Abstract

The utility model discloses a gas seal switch of biomass gas. The gas seal switch is provided with an inner core pipe (1) and a casing pipe (2), wherein a gas seal chamber (3) is arranged on the inner core pipe (1); an exhaust connecting pipe (4) and a sealing bulge are arranged in the gas seal chamber (3); one end of the casing pipe (2) is communicated with a gas outlet pipe (12) of a gasifier (13); a gas outlet (8), a wind inlet pipe (9) and a flue outlet are formed on the casing pipe (2); the inner core pipe (1) is sleeved in the casing pipe (2); and the diameter of a sealing wall (6) of the gas seal chamber (3) is the same as the inner diameter of the casing pipe (2). The friction face of the gas seal switch is very small, does not have tar and smoke dust all the time and does not cause normal rotation after being used for a long time, so the switch is used for a long time. The inner core pipe of the switch is moveably arranged in the casing pipe, so the tar and the smoke dust in a seal chamber are very convenient to clear after the inner core pipe is taken out.

Description

A kind of biological fuel gas sealing gland switch

Technical field

The utility model relates to biomass gasification device, specifically, provides a kind of burnt gas switch of biomass gasifying furnace tool.

Background technique

Biological fuel gas be utilize plant fuel by producer under airtight relative anoxia condition, adopt a kind of inflammable gas that produces after dry distillation pyrolysis and the thermochemistry oxidizing process.In family expenses biological fuel gas gasification oven, need as required after the combustion gas output to control with burnt gas switch, at present, adopt air valve or running water valve usually, no matter be metallic material or plastic material, use after several days, moving valve will become dead valve.Its reason is to contain biomass coke tar and pyroligneous acid water vapour in the biological fuel gas, very easily isolates tar and ligno acetic acid (tar is brown) when the combustion gas output intensity reduces.The sticking scheduling of tar is very high, and when combustion gas process switch, the rubbing surface in the switch will be stained with tar and flue dust.As long as this switch is stopped using, tar will be done and consolidate, and the tar of doing after consolidating has stronger sticking supernatural power, extremely scraps and switch is become.

Summary of the invention

The purpose of this utility model is to provide a kind of biological fuel gas sealing gland switch, and it can make the rubbing surface of burnt gas switch not have tar and flue dust, guarantees that switch uses for a long time.

For achieving the above object, embodiment of the present utility model is: a kind of biological fuel gas sealing gland switch, it is characterized in that, have inner core tube and sleeve pipe, inner core tube is interior blank pipe, inner core tube is provided with the sealing gland chamber, the indoor inner core tube of sealing gland is provided with outgoing gas connection tube and two seal convexities, the height of projection of outgoing gas connection tube and seal convexity is identical with the height of projection of two sealed walls of sealing gland chamber, one end of sleeve pipe and the combustion gas of gasification oven go out to manage UNICOM, sleeve pipe is provided with combustion gas discharge port, intake opening and flue portal, the one end sealing of inner core tube, and be provided with rotatable handle, the other end of inner core tube is sleeved in the sleeve pipe, combustion gas discharge port on outgoing gas connection tube on the inner core tube and two seal convexities and the sleeve pipe and flue portal and are on the same disc, and the radius of the sealed wall of sealing gland chamber is identical with the internal diameter of sleeve pipe.

Described sealing gland chamber is the groove on the inner core, and the external diameter of inner core tube is identical with the internal diameter of sleeve pipe.

The sealed wall of described sealing gland chamber is the seal ring of projection on the inner core tube, and the external diameter of seal ring is identical with the internal diameter of sleeve pipe.

On inner core tube, be provided with the limiting block handle.

The utility model is provided with the sealing gland chamber of a concave surface, and gas outlet and gas sealing port are designed to projection, the rubbing surface of burnt gas switch is very little, rubbing surface does not have tar and flue dust forever, and because air intake pipe communicates with the sealing gland chamber all the time, and meeting is in the indoor generation vapour lock of sealing gland, sealing gland is indoor can not to enter tar and flue dust, therefore can not cause the normal rotation of burnt gas switch, guarantee that switch uses for a long time.And the inner core tube of switch is movably arranged in the sleeve pipe, can easily remove after the taking-up.
