A portable glass window defogging system for pressure vessels

Abstract

The invention discloses a portable glass window defogging system for a pressure container, and belongs to the technical field of defogging of a glass product. The glass window defogging system mainlycomprises a digital display unit, a control unit and a power adjustment unit which are arranged in a portable box body, wherein the power adjustment unit is used for energizing and heating coating quartz glass, a high-temperature resistant magnetic suction disc is attached onto a window flange, a specially-fabricated press plate is connected with the magnetic suction disc, a heater and the windowglass are pressed by an electrode fixing bolt so that heat is transferred to the window glass from the quartz glass for defogging, and a temperature measurement component is pasted on the window glassand is used for monitoring a temperature of the window in real time. The glass window defogging system is simple in structure, is convenient to disassemble and assemble, is an independent system andis suitably arranged at outer sides of pressure container windows with various sizes and various facing directions, the glass surface temperature of the pressure container window is automatically adjusted according to demand under the condition of no damage to transmittance of the window glass and bearing capability of the pressure container, so that the window is prevented from being fogged.

Description

technical field [0001] The invention discloses a portable glass window defogging system for pressure vessels, which belongs to the technical field of defogging glass products. Background technique [0002] When the pressure vessel contains high-temperature steam, the steam will condense and form water droplets on the inner surface of the glass window because the external temperature is lower than the saturation temperature of the steam. Due to the refraction effect of water droplets on the inner surface of the glass window, the observation function of the window is limited, and some advanced optical measurement equipment (such as PIV, PLIF, LDV, etc.) cannot measure the inside of the pressure vessel through the glass window. At the same time, for large pressure vessels, there are many glass windows, and a fixed defogging system needs to be installed on each glass window, which will undoubtedly increase the cost and bring inconvenience to the actual use process.

Problems solved by technology

If this technology is applied to the field of defogging the window of the pressure vessel, this method uses thermal resistance wire heating, which affects the permeability of the glass, and it is inconvenient to move, and the resistance wire power line needs to pass through the pressure vessel, which will affect the compressive strength of the pressure vessel. and sealing effect

The invention patent with the patent publication number of CN103200717A discloses real-time monitoring of the temperature of the inner and outer surface of the window glass by setting the temperature sensor inside the window and the temperature sensor outside the window. To detect the temperature of the glass body and the outside of the glass, the invention patent with the publication number CN103444259A discloses that the temperature of the windshield is detected by setting a plurality of temperature sensors, and these temperature sensors are arranged on the inside and outside of the glass or attached to the surface of the glass , because the lead wire of the temperature sensor goes out of the pressure vessel, it will affect the pressure resistance and sealing of the pressure vessel, and the above-mentioned patent technology requires technical treatment of the window glass, which violates the national standard for window glass for pressure vessels, and is inconvenient to install and disassemble, and cannot be used flexibly
