Inner inserting type gas-liquid mixing spray pipe device

Abstract

The invention discloses an inner inserting type gas-liquid mixing spray pipe device, which comprises an inner pipe, wherein the two ends of the inner pipe are respectively provided with a one-way spray head and a gas inlet mechanism; the one-way spray head comprises a valve seat connected with the inner pipe; the air inlet mechanism comprises a mixing chamber communicated with the inner pipe and aplurality of air inlet pipes communicated with the mixing chamber; one end, far away from the inner pipe, of the air inlet mechanism is provided with an executing mechanism; the output end of the executing mechanism is connected with a valve rod moving along the axial line direction of the inner pipe; the valve rod passes through the mixing chamber and is arranged in the inner pipe; one end, nearthe valve seat, of the valve rod is provided with a valve core matched with a valve seat spray nozzle; the surface of the valve core is streamline; the outside of the inner pipe is sleeved with an outer pipe. Excellent anti-corrosion and anti-abrasion performance are realized; the inner inserting type gas-liquid mixing spray pipe device can be used under a high-temperature, high-pressure and acidcorrosion working condition for a long time; through the device, gas and liquid can be uniformly mixed and are then conveyed into a container; the device can be automatically turned off and can be automatically regulated according to the gas inlet condition; media in the container can be effectively prevented from entering the inner pipe, so that the inner pipe blockage can be avoided.

Description

technical field [0001] The invention relates to the related technical field of gas-liquid mixing nozzles, in particular to an interpolated gas-liquid mixing nozzle device. Background technique [0002] At present, in the fields of petrochemical, wastewater treatment and metallurgical smelting, the process reaction needs to be carried out under high temperature and high pressure environment. Under such corrosive and abrasive working conditions, oxygen, steam or other media need to be introduced to participate in the reaction. , so it puts forward very high requirements on the material of the inner pipe and the mixing uniformity of the medium; specifically: [0003] 1. Under the conditions of high temperature, high pressure and corrosive conditions, the process needs to feed gas and steam to react with the medium in the container, and the gas, steam and medium are required to be mixed evenly to improve the reaction speed and effect; but The existing technology cannot mix the ...

Problems solved by technology

[0003] 1. Under the conditions of high temperature, high pressure and corrosive conditions, the process needs to feed gas and steam to react with the medium in the container, and the gas, steam and medium are required to be mixed evenly to improve the reaction speed and effect; but The existing technology cannot mix the gas-solid three-phase medium well, and the reaction effect in the container is very poor

[0004] 2. Part of the process reaction needs to be under high temperature and high acid conditions, and the solution is extremely corrosive, and because the solution contains solid particles, it will also produce greater abrasion during the reaction; under this condition, large Most single metal and non-metal materials cannot be used for a long time

[0005] 3. The solution contains many solid particles, which are very easy to scale; when the gas or steam feeding stops, the solid particles in the solution will enter the inner tube, and will quickly scale until Blockage of the inner tube; in this case, irreversible damage is caused and only a new inner tube can be replaced in the end
