Embodiment 1

[0016] Such as figure 1 , the present embodiment provides a polymer supercritical gas foaming production line, including a production module, a thermal oil heating furnace 8 and a cooling module; , gas circulation storage tank 3, gas booster pump 4, gas heater 5, reaction kettle 6 and normal pressure drying furnace 7; described gas heater 5 and reaction kettle 6 are connected with thermal oil heating furnace 8, and heating oil passes through The hot oil outlet of the hot oil heating furnace 8 enters the gas heater 5 and the reaction kettle 6 in turn, and then flows into the hot oil heating furnace 8 through the hot oil return port; the cooling module includes a cold water circulation device 11, a refrigeration unit 12 and The cold water storage tank 13 and the refrigeration unit 12 are respectively connected with the cold water circulation device 11 and the cold water storage tank 13, and the water in the cold water circulation device 11 is further cooled and then introduced i...

Embodiment 2

[0018] This embodiment provides a polymer supercritical gas foaming production line. Compared with the production line in Embodiment 1, this embodiment has been further improved: the cooling water circulation device 10 is connected with the primary condenser 9, and the supercritical gas is initially Cooling: the cold water storage tank 13 is connected with the deep condenser 10, and the supercritical gas is cooled twice, so that the original cooling system of the production line is used to cool down the gas recovery system. equipment purchase and maintenance costs. In addition, according to different types of polymers, the reactor 6 can be configured as a horizontal reactor or a vertical reactor.

Abstract

The invention provides a polymer supercritical gas foaming production line which comprises a production module, a hot oil heating furnace, a cooling module and a gas recovery module. High-temperature gases generated in a polymer foaming process are recovered by the gas recovery module, then cooled twice by the cooling system, and instantly enters into the production module for polymer foaming production while achieving an approximate temperature. The amount of gases consumed in the whole production process is greatly reduced, the production efficiency and the production continuity are improved, the production cost brought by gas wastes is eliminated, the production effect is effectively improved, energy is saved and the benefits are improved.

Description

technical field [0001] The invention relates to a polymer foaming production line, in particular to a polymer supercritical gas foaming production line with gas recovery function. Background technique [0002] Foam plastic has the advantages of light weight, heat insulation, sound insulation, cushioning, high specific strength, and low price. Therefore, it is widely used in packaging, industry, agriculture, construction, transportation, military industry, aerospace industry and daily necessities. . Generally speaking, polymer foaming methods can be divided into two methods: chemical foaming and physical foaming. However, foamed materials prepared by chemical foaming methods often pollute the environment, and the performance and price of their products are worse than those prepared by relatively physical foaming methods. Therefore, in recent years with CO 2 , N 2 , Butane and pentane etc. are the physical foaming method of physical foaming agent and have been widely used....
