A method for arranging reactor steam drum and related pipelines

Abstract

The invention discloses an arrangement method of a reaction kettle steam drum and related pipelines. According to the arrangement method, a reaction kettle, a workshop operation platform walkway, a condenser and a storage tank or a metering tank, a public engineering pipeline, a steam drum and a steam drum valve group are reasonably arranged in a workshop; a reaction kettle jacket steam drum comprises two steam drums which are independently mounted in a staggered manner; the two independent steam drums are respectively an upper steam drum and a lower steam drum; the upper steam drum and the lower steam drum are connected with the public engineering pipeline through corresponding control valves or valve sets and corresponding connecting pipelines; the upper steam drum and the lower steam drum are arranged on the same workshop operation platform, the upper steam drum and the lower steam drum are arranged at a vertical or basically vertical angle with the workshop operation platform, andthe control valves or valve sets connected with the upper steam drum and the lower steam drum are arranged parallel or basically parallel to the workshop operation platform. The beneficial effects arethat: steam drum and related pipeline installation construction efficiency is high, cost is low, the steam drums and the valves are maintained and replaced quickly; the probability of misoperation ofthe valves can be greatly reduced; and frozen brine leakage is prevented and reduced.

Description

technical field [0001] The invention belongs to the field of design and equipment arrangement and installation of fine chemical workshops, and specifically provides a method for arranging reactor steam drums and related pipelines. [0002] technical background [0003] Because most of the fine chemical products are relatively complex in process, and also have the characteristics of small batches and many varieties, the workshops that produce these fine chemical products require multi-functional designs for them. Multifunctional design is a very complicated issue. Generally speaking, it is centered on the core equipment of the fine chemical workshop - the reactor, such as the supporting relationship between the reactors; there are also reactors and their matching condensers and storage tanks or metering The relationship between the tanks; and then the piping of the reactor. Among them, in order to meet the needs of the production of various fine chemical products, it is the m...

Problems solved by technology

②In order to save space, the utility pipelines connected to this "steam drum" are usually arranged and installed 1.0-1.5 meters below the walkway 42 of the workshop operation platform, so the operator cannot see when operating the relevant valves of the "steam drum" related utilities

This makes it extremely difficult to remove the outer screws when maintaining and replacing the valves, especially for repairing and replacing the frozen brine outlet valve 16 and the frozen brine discharge valve 17 that have no displacement space. Frequent maintenance and replacement of one of the valves requires the removal of the screws of the two valves. , so the efficiency of repairing and replacing these valves is very low

[0017] 3. Since these utility pipes are located under the operating platform, the installation and insulation of these pipes is inconvenient due to the narrow space, which will also cause long construction time and high construction costs.

[0018] 4. The relevant pipelines are relatively long, and the connecting pipeline between the steam drum and the utility pipeline and the pipeline between the utility pipeline and the condenser are relatively long

Since the control valves related to the steam drum are located above the steam drum, the corresponding utility pipelines must be installed and arranged above the aisle of the operation platform, so the first problem brought about is the installation and insulation. These utility pipelines and connecting pipelines are basically high-altitude operations. , so the construction is inconvenient, resulting in high construction costs; secondly, such arrangement and installation will cause a large number of steam drum connecting pipes above the aisle of the workshop operation platform, so it does not have an aesthetic effect; finally, this kind of steam drum cannot reduce the leakage of frozen brine, etc. problems, and it is impossible to achieve the effect of optimizing the layout of the workshop

[0021] Therefore, the steam drums introduced by the above two patents cannot solve the problems caused by the current typical fine chemical reactor steam drum arrangement method
