Abstract
A coal-fired boiler steam blowing system hydrophobic recycling device is characterized in that every hydrophobic discharge port (1, 2, 3, 4) of an original blowing system is connected and centralized to a main pipe (5) through a pipeline, then three paths of branch pipes (6, 7, 8) are connected to the main pipe (5), a first branch pipe (6) removes an original discharge system, and an electrically operated gate (11) is mounted on the first branch pipe; a second branch pipe (7) removes a condenser hot well (9), and an electrically operated gate (12) is mounted on the second branch pipe; a third branch pipe (8) removes a deaerator water tank (10), and an electrically operated gate (13) is mounted on the third branch pipe; and a controller is arranged to control each of electrically operated gates to achieve remote control. The coal-fired boiler steam blowing system hydrophobic recycling device can recycle water of coal-fired power plants, which is originally discharged to surrounding waters or other places, and can play a role in energy conservation and environmental protection.
Description
Technical field
The utility model relates to a kind of coal-burning boiler Steam Soot-Blower System drain recovery use device.
Background technology
For the coal-fired station of the above grade of 200MW, be bonded in burner hearth and other heating surfaces surface in order to alleviate the lime-ash that produces behind the raw coal combustion, affect heat exchange, during the boiler erection, easily all arranged steam sootblower by the position that lime-ash bonds at each.Steam sootblower vapour source is generally extracted from the curtain wall import of boiler, and steam pressure does not generally wait in the 16MPa-25MPa interval because of the different to some extent difference of unit output, and the temperature of steam is in 350-450 degree centigrade of interval.Unit blows grey 2-3 time under normal circumstances every day, because soot blower system pipeline layout is long, for vibration and the thermal shock that reduces pipeline, begin at every turn to blow that must to carry out heating coil with steam before the ash hydrophobic, the hydrophobic time is 10 minutes, hydrophobic generally through the cooling after directly enter catch-basin, do not reclaim.This system layout mode can produce thermal pollution to environment on the one hand; For resource, be to belong to wasting of resources behavior on the other hand.
The utility model content
Technical problem to be solved in the utility model just provides a kind of coal-burning boiler Steam Soot-Blower System drain recovery use device that can not produce thermal pollution and economize on resources environment.
Solve the problems of the technologies described above, the technical solution adopted in the utility model is as follows:
A kind of coal-burning boiler Steam Soot-Blower System drain recovery use device, it is characterized in that: each drain discharge mouth of soot blower system is aggregated into a female pipe with the pipeline connection, then from female Guan Shangjie three road arms, the first via is removed original exhaust system (being defined as the A road); The second the tunnel removes condenser hotwell (being defined as the B road); Third Road removes deaerator storage tank (being defined as the C road).
On the basis of the above, the utility model can also be done further improvement:
On described each arm Electrically operated gate is installed all, realizes distant place control.
Use step of the present utility model:
Step 1: if the soot blower system pipeline has service work in the recent period, may there be silt or welding discarded object in the pipeline, the hydrophobic A road of walking of system's this moment, directly discharging, until pipeline purges totally, steam quality is qualified.
Step 2: if system in the recent period without service work, normal operation, blow grey program start after, at first open the B road, drain discharge was opened 60 seconds to condenser.In this stage, 1 annual system of 300MW unit can reclaim approximately 50 tons of demineralized waters, and 1 annual system of 600MW unit can reclaim approximately 100 tons of demineralized waters, and 1 annual system of 1000MW unit can reclaim the demineralized water hundredweight,
Step 3: open the C road, close the B road, drain discharge is to deaerator storage tank, until hydrophobic end (the whole hydrophobic time is generally 600 seconds, and this time, each power plant slightly had any different).1 annual system of 300MW unit can reclaim approximately 450 tons of demineralized waters, reclaims heat and is equivalent to 50 tons of mark coals; 1 annual system of 600MW unit can reclaim approximately 900 tons of demineralized waters, reclaims heat and is equivalent to 100 tons of mark coals; 1 annual system of 1000MW unit can reclaim approximately 1100 tons of demineralized waters, reclaims heat and is equivalent to 120 tons of mark coals.
Step 4: after hydrophobic process finished, A, B, C three tunnel all closed, and soot blower system begins to blow ash.
Beneficial effect: the utility model can be with coal-burning boiler Steam Soot-Blower System drain discharge to condenser hotwell or be disposed to the deoxygenation water tank of oxygen-eliminating device.Utilize the utility model patent, can originally be disposed to the coal-burning power plant this part water recycling in peripheral waters or other places, can reach the effect of playing energy-saving and environmental protection.
The investment of this plant modification needs ten thousand yuan of 5-6, by 900 yuan/tons of calculating of mark coal price lattice, take the 300MW unit as example, uses this patent, moves 1 year and can recoup capital outlay.The unit of 600MW and 1000MW is used this patent 6-7 month and can be recouped the investment.
