Technical field
The present invention relates to the technical field that condensed water is processed, a kind of Coal Chemical Industry full factory condensate water processing system specifically is applicable to mainly that full factory water of condensation is processed and the processing of methane water of condensation, particularly its system's syndeton.
Background technology
Along with the continuous minimizing of prospective oil, and coal reserves accounts for 95% of China's energy total reserves, and therefore increasing Coal Chemical Engineering Project begins build or be about to establish in China.The Coal Chemical Engineering Project water consumption is huge, and the kinds of processes system needs a large amount of steam and water coolant, collects at last to be referred to as water of condensation, and these water of condensation have carried the pollutent such as Fe corrosion product, oil, suspended substance and produced a large amount of heat energy in technical process.Because China's Coal Chemical Engineering Project just just rises, the processing technological flow that neither one is unified, caused the phlegma that has to process defective, whole chemical system is caused corrosion, affect the safe operation of equipment, increased the cost of overhaul, also reduced the work-ing life of equipment, also exist energy utilization efficiency not high, the problem that production energy consumption is excessive; Some phlegma treatment schemees arrange unreasonable, have caused the high cost problem of investment and operation.
Summary of the invention
The object of the present invention is to provide a kind of Coal Chemical Industry full factory condensate water processing system, the problem such as solved that the Coal Chemical Industry phlegma is processed the investment that prior art exists or running cost is too high, poor processing effect, energy utilization efficiency are not high.
to achieve these goals, technical scheme of the present invention is: a kind of Coal Chemical Industry full factory condensate water processing system, it comprises the water of condensation suction culvert, it is characterized in that: described water of condensation suction culvert is connected with one-level plate-type heat exchanger feed-water end, the water side of one-level plate-type heat exchanger is connected with secondary plate-type heat exchanger feed-water end, secondary plate-type heat exchanger water side is connected with water of condensation water tank water intake end, water of condensation water tank water side is connected with the feed-water end of back-washable filter by the water of condensation force (forcing) pump, the water side of back-washable filter is connected with the feed-water end of activated charcoal filter, the water side of activated charcoal filter is connected with the feed-water end of preposition cation exchanger, the water side of preposition cation exchanger is connected with the feed-water end of mixed ion exchanger, the water side of mixed ion exchanger is connected with the feed-water end of qualified water of condensation water tank, the water side of qualified water of condensation water tank is circulated to the feed-water end of one-level plate-type heat exchanger by qualified water of condensation water pump.
The invention discloses a kind of Coal Chemical Industry full factory condensate water processing system, the invention has the advantages that: the processing to water of condensation is targeted, reduces investment and running cost, has namely guaranteed system's effluent quality, has reduced again investment and running cost; High for full factory water of condensation and methane condensate temperature, the water of condensation after the employing processing is qualified comes the heat of exchange system water inlet, has namely satisfied the condition of system's operating temperature, has also reclaimed the energy.
Description of drawings
Fig. 1 is that Coal Chemical Industry of the present invention full factory condensate water processing system connects block diagram.
Embodiment
With reference to the accompanying drawings, the present invention further is described.
the present invention is a kind of Coal Chemical Industry full factory condensate water processing system, as shown in fig. 1, it comprises water of condensation suction culvert 1, it is different from prior art and is: described water of condensation suction culvert 1 is connected with one-level plate-type heat exchanger 2 feed-water ends, the water side of one-level plate-type heat exchanger 2 is connected with secondary plate-type heat exchanger 3 feed-water ends, secondary plate-type heat exchanger 3 water sides are connected with water of condensation water tank 4 feed-water ends, water of condensation water tank 4 water sides are connected with the feed-water end of back-washable filter 6 by water of condensation force (forcing) pump 5, the water side of back-washable filter 6 is connected with the feed-water end of activated charcoal filter 7, the water side of activated charcoal filter 7 is connected with the feed-water end of preposition cation exchanger 8, the water side of preposition cation exchanger 8 is connected with the feed-water end of mixed ion exchanger 9, the water side of mixed ion exchanger 9 is connected with the feed-water end of qualified water of condensation water tank 10, the water side of qualified water of condensation water tank 10 is circulated to the feed-water end of one-level plate-type heat exchanger 2 by qualified water of condensation water pump 11.
In the specific implementation, described one-level plate-type heat exchanger 2 is connected with boiler feed 12.
In the specific implementation, an end of described secondary plate-type heat exchanger 3 is that recirculated cooling water comes water lines 13, and an end of secondary plate-type heat exchanger 3 is cooling water return pipeline 14.
The present invention relates to the system that a kind of Coal Chemical Industry phlegma is processed, the main three kinds of water of condensation of Coal Chemical Industry are different due to the water yield, temperature, contaminated degree, therefore with its separate collection, press respectively the different kinds of process flow processing, wherein, the full factory water of condensation water yield is larger, temperature higher (approximately 150 ℃), and the chemical process flow of experience is more, the pollution level that is subject to is also larger, the iron rot product is larger, contains certain oil, and ammonia quantity is also larger; And the methane water of condensation water yield is less, temperature higher (approximately 100 ℃), and water quality is relatively poor, contains certain iron rot product and oil, sometimes also contains the chemical catalyst powder; Full factory's water of condensation and methane condensate temperature are higher, can not directly enter the subsequent technique flow processing, adopt interchanger to lower the temperature, water of condensation after utilizing processing qualified exchanges this part heat as the water coolant of interchanger, and then supply boiler feed, reach the purpose of energy recovery, to reduce the consumption of bunker coal.
