Tobacco baking room achieving full utilization of heat energy

Abstract

The invention discloses a tobacco baking room achieving full utilization of heat energy, and belongs to the technical field of tobacco baking facilities. The tobacco baking room comprises a heat supply chamber and a tobacco baking chamber which communicates with the heat supply chamber, wherein a heat exchanger, a dust removal box and a purifying device are arranged in the heat supply chamber; thedust removal box and the purifying device are arranged at the bottom of the heat supply chamber; a smoke fire inlet, which communicates with a smoke fire channel of a combustion furnace, is formed inthe outer end of the heat supply chamber; an inlet of the heat exchange communicates with the tail end of a heat collection drum; the front end of the heat collection drum communicates with the smokefire inlet, and a smoke outlet of the heat exchanger communicates with the inlet of the dust removal box or a chimney via a three-way valve and a pipeline; the inlet of the purifying device communicates with the outlet of the dust removal box; the purifying device is composed of a medium-efficiency filter layer, a high-pressure electronic dust collector and an activated carbon honeycombed filterlayer which sequentially communicate with each other; and the outlet of the purifying device communicates with an inner cavity of the heat supply chamber and is provided with an airflow control valve.According to the tobacco baking room provided by the invention, dust in smoke is removed via the tail gas purifying device, and the smoke is recycled to bake tobacco after harmful gas is adsorbed; therefore, the tobacco baking room has the characteristics of achieving full utilization of heat energy, avoiding pollution, reducing energy consumption and the like.

Description

technical field [0001] The invention relates to a tobacco leaf drying device, in particular to a tobacco leaf curing barn which fully utilizes heat energy, and belongs to the technical field of tobacco leaf drying facilities. Background technique [0002] In recent years, with the promotion of circular economy and sustainable development strategy, the awareness of green environmental protection has been enhanced, and waste biomass energy has been widely used. In particular, the wide application in the flue-cured tobacco industry has also made great progress, but the traditional biomass curing room uses the heat generated by burning biomass to heat the heat exchanger and circulate the hot air through the circulation fan to dry the tobacco leaves. The exhaust gas and waste heat after passing through the heat exchanger are directly discharged into the air through the chimney, which not only pollutes the environment, but also wastes heat energy. According to estimates, the disch...

Problems solved by technology

[0003] The technical problem to be solved by the present invention is to provide a tobacco barn that fully utilizes heat energy in view of the existing problems of insufficient heat energy utilization and environmental pollution in the prior art. By configuring a flue gas purification system, the flue gas after heat exchange is dedusted and adsorbed. SO 2 , NO 2 Wait for the harmful gas to be reused for tobacco leaf curing to reduce the energy consumption and emissions of flue-cured tobacco
