Description
Technical field:
The utility model relates to producer gas generator vaporized chemical " air and steam " flowrate proportioning device, specifically a kind of producer gas generator air-steam flow ratio automatic-adjusting device.
Background technology:
In the producer gas generator production coal gas craft process, particularly important as the flowrate proportioning of the air of vaporized chemical and steam, its can directly influence the gasification degree of coal in producer gas generator.General employing of present stage detects the method for " temperature of saturation " after air and the vapor mixing, comes the flowrate proportioning of indirect control air and steam, realizes adjusting automatically then within the temperature of saturation range of set value.This automatic regulative mode, measuring result can not reflect the flowrate proportioning of air and steam fully, so that the automatic adjusting that tends to make the mistake.Such as, the temperature and the flow of steam all do not change, and air is not under flow changes prerequisite, variation has taken place in its temperature, and should not regulate because the flowrate proportioning of air and steam does not change this moment, but existing " temperature of saturation automatic-adjusting device " can be because detect the variation of temperature of saturation, and wrong automatic adjustment steam flow finally causes " air-steam " flow proportional not meet the requirement of gasification coal, causes the gasification situation in the stove to worsen.This automatic-adjusting device particularly is not suitable for the bigger northern area of day and night temperature, uses this automatic-adjusting device in these areas, and it is normal the day shift working of a furnace to occur through regular meeting, " wondering " phenomenon that the night shift working of a furnace worsens.
Summary of the invention:
Goal of the invention of the present utility model aims to provide a kind of producer gas generator air-steam flow ratio automatic-adjusting device, make as the flowrate proportioning of " air and the steam " of producer gas generator vaporized chemical more accurate, thereby guarantee producer gas generator on the self-regulating basis of realization, the reasonable working of a furnace of long term maintenance.
The technical scheme that realizes the foregoing invention purpose is: this producer gas generator comprises with air-steam flow ratio automatic-adjusting device: an air flowmeter that is installed on the air line, a steam-flow meter that is installed on the steam-pipe, a flow proportional signal processor, the output terminal of this air flowmeter and this steam-flow meter is respectively arranged with the both air flow modulation performer and steam flow is regulated performer, said its flow signal input terminus of this flow proportional signal processor is connected with the flow signal output terminal of this air flowmeter and this steam-flow meter respectively, its flow control signal output terminal is connected with the control signal input terminus of above-mentioned two Flow-rate adjustment performer respectively, and the flow output terminal of two Flow-rate adjustment performer inserts and is the air+vapor mixing pipeline of producer gas generator furnace bottom air blast.
According to this flow proportional automatic-adjusting device that this case realizes, be by detecting air and steam flow and according to the automatic steam regulation flow of air vapor flow proportional set(ting)value, with the automatic-adjusting device of the purpose that reaches stable furnace condition.It sends regulating command by directly measuring air and steam flow behind the contrast scaling signal, carries out corresponding discharge and regulates.It has effectively overcome the existing inaccuracy that automatically adjusts by indirect detection, makes producer gas generator realize that the reasonable working of a furnace of long term maintenance is effectively guaranteed on the self-regulating basis.
Description of drawings:
Fig. 1 is structure of the present utility model and principle of work synoptic diagram.
Embodiment:
Provide a specific embodiment of the present utility model below in conjunction with accompanying drawing.
The described producer gas generator of present embodiment uses air-steam flow ratio automatic-adjusting device by air flowmeter 1, both air flow modulation performer 2, steam-flow meter 3, steam flow is regulated performer 4, flow proportional signal processor 5 constitutes, this air flowmeter 1 and steam-flow meter 3 be installed in respectively on the air line and steam-pipe on, this both air flow modulation performer 2 is set respectively both output terminals and steam flow is regulated performer 4, said these flow proportional signal processor 5 its flow signal input terminuss are connected with the flow signal output terminal of this air flowmeter 1 and this steam-flow meter 3 respectively, its flow control signal output terminal respectively with above-mentioned two Flow-rate adjustment performer 2,4 control signal input terminus connects, two Flow-rate adjustment performer 2,4 flow output terminal inserts and is the air+vapor mixing pipeline 6 of producer gas generator furnace bottom air blast.
The input signal of this device has 10, be used for wherein that device starts, stops, air door is opened, air door closes, steam valve is opened, steam valve closes, the air vapor ratio strengthens, ratio reduces that totally 8 switches are the switching value signal, air flow quantity transmitter, 2 of steam flow transmitters are analog signals; Output signal has 14, wherein indicates 6 of the working station indicators of various piece, and air vapor ratio set(ting)value shows 8, is the switching value signal.
The input function explanation:
Start, stop---being respectively applied for startups, stopping this automatic-adjusting device, adjusting is inoperative automatically when device is not activated, by operator's controlling opening of valve voluntarily.
The air door open and close---regulate the air blast size according to gas consumption.(no matter whether the automatic-adjusting device switch, and this button all works.)
The steam valve open and close---when automatic-adjusting device stops this pushbutton, rule of thumb controlling opening of valve reaches desirable air vapor ratio.
The air vapor ratio strengthens, ratio reduces---and press the air vapor ratio respectively and strengthen, reduce button, can change the air vapor ratio, improve gas quality according to coal.
Quantity, type and control requirement according to the I/O signal increase used input/output point on the basis of the used PLC of original stoker, select the FX2N-64MT main frame, and two tunnels analogy amount load module FX-2AD can satisfy the control requirement; Air flowmeter 1 and steam-flow meter 3 are selected the known products of sky, Tangshan occasion electrical apparatus factory respectively for use---L, Z type elbowmeter; Both air flow modulation performer 2 and steam flow are regulated known products---the electrically operated valve that performer 4 is selected Tianjin Bel's self-service instrument factory for use; Flow proportional signal processor 5 adopts Mitsubishi PLC and special functional module thereof to realize design function.
