Abstract

The invention relates to a heating device, in particular to a cold air surrounding type hot air decentralized heating device and aims to solve the problems that traditional heating modes arranged in a factory building are difficult to arrange, operating temperature of a working area is difficult to meet requirements and vertical temperature stratification occurs easily due to the fact that the factory building is large. The cold air surrounding type hot air decentralized heating device is characterized in that a first air inlet and a first air outlet are processed in the top surface and the bottom surface of a shell respectively, the top of a separating barrel is fixedly connected to the inner wall of the shell, the bottom of the separating barrel is fixedly connected to the bottom surface of the shell and communicated with the first air outlet, a plurality of air opening flow deflectors are arranged in the separating barrel, the outer wall of the separating barrel and the shell form a cyclone chamber, the sidewall of the shell is provided with a second air inlet, a fresh air pipeline outside the shell is communicated with the second air inlet, a fresh air fan is arranged in the fresh air pipeline, the bottom of the cyclone chamber is provided with a second air outlet, the wall of the separating barrel is provided with at least one reserved opening, and an air return bypass valve is arranged in each reserved opening. The cold air surrounding type hot air decentralized heating device is used for high space building heating.

Description

technical field [0001] The invention specifically relates to a cold wind surrounding type hot air dispersion heating device. Background technique [0002] At present, the commonly used heating methods for several tall spaces or workshops mainly include ordinary radiator heating, radiant heating and hot air heating. Due to the large building volume of tall factory buildings, it is difficult to arrange radiators, and the temperature in the working area is difficult to meet the requirements, which is prone to vertical temperature stratification; low-temperature floor radiation heating is not suitable for factories with complex ground conditions and heavy loads ; Medium and high temperature radiant heating is prone to thermal stratification, the temperature in the working area is low, the heating effect is not ideal, and it has certain dangers and limitations. However, for the currently existing hot air heating method, the energy consumption is generally large, and the energy s...
