Abstract
The invention provides a recovery system for waste heat of printing and dyeing wastewater. The recovery system comprises a hot wastewater collecting pool, a filter and a hot water pump, the hot water pump is used for pumping wastewater in the hot wastewater collecting pool to the filter, an output end of the filter is connected with a heat supply medium input end of a plate-type heat exchanger, a heat supply medium output end of the plate-type heat exchanger is connected to a hot wastewater storage pool or a hot wastewater treatment device, and a heat absorption medium output end of the plate-type heat exchanger is connected to a water storage or water consumption device. By modification on a wastewater collecting system, high-temperature wastewater is collected and delivered independently so as to recycle the waste heat of the printing and dyeing wastewater, and the recovery system is energy-saving and environment-friendly.
Description
Technical field
The present invention relates to dyeing waste water waste heat recovery field, be specifically related to a kind of dyeing waste water residual neat recovering system.
Background technology
At present, the environmental problems such as printing and dyeing enterprise water, draining and Treatment of Sludge highlight day by day, and the many dyeings of China developed regions environmental carrying capacity is very limited, and printing and dyeing enterprise will reach that volume increase does not increase dirt or the dirty target that reduces, only have employing energy-conserving and emission-cutting technology, realize cleaner production.And printing and dyeing enterprise is in bleachinging and dyeing the process of washing, boil yarn, float yarn and high temperature washing step and can produce the temperature hot waste water above up to 80 ℃, if directly arrange in people's wastewater equalization pond, can make wastewater temperature in treatment system up to more than 46 ℃, both reduce biochemical treatment efficiency, cause again energy waste, and existing most of enterprise hot waste gas, thermal wastewater directly discharge, equipment is controlled does not have energy saver, and printing and dyeing sludge is not effectively addressed mostly, and the task that industry energy conservation reduces discharging is very arduous.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of dyeing waste water residual neat recovering system, by transformation wastewater collection system, hot waste water is collected separately and is carried to reach dyeing waste water heat recovery, energy-conserving and environment-protective separately.
For solving above-mentioned existing technical problem, the present invention adopts following scheme: dyeing waste water residual neat recovering system, comprise spent hot water's collecting pit, filter and for the waste water in spent hot water's collecting pit being evacuated to the heat-exchanger pump of filter, the output of filter is connected with the heating medium input of plate-type exchanger, the heating medium output of plate-type exchanger is connected to spent hot water's storage pool or spent hot water's treatment facility, and the heat-absorbing medium output of plate-type exchanger is connected to water storage or watering equipment.
As preferably, the waste water import department of spent hot water's collecting pit is provided with for holding back the grid of the thick dirt of waste water.
As preferably, the inwall of spent hot water's collecting pit is provided with heat-insulation layer.
As preferably, the bottom sidepiece of spent hot water's collecting pit is provided with the outlet with shutter door, and outlet realizes switching by shutter door, is provided with scraper plate bottom spent hot water's collecting pit, and scraper plate is by cylinder drive work.
As preferably, the interior diapire of spent hot water's collecting pit is inclined-plane.
Beneficial effect:
The dyeing waste water residual neat recovering system that the present invention adopts technique scheme to provide, by transformation wastewater collection system, collects hot waste water separately and carries to reach dyeing waste water heat recovery, energy-conserving and environment-protective separately.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is the structural representation of spent hot water's collecting pit in the present invention.
The specific embodiment
As illustrated in fig. 1 and 2, dyeing waste water residual neat recovering system, comprise spent hot water's collecting pit 1, filter 2 and for the waste water in spent hot water's collecting pit 1 being evacuated to the heat-exchanger pump 3 of filter 2, the output of filter 2 is connected with the heating medium input of plate-type exchanger 4, the heating medium output of plate-type exchanger 4 is connected to spent hot water's storage pool or spent hot water's treatment facility, and the heat-absorbing medium output of plate-type exchanger 4 is connected to water storage or watering equipment.The waste water import department of spent hot water's collecting pit 1 is provided with for holding back the grid 5 of the thick dirt of waste water.The inwall of spent hot water's collecting pit 1 is provided with heat-insulation layer 6.The bottom sidepiece of spent hot water's collecting pit 1 is provided with the outlet with shutter door 7, and outlet is realized and being opened and closed by shutter door 7, and spent hot water's collecting pit 1 bottom is provided with scraper plate 8, and scraper plate 8 is by cylinder 9 drive work.The interior diapire wall of spent hot water's collecting pit 1 is inclined-plane.
Filter 2 adopts high-intensity wedge shape filter screen, is provided with backwash mechanism (backwash sucker) in filter 2, by pressure reduction control, timing controlled automatic cleaning filter core.In filter, impurity accumulates in cartridge surface and causes that inlet outlet pressure differential increases to setting value, or timer is while reaching preset time, and electric operated control box sends signal, drives backwash mechanism.When backwash sucker mouth and filter core import over against time, blowoff valve is opened, now system decompression draining, sucker and filter core inner side occur that a relative pressure is lower than the negative pressuren zone of the outer side hydraulic pressure of filter core, force the clean recirculated water of part side inflow filter core inner side from filter core, the contaminant particles being adsorbed in filter core Nell wall flows in Rang dish and discharges from blowoff valve with water.Filter screen makes the inner jeting effect that produces of filter core, and any impurity all will be washed away from smooth inwall.When the recovery of filter inlet outlet pressure differential is normal or timer setting-up time finishes, in whole process, material continues to flow, and backwash water consumption is few, has realized serialization, automated production.
The course of work: the hot waste water that dyeing apparatus produces converges to spent hot water's collecting pit 1, by heat-exchanger pump 3, be evacuated to filter 2, after filtering, filter 2 enters plate-type exchanger 4 heat exchange, waste water after heat exchange enters spent hot water's storage pool or spent hot water's treatment facility from heating medium output, and the clear water after heat exchange passes to water storage or watering equipment as boiler, dyeing apparatus etc. after heat absorption heats up.On spent hot water's collecting pit 1, be provided with grid 5, for holding back the thick dirt of waste water; The inwall of spent hot water's collecting pit 1 is provided with heat-insulation layer 6, for insulation, improves heat utilization efficiency.The bottom sidepiece of spent hot water's collecting pit 1 is provided with the outlet with shutter door 7, and outlet is realized and being opened and closed by shutter door 7, and spent hot water's collecting pit 1 bottom is provided with scraper plate 8, and the mud of spent hot water's collecting pit 1 bottom etc. are easily discharged, and scraper plate 8 is convenient to scrape mud makes its discharge.The interior diapire of spent hot water's collecting pit 1 is that mud discharge is convenient on inclined-plane.
