Abstract
The utility model provides a reactor for chemical industry production, relating to a reactor. The reactor comprises an elliptical seal head, a skirt, a seal head, a liquid inlet distributor and a connecting component, and is characterized in that the liquid inlet distributor of the reactor and a top adapter tube are arranged relatively independently, the elliptical seal head 2 and a cylinder 3 are installed and welded and then are installed and welded together with the skirt 1, a liquid material inlet is formed at the top of an upper seal head and connected with the liquid inlet distributor 5 by a flange, a pipe orifice convenient to operate is arranged at one side of a tank body and provided with the connecting component 4. The reactor has a vertical structure. According to the reactor, the liquid inlet at the top of the upper seal head of the reactor and the inlet distributor inside the equipment form a detachable structure form, so that the purpose of conveniently changing branch tubes of the distributor can be achieved.
Description
Technical field
The utility model relates to a kind of reactor, particularly relates to the reactor that a kind of Chemical Manufacture is used.
Background technology
The structure of reactor of Chemical Manufacture use in the past; top liquid-inlet and import distributor adopt the structural shape that directly is weldingly connected and connects by adapter mostly; run into arm on the distributor owing to reasons such as liquid material purity and corrosivity cause loss through regular meeting in actual use; when this moment, arm need be changed; it is very unreasonable that such structural shape just seems, also brings a lot of unnecessary troubles to production.This kind structural shape causes arm to be difficult for changing.
Such as, be applied to the reactor of chemical enterprise PTMEG project, suitability for industrialized production PTMEG is mainly formed through the cation ring-opening polymerisation by oxolane (THF), the main production flow process be oxolane under the effect of catalyst through polymerization, process output PTMEG such as refining.Be white waxy solid under the PTMEG normal temperature, dissolve the back and be transparent, colourless liquid.Mainly for the production of spandex, polyurethane elastomer and fat ether copolymer elastomer.The maximum consumption market of external PTMEG is spandex (49%), secondly is polyurethane elastomer (36%) and fat ether copolymer elastomer (15%), domestic spandex and the polyurethane elastomer of being mainly used in.
Summary of the invention
The reactor that provides a kind of Chemical Manufacture to use is provided the purpose of this utility model.This reactor makes the structural shape that forms detachable between the import distributor of the liquid-inlet at reactor upper cover top and device interior, thereby reaches the purpose that is convenient for changing distributor branch pipes.
The purpose of this utility model is achieved through the following technical solutions:
The reactor that a kind of Chemical Manufacture is used, comprise ellipse head, skirt, end socket, liquid-inlet distributor, attaching parts, relatively independent setting is taken at described liquid reactor import distributor and top, behind ellipse head and the cylindrical shell assembly welding with the skirt assembly welding, at the upper cover top liquid material import is set, be connected with adopting flange between the liquid-inlet distributor, be provided with the mouth of pipe of being convenient to operate in a side of tank body, the mouth of pipe is provided with attaching parts.
The reactor that described a kind of Chemical Manufacture is used, its described reactor is vertical structure.
Advantage of the present utility model and effect are:
The utility model makes when changing arm easy to operate, has avoided changing the trouble of distributor branch pipes.
Description of drawings
Fig. 1 is the utility model overall structure schematic diagram.
The specific embodiment
Be elaborated below in conjunction with the utility model of embodiment.
The utility model reactor adopts the vertical structure pattern, behind ellipse head 2 and cylindrical shell 3 assembly weldings with skirt 1 assembly welding, at the upper cover top liquid material import is set, be connected with adopting flange between the liquid-inlet distributor 5, side at tank body is provided with the mouth of pipe of being convenient to operate, and the mouth of pipe is provided with attaching parts 4, and material is evenly distributed on the beds of inside reactor by liquid-inlet distributor 5, and with catalyst 6 polymerization reaction take places, form product at last.This reactor is applied to chemical enterprise PTMEG project, and ruuning situation is good.The utility model adopts flange to connect between the adapter of end socket top and import distributor, so just make liquid-inlet distributor and top joint pipe structure relatively independent, arm on the distributor can be sent by the manhole at upper cover top after dismounting when needs are changed, be convenient to the replacing of arm on the distributor, flexible and convenient operation.
Claims (2)
1. reactor that Chemical Manufacture is used, comprise ellipse head, skirt, end socket, liquid-inlet distributor, attaching parts, it is characterized in that, relatively independent setting is taken at described liquid reactor import distributor and top, behind ellipse head (2) and cylindrical shell (3) assembly welding with skirt (1) assembly welding, at the upper cover top liquid material import is set, be connected with adopting flange between the liquid-inlet distributor (5), side at tank body is provided with the mouth of pipe of being convenient to operate, and the mouth of pipe is provided with attaching parts (4).
