High temperature mass transfer purification tower
After the pyrolysis reactor is fed with raw materials and is heated, that will produce pyrolysis gases. The generated gas flows to the cooler. The pyrolysis gas contains a large amount of slag, and the fuel oil after being cold also contains some slag. This kind of oil is usually called “crude oil”. The crude oil also needs secondary cracking and refining, which wastes a lot of heat energy, increases energy consumption, takes up manpower, and need more investment, pollutes the environment, affects normal production, and often blocks the ventilation system, which is extremely unsafe.
The technical problem to be solved by the out patent technology, which is to provide a tower type high-temperature mass transfer purifier to realize the capture of slag in the system, the further purification and cooling of gas and the collection of heavy oil. In order to solve the above technical problems, the technical scheme is as follows: the tower type high temperature mass transfer purifier includes a gas-liquid purification chamber, a heating device connected with the gas-liquid purification room, a high-temperature liquid level automatic alarm is connected with the heating device, and the upper part of the gas-liquid purification chamber is connected with a shutter, a packing device, an arc-shaped tower plate and a fractionation section in turn, and between the packing device and the arc-shaped tray There is a heavy oil collecting chamber outlet, and an gas outlet is arranged at the upper part of the fractionation section. As the preferred scheme, the heating device uses electric heating or heat transfer oil heating or high temperature flue gas heating.
To realize the above technical scheme, the technical effect of this technology is as follows: the slag of pyrolysis gases is further captured, and the loss of heat energy is saved under the action of micro negative pressure. Through the tower type high-temperature mass transfer purification device, the crude oil does not need secondary fine feeding, and the light part of the gas enters the follow-up section for cooling and oil collection from the gas outlet, thus the oil quality is further improved. The color and smell is significantly improved, which saves a lot of manpower and investment, reduces production links, reduces production costs, and saves energy, environmental protection and safety. The working principle and process of the utility model are as follows: after heating the pyrolysis reactor, the feedstock raw materials inside the pyrolysisr reactor will generate pyrolysis gases. The generated pyrolysis gas enters the gas-liquid purification chamber in the tower type high-temperature mass transfer purifier, In the gas-liquid purification room, mass transfer, purification and separation, optimization matching, gas-liquid contact mass transfer, driven by the heat energy conversion of the heating device, the gas is fully purified and gasified in the high-temperature liquid, and the slag is captured ideally. The gasified gas is purified through the gas-liquid purification chamber, louver and packing device, and the purified gas passes through the arc-shaped tray, After entering the fractionation section, the heavy oil is collected through the outlet of the heavy oil collection chamber, and then flows into the follow-up section for treatment; while the light component gas in the upper part of the fractionation section flows from the top outlet to the subsequent section for process treatment, and finally completes the gas purification and slag capture, which improves the oil quality and effectively separates and collects the heavy oil and light oil. The high temperature liquid level automatic alarm has advanced technology and clear display, which can provide the liquid volume in the device in time. It is safe and reliable. It can timely grasp the liquid level and oil level, timely adjust the heat source, fully gasify and thoroughly remove slag.
