In the described fluid reservoir liquid level sensor is installed.
In the assorted machine of described automatic filter liquid level sensor is installed.
On described heat exchanger hot water outlet and the boiler connecting pipe internally piloted valve is installed.
The beneficial effects of the utility model are: by with the exchange heat of hot waste water, low temperature clear water temperature can reach 50-60 ℃, then supplies with dyeing machine and uses, and realizes energy savings, reduces the purpose of cost.
The utility model is described in further detail below in conjunction with drawings and Examples.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Wherein, 1 is that waste water house steward, 2 is that surge tank, 3 is that fluid reservoir, 4 is that filter pump, 5 is that the automatic machine of mixing, 6 of filtering is that exchanging pump, 7 is that sewage water inspection well, 8 is that yarn package dyeing machine, 9 is that hot water house steward, 10 is that heat-exchanger pump, 11 is that boiler, 12 is that internally piloted valve, 13 is that heat exchanger, 14 is the clear water pipe.
The specific embodiment
Such as Fig. 1, a kind of small-sized yarn package dyeing machine waste water residual heat recycle device, comprise yarn package dyeing machine 8, be connected with waste water house steward 1, surge tank 2, filtration system, the heat exchange series hot use system that unifies from the port of export of yarn package dyeing machine 8 in turn, the port of export of hot use system is connected with the entrance point of yarn package dyeing machine 8.
Filtration system comprises successively the fluid reservoir 3 that connects, filter pump 4, the automatically assorted machine 5 of filter and exchanging pump 6, and the entrance point of fluid reservoir 3 is connected with the port of export of surge tank 2, the port of export of exchanging pump 6 and heat-exchange system entrance point be connected.
Heat-exchange system comprises heat exchanger 13, and the hot water inlet end of heat exchanger 13 connects exchanging pump 6, hot water outlet end and connects hot use system, and the cooling water outlet end of heat exchanger 13 connects sewage water inspection well 7, the cooling water inlet end connects clear water pipe 14.
Hot use system comprises boiler 11, heat-exchanger pump 10 and the hot water house steward 9 who connects successively, and the hot water outlet end of heat exchanger 13 is connected with the entrance point of boiler 11, and hot water house steward 9 the port of export is connected with the entrance point of yarn package dyeing machine 8.
Liquid level sensor (be located at fluid reservoir 3 inside, the utility model is sign not) is installed in the fluid reservoir 3.
Liquid level sensor (be located at assorted machine 5 inside of automatic worry, the utility model is sign not) is installed in the assorted machine 5 of filter automatically.
On heat exchanger 13 hot water outlets and boiler 11 connecting pipes internally piloted valve 12 is installed.
The High Temperature High Pressure waste water of yarn package dyeing machine 8 intermittent discharges enters surge tank 2 by waste water house steward 1, after buffering, flow into fluid reservoir 3, when fluid reservoir 3 interior waste water arrive certain liquid level, filter pump 4 starts, carry hot waste water to automatically filtering assorted machine 5, elimination cotton-wool and slurry wherein, by exchanging pump 6 hot waste water is delivered to heat exchanger 13 again, low-temperature wastewater after heat exchange directly enters sewage water inspection well 7, the flow of exchanging pump 6 can be regulated automatically according to waste water liquid level in the assorted machine of automatic filter, and internally piloted valve 12 is opened when exchanging pump 6 starts, the low temperature clear water enters heat exchanger 13 by clear water pipe 14 and carries out exchange heat, high temperature clear water after the exchange flows into boiler 11 by internally piloted valve 12, and the heat-exchanger pump 10 of controlling via constant voltage is delivered to hot water house steward 9, at last for yarn package dyeing machine 8.
The utility model improves dyeing machine technique inflow temperature by to the recycling of yarn package dyeing machine waste water residual heat, reduces the consumption of steam, has realized energy savings, has reduced the purpose of cost.
Above-described embodiment only is used for explaining inventive concept of the present utility model, but not to the restriction of the utility model rights protection, allly utilizes this design that the utility model is carried out the change of unsubstantiality, all should fall into protection domain of the present utility model.
