Abstract
The utility model relates to a kind of condensate return device of paper machine, comprise the cylinder group of paper machine, cylinder group comprises some sub-drying cylinders, the output of every sub-drying cylinder all connects to a condenser, the output of each condenser connects to a water pump, each water delivery side of pump connects to a butterfly valve, the unified company to a condensation water tank of output of each butterfly valve, the output of condensation water tank connects to oxygen-eliminating device by a variable frequency pump group, oxygen-eliminating device connects to boiler, the drum of boiler upper end is given every sub-drying cylinder air feed, adopt after above technical scheme: the utility model reclaims the condensed water of drying cylinder to draw back boiler, thereby reduce the consumption of boiler running water, and the temperature of condensed water is far above water temperature from the beginning, so in reducing running water consumption, also reduced boiler fired coal consumption, play the effect of energy-saving and emission-reduction.
Description
Technical field
The utility model belongs to field of papermaking, is specifically related to a kind of condensate return device of paper machine.
Background technology
In manufacture of the prior art field, use water source that can be a large amount of, but when condensed water from drying cylinder out after, conventionally all can slattern, be unfavorable for like this environmental protection.
Summary of the invention
The utility model, in order to solve the technical problem of mentioning in background technology, provides a kind of condensate return device of paper machine.
For solving the problems of the technologies described above, the utility model by the following technical solutions:
A kind of condensate return device of paper machine, comprise paper machine dryer group, paper machine dryer group comprises some sub-paper machine dryers, the output of every sub-paper machine dryer all connects to a condenser, the output of each condenser connects to a water pump, each water delivery side of pump connects to a butterfly valve, the unified company to a condensation water tank of output of each butterfly valve, the output of condensation water tank connects to oxygen-eliminating device by a variable frequency pump group, oxygen-eliminating device connects to boiler, and the drum of boiler upper end is given every sub-paper machine dryer air feed.
Variable frequency pump group comprises two variable frequency pump group branch roads in parallel, and every variable frequency pump group branch road comprises the first dish valve, variable frequency pump and the second dish valve successively, and the output of variable frequency pump group connects to oxygen-eliminating device by time butterfly valve.
Boiler also connects to a chimney by dust-removal cloth-bag.
Adopt after above technical scheme: the utility model reclaims the condensed water of drying cylinder to draw back boiler, thereby reduce the consumption of boiler running water, and the temperature of condensed water is far above water temperature from the beginning, so in reducing running water consumption, also reduce boiler fired coal consumption, played the effect of energy-saving and emission-reduction.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Referring to Fig. 1, a kind of condensate return device of paper machine, comprise paper machine dryer group, paper machine dryer group comprises some sub-paper machine dryers 1, the output of every sub-paper machine dryer 1 all connects to a condenser 2, the output of each condenser 2 connects to a water pump 3, the output of each water pump 3 connects to a butterfly valve 4, the unified company to a condensation water tank 5 of output of each butterfly valve 4, the output of condensation water tank 5 connects to oxygen-eliminating device 6 by a variable frequency pump group, oxygen-eliminating device 6 connects to boiler 7, and the drum 8 of boiler 7 upper ends is given every sub-paper machine dryer 1 air feed.
Explain for all parts of the present utility model:
1) variable frequency pump group comprises two variable frequency pump group branch roads in parallel, and every variable frequency pump group branch road comprises the first dish valve 9, variable frequency pump 10 and the second dish valve 11 successively, and the output of variable frequency pump group connects to oxygen-eliminating device 6 by time butterfly valve 12.
