Environmental protection and energy saving multi-purpose furnace

Abstract

The invention relates to an environmental protection and energy saving multi-purpose furnace which comprises a furnace body. The furnace body is internally provided with a burning chamber and a watertank layer surrounding the burning chamber; the burning chamber is provided with a first heat exchanger and a feeding opening, and the water tank layer is provided with the water inlet end and the water outlet end communicating with the first heat exchanger; and the furnace body is further provided with a hot air chamber arranged in the water tank layer and communicating with the bottom of the burning chamber, the hot air chamber is provided with a second heat exchanger and an air outlet channel, the second heat exchanger communicates with the first heat exchanger and the water tank layer, andthe air outlet channel is provided with a sucking pump in a connected manner. The environmental protection and energy saving multi-purpose furnace is high in using safety factor and wide in applicability; in addition, the structure arrangement of the multi-purpose furnace enables burning of the fuel to be more sufficient, and energy conservation and environment protection are better achieved in use; the multi-purpose furnace can provide hot air and hot water at the same time, the energy using rate of the fuel is further improved; and the multi-purpose furnace directly heats air, the generatedhot air is light, the corresponding conveying equipment requirement is low, the equipment maintaining requirement is low, and the production and using cost is effectively reduced.

Description

technical field [0001] The invention relates to a stove mainly for generating hot gas, in particular to an environment-friendly and energy-saving multipurpose stove. Background technique [0002] Hot air in industrial production and domestic heating is often produced by heating water with boilers. The technology of obtaining hot air in this way has the following problems: First, because the boiler heating temperature is very high, the steam pressure in the boiler will be very high. This often leads to boiler explosions and casualties, and there are great potential safety hazards, and there are relevant regulations that personnel who have not undergone strict training are not allowed to work on the boiler, which has high requirements for operators; third, during the heating process of the boiler, A large amount of heat energy generated by fuel cannot be used, and the energy utilization rate is relatively low; second, boilers using fuel to heat will produce a large amount of h...

[0002] Hot air in industrial production and domestic heating is often produced by heating water with boilers. The technology of obtaining hot air in this way has the following problems: First, because the boiler heating temperature is very high, the steam pressure in the boiler will be very high. This often leads to boiler explosions and casualties, and there are great potential safety hazards, and there are relevant regulations that personnel who have not undergone strict training are not allowed to work on the boiler, which has high requirements for operators; third, during the heating process of the boiler, A large amount of heat energy generated by fuel cannot be used, and the energy utilization rate is relatively low; second, boilers using fuel to heat will produce a large amount of harmful gases including sulfur dioxide and black smoke, causing great pollution to the environment; fourth, steam in The heat loss in the transportation process is extremely high, and the quality requirements for the transportation equipment are usually high and the cost is high; in addition, the quality of the steam is also relatively large, and the water vapor condenses into water, and a certain amount of liquid water will accumulate in the transportation pipeline, which is not conducive to steam delivery

[0003] The invention provides an environment-friendly and energy-saving multi-purpose furnace to overcome the problems existing in most existing boilers, such as large safety hazards, insufficient energy utilization, serious environmental pollution, large transmission heat loss, high equipment requirements, high production and transportation costs, etc.
