Ceramic kiln in the use of the process of high energy consumption, high resource consumption, serious environmental pollution and other problems are the current ceramic industry development of serious problems.Kiln combustion exhaust gas pollution types mainly include: SO2, NOx, CO, particulate matter, lead, cadmium, nickel and its compounds, fluoride and chloride and so on, and the traditional kiln direct emissions into the atmosphere, causing serious pollution to the environment, the need to have reliable purification treatment devices to meet emissions requirements, but the original purification plant purification effect is poor, process complex aspects of problems.This paper introduces a new porous ceramic purification device to improve the electric kiln exhaust gas purification to improve the catalytic conversion of CO, NOX, SO2 desulfurization and particulate matter purification.
The lead-free wood leafhopper is the iconic traditional ceramic art of the Jizhou kiln in the Song Dynasty of China. The traditional lead-free wood leafhopper is usually made of black glaze. The glaze is placed on the mulberry leaf and fired at a high temperature of about 1230 °C-1260 °C. And the veins are clear. Jizhou kiln was founded in the late Tang Dynasty. It flourished in the Five Dynasties and Northern Song Dynasty. It was the most prosperous in the Southern Song Dynasty. It began to decline in the late Yuan Dynasty and then stopped for more than 700 years. However, its unique artistic value has gradually be attracted the attention by the world. And it recovered in 1985 at last after unremitting efforts. The re-burning of the lead-free wood leafhopper has successfully opened the ceramic market of the lead-free wood leafhopper and made it occupy a certain position in the ceramic market. The price of lead-free wood leafhopper has remained high, and therefore ceramic producers are waiting for opportunities to produce on a large scale in order to achieve huge economic benefits. However, due to the great difficulty in the firing process of the lead-free wood leafhopper, the market has a phenomenon of low yield, high price, low consumer desire, and the use of chemical materials to fire products. The subject analyzed and solved these phenomena through a large number of experiments. Lead-free in this subject is a relatively broad definition, especially referring to the new type of lead-free wood leafhopper without contain heavy metals.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
