Physical exciter

Abstract

The invention discloses a physical exciter which is a dissolved gas releaser. The physical exciter consists of a water inlet pipe G, a water inlet throttle orifice plate A, a torrent reflection ring C, a reflection exciter B, a fixed bearing socket D, a cover plate E and a peripheral shell F, wherein a throttle orifice 1 is formed in the center of the water inlet throttle orifice plate A; the reflection exciter B is welded on the water inlet throttle orifice plate A and positioned in the center of the torrent reflection ring C; a shoulder is formed at the periphery of the cylindrical table ofthe reflection exciter B; a blind hole reflection and excitation orifice 2 is formed in the center of the concave surface of the cylindrical table; 4-8 excitation slots 3 are uniformly formed outsidethe blind hole reflection and excitation orifice 2 in a radial horizontal radiation manner and directly communicated with the exterior of the shoulder at the periphery of the cylindrical table; the cylindrical table is provided with a cylindrical table handle which is positioned in the fixed bearing socket D; the fixed bearing socket D is welded on the cover plate E; an exciter shell is composed of the water inlet throttle orifice plate A, the cover plate E and the peripheral shell F; and water and air outlet orifices 4 are formed in the lower section of the peripheral shell F. The physical exciter can better release dissolved gas at low water inlet pressure and low dissolving supersaturation.

Description

technical field [0001] The invention relates to a dissolved air releaser, which is a water treatment device. Background technique [0002] Oilfield production is accompanied by a large amount of oil production wastewater, the water volume is generally 5 to 20 times the oil production, and the water must be strictly treated and then injected back into the ground to maintain the oil production power of the formation. The filtering method is not very effective. Now, the improved oil production wastewater treatment process mostly adopts the method of adding chemical coagulation + partial reflux pressurized dissolved air flotation + filtration, the water treatment effect has been improved, but the treatment cost is high, the effect stability is not high, and the separation The mixed chemicals and other impurities in the produced petroleum severely limit the recovery and reuse of precious petroleum resources, and the large amount of waste residue formed by the flocculation of the...

AI Technical Summary

Problems solved by technology

Dissolved air releasers such as TV, TJ, and TS currently used in conventional air flotation processes are suitable for higher dissolved air supersaturation (dissolved air partial pressure is more than twice that of normal temperature and pressure) and higher water inlet pressure ( Generally above 0.25Mpa), for the lower supersaturation of dissolved natural gas in oil production wastewater (the partial pressure of dissolved natural gas in water is only slightly higher than the saturated vapor pressure of the gas at normal temperature and pressure) and lower water pressure (generally 0.8- 2.0Mpa), although the release effect of these dissolved air releasers is somewhat, but the efficiency is not high, and the release effect is not stable
