Abstract
The utility model discloses a synthesis vessel heating device, which comprises a heat traced pipe (1) and an automatic distributed control system (DCS) (2), wherein the heat traced pipe (1) is controlled by the automatic DCS. The synthesis vessel heating device comprises two segments of heat traced pipes (1, 2) which have the same structure and are connected in parallel and two sets of automatic DCSs (3, 4) which have the same structure and are connected in parallel. By adopting the technical proposal, the synthesis vessel heating device can adjust the segments of heating systems at the right time in different stages of reaction, so as to save heat in the case of low heat consumption requirement of the reaction and sufficiently supply heat in time in the case of high heat consumption requirement of the reaction, thereby effectively satisfying the heat demand and ensuring product quality of saturated polyester synthesis in a large-volume synthesis vessel.
Description
Technical field
The utility model belongs to the technical field of Chemical Manufacture process equipment, and more particularly, the utility model relates to a kind of synthesis reactor heating plant.
Background technology
At present, during polyester is synthetic, need a large amount of heat energy, our common employed heat-supplying mode all as shown in Figure 1.This heat supply structure is very general and practical.But when saturated polyester synthesis reactor volume was bigger, many problems appearred in this heat supply structure, and at first chemical reaction is in the stage of a large amount of heat energy of needs, and this heat supply structure can not satisfy the demand of energy, causes energy in time not supply with, and prolonged the reaction time; Secondly, in some specific stage, as initial reaction stage, the material of adding is less, if having only chuck and inner coil pipe, can cause heat energy too much so, too much energy is wasted, because material can not cover inner coil pipe fully, causes material and coil pipe contact-making surface hot-spot simultaneously, the material color and luster is deepened, influenced the quality of final products.
The utility model content
Problem to be solved in the utility model provides a kind of synthesis reactor heating plant, its objective is the demand of the synthetic saturated polyester of big volume synthesis reactor to heat energy that solve.
To achieve these goals, the technical scheme taked of the utility model is:
This synthesis reactor heating plant that the utility model provides, comprise heating companion pipe and automation DCS control system, described automation DCS concentrates distribution type control system, heating companion pipe is controlled by automation DCS control system,: described synthesis reactor heating plant, form by two sections heating companion's pipes (1,2), two cover automation DCS control systems, and its structure is identical, adopts parallel ways of connecting.
Described heating companion pipe is wound in the synthesis reactor outer wall for the coiled structure.
Adopt technique scheme, make the utility model in the different stages of reaction, each section of timely adjustment heating system, under the few situation of reaction needed heat energy, can save heat energy, under the situation of a large amount of heat energy of reaction needed, also can in time supply with fully simultaneously, solved the demand of the synthetic saturated polyester of big volume synthesis reactor effectively, the product quality requirement when having ensured simultaneously big volume synthesis reactor synthesizing polyester again to heat energy.
Description of drawings
Below expressed content of each width of cloth accompanying drawing of this specification and the mark among the figure are briefly explained:
Fig. 1 is the schematic diagram that has only one section heating system described in this specification background technology
Fig. 2 the utility model has the schematic diagram of two sections heating systems
Be labeled as among the figure: 1, heating companion pipe, 2, automation DCS control system, 3, heating companion pipe, 4, automation DCS control system
The specific embodiment
Contrast accompanying drawing below, by description to embodiment, to effect and operation principle, the manufacturing process of the mutual alignment between the shape of the specific embodiment of the present utility model such as related each member, structure, the each several part and annexation, each several part and manipulate method etc., be described in further detail, inventive concept of the present utility model, technical scheme had more complete, accurate and deep understanding to help those skilled in the art.
The utility model is a kind of synthesis reactor heating plant, comprise heating companion pipe 1 and automation DCS control system 2, described automation DCS concentrates distribution type control system, heating companion pipe 1 is by 2 controls of automation DCS control system, described synthesis reactor heating plant, accompanying pipe 1 and heating companion to manage 2, two cover automation DCS control systems by the i.e. heating of two sections heating companion pipes is that automation DCS control system 3 and automation DCS control system 4 are formed, and its structure is identical, adopts parallel ways of connecting.
DCS is meant that concentrating scattered control system is the general name of a control system, and this control system can be made up of PLC, industrial computer etc.The effect of DCS is exactly to adopt an on-the-spot control object that relatively disperses modes such as an electricity, gas, hydraulic pressure to focus on a control room (central station of floating dock) everywhere to control and monitor. control cost the automation of realization high concentration with minimizing.DCS mainly uses huge at the scene, and the many occasions of the complicated quantity of each control module are such as power plant, chemical plant or the like.)
At chemical reaction in earlier stage, the material that is added is less, approximately is about 3/5 of whole synthesis reactor, at this moment, promptly opens bottom heating companion pipe 1 by DCS control system automatic regulating valve door.After reaction enters into certain phase, need in synthesis reactor, add auxiliary material again, at this moment, material has reached 2/3 of whole synthesis reactor approximately, and this moment, the reaction needed heat strengthened, and at this moment, all heat supply parts all participate in heat supply, can satisfy the needs of reaction pair heat energy.
Heating companion pipe described in the utility model and 1 is wound in the synthesis reactor outer wall with heating companion pipe 2 for the coiled structure.
In the different stages of reaction, each section of timely adjustment heating system under the few situation of reaction needed heat energy, can be saved heat energy, under the situation of a large amount of heat energy of reaction needed, also can in time supply with fully simultaneously.Solved the demand of the synthetic saturated polyester of big volume synthesis reactor effectively to heat energy.
The technical scheme that the utility model adopted and the specific embodiment thereof, tangible difference is compared with prior art arranged, possessed outstanding substantial characteristics, and obtain marked improvement technically, has value in industrial promotion and application, so, the utlity model has novelty, creativeness and practicality.
In conjunction with the accompanying drawings the utility model has been carried out exemplary description above; obviously the utility model specific implementation is not subjected to the restriction of aforesaid way; as long as adopted the improvement of the various unsubstantialities that method of the present utility model design and technical scheme carry out; or design of the present utility model and technical scheme are directly applied to other occasion without improving, all within protection domain of the present utility model.
