Problems solved by technology

Its shortcomings are: 1. Due to the indirect heating method of air and heat medium, the equipment consumes a large amount of metal pipes to manufacture heat exchangers, which is expensive, and the maintenance rate of heat exchangers is high, and the service life is limited; 2. The power of the motor is large, and the cost High, energy consumption is high and there are safety hazards at the same time, and the hot air emitted by the equipment is dry and hot air, which is easy to blow up environmental dust, and the dust is large; 3. The angle of the air inlet and outlet is also difficult to adjust according to needs, etc.

Embodiment Construction

[0007] The present invention will be further described with reference to the accompanying drawings, but the present invention is not limited to the scope of the embodiments and the structures shown in the accompanying drawings.

[0008] The steam turbine heating machine of the present invention uses steam as power to drive the centrifugal impeller to rotate, and after the air is mixed with the steam, excess water is removed through a demister, and the heated air is blown out after entraining a small amount of water. The structure to realize the above functions includes an air inlet channel, a steam inlet pipe and a hot air outlet channel. Air and steam enter the mixing chamber through their respective pipes and mix. Steam nozzles are installed at the end of the steam inlet pipe inside the shell of the main engine. The steam nozzles are evenly distributed along the circumference of the steam inlet pipe. The outlet of the steam nozzles is in the shape of a long arc. The tangent ...

Abstract

The invention provides a turbine heater which comprises an air inlet passage, a steam inlet pipe and a hot air outlet passage. Air and steam enter a mixing chamber through corresponding pipelines to be mixed; the mixing chamber is positioned in a host housing; the air inlet passage is connected with the host housing in a sealing manner; steam spray nozzles are arranged at the end part of the steam inlet pipe, which is positioned in the host housing; the steam spray nozzles are uniformly distributed into a strip arc shape along the periphery of the steam inlet pipe; centrifuge blades are uniformly distributed on the peripheries of the steam spray nozzles; the tangential direction of each arc steam spray nozzle outlet passage is opposite to that of each arc centrifuge blade; a centrifugal impeller consisting of the centrifuge blades is connected with a rotating shaft by a fixing part; the maximum included angle alpha between the tangential direction of an outlet of each steam spray nozzle outlet passage and a string of each arc centrifuge blade is 90 degrees; and a demister is arranged in the host housing or in the hot air outlet passage. The turbine heater adopts steam as a heating source and a fan power source, enables the air to be directly heated, and does not require a heat exchanger and an electric motor so as to overcome the defects in the prior art.

Description

technical field [0001] The invention relates to mine wellhead antifreezing equipment, which is a steam turbine heater. Background technique [0002] At present, the equipment used for mine wellhead antifreeze is mainly heating equipment such as steam-type industrial heaters, steam-type air heaters or hot blast stoves. Blow it out and send it to the wellhead for antifreeze at the wellhead. Its shortcomings are: 1. Due to the indirect heating method of air and heat medium, the equipment consumes a large amount of metal pipes to manufacture heat exchangers, which is expensive, and the maintenance rate of heat exchangers is high, and the service life is limited; 2. The power of the motor is large, and the cost High, high energy consumption and potential safety hazards, and the hot air emitted by the equipment is dry and hot air, which is easy to blow up environmental dust, and the dust is large; 3. The angle of the air inlet and outlet is also difficult to adjust according to ...
