Description
TECHNICAL FIELD
[0001] Embodiments of the present disclosure relate to the technical field of protective doors, and in particular, to a hot flue gas box protective door structure. BACKGROUND
[0002] A hot flue gas box is a device component used for treating hot flue gas in industrial production. After high-temperature flue gas enters the box from the inlet, a series of processing processes are performed in the box, for example, by arranging different channels and devices, the flow rate and flow direction of the hot flue gas can be changed to achieve gas-solid separation, heat exchange, etc. Sometimes heat exchange tubes are arranged in the box to heat other media using the heat of the hot flue gas to recover part of the heat energy.
[0003] The side wall of the hot flue gas box in the prior art is provided with a protective door for maintenance. However, the protective door in the prior art is mostly made of simple metal material. Since the metal itself has a high thermal conductivity, heat is easily conducted to the outside through the door body, resulting in a large amount of heat loss. This not only causes waste of energy and increases the production cost of enterprises, but also makes the ambient temperature of the hot flue gas box too high, which poses a safety hazard to the working environment of the operators and may cause accidents such as scalding.
[0004] To improve this situation, thermal insulation materials are installed on the protective door to improve the heat insulation performance of the protective door. The thermal insulation materials in the prior art are generally fixed between the thermal insulation plate and the protective door by pasting or fixing members. However, since the temperature in the hot flue gas box is high, the adhesive between the thermal insulation plate and the protective door is prone to falling off, thereby affecting the installation stability between the thermal insulation plate and the protective door and the thermal insulation effect. If the thermal insulation plate is installed using fixing members, holes need to be punched on the thermal insulation plate and the protective door, and then the fixing members such as bolts and buckles are inserted into the punched holes and fixed firmly with tools. However, since the fixing members penetrate the thermal insulation plate and the protective door, heat is easily lost through the fixing members, thereby affecting the thermal insulation effect of the protective door. Moreover, the fixing members are prone to deformation due to heat, thereby affecting the installation stability of the thermal insulation plate. CONTENT OF THE UTILITY MODEL
