Abstract
The utility model discloses a urea high-pressure tempered water waste heat recycling device, belongs to a wastewater waste heat recycling device and aims to provide an industrial wastewater waste heat recycling device which is energy-saving and environment-friendly, has a simple structure and can be used for improving the efficiency of a boiler. The urea high-pressure tempered water waste heat recycling device comprises a water tank communicated with a urea tempered water outlet pipe by a water pump. The water tank (3) is communicated with a boiler water tank by a heat exchanger (4); and one water outlet of the heat exchanger (4) is communicated with urea production equipment by a urea tempered water return pipe (6), while the other water outlet of the heat exchanger is communicated with the boiler by a boiler water inlet pipe (5). The urea high-pressure tempered water waste heat recycling device has various advantages of simple structure, energy conservation, environmental protection, low investment cost and the like, and is the industrial wastewater waste heat recycling device suitable for chemical enterprises.
Description
Technical field
The utility model relates to a kind of waste water residual heat recycle device, relates in particular to a kind of urea high pressure temperature adjustment water heat recovery device.
Background technology:As everyone knows, in urea production process, can produce big amount temperature up to 130 ℃, pressure is the high pressure temperature adjustment water of 0.3MPa.For using water wisely, all be to utilize cooling column that high pressure temperature adjustment water is lowered the temperature at present, and then recycle; The waste heat of high pressure temperature adjustment water not only is not fully utilized, but also needs to build cooling column.In addition, need a large amount of steam in the urea production, consume a large amount of energy; If can utilize the waste heat of urea high pressure temperature adjustment water that boiler feed water is carried out preheating; Not only can improve the initial temperature of boiler feed water; Thereby improve the boiler efficiency of heating surface, reduce energy consumption, and can also lower the temperature, remove from the required investment of construction cooling column high pressure temperature adjustment water.
Summary of the invention:In order to overcome the defective that exists in the prior art, the utility model aims to provide a kind of energy-conserving and environment-protective, simple in structure, the urea high pressure temperature adjustment water heat recovery device that can improve boiler efficiency.
To achieve these goals, the utility model adopts following technical scheme: it comprises the water tank that is communicated with urea temperature adjustment outlet pipe through water pump; Water tank is communicated with boiler water tank through heat exchanger, and a delivery port of heat exchanger passes through that urea temperature adjustment return pipe is communicated with urea production equipment, another delivery port of this heat exchanger passes through boiler water inlet pipe and is communicated with boiler.
Compare with prior art; The utility model is owing to adopted technique scheme; Therefore with heat exchanger water tank and boiler water tank are coupled together, can utilize the waste heat of high pressure temperature adjustment water that boiler feed water is preheated to 95 ℃, not only improved the efficient of boiler but also reduced the energy consumption of boiler; In addition, adopt technique scheme also can practice thrift a large sum of expense of building cooling column.Plurality of advantages such as it is low to the utlity model has simple in structure, energy-conserving and environment-protective, investment and operating cost, and economic and social benefit is very remarkable.
Description of drawings:
Fig. 1 is the structural representation of the utility model.
Among the figure: urea temperature adjustment outlet pipe 1 water pump 2 water tanks 3 heat exchangers 4 boiler water inlet pipes 5 urea temperature adjustment return pipes 6
The specific embodiment:Below in conjunction with accompanying drawing and concrete embodiment the utility model is described further:
As shown in Figure 1: urea temperature adjustment outlet pipe 1 is communicated with water tank 3 through water pump 2, and this water tank is communicated with the boiler water tank (not shown) through heat exchanger 4, and there are two delivery ports the below of this heat exchanger; One of them delivery port is communicated with the urea production equipment (not shown) through urea temperature adjustment return pipe 6, and another delivery port is communicated with the boiler (not shown) through boiler water inlet pipe 5.
