Small and medium-sized boiling type quick-loading organic carrier heating furnace

Abstract

The invention discloses a feeding device, a furnace chamber, a waste heat device, a tail gas treatment device and a chimney which are connected in sequence; the lower part of the furnace chamber is a fuel combustion zone, which is connected with a quartz sand circulation system; the upper part of the furnace chamber is provided with a hot oil heater , which is connected with the oil inlet and outlet device through the oil pipe; the outlet of the hot oil heater is connected with the steam generator of the waste heat device, and the outlet of the steam generator is connected with the inlet of the air preheater; the steam generator and the steam pipeline are formed in the hot oil The fluidized bed circulation protection system between the heater and the fuel combustion zone; the tail gas treatment device includes a multi-tube dust collector and a circulation cleaning device connected in sequence. By connecting the furnace hearth, the waste heat device, the exhaust gas treatment device and the chimney in sequence, the invention can effectively precipitate the ash produced in the combustion process of the furnace chamber under the action of the waste heat device and the tail gas treatment device, and can also further reduce the heat emission temperature of the chimney and reduce the It can reduce the emission pollution produced by the heating furnace and is conducive to environmental protection.

Description

technical field [0001] The invention relates to a fast-loading heating furnace, in particular to a small and medium-sized boiling type fast-loading organic carrier heating furnace. Background technique [0002] The main function of the organic carrier heating furnace is to replace the hot blast furnace and the general steam furnace for heating in industrial production. The history of my country's heat transfer oil production began in the mid-1970s. So far, general industrial energy supply equipment is using organic carrier heating furnaces transformed from chain grates to achieve the required temperature for industry. With the advancement of heating furnace technology, my country has been able to produce heat-conducting oil heating furnaces ranging from 200,000 kcal to 30 million kcal, of which 90% are chain grate-based combustion methods, and the rest are manual feeding combustion methods. [0003] The use of heat conduction oil heating furnace can not be replaced by other...

AI Technical Summary

Problems solved by technology

[0003] The use of heat conduction oil heating furnace can not be replaced by other thermal energy equipment at present, but the chain grate has the problem that the fuel cannot be burned out, that is, the furnace has high oxygen content and high nitrogen oxide content. At the same time, the fuel cannot be burned completely and the thermal efficiency is low. , resulting in an increase in the production cost of the enterprise, and at the same time, its exhaust gas cannot meet the energy-saving and emission-reduction requirements advocated by the state; as my country's environmental protection requirements become higher and higher, and the implementation is becoming more and more strict, chain grate boilers are no longer suitable for my country's environmental protection and industrial production requirements
