Washing device

Abstract

The invention discloses a washing device. The washing device comprises a gun body, a first high-temperature steam pipe, a valve device and an extraction liquid pipe, wherein the gun body comprises a stock and gun barrel segments communicated with the stock, the gun barrel segments include the first gun barrel segment, the second gun barrel segment and the third gun barrel segment, one end of the first gun barrel segment is communicated with one end of the stock, the other end of the first gun barrel segment is communicated with one end of the second gun barrel segment through a universal joint with a hollow cavity, the second gun barrel segment is sleeved with the third gun barrel segment, one end of the third gun barrel segment is connected with the universal joint, an annular space is formed by the end of the third gun barrel segment and the universal joint, and the other end of the third gun barrel segment extends to the front side of the other end of the second gun barrel segment to form a diffusion space; the first high-temperature steam pipe is arranged in the gun body, one end of the first high-temperature steam pipe is communicated with one end of the universal joint, and the other end of the first high-temperature steam pipe extends out of the other end of the stock to be communicated with a high-temperature high-pressure steam generation device; the valve device is arranged between the stock and the first gun barrel segment and used for connecting and disconnecting the first high-temperature steam pipe; the extraction liquid pipe enters the first gun barrel segment and is communicated with the first high-temperature steam pipe and the universal joint.

Description

technical field [0001] The invention relates to a cleaning device. Background technique [0002] The internal structure of many instruments will produce fouling, dust or reaction residues due to long-term use, which needs to be cleaned. For example, the cleaning device for cleaning three-way catalysts is not very perfect. At present, most of them on the market use droppers or steam pipes for cleaning. The three-way catalyst is very difficult to operate. However, some similar products or devices on the market generally use direct heating of the cleaning liquid to generate steam, which easily destroys the molecular structure of the cleaning liquid, and the composition of the generated steam is uncertain. It may be that there is too much water vapor, and the activity of the cleaning liquid may also be in the range of It is inactivated during the heating process, and the temperature required to evaporate the cleaning solution is not easy to control. There are also some cleanin...

[0002] The internal structure of many instruments will produce fouling, dust or reaction residues due to long-term use, which needs to be cleaned. For example, the cleaning device for cleaning three-way catalysts is not very perfect. At present, most of them on the market use droppers or steam pipes for cleaning. Three-way catalyst, very difficult to operate

However, some similar products or devices on the market generally use direct heating of the cleaning liquid to generate steam, which easily destroys the molecular structure of the cleaning liquid, and the composition of the generated steam is uncertain. It may be that there is too much water vapor, and the activity of the cleaning liquid may also be in the range of Inactivation during heating, and the temperature required to evaporate the cleaning solution is not easy to control

There are also some cleaning devices that generate high-temperature steam through electric heating or oil heating, which causes fouling of watering cans, nozzles, etc., thereby affecting the service life of each component. malfunction

There are also similar devices on the market that can only spray high-temperature cleaning steam or cleaning liquid steam heated by a heater
