Abstract
An air inlet system of a trolley type gas heat treatment furnace comprises an air inlet tube, an air blower, a preheating chamber and an air supply tube. The air inlet tube is communicated with an air inlet of the air blower, an air filter is installed in the air inlet tube, an air outlet of the air blower is communicated with the preheating chamber, an outlet of the preheating chamber is communicated with the air inlet tube, and a high-temperature tail gas inlet and a high-temperature tail gas outlet are respectively installed on the preheating chamber and respectively located at two ends of the preheating chamber. The high-temperature tail gas inlet is communicated with the tail gas outlet of a heat treatment furnace combustion chamber. The air inlet system of the trolley type gas heat treatment furnace leads high-temperature tail gas inside the heat treatment furnace into the preheating chamber so as to preheat air to be led into the combustion chamber. Therefore, the tail gas can be further utilized fully before discharged to the atmosphere, and the combustion effect of the combustion chamber is good after the air to be led into the combustion chamber is preheated.
Description
Technical field
The present invention relates to a kind of car-type combustion gas heat-treatment furnace air inlet system.
Background technology
Heat-treatment furnace is the general designation of metal works being carried out the industrial furnace of various metal heat treatmets.Heat-treatment furnace can adopt the type of furnace of various heating furnaces, but requires more strictly to control furnace temperature and furnace atmosphere etc.The most using gases fuel heating of heat-treatment furnace, in order accurately to control furnace temperature, the heat-treatment furnace that has is used electrical heating.Modern heat treatment (particularly thermo-chemical treatment) technology is increasingly sophisticated, and the form of heat-treatment furnace is also a lot.For continuous heat treatment flow process, must be equipped with suitable continuous heat treating furnace; For cycling Technology for Heating Processing, operating machine and the automation that adopt the controlled atmospher of forced circulation and make stove.
Like the patent No. 200720040085 disclosed a kind of heat-treatment furnace structures, purpose provides the less heat-treatment furnace of a kind of floor space.It comprises solid solution stove, the aging furnace that is provided with roller bar type transport; Quenching tank; And material is transported to the grass-hopper of aging furnace from the solid solution stove through quenching tank, solid solution stove, aging furnace are arranged up and down, and liftable grass-hopper is set below the end of solid solution stove; On the bottom surface of the solid solution stove above the grass-hopper, have with bottom surface and become the split type movable discharge door that is connected; The below of grass-hopper is a quenching tank; One side of quenching tank is an aging furnace; Roller bar type transport is set on grass-hopper, and the roller rod on grass-hopper, solid solution stove, the aging furnace parallels.
This patent is not improved the air inlet system of heat-treatment furnace.Because the combustion gas heat-treatment furnace needs the gas-firing heat supply, whether natural gas can fully burn, and the temperature of control whether can be stable burning, directly has influence on the thermal effectiveness of heat-treatment furnace.Know according to the applicant; The air inlet system of prior art directly utilizes air blast that air outside is flowed to the combustion chamber through passage; The air of outside mostly is the relatively low cryogenic gas of temperature, need the air of low temperature be heated in the process of fuel gas buring, causes certain energy waste.And in the process that heat-treatment furnace uses, generally the tail gas after the burning is seldom utilized, so also cause the loss of the heat energy of tail gas the inside.
Summary of the invention
The objective of the invention is to overcome the shortcoming of above-mentioned prior art, the car-type combustion gas heat-treatment furnace air inlet system that provides a kind of heat energy that utilizes combustion tail gas the inside air intake duct to be carried out preheating.
The objective of the invention is to realize through following technical scheme:
A kind of car-type combustion gas heat-treatment furnace air inlet system; Comprise air inlet pipe, air blast, preheating chamber and air supply pipe, said air inlet pipe is communicated with the air inlet of air blast, and air cleaner is installed in air inlet pipe; The gas outlet of said air blast is communicated with preheating chamber; The outlet of said preheating chamber is communicated with air supply pipe, on said preheating chamber, is separately installed with high-temperature tail gas inlet and high-temperature tail gas outlet, and said high-temperature tail gas inlet and high-temperature tail gas outlet lay respectively at the two ends of preheating chamber.
Said high-temperature tail gas inlet is communicated with the tail gas outlet of heat-treatment furnace combustion chamber.
Car-type combustion gas heat-treatment furnace air inlet system of the present invention imports in the preheating chamber through the high-temperature tail gas that heat-treatment furnace is inner, and the air before the entering combustion chamber is carried out preheating.Can make tail gas carry out a step before in being discharged into atmosphere like this and utilize fully, and after getting into air before the combustion chamber and carrying out preheating, can make the combustion efficiency of combustion chamber better.
Description of drawings
According to accompanying drawing and embodiment the present invention is done further explain below.
Fig. 1 is the structure chart of car-type combustion gas heat-treatment furnace air inlet system according to the invention.
The specific embodiment
As shown in Figure 1; The described car-type combustion gas of embodiment of the invention heat-treatment furnace air inlet system; Comprise air inlet pipe 1, air blast 2, preheating chamber 3 and air supply pipe 4, said air inlet pipe 1 is communicated with the air inlet of air blast 2, in air inlet pipe 1, air cleaner is installed; The gas outlet of said air blast 2 is communicated with preheating chamber 3; The outlet of said preheating chamber 3 is communicated with air supply pipe 4, on said preheating chamber 3, is separately installed with high-temperature tail gas inlet 5 and high-temperature tail gas outlet 6, and said high-temperature tail gas inlet 5 and high-temperature tail gas outlet 6 lay respectively at the two ends of preheating chamber.
Said high-temperature tail gas inlet 5 is communicated with the tail gas outlet (not shown) of heat-treatment furnace combustion chamber.
Car-type combustion gas heat-treatment furnace air inlet system of the present invention imports in the preheating chamber through the high-temperature tail gas that heat-treatment furnace is inner, and the air before the entering combustion chamber is carried out preheating.Can make tail gas carry out a step before in being discharged into atmosphere like this and utilize fully, and after getting into air before the combustion chamber and carrying out preheating, can make the combustion efficiency of combustion chamber better.
