Abstract
Description
Technical field:
[0001] The utility model relates to the technical field of petrochemical industry, in particular to a concrete drainage liquid discharge spray tank. Background technology:
[0002] The petrochemical industry is increasingly developing in the direction of large-scale, high efficiency, safety and environmental protection. The treatment and storage of flowback fluid is particularly important. At present, the traditional way to treat flowback fluid is generally to burn it in a steel spray tank. Due to the strong corrosiveness of the flowback fluid, it cannot be stored for a long time in the traditional steel spray tank. Therefore, after the flowback fluid accumulates to a certain level, it is necessary to shut down the well, pour the liquid, and transport it, and so on. At present, the traditional ways to store flowback fluid include concrete cement pools, polygonal steel splicing liquid storage tanks, etc. Concrete cement pools are expensive, cannot be reused, and are difficult to reclaim after use; the polygonal steel splicing liquid storage tanks that have emerged in recent years have met the large-scale and high-efficiency storage needs to a certain extent, but when facing the long-term storage of highly acidic and alkaline corrosive liquids, once the internal anti-seepage layer is chemically corroded or physically damaged, the highly corrosive liquid will penetrate the anti-seepage layer and slowly corrode the steel, causing leakage risks. Utility model content:
[0003] The technical problem to be solved by the utility model is to provide a concrete return liquid discharge spray tank, which can be used individually or in series to form a tank group according to actual needs. It can not only continuously process the return liquid, improve efficiency and save costs, but also store the return liquid for a long time, can be used repeatedly, has good long-term acid and alkali resistance, and is convenient for transportation.
[0004] The technical scheme adopted by the utility model is: a concrete return liquid discharge spray tank, comprising a tank body; the tank body is made of reinforced concrete as a whole, the inner and outer surfaces of the tank body are treated with anti-corrosion as a whole, and the base of the tank body is penetrated by a steel pipe as a lifting lug; a discharge flange port that can be connected to a wellhead discharge pipe line is arranged in front of the tank body, a detachable discharge pipe connected to the discharge flange port is arranged in the tank body, and reinforced concrete partitions I and II whose heights are lower than the height of the tank body are arranged in sequence inside the tank body from front to back, and the height of reinforced concrete partition I is higher than that of reinforced concrete partition II, and filter screen windows I and filter screen windows II are respectively arranged on reinforced concrete partition I and reinforced concrete partition II, and the inside of the tank body is divided into storage bins I, II and III from front to back by reinforced concrete partition I and reinforced concrete partition II, a fireproof cover is arranged on the tank body at the top of storage bin I, and connecting flange ports are respectively arranged on the tank body on both sides of storage bin III.
[0005] Furthermore, the number of the steel pipes is 2, the steel pipes are arranged parallel to the width of the tank body, and the 2 steel pipes are arranged at equal distances on the base of the tank body.
[0006] Furthermore, the filter mesh of the filter window I is larger than the filter mesh of the filter window II.
[0007] Furthermore, the fireproof cover is a reinforced concrete fireproof cover.
[0008] Furthermore, the anti-corrosion treatment is to spray an anti-corrosion coating on the inner and outer surfaces of the tank body, and the anti-corrosion coating uses 2 coats of epoxy zinc-rich primer, 1 coat of epoxy micaceous iron intermediate paint, and 3 coats of polyurethane topcoat.
[0009] The beneficial effects of the utility model are as follows: the device can be used alone or in series to form a tank group according to actual needs. The device can not only continuously process the return liquid, achieve high efficiency and save costs, but also store the return liquid for a long time, can be used repeatedly, has good long-term acid and alkali resistance, and is convenient for transportation. Description of the drawings:
[0010] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0012] Figure 2 It is a top view of the utility model.
[0013] Figure 3 It is a schematic diagram of the structure of the front side of the utility model. Specific implementation method:
[0014] like Figure 1 , Figure 2 , Figure 3 As shown, a concrete return liquid discharge spray tank includes a tank body; the tank body is made of reinforced concrete, and the inner and outer surfaces of the tank body are treated with anti-corrosion. The tank body has a capacity of 50m 3 , specifications (length * width * height) 9*2.5*2.5m, base 1 thickness 200mm, tank body wall thickness 150mm, the base 1 of the tank body is penetrated by a steel pipe 6 as a lifting lug; two blowout flanges that can be connected to the wellhead blowout pipe line are arranged in front of the tank body, and a detachable blowout pipe 8 connected to the blowout flange is arranged in the tank body.
[0015] From front to back, reinforced concrete partition I2 and reinforced concrete partition II3 are arranged in sequence, with the height lower than the height of the tank. Reinforced concrete partition I2 is arranged 4m away from the front of the tank (width*height), with a height of 2m and a width of 2.5m; reinforced concrete partition II3 is arranged between reinforced concrete partition I2 and the tail of the tank, with a height of 1.5m and a width of 2.5m. Filter screen windows I5 and II4 are arranged on reinforced concrete partition I2 and reinforced concrete partition II3, respectively. The length*width of filter screen windows I5 and II4 is 0.5*0.5m, and the filter mesh of the filter screen window I5 is larger than the filter mesh of the filter screen window II4. The two partitions play the role of sedimentation, filtration, separation of return liquid and strengthening the support of the tank. Reinforced concrete partition I2 and reinforced concrete partition II3 divide the interior of the tank into storage bin I, storage bin II and storage bin III from front to back. Two connecting flanges 9 are arranged on the tanks on both sides of storage bin III, respectively, so that the spray tanks can be connected in series. Storage bin 1 is a sedimentation bin, which is used for the discharge and combustion of the return liquid and the sedimentation of the waste liquid. Storage bin 2 is a filtration bin, which is mainly used to filter the fine particles flowing in from storage bin 1. Storage bin 3 is a storage series bin, which is mainly used to discharge the treated return liquid or connect in series with other concrete return liquid discharge tanks to achieve the purpose of long-term and large-scale treatment and storage of return liquid.
[0016] A reinforced concrete fireproof cover with a length of 1.5m and a width of 2.5m is installed on the tank body at the top of storage bin Ⅰ to prevent damage to surrounding objects due to excessive fire when storage bin 1 explodes and burns.
[0017] There are two steel pipes 6 , which are arranged parallel to the width of the tank body, and the two steel pipes 6 are arranged on the base 1 of the tank body at equal distances.
[0018] The anti-corrosion treatment is to spray an anti-corrosion coating on the inner and outer surfaces of the tank body. The anti-corrosion coating uses 2 coats of epoxy zinc-rich primer, 1 coat of epoxy micaceous iron intermediate paint, and 3 coats of polyurethane topcoat.
