Abstract

The utility model relates to a coal tar addition and powder discharge system for a continuous molded coal gasifying fixed bed, which comprises a large storage bin, a decompression device, a vibration sieving powder feeding machine and a powder discharge spout. The coal tar addition and powder discharge system is characterized in that the vibration sieving powder feeding machine is also arranged below the large storage bin; the large storage bin is positioned above the vibration sieving powder feeding machine; the decompression device is connected below the large storage bin; the vibration sieving powder feeding machine is connected with the decompression device in a flexible connection manner; the vibration sieving powder feeding machine comprises a rear vibration damper, an electromagnetic vibrator or a motor vibrator, a front vibration damper and a trough; and a powder sieving device is arranged in the trough. The coal tar addition and powder discharge system is provided with a powder sieving and powder discharge device, and can basically prevent coal powder from entering a gas-making furnace, thereby improving the gas production efficiency and yield; on the other hand, the recollected coal powder also can be recycled, thereby conforming to the national industrial policies of recycling economy and energy conservation and emission reduction, and greatly improving the corporate profitability.

Description

Moulded coal continuous gasification fixed bed coke charging powder exhaust system
Technical field:
The utility model relates to a kind of moulded coal continuous gasification fixed bed coke charging powder exhaust system.
Background technology:
The continuous producer of existing coal oxygen enrichment is not because feed coal passes through the operation that screens out of fine coal, enter that existing moulded coal has fine coal again in the old feed coal of body of heater, and fine coal enters producer and can produce serious negative impact to the production of coal gas, have a strong impact on system gas output, can stop up outlet pipe again, produce a large amount of dust and pollute discharging.
The utility model content:
The purpose of this utility model is to provide can effectively be eliminated fixed bed moulded coal oxygen enrichment that fine coal enters body of heater and make gas continuously and add burnt row's powder system.
The technical solution of the utility model is as follows: it is made of big material bin, reliever, vibratory screening apparatus powder feeding machine, row's powder elephant trunk, it is characterized in that: also be provided with vibratory screening apparatus powder feeding machine below big material bin; Big material bin is positioned at the top of vibratory screening apparatus powder feeding machine, and the below of big material bin is connected with reliever, and vibratory screening apparatus powder feeding machine is connected by the mode that is flexible coupling with reliever; Vibratory screening apparatus powder feeding machine is made of rear shock absorber, electromagnetic vibrator or motor oscillating device, preceding vibroshock, hopper; In hopper, be provided with sieve powder device.
The utility model is provided with sieve powder, row's powder device, can stop fine coal substantially enters in the Gas-making Furnace, thereby gas production efficient and output have been improved, on the other hand, again collected fine coal again can cycling and reutilization, meet recycling economy, the national industrial policies of energy-saving and emission-reduction have greatly improved the benefit of enterprise.
Description of drawings:
Fig. 1 is the one-piece construction synoptic diagram of a kind of embodiment of the utility model.
Label declaration: vibroshock, 7 hoppers, 8 grating lower supports, 9 gratings, 10 row's powder elephant trunks, 11 emission of baiting chute, 12 distributors before 1 big material bin, 2 vibratory screening apparatus powder feeding machines, 3 rear shock absorbers, 4 electromagnetic vibrators or motor oscillating device, 5 relievers, 6.
Embodiment:
As shown in Figure 1, the utility model has been set up vibratory screening apparatus powder feeding machine 2, row's powder elephant trunk 10 for 1 time at existing big material bin;
(a) big material bin is positioned at the top of vibratory screening apparatus powder feeding machine, and the below of big material bin is connected with reliever, and vibratory screening apparatus powder feeding machine is connected by the mode that is flexible coupling with reliever 5;
(b) oscillating feeder is made of rear shock absorber, electromagnetic vibrator or motor oscillating device, preceding vibroshock, hopper; Rear shock absorber 3 is located on electromagnetic vibrator or the motor oscillating device 4, and electromagnetic vibrator or motor oscillating device are connected with hopper 7, and preceding vibroshock 6 is connected with hopper;
(c) side in hopper is provided with sieve powder device, is connected with row's powder elephant trunk 10 by the mode that is flexible coupling below sieve powder device, is connected with emission of baiting chute 11 by the mode that is flexible coupling below hopper opposite side discharge port;
(d) sieve powder device is made of grating lower support 8 and the grating that is fixed on grating 9 lower supports, the transverse section of described grating is up big and down small to fall trapezoidal or upside-down triangle shape or other shape, grating divides two sections vertical distributions and leading portion to omit high than back segment along the below of big material bin to the direction of vibratory screening apparatus powder feeding machine discharge port, perhaps single hop vertically distributes, and the grating gap width is changed from small to big along above-mentioned direction and is trapezoidal arrangement or equidistantly arranges; The grating gap becomes 12mm from 8mm in two sections in front and back.This trapezoid grating structure lump coal passes through easily, is not easy to result in blockage.
The working process of the utility model system implementation is as follows: after fine coal enters from big material bin, by reliever 5, blanking is to the sieve powder device of vibratory screening apparatus powder feeding machine, through the powder device screening of sieving, screened out and separated less than the coal dust of grating gap size from row's powder elephant trunk, under the control of PLC (programmable logic controller) Controlling System, lump coal up to specification is under the effect of vibratory screening apparatus powder feeding machine, give gradually from the leading portion grating and to expect the back segment grating, discharge port through vibratory screening apparatus powder feeding machine enters distributor 12 then, by distributor 12 the lump coal raw material is dropped in the Gas-making Furnace at last; Perhaps the discharge port of vibratory screening apparatus powder feeding machine enters distributor 12 by the blanking chute, and last big distributor 12 drops into the lump coal raw material in the Gas-making Furnace.
