Embodiment 1

[0026] Such as figure 1 , 2 As shown, a new type of high-pressure, corrosion-resistant, and high-temperature-resistant membrane shell includes a housing 1, the housing 1 is a hollow cylinder, the two ends of the housing 1 are connected with end caps 2, and the axial ends of the outer surface of the housing 1 are A branch pipe 3 is provided respectively, and a membrane element support 4 is provided in the corresponding position of each branch pipe 3 inside the housing 1, and each membrane element support 4 includes two opposite ring groups, and the two ring groups pass through the rib plate 5. Fixed connection, each ring group includes at least two concentric rings.

[0027] Both ends of the housing 1 are provided with end flanges 6 and are flange-connected with the end cover 2 .

[0028] The end of the branch pipe 3 is provided with a connecting flange 7, which is convenient for connecting with external equipment.

[0029] The end cover 2 includes a solid flange disc 11, th...

Embodiment 2

[0031] Such as image 3 As shown, the difference between this embodiment and Embodiment 1 is that the end cover 2 includes a stepped flange disc 21 sunken inward, and a second central tube 22 is arranged at the center of the stepped flange disc 21, and the second center The outer end of the tube 22 is provided with a second flange 23 , and several reinforcing ribs 24 are arranged between the outer root of the second central tube 22 and the concave surface of the stepped flange disc. The above-mentioned end cover saves material and reduces manufacturing cost.

[0032] The shell is directly made of materials that are resistant to high pressure, corrosion, and high temperature, such as stainless steel, titanium alloy, etc.

[0033] The inner body of the shell and the outer coating are compounded. The inner body is made of high-pressure resistant materials, such as carbon steel, and the outer coating is made of corrosion-resistant and high-temperature resistant materials, such as...

Abstract

The invention provides a novel high pressure resistant, anti-corrosion and high temperature resistant membrane shell, which comprises a shell, wherein two ends of the shell are connected with end covers; two axial ends of the outer side surface of the shell are respectively provided with a branch pipe; a membrane element bracket is arranged on a position corresponding to each branch pipe in the shell; each membrane element bracket comprises two circular ring groups which are fixedly connected through a rib plate; each circular ring group comprises at least two concentric circular rings. The invention simultaneously provides a preparation method for the novel high pressure resistant, anti-corrosion and high temperature resistant membrane shell and the preparation method thereof have the advantages of simple structure, easiness in processing, low manufacture cost, large manufacture size range and high compatibility. When the diameter is greater than 8 inches (203.2mm), the aspects including the pressure resistance degree, the flow condition, the mass transfer efficiency and the cost of the novel high pressure resistant, anti-corrosion and high temperature resistant membrane shell areall superior to that of the mainstream 8-inch membrane shell in the traditional market, a space use ratio is improved, and a larger membrane area can be provided in unit volume so as to obtain higherwater yield in the unit volume.

Description

technical field [0001] The invention relates to a membrane shell and a preparation method thereof, in particular to a membrane shell for seawater desalination and a preparation method thereof. Background technique [0002] With the deepening of the industrialization process of various countries in the world and the impact of global climate change, fresh water resources are increasingly unable to meet the needs of people's daily life and industrial development. Especially in the Middle East and industrially developed countries, seawater desalination has become an effective means to make up for the lack of freshwater resources, and China's demand for seawater desalination is also increasing day by day. [0003] Reverse osmosis membrane technology is the most advanced seawater desalination technology. It uses a semi-permeable membrane to overcome the osmotic pressure of seawater under the action of pressure to filter out the salt in seawater, thereby producing fresh water. Com...
