pvc foam furnace heating system

Abstract

The invention relates to a PVC foaming furnace heating system in the field of heating equipment. The PVC foaming furnace heating system comprises a burning device, a combustion chamber, a buffering chamber, a shunting pipeline and a hot air blower, wherein the burning device is fixedly arranged on an access door of the foaming furnace and comprises a gas inlet pipe and a burner, and an opening of the burner is extended to the outside of the access door of the foaming furnace; and the shunting pipeline comprises a left shunting pipe and a right shunting pipe for uniformly shunting the heated gas in the buffering chamber, and the top parts of the left shunting pipe and the right shunting pipe are both in sealing connection with the bottom of the buffering chamber in a communicating manner. According to the heating system, the working environment of the burning device is gradually separated from the environment of the heating furnace to form a relatively independent working environment, based on the effective utilization of the heat energy, the security coefficient of the burning device burning in the foaming furnace is improved to the maximum extent; and a part of generated flue gas and heat can reenter another heating cycle of the burning device under the traction action of the hot air blower, and all heat energy can be effectively utilized.

Description

technical field [0001] The invention relates to the field of heat supply equipment, in particular to a heat supply system of a PVC foam furnace. Background technique [0002] Under the background that the country vigorously advocates energy conservation and environmental protection, energy conservation and environmental protection are the general trend of the country's future development. This year, all towns, districts and town governments issued a request for all boiler rectifications, requiring that all rectifications must be completed before the end of 2014, and coal-burning or biomass-burning boilers are not allowed to exist. [0003] Most of the heating devices of PVC foaming furnaces use coal boilers to heat and conduct oil to provide effective heat. This heating method is easy to pollute the environment and produce various particulate pollutants, and the heat is lost quickly and the combustion is uneven. It is difficult to meet the required heating requirements. In ...

[0003] Most of the heating devices of PVC foaming furnaces use coal boilers to heat and conduct oil to provide effective heat. This heating method is easy to pollute the environment and produce various particulate pollutants, and the heat is lost quickly and the combustion is uneven. It is difficult to meet the required heating requirements. In addition, in the traditional coal boiler heating method, the working environment of the burner is integrated with the working environment of the foaming furnace, resulting in a low overall safety factor and high creation, which cannot realize the cycle Heating, heat loss is serious, can not effectively make full use of all heat
