Abstract

The utility model provides an experimental device of a gas generator. The utility model is a sealed container which is divided into four layers, wherein the innermostlayer is provided with a pressure cooker (8) of which the interior is provided with coal blocks (9), and the periphery of the pressure cooker is coated with mica plates (1) of refractory insulating materials; the periphery of each mica plate is coated with heating wire plates (2), and the exterior of each heating wire plate is wrapped with thermal insulating cotton (3); then, the pressure cooker is arranged in an outer shell (7); two holes are arranged on a high pressure cooker lid (10); a left side hole is inserted into a temperature measuring bar (5) of which the top end is connected with a thermostat (6), and a right side hole is connected with a soft tube which is used as a carbon monoxide vent hole (4). A power supply socket (11) capable of switching on a power supply is arranged below the container. The utility model has the advantages simple structure, convenient manufacture, high heat conversion rate and strong safety; the utility model can be fabricated through using available resources of a school, and because the experiment of a teaching aid is clear, the utility model is a good teaching tool for the school.

Description

The gas producer

Technical field:

The utility model belongs to the teaching aid field.Be specifically related to a kind of experimental installation of gas producer.

Background technology:

People often can know that from report the coal seam can produce gas when mining in the tunnel, the miner is poisoned even blast accident as untimely eliminating.We know again when coal yard is stacked coal needs to water in summer, otherwise can spontaneous combustion.Illustrate that thus its composition of solid coal is a carbon, also can discharge carbon monoxide at normal temperatures or under the middle temperature state.We can utilize this characteristic that the solid coal is directly produced coal gas without burning.General industrial production coal gas is coal to be put into sealed vessel heating burn, and feeds certain air and make it produce coke, tar and carbon monoxide.This method must make more than the coal combustion to 800 ℃.And these heat of high temperature are discharged in vain, and heat utilization efficiency is not high.Therefore, be necessary to provide a kind of tool heat conversion height, the device of high safety.

Summary of the invention:

The purpose of this utility model is to provide a kind of a kind of experimental installation that coal is produced carbon monoxide in middle low-temperature condition direct gasification.

The gas producer that the utility model provides is a sealed vessel.Be divided into four layers, the innermost layer is a pressure cooker, in coal cinder is housed, around pressure cooker, wrap resistant to elevated temperatures insulating material plate mica, around plate mica, wrap heating wire plate again, after heating wire plate external parcel insulating cotton, be placed in the shell then, two holes are arranged on high-pressure pot cover, left hole is inserted tempilstick, and the tempilstick top connects thermostat, and right ports connects a flexible pipe as the carbon monoxide venting hole.Below container, there is supply socket can connect power supply.

The utility model can directly produce coal gas by coal without coal combustion and act as a fuel for the user.Experimental box is simple in structure, and is easy to make,, have the heat conversion height, the advantage of high safety utilize the existing resource of school just can make, and the experiment that this teaching aid is done is clear, is good educational aid for school, and good application prospects is arranged.

Below in conjunction with drawings and Examples the utility model is further specified.

Description of drawings:

Fig. 1, structural representation of the present utility model

Embodiment:

The gas producer that the utility model provides as shown in Figure 1, is a sealed vessel.Be divided into four layers, the innermost layer is a pressure cooker 8, in coal cinder 9 is housed, around pressure cooker, wrap resistant to elevated temperatures insulating material plate mica 1, around plate mica, wrap heating wire plate 2 again, after heating wire plate external parcel insulating cotton 3, be placed in the shell 7 then, two holes are arranged on high-pressure pot cover 10, left hole is inserted tempilstick 5, and tempilstick 5 tops connect thermostat 6, and right ports connects a flexible pipe as carbon monoxide venting hole 4.Below container, there is supply socket 11 can connect power supply.

Concrete experimental technique is for putting into pressure cooker 8 with high-quality coal cinder 9 earlier, cover tight pot cover 10 after, connect power supply 11, be heated to 200～300 ℃ with the interior coal fast 9 of 2 pairs of pots of heating wire plate, and monitor with thermostat; Connect a rubber balloon at production well 4 places then, it is big whether observation baloon can become; Can the gas that give off with lighter fulcrum combustion gas ball be seen and be lighted at last.Present method is that coal is heated to below 300 ℃, not burning on burning-point of coal, but it has a large amount of carbon and mixes gasification generation carbon monoxide in back with water vapour between 200～300 ℃, have higher admittedly, the gas transformation efficiency.

Claims

1, a kind of experimental installation of gas producer, it is characterized in that this device is a sealed vessel, be divided into four layers, the innermost layer is pressure cooker (8), around pressure cooker, wrap resistant to elevated temperatures insulating material plate mica (1), around plate mica, wrap heating wire plate (2) again, after heating wire plate external parcel insulating cotton (3), be placed in the shell (7) then, two holes are arranged on high-pressure pot cover (10), left hole is inserted tempilstick (5), tempilstick (5) top connects thermostat (6), and right ports connects a flexible pipe as carbon monoxide venting hole (4), has supply socket (11) can connect power supply below container.
