Vapour, steam heat, which is conducted to dryer surface, is thermally dried wet web, and generally there are two types of approach for steam offer, first, paper plant
Using providing boiler for producing steam for oneself, second is that using steam power plant's steam, the condensed water that is formed after steam heat release by drying cylinder inside
Siphon pipe is discharged, and drying cylinder condensate temperature is generally up to 60 DEG C~80 DEG C, great recycling value.
For using for the paper plant for providing boiler steam supply for oneself, it generally will be used further to boiler water supply after drying cylinder condensation water collection and reach
To the purpose for recycling this part hot water, the condensed water come out from paper machine room enters hot water storage pond by condensed water outlet pipe,
Hot water is sent to boiler feed water storage pool by heat-exchanger pump and recycles when reaching certain liquid level.And for using steam power plant's steam
For paper mill, since transfer pipeline is longer, it is difficult to condensed water is sent back to steam power plant's use again, therefore it is suitable to find other
Utilization ways, this part, thermal water utilization gets up.
Utility model content
Structure optimization need to be carried out to a kind of paper machine room condensation water recovery and use system, for the prior art to provide one
Kind paper machine room condensation water recovery and use system.
The technical solution adopted in the utility model is：
A kind of paper machine room condensation water recovery and use system, including condensate pipe, water-purifying tank and hot-tub, water-purifying tank top
For tubular structure, lower part is pyramidal structure, and condensate pipe is connect with the lower part of water-purifying tank tubular structure, water-purifying tank tubular structure
Top is equipped with hot water outlet, and hot water outlet is connect through hot-water line with hot-tub, and the hot-tub bosom is divided by partition wall
The hot-tub of two overflows connection, wherein the outlet at bottom of the first hot-tub is sent through high-pressure hydraulic pump and high pressure water pump outlet pipe to making
Paper woollen blanket cleans workshop；The outlet at bottom of second hot-tub is pumped to slip house through heat-exchanger pump and hot water water pump outlet pipe.
Further, the center line of condensate pipe outlet with water-purifying tank tubular structure tangential direction, condensate pipe with
The inner cavity of water-purifying tank tubular structure lower part is connected to.
Further, the bottom of the water-purifying tank pyramidal structure is equipped with blow-off pipe, and blow-off pipe is equipped with blowdown valve.
Further, it is equipped with valve on each section of pipeline.
The utility model technical pattern is simple, effectively can carry out separation of removing contamination to condensed water by the way that water-purifying tank is arranged, condense
Water warfare rear portion cleans felt for heat water-spraying, greatly improves felt greasiness removal rate and cleaning efficiency,
Remaining hot condensed water sends to slip house for hot water pulping or deinking, accelerates the softening of paper pulp fiber and profit to rise, to carry
High pulping efficiency improves refining pulp quality, effectively can reasonably be recycled condensed water.
