Description
Technical field
The present invention relates to energy technology field, especially a kind of vapor compressor exhaust pipe for the pressurization that can cool down.
Background technique
Requirement of the modern industry to efficiency of energy utilization is higher and higher.And in industrial processes, the energy of evaporation technology
Amount consumption accounting is very high.Therefore, evaporation technique is improved, huge economic benefit and Ecological Effect can be brought by improving evaporation efficiency
Benefit.
In existing industrial production, by multi-effect evaporator come realize evaporation and concentration in the way of it is more universal.The technology
Although making the steam being finally discharged that there is lower pressure and temperature, the energy consumption of evaporation technology is reduced to a certain extent,
It is the latent heat of vaporization needed for most energy are all used to provide liquid evaporation in vapor evaporation process, only one small portion
The temperature and pressure for dividing energy to be used to improve vapor.So multi-effect evaporator can not be to the energy consumption amount of bringing of evaporation process
Variation in grade.
Mechanical vapor recompression technology is pressurizeed by the vapor to low-temp low-pressure and is done work, and can be allowed to regain heating
The ability of solution, to realize recycling for the latent heat of vaporization.Therefore, mechanical vapor recompression technology reduces the amplitude of energy consumption more
Greatly, higher to the promotion of the utilization efficiency of the energy, production cost can be greatly reduced.
In the art, the pressure of vapor compressor is relatively high, and the realization difficulty of compression process is larger.In addition, vapor
After a series of pressure processes, temperature is also correspondinglyd increase, and the higher degree of superheat is brought greatly to the utilization of vapor
It is difficult.
Summary of the invention
A kind of vapor compressor row of pressurization that can cool down is provided it is an object of the invention to solve above-mentioned technical problem
Tracheae, to solve the problems, such as that pressure ratio needed for compression process is excessively high in vapor compressor and vapor overheats after compression process
Spend higher problem.
In order to solve the above-mentioned technical problem, the present invention adopts the following technical scheme:
A kind of vapor compressor exhaust pipe for the pressurization that cools down, including straight pipe, expansion pipeline section, nozzle and sparge pipe,
The straight pipe and expansion pipeline section perforation link together, and the internal diameter of straight pipe is less than the internal diameter of expansion pipeline section, the water spray
The output end of pipe extends to the inside of straight pipe, and the nozzle is mounted on the output end of sparge pipe, nozzle direction expansion pipeline section
It is arranged so that liquid mist is injected to expansion inner tube segment.
Preferably, it is connected smoothly between the straight pipe and expansion pipeline section using variable diameter pipeline section, and three coaxially sets
It sets.
Preferably, the straight pipe, variable diameter pipeline section and expansion pipeline section are made into integration.
Preferably, the straight pipe, variable diameter pipeline section and expansion pipeline section are successively welded.
Preferably, the nozzle and expansion pipeline section coaxial arrangement, and the water jet of nozzle is in the miner diameter end of variable diameter pipeline section
At mouthful.
The beneficial effects of the present invention are:
1. the present invention is without external impetus system, structure is simple；
2. the present invention is stable in high temperature and pressure, reliability is higher；
3. mist flow of the invention is controllable, good cooling effect, good for the vapor adaptability of different conditions.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the vapor compressor exhaust pipe of the pressurization of the invention that can cool down.
Specific embodiment
The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments:
Referring to Fig. 1, the vapor compressor exhaust pipe of the pressurization that cools down of the invention include straight pipe 1, variable diameter pipeline section 5,
Expand pipeline section 2, nozzle 3 and sparge pipe 4.
The straight pipe 1, variable diameter pipeline section 5 and expansion pipeline section 2 coaxially perforation link together, three can be made into integration or
It is successively to be welded.Wherein the internal diameter of straight pipe 1 is less than the internal diameter of expansion pipeline section 2.
The output end of the sparge pipe 4 extends to the inside of straight pipe 1, specifically, the aperture on the outer wall of straight pipe 1,
The output end through hole of sparge pipe 4 is inserted into inside straight pipe 1 again, seals and is welded and fixed later.
The nozzle 3 is mounted on the output end of sparge pipe 4, and is equipped with elbow between the two to guarantee that nozzle 3 and expansion are managed
Section 2 can be coaxially disposed, and the water jet of the nozzle 3 towards the setting of expansion pipeline section 2 and nozzle 3 is in the miner diameter end of variable diameter pipeline section 5
At mouthful, such structure design is expanded inside pipeline section 2 convenient for liquid mist can be equably injected to.
After the high-temperature high-pressure steam of vapor compressor discharge is via 1 transition of straight pipe, into expansion pipeline section 2 and at it
The mixed process of middle completion and liquid mist.Under the collective effect of expansion pipeline section 2 and the liquid mist sprayed, cooling pressurization is completed,
And it is passed through another straight pipe after expansion pipeline section, transition enters follow-up equipment.
The process of pressurization of the vapor in the vapor compressor exhaust pipe that can cool down pressurization are as follows:
When by expanding pipeline section 2, flow velocity can reduce the vapor of subsonic flow, so as to cause the reduction of kinetic energy,
And reduced kinetic energy a part converts the pressure potential for vapor, another part is converted into the interior energy of vapor, therefore,
After this exhaust pipe, the corresponding pressure of vapor rises.
The process of cooling of the vapor in the vapor compressor exhaust pipe that can cool down pressurization are as follows:
Liquid water in sparge pipe is by becoming the lesser liquid mist of partial size after nozzle, in the vapor of high temperature and pressure,
The liquid mist of this type is easily evaporated, and in the evaporation process of liquid mist, has taken away a large amount of heat in vapor, so that vapor institute
It can be reduced containing interior, therefore, after this exhaust pipe, the corresponding temperature of vapor is reduced.
In conclusion the contents of the present invention are not limited in the above embodiments, those skilled in the art can be
It is proposed other embodiments within technological guidance's thought of the invention, but these embodiments be included in the scope of the present invention it
It is interior.
