Abstract

The utility model discloses a vacuum drainage device of a desulfurizing tower, which comprises a drainage pipe, an exhaust pipe and a drainage vacuum cover, wherein the exhaust pipe is arranged above the drainage pipe, the top of the drainage vacuum cover is sealed and is arranged above the exhaust pipe, the bottom of the drainage vacuum cover is arranged below the drainage pipe, air can exist between the drainage vacuum cover and the drainage pipe, and the exhaust pipe is arranged to exhaust, so that the internal and external pressures of the drainage pipe are balanced, and normal water outlet is ensured; in addition, the bottom of the drain pipe is higher than the bottom of the drainage vacuum cover to form a water sealing effect, so that the situation that smoke escapes from the drain pipe when the spraying amount of the desulfurization tower is low is avoided; the possibility that the sediment blocks the drain pipe is thoroughly eliminated, the phenomenon that smoke escapes from the drain pipe is avoided, the environmental benefit is increased, a flushing pipeline is not required to be additionally installed, the investment and the operating cost are reduced, and the purposes of energy conservation and practicability are achieved.

Description

Vacuum drainage device of desulfurizing tower

Technical Field

The utility model relates to a desulfurizing tower field especially relates to a desulfurizing tower vacuum drainage device.

Background

In the form that the desulfurization system adopts the external circulation of the tower, the slurry in the desulfurization tower is directly discharged into an external circulation tank of the tower through a pipeline, but the following defects exist: 1. the drainage mode is generally that the installation position is close to the bottom of the desulfurization tower, and the sediment is more, so that the drainage pipeline is easy to block; 2. when the spraying amount of the desulfurizing tower is reduced, the flue gas can escape from a drainage pipeline due to large drainage flow; 3. and a washing water pipeline needs to be additionally installed, so that the investment and the operating cost are increased.

SUMMERY OF THE UTILITY MODEL

In order to overcome the defects of the prior art, the utility model provides a vacuum drainage device of a desulfurizing tower.

The utility model provides a technical scheme that its technical problem adopted is:

the utility model provides a desulfurizing tower vacuum drainage device, includes drain pipe, blast pipe, drainage vacuum hood, the blast pipe is installed in the drain pipe top, drainage vacuum hood upper portion slope seals and is located the blast pipe top, drainage vacuum hood lower part is opened and is located the drainage pipe below.

As a preferred item, the drainage vacuum hood is of a semicircular structure.

Additional aspects and advantages of the invention will be set forth in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention.

Drawings

The present invention will be further explained with reference to the drawings and examples.

Fig. 1 is a schematic diagram of the present invention.

Detailed Description

Referring to fig. 1, the vacuum drainage device of the desulfurization tower comprises a drainage pipe 1, an exhaust pipe 2 and a drainage vacuum cover 3, wherein the exhaust pipe 2 is arranged above the drainage pipe 1, the top of the drainage vacuum cover 3 is sealed and arranged above the exhaust pipe 2, the bottom of the drainage vacuum cover is arranged below the drainage pipe 1, and the drainage vacuum cover 3 is of a semicircular structure; air can exist between the drainage vacuum cover 3 and the drainage pipe 1, and the drainage pipe 1 is used for exhausting air by installing the exhaust pipe 2, so that the internal pressure and the external pressure of the drainage pipe 1 are balanced, and normal water outlet is ensured; in addition, the bottom of the drain pipe 1 is higher than the bottom of the drain vacuum cover 3 to form a water seal function, so that the situation that smoke escapes from the drain pipe 1 when the spraying amount of the desulfurization tower is low is avoided; the possibility that the sediment blocks the drain pipe 1 is thoroughly eliminated, the phenomenon that smoke escapes from the drain pipe 1 is avoided, the environmental benefit is increased, a flushing pipeline is not required to be additionally installed, the investment and the operating cost are reduced, and the purposes of energy conservation and practicability are achieved.

According to the above principle, the present invention can also make appropriate changes and modifications to the above embodiments. Therefore, the present invention is not limited to the specific embodiments disclosed and described above, and some modifications and changes to the present invention should fall within the protection scope of the claims of the present invention.
