Abstract
The utility model discloses a directly-heated gas air heater, which comprises a heater body, a gas burner, an air distributing pipe, an air outlet pipe and a combustion chamber. The gas burner and the air distributed pipe are arranged on the lower portion of the heater body, the air outlet pipe is disposed on the top of the heater body, the combustion chamber is disposed at the bottom of a cavity of the heater body, a mixing stirring chamber is arranged in the middle of the cavity of the heater body, and the mixing stirring chamber consists of a plurality of S-shaped channels which are made of refractory bricks and arranged longitudinally. The directly-heated gas air heater has the advantages that by the aid of the technical scheme that the longitudinally-arranged S-shaped channels which are made of the refractory bricks are longitudinally arranged above the combustion chamber, the thickness of laminar flow is reduced according to a turbulence principle when high-temperature combustion gas in the cavity and air supplied by the air distributing pipe pass through the S-shaped channels, so that the air and flue gas are sufficiently mixed while advancing, mixing effect is greatly reinforced, and heat utilization efficiency is improved. In addition, the temperature of hot air discharged by the air outlet pipe is stable and reliable due to a heat storage function of the refractory bricks, and drying quality of products in a tunnel drying kiln is guaranteed.
Description
Technical field
The utility model relates to hot-blast stove, especially relates to the directly-heated type fuel gas hot-blast stove.
Background technology
The tunnel drying kiln is widely used in the processing of the drying of fire resistive material product, and its employed hot blast is many to be provided by the directly-heated type fuel gas hot-blast stove.Because directly-heated type fuel gas hot-blast stove when work gaseous fuel directly enters in the dry kiln after the air that the reacted high-temperature combustion gas of combustion chambers burn and gas-distribution pipe provide is mixed into a certain temperature, therefore, can high-temperature combustion gas fully mix with the air that gas-distribution pipe provides, and will directly influence the utilization rate of heat energy and the quality of hot blast.
Summary of the invention
The utility model purpose is to provide the directly-heated type fuel gas hot-blast stove that a kind of hot blast temperature is stable, the heat energy utilization rate is high.
For achieving the above object, the utility model can be taked following technical proposals:
Directly-heated type fuel gas hot-blast stove described in the utility model, it comprises body of heater, is arranged on the discharge pipe at fuel burner nozzle, aid distributing pipe and its top of described body of heater bottom, and the combustion chamber that is arranged on body of heater furnace chamber bottom; Be provided with the mixing teeter chamber at the middle part of body of heater furnace chamber, many S shape passages of described mixing teeter chamber for making by refractory brick, longitudinally be provided with.
The utility model advantage just is to take to be provided with many these technical schemes of S shape passage being made by refractory brick, longitudinally be provided with above described combustion chamber, therefore, the air that high-temperature combustion gas in the furnace chamber and gas-distribution pipe are supplied with is through S shape passage the time, according to turbulent principle, the laminar flow reduced thickness, make air and flue gas in advancing, be able to abundant mixing, strengthened mixed effect greatly, improved utilization efficiency of heat energy.Because the accumulation of heat effect of refractory brick is reliable and stable from the hot blast temperature that discharge pipe is discharged, guaranteed the dry mass of goods in the tunnel drying kiln simultaneously.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, directly-heated type fuel gas hot-blast stove described in the utility model, it comprises body of heater 1, is arranged on the discharge pipe 4 at fuel burner nozzle 2, aid distributing pipe 3 and its top of described body of heater 1 bottom, and the combustion chamber 5 that is arranged on body of heater 1 furnace chamber bottom; Be provided with the mixing teeter chamber at the middle part of body of heater 1 furnace chamber, many S shape passages 6 of described mixing teeter chamber for making by refractory brick, longitudinally be provided with.
