Example Embodiment

[0032] The present invention will be further described below in conjunction with the accompanying drawings. The examples listed below only represent one or several best embodiments and should not constitute a limitation to the present invention.

[0033] Such as figure 1 Said, the printing and dyeing wastewater heat recovery device provided by the present invention includes: sequentially connected

[0034] Centrifugal filter 1 that uses the high-speed rotation of the water stream to remove impurities with a specific gravity greater than water in the wastewater,

[0035] The first filter 2 and the second filter 3 for further filtering impurities in the waste water,

[0036] The heat exchange system 4 that transfers the heat of the waste water to the clean water.

[0037] The centrifugal filter 1 is provided with a centrifugal separation bin 11 and an impurity collection bin 12. The centrifugal separation bin 11 is located above the impurity collection bin 12, and the centrifugal separat...

Abstract

The invention provides a dyeing wastewater heat recovery device, relating to the technical field of heat recovery. The dyeing wastewater heat recovery device comprises a centrifugal filter, a first filter, a second filter and a heat exchange system, wherein the first filter and second filter are connected in parallel; the centrifugal filter is respectively communicated with a high-temperature wastewater tank, a low-temperature wastewater tank, the first filter and the second filter; and the heat exchange system is respectively communicated with a high-temperature clean water tank, a low-temperature clean water tank, the first filter and the second filter. The dyeing wastewater heat recovery device provided by the invention has high heat exchange efficiency, has the function of automatic backflush and cleaning, can effectively prevent scales from generation, and does not need attended operation in the working process.

Description

technical field [0001] The invention relates to the technical field of heat energy recovery, in particular to a heat energy recovery device for printing and dyeing wastewater. Background technique [0002] At present, under the excellent situation that the country is vigorously promoting the "energy saving and emission reduction" plan, the development and research of some energy-saving equipment are continuously carried out, especially for the recovery and reuse of heat energy in the hot wastewater discharged from factories and buildings. However, heat exchangers and heat exchange equipment commonly used in China for waste heat recovery can produce obvious economic and environmental benefits in theory, but the removal of large particles and suspended impurities in wastewater, the reasonable selection of filters, and the use of filters and heat exchange Technical problems such as unit blockage and pollution have yet to be found for better solutions.
