Description
Technical field
The present invention relates to the defeated coal carbon-dioxide gas compressor feeders of coal gasification, and in particular to plant area does not have high pressure nitrogen
Powdered coal pressuring gasified furnace enterprise convey gas source in fine coal conveying when start-up or carbon-dioxide gas compressor break down
Selection.
Technical background
The gas that fine coal is conveyed in powdered coal pressuring gasified technique generally uses nitrogen or carbon dioxide gas, and nitrogen comes from space division
Process, carbon dioxide gas come from cleaning procedure.For the device that product is liquefied ammonia, fine coal disclosed in CN207390485U adds
One kind is provided in pressure gasification conveying device when carbon dioxide does not have Supplying gas condition, using the high pressure nitrogen that space division is ready-made
It is supplied directly to coal handling system, so that defeated coal carbon-dioxide gas compressor be avoided to generate when low-pressure nitrogen and carbon dioxide switch
Gasify fluctuation of service problem caused by gas flow and pressure oscillation.At the same time it can also event occur in carbon-dioxide gas compressor
When barrier, avoid due to gasification furnace stop and cause full factory stop the drawbacks of.But for the dress with ethylene glycol, methanol etc. for product
It sets, does not meet the nitrogen gas source of pressure condition and tolerance condition, if in early period of driving without carbon dioxide or pressurized carbon dioxide
Contracting machine will be unable to guarantee gasification process smoothly defeated coal when breaking down, serious to cause system shutdown.
Summary of the invention
The present invention provides a kind of defeated coal carbon dioxide feeder of coal gasification, to solve product as ethylene glycol, methanol etc.
Because of the problem of defeated coal gas source is insufficient or defeated coal carbon-dioxide gas compressor failure influences defeated coal in fine coal pressing technology device.
Purpose to realize the present invention, this defeated coal carbon dioxide feeder of coal gasification, it includes and pressurized carbon dioxide
The connected surge tank of contracting machine, it is characterised in that the carbon-dioxide gas compressor outlet is divided into two-way, wherein connecing carbon dioxide all the way
Surge tank, another way enter liquid carbon dioxide storage tank after co 2 liquefaction device, and liquid carbon dioxide storage tank exports successively
Carbon dioxide buffer tank, the carbon dioxide buffer tank outlet and the defeated coal measures of fine coal are followed by through delivery pump and carbon dioxide gasification device
System connects, and is installed with pressure alarm controller on the carbon dioxide buffer tank, the pressure alarm controller through motor with it is defeated
Pump is sent to be electrically connected.
The co 2 liquefaction device outlet converges with liquid carbon dioxide is followed by liquid carbon dioxide storage tank, liquid two
Carbonoxide outlet is successively followed by carbon dioxide buffer tank through delivery pump and carbon dioxide gasification device, and carbon dioxide buffer tank goes out
Mouth connects with fine coal coal handling system, and pressure alarm controller, the pressure alarm control are installed on the carbon dioxide buffer tank
Device processed is electrically connected through motor with delivery pump.
The technological progress achieved by the present invention: 1. with coal gasification gas, product is the pressing technology dress of ethylene glycol, methanol
It sets, can be used when normal operation that the present invention is spare by co 2 liquefaction storage more than needed, the titanium dioxide of gasification storage when driving
Carbon is conveyed for fine coal, is avoided the preceding pressurized nitrogen of carbon-dioxide gas compressor driving, is needed to refund compression two after normal production
The troublesome operation of carbonoxide saves the time of driving.
2. if gasification workshop section's fine coal can be used pre-stored two when carbon-dioxide gas compressor failure or tolerance deficiency
Carbonoxide conveying, avoid as carbon dioxide supply interrupt and caused by gasification furnace stop, or even the hair of full factory parking accident
It is raw, reduce economic loss caused by parking accident.

Specific embodiment
Embodiment 1: the defeated coal carbon dioxide feeder of coal gasification of the present invention is as shown in Figure 1, it includes and two
The connected surge tank 7 of carbonoxide compressor 1,31 DEG C from purification section, the carbon dioxide of 0.16MPa enter pressurized carbon dioxide
Contracting machine 1 pressurizes, and the high-pressure carbon dioxide come out from carbon-dioxide gas compressor 1 is directly accessed carbon dioxide buffer tank 7 all the way；It is another
Road enters co 2 liquefaction device 3 after valve 2, and the outlet of co 2 liquefaction device 3 connects liquid carbon dioxide storage tank 4, controls
The temperature of liquid carbon dioxide storage tank 4 processed is 25 DEG C, and pressure is not less than 6.43MPa, the liquid that liquid carbon dioxide storage tank 4 exports
Carbon dioxide squeezes into carbon dioxide gasification device 6 after delivery pump 5 and gasifies, out the gaseous state titanium dioxide of carbon dioxide gasification device 6
Carbon accesses fine coal coal handling system after carbon dioxide buffer tank 7, and pressure alarm controller is installed on carbon dioxide buffer tank 7
8, pressure alarm controller 8 connects after motor M with 5 electricity of delivery pump.
Embodiment 2: as shown in Fig. 2, the present embodiment difference from Example 1 is the outlet of co 2 liquefaction device 3
