Abstract

The utility model discloses a steam return water waste heat recovery device and belongs to the field of energy-saving equipment. The device comprises a heat exchanger, a steam return water tank, a spray group and a spray pump. A steam return water pipe is arranged in the middle of the steam return water tank, the spray group is arranged on the upper portion, a temperature transmitter, a spray circulating pump and a water replenishment pump which are communicated with a water tank return liquid respectively are arranged on the lower portion, an exhausting pipe is arranged at the bottom, and an emptying pipe is arranged at the top. A water outlet pipe of the spray circulating pump is communicated with the heat exchanger, and a pipe led out of the heat exchanger is connected with the spray group after passing through a temperature adjusting valve. By means of the steam return water waste heat recovery device, losses of softened water caused by the fact that high-pressure circulatory return water is vaporized in quantity when reducing to the normal pressure are prevented, recovered heat energy can be used for warming in winter and preheating production and living hot water such as feeding water of boilers.

Description

Steam backwater waste-heat recovery device
Technical field:
The utility model belongs to the steam afterheat recovery device of a kind of energy saver, particularly a kind of chemical enterprise.
Background technology:
In chemical process, with the mode extensive use of water vapour heat by conduction amount.As the purification of process pipe companion heat, reactor heating and rectifying column etc.Its steam temperature of different applications and pressure are also different.The water that produces steam is the boiler soft water of processing through softening, has removed in water and has easily produced the mineral ion of incrustation scale.Steam can reduce temperature and pressure because heat is absorbed in Thermal Cycling, thereby by the steam backwater of gaseous state liquefy.The liquid that returns that the steam of different pressures produces converges in the steam recovery tank of normal pressure.Because of pressure decreased, have a large amount of high temperature liquid waters and become steam, the blow-down pipe by tank top is discharged in atmosphere, this discharge not only can be lost a large amount of heat energy, also can lose a large amount of demineralized waters, cause the waste of the energy and water resource, increase operating cost.
Summary of the invention:
The purpose of this utility model is a kind of steam backwater waste-heat recovery device of design, recycles the heat energy of steam, prevents the waste of demineralized water resource.
Adopted following technical scheme: steam backwater waste-heat recovery device comprises heat exchanger, steam recovery tank, spray group and spray pump for this reason.There is the steam return pipe at the middle part of steam recovery tank, and the spray group is arranged at top, and bottom has respectively returns with water tank temperature transmitter and Sprayer Circulation pump and the small pump that liquid is communicated with, and bottom drains pipe, and blow-down pipe is arranged at top; The outlet pipe UNICOM heat exchanger of Sprayer Circulation pump, from heat exchanger, pipeline out joins with the spray group by temperature control valve (TCV).
Described spray group is comprised of a plurality of spray heads, and each spray head stretches into water tank inside.
The use of steam backwater waste-heat recovery device has prevented from when the cycle of higher pressure backwater from dropping to normal pressure vaporizing in a large number, causes the loss of demineralized water, and the heat energy of recovery can be used for the productive life hot water such as warming, the water inlet of preboiler.
The accompanying drawing explanation:
Fig. 1 is the structural representation of steam backwater waste-heat recovery device.
The specific embodiment:
Below in conjunction with accompanying drawing, be further described.
As shown in drawings, steam backwater waste-heat recovery device, comprise heat exchanger, steam recovery tank, spray group and spray pump.There is steam return pipe 2 at the middle part of steam recovery tank 8, and the heating steam condensate return in process units enters the recovery tank of atmospheric pressure state by the steam return pipe, and because of pressure drop, the operative liquid water vapor, gather recovery tank top.The spray group 6 that recovery tank top is comprised of numerous spray heads, each spray head gos deep into water tank inside, in order to reach best spraying effect, the circular water curtain that each spray head produces with periphery spray water curtain, certain stack is arranged, to reach seamless connection.In low temperature water smoke decline process, with the steam risen, meet, after water smoke absorbs steam heat, temperature raises, and becomes high-temperature water and accumulates in the water tank bottom.The recovery tank bottom has respectively returns with water tank temperature transmitter 10 and Sprayer Circulation pump 11 and the small pump 7 that liquid is communicated with, and bottom drains pipe 9, and blow-down pipe 5 is arranged at top.High-temperature water in recovery tank pumps into heat exchanger 1 by the Sprayer Circulation pump, complete heat exchange after water temperature reduce, then enter spray group 6 by temperature control valve (TCV) 3.High-temperature water in recovery tank is squeezed into after the steam generator heating and is become steam and return in production equipment and circulate by small pump.Water temperature in recovery tank should be controlled at suitable scope, and the too high meeting of temperature causes the cavitation erosion of pump, and temperature is hanged down needs to increase extra heat production steam.The temperature signal that temperature control valve (TCV) 3 transmits according to temperature transmitter 10 carries out the regulation of valve automatically, by shower water flow size, controls water tank temperature.Also can carry out the moisturizing displacement to guarantee that water tank temperature is in normal range (NR) by the pipeline 9 of putting into of moisturizing pipeline 4 and water tank bottom in case of necessity.
