Description
Technical field
The utility model relates to a kind of direct cooling circulating water system, relates in particular to a kind of direct cooling circulating water system that is applied to weldless steel tube quench cooled field.
Background technology
The weldless steel tube quenching processing technology, after weldless steel tube is heated to certain temperature more than critical temperature and keeps for some time, use direct water coolant that weldless steel tube is carried out cooling rapidly, the metallic molecule structure of weldless steel tube is changed, obtain having at aspects such as intensity, hardness, wear resistance, fatigue strength and toughness the weldless steel tube that significantly improves.
Weldless steel tube quenching technology cooling water generally comprises pipeline and drenches two parts of spray water supply in water supply and pipeline outward, is respectively used to the cooling of processed weldless steel tube outer wall and inwall.Cooling water inflow is with the size variation of product specification, and the surface-area of the inside and outside wall of product is larger, and water consumption is just larger.Usually the cooling outer trickle amount of outer wall is greater than the cooling interior injection flow rate of inwall.Two kinds of cooling waters all are interrupted use with the rhythm of production of weldless steel tube quenching technology, and because rhythm of production is fast, the interruption water time is short, so cooling water supply is the continuous water supply mode.The process-cycle of a weldless steel tube is generally 20 ~ 60 seconds, wherein only 10 ~ 30 seconds water time, accounts for 50%.
According to traditional technique, water supply and treatment system that pipeline drenches spray water in water and pipeline outward adopt dual mode usually:
One, in production process, continuous cooling water is supplied with, and the water coolant through using and being polluted and all be guided to sluice without the water coolant that uses and polluted is processed in treatment system after both mixing, then deliver to the water circulating pump station suction well, recycle.
Two, in production process, the water coolant through using and being polluted is guided to sluice, processes in treatment system, then delivers to the water circulating pump station suction well, recycles.By the recycle-water pipeline, certainly flow back to the water circulating pump station suction well after collecting without the water coolant that uses and polluted, reuse.
Adopt above any mode to supply water, total service discharge is all the nearly twice of actual used water amount, has increased the load of waterworks, makes installed capacity, the floor space of water circulating pump station that larger waste be arranged.And because quantity of circulating water is large, evaporation of water, leakage loss are many, have strengthened the additional water consumption of circulating water system.And adopt first kind of way to supply water, and more increased the load of water treatment system, make the installed capacity of water treatment system, floor space that larger waste also be arranged.
Summary of the invention
The purpose of this utility model is to provide a kind of cooling circulating water system that can effectively reduce the total cooling water inflow of weldless steel tube quenching technology
The concrete technical scheme of a kind of weldless steel tube quench cooled circulating water system of the present utility model is:
A kind of weldless steel tube quench cooled circulating water system, be included as the quenching unit water circulating pump station of outer pouring water coolant be provided, provide for the quenching unit water treatment system of water collecting basin and the water coolant after the processing use of interior spray water coolant, be provided with the pipeline that flows into water collecting basin for untapped outer pouring water coolant in the quenching unit between quenching unit and water collecting basin, be provided with the pipeline that enters water treatment system for the wastewater streams after in the quenching unit between quenching unit and water treatment system, be provided with the pipeline that flows into water circulating pump station for cooling backwater between water treatment system and water circulating pump station.
Further, be provided with the pipeline that enters water treatment system for the water overflow more than needed in water collecting basin between water collecting basin and water treatment system.
Further, the lift pump that promising quenching press group provides interior spray water coolant is set in water collecting basin.
the utility model improves for traditional direct cooling circulating water system of weldless steel tube quenching, in quenching direct cooling circulating water system, adopts in weldless steel tube the mode of co-supplying, the quenching technology rest periods is collected near quenching apparatus water collecting basin without the outer pouring water coolant that uses, when moving, quenching technology resupplies the cooling use of interior spray with force (forcing) pump, thereby reduced the total direct cooling water circulation amount of quenching technology, be conducive to reduce the scale of direct cooling water system and treatment system, reduce cost and occupation of land, can also save simultaneously the additional water of direct cooling water system, reduce production costs.
