Description

Deicing device for top of steel chimney

Technical Field

The utility model relates to a waste heat boiler technical field specifically is a steel chimney top defroster.

Background

The waste heat boiler generally refers to equipment for recovering waste heat in various process flows to reduce energy consumption, and is a collection of heat exchangers, and can improve the heat efficiency of the whole equipment of a system. The waste heat boiler can improve the overall energy utilization rate of the system, achieve the purpose of saving energy and reduce environmental pollution, so that the waste heat boiler plays a vital role in energy conservation and environmental protection. Different from the traditional coal-fired boiler, the waste heat boiler has no combustion equipment, the flue is in positive pressure during working, the temperature of the flue gas at the inlet of the boiler is generally not high and is generally 650 ℃ or less, and therefore the flow rate of the flue gas is much larger than that of the conventional boiler. In order to ensure the environment-friendly effect, the discharged smoke does not influence the local air quality, and the outlet elevation at the top of the chimney is generally higher. Moisture near the top of the steel chimney is easy to generate condensation and form ice in an extremely high altitude low temperature environment. After the ice is melted into water, the ice is easy to permeate into the heat-insulating layer to cause the corrosion of the wall of the steel chimney.

Disclosure of Invention

In order to solve the problem that current steel chimney section of thick bamboo wall corrodes easily, the utility model provides a steel chimney top defroster, it can prevent effectively that water is downflow along section of thick bamboo wall, the condition of corruption can not appear.

The technical scheme is as follows: the steel chimney top deicing device comprises a steel chimney and is characterized in that a circle of folded plate is welded on the outer peripheral face of the cylinder wall of the steel chimney, the folded plate inclines from outside to inside, a water collecting tank is formed by the folded plate and the outer peripheral face of the cylinder wall of the steel chimney, an elbow is arranged in the steel chimney, a water inlet at one end of the elbow penetrates through the cylinder wall of the steel chimney and is communicated with the water collecting tank, and a water outlet at the other end of the elbow is arranged upwards.

It is further characterized in that the water inlet of the elbow is positioned at the lowest inclined position of the folded plate;

four bent pipes are uniformly arranged;

the return bend includes U-shaped section and segmental arc, segmental arc one end is the water inlet, the other end with the one end of U-shaped section is connected, the U-shaped section other end is the delivery port, the delivery port is less than the water inlet.

Adopt the utility model discloses afterwards, in the water that the steel chimney top melts got into the water catch bowl, not follow section of thick bamboo wall downflow, but the inside return bend of chimney is directly introduced, comes out along with the inside high temperature flue gas evaporation of chimney from the return bend and discharges, the effectual condition that corrodes appears in the steel chimney section of thick bamboo wall that has prevented.

Detailed Description

Referring to fig. 1, 2 and 3, the steel chimney top deicing device comprises a steel chimney 1, wherein a circle of folded plate 2 is welded on the outer circumferential surface of the cylinder wall of the steel chimney 1, the folded plate 2 inclines from outside to inside, a water collecting tank is formed by the folded plate 2 and the outer circumferential surface of the cylinder wall of the steel chimney 1, four bent pipes 3 which are uniformly arranged are arranged in the steel chimney 1, a water inlet at one end of each bent pipe 3 penetrates through the cylinder wall of the steel chimney 1 and is communicated with the water collecting tank, and a water outlet at the other end of each bent pipe 3 is arranged upwards, so that water is.

In order to ensure that the water in the water collecting tank can be smoothly reserved, the water inlet of the bent pipe 3 is positioned at the lowest inclined position of the folded plate 2.

The elbow 3 comprises a U-shaped section 3-1 and an arc-shaped section 3-2, one end of the arc-shaped section 3-2 is a water inlet, the other end is connected with one end of the U-shaped section 3-1, the other end of the U-shaped section 3-1 is a water outlet, and the water outlet is lower than the water inlet.
