Plasma hot-blast stove and gas recycling device based on plasma hot-blast stove

Abstract

The invention belongs to the technical field of heating equipment, and relates to a plasma hot-blast stove and a gas recycling device based on the plasma hot-blast stove. The plasma hot-blast stove comprises a stove body and plasma generators arranged on a stove body shell; the plasma generators communicate with an inner cavity of the stove body, and a temperature-adjusting gas source inlet and a hot air outlet are formed in the stove body; starting gas source inlets communicating with the inner cavity of the stove body are formed in the plasma generators; and the starting gas source inlets communicate with a starting gas source pipeline. The gas recycling device based on the plasma hot-blast stove comprises the plasma hot-blast stove and an industrial kiln. The industrial kiln is connected with the hot air outlet and is connected with the temperature-adjusting gas source inlet and the starting gas source inlets through a cooling and purifying device. The equipment is high in thermal power, high in output temperature and wide in gas source selection range, and the production cost is reduced; a production system is high in gas content and has recovery value; and the heat source temperature is controllable, gas is recycled, and resources are saved.

Description

technical field [0001] The invention belongs to the technical field of heating equipment, and relates to a plasma hot blast stove and a gas circulation recovery device based on the plasma hot blast stove. Background technique [0002] Hot blast stove, a thermal power machine, was widely used in our country in the late 1970s. It has become a replacement product for electrical sources and traditional steam power sources in many industries. There are many varieties and complete series of hot blast stoves, which are divided into two types: hand-fired and machine-fired according to the way of coal feeding, and divided into coal, oil, and gas stoves according to the type of fuel. [0003] The problems existing in the existing hot blast stoves are: (1) to generate a higher temperature, a large amount of fuel is required or multiple power equipments are used, resulting in many disadvantages such as waste of energy, excessive auxiliary equipment, and complicated process; (2) Existin...

Problems solved by technology

[0003] The problems existing in the existing hot blast stoves are: (1) to generate a higher temperature, a large amount of fuel is required or multiple power equipments are used, resulting in many disadvantages such as waste of energy, excessive auxiliary equipment, and complicated process; (2) Existing hot blast stove fuels provide relatively low power and temperature for the requirements of higher temperature drying or baking operations; at the same time, the existing hot blast stove fuels mostly use coal, oil, etc., to achieve The high-temperature gas source consumes more, the production cost is high, and the process gas produced is complex in composition, difficult to process, low in content, and difficult to recycle; (3) In actual production, the reaction temperature of different time periods or different processes may occur change, and the adjustment and control of the output temperature of the hot blast stove is difficult to control; (4) the existing gas stove has a large restriction on the gas, and the selection of the gas source is small
