Smoke-discharging tower integration device

Abstract

This invention provides a smoke tower syncretic device. It can fulfill the operations of smoke discharging and cooling at the same time. It includes: tower body, on which lateral wall is arranged with holes for smoke channels; fiberglass reinforced plastics smoke channels extending from the holes on the lateral wall into the tower body; center cylinder which introduces circulating water from lower part and raise the water up to the preset height; water spraying device which accepts the raised circulating water and sprays the water downwards. Thus, it uses cross-ventilation to cool the water; water collecting machine which accumulates the falling water sprayed from the water spraying device. This invention saves the cost of chimney construction, chimney corrosion protection and baffle door assembling.

Description

technical field [0001] The invention relates to a smoke tower integrated device in a power station, in particular to a smoke tower integrated device which uses a cooling tower as a smoke exhaust device and realizes two operations of smoke exhaust and cooling through only one tower. Background technique [0002] In the past construction of power stations, the clean flue gas after desulfurization by the absorption tower generally passes through the steel flue with anti-corrosion treatment inside, and then enters the chimney for discharge after being heated by GGH (flue gas heater); or the clean flue gas passes through the internal anti-corrosion treatment The steel flue is discharged through a chimney lined with titanium steel plate (or other anti-corrosion treatment). In addition, in a power station, it is usually necessary to cool the circulating water used in the work, for which a cooling tower is usually used, and the cooling tower is installed separately.

AI Technical Summary

Problems solved by technology

Due to the installation of chimneys and cooling towers, coupled with the devices attached to the two, the construction of the power station takes up a lot of space, and the project investment is also high

[0004] Although the existing technology is relatively mature, as mentioned above, the biggest disadvantages are complex structure, large site occupation and high engineering investment.

Regarding the separate arrangement of chimneys and cooling towers, in the first case, it is necessary to increase the cost of GGH, making the site arrangement behind the furnace more crowded, increasing operation and maintenance costs, and also increasing investment; in the second case, although No increase in GGH, but anti-corrosion treatment must be carried out on the chimney. This project is also a high-investment and difficult job

At the same time, the steel flue needs anti-corrosion treatment, which also increases the project investment.

Not only that, in both cases, the whole system is also equipped with components such as baffle doors, which also increases the cost of investment and operation and maintenance
