Embodiment

[0032] 1. High temperature resistant and anti-corrosion structure on the bottom of the liquid sulfur pool

[0033] Such as figure 1 As shown, the high-temperature resistant and anti-corrosion structure on the bottom of the liquid sulfur pool is composed of a sulfur pool bottom plate 3, a thermal insulation pouring layer 2, and an alumina tile layer 3 from bottom to top. Reserved anchors4.

[0034] The physical and chemical properties of the thermal insulation pouring layer 2 are as follows:

[0035] Bulk density, 110℃×24h ≥2.3g / cm 2

[0036] Compressive strength, 110℃×24h ≥50Mpa

[0037] Linear change after high temperature firing, 8150℃×3h -0.2~0.

[0038] The thermal insulation pouring layer is made of thermal insulation pouring material, and the thermal insulation casting material is a product named high temperature aluminum refractory castable produced by Zibo Huaqing Refractory Material Co., Ltd.

[0039] The alumina tile layer 3 is made of alumina tiles, and the al...

Abstract

The invention relates to a high-temperature resistant and anti-corrosion structure for a liquid sulfur pool, and belongs to the technical field of sulfur reclamation. The high-temperature resistant and anti-corrosion structure for the liquid sulfur pool is characterized by consisting of a sulfur pool wall board, an insulated casting layer and an aluminum oxide tile layer, wherein the sulfur pool wall board and the insulated casting layer are provided with anchoring pieces. The method adopts a material which has similar property and nearly same expansion coefficient as the concrete and has small heat conductivity and good insulating and anti-corrosion properties, has quite convenient construction, can ensure long-term safe use of the liquid sulfur pool, and reduce maintenance and repair cost greatly.

Description

technical field [0001] The invention belongs to the technical field of sulfur recovery, and in particular relates to a high-temperature-resistant and anti-corrosion structure of a liquid sulfur pool and a construction method thereof. Background technique [0002] The working temperature of concrete is below 50°C, and the temperature of liquid sulfur is about 180°C. The high temperature and strong acid environment can easily cause damage to the structure of the liquid sulfur pool. The anti-corrosion of the liquid sulfur pool in the existing sulfur recovery device mostly adopts one bottom, two cloth, three coatings of anti-corrosion structural glue or similar FRP products, and there is also a method of lining the pool with a layer of stainless steel plate, and the heat insulation mainly adopts internal or external construction Heat-resistant insulation bricks. The traditional method has many shortcomings, such as using heat-resistant insulation bricks inside and pasting anti-...
