Description

TECHNICAL FIELD

[0001] The present application relates to the field of steam generator, in particular, a waste heat steam generator. BACKGROUND

[0002] The boiler is a mechanical equipment which uses the heat energy of fuel or other energy to heat water into hot water or steam. The hot water or steam produced by the boiler can directly provide the required heat energy for industrial production and people's life. The boiler which produces steam is called steam boiler. The steam boiler directly heats by using fuel or other energy. The energy consumption is high. The flue gas produced by heating is not recycled and utilized, which greatly wastes energy and is not conducive to the steam production efficiency. CONTENT OF THE UTILITY MODEL

[0003] The summary part of the present application is used to introduce the concept in a brief form. The concept will be described in detail in the specific embodiment part. The summary part of the present application is not intended to identify the key features or essential features of the claimed technical solution, nor is it intended to limit the scope of the claimed technical solution.

[0004] In order to solve the technical problems mentioned in the background part, some embodiments of the present application provide a waste heat steam generator, comprising:

[0005] a bottom plate;

[0006] a sleeve fixed on the bottom plate;

[0007] a steam generator installed in the sleeve and extending out of the sleeve at both ends, the steam generator having a flue gas inlet and a flue gas outlet at both ends;

[0008] a steam storage tank installed on the sleeve and communicating with the inside of the sleeve through a gas guide pipe;

[0009] a water inlet pipe is arranged on the sleeve, a spiral flow channel is arranged on the side wall of the inner cavity of the sleeve, the spiral flow channel communicates with the water inlet pipe, the spiral flow channel contacts the side wall of the steam generator, a plurality of heat conducting rods are installed in the spiral flow channel, and one end of the heat conducting rod is connected to the steam generator.

[0010] The external water source is introduced into the spiral flow channel through the water inlet pipe. When the inner cavity of the steam generator is processed, excessive heat is generated. At this time, the water contacts the outer wall of the steam generator, so that the water is heated. Under the action of the spiral flow channel, the flow rate of the water is slowed down, so that a large amount of heat can be absorbed. Under the action of the heat conducting rods, the heating effect of the water is improved.

[0011] Further, grooves are arranged on the heat conducting rods.

[0012] Further, the openings between the grooves on the adjacent heat conducting rods are staggered in the direction of the angle.

[0013] Further, the cross section of the groove is "V" shaped.

[0014] Further, the cross section of the groove is arc shaped.

[0015] Further, a blow-off pipe is arranged on the sleeve and communicates with the spiral flow channel.

[0016] Further, a gas outlet pipe is arranged on the steam storage tank, and a first control valve is arranged on the gas outlet pipe.

[0017] Further, a second control valve is arranged on the gas guide pipe.

[0018] Further, a pressure detection table is arranged on the steam storage tank.

[0019] Further, the smoke outlet is inversely conical.

[0020] The application has the beneficial effect of providing a waste heat steam generator with improved energy utilization rate. BRIEF DESCRIPTION OF DRAWINGS
