Embodiment Construction
[0052] like figure 1 As shown, a SiC synthesis furnace gas collection system, the gas collection system includes a collection device 12 placed on the SiC synthesis furnace for gas collection, a clutch walking mechanism 1 connected to the collection device 12, arranged on the collection device The detection and analysis device and equalizing pressure relief device on 12 are arranged around the furnace body 3 of the SiC synthesis furnace and are in contact with the collection device 12 to form a sealed connection device that forms a closed space.
[0053] Collection device 12: including collection case 2 and sealing skirt 18, rails 16 are installed on both sides of the SiC synthesis furnace, wheels 15 are installed on the lower ends of both sides of the collection case 2, so that the collection case 2 reciprocates on the rails 16, and the collection case 2. A sealing skirt 18 is arranged at the lower end, and the sealing skirt 18 is closely connected with the collecting case 2. ...

The invention relates to a SiC synthetic furnace gas gathering system and a gas gathering method, wherein the gas gathering system comprises a gathering device used to gather gas and positioned on the SiC synthetic furnace, a clutch travelling mechanism used to move the gathering device, a detection analysis device arranged on the gathering device, an equilibrium pressure relief device arranged on the gathering device, a sealing and connecting device arranged around the furnace body of the SiC synthetic furnace, contacted with the gathering device to form a enclosed space, and a gas outlet arranged on the sealing and connecting device and / or the gathering device. The steps of the gas gathering method of the SiC synthetic furnace are as follows: materials are mixed and filled in the SiC synthetic furnace; the gathering device is placed at the designated position and sealed; air is exchanged; the carborundum is produced; the CO gas is gathered; the power is cut to cool; the gas gathering is delayed; the furnace gas is exchanged; and then the gathering device is shifted out. The SiC synthetic furnace gas gathering system and the gas gathering method are beneficial for the sustaining and steady recovery of the SiC synthetic furnace gas. The SiC synthetic furnace gas gathering system has small occupation space and lower demands for the production site, and can meet the outdoor and indoor production requirements at the same time.
Description
technical field [0001] The invention relates to a gas collection system and a gas collection method, in particular to a SiC synthesis furnace gas collection system and a gas collection method. Background technique [0002] While producing SiC, a large number of by-products—a gas with CO as the main component—are produced, hereinafter referred to as SiC furnace gas. The gas has the characteristics of large output (about 1.4 tons of CO gas produced from 1 ton of SiC), high purity (CO content can reach 96%), and stable gas volume (little change with smelting time). Due to various factors such as cognition level, technical status and investment barriers, it is burned as waste gas in industrial production, and CO 2 Greenhouse gases are released into the atmosphere. Obviously, burning and discharging the gas will not only pay a large environmental price, but also waste the easily available energy that can be used. Studies have shown that after simple purification process, it ca...
