Safety and high-efficiency biomass energy hothouse system

Abstract

The invention discloses a safety and high-efficiency biomass energy hothouse system. The system has a biomass boiler. A dry type induced draft dust collector of the biomass boiler is connected with a wet flue gas exhauster. A water chamber of the biomass boiler is connected with a surface cooler of a cabinet fan through a water outlet pipe equipped with a hot water circulating pump, and a water return pipe connects the surface cooler to the water chamber of the biomass boiler. An air supply outlet of the cabinet fan is connected to a hothouse, the cabinet fan is also connected with the hothouse through a centrifugal fan via an air return port, and the centrifugal fan is driven to operate by an explosion-proof motor through a transmission belt. Under the control of an automatic operation control system, the circulating pump pumps hot water to the surface cooler of the cabinet fan, the hot water exchanges heat with air exhausted from the hothouse by the centrifugal fan, and the heated air returns to the hothouse to make a temperature of the hothouse rise to the desired temperature. The invention adopts high-compression biomass particles as fuel, which has high combustion heat value, is not affected by environment, and has environmental friendliness and good economic benefit. An air circulation channel between the cabinet fan and the hothouse is free of electrical contacts, and is safe and reliable.

Description

technical field [0001] The invention relates to a safe and high-efficiency biomass energy barn system, in particular to a biomass energy safe and high-efficiency barn system for drying fireworks and firecrackers. Background technique [0002] Biomass energy refers to a kind of energy produced by the combustion of biomass particles at present. Biomass particles are made of combustible particles by using waste straw, sawdust and other biomass raw materials through drying and extrusion processes. The advantages are: 1. . Because it is highly compressed biomass pellets, the calorific value of combustion is high and stable. The raw material agricultural and forestry waste used is a renewable energy source, which belongs to the category of circular economy and is supported by national policies; 2. The content of sulfur and nitrogen is extremely low, and the combustion The final sulfur dioxide emission is close to zero, which is quite environmentally friendly. The current biomass ...

Problems solved by technology

[0003] The traditional drying room for fireworks and firecrackers uses high-temperature water vapor generated by a coal-fired boiler to be transported to the radiator in the drying room through pipes. Because the boiler itself is highly dangerous, in order to ensure safe production, the boiler is set far away from the drying room. The pipeline is long, and the high-temperature steam loses a lot of heat before entering the radiator, which makes the energy utilization rate low. At the same time, because the boiler uses coal-fired heating, the cinder and exhaust gas produced by it pollute the environment and are not conducive to environmental protection.

[0004] In recent years, there have been firework and firecracker drug drying barns with air-source heat pumps as heat sources. Air-source heat pumps absorb low-grade heat energy in the natural air through the conduction medium and upgrade it to usable high-grade heat energy for use. Although the environmental protection effect is good , but on the one hand, the initial investment cost is high, and because the system needs to defrost repeatedly when the natural temperature is low, the defrosting process not only consumes unnecessary power, but also cools down the barn, so the heating effect of the air source heat pump is poor, and the heat energy provided is insufficient In order to effectively meet the needs of the drying barn for fireworks and firecrackers, this barn needs to be equipped with an electric auxiliary heating auxiliary device in the circulating air duct at the same time, and its economic benefits are not ideal; at the same time, the air source barn heating cabinet adopts a built-in axial fan It is completely exposed in the circulating heating air duct. Since the air duct is high temperature and the baked medicine is rich in corrosive substances such as sulfur and phosphorus, it is very easy to corrode the wiring electrodes of the electric auxiliary and axial flow fans, and it is possible that the wiring posts of the two will be damaged during startup. And arc sparks are generated during operation, so there are certain safety hazards
