Graining machine fuel gas hot air circular drying system and temperature control method thereof

Abstract

The invention relates to a graining machine fuel gas hot air circular drying system and a temperature control method thereof. The system comprises a hot blast stove. A natural gas combustor is arranged above the hot blast stove. An air inlet is formed in one side of the hot blast stove. An air outlet is formed in the bottom of the hot blast stove. The air outlet is connected with a main smoke pipe. The main smoke pipe is connected with a branch smoke pipe leading to a graining machine oven. The air inlet of the hot blast stove is connected with a wind return main pipe. An exhausting opening ofthe graining machine oven is connected with a wind return branch pipe communicating with the wind return main pipe. The graining machine fuel gas hot air circular drying system is simple in structure, low in wind resistance and high in operation flexibility, heat supply is stable, temperature distribution is uniform, and it is ensured that requirements of all working procedures of synthetic leather production can be met; and meanwhile, natural gas, smoke and mixed tail gas are directly used to serve as manners of heating the air, the heat loss is reduced in the heat supply process, the heat efficiency of the system is improved greatly, less equipment is needed, the working procedures are simple, and the original box body structure is modified little.

Description

technical field [0001] The invention relates to a heat supply technology in the production process of synthetic leather, in particular to a gas-fired hot air circulation drying system for a kneading machine and a temperature control method thereof. Background technique [0002] During the production process of synthetic leather, the air discharged from the oven of the continuous kneading machine has not been recovered reasonably, which increases fuel consumption and causes a certain amount of heat loss. [0003] At present, most of the heating methods used in domestic synthetic leather production are coal-fired heat-conducting oil furnaces for centralized heating. In the actual heating process, hot air is transported to the oven through long-distance air ducts, resulting in the temperature of the hot air entering the oven. Unstable, and the production of synthetic leather requires extremely high temperature stability, which requires a stable heating technology. Contents of...
