Description
Technical Field
The utility model particularly relates to a polyol, polyurethane waste gas recycle device.
Background
When polyol, polyurethane production, need the evacuation in the reation kettle, when the evacuation, have a small amount of gaseous state material to get into the vacuum pipe in, because of the pipeline difference in temperature when the vacuum pipe used for a long time, the crystallization material can appear in the inner wall, attached to on the above-mentioned pipeline wall, remaining crystallization material if not handle in time, can occupy the pipeline space and cause vacuum pressure not enough, can not satisfy the technological requirement, reduction production efficiency and product quality. This problem can only be solved by replacing the pipe with a new one. The replacement of the pipeline needs shutdown operation, which wastes time and labor and affects the production efficiency; the labor cost for dismounting and mounting the pipeline is high, and the cost is increased when a new pipeline is replaced; the crystal material attached to and remained on the inner wall of the removed pipeline is also wasted, and the crystal material can cause pollution to the environment.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a polyol, polyurethane waste gas recycle device, it can make the interior crystallization material used repeatedly of vacuum tube, reduces the pipeline inner wall and hangs the material.
The utility model discloses a realize through following technical scheme:
the utility model provides a polylol, polyurethane waste gas recycle device, includes reation kettle, and reation kettle is connected with main vacuum tube, still is equipped with branch vacuum tube between its characterized in that reation kettle and the main vacuum tube, has concatenated the buffer tank on the branch vacuum tube, and the jar body of buffer tank is for pressing from both sides the cover design, and the upper portion side is equipped with steam inlet, cooling water outlet, and the lower part side is equipped with the cooling water inlet, and the lower terminal surface is equipped with the outlet.
The utility model discloses a branch's vacuum tube, steam inlet, cooling water export, cooling water import and drain outlet department all are equipped with the valve.
The utility model discloses the steam inlet of buffer tank passes through the pipeline and is connected with steam generator, and the cooling water import of buffer tank passes through the pipeline and is connected with the cooling water pitcher.
The utility model discloses automatic opening water circulating system cooling buffer tank when using the evacuation, let the gaseous state material cooling of buffer tank of flowing through become the solid, prevent that it from getting into main vacuum tube.
When the vacuumizing is stopped, the cooling water in the jacket of the buffer tank is drained through the water outlet, steam is introduced into the jacket of the buffer tank to heat the buffer tank, so that solid materials in the tank are melted into liquid, and the liquid is refluxed into the reaction kettle through the branch vacuum tube to continuously participate in the reaction.
The utility model has the advantages of as follows:
1) reducing the wall hanging amount of the crystallized materials in the main vacuum tube;
2) the main vacuum tube does not need to be frequently replaced, and the production efficiency is improved.
3) The labor and material costs are reduced.
4) The waste of the material is reduced, the material is repeatedly utilized, and the benefit is increased.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
As shown in the figure: 1. a reaction kettle; 2. branching vacuum tubes; 3. a cooling water inlet; 4. a steam inlet; 5. a buffer tank; 6. a cooling water outlet; 7. a main vacuum tube; 8. and a water outlet.
Detailed Description
Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and therefore are only examples, and the protection scope of the present invention is not limited thereby. It is to be noted that unless otherwise specified, technical or scientific terms used herein shall have the ordinary meaning as understood by those skilled in the art to which the present invention belongs.
As shown in fig. 1: a branch vacuum tube 2 is arranged in front of a reaction kettle 1 and a main vacuum tube 7, a buffer tank 5 is connected in series on the branch vacuum tube 2, the buffer tank 5 is designed as a jacket, a steam inlet 4 and a cooling water outlet 6 are respectively arranged on the left side and the right side of the upper part of a tank body, a cooling water inlet 3 is arranged on the left side of the lower part of the tank body, and a water outlet 8 is arranged on the lower end face of the tank body.
The utility model discloses during the use:
1. when the reaction kettle 1 is vacuumized, the valves at the cooling water inlet 3 and the cooling water outlet 6 are opened, the valves at the steam inlet 4 and the water outlet 8 are closed, cooling water is introduced into the jacket of the buffer tank 5, the temperature in the buffer tank 5 is reduced, and the gaseous material passing through the buffer tank 5 is cooled, solidified and temporarily stored in the tank.
2. When the reaction kettle 1 does not need to be vacuumized, the valves at the cooling water inlet 3 and the cooling water outlet 6 are closed, the valve at the water outlet 8 is opened, and water is drained.
3. When no cooling water is in the jacket of the buffer tank 5, the valve at the steam inlet 4 is opened, the valve at the water outlet 8 is closed, steam is introduced into the jacket of the buffer tank 5, the temperature rises until the solidified material is melted, and the liquid material automatically flows back to the reaction kettle 1 through the branch vacuum tube 2.
4. Repeating the steps and recycling.
The above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications and substitutions do not substantially depart from the scope of the embodiments of the present invention, and are intended to be covered by the claims and the specification.
