Problems solved by technology

[0003] In the traditional DME production process, when sampling the DME gas in the transport tank or gas storage tank, due to the large diameter of the exhaust port of the transport tank or gas storage tank, the gas is usually collected through the airbag. Finally, the airbag needs to be closed manually, but it takes a long time for the airbag to complete closing, which may easily cause the dimethyl ether sample gas to mix with the air, resulting in large errors in the test results

Embodiment Construction

[0020] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0021] refer to Figure 1~2 The dimethyl ether sampling adapter shown in the device includes: a cylindrical main body 3 and an air inlet 1 and a sampling end 5 arranged at both ends of the main body, the air inlet 1 and the sampling end 5 are communicated, and The outer diameter of the air intake end 1 is greater than the outer diameter of the sampling end 5, the air intake end 1 is provided with a fixing unit for fixing the device to be sampled, and the sampling end 5 and the main body 3 are passed through a sampling fixing nut 4 connections.

[0022] Wherein, the fixing unit includes: a positioning hole 6 disposed on the air inlet end and a positioning block 2 disposed...

Abstract

The invention discloses a dimethyl ether sampling transfer device, which relates to the technical field of dimethyl ether production and manufacturing. The gas end communicates with the sampling end, and the outer diameter of the air inlet end is larger than the outer diameter of the sampling end, the air inlet end is provided with a fixing unit for fixing the device to be sampled, and the sampling end and the main body are fixed by sampling Nut connection, the invention can complete the airtight transfer to the air port through the mutual cooperation of the various parts of the adapter, so that the obtained dimethyl ether gas sample is not mixed with the outside air, thereby controlling the error of the detection result.

Description

technical field [0001] The invention relates to the technical field of dimethyl ether production and manufacturing, in particular to a dimethyl ether sampling transfer device. Background technique [0002] Dimethyl ether (also known as methyl ether, referred to as DME) is a colorless gas with an ether fragrance. It has many unique uses in chemical industries such as pharmaceuticals, fuels, and pesticides. It can replace Freon as an aerosol propellant and refrigeration agents to reduce environmental pollution. DME can also be used as a substitute for city gas and liquefied petroleum gas, and it is superior to methanol as a substitute for automobile fuel. In addition, dimethyl ether can also be used as a foaming agent and coupling agent to synthesize low-carbon olefins and produce high-octane gasoline, aromatics and high-molecular-weight oxygenated hydrocarbons. [0003] In the traditional DME production process, when sampling the DME gas in the transport tank or gas storage...
