Description
Technical Field
the utility model relates to a waste water treatment technical field of steam power plant specifically is a waste water recovery unit of steam power plant.
Background
At present, in a thermal power plant desulfurization system, slurry shunted by a cyclone and weakly acidic wastewater discharged by a vacuum belt dehydrator A/B enter a recovery water tank, one part of the slurry in the recovery water tank enters a desulfurization tower, and the other part of the slurry is subjected to sewage treatment, so that sludge precipitation in a sewage treatment tank is difficult to clean due to the fact that the slurry in the slurry contains too much sludge.
The process flow directly mixes clean wastewater with wastewater containing much mud, and the redundant part exceeding the existing recovery water tank is directly pumped to sewage treatment by a pump, and the sewage treatment needs frequent sludge cleaning.
SUMMERY OF THE UTILITY MODEL
Technical problem to be solved
The utility model provides a to prior art not enough, the utility model provides a waste water recovery unit of steam power plant has solved the process flow and has directly mixed clean waste water with the waste water that contains that mud is many, and unnecessary part that surpasss current recovery tank directly beats sewage treatment with the pump, and sewage treatment needs the problem of frequent clearance mud.
(II) technical scheme
In order to achieve the above purpose, the utility model discloses a following technical scheme realizes: the utility model provides a waste water recovery unit of steam power plant, includes swirler and vacuum belt hydroextractor, the output intercommunication of swirler has recovery tank, recovery tank's output intercommunication has the desulfurizing tower, the output and the vacuum belt hydroextractor intercommunication of desulfurizing tower, vacuum belt hydroextractor's output has the sewage treatment pond through the sour water delivery pump intercommunication.
Preferably, the recovery tank always contains water therein.
Preferably, the inlet height of the recovery water tank is 400mm from the bottom of the tank, and the inlet pipe is inserted 300mm under the liquid.
Preferably, the vacuum belt dehydrator has an internal pressure of 30 kpa.
(III) advantageous effects
The utility model provides a waste water recovery unit of steam power plant. The method has the following beneficial effects:
This waste water recovery unit of steam power plant retrieves sewage treatment alone through the cleaner acid waste water that gets off the vacuum belt feeder, and the thick liquid in the recovery tank advances the desulfurizing tower, and mud all passes through vacuum belt hydroextractor circulation treatment, does so and has reduced the clearance cycle of sewage treatment mud, new recovery tank as long as can satisfy the vacuum requirement can, it is little to have reached the investment, the cost of enterprises has been reduced, the purpose of the frequent clearance mud in the effluent water sump in workshop has been solved simultaneously.
Drawings
FIG. 1 is a flow chart of wastewater recovery according to the present invention.
In the figure: 1 swirler, 2 vacuum belt hydroextractor, 3 recovery water tank, 4 desulfurizing tower, 5 sour water delivery pump, 6 sewage treatment ponds.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1-1, the present invention provides a technical solution: the utility model provides a waste water recovery unit of steam power plant, includes swirler 1 and vacuum belt hydroextractor 2, and swirler 1's output intercommunication has recovery tank 3, and recovery tank 3's output intercommunication has desulfurizing tower 4, and desulfurizing tower 4's output and vacuum belt hydroextractor 2 intercommunication, vacuum belt hydroextractor 2's output have sewage treatment tank 6 through 5 intercommunications of sour water delivery pump. The inside of the recovery water tank 3 always contains water. The inlet height of the recovery water tank 3 is 400mm from the bottom of the tank and the inlet pipe is inserted 300mm below the liquid. The internal pressure of the vacuum belt dehydrator 2 was 30 kpa.
When the device is used, cleaner acidic wastewater discharged from the vacuum belt conveyor 2 is separately recycled and pumped into the sewage treatment tank 6, slurry in the recovery water tank 3 enters the desulfurizing tower 4, and sludge is circularly treated by the vacuum belt dehydrator 2, so that the cleaning period of the slurry for sewage treatment is shortened, the new recovery water tank 3 only needs to meet the requirement of vacuum degree, the investment is not large, and the enterprise cost is reduced; because the space of the thermal power plant is limited, a newly-added water tank for recovering the effluent of the vacuum belt dehydrator 2 is arranged on an accident slurry pool, and an acid water delivery pump 5 is arranged on the ground to pump the part of the water to a wastewater treatment system; the pressure in the gas-liquid separator is 30kpa, and in order to ensure the pressure in the system, the water content in the recovery water tank 3 must be ensured, so the height of a pump inlet of the water tank is 400mm away from the bottom of the tank, and an inlet pipeline is inserted 300mm under the liquid.
It is noted that, herein, relational terms such as first and second, and the like may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Also, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation. The use of the phrase "comprising one of the elements does not exclude the presence of other like elements in the process, method, article, or apparatus that comprises the element.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
