Manufacturing and mounting method for coal gasification non-standard tank, as well as translation device and translation method for cylinder bodies of non-standard tank

Abstract

The invention discloses a manufacturing and mounting method for a coal gasification non-standard tank. The manufacturing and mounting method comprises the following steps: segmented cylinder bodies of the coal gasification non-standard tank are manufactured; the segmented cylinder bodies are translated through a translation device to the position of a hoisting device with a reserved concrete structure; after the segmented cylinder bodies are mounted and in butted welding from the top to the bottom in an inverted manner, the hoisting device hoists the cylinder bodies step by step until the mounting is finished. The invention further discloses a translation device for the cylinder bodies of the coal gasification non-standard tank and a method for translating the cylinder bodies of the non-standard tank by adopting the translation device. The translation device comprises a slide track I and a slide track II which are arranged in parallel and adapt to the outer diameters of the segmented cylinder bodies, wherein each slide track comprises two tracks; weight transporting devices in pairs are respectively arranged on the upper end surfaces of the slide track I and the slide track II, positioning clamps are also arranged on each pair of weight transporting device, a guiding rail I and a guiding rail II are further arranged at the bottoms of the slide track I and the slide track II respectively, two tracks of the slide track I are arranged in parallel at the top of the guiding rail I, and the two tracks of the slide track II are arranged in parallel atthe top of the guiding rail II. After the adoption of the technical scheme provided by the invention, the mounting precision of the segmented cylinder bodies of the non-standard tank is ensured.

Description

technical field [0001] The invention belongs to the field of chemical equipment, and more specifically, the invention relates to a method for manufacturing and installing a coal gasification non-standard tank. Background technique [0002] China's coal resources are relatively rich in oil and natural gas resources, so various chemical products mostly use coal as raw materials for production, among which coal gasification is a key step in synthesis, and coal gasification system is the core device in the chemical industry. Coal gasification is currently the most advanced gas Coal gasification technology has the advantages of adapting to a wide range of coal types, high efficiency, low oxygen consumption, large production capacity of a single unit, large operating flexibility, safety and environmental protection, etc. Due to the compact and dense distribution of gasification equipment, the installation site of coal gasification systems is subject to site conditions Due to the l...

[0002] China's coal resources are relatively rich in oil and natural gas resources, so various chemical products mostly use coal as raw materials for production, among which coal gasification is a key step in synthesis, and coal gasification system is the core device in the chemical industry. Coal gasification is currently the most advanced gas Coal gasification technology has the advantages of adapting to a wide range of coal types, high efficiency, low oxygen consumption, large production capacity of a single unit, large operating flexibility, safety and environmental protection, etc. Due to the compact and dense distribution of gasification equipment, the installation site of coal gasification systems is subject to site conditions Due to the limitation of the large-scale lifting equipment or crane, it is difficult to directly lift it into place; the installation method of the prior art is to reserve the structure at the production site, and then install the structure after the non-standard tank is in place. Since the large-scale lifting equipment cannot enter the site, Seriously affecting the construction progress, manual lifting and positioning not only increases the installation cost, but also poses a large safety hazard; and some devices are reserved for the installation space of the concrete structure, it is more difficult to manually position, and it is difficult to meet the production and installation of non-standard tanks; The method of installing non-standard tanks in pieces or sections. Due to the large span of the non-standard tank segmented cylinder, the cylinder is deformed by force during horizontal translation, and the installation accuracy is difficult to guarantee.
