Abstract
The utility model relates to production equipment of polyurethane, and in particular relates to a raw material drying room of polyurethane prepolymer. The raw material drying room is characterized in that a plurality of raw material barrels are arranged in the raw material drying room, a pore plate is arranged at the bottom of the drying room, a heating pipe is arranged below the pore plate, and the wall of the drying room consists of a heat insulation layer on the outer side and a reflecting layer on the inner side. The raw material drying room disclosed by the utility model can fully use the waste heat of a reaction system to preheat raw materials in a packaged state, so that the heat is fully used.
Description
Technical field
The utility model relates to a kind of polyurethane production equipment, specifically a kind of base polyurethane prepolymer for use as raw material drying room.
Background technology
The temperature of reaction of base polyurethane prepolymer for use as, generally at 70-100 ℃, before raw material enters prepolymer reaction still, is generally first passed through the preheating of interchanger.Weak point by interchanger preheating is: be subject to device-restrictive, amounts of preheat is little, can not make full use of the waste heat of reactive system.
Summary of the invention
The utility model provides a kind of base polyurethane prepolymer for use as raw material drying room, can carry out preheating for the raw material of packed state, makes full use of heat.
The concrete technical scheme adopting of the utility model is:
A base polyurethane prepolymer for use as raw material drying room, is characterized in that, in described raw material drying room, a plurality of Raw material pails is set, and drying room bottom arranges orifice plate, and orifice plate below arranges heating tube, and described drying room wall consists of the thermal insulation layer in outside and the reflecting layer of inner side.
Further, described heating tube is connected with the residual heat system of base polyurethane prepolymer for use as reaction.
For making full use of base polyurethane prepolymer for use as reactive system waste heat, a plurality of drying rooms can be set, its heating tube is in parallel or be connected in series.
The utility model can make full use of reactive system waste heat, and the raw material of packed state is carried out to preheating, makes full use of heat.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of orifice plate.
Embodiment
As shown in Figure 1, 2, a kind of base polyurethane prepolymer for use as raw material drying room, arranges a plurality of Raw material pails 3 in described raw material drying room, and drying room bottom arranges orifice plate 4, and orifice plate 4 belows arrange heating tube 5, and described drying room wall consists of the thermal insulation layer 2 in outside and the reflecting layer 1 of inner side.
