Description

Technical Field

[0001] The utility model relates to the technical field of gas-liquid separation, in particular to a gas-liquid separation device. Background Art

[0002] In the treatment of high-salinity wastewater, the recycling of distilled water in various evaporation technologies is very important, especially aeration evaporation and spray evaporation. The evaporated water vapor is in the form of low-temperature steam, bubbles and ultrafine water droplets, which carry water and air. To recycle the evaporated water, it is necessary to separate the gas and water, exhaust the air and collect the condensed water. During the cooling or pressurization process of saturated gas, a part of the condensable gas components will form small droplets and flow with the gas. The function of the gas-liquid separator is to treat gas containing a small amount of condensate to achieve condensate recovery or gas phase purification. Its structure is generally a pressure vessel with related air intake components and droplet capture components inside. When the evaporating gas flow containing bubbles (gas, mist <ultrafine water droplets>, steam) is introduced into the gas-liquid separator, the gas-liquid separator separates the bubbles from the evaporating gas flow through the separation step and separation acceleration, and collects the condensed water and bubbles separately through the collection step. Due to the limited carrying capacity of existing gas-liquid separation devices, with the sharp increase in the amount of high-salt wastewater treatment, the design capacity of the gas-water separation device cannot meet the needs of increased production capacity, resulting in the inability to recycle the evaporated water, causing waste. Utility Model Content

[0003] The utility model provides a gas-liquid separation device, which overcomes the deficiencies of the prior art and can effectively solve the problem that the evaporated water cannot be recycled and wasted due to the inability of the prior gas-liquid separation device to meet the demand for increased production capacity.

[0004] In order to solve the above problems, the utility model discloses a gas-liquid separation device, comprising an aerosol diffusion channel and a water collecting tank; the inlet of the aerosol diffusion channel is fixedly connected with an air inlet pipe, the outlet of the aerosol diffusion channel is fixedly connected with an air outlet pipe, and the outside of the aerosol diffusion channel is fixedly connected with a water collecting tank; a condensation water collecting orifice plate is provided on the inside of the air inlet pipe; an inlet water collecting ring is provided at the inlet of the aerosol diffusion channel, and an outlet water collecting ring is provided at the outlet of the aerosol diffusion channel; a liquid level meter and a conductivity meter are fixedly installed on the water collecting tank, and a temperature and pressure detector is fixedly installed on the air inlet pipe, the aerosol diffusion channel and the air outlet pipe.

[0005] The aerosol diffusion channel comprises a first connecting tube, a first tapered tube, a second connecting tube, a second tapered tube and a third connecting tube which are connected in sequence. The inner diameters of the first connecting tube and the third connecting tube are equal and smaller than the inner diameter of the second connecting tube.

[0006] A guide cone plate is provided on the inner side of the aerosol diffusion channel at the outer side of the inlet water collecting circle.

[0007] The above also includes a conical shell, the outer side of the aerosol diffusion channel is fixedly connected to the conical shell, and the lower end of the conical shell is fixedly connected to the water collecting tank.

[0008] The utility model allows the evaporating air to enter through the air inlet pipe. During the entry process, the ultrafine water droplets entrained hit the condensation water collecting orifice plate, causing some of the ultrafine water droplets to burst and further evaporate. The air flows through the inlet collecting circle and the outlet collecting circle, intercepting the condensed water to the inside of the water collecting box, and the air separated from the water is discharged through the air outlet pipe, thus realizing gas-liquid separation. The device can be set according to the production capacity requirements, so it can meet the gas-liquid separation work of evaporated water under large production capacity conditions, so that the evaporated water can be recycled, avoiding the waste of evaporated water.

DETAILED DESCRIPTION

[0012] The present invention is not limited by the following embodiments, and specific implementation methods can be determined according to the technical solution of the present invention and actual conditions.

[0013] The present invention is further described below in conjunction with the embodiments and drawings:

[0014] like Figure 1 As shown, a gas-liquid separation device comprises an aerosol diffusion channel and a water collecting box 1; the inlet of the aerosol diffusion channel is fixedly connected with an air inlet pipe 2, the outlet of the aerosol diffusion channel is fixedly connected with an air outlet pipe 3, and the outside of the aerosol diffusion channel is fixedly connected with the water collecting box 1; a condensation water collecting orifice plate 4 is provided on the inner side of the air inlet pipe 2; an inlet water collecting ring 5 is provided at the inlet of the aerosol diffusion channel, and an outlet water collecting ring 6 is provided at the outlet of the aerosol diffusion channel; a liquid level meter 7 and a conductivity meter 8 are fixedly installed on the water collecting box 1, and a temperature and pressure detector 9 is fixedly installed on the air inlet pipe 2, the aerosol diffusion channel and the air outlet pipe 3.

[0015] Among them, the inlet water collecting circle 5 is made of metal mesh filter cloth with an aperture rate of less than 50 meshes, and has good permeability and corrosion resistance; the outlet water collecting circle 6 is made of metal sintered membrane with an aperture rate of not less than 150 meshes, which can better filter the overflow of air masses.

[0016] The condensation water collecting orifice plate 4 can be elliptical, arranged obliquely in the air inlet pipe 2, with a water collecting tank at the bottom, and small holes evenly distributed on the plate, with a hole distribution rate of 40-50%. The temperature and pressure detector 9 is used to detect the corresponding temperature and pressure respectively, so as to facilitate real-time monitoring of the device.

[0017] The liquid level meter 7 is used to detect the liquid level inside the water collecting tank 1; the conductivity meter 8 is used to detect and judge the water quality of the condensed water in the water collecting tank 1 and determine its destination.

[0018] During operation, the evaporating gas flows in through the air inlet pipe 2. The ultrafine water droplets carried in the process hit the condensation water collecting orifice plate 4, causing some of the ultrafine water droplets to burst and evaporate further. The gas flows through the inlet water collecting circle 5 and the outlet water collecting circle 6, intercepting the condensed water to the inside of the water collecting box 1. The air separated from the water is discharged through the air outlet pipe 3, thus realizing gas-liquid separation. The device can be set according to the production capacity requirements, so it can meet the gas-liquid separation work of evaporated water under large production capacity, so that the evaporated water can be recycled, avoiding the waste of evaporated water.

[0019] like Figure 1 As shown, the aerosol diffusion channel includes a first connecting pipe 10, a first tapered pipe 11, a second connecting pipe 12, a second tapered pipe 13 and a third connecting pipe 14 which are connected in sequence. The inner diameters of the first connecting pipe 10 and the third connecting pipe 14 are equal and smaller than the inner diameter of the second connecting pipe 12. Thus, by changing the diameter of the aerosol diffusion channel, the pressure in the aerosol diffusion channel is increased, and the inner side of the aerosol diffusion channel can be cooled to facilitate condensation of steam in the aerosol diffusion channel.

[0020] like Figure 1 As shown, a guide cone plate 15 is provided inside the aerosol diffusion channel at the outer side of the inlet water collecting circle 5. The guide cone plate 15 is used to evenly distribute the aerosol flow to the inlet water collecting circle 5, and further condense the entrained water droplets. An axial flow fan can also be used to pressurize and evenly distribute the airflow entering the aerosol diffusion channel.

[0021] like Figure 1 As shown, it also includes a conical shell 16, the outer side of the aerosol diffusion channel is fixedly connected with the conical shell 16, and the lower end of the conical shell 16 is fixedly connected with the water collecting tank 1. Thus, the collection of condensed water is facilitated.
