Description

Boiler flue gas condensate water is from drainage system

Technical Field

The utility model belongs to the technical field of boiler flue drainage, and particularly relates to a boiler flue gas condensate self-drainage system.

Background

When the flue gas condensate water of the boiler flue of a company is treated, the flue gas condensate water is firstly collected into a water collecting tank at the bottom of a chimney through a downpipe, then is pumped by a waste water pump and is conveyed to a boiler desulfurization tower, and the flue gas condensate water of the boiler has certain corrosiveness, so that the waste water pump is corroded, the machine sealing water is serious, equipment is frequently overhauled, water accumulation at the bottom of the chimney is serious, the flue corrosion leakage and the overflow of the waste water tank are accelerated, and the flue gas condensate water can only be output to the boiler desulfurization tower through a submersible sewage pump and a fire-fighting belt.

Disclosure of Invention

The utility model provides a boiler flue gas condensate self-drainage system aiming at the problems.

The utility model adopts the following technical scheme to achieve the aim:

the utility model provides a boiler flue gas condensate water is from drainage system, includes the flue body be provided with the toper collecting pipe in the flue body the lower part of toper collecting pipe is connected with the drain pipe, the other end of drain pipe is connected with the boiler desulfurizing tower.

Further, a conical connecting piece is arranged between the drain pipe and the conical water collecting pipeline, the diameter of the upper end of the conical connecting piece is the same as that of the lower end of the conical water collecting pipeline, and the diameter of the lower end of the conical connecting piece is the same as that of the drain pipe.

Still further, a U-shaped pipe is provided on the drain pipe.

Further, the U-shaped tube is a transparent tube.

Further, an anti-corrosion coating is applied to the inner wall of the tapered connector.

Further, the drain pipe is a stainless steel pipe.

Compared with the prior art, the utility model has the following advantages:

according to the utility model, the self-drainage of the boiler condensate is realized by utilizing the height difference between the conical water collecting pipeline and the boiler desulfurization tower, and meanwhile, the conical connecting piece is used for connecting the drain pipe and the conical water collecting pipeline, so that the boiler condensate is prevented from staying at the bottom of the conical water collecting pipeline for a long time, and the inner wall of the conical connecting piece is coated with the anti-corrosion coating, so that the service life of the conical connecting piece can be prolonged;

the utility model sets the U-shaped pipe to prevent the negative pressure of the chimney from sucking cold air to affect drainage and environmental protection on-line oxygen content by utilizing the water seal principle, and meanwhile, the U-shaped pipe is transparent and can observe drainage condition at any time;

the utility model utilizes the height difference to realize the self-drainage of the boiler condensate, does not need to use a water pump, saves electricity consumption by about 9 kilo-second per year, and saves accessory materials and labor cost by about 5 kilo-second per year by combining more than 4 kilo-second.
