Description

Waste water heat recovering equipment
Technical field
The utility model relates to a kind of waste water heat recovering equipment, belongs to the thermal recovery unit technical field of structures.
Background technology
In industries such as printing and dyeing, papermaking; All have every day a large amount of hot waste waters to discharge, these wastewater temperatures are higher, and are high more than 85 ℃; Low also about 65 ℃; A large amount of heat energy is along with the discharge of waste water wastes, and the hot waste water of discharging brings a lot of troubles (high temperature can kill active bacterium more than 45 ℃) to sewage disposal system again, increases a lot of costs.On the other hand; With the dyeing is example; Destarch in the printing and dyeing enterprise, boiling-off, bleaching, mercerising after washing section and various rinsing machine are in use; Need constantly to replenish clear water again and be heated to 85-98 ℃, discharge the spent hot water that quantity equates simultaneously, this discharging spent hot water replenishes the technology waste mass energy that cold water heats again again.Facing the production cost that energy supply the caused rising of current growing tension, how to save the energy, reduce cost, is the difficult problem that numerous enterprises is thought deeply always, also becomes to reduce cost today, increases one of inevitable approach of benefit.
Summary of the invention
The purpose of the utility model is to solve the weak point that above-mentioned prior art exists; A kind of reasonable in design is provided, can spent hot water and cold clear water be carried out the waste water heat recovering equipment of exchange heat; It makes, and heat carries out second use in the waste water, with the clear water heating, and waste water cooling simultaneously; The part cycling utilization of wastewater reaches and makes full use of the used heat resource, saves steam, reduces the purpose of cost for wastewater treatment simultaneously.
The utility model is realized through following technical scheme:
Waste water heat recovering equipment, its special character are to comprise dynamic filtration case 1, the static filtering tube 2 that communicates with dynamic filtration case 1, the pipe circle pump 3 that is communicated with the port of export of static filtering tube 2 and the heat exchanger 5 that is used for the hot and cold water exchange heat that is used for first filtration.
Said heat exchanger 5 is a heat-exchangers of the plate type, and the one of which end interface communicates with spent hot water's pipeline 7, and other end contradirectional interface communicates with cold water pipes 8.
Each intake-outlet of said heat-exchangers of the plate type all is equipped with temperature sensor, is used for the indicated temperature situation.
By-pass valve control on said spent hot water's pipeline and the cold water pipes all adopts the air bladder valve.
The course of work of the utility model: the spent hot water introduces the dynamic filtration case through pipeline; Filter the back and flow into water storage box, be transported to heat-exchangers of the plate type through static filtering tube (being secondary filter) by circulating pump, clear water is gone into board-like heat exchanger through the pipeline reverse flow simultaneously; Through after the sufficient heat exchange; Sewage enters sewer, and clear water gets into rinsing machine and does the supplementing water use, or the connection shower is done the shower water use.
The utility model beneficial effect: reasonable in design, adopt multiple automatic fitration, multiple clean and maintenance function, make full use of the used heat resource; Both saved steam, and reduced cost for wastewater treatment again simultaneously, each intake-outlet temperature can directly show; Reclaim heat and calculate automatically, practice thrift cost and show that directly automaticity is high; Must staff on duty, to the industry energy conservation consumption reduction, the protection environment, increase the benefit significant.

Among the figure: 1, dynamic filtration case, 2, the static filtering tube, 3, pipe circle pump, 4, the air bladder valve, 5, heat exchanger, 6, temperature sensor, 7, spent hot water's pipeline, 8, cold water pipes.
The specific embodiment
Following with reference to accompanying drawing, provide the specific embodiment of the utility model, be used for the formation of the utility model is further specified.
Embodiment 1
The waste water heat recovering equipment of present embodiment comprises being used for first dynamic filtration case 1, the static filtering tube 2 that communicates with dynamic filtration case 1, the pipe circle pump 3 that is communicated with the port of export of static filtering tube 2 and the heat-exchangers of the plate type 5 that is used for the hot and cold water exchange heat that filters.
One end interface of heat-exchangers of the plate type 5 communicates with spent hot water's pipeline 7, and other end contradirectional interface communicates with cold water pipes 8.The plate-type heat-exchange sheet is smooth and thin, is difficult for generating dirt, and higher heat transfer coefficient is arranged.
Each intake-outlet of heat-exchangers of the plate type all is equipped with temperature sensor, is used for the indicated temperature situation.
By-pass valve control on spent hot water's pipeline and the cold water pipes all adopts the air bladder valve.
The course of work of the utility model: the spent hot water introduces the dynamic filtration case through pipeline; Filter the back and flow into water storage box, be transported to heat-exchangers of the plate type through static filtering tube (being secondary filter) by circulating pump, clear water is gone into board-like heat exchanger through the pipeline reverse flow simultaneously; Through after the sufficient heat exchange; Sewage enters sewer, and clear water gets into rinsing machine and does the supplementing water use, or the connection shower is done the shower water use.
For example, 90-95 ℃ of this device spent hot water inflow temperature, leaving water temperature can be reduced to 25-35 ℃, 15 ℃ of clear water inflow temperatures, leaving water temperature can be up to 78-83 ℃.And old tubular type (coil pipe, tubulation, fourth pipe) structure is owing to be prone to generate dirt, and heat transfer efficiency is low, 90-95 ℃ of sewage inflow temperature, and 52 ℃ of leaving water temperatures, 15 ℃ of clear water inflow temperatures, leaving water temperature have only 56 ℃.And owing to after reasons such as pipeline structure use 1 month, leaving water temperature will drop to about 50 ℃.And for once filter, after sewage need enter cesspool or foul water tank, advance heat-exchange system again, floor space is big, easy blocking.
Energy-conservation value is example with dyeing after washing machine, mercerising rinsing machine, various rinsing machine: the washing section amount of water is per hour 5 tons, produces every day 12 hours, and is annual by calculating in 300 days, needs to add cold water 5 * 12 * 300=18000 ton/year.
18000 tons of clear water are warming up to 60 ℃, be its heating if use the 0.3Mpa saturated vapor, 1880 tons of need saturated vapors, and cost is per ton presses 180 yuan of calculating, and the totle drilling cost of saturated vapor is 180 yuan/ton * 1880 tons=338400 yuan.And this waste water heat recovering equipment can be heated to 15 ℃ clear water more than 78 ℃, thereby economic benefit is very considerable.
To sum up compare, the utility model has really reached and has made full use of the used heat resource, saves steam, reduces the purpose of cost for wastewater treatment simultaneously.Be current industry energy conservation consumption reduction, protection environment, the inevitable choice of increasing the benefit.
