Description
Technical field
The invention belongs to coke gas technical field, it is related to recycling the repair method of circulation.
Background technique
The change that primary cooler circulation is recycled in coking produces water circulating pump in use for some time, exists to some extent
The problem of outlet or inlet valve are not closed completely needs to produce change also with the presence of the situation for producing water circulating pump mechanical seal leakage is changed
Water circulating pump is overhauled, and coal gas needs primary cooler cooling, and primary cooler coal gas set temperature has to be lower than 40 DEG C, otherwise
The normal operation of gas-blowing engine can be influenced because temperature is excessively high.If stoppingization produces water circulating pump, cooling circulating water just stops
It only recycles, primary cooler does not work to stop the conveying of coal gas, needs the process of coal gas to would have to stop, causing to delay work
When, increase the time cost of enterprise.So needing to explore a kind of primary cooler is able to maintain certain cooling capacity, keep coal gas basic
Meets the repair method of the needs of subsequent necessary production facility.
Summary of the invention
The purpose of the present invention is guaranteeing the normal conveying of coal gas, realizationization produces the not shut-down (breakdown) mainteance of water circulating pump, proposes one
The repair method of kind primary cooler circulation.
Technical solution of the present invention: a kind of not shut-down (breakdown) mainteance method of coking recycling primary cooler circulation, it is originally cold
Device circulation is divided into upper and lower two sections, and each to have independent upper hose, return pipe by oneself, increasing connects friendship above upper and lower section water supply valve
Upper section upper hose, lower section upper hose are connected to by siphunculus I, traffic pipe I, traffic valve I are installed on traffic pipe I, in traffic valve I
Lower section upper hose side is equipped with water control valve, increases above upper and lower section return pipe back-water valve (BWV) and connects traffic pipe II, traffic pipe II
Upper section return pipe, lower section return pipe are connected to, traffic valve II is installed on traffic pipe II；When not needing shut-down (breakdown) mainteance, traffic
Valve I, traffic valve II are in close state, and upper and lower two sections of upper hose, return pipe keep respective independent operating, when need
When shut-down (breakdown) mainteance lower sectionization being wanted to produce water circulating pump, coal gas conveying capacity is reduced, lower sectionization produces water circulating pump and stops, and closes water supply valve
II, back-water valve (BWV) I opens traffic valve I, traffic valve II, and the cooling water of lower section is provided by the water inlet pipe of upper section at this time, adjusts water
Control valve aperture enters the water of primary cooler lower section to control, and emptying lower sectionization produces circulating water pool, produces recirculated water to lower sectionization
Pump is overhauled, and restores upper and lower two sections of upper hose, the respective independent operating of return pipe after maintenance；It is examined when needing to stop work
When building sectionization production water circulating pump, coal gas conveying capacity is reduced, upper sectionization produces water circulating pump and stops, and closes water supply valve I, back-water valve (BWV)
II, traffic valve I, traffic valve II are opened, the cooling water of upper section is provided by the water inlet pipe of lower section at this time, regulating pondage control valve
Aperture make water shunt a part enter primary cooler upper section, emptying upper sectionization produce circulating water pool, to upper sectionization produce water circulating pump into
Row maintenance, restores upper and lower two sections of upper hose, the respective independent operating of return pipe after maintenance.
The traffic pipe I is the pipe of DN200.
The traffic pipe II is the pipe of DN250.
Beneficial effects of the present invention: recycle circulation can not shut-down (breakdown) mainteance, this method has transformation simple, no
The advantages of influencing production.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of primary cooler cooling circulating water system transformation of the present invention.
Specific embodiment
As shown in Figure 1, a kind of not shut-down (breakdown) mainteance method of coking recycling primary cooler circulation, originally regenerator cycle water
System is divided into upper and lower two sections, and each to have independent upper hose, return pipe by oneself, increasing connects the friendship of DN200 above upper and lower section water supply valve
Upper section upper hose, lower section upper hose are connected to by siphunculus I 1, traffic pipe I 1, traffic valve I 2 are installed on traffic pipe I 1, in traffic valve
The lower section upper hose side of door I 2 is equipped with water control valve 3, increases the friendship for meeting DN250 above upper and lower section return pipe back-water valve (BWV)
Upper section return pipe, lower section return pipe are connected to by siphunculus II 4, traffic pipe II 4, are equipped with traffic valve II 5 on traffic pipe II 4；No
When needing shut-down (breakdown) mainteance, traffic valve I 2, traffic valve II 5 are in close state, and upper and lower two sections of upper hose, return pipe are protected
Hold respective independent operating.
When needing shut-down (breakdown) mainteance lower sectionization to produce water circulating pump, using the coke oven maintenance time, coal gas conveying capacity reduce when
Section, lower sectionization produce water circulating pump and stop, and close water supply valve II 7, back-water valve (BWV) I 8, open traffic valve I 2, traffic valve II 5, this
When lower section cooling water by upper section water inlet pipe provide, 3 aperture of regulating pondage control valve with control enter primary cooler lower section water
Amount, emptying lower sectionization produce circulating water pool, produce water circulating pump to lower sectionization and overhaul, and replacementization produces water circulating pump outlet when necessary
Or inlet valve, mechanical seal, restore upper and lower two sections of upper hose, the respective independent operating of return pipe after maintenance.
When needing shut-down (breakdown) mainteance upper sectionization to produce water circulating pump, using the coke oven maintenance time, coal gas conveying capacity reduce when
Section, upper sectionization produce water circulating pump and stop, and close water supply valve I 6, back-water valve (BWV) II 9, open traffic valve I 2, traffic valve II 5, this
When upper section cooling water by lower section water inlet pipe provide, 3 aperture of regulating pondage control valve make water shunt a part enter just it is cold
