Detailed Description
The invention will be further described with reference to the accompanying drawings and specific examples:
implementation example 1:
in order to solve the problem that the explosion of a hearth is easy to occur in the conventional operation steps of the biomass energy curing barn, the embodiment adopts a biomass baking explosion-proof method, and referring to fig. 1, the method comprises the following steps:
firstly, mounting tobacco on kang technology, namely filling tobacco into a bulk curing barn, and closing a curing barn door, a cold air inlet door and a dehumidifying window of the curing barn;
secondly, switching on a power line of equipment, inserting a biomass fuel hopper baffle plate, and loading biomass fuel; the baffle plate of the biomass fuel hopper is inserted, so that the phenomenon that feeding is out of control due to misoperation of operators is prevented;
thirdly, powering on the host, opening the host case, placing a feeding motor button in a stop gear, and stopping feeding; putting the igniter button in a stop gear to stop ignition; putting a blower button in a stop gear to stop blowing; the rest buttons are arranged at the automatic positions; the function is to start the circulating fan to blow off tobacco leaves before ignition, and open the ventilation path;
fourthly, the circulating fan starts to work and plays a role in blowing off tobacco leaves, and opening an air path to enable the tobacco leaves to be dried everywhere;
fifthly, after the circulating fan runs for T minutes, a furnace door of the furnace is opened, so that the furnace is communicated with the outside, and the situation that the mixture of fuel and combustion air is accumulated in a closed narrow space to reach an explosion critical value and catches fire to generate deflagration is avoided; pulling out the baffle plate, and feeding the baffle plate by the hopper; opening a main case of the automatic control instrument, placing a feeding motor button in a manual gear to start feeding, and placing the feeding motor button in a stop gear to stop feeding when the feeding reaches m kilograms, wherein the automatic control instrument has the effect of manually controlling the feeding amount and avoiding deflagration caused by too high automatic feeding speed and excessive accumulated material ignition of equipment; putting the igniter button in an automatic gear to start ignition; putting the button of the blower in an automatic gear, starting blowing, stopping feeding ignition after the feeding quantity reaches the requirement, and ensuring ignition under the condition of less fuel without deflagration;
