A reformer furnace door insulation device and its preparation method

Abstract

The invention discloses a reformer furnace door heat preservation device and a preparation method thereof, and relates to the technical field of reformer furnace door heat preservation. The device comprises a door frame heat preservation block, a furnace door conical plug and a ceramic fiber blanket, and the furnace door conical plug It includes an end plate and a four-pyramid-shaped plug-in part, one end of the end-plate is fixedly connected with the large-section end of the plug-in part, the door frame heat preservation block is fixed in the furnace door channel, and a four-pyramid-shaped hole is processed inside, and the plug-in part is set in the four-pyramid-shaped In the hole, a ceramic fiber blanket is pressed and arranged between the plug-in portion and the quadrangular pyramid hole and between the end plate and the door frame heat-insulating block. The device can quickly seal the furnace door, is simple and convenient to operate, can completely eliminate the gap with the furnace door channel, has a good thermal insulation effect, and will not collapse inward due to the burning loss of the inner side of the reformer. long lasting. The method is used for preparing the above-mentioned device, so that it can meet the technical performance index required by the device, and meet the needs of the reformer's use environment and energy saving and consumption reduction.

Description

technical field [0001] The invention relates to the technical field of reformer furnace door heat preservation, in particular to a reformer furnace door heat preservation device and a preparation method thereof. Background technique [0002] The reformer is a device for preparing synthetic gas, including natural gas steam reformer, hydrogen production reformer, carbon monoxide reformer and other types. The reformer requires a high temperature environment to prepare synthesis gas, and its temperature is usually not lower than 900 °C. According to the different preparation gases, the internal temperature of the reformer can even reach 1400 °C during operation. Therefore, it is necessary to install heat insulation at the reformer door. Insulation device to ensure a constant temperature inside the furnace and a suitable and safe ambient temperature outside the furnace door. [0003] In the prior art, the thermal insulation of the furnace door of the reformer is usually accompli...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, the thermal insulation of the furnace door of the reformer is usually completed by stacking and inserting ceramic fiber modules in the rectangular furnace door channel. This method mainly has the following problems in actual production: First, The commercially available ceramic fiber modules have a cuboid structure. When they are stacked in the rectangular furnace door channel, there will be many gaps, which will affect the heat insulation effect. Compacting, and inserting ceramic fiber blankets in the gaps, this operation process is time-consuming and laborious, extremely inconvenient, and cannot completely eliminate the gaps, and will still affect the heat insulation effect; After a period of use, the ceramic fiber module will burn from the periphery to the middle. When the burn is to a certain extent, due to the high temperature inside the reformer, the inner ceramic fiber module will burn and shrink, resulting in the entire stacked ceramic The fiber module will collapse inwards, losing the heat insulation effect. At the same time, the high-temperature airflow in the reformer will directly act on the flange steel plate of the furnace door, causing the furnace door to burn red or even burn through. At the same time, it poses a safety hazard to the surrounding staff who are easy to be burned.
