Description

A kind of heat energy recycling steam generator system

Technical field

The invention belongs to steam boiler technical field, specifically, is related to a kind of heat energy recycling steam generator system.

Background technology

Steam boiler can be usually used in feed production technology, in process of manufacture, steam boiler, which heats water, to be steamed To send out and form steam, the water in boiler needs to add water again after being evaporated, and after adding cold water, the air pressure and temperature of boiler internal Quickly reduce, it is necessary to be lot more time to air pressure and the temperature for reaching needs, it is impossible to keep up with manufacturing schedule.Also steam boiler After being processed to feed, flue gas is discharged by blower fan, contains substantial amounts of heat energy and dust from the high-temperature flue gas of chimney discharge, Damage of the high-temperature flue gas to blower fan is larger, and general Fans short time (typically can only continuous firing 1 month) can damage, into Originally greatly increase, and the dust in high-temperature flue gas can pollute air, be unfavorable for health.

The content of the invention

, can it is an object of the invention to provide a kind of heat energy recycling steam generator system to solve above technical problem The heat energy contained in high-temperature flue gas is reused, and will directly be supplemented by the heat energy after cool water heating to boiling point into boiler Hot water, without supplementing cold water, the efficiency that boiler produces steam greatly improves, while carries out dedusting to flue gas, more environmentally-friendly.

What the object of the invention was realized in：A kind of heat energy recycling steam generator system, its key are：Including boiler, Flue, heat-exchanging chamber and dirt pocket, the chimney of the boiler connect the smoke-intake pipe of the heat-exchanging chamber, the heat by flue The pipe of switch room connects the dirt pocket, and the heat-exchanging chamber includes the heating chamber of upper strata cold water chamber and bottom, it is described enter Smoke pipe connects the heating chamber after passing through the cold water chamber with pipe, the hot water outlet of the cold water chamber connects the boiler.

Using said structure, high-temperature flue gas is passed through the cold water of heat-exchanging chamber, wherein cold water chamber by flue caused by boiler Directly contacted with the outer wall of smoke-intake pipe and pipe, heat exchange occurs, and there is also high-temperature flue gas in heating chamber, can be to cold water chamber Surrounding and bottom carry out heat exchange heating, heat exchange area greatly increases, and heating chamber has certain memory space, has one The effect of fixed sedimentation dedusting, moreover it is possible to prevent the cold water in follow-up equipment from pouring in down a chimney into boiler；High-temperature flue gas cools through heat-exchanging chamber After lead to dirt pocket, carry out sedimentation dedusting, remove the dust in flue gas.

Further, above-mentioned dirt pocket includes water expansion chamber and gravity settling chamber, and the pipe connects the water sedimentation Room, the water expansion chamber are communicated with the top of gravity settling chamber by the tracheae that overflows, and the top of the gravity settling chamber is provided with smoke evacuation Pipe.

Using said structure, flue gas first passes through water expansion chamber and carries out dedusting, then carries out gravitational settling by gravity settling chamber, Dual dedusting, improves efficiency of dust collection.

Preferably, the pipe of above-mentioned heat-exchanging chamber connects air-introduced machine, and institute is connected in the gas outlet of the air-introduced machine by pipeline State water expansion chamber.

Using said structure, air-introduced machine is connected with pipe, and flue-gas temperature now is relatively low, the damage drop to air-introduced machine It is low, and air-introduced machine can also further prevent the water in water expansion chamber from pouring in down a chimney.

Preferably, above-mentioned heating chamber and the side wall of gravity settling chamber are equipped with dust removal door.

Using said structure, the dust deposited in heating chamber and gravity settling chamber can be purged by dust removal door.

Preferably, the bottom of above-mentioned water expansion chamber is provided with discharge pipeline.

Using said structure, the sludge in water expansion chamber can be discharged by discharge pipeline.

Further, the cold water inlet on above-mentioned cold water chamber top is provided with ball-cock assembly.

Using said structure, by ball-cock assembly sensing plus water, without artificial supervision, labor intensity is reduced.

Further, above-mentioned air-introduced machine, which is connected, water cooling tube, and the delivery port of the water cooling tube is passed through in the cold water chamber.

Using said structure, water cooling tube further can cool to air-introduced machine, prevent the high temperature and flue gas of long-term operation Temperature damage air-introduced machine.

Beneficial effect：

The present invention is a kind of heat energy recycling steam generator system, can reuse the heat energy contained in high-temperature flue gas, And hot water will directly be supplemented into boiler after cool water heating to boiling point by the heat energy, without supplementing cold water, boiler produces steam Efficiency greatly improve, while to flue gas carry out dedusting, it is more environmentally-friendly；Device damage rate is reduced, cost reduces.
