Description

Hole opening device for flue or reactor

Technical Field

The utility model relates to a chemical industry equipment, concretely relates to trompil device for on flue or the reactor.

Background

The rising of the power and chemical industries, the continuous improvement of the national emission standards of flue gas, the realization of ultra-low emission and zero emission become the trend of industrial development, and various flue gas treatment systems come into play. In operation or maintenance process, equipment need install great manhole and be used for maintaining equipment, and when equipment operated, equipment was inside to be negative pressure or malleation state, and a large amount of manhole door seal not tight can make whole system's the amount of wind that leaks increase, for the cooperation reaches the design condition, and fan power must increase, consumes the energy and has the risk of overload tripping operation again. In addition, when the equipment design condition exceeded 300 ℃, the shell heat preservation thickness was greater than 300mm, and the cotton thickness of traditional heat preservation is 100 mm's manhole door, when the installation, can form the difference in height with equipment heat preservation, and the cotton high unevenness of heat preservation of other wallboards of manhole door installation department relatively had both influenced pleasing to the eye also inconvenient use.

Disclosure of Invention

In order to solve the problem, the utility model provides a sealed trompil that is used for on flue or the reactor inseparable, simple to operate the technical scheme of the utility model:

a kind of tapping device used in flue or reactor, it installs on manhole of flue or reactor, opens or closes the manhole; it comprises a door frame, a door cover and an inner plug; the door frame covers the manhole and is fixedly connected with the flue or the reactor; the door cover is arranged on the door frame; the door cover is opened or closed, and the door cover is opened and closed with the door frame; the inner plug is arranged in the door frame and covers the manhole; closing the door cover, pressing the door cover on the inner plug, and sealing and contacting the inner plug with the flue or the reactor to seal the manhole; and a seal is arranged between the door cover and the door frame, the door cover is closed, and the door cover is in sealing contact with the door frame.

Closing the door cover, pressing the door cover on the inner plug, and sealing and contacting the inner plug with the flue or the reactor to seal the manhole; meanwhile, the door cover is in sealing contact with the door frame, and the manhole is sealed secondarily, so that the air leakage phenomenon can be effectively avoided; the height difference between the inner plug and the door cover after heat preservation is filled by utilizing the thicknesses of the inner plug and the door cover, so that the installation position of the door cover is relatively level and smooth compared with the heat preservation cotton of other wall plates, and the door cover is convenient to use and attractive; the thickness of the door cover is preferably selected according to the thickness of the heat insulation cotton required by the design condition of the fluid in the equipment.

The technical scheme is further improved and refined, and the door frame is connected with a flue or a reactor in a welding mode.

The technical scheme is further improved and refined, and the door cover is hinged on the door frame; the door cover is convenient to open or close.

The technical scheme is further improved and refined, and the inner plug comprises a wall plate and a plurality of annular handles; the annular handles are uniformly distributed on one side of the wall plate; the size of the wall plate is larger than that of the manhole; the wall plate covers the manhole, the door cover is closed, the door cover is pressed on the annular handle, and the wall plate is in sealing contact with the flue or the reactor to close the manhole; the three handles can be used as tools for opening the wall plate during maintenance, and can play a role in enhancing the heat preservation of the manhole because an air layer is formed at the position.

Preferably, the manhole edge and the wall plate edge of the inner plug are respectively retracted by 4mm, and the manhole edge and the wall plate edge of the inner plug are used for preventing fluid in a flue or a reactor from flowing out.

Preferably, the width of the edge of the door frame is respectively expanded by 1.5mm outwards on the basis of the width of the wall plate so as to be convenient for installing the inner plug, the thickness of the door frame is slightly smaller than the sum of the thickness of the inner plug and the thickness of the door cover, and the sum is about 1 ~ 2mm, so that the door cover is used for pressing the inner plug and the wall plate in the flue during installation, and the flue is prevented from air leakage.

The technical scheme is further improved and refined, and a handle is arranged on the door cover; the door cover is convenient to open or close.

The utility model has the advantages of reasonable design, simple structure, secondary sealing, and effective prevention of air leakage from the manhole; the installation position is relatively level and smooth compared with the heat insulation cotton of other wall plates, thereby being convenient to use and beautiful; the heat preservation effect is good.
