Description
Technical field
The invention belongs to industrial heat exchanger chemical cleaning fields, and in particular to a kind of circulating plant condenser is changed online
Learn cleaning method and system.
Background technique
Shell and tube water cooler is to be widely used in the industrial departments such as power, chemical industry, petroleum and atomic energy mainly to assist setting
It is one of standby, it is responsible for various power, electrical, the mechanically and chemically important cooling task of consersion unit, the quality of working performance
There is important influence to the safe and economical operation of enterprise.In diabatic process, in shell and tube water cooler in heat exchanger tube water side
Wall has a adverse impact due to being influenced easily to form scale and spot, the performance of heat exchanging device by heating and water quality, how and
When to remove scale and spot be always a major issue urgently to be resolved.By taking power plant as an example: condenser is exactly a kind of shell and tube
Water cooler: by thousands of set of heat exchange tubes at, pipe it is outer walk steam, cooling water is walked in pipe, because there is a presence of heat exchange, in cooling water
Salt be constantly precipitated during laser heating, form a large amount of scale and be attached on tube wall, lead to vacuum in condenser
Decline, gross coal consumption rate rise, and cost of electricity-generating increases, therefore reduce the efficiency of Turbo-generator Set.Work as condenser fouling
0.5mm or so can make vacuum degree drop to 85% hereinafter, making coal consumption for power generation increase 15~20g/kWh, for one by 90% or more
It operates 7000h platform year, for the 300MW unit that rate of load condensate is 90 %, about 28~380,000 t of standard coal will be consumed every year, if water more
Dirty thickness reach 1mm, then not only more coal consumptions will more than annual more than 50,000 tons, but also will affect 10% power output.It is true in condenser
Sky decline, can also be such that the exhaust temperature of steam turbine increases, lead to the deformation of low pressure (LP) cylinder, not only influence the economy of power plant's operation,
Also directly affect the operational safety of Turbo-generator Set.The present invention proposes there is needle with minute quantity aiming at this problem
To property, specific chemical, online chemistry, which accurately cleans one kind, to be realized to scale in shell and tube water cooler and spot
Technological system.
In the following, the method for the common similar on-line cleaning of the present invention and power plant is carried out one by taking plant condenser as an example
A comparison:
1) condenser ball cleaning method (this method be power plant's standard configuration): then putting into a large amount of glueballs in condenser water, glueballs with
Recirculated water flowing is exchanged heat pipe and is cleaned by heat exchange tube of condenser, although it can play the role of certain scale removal, by
Cannot too big, be too otherwise difficult to firmly through heat exchange tube of condenser in glueballs, but it is too small, too soft, will affect scale removal effect again, lead
The glueballs rate of recovery is caused to reduce.In addition, rubber ball cleaning method additionally depends on the flow velocity of recirculated water, winter circulating water temperature is low, and flow is not
Can be big, hot-well depression otherwise can be generated, the decline of unit performance driving economy decline flow is caused to lead to water flow velocity in heat exchanger tube
Decline, rubber ball cleaning effect decline, condenser clean rate decline, minimum reachable 0.4 (design value 0.85).For water in use
The system for doing recirculated water, effect is with regard to worse, therefore how to make good use of glueballs is also always the problem for perplexing power plant.CNK or more can
It finds and has largely turned out this point, but problem same after operation a period of time after transformation about the improved article of glueballs
It will appear again, illustrate that rubber ball cleaning inherently exists and rely on recirculated water flow velocity, ball collecting rate and cleaning effect are difficult to satisfactory to both parties great
Defect.
2) condenser in-site chemical cleaning method: present power plant substantially without exception will be in investment rubber ball cleaning
On the basis of a large amount of chemical is added in condenser circulating water pond (mainly acid, corrosion inhibiter and algicide is the row of neutralization
A large amount of alkali will be added by releasing), to prevent the growth of heat exchanger tube fouling and algae.As unit capacity increases, circulating cooling water
Increasing, 300MW unit is 40000t/h or so, and cooling tower circulating cooling evaporated quantity of water is about 2600t/h, 600MW,
1000MW unit is with regard to more, in order to guarantee scale inhibition, sterilization effect, maintains the low pH value of recirculated cooling water, dosage as one can imagine,
By taking 300MW unit as an example, the expense of dosing in 1 year is about 2,000,000 yuan or so.Nevertheless, to water in use, (there is regulation in country
Electric power plant circulating water must use in water, to avoid underground water is used) unit as circulating cooling water of power plant, effect is simultaneously unknown
Aobvious, many units are because fouling seriously has to carry out facing during operation to stop cleaning, to guarantee the safety of unit operation.
The main problem of this cleaning method is: the chemical of addition, dilute by recirculated water a large amount of in circulating water pool
It releases, cleaning concentration is much not achieved when to heat exchange tube of condenser, has wasted a large amount of chemicals.
