Abstract
A boiler dead steam recovery unit comprises a barrel body, a sprayer, a sieve plate, a dead steam inlet pipe and a condensation water outlet pipe, wherein the sprayer is arranged at the upper part in the barrel body, the sieve plate is arranged below the sprayer, the dead steam inlet pipe is connected on the wall of the barrel body below the sieve plate, and the condensation water outlet pipe is connected with the bottom of the barrel body. For the boiler dead steam recovery unit, softened water is uniformly sprayed on the sieve plate by the sprayer, dead steam enters the barrel body by the dead steam inlet pipe and can form a very thin water film with the softened water on the surface of the sprayer for carrying out heat exchanging, so that the dead steam is changed to condensation water. The condensation water flows into a softened water tank by the condensation water outlet pipe, so that the water temperature in the tank is raised, therefore, the low-pressure dead steam can be ensured to flow into a recovery unit constantly and boiler fuel can be saved by 6% to 8%. The recycling rate of water can reach above 90%, so that a water resource can be saved efficiently. Due to the separation state between the condensation water and air, the excellent quality of boiler feedwater of a part can be kept, and the treatment cost on softening and deoxidization of the boiler feedwater is reduced. In order to preventing corrosive gas from entering a boiler again, the coal consumption of the boiler can be reduced relatively, thereby achieving the aims of China, such as energy conservation, emission reduction and recycling economy.
Description
Technical field
The utility model relates to the device that the very big enterprise's recovery valve vapour of industry technology gas consumption such as electric power, oil, chemical industry, weaving, papermaking, food are used.
Background technology
Because rising steadily of international energy price, domestic coal price is also unprecedented soaring, and energy savings, reduction entreprise cost become each enterprise's urgent task.And Industrial Boiler is in operation and is equipped with oxygen-eliminating device and boiler platoon, arranges flash vessel surely and produce a large amount of exhaust steam and outwards discharge, and causes great energy loss and waste.
The utility model content
The purpose of this utility model provides a kind of boiler steam exhaust recovering device, to solve the energy waste problem.
For achieving the above object, the utility model provides a kind of boiler steam exhaust recovering device, it is characterized in that: comprise cylindrical shell, spray equipment, sieve plate, exhaust steam inlet tube, condensate water outlet, the cylindrical shell internal upper part is provided with spray equipment, sieve plate is set below the spray equipment, connect weary gas inlet tube on the sieve plate lower barrel wall, the cylindrical shell bottom connects the condensate water outlet.
Spray equipment is to be connected in sequence by demineralized water inlet tube, water knockout drum, spiral nozzle.
The utility model utilizes demineralized water evenly to be sprayed on the sieve plate by spray equipment, and exhaust steam enters by the exhaust steam inlet tube and forms very thin water membrane with demineralized water on the sprayer unit surface in the cylindrical shell and carry out heat exchange, and exhaust steam becomes condensate water.Condensate water flows into softening water tank by the condensate water outlet, improves water temperature in the softening water tank, guarantees that thus the low pressure exhaust steam constantly flows into retracting device, saves boiler oil 6%～8%; Secondly, the cyclic utilization rate of water has been saved water resource effectively up to more than 90%; The isolation of condensate water and air makes this part boiler feedwater can keep good quality simultaneously, has correspondingly reduced the disposal cost that reaches deoxygenation is softened in boiler feedwater; In addition, avoided corrosive gas to dissolve in boiler again, from then on reduce boiler consumption coal relatively, thereby it has been energy-saving and cost-reducing to reach China, the purpose of recycling economy.

Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the spray equipment structural representation.
The specific embodiment
With reference to Fig. 1, the utility model comprises cylindrical carbon steel cylinder 1, spray equipment 2, exhaust steam inlet tube 3, sieve plate 4, condensate water discharge 5, demineralized water evenly is sprayed on the sieve plate by the demineralized water spray equipment, sieve plate is with making with laser drill on the stainless-steel sheet, exhaust steam enters by the exhaust steam inlet tube and forms very thin water membrane with demineralized water on the sieve plate surface in the cylindrical carbon steel cylinder and carry out heat exchange, exhaust steam becomes condensate water, condensate water flows into softening water tank by condensate water discharge, guarantees that thus the low pressure exhaust steam constantly flows into retracting device.
With reference to Fig. 2, spray equipment is to be connected in sequence by demineralized water inlet tube 6, water knockout drum 7, spiral nozzle 8.
