The reaction in the gas reaction vessel 8 is a continuous process, and the high-temperature fire layer becomes low in temperature after the reaction is finished and is converted into an ash layer to move downwards. Under the action of the grate, the gas is discharged in a timed and quantitative manner according to the position of the gas reaction container 8 and the process requirements given by a computer system. And the dry distillation layer connected with the upper part of the fire layer is also gradually reacted into the fire layer under the influence of the high temperature of the fire layer and gradually moved downwards to react with the gasification agent to produce coal gas. The method is a whole reaction process for continuously and circularly generating coal gas from top to bottom; the bottom fire grate is arranged on a rotatable chassis 15 with a basin seal at the lower part of the gas reaction container 8, and a large pan wheel is fixedly arranged on the outer ring of the chassis 15 and is directly driven by a pan rod.

the laser distance measuring system 2 is a set of system for measuring the position of a high-temperature reactant in the gas reaction vessel 8 and is arranged at the top of the gas reaction vessel 8. Because the gas in the reaction vessel 8 is at a high temperature for a long time, it is not a continuous measurement.

The fully-closed and fully-intelligent coal gas-making equipment is realized and serves various industries.
The design of the utility model reduces the number of operators by more than 70%, reduces the labor intensity, improves the working environment and can realize unmanned operation and remote control; because the timing drill rod water detecting process is cancelled, the quality of the coal gas in the furnace is improved by more than 10 percent; the computer can timely and reliably adjust each operating mechanism and accurately adjust the saturation temperature and the like according to a large amount of collected data, so that the optimal state is always processed in the furnace; completely eliminating the experience that the coal gas making system is trapped for a long time and the fire is detected by manually inserting fibers to judge whether the slagging is caused in the furnace or not and the quality problem of the coal gas; because the danger of gas leakage does not occur because the high-pressure steam is needed for fire detection without inserting a drill rod, the operating pressure of the pressure container of the main body water jacket is greatly reduced, and the equipment is safer and more reliable.
It will be apparent to those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention. Thus, if such modifications and variations of the present invention fall within the scope of the claims and their equivalents, the present invention is also intended to include such modifications and variations.
