Abstract
The utility model relates to a water-bath type carburetor provided with a gas-liquid mixer, which is mainly applied in petrochemical, natural gas and air separation fields, can be used for the vaporization of liquid state natural gas, liquid oxygen, liquid nitrogen, etc., and also can be used as a peak shaving carburetor for liquid state natural gas vaporization, and can be applied in various grades of natural gas receiving stations, accumulating stations or peak shaving stations in a harbor, a city, etc. A cavity is formed in a housing; a vaporizing tube beam is arranged in the cavity, a circulation pipeline is communicated with the cavity, and a vaporization inlet tube and a vaporization outlet tube are respectively communicated with the vaporizing tube beam. The water-bath type carburetor provided with gas-liquid mixer is characterized by also including a gas-liquid mixer, and the gas-liquid mixer is respectively communicated with the vaporization inlet tube, the cavity and the circulation pipeline. According to the utility model, the structure is reasonably designed, and water attack phenomenon is hard to happen.
Description
Technical field
The utility model relates to a kind of water-bath type vaporizer that is provided with steam heater; Be mainly used in petrochemical industry, rock gas, the empty branch field; Liquified natural gas, liquid oxygen or liquid nitrogen etc. are used to vaporize; The peak regulation that also can be used as the liquified natural gas vaporization is used vaporizer, is applied to rock gas at different levels receiving station such as harbour, city, storage and transport station or peak regulation station.
Background technique
The peak regulation of liquified natural gas, liquid oxygen or liquid nitrogen of being used at present to vaporize uses that vaporizer is many to be steam-heated water-bath type vaporizer.In the common water-bath type vaporizer, the assembly that steam enters hot water adopts exhaust steam pipe 1', and exhaust steam pipe is opened the exhaust hole 2' of some, sees Fig. 1 for details.Its shortcoming is: vaporization output is offrating significantly, and when being reduced to certain value, water hammer appears in equipment.
The water hammer and the origin cause of formation thereof are: steam flow constantly reduces along with the minimizing of vaporization output; And the exhaust hole 2' perforated area on the exhaust steam pipe 1' is necessarily constant.In exhaust hole 2' cross section, the steam pressure head constantly reduces along with the minimizing of steam flow, and when steam pressure head during less than the hot water pressure head, water gets in the exhaust steam pipe 1'.Out exhaust steam pipe 1' when advancing during water, the steam flow fluctuation, vaporization output fluctuates thereupon; Water column fluctuation ground in exhaust steam pipe 1' impacts exhaust steam pipe 1', causes equipment and pipe vibration, sends noise.
The model utility content
The purpose of the utility model is to overcome the above-mentioned deficiency that exists in the existing technology, and a kind of reasonable in design is provided, and is not prone to the water-bath type vaporizer that is provided with steam heater of water hammer.
The utility model addresses the above problem the technological scheme that is adopted: a kind of water-bath type vaporizer that is provided with steam heater comprises housing, vaporization tube bank, circulation loop, steam inlet pipe, vaporization inlet tube, vaporization outlet pipe; Enclosure interior forms cavity, and the vaporization tube bank is installed in the cavity; Circulation loop communicates with cavity; Vaporization inlet tube and vaporization outlet pipe communicate with the vaporization tube bank respectively; It is characterized in that: also comprise steam heater, steam heater communicates with steam inlet pipe, cavity, circulation loop respectively.
The described steam heater of the utility model is fixed on the middle and lower part of housing.
The described steam heater of the utility model is arranged on the outside of housing.
The described steam heater of the utility model adopts tower steam heater of filler or board-like tower steam heater.
The described steam heater of the utility model adopts the tower steam heater of filler.
The utility model compared with prior art; Have the following advantages and effect: the utility model adopts the hot water of steam heater mixed steam-water generates higher temperature; The steam that substitutes existing technology directly enters the technology of heat hot water in the hot water through exhaust steam pipe; Eliminated water hammer and formation condition thereof, vaporizer work elasticity (output of promptly vaporizing scope) heightens.
Description of drawings
Fig. 1 is the prior art constructions schematic representation.
Fig. 2 is the utility model embodiment's a structural representation, and steam heater is built-in among the figure.
Fig. 3 is the utility model embodiment's a structural representation also, and steam heater is external among the figure.
Embodiment
Below in conjunction with accompanying drawing and through embodiment the utility model is done further to specify.
Embodiment:
Referring to Fig. 2 and Fig. 3, the utility model embodiment comprises housing 1, vaporization tube bank 2, circulation loop 3, steam inlet pipe 4, steam heater 6, vaporization inlet tube 7, vaporization outlet pipe 8.
In cavity 5 connections water overfall 9 is arranged.
The utility model working principle:
With the vaporization liquified natural gas is example.During work in cavity 5 splendid attire intermediary heat medium water, water level is to water line W.L..
At first, get into steam heater 6, mix, produce the hot water of higher temperature in the packing layer contact from outer steam of equipment and water from circulation loop 3; Hot water is in the water outlet distribution members enters cavity 5 equably.
Secondly, the hot water of the higher temperature annular pass of in cavity 5, flowing through from lower to upper, the heat exchanging tube tube wall in being arranged in the annular pass is caught a cold with heat exchange gas in the tube side; Liquified natural gas is got into by vaporization inlet tube 7, walks vaporization tube bank 2 tube sides, and rock gas stream from lower to upper in heat exchanging tube is heated, vaporizes through heat exchange tube wall and water heat exchange, goes out from vaporization outlet pipe 8, and its outlet temperature is greater than 0 ℃.
Once more, the hot water of catching a cold drives down through circulating line 31 water conservancy diversion and recycle pump 32, after steam heater 6 and vapor mixing; Flow into once more in the cavity 5; Impel hot water between heat exchanging tube, to flow from lower to upper, stop water, strengthen heat exchange efficiency in the frosting of catching a cold of heat exchanging tube appearance.
In addition, vapor condensation Cheng Shui increases the hot water of cavity 5, and when water level is higher than water overfall 9, hot water overflows, and makes water level keep stable.
