickness compared with
Small, domestic traditional cleaning can not meet channels clean requirement, so, Current Domestic power plant, all it is to fire gas furnace
Burn nozzle and be sent to foreign countries, supplier that please be external is cleaned, a cleaning charge costliness, single cleaning gas furnace burner noz(zle)
Spend between 3-3.5 ten thousand, each gas furnace one group 21, and the cleaning frequency is average at 45 days, to clean within 1 year 8 left sides
The right side, a cleaning charge just needed nearly 6,000,000 altogether in 700,000 or so, one years one group of cleaning charges, the combustion gas in extreme influence power plant
Stove normal work and profit, and the cleaning frequency of every group of gas furnace burner noz(zle), some local damage ratios are more serious, cycle contracting
It is as short as averagely 30 days, or even the shorter time, each passage in nozzle can be blocked, and therefore, the maintenance cost of nozzle is high.
And gas furnace burner noz(zle) is changed, existing market valency just needs 1,500,000 or so in 70,000 or so one, one group 21, greatly increases
Add the operating cost of power plant, at present at home, also no producer possesses the technical strength for cleaning this gas furnace burner noz(zle),
International vendor is limited by, many power plant can all select directly to buy new burner noz(zle) use to not influence the production and operation.
Our factory technical staff passes through the research and development more than 3 years, tentatively possesses the technical capability of this nozzle of cleaning, by burner noz(zle)
The parameters of cleaning process are attempted, and have reached and the gas nozzle of gas furnace is cleaned, and do not destroyed nozzle body
Method and technological process, and the technique of clean gas stove gas nozzle is primarily determined that, postorder will also be further
It is improved, has saved power plant's production cost, reduces because gas stove nozzle is atomized the uneven energy waste brought.
The content of the invention
In order to improve the above situation, it is relatively low that a kind of gas furnace burner noz(zle) clean method of the present invention provides a kind of cost,
The good gas furnace burner noz(zle) clean method of cleaning effect.Cleaning performance is good, does not destroy nozzle body, convenient and practical.
A kind of gas furnace burner noz(zle) clean method of the present invention is realized in：A kind of gas furnace burner noz(zle) of the present invention
Clean method, it is characterised in that comprise the following steps：
1）Demolition diaphragm gas stove gas nozzle first, then place and cooled down in 5-10min；
2）Gas furnace gas nozzle is put into container；
3）The cleaning agent being slowly injected into container after modulation so that cleaning agent water level is higher than gas furnace gas nozzle peak,
Immersion 15-20min for the first time, in immersion process, manually swing a gas furnace gas nozzle every 3-5 min so that oil circuit
Gas in passage is discharged as far as possible；
4）Then gas furnace gas nozzle is spun upside down 180 °, then soaks 15-20min；
5）Gas furnace gas nozzle is taken out, drains cleaning agent in oil line pipe；
6）Then the first connector on base is connected by reducing adapter sleeve with high-pressure water pipe, water under high pressure uses 20-
22Mpa, water use running water；
7）Gas furnace gas nozzle shower nozzle one end is put into clean container；
8）The residue corresponding to the first connector in oil line pipe is blown out from central passage by high-pressure water pipe；
9）In cleaning process, intermittent switch is carried out to high pressure water circuit；
10）The water free from admixture of gas furnace gas nozzle central passage discharge；
11）Then second pipe connector is changed, oil line pipe corresponding to second pipe connector is cleared up, repeats 9,10
Step, until the equal no-sundries of water of orifice discharge；
12）Repeat step 9,10 causes standby orifice impurity emptying；
13）Into cleaning detecting step, after the completion of cleaning detection, whole cleaning process terminates.
Cleaning detection method, comprises the following steps used in a kind of gas furnace burner noz(zle) clean method of the present invention：
1）Gas furnace gas nozzle shower nozzle one end is taken out out of container, then proceedes to connect water under high pressure, by observing water under high pressure
In the atomization situation of gas furnace gas nozzle nozzle end, corresponding pipeline atomization situation is detected；
2）Reducing connecting tube is dismantled, the first connector, the second connector will be sequentially connected, atomization detection is carried out to asphalt channel；
3）Meet requirement after inspection, water under high pressure closed, change high pressure gas and dried up, successively with the first connector, the
Two connectors and joint among three members connection, asphalt channel residual moisture is dried up.
The modulator approach of cleaning agent used in a kind of gas furnace burner noz(zle) clean method of the present invention, it is characterised in that bag
Include following steps：
1）Using aqueous cleaning agent, alkalescent；
2）Cleaning agent plus water are diluted, original liquid concentration is 72%-80% after dilution, and viscosity reduces after allotment, and viscosity requirement is used
Glass bar, which dips in, occurs without wire drawing；
3）Stir standby.
The cleaning agent modulation dilution ratio is to find balance between viscosity and concentration, ensure that cleaning agent in oil
Circulation in the pipeline of road, also ensure that capable of washing dose of alkalescent；
In the cleaning method, the purpose for being slowly injected into cleaning agent is to be stepped into order that obtaining cleaning agent in oil line pipe, is made
The gas obtained in pipeline can be discharged, and be avoided because cleaning agent injection is too fast so that internal gas discharge difficulty, forms negative pressuren zone；
The selection of the high-pressure water pressure is to protect orifice thin-wall regions；The purpose of the intermittent switch of the water under high pressure
Be in order that water jet carries out the impact of interval in asphalt channel, be easy to the cleaning of particle；
Reach the purpose cleaned to gas furnace gas nozzle.
Beneficial effect.
