Abstract
A self-cleaning type sand settling filter is applied to oilfield sewage filtering treatment and mainly consists of a filtering screen, a filter main tank and a sand storage tank. A tank top is fixed at the top of the filter main tank, and a water inlet is fixed on a side wall of the filter main tank. The self-cleaning type sand settling filter is characterized in that the filter screen is fixed on the upper portion in the filter main tank, and a water outlet is fixed on the tank top at the top of the filter main tank. The closed sand storage tank is connected to the lower portion of the filter main tank, and a sand discharge opening is fixed on a side wall of the sand storage tank. The self-cleaning type sand settling filter has the advantages that the filter can realize sewage filtering treatment, and filtered sand can settle automatically without blocking the filter. In addition, the self-cleaning type sand settling filter can reduce manual filter screen cleaning, and is convenient in operation and low in manufacturing cost.
Description
Technical field
The utility model relates to the oil-gas field surface engineering technical field, and particularly disposing polluted water in oil is a kind of self-cleaning sand setting filter that oil gas field is produced produced-water reinjection that is used for.
Background technology
At present, in the oil gas field production process, need to handle, because environmental requirement can not be discharged arbitrarily, can only solve effluent problem simultaneously by the mode on produced-water reinjection stratum owing to produce a large amount of sewage.In the produced-water reinjection process, owing to have sand and crystallization etc. in the sewage, often cause that filter screen is blocked, need the frequent clean filter screen, not only time-consuming, and influence normal re-injection effect, stop up the stratum.
The utility model content
The purpose of this utility model is: a kind of self-cleaning sand setting filter is provided, can realizes existing in the sewage sand and crystallization to be filtered and separate, and filter screen can be realized automated cleaning, the artificial filter screen that cleans of minimizing.
The technical solution adopted in the utility model is: the self-cleaning sand setting filter, mainly form by screen pack, filter master jar and sand tank, be fixed with tank deck (end socket) at the top of filter master jar, on the sidewall of filter master jar, be fixed with water inlet, it is characterized in that: the screen pack in that filter master jar internal upper part is fixed with is fixed with delivery port on the tank deck of filter master tank top.Bottom at filter master jar is connected with airtight sand tank, is fixed with sand removing hole on the sidewall of sand tank.
Be connected with valve on described water inlet, delivery port and the sand removing hole.
Described filter master jar is the cylinder jar, and the bottom of filter master tank is an infundibulate.
Described water inlet is oblique following being fixed on the sidewall of filter master jar.
The operation principle of summary self-cleaning sand setting filter: consult Fig. 1.Screen pack 3 is installed in water inlet 1 top and below delivery port.After containing sand sewage and entering from water inlet 1, in filter master jar 4, produce the water sand separation, the part sand sinks to sand tank 5, also have the part sand under the drive of liquid, to move upward simultaneously, when the screen pack 3 because sand can not be blocked the bottom at screen pack 3 by screen pack 3, sink in the sand tank 5 after the sand accumulation on the screen pack 3, the automatic sinking of the sand that filters out can blocking filter.Liquid then moves upward by delivery port 2 by screen pack 3 smoothly, thereby the water that guarantees output is the qualified water that does not contain sand, and the sand in the sand tank will regularly be discharged by sand removing hole 6.Screen pack 3 is made material can adopt stainless steel, carbon steel etc.End socket adopts bolt to be connected with main body.
The beneficial effects of the utility model: the utility model self-cleaning sand setting filter, can realize the sewage water filtration processing, the automatic sinking of the sand that filters out can blocking filter.Can reduce the artificial filter screen that cleans, easy to operate, with low cost.
Description of drawings
Fig. 1 is the utility model self-cleaning sand setting filter structure schematic representation.
Among the figure, 1. water inlet, 2. delivery port, 3. screen pack, 4. filter master jar, 5. sand tank, 6. sand removing hole.
The specific embodiment
Embodiment 1: with a self-cleaning sand setting filter is example, and the utility model is described in further detail.
Consult Fig. 1.The utility model self-cleaning sand setting filter mainly is made up of screen pack 3, filter master jar 4 and sand tank 5.Filter master jar 4 is the cylinder jar, and steel plate is welded into, and the bottom of filter master jar 4 tank bodies is infundibulates.Be fixed with a sphere shape tank deck (end socket) at the top of filter master jar 4, on the sidewall of filter master jar 4, be welded with a water inlet 1 (water pipe), water inlet 1 is oblique following being weldingly fixed on the sidewall of filter master jar 4, is connected with a valve on the water inlet 1.The screen pack 3 that the stainless steel wire that is fixed with at filter master jar 4 internal upper parts weaves.On the tank deck at filter master jar 4 tops, be fixed with a delivery port 2 (water pipe), be connected with a valve on the delivery port 2.Bottom at filter master jar 4 is connected with an airtight sand tank 5 by flange.On the sidewall of sand tank 5, be fixed with sand removing hole 6 (water pipe), be connected with a valve on the sand removing hole 6.
