Abstract
The utility model relates to a sour water neutrodyne system, inject pipeline, alkali liquor tube line, nitrogen gas pipeline, fresh water line, vapor line, blowdown pipeline into including the sewage neutralizing tank and with the communicating sewage of sewage neutralizing tank, be equipped with heating coil in the sewage neutralizing tank, heating coil one end and steam pipeline connection, it is outside that the other end stretches out the sewage neutralizing tank to be equipped with the condensate drain valve, still be equipped with the pump in the sewage neutralizing tank, pump and blowdown pipeline connection. The utility model discloses a sour water neutrodyne system is through introducing nitrogen gas pipeline, and it is quick more, even that mixing effect through nitrogen gas makes alkali lye and sewage mix, in having improved and efficiency, in addition, the vapor line can ensure in chilly winter that the neutralizing tank is not influenced by outside temperature, guarantees the continuation and stability of operation.
Description
Technical field
The utility model relates to a kind of sour water neutralising arrangement.
Background technology
In asphalt production process, can produce a large amount of sour waters, as everyone knows, the direct discharge of sour water can cause serious environmental problem, at present general sour water is neutralized after discharge again.Such as, but there is a lot of problem in existing sour water treatment unit, for large-scale treatment unit, only mix with sour water by the injection of alkali lye, often spread, mix uneven, in and speed slow, even there is situation in regional area He not in place; Such as, at northern area, winter time is long, temperature is low, even if sour water treatment unit does isothermal holding, still there is the phenomenon freezed winter.
Summary of the invention
The purpose of this utility model is for the problems referred to above, propose a kind of in and efficiency is higher, adaptability is wider sour water neutralising arrangement.
The purpose of this utility model is achieved in that sour water neutralising arrangement, the sewage comprising sewage neutralizing well and communicate with described sewage neutralizing well injects pipeline, alkali lye pipeline, nitrogen pipeline, vapour line, blowdown pipeline, described nitrogen pipeline, vapour line are equipped with valve, also be provided with pump in described sewage neutralizing well, described pump is connected with blowdown pipeline.
Further, the fresh water pipeline communicated with described sewage neutralizing well is also comprised.
Further, be provided with heating coil in described sewage neutralizing well, described heating coil one end is connected with described vapour line, and it is outside that the other end stretches out described sewage neutralizing well, and be provided with condensate drain valve.
Sour water neutralising arrangement of the present utility model, by introducing nitrogen pipeline, makes alkali lye mix with sewage by the stirring action of nitrogen more quick, even, in improve and efficiency; In addition, in the winter of cold, vapour line can guarantee that neutralizing well does not affect by outside air temperature, ensures persistence and the stability of operation.
Accompanying drawing explanation
Concrete structure of the present utility model is provided by following drawings and Examples:
Fig. 1 is the process flow sheet of sour water neutralising arrangement.
Legend: 1. blowdown pipeline, 2. alkali lye pipeline, 3. nitrogen pipeline, 4. fresh water pipeline, 5. vapour line, 6. sewage injects pipeline, 7. sewage neutralizing well, 8. pump, 9. heating coil, 10. condensate drain valve.
Embodiment
The utility model by the restriction of following embodiment, can not determine concrete embodiment according to the technical solution of the utility model and practical situation.
Embodiment: as shown in Figure 1, sour water neutralising arrangement, the sewage comprising sewage neutralizing well 7 and communicate with sewage neutralizing well 7 injects pipeline 6, alkali lye pipeline 2, nitrogen pipeline 3, fresh water pipeline 4, vapour line 5, blowdown pipeline 1, heating coil 9 is provided with in sewage neutralizing well 7, heating coil 9 one end is connected with vapour line 5, it is outside that the other end stretches out sewage neutralizing well 7, and be provided with condensate drain valve 10; Also be provided with pump 8 in sewage neutralizing well 7, pump 8 is connected with blowdown pipeline 1.
Principle of work of the present utility model is as follows: sour water is from the vapor-liquid separation tank of production plant, injecting pipeline 6 through sewage is disposed in sewage neutralizing well 7, when the sewage level in sewage neutralizing well 7 is to certain altitude, staff samples and assay at the scene on the spot, to detect the pH value height of sewage in sewage neutralizing well 7, the add-on of alkali lye is calculated according to the data results of gained, alkali lye is delivered in sewage neutralizing well 7 by alkali lye pipeline 2, then nitrogen pipeline 3 valve is opened, nitrogen is passed in sewage, under the stirring action of nitrogen, alkali lye and sour water carry out fast, abundant mixing, during dilution to be neutralized about 10 minutes, nitrogen is stopped to pass into, carry out sampling analysis detection again, if pH value is neutral, then hold well blowdown pipeline 1 is delivered to wastewater treatment field pipe network system by ejector priming 8.
In the winter of cold, the easy frozen of the sewage in sewage neutralizing well 7, now, by the valve open on vapour line 5, passes into steam, the sewage temperature in sewage neutralizing well 7 is remained on above freezing in sewage neutralizing well 7.Can also arrange the heating coil 9 be connected with vapour line 5 in sewage neutralizing well 7, improve the heating surface area of sewage, make heating more even, abundant, heating coil 9 can accumulate water of condensation, carries out regular condensate drain by condensate drain valve 10.
If the sour water concentration in sewage neutralizing well 7 is too high, many potential safety hazards can be there is, then by opening the valve on fresh water pipeline 4, in sewage neutralizing well 7, inject fresh water, reducing sour water concentration to safety value.In addition, needing cleaning sullage neutralizing well 7 when meeting checking maintenance, needing equally to utilize fresh water pipeline 4 cleaning sullage neutralizing well 7.
Obviously, above-mentioned explanation of the present utility model is only for the utility model example is clearly described, and is not the restriction to embodiment of the present utility model.Every belong to the technical solution of the utility model the apparent change of amplifying out or variation be still in the row of protection domain of the present utility model.
