Description
Technical field
The present invention relates to gas exhaust pipings to add branch pipe method, is specifically that gas exhaust piping is added under a kind of not shutdown status
The method of branch pipe.
Background technology
For added in original gas exhaust piping branch pipe construction method often first by system-down after, then in pipeline
Upper opening, then the branch pipe added is accessed.This way often due to the shutdown of exhaust system so as to cause the temporary of plant produced
Stop influencing daily production.
Invention content
A kind of gas exhaust piping of present invention offer adds branch pipe method, and it is right during adding branch pipe construction operation to ensure that
The stable operation of original system does not have an impact, to ensure production it is uninterrupted, in order to achieve the above object, the present invention use with
Lower technical solution：Its step is：S1, steel pipe scaffold platform is set up under main air hose；S2, the place for adding branch pipe is being needed to take
If confined space, temporary power wire, respirator pipeline, preparation tool are introduced after the completion of setting up；S3, it is open to main pipeline, in master
Branch pipe is installed at pipeline tapping；S4, connection are completed, and confined space is removed.
Preferably, in S2, confined space is double layer sandwich color steel room, and practical steel pipe and fastener inside confined space
It is reinforced.
Preferably, in S2, after introducing power cord, respirator pipeline, first use infusion and silica gel will be at confined space lead
It is sealed, reuses PVC tape and carry out secondary seal.
Preferably, in the S3, after being open to main pipeline, Ma Kou is fixed to opening using self-tapping screw.
Preferably, in S3, before branch pipe installation, air-valve is remained off and is linked on branch pipe Ma Kou.
Preferably, in S4, the dismountable confined space of ability after sealing effect is confirmed after the completion of branch connection.
Beneficial effects of the present invention：The present invention is needing to add setting confined space at branch pipe position, in confined space
Carry out the trepanning of main air hose, branch pipe is set up, carry out operation in confined space, after pipeline opening, exhaust gas can not reveal or
Person reveals less as far as possible, and adding for pipeline can be completed without shutting down；And confined space be arranged inside board house steel pipe reinforce from
And ensure that the structural strength in temporary airtight space is both simple secured, and it is easy to disassemble, the relatively low dismounting of cost is convenient；To ensure work
Make the safety of personnel, be equipped with biochemical defence suit, breathing apparatus etc., while increasing form on confined space, keeps the people of outside real
When observation confined space in operating personnel real-time status, so that it is guaranteed that the safety of operating personnel.
Description of the drawings
Fig. 1 is that the present invention adds the status diagram before branch pipe；
Fig. 2 is that the present invention adds the status diagram after branch pipe；
Fig. 3 is the structural schematic diagram of the confined space of present patent application；
In figure：1, main air hose；2, confined space；3, branch pipe；4, air-valve；5, form；6, steel pipe scaffold platform；7, branch pipe position
It sets.
Specific implementation mode
The present invention provides pipeline branch is added under a kind of not shutdown status, branch pipe S1, is set up as needed
Steel pipe scaffold platform is set up in position under main air hose；S2, to need the place for adding branch pipe to set up as shown in Figure 3 closed
Space carries out operation in confined space, to ensure that exhaust gas is not revealed or leakage as few as possible, the plane of confined space are big
It is small rational allocation to be carried out according to the size for setting up condition and manifold size at scene, to meet the Job Operations demand of personnel
Subject to, cause confined space to be inhaled flat, confined space choosing by negative pressure to avoid will produce after main air hose trepanning negative pressure in confined space
With double layer sandwich color steel room, and practical steel pipe and fastener are reinforced inside confined space, are reinforced in this way, not only simply but also firm
Gu and it is easy to disassemble, cost is relatively low；To allow the people of outside to observe the real-time status of operating personnel in confined space in real time,
Ensure that the safety of operating personnel, confined space are also provided with observation window, form uses organic transparent glass, strength of glass to need
Meet the suction function of air hose, the specific location of form is subject to the people's observation met outside space；It is introduced after the completion of setting up interim
Power cord, respirator pipeline introduce power cord, prepare hand-hold shearing unit, power drill, self-tapping screw, prefabricated air hose horse
Mouth and the tools such as identical manual adjusting air valve with branch pipe aperture；After respirator pipeline, first use infusion and silica gel by confined air
Between be sealed at lead, reuse PVC tape and carry out secondary seal；S3, it is open to main pipeline using hand-hold shearing unit, profit
Ma Kou is fixed to opening with self-tapping screw and carries out sealing, status diagram as shown in Figure 1 is obtained, then will be ready for
Good air-valve, which remains off, to be linked on branch pipe Ma Kou, is confirmed all simultaneously good seals that are connected firmly, is open in main pipeline
Place's installation branch pipe；As shown in Fig. 2, S4, connection are completed, and confirm the dismountable confined space of ability after sealing effect, confined air is removed
Between, bye-pass is waited for all after the completion of connection, and when having exhaust demand, air-valve below Ma Kou before we open.
Preferably, to ensure the safety of operation, two intercoms are also equipped with, the contact inside and outside guarantee confined space is close
It closes and enters four people in space, dressed personal protective equipment, respirator etc., if the gas in pipeline has the corrosion such as soda acid
Property, it is also necessary to biochemical defence suit is put on, wherein three people carry out operation, a people waits for people with merging with outside through intercom holding unicom
After member enters, confirm that personnel's respirator works normally, the materials such as tool and branch pipe Ma Kou, air-valve, bolt are neat in confined space
Quan Hou, the door for shutting confined space start operation.
