Abstract
The utility model discloses a device for separating out byproduct tar residue of natural gas prepared from coal. The device comprises a cyclone separator and a spiral tubular heat exchanger, wherein the inlet and the outlet of the cyclone separator are respectively connected with a coal gasifier and the spiral tubular heat exchanger; the inlet and the outlet of the spiral tubular heat exchanger is respectively connected with the cyclone separator and a methanation reactor. Raw gas generated through gasification reaction in the coal gasifier enters the cyclone separator to be dedusted, the dedusted raw gas is discharged from the cyclone separator and then enters the spiral tubular heat exchanger, and coal tar is condensed in the spiral tubular heat exchanger and discharged from the bottom of the spiral tubular heat exchanger in a condensed liquid form. According to the utility model, through the cyclone separator and the spiral tubular heat exchanger, the effective separation of the gas, ash and the tar is achieved, the generation of phenolic wastewater is avoided, production cost is low, and the purified gas is subjected to methanation reaction to obtain high-quality natural gas. The device disclosed by the utility model is environment-friendly.
Description
Technical field
The utility model relates to the tripping device of coal preparing natural gas by product coke tar refuse, specifically a kind ofly can make effectively separated device of the tar, gaseous product and the ash content that produce in coal preparing natural gas process.
Background technology
Gas purification is a very important operation in coal process for producing natural, industrial circulating water wash method or the static trap for oil of generally adopting purifies coal gas at present, these class methods are when obtaining coal gas, the coke tar refuse that also can by-product contains in a large number solid dust and coal tar, tar later separation cost in coke tar refuse is high, purification difficult, economic benefit is bad; In addition, circulating water wash method also can produce a large amount of phenolic wastewater, causes the secondary pollution of environment, and the phenolic compound in waste water is difficult to again recycle.
Summary of the invention
The technical problems to be solved in the utility model is the problem existing for existing gas purification operation, and a kind of device of separated coal preparing natural gas by product coke tar refuse is provided, and this device can carry out coal gas, coal tar and ash content effective separated.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A device for separated coal preparing natural gas by product coke tar refuse, comprises cyclonic separator and spiral tube heat exchanger,
---the entrance and exit of cyclonic separator connects respectively coal gasifier and spiral tube heat exchanger;
---the entrance and exit of spiral tube heat exchanger connects respectively cyclonic separator and methanator.
The raw gas producing after gasification reaction in coal gasifier enters cyclonic separator ash disposal, raw gas after ash disposal enters spiral tube heat exchanger from cyclonic separator discharging, in spiral tube heat exchanger, coal tar condensation the bottom discharge from interchanger with the form of phlegma.
As a kind of preferred scheme, the upper side inlet porting of cyclonic separator, top arrange outlet, bottom has discharge port.
As the preferred scheme of another kind, in spiral tube heat exchanger, establish spiral tube, the lower side inlet porting of spiral tube heat exchanger, top arrange outlet, bottom has discharge port.
The utility model has been realized the effective separated of coal gas, ash content and tar with spiral tube heat exchanger by cyclonic separator, avoided the generation of phenolic wastewater, environmentally friendly, production cost is lower, and the coal gas after purification obtains high-quality Sweet natural gas by methanation reaction.

---the entrance and exit of spiral tube heat exchanger 2 connects respectively cyclonic separator 1 and methanator 4.Spiral tube heat exchanger 2 is for separating of the coal tar in raw gas.
The upper side inlet porting of cyclonic separator 1, top arrange outlet, bottom has discharge port.
In spiral tube heat exchanger 2, establish spiral tube, the lower side inlet porting of spiral tube heat exchanger 2, top arrange outlet, bottom has discharge port.Spiral tube bottom is provided with cold medium inlet, and top is provided with cold media outlet.
Feed coal and vaporized chemical add the charging of the gentle agent intake ducting of coal bunker from coal gasifier 3 respectively, the coal gas that coal gasification reaction produces enters cyclonic separator 1 from the discharge hole for discharge of coal gasifier 3 side tops, ash content in coal gas is from the bottom discharge mouth discharging of cyclonic separator 1, raw gas is from top exit discharging and enter spiral tube heat exchanger 2, cold medium is from the spiral tube below charging of spiral tube heat exchanger 2, from spiral tube top discharging, after heat exchange, the condensation from the bottom discharge mouth discharging of spiral tube heat exchanger 2 on spiral tube outer tube wall of coal tar in raw gas, coal gas after purification enters methanator 4 to carry out methanation reaction and obtains the synthetic natural gas that quality is higher.
The claimed scope of the utility model is not limited to above embodiment; to those skilled in the art; the utility model can have various deformation and change, all any modifications of doing within design of the present utility model and principle, improves and is equal within replacement all should be included in protection domain of the present utility model.
