Odor-free drying device

Abstract

The invention relates to a drying device without odor dispersing. The drying device without odor dispersing comprises a heat-accumulating type hot blast stove and a drier, wherein the heat-accumulating type hot blast stove comprises two heat accumulating chambers communicated with each other, and the gas flow direction in the two heat accumulating chambers is controlled by four air stops valves; the upper parts of the two heat accumulating chambers are communicated, the heat accumulating chambers require replenishing air or hot air; heat accumulating material is arranged in the heat accumulating chambers; the drier comprises a material inlet, a drying chamber, a material outlet, a water spraying dust removal mechanism and a gas exhaust port; the gas inlet of the heat-accumulating type hot blast stove is communicated with the gas exhaust port of the drier, the gas outlet of the heat-accumulating type hot blast stove is divided into two branches, one branch is connected to the gas inlet of the drier, and the other branch is used for gas emptying. With the adoption of the heat-accumulating type hot blast stove, repugnant substance contained in gas is sufficiently oxidized into scentless substance under high temperature, and the exhaust gas can be emptied or used for dehumidification of a dehumidifier.

Description

technical field [0001] The invention relates to a drying device, in particular to a drying device without odor emission. Background technique [0002] Feed and organic fertilizers will emit a certain amount of waste gas during the drying process. At the same time, there is an odor in the waste gas. These waste gases are directly discharged into the atmosphere, causing serious environmental pollution. For example, the main process of organic fertilizer production includes composting and drying. The important potential odor substances produced in the composting process mainly include fatty acids, amines, aromatic and cyclic compounds, inorganic sulfides, organic sulfides, terpenes, and ammonia. And others, these substances produced in the composting process, when heated and dried, will be discharged into the atmosphere with the dry waste gas to pollute the environment. For example, ammonia (NH3) emitted during the drying of organic fertilizers is the main compound in the odor...

Problems solved by technology

figure 1 Middle 1-6 is the discharge mechanism, in which the dried material is separated from the dry gas, the dried material is discharged from the bottom to the container 1-11 for the finished product, and the gas enters the dry ash removal device 1-7 ; figure 1 1-8 is the water spray ash removal mechanism. The functions of the reform mechanism include two. First, use water spray to remove particulate matter in the air. Second, use the direct contact between water and exhaust gas to cool the exhaust gas, and at the same time make Condensation of moisture in the exhaust gas; figure 1 Among them, 1-9 are exhaust gas exhaust fans, and all dry exhaust gas is discharged to the atmosphere from 1-9. figure 1 Middle 1-12 is the spray water pump, because the water spray cannot completely eliminate the stench in the exhaust gas
