Description
Technical Field
The utility model relates to a shale oil refinery sealing device technical field, a heating furnace valve dry-type sealing device specifically says so.
Background
The device is applied to the sealing of the upper cover of the water seal large gyroscope of the heating furnace and the safety helmet at the top of the heating furnace of the oil refining device of the ABCD part of the shale oil refinery, the temperature of the large gyroscope of the heating furnace and the temperature of the safety helmet are 8000-1000 ℃, the original device adopts a steel structure basin structure, and the water consumption is large because the temperature of the top of the steel structure needs to be frequently supplemented with water by water; the water evaporation generates a large amount of evaporation, and because the used water is circulating water, the water pollution causes harmful substances in the steam, thereby polluting the atmosphere and being not beneficial to environmental protection; once the upper safety helmet is started, a large amount of hot water is splashed out, which easily causes personal injury. The existing 12 heating furnaces consume dozens of tons of water every day, and are used for solving the problems of water resource waste and environmental protection and preventing personal injury accidents. The utility model aims to solve the problem of avoiding using cooling water so as to avoid causing water pollution and provide a novel sealing device.
Disclosure of Invention
The utility model provides a dry-type sealing device for a heating furnace valve.
The purpose of the utility model is realized like this: the utility model provides a heating furnace valve dry-type sealing device, includes the sealing device body, its technical essential is: the sealing device comprises a sealing device body and is characterized in that the upper part of the sealing device body is cylindrical, two sealing layers are arranged in the sealing device body, each sealing layer comprises a 50-mesh steel wire mesh layer, a fire-resistant felt layer and a heat-preservation nail, the fire-resistant felt layers are located between the 50-mesh steel wire mesh layers, the heat-preservation nails penetrate through the 50-mesh steel wire mesh layers and the fire-resistant felt layers, one sealing layer is located at the top of the cylindrical structure, the cylindrical port of the upper part of the sealing device body is T-shaped, and the other sealing layer is built at the T-; the outer wall of the sealing device body is wrapped with a refractory material layer, and a shell is arranged outside the refractory material layer.
The utility model has the advantages and beneficial effects that: does not use cooling water to seal, avoids the pollution of cooling water and the consumption of water resource, the utility model discloses still have characteristics such as simple structure, easy and simple to handle.
Drawings
FIG. 1 is a schematic view of the structure of the present invention in half section;
the reference numbers are as follows: 1. the sealing device comprises a sealing device body, a steel wire mesh layer 2 on the upper portion of the sealing device body, a 50-mesh steel wire mesh layer 3, a fireproof felt layer 4, heat preservation nails 5, a cylindrical port 6, a fireproof material layer 7 and a shell.
Detailed Description
Referring to fig. 1, a dry sealing device for a heating furnace valve comprises a sealing device body, wherein: the sealing device comprises a sealing device body and is characterized in that the upper part of the sealing device body is cylindrical, two sealing layers are arranged in the sealing device body, each sealing layer comprises a 50-mesh steel wire mesh layer, a fire-resistant felt layer and a heat-preservation nail, the fire-resistant felt layers are located between the 50-mesh steel wire mesh layers, the heat-preservation nails penetrate through the 50-mesh steel wire mesh layers and the fire-resistant felt layers, one sealing layer is located at the top of the cylindrical structure, the cylindrical port of the upper part of the sealing device body is T-shaped, and the other sealing layer is built at the T-; the outer wall of the sealing device body is wrapped with a refractory material layer, and a shell is arranged outside the refractory material layer.
The first embodiment is as follows: sealing device body upper portion 1 is the tube-shape, and the inside 50 mesh steel wire net layers 2 that are provided with of tube-shape sealing device body is provided with fire-resistant felt layer 3 between the 50 mesh steel wire net layers, and heat preservation nail 4 passes 50 mesh steel wire net layers and fire-resistant felt layer, and tube-shape port department 5 on sealing device body upper portion is the T shape, and fire-resistant felt layer and 50 mesh steel wire net layers are taken at the T shape port department of tube-shape sealing device body.
The outer wall parcel on sealing device body upper portion has refractory material layer 6, and the refractory material layer is provided with casing 7 outward, and the dry-type sealing device that adopts refractory material and steel construction to combine together can effectively seal the upper cover of oil refining device heating furnace, has overcome the drawback that original water seal method brought. And because the arrangement of the refractory material can effectively reduce the energy loss, the refractory material has certain heat preservation property. The preparation is used. The heat-preservation nail made of the Cr25Ni20 material can resist aging and high temperature, and the service life of the sealing device is prolonged.
The upper end of the sealing device body is also provided with a safety cap. The safety helmet is internally provided with a sealing gasket formed by overlapping a refractory felt layer and a 50-mesh steel wire mesh layer, and the sealing gasket is fixed together through a heat-preservation nail.
