Abstract
The invention belongs to the technical field of medical gauze processing, and particularly relates to a medical gauze bleaching high temperature wastewater waste heat recovery process. The medical gauze bleaching high temperature wastewater waste heat recovery process comprises the following steps: collecting hot wastewater I discharged at a bleaching section and hot wastewater II discharged in temperature rising water washing, collecting to a hot wastewater tank through a special pipeline, opening a control valve #1, enabling the hot wastewater I discharged at the bleaching section and the hot wastewater II discharged in temperature rising to enter the hot wastewater tank, then to enter a heat exchanger through a #4 pump, and to be discharged a cold wastewater tank after the heat is recovered, meanwhile starting the #4 pump, opening control valves #5 and #6, infiltrating cold soft water into the heat exchanger to absorb heat of the hot wastewater, and then discharging into a hot soft water tank. The medical gauze bleaching high temperature wastewater waste heat recovery process has the benefits that the steam use amount is reduced, the cost is reduced, better social benefit is achieved, energy conservation and emission reduction are realized, the hot water heated by recovered waste heat is used for bleaching and hot water rinsing, the bleaching time is shortened, and the production efficiency is improved.
Description
Technical field
The invention belongs to hospital gauze processing technique field, be specifically related to a kind of hospital gauze bleaching hot waste water waste heat reclaiming process.
Background technology
Gauze is the cotton goods that a kind of longitude and latitude is sparse, textile hospital gauze need be processed through bleaching process, textile hospital gauze bleaching process: prewashing-bleaching-washing-neutralization-washing-pH value adjustment, the current equipment using of the same trade does not possess the use of recovery function, the especially heat recovery between 30-90 degree, although bleaching waste heat recovery economic benefit is higher, but invest larger, operation is controlled complicated, so the current same industry is that high temperature is in line substantially, causes energy waste.
Summary of the invention
The present invention is in order to make up the defect of prior art, provide a kind of and used vapour quantity to reach to reduce, reduced cost, used the hot water of waste heat recovery heating for bleaching, hot water washing, shorten bleaching time, the hospital gauze of enhancing productivity bleaching hot waste water waste heat reclaiming process.
The present invention is achieved through the following technical solutions:
A hospital gauze bleaching hot waste water waste heat reclaiming process, comprises following order step: prewashing-bleaching-intensification washing-overflow washing 1-neutralization-overflow washing 2-pH value adjustment-complete and hang the recovery of cylinder-waste water residual heat;
1, prewashing: fill recycle-water normal temperature running after 15 minutes draining to cold wastewater disposal basin;
2, bleaching: fill hot soft water running and feed in raw material: the hydrogen peroxide that uses content 27.5%, in bleaching liquor, the concentration of hydrogen peroxide is 20 grams of every premium on currency content, the sheet alkali that uses content 99%, the concentration of bleaching liquor is 10 grams of every premium on currency content, refining agent 2g/l, dispersant 3g/l, hydrogen peroxide stabilizer 3g/l, be warming up to 120 degree, temperature retention time 50 minutes, be then cooled to 90 degree after draining to thermal wastewater pond;
3, heat up and wash: fill hot soft water normal temperature running to 75 degree, temperature retention time 10 minutes, then draining is to thermal wastewater pond;
4, overflow washing 1: fill after recycle-water water transport turns, continue water-filling, by top Overflow drainage to cold wastewater disposal basin, after 5 minutes, change fill cold soft water and continue to be washed to 15 minutes after by bottom discharge to reuse pool;
5, neutralization: fill cold soft water running and feed in raw material: 7 kilograms of acetic acid, be warming up to temperature 50 degree, be incubated 20 minutes, rear draining is to cold wastewater disposal basin;
6, overflow washing 2: fill after cold soft water running, continue water-filling, by top Overflow drainage, to reuse pool, the draining of turning round after 20 minutes is to reuse pool;
7, pH value adjustment: fill cold soft water running and feed in raw material: after 2 kilograms of normal temperature of acetic acid turn round 20 minutes, draining is to reuse pool;
8, complete and hang cylinder draining;
9, waste water residual heat reclaims: the thermal wastewater of collecting discharge in the thermal wastewater of bleaching section discharge and the washing that heats up, by pipe special, be collected into thermal wastewater pond, open control valve #1, the thermal wastewater of the thermal wastewater of bleaching section discharge, the washing discharge that heats up is entered to thermal wastewater pond, then by #4 pump, enter after heat exchanger reclaims heat and drain into cold wastewater disposal basin, while #4 pump startup, open control valve #5, #6 cold soft water is squeezed into after heat exchanger absorbs thermal wastewater heat and entered hot soft water pond, for bleaching, intensification washing water-filling etc.
The invention has the beneficial effects as follows: a kind of hospital gauze bleaching of the present invention hot waste water waste heat reclaiming process can reduce uses vapour quantity, reduced cost, and there is a good social benefit, energy-saving and emission-reduction, use the hot water of waste heat recovery heating for bleaching, hot water washing, shorten bleaching time, improved production efficiency.
