Problems solved by technology

However, most units and experimenters lack these basic common sense or have not paid enough attention to it, and the phenomenon of miscible asphalt and trichlorethylene can be seen everywhere without treatment.
There are many reasons: first, most units and experimenters lack these basic knowledge or have not paid enough attention to them; second, although there is a lot of trichlorethylene used in laboratory experiments, it is difficult to collect them together and send them to waste recycling station; third, the centralized treatment of these toxic substances will increase a lot of additional costs, and many units are unwilling to spend money
[0003] The trichlorethylene recovery device in the prior art has the problem that it is difficult to conveniently collect and separate the miscibles of asphalt and trichlorethylene, the waste of trichlorethylene is large, and it is easy to pollute the environment

Embodiment 1

[0045] figure 1 It is a structural schematic diagram of the trichlorethylene recovery unit 010 in Example 1 of the present invention; figure 2 yes figure 1 expanded view of image 3 yes figure 1 A view from direction A. See figure 1 , figure 2 , The trichlorethylene recovery unit 010 in this embodiment includes an open raw material container 100 for containing the trichlorethylene mixture Q1, a heating device 200 for heating the trichlorethylene mixture Q1, and a condensing device 300. The trichlorethylene mixture Q1 produced in the bitumen test mainly includes bitumen and trichlorethylene.

[0046] Wherein, the condensing device 300 includes a condensing plate 311 covering the opening of the raw material container 100 , and a deflector 320 opposite to the condensing plate 311 and located below the condensing plate 311 . The deflector 320 has an air flow port K1 communicating with the raw material container 100 and the lower end surface of the condensation plate 311 ....

Embodiment 2

[0054] This embodiment provides a trichlorethylene recovery method, which is based on the trichlorethylene recovery device 010 in the first embodiment. Please refer to the accompanying drawing ( Figure 1 to Figure 4 ), the trichlorethylene recovery method in the present embodiment may further comprise the steps:

[0055] Heating medium filling step: filling the heating medium container 210 with the heating medium Q3 so that the liquid level of the heating medium Q3 sticks to the bottom surface of the raw material container 100;

[0056] Trichlorethylene mixture addition step: add trichlorethylene mixture Q1 into the raw material container 100;

[0057] Heating step: use the heating device 200 to heat the trichlorethylene mixture Q1 in the raw material container 100 until the trichlorethylene in the trichlorethylene mixture Q1 gasifies and rises;

[0058] Condensation step: start the condensing device 300 to condense the vaporized trichlorethylene on the condensing plate 311...

Abstract

The invention relates to the technical field of trichloroethylene recovery, and aims at solving the problems that the trichloroethylene recovery devices in the prior art have difficulty in conveniently collecting and separating a miscible material of asphalt and trichloroethylene and are environment-hostile. The invention provides a trichloroethylene recovery device and a trichloroethylene recovery method. The trichloroethylene recovery device comprises a raw material vessel, a heating device and a condensing device, wherein the condensing device comprises a condensing plate and a guide plate, the condensing plate is covered above the opening of the raw material vessel, the guide plate is separately opposite to the condensing plate and positioned below the condensing plate; the guide plate is provided with a gas flow port communicating the raw material vessel with the lower end surface of the condensing plate; the guide plate is obliquely arranged; and the trichloroethylene recovery device is also provided with a liquid trichloroethylene delivery port. The trichloroethylene recovery device has the beneficial effects of treating and separating the miscible material of asphalt and trichloroethylene in time, utilizing trichloroethylene repeatedly many times, reducing experimental cost, and avoiding pollution of water and air due to disorderly emission.

Description

technical field [0001] The invention relates to the technical field of trichlorethylene recovery, in particular to a trichlorethylene recovery device. The invention also relates to a method for recovering trichlorethylene. Background technique [0002] Most of the high-grade highways in the world use asphalt pavement, because it has the following good properties: 1) Sufficient mechanical strength, able to withstand various forces imposed by vehicle loads on the road surface; 2) Certain elastic and plastic deformation capabilities, able to withstand 3) It has good adhesion to car tires, which can ensure driving safety; 4) It has a high degree of shock absorption, which can make the car run fast, stable and low noise; 5) It is not easy to raise dust, and it is easy to clean, Features such as flushing and repairing. Since the 1950s, the number of countries building asphalt pavements has grown rapidly, accounting for a large proportion. In my country, asphalt pavement is wide...
