Abstract
The invention discloses a kind of closed circuit blower heating systems, including heating container and air blower, it heats container and is equipped with air inlet and air outlet, the air outlet of the air inlet and air blower that heat container is connected by admission line, and the air inlet of the gas outlet and air blower of heating container is connected by outlet pipe；Gas recycles in the closed circuit that air blower, admission line, heating container and outlet pipe are formed, and when gas passes through air blower, gas is heated up by compression, then flows into heating container, and gas temperature rises after a circulation process；So circulation, temperature stablizes rising after gas flows through air blower, until reaching heating container required temperature.The needs of present invention can guarantee the stabilization of gas heating system heating or insulating process, meet user to heating container continuous heating and keep constant temperature.
Description
Technical field
The present invention relates to gas heating system technical field more particularly to a kind of closed circuit blower heating systems.
Background technique
Gas heating system mainly uses resistance wire to be heated at present, such heating method low efficiency, heating temperature
Jumping characteristic is big, and heating temperature is unstable.And for needing the stable working condition risen and reach steady temperature of temperature, it is existing
Resistance wire type heating system is unable to meet demand.
Summary of the invention
The present invention in view of the deficiencies of the prior art, provides a kind of closed circuit blower heating system, guarantees that gas adds
The stabilization of hot systems heating or insulating process.
In order to solve the above technical problems, the present invention adopts the following technical scheme that：Closed circuit blower heating system, including add
Heat container and air blower, heating container are equipped with air inlet and air outlet, heat the air inlet of container and the air outlet of air blower
It is connected by admission line, the air inlet of the gas outlet and air blower of heating container is connected by outlet pipe；
Gas recycles in the closed circuit that air blower, admission line, heating container and outlet pipe are formed, when gas passes through drum
When blower, gas is heated up by compression, then flows into heating container, and gas temperature rises after a circulation process；So circulation, gas
Temperature stablizes rising after body flows through air blower, until reaching heating container required temperature.
Expansion joint, safety valve and regulating valve are equipped on the admission line and outlet pipe.
Blow valve is also connected on the heating container.
It further includes matched control and detection system, and control includes control module with detection system and holds set on heating
The signal input part of temperature sensor in device, temperature sensor and control module controls connection, the signal output of control module
End is connect with the air compressor control.
The air blower is frequency conversion air blower.
The beneficial effects of the invention are as follows：
The heating container for needing to heat and keep constant temperature in the present invention connect shape with air blower by admission line and outlet pipe
At closed circuit, gas recycles in the closed circuit（When system starts, heating gas temperature in container is room temperature）, work as gas
When passing through air blower, gas is heated up by compression, then flows into heating container, and gas temperature rises after a circulation process；So
Circulation, temperature stablizes rising after gas flows through air blower, until reaching heating container required temperature, to realize gas heating
The stabilization of system heating.After reaching heating container required temperature, adjusting air blower operating condition makes air blower run shaft power
Equal to system radiating power, that is, it can guarantee that heating vessel temp is constant.
Detailed description of the invention
Fig. 1 is systematic schematic diagram of the invention.
Specific embodiment
It elaborates below in conjunction with attached drawing to a specific embodiment of the invention.
As shown in Figure 1, closed circuit blower heating system of the invention, including heating container 6 and air blower 1, heating are held
Device 6 is equipped with air inlet and air outlet, and the air inlet for heating container 6 is connect with the air outlet of air blower 1 by admission line 2,
The gas outlet for heating container 6 is connect with the air inlet of air blower 1 by outlet pipe 8.
In the present embodiment, expansion joint 3, safety valve 4 and regulating valve are equipped on the admission line 2 and outlet pipe 8
5, and heat and be also connected with blow valve 7 on container 6.The setting of expansion joint 3 can compensate pipeline thermal deformation, prevent from damaging
Blower.The setting of regulating valve 5 is to adjust the gas flow in closed circuit.
Closed circuit blower heating system of the invention further includes matched control and detection system, control and detection system
It may also set up temperature including control module and in the temperature sensor heated in container 6, admission line 2 and outlet pipe 8
Spend sensor, the signal input part of above-mentioned temperature sensor and control module, which controls, to be connected, the signal output end of control module with
The control of air blower 1 connection, to adjust air blower operating condition.In the present embodiment, air blower 1 selects frequency conversion air blower.
When system starts, heating gas temperature in container 6 is room temperature, and gas is in air blower 1, admission line 2, heating container
6 and outlet pipe 8 formed closed circuit in circulation, when gas pass through air blower 1 when, gas by compression heat up, then flow into
Container 6 is heated, gas temperature rises after a circulation process；So circulation, temperature stablizes rising after gas flows through air blower 1,
Until reaching heating 6 required temperature of container, to realize the stabilization of gas heating system heating.
After reaching heating 6 required temperature of container, control and detection system pass through frequency conversion according to the signal of temperature sensor
Speed governing blast blower 1 adjusts 1 operating condition of air blower, so that air blower operation shaft power is equal to system radiating power, that is, can guarantee and add
Heat container temperature is constant.
In the prior art, the gas heating of air blower output at runtime is its counter productive, will be use up in production practices
Amount avoids gas heating, or even setting cooler from carrying out cooling operation to elevated temperature gas.And the present invention it is Promethean utilize air blast
Machine compressed gas is heated, while using closed circulation system, is realized gas uniform speed heating in heating container, is guaranteed that gas adds
The needs of hot systems heating or insulating process are stablized, and meet user to heating container continuous heating and keep constant temperature.
The above embodiments are only used to illustrate and not limit the technical solutions of the present invention, although referring to above-described embodiment to this hair
It is bright to be described in detail, those skilled in the art should understand that：Still the present invention can be modified or be waited
With replacement, without departing from the spirit or scope of the invention, or any substitutions, should all cover in power of the invention
In sharp claimed range.
