Abstract
The invention relates to a marsh gas desulfuration method, with H2S and other poisonous gas reacting with or absorbed by the drying agent, to generate ferric sulfide and calcium sulfide, steam adhesive to the inside of the drying agent, with condensed steam flowing out from the U shape water exhaust pipe. It is simple, low in production cost and significant in desulfuration and drying. It also applies to the desulfuration and drying for marsh gas, natural gas and coal gas.
Description
Technical field:
The present invention relates to biogas, be specifically related to a kind of method of desulfurizing and drying marsh gas.
Background technology:
The main component of biogas has methane, carbon dioxide and hydrogen sulfide, also has a spot of ammonia, nitrogen, hydrogen and carbon monoxide etc.
Hydrogen sulfide in the biogas has the stench egg flavor, is strong neurotoxic substance, enters in the blood through respiratory system, can cause the whole body toxic reaction when having little time oxidation, along with the increase of concentration of hydrogen sulfide can cause respiratory paralysis, death by suffocation.The sulfur dioxide that sulfureted hydrogen burning generates is the very strong gas of a kind of corrosivity, enter atmosphere simultaneously and can produce " acid rain ", not only can be detrimental to health contaminated environment, and meeting accelerated corrosion stove and accessory, cooker, water heater and household electrical appliance, shorten its service life.
Often contain a certain amount of steam in the biogas, can stop up gas pipeline behind these water vapor condensations, in appendix, have condensed water to stop up, often flash when biogas stove and biogas lamp burning, cause flame suddenly big or suddenly small, light is flickering, influences the result of use of biogas.The area of weather cold, in every winter, the ponding in the appendix often stops up appendix because of freezing, and biogas can not be unimpeded.
For guaranteeing health, biogas stove, biogas lamp operate as normal and protection atmospheric environment, improve the especially burning quality of biogas water heater of combustion gas tool the service life of prolongation gas-fired equipment etc., biogas must carry out the dry processing of desulfurization dewatering.The method that is used for biogas desulfurization at present is few, and it is less particularly to have the method that can carry out the dry processing of desulfurization dewatering.
Chinese patent publication number CN1629282, open day is on June 22nd, 2005, name is called " civil methane purifies and stable-pressure device ", disclose that " a kind of civil methane purification and stable-pressure device relate to a kind of purification treatment technology of civil methane.It comprises gas control valve, moisture trap, devulcanizer, voltage-stablizer and pressure gauge, and they are contained in the mounting box, connects through connecting tracheae mutually.Devulcanizer adopts U-shaped communicating pipe, and two riser upper portions have upper orifice, and the bottom mouth of pipe is arranged at the bottom, all has lid to revolve envelope respectively, and two riser upper portions respectively have the ventilation tube connector.Draining control valve is equipped with in the moisture trap bottom.Voltage-stablizer adopts spring, diaphragm, the adjustment of screw rod link gear to set more excellent pressure, guarantees that the output biogas pressure is stable, is not imported the biogas pressure fluctuation and changes.This device integrates biogas dehydration, desulfurization and voltage stabilizing, has that compact conformation, volume are little, dehydration, desulfurization, voltage regulation result be good, and the pressure clear display uses convenient, safe and reliable especially, energy savings.”
The weak point of above-mentioned patent is a complex structure, uses inconvenience, is unfavorable for applying.
Summary of the invention:
The objective of the invention is to overcome weak point in the prior art, provide that a kind of method is simple, with low cost, the method for desulfurizing and drying obvious results desulfurizing and drying marsh gas.
The method of desulfurizing and drying marsh gas is: when hydrogen sulfide in the biogas and the concave-convex bar methane desulfurizing dessicant of other pernicious gas in concave-convex rod marsh gas desulfurization and drying apparatus pass through, produce chemical reaction and physisorption, hydrogen sulfide in the biogas generates iron sulfide and calcium sulfide, steam is attracted to concave-convex bar methane desulfurizing dessicant inside, water vapor condensation Cheng Shuihou, eject from the U-shaped drainpipe, reach the purpose of desulfurizing and drying marsh gas.
Concave-convex rod marsh gas desulfurization and drying apparatus is made up of desulfurizing and drying post, concave-convex bar methane desulfurizing dessicant, last air storage chamber, escape pipe, following air storage chamber, air inlet pipe, condensation hydroecium, U-shaped drainpipe and blow-off pipe.
The preparation method of concave-convex bar methane desulfurizing dessicant is: oxidation processes, batching are pulverized, are soaked extruding, airing abrasive dust, granulation airing, roasting screening, are packaged as finished product.The batching of concave-convex bar methane desulfurizing dessicant is made up of Concave-convex clay rod, waste iron filing and dolomite.
The preparation method of concave-convex bar methane desulfurizing dessicant and concave-convex rod marsh gas desulfurization and drying apparatus separate case application patent of invention.
The present invention is achieved by following technical proposals:
The method of desulfurizing and drying marsh gas is: concave-convex bar methane desulfurizing dessicant is placed in the desulfurizing and drying post, need the biogas of desulfurizing and drying to enter down air storage chamber from air inlet pipe, hydrogen sulfide in the biogas and other pernicious gas are when concave-convex bar methane desulfurizing dessicant passes through, produce chemical reaction and physisorption, hydrogen sulfide in the biogas generates iron sulfide and calcium sulfide, be adsorbed on the concave-convex bar methane desulfurizing dessicant surface, pure biogas enters air storage chamber, lead to the kitchen range burning from escape pipe, steam is attracted to concave-convex bar methane desulfurizing dessicant inside, water vapor condensation Cheng Shuihou, fall in the condensation hydroecium, when condensed water is higher than on the condensed water plane, condensed water can eject from the U-shaped drainpipe automatically, when the sewage of cleaning condensation hydroecium and mud, sewage and mud discharge from blow-off pipe, and suspension ring are used to hang protruding rod marsh gas desulfurization and drying apparatus.
Concave-convex bar methane desulfurizing dessicant in concave-convex rod marsh gas desulfurization and drying apparatus contacts for a long time with biogas, the micropore major part of its granule interior is lost activity by hydrogen sulfide and moisture content stop up, concave-convex bar methane desulfurizing dessicant is pitchy, the concave-convex bar methane desulfurizing dessicant that can regenerate and handle or more renew.
The method that concave-convex bar methane desulfurizing dessicant regeneration is handled is: concave-convex bar methane desulfurizing dessicant is taken out in desulfurizer, be placed on earlier and carry out oxidation in the atmosphere, use clear water that concave-convex bar methane desulfurizing dessicant is washed and dries then, when concave-convex bar methane desulfurizing dessicant transfers peony to by pitchy, can be reapposed over and continue in the desulfurizer to use, finish the regeneration technology process, can repeatedly recycle through the concave-convex bar methane desulfurizing dessicant after the regeneration.
The method of concave-convex bar methane desulfurizing drying has that method is simple, low production cost and desulfurizing and drying obvious results characteristics.
The method of concave-convex bar methane desulfurizing drying is applicable to the desulfurizing dry process of biogas, natural gas and coal gas.
