Abstract
The utility model discloses a kind of tunnel cave device, including kiln body, it is set to preheating section, reduction section, cooling section in kiln body successively from left to right, kiln body left end is provided with coal gas inlet pipe, cooling section is externally provided with combustion fan, heat exchanger, wherein for the air inlet of combustion fan with being connected in cooling section, the air outlet of combustion fan passes through pipeline bypass to coal gas inlet pipe by pipeline and the inlet communication of heat exchanger, the outlet of heat exchanger.The utility model directly obtains the air with certain temperature from cooling section as combustion air, it is not necessary to carries out extra preheating again, reduces energy consumption and cost, reduces production process.
Description
Technical field
Tunnel cave field is the utility model is related to, specifically a kind of tunnel cave device.
Background technology
Tunnel cave is the Thermal Equipment that the continous way of modernization is burnt till, and is widely used in the metallurgy industries such as abrasive material.Existing skill
, it is necessary to be equipped with heater when art ore abrasive material is processed using tunnel cave, heater is entered by the coal gas of pipeline and tunnel cave
Mouth connection, so that gas inlet introduces the combustion air with certain initial temperature, the tunnel cave of this structure need to be further provided with adding
Thermal, energy consumption and cost are higher.
Utility model content
The purpose of this utility model is to provide a kind of tunnel cave device, high to solve prior art tunnel cave energy consumption and cost
The problem of.
In order to achieve the above object, technical scheme is used by the utility model：
A kind of tunnel cave device, including kiln body, it is characterised in that：It is set to preheating section, reduction in kiln body successively from left to right
Section, cooling section, and preheating section, reduction section, cooling section are sequentially communicated, kiln body left end is provided with the coal gas inlet pipe led in preheating section,
Cooling section is externally provided with combustion fan, heat exchanger, and wherein with being connected in cooling section, combustion fan goes out the air inlet of combustion fan
Air port passes through pipeline bypass to coal gas inlet pipe by pipeline and the inlet communication of heat exchanger, the outlet of heat exchanger.
A kind of described tunnel cave device, it is characterised in that：The control circuit control that the combustion fan is made up of single-chip microcomputer
Make, temperature sensor is provided with cooling section, temperature sensor passes through the monolithic that data collecting card accesses combustion fan control circuit
Machine.
The utility model directly obtains the air with certain temperature from cooling section as combustion air, it is not necessary to carries out volume again
Outer preheating, reduces energy consumption and cost, reduces production process.
