Description
Technical field
A kind of propellant deslagging processing equipment is the utility model is related to, belongs to environmental protection technical field, is specially one kind
Portable propellant slag-draining device.
Background technology
Rocket loading system is the important component of space launching site, and propellant mass is the key of loading system, its
Middle particulate matter and mechanical admixture index is particularly critical.In recent years, when space product filling checks filtering after terminating, filter is found
There is cotton-shaped crystal in screen surface, this phenomenon shows launching site storehouse basin by long-term use of, basin in various degree
There is crystal, propellant receptacle pot bottom for bottom to have residue.
Through subject study, it is believed that the formation of crystal is a complex process, and its main cause is to work as in propellant quite
Water content is exceeded, while the device material corrosion such as tank wall, channel wall, valve in the case where pressurizeing, return the effect of the external conditions such as stream
Accelerate, make salt content increase during propellant storage, crystal is separated out after reaching certain saturation degree, and then in repropellenting system
Crystal is formed in system.Through constituent analysis, it is found that crystal mainly exists with nitrate salts, original sample is by Fe (NO3)3、Cr
(NO3)3、Al(NO3)3、SiO2、ZrO2Mixing composition.
In propellant the generation of crystal by etching apparatus, block pipeline, to key equipment in ground loading system as plus
The generations such as pump, flowmeter, valve, basin, metal hose harm is noted, consumes substantial amounts of maintenance management funds；Launching site storehouse
Basin dregs drastically influence propellant mass, if being cleared up not in time, even crystal, which once breaks through screen pack, enters fire
Arrow tank, cause engine nozzle and each transfusion air delivering pipeline system jams, it will potential safety hazard is caused to space launch mission,
Possibly even cause mission failure, cause the loss that can not be estimated.
To ensure propellant mass in rocket filling process, launching site ground loading system expense is reduced, it is necessary to transmitting
The crystal of field propellant receptacle pot bottom residual is cleared up in time.
At present, launching site leads to mainly by the way of external conical filter, road tanker metaideophone mouth are connected with slag-drip opening
Cross nitrogen extruding and carry out basin cleaning, filtering, reduce the crystal in propellant as far as possible.This Slagoff method needs complicated match somebody with somebody
Complete equipment and pipeline, technological process is complicated, workload is larger and costly.
The content of the invention
The utility model aims to provide that a kind of process is simple, is easily manipulated, the portable propellant slag-draining device of totally-enclosed.
Essence of the present utility model is by propellant metaideophone is into slag-draining device in the ground loading system basin of launching site, so
Sample examination is carried out afterwards, is pressurized, goes out liquid, realizes that propellant remains the deslagging processing of liquid.
The utility model provides a kind of portable propellant slag-draining device, including motor-bug, is installed on motor-bug
There is deslagging tank, deslagging tank top is provided with manhole, and manhole is provided with pressure gauge, goes out liquid sampling line, gas exhaust piping and pressure inlet
Road, water influent pipeline and blowoff line are additionally provided with deslagging tank, magnetic double level gauge, magnetic turnover panel liquid level are also configured with deslagging tank
Meter lower section is provided with liquid level exhaust-valve, pressure gauge, goes out liquid sampling line, blast pipe, pressure piping and blowoff line and is all configured with
Valve.
Technological process of the utility model to propellant deslagging in the basin of launching site, comprises the following steps：1. the deslagging
The deslagging tank water influent pipeline of device, by connection by metal hose, is opened deslagging tank gas exhaust piping, led to launching site propellant basin
Certain nitrogen pressure in maintenance basin is crossed, propellant in basin is remained into deslagging tank by liquid metaideophone using fashion of extrusion.2. pass through
Deslagging tank goes out liquid sampling line, and propellant is sampled and chemically examined, to determine whether propellant mass is qualified.3. pass through increasing
Nitrogen pressure in deslagging tank is pressurized to 0.2MPa by pressure mouth.4. if the propellant chemical analysis sampled out is up-to-standard, pass through deslagging
Tank goes out liquid sampling line, and the propellant liquid extruding in deslagging tank is taken out to apart from deslagging pot bottom 10cm positions and stopped（Go out
Liquid sampling line length is extended at deslagging tank 10cm, while deslagging tank liquid level can be read by magnetic double level gauge）, the portion
Divide propellant to transfer back in the basin of launching site to be continuing with, residual propellant residue liquid is arranged by blowoff line in deslagging tank
Go out；If the propellant chemical analysis sampled out is off quality, propellant residue liquid in deslagging tank is directly passed through into blowoff line
Discharge, for using the less demanding other systems of propellant mass, or direct burning disposal.
After deslagging tank is discharged propellant liquid by blowoff line, deslagging tank need to be cleaned, to recover to dispatching from the factory
State.Deslagging tank cleaning procedure is：First cleaned using neutralizer, then degreasing is carried out using alcohol, then dried with hot-air
Dry deslagging top tank structure, last inspection personnel wear togs, and entering deslagging tank from manhole carries out cleanliness factor inspection, to confirm to arrange
Slag ladle state.
The beneficial effects of the utility model：
（1）Propellant in the basin of launching site is extruded into deslagging tank, then is sampled chemical examination, optionally propellant is entered
Row recovery, it is another use it for anything else or burning disposal, solve that tank volume is huge, be not easy to carry out the deficiency of propellant deslagging processing；
（2）In deslagging processing procedure, basin is closed with slag-draining device, and no waste liquid produces, no propellant gas diffusion
To surrounding enviroment, and new secondary pollution is not generated in processing procedure need to handle；
（3）Deslagging tank is positioned on motor-bug, and hanger is set in deslagging tank outer surface, thus slag-draining device being capable of spirit
Work is motor-driven, and a set of slag-draining device can be used for the deslagging processing of multiple propellant basins simultaneously, and it is irremovable to solve multiple basins
The drawbacks of.
