Abstract
The invention relates to sealing of an industrial furnace, in particular to a device and a method for sealing a hole on an industrial furnace body. The flange port plugging device of the industrial furnace body comprises a plastic barrel, the barrel part of the plastic barrel is provided with a flanging, the plastic barrel is inversely buckled on a flange port by the barrel port, and the flanging is bonded and sealed with the flange port. The flange port plugging method of the industrial furnace body comprises the following steps of: finding out connecting equipment of the flange port belonging to non-mechanical sealing on the industrial furnace body; selecting the corresponding plastic barrel and silica gel according to the diameter of the non-mechanically sealed flange port; smearing the silica gel on the bonding face of the flange port; inversely buckling and covering the plastic barrel on the flange port and keeping pressurization for 15-60 minutes; and carrying out an air tightness test by utilizing suds. By adopting a method of plugging the flange por by adopting the plastic barrel (daily article) with the circular-arc flanging and the silica gel tot, the effect of the invention fully satisfies the requirement of the air tightness test, and the invention ensures construction period, reduces engineering cost and ensures that engineering is started on schedule.
Description
Technical field
The present invention relates to the sealing of industrial furnace, relate in particular to port seal and encapsulating method on the industrial furnace body.
Background technique
After the metallurgical equipment industrial furnace is installed back and refractory material and has been built by laying bricks or stones; All to carry out air tightness test to body of heater integral body; To detect the sealability of body of heater under relevant pressure; Its purpose prevents that to reduce the heat loss that coal gas is overflowed and cool air sucks in radiation in the stove, the stove unburnt gas leak problem takes place in the body of heater, guarantees industrial furnace operation back safe operation.
Installed device has nearly 20,000 connection mouths such as furnace roller, radiation pipe, burner, Detecting element, electrical heating elements on the body of heater, they with body of heater on major part be that flange is connected, it is to adopt the mechanical seal form that flange connects majority; Having only electrical heating elements on the body of heater is to reach sealing effect after utilizing body of heater high temperature that the seal ring of electrical heating elements is expanded; Electrical heating elements is generally all about 200 covers on the industrial furnace; Owing to can't seal after installing, if adopt blank flange to carry out shutoff (the flange specification is DN350), then because electrical heating elements length is long; Damaged easily, the ground placement needs reason such as storage rack to cause increasing the air tightness test time and increases engineering cost.
Summary of the invention
The present invention is intended to solve the problems referred to above of background technique, and a kind of industrial furnace body flange mouth blocking device and method for blocking are provided.The present invention carries out shutoff with the method that the Plastic Drum (articles for daily use) of band circular arc flange adds silica gel to flange mouth, and its effect satisfies the requirement of air tightness test fully, has guaranteed the duration, has reduced engineering cost, has guaranteed that engineering goes into operation on schedule.
The present invention is achieved in that
A kind of industrial furnace body flange mouth blocking device, it comprises Plastic Drum, said Plastic Drum bung has flange, and is bonded and sealed with the bung back-off and at flange mouth and with flange mouth.
Described industrial furnace body flange mouth blocking device, the bore of said Plastic Drum is more than or equal to its sealed flange port diameter.
Described industrial furnace body flange mouth blocking device, said Plastic Drum bung and flange mouth are bonded and sealed with silica gel.
The method for blocking of described industrial furnace body flange mouth, it comprises the following steps:
1) finds out the connection device that belongs to on-mechanical formula sealed flange port on the industrial furnace body;
2) the diameter choosing according to the on-mechanical sealed flange port is equipped with corresponding plastic barrel and silica gel;
3) on the adhesive surface of flange mouth, be coated with and spread silica gel;
4) cover the Plastic Drum back-off on the flange mouth, and keep pressurization 15-60 minute;
5) utilize soap solution to carry out bubble-tight test.
The method for blocking of described industrial furnace body flange mouth, said 4) in Plastic Drum applied the pressure of 3kg-5kg.
The method for blocking of described industrial furnace body flange mouth, said 4) in, Plastic Drum is exerted pressure through on Plastic Drum, placing the weight realization.
The present invention adopts Plastic Drum that flange mouth is carried out the time that the industrial furnace gas tightness test has been shortened in shutoff; Lowered engineering cost; Simple to operate, good sealing effect; Buying easily on the material market of selecting for use; Started the shortest record of industrial furnace gas tightness test; In engineering practice, obtained good application.
