Abstract

The utility model provides a reaction vessel with inbuilt cleaning device which belongs to processing technical field and use to automatically clean the interior of the reaction vessel. The function is mainly realized through such a structure that a ring of high pressure spray pipe is installed in the reaction vessel. A plurality of high pressure liquid flow flushes the reaction vessel wall and parts arranged therein, at the same time the stirring device in the reaction vessel is powered on and is stirring accordingly, so that the reaction raffinate is flushed, diluted and cleaned by cleaning agent and finally drained out from reaction vessel discharging outlet together with the cleaning agent. The utility model avoids manually cleaning or cleaning with large amount of solvent.

Description

A kind of reactor that is provided with interior cleaning apparatus

Technical field:

A kind of reactor that is provided with interior cleaning apparatus belongs to the chemical industry equipment area of maintenance, and the inside that is used for reactor is cleaned automatically.

Background technology:

Current domestic and international chemical reaction still generally is divided into two kinds of working forms, and promptly continuity working forms and interim working forms in the continuity working forms, do not have contradiction between the industrial chemicals that chemical industry finished product in the reactor and unreacted are answered; Production as all-purpose adhesive, it mainly is a course of dissolution, and the reactor process finishes, after finished product is discharged, being trapped in interior finished product raffinate of still and initiate raw material such as rubber, Petropols, solvent etc. does not have contradiction, can not cause adverse effect to the next batch reaction; And in other reactions, synthetic as polyurethane, in the organosilicon building-up process, last consignment of reacts, the finished product raffinate of failing to discharge fully can have a strong impact on synthetic causing the reaction of next group product, reduces product quality, even make material overheated or curing in course of reaction, damage entire reaction equipment; Thereby in this reaction process, after reactor reacts each time, need cleaning reaction still inside, so that fully get rid of reaction residue.At present, traditional way is to open the reaction kettle cover, in reactor, cleans each corner in the still with cleaning agent under the staff, does like this and not only takes a lot of work but also time-consuming, and is also very dangerous; Perhaps, inject a large amount of organic solvents in reactor, the high speed rotating agitator cleans the inner each several part of washing reaction still then, discharges organic solvent at last, and so repeated multiple times need expend a large amount of organic solvents.

Summary of the invention:

Can not clean automatically for solving present reactor inside, need expend the problem of a large amount of organic solvents when perhaps cleaning, a kind of reactor that is provided with interior cleaning apparatus is now proposed, its mainly realization means are such, in reactor, one circle high-pressure spraying pipe is installed, the high-pressure spraying pipe is installed with ring-type shape, be located under the reaction kettle cover, on the agitating device, high-pressure spraying Guan Keshe mounting bracket is opened a plurality of spray apertures on the pipe, shower is by the external scavenging pump of cleaning agent pipeline, and scavenging pump connects cleaning agent tank.During use, elder generation's emptying reactor, start scavenging pump then, suck cleaning agent in the cleaning agent tank and in the high-pressure spraying pipe, inject, make cleaning agent each spray apertures ejection from the high-pressure spraying pipe, with each parts in many high pressure liquid stream impact-response inner wall of kettle and the still, stirring apparatus for reaction kettle is opened simultaneously, cooperates to stir, and makes the reaction residue that is detained on each parts in the still be cleaned agent and fully washes away, diluted then, cleaning are discharged from the reactor discharge gate together with cleaning agent at last.

Advantage of the present utility model is: avoided the mode of artificial cleaning reaction still or a large amount of solvent flood irrigation cleaning reaction stills, guaranteed the continuity of producing, reduced cost simultaneously, improved the process safety degree.

Description of drawings:

Accompanying drawing 1 is the utility model vertical section structure schematic diagram;

Accompanying drawing 2 is that the utility model is overlooked cross-sectional view;

Wherein: (1) reaction kettle body, (2) high-pressure spraying pipe, (3) spray apertures, (4) stirring apparatus for reaction kettle, (5) cleaning agent pipeline, (6) support, (7) cleaning agent tank, (8) scavenging pump, (9) reaction kettle cover, (10) high pressure liquid stream.

The specific embodiment:

As shown in Figure 1, high-pressure spraying pipe (2) is located under the reaction kettle cover (9), on the stirring apparatus for reaction kettle (4), when needs cleaning reaction still, high pressure liquid stream (10) sprays from the spray apertures (3) on the high-pressure spraying pipe (2), impact-response kettle (1) inwall, stirring apparatus for reaction kettle (4), stirring apparatus for reaction kettle (4) also cooperate stirring simultaneously, and reactor inside is fully cleaned;

As scheme shown in attached 2, high-pressure spraying pipe (2) is installed on the support (6), on open spray apertures (3), connect scavenging pump (8) by cleaning agent pipeline (5), scavenging pump (8) connects cleaning agent tank (7).

Claims

1. a reactor that is provided with interior cleaning apparatus comprises: reaction kettle body, high-pressure spraying pipe, spray apertures, stirring apparatus for reaction kettle, cleaning agent pipeline, cleaning agent tank, scavenging pump, the reaction kettle cover is characterized in that: establish the high-pressure spraying pipe in the reaction kettle body, open spray apertures on the described high-pressure spraying pipe, place under the reaction kettle cover, on the stirring apparatus for reaction kettle.

2. a kind of reactor that is provided with interior cleaning apparatus according to claim 1, described high-pressure spraying pipe connect scavenging pump and cleaning agent tank by the cleaning agent pipeline.
