Curing system of intelligent clean energy intensive type curing barn and working method of curing system

Abstract

The invention discloses a curing system of an intelligent clean energy intensive type curing barn and a working method of the curing system. The curing system comprises a combustion heating chamber, acuring barn tobacco loading chamber, a combustion machine, a solar circulation fan, a ceiling temperature and humidity sensor, a bottom shed temperature and humidity sensor, a temperature and humidity controller, an electric floor window and an electric skylight; air in the combustion heating chamber is heated by the combustion machine, hot air is fed into the curing barn tobacco loading chamberthrough the solar circulation fan, circulated hot wind can quickly heat air in the curing barn tobacco loading chamber and make the air in the curing barn tobacco loading chamber flow quickly to forma dynamic heating environment, the occurrence of dry dead corners is avoided, the heat circulation is fast, not only can the heating rate of the curing barn tobacco loading chamber be increased, but also good temperature uniformity can be obtained, the curing effect is improved, and the quality of products is ensured. At the same time, the temperature and humidity controller can be used for flexibly monitoring and controlling the temperature and humidity in the curing barn tobacco loading chamber, the operation is simple and convenient, energy is saved, a cleaning effect is achieved, and the curing system and the working method are environmentally friendly.

Description

technical field [0001] The invention belongs to the technical field of barns, and in particular relates to an intelligent clean energy-intensive barn baking system and a working method thereof. Background technique [0002] After the tobacco leaves are ripe and picked, they must be roasted before they can be made into industrial tobacco. Curing is a key factor in determining the quality and usability of tobacco leaves. Advanced tobacco leaf curing equipment is the basis for accurately realizing the scientific curing process, improving the quality of tobacco leaves, and reducing labor intensity and production costs. [0003] The traditional intensive barn heating system includes furnace, heat exchanger, fan and other main equipment. Heat exchangers mostly adopt the form of pipes, and the main materials are steel pipes, refractory materials, ceramic tile pipes or cement sheets. The pipes are arranged in a "V" shape in the hot air chamber. The pipe diameter is generally betw...

AI Technical Summary

Problems solved by technology

The heat exchange tube made of steel pipe has a large thermal conductivity and high temperature resistance, but it has the disadvantage of being acidified and corroded by flue gas after long-term use

The heat exchange tubes made of refractory materials or ceramic tile tubes have high temperature resistance and simple interface, but have small thermal conductivity and low heat conversion efficiency, which is not conducive to energy saving

In addition, the traditional heat exchange tubes in the hot air chamber need to be arranged horizontally or vertically, with 2 to 3 rows on the left and right, and 2 or 3 layers up and down. higher requirements

That is, the drying function is realized by heating the heat exchange tube. The heating time is long and the drying efficiency is poor. The baking process generally takes more than 100 hours.

Moreover, the firepower of the combustion chamber of the baking room is completely controlled manually, and the temperature and humidity of the baking room are monitored, so the labor intensity is very high, and it is difficult to control the temperature and humidity of the baking room, and it is impossible to accurately time the entire baking process. The utilization rate of the tobacco leaf industry is low, and the heating equipment uses coal combustion for heat supply, which consumes a lot of energy and produces dust that pollutes the environment and affects the quality of tobacco leaves.
