Description
Technical field
The utility model relates to a kind of vaporization constant pressure air feeding integrated device, particularly the on-the-spot air feeder of a kind of skid-mounted ultra-pure ammonia.
Background technique
In recent years, under the background of global concern low-carbon economy pattern, clean energy resource and power-saving technology are greatly developed in countries in the world, pay close attention to low-carbon economy.Under this background, LED technology and the related industry of China have obtained fast development.Especially the semiconductor lighting technology take the high brightness GaN-based blue-ray LED as core has been brought very large impact to lighting field, and becomes the focus of present global semiconductor area research and investment.Along with the fast development of the photoelectronic industries such as light emitting semiconductor device (LED), the monolithic design production capacity in industry has had the growth of explosion type, and the demand of upstream materials has been had more huge demand.
The 7N electronic grade ultrapure ammonia is a kind of important raw and processed materials in the LED industry, is the important foundation material that the MOCVD technology prepares GaN.Its basic principle is that ultra-pure ammonia is used for metallo-organic compound chemical vapor deposition (MOCVD) epitaxial process, and it issues biochemical reaction generation gallium nitride with the predecessor trimethyl gallium (Ga (CH3)) of metallorganic in High Temperature High Pressure:
Ga(CH3)3(g)+NH3(g)→GaN(s)+3CH4(g)。
Gallium nitride is the core of LED technology, is determining the development of LED industry.Therefore, the development of industry is had higher requirement to the supply of ultra-pure ammonia.At present, the consumption scale of the monomer factory in global LED industry to ultra-pure ammonia, the maximum flow of its supply is no more than 100Nm3/h, and in actual demand, and its quantity of LED factory that the flow of ultra-pure ammonia is surpassed 400Nm3/h increases sharply.
[0004] in current LED production process, the scene of widely used three kinds of ammonia tanks to ultra-pure ammonia (Y bottle, T bottle, ISO tank car) vaporization blowing model is as follows:
| The canned mode of liquefied ammonia | The vaporization mode | Air demand | Voltage regulating mode |
| The T bottle | Electric blanket covers the bottle heating | ≤ 12 Nm3/h | The manual pressure regulating valve combination |
| The Y bottle | Electric blanket covers the bottle heating | ≤ 30 Nm3/h | The manual pressure regulating valve combination |
| The ISO tank car | At the bottom of electric heating chuck heating tank | ≤ 96 Nm3/h | The manual pressure regulating valve combination |
Though above-mentioned several plenum system is adopted in a large number, have larger narrow limitation: all adopt Electric heating to realize the vaporization of liquefied ammonia, power consumption is larger; It is larger that the air supply system internal pressure is subjected to heating source temperature, flow etc. to affect fluctuation, makes the interior gas of supply air line that the possibility of potential liquefaction be arranged.The utility model patent (ZL 201120093007.4) of the grand gas companies of gold has been reported and has been replaced with air source heat pump hot water system that electric heating is energy-conservation to realize, not limit flow and the large flow vaporization constant pressure air feeding system of a kind of ultra-pure ammonia that can constant voltage output.Yet the ISO of this system tank car and heating operative installations adhere to different system separately, pipeline is longer, inconvenience is installed, and need the client to provide for oneself or rent air source hot pump water heater and water bath type vaporizer, increased user cost, be subjected to the region spacial influence larger, thereby limited its further extensive use.
Summary of the invention
In order to overcome defects, the utility model provides the system of the larger gas consumption demand in a kind of LED of satisfying client use gas scene, and this system is movably, can stablize the on-the-spot air feeder of a kind of skid-mounted ultra-pure ammonia of output.
The technical solution of the utility model is: the on-the-spot air feeder of a kind of skid-mounted ultra-pure ammonia, this device comprise liquefied ammonia tank car, knock out drum, air source heat pump hot water system, constant pressure regulating valve group and automatic control system and carry car.Described liquefied ammonia tank car and knock out drum outside all are designed with chuck, and described liquefied ammonia tank car pipeline is connected with the air source heat pump hot water system water outlet; Described knock out drum is connected with the outlet of liquefied ammonia tank car, described knock out drum JI is connected by pipeline with liquefied ammonia tank car JO, described air source heat pump hot water system is connected with liquefied ammonia tank car outlet line water intake, to guarantee that hot water circulates between tank car and knock out drum; Described voltage-regulating system connects the knock out drum outlet line, and described automatic control system is regulated pressure and the flow of voltage-regulating system, by the ammonia of voltage-regulating system output constant voltage.
Described knock out drum, air source heat pump hot water system, constant pressure regulating valve group and automatic control system are carried the car carrying with one jointly.
The chuck skin of described liquefied ammonia tank car and knock out drum wraps up with thermal insulating material, and chuck inside is provided with hot water cyclesystem.
The beneficial effects of the utility model are: adopt this system, can not only realize the effect of patent ZL 201120093007.4, and the efficient docking that has realized easily ISO liquefied ammonia tank car and heating system, satisfy client's demand and need not the client and increased subsidiary equipment, overcome the restriction of time, space and region, be conducive to further opening up of corporate client source; Adopt the jacketed type hot water cyclesystem to increase the utilization ratio of hot water, reduced thermal loss; The air feed that adopts knock out drum to prevent that not only Yin Wendu, pressure or some artificial operation factors from causing unstable or due to raw materials ammonia because the not enough liquefaction of heat supply causes damage to manufacturing mechanism, more can further purify to the finished product ammonia, guarantee the quality of air feed.
