Abstract

The utility model relates to a fixed grate of a coal-gas generating furnace, which is composed of a top cap (1), a grate plate of a second layer (2), a grate plate of a third layer (3), a grate plate of a fourth layer (4), a grate plate of a fifth layer (5), a base (6), and screw bolts (7), wherein, the grate plates, as well as the grate plates and the base, are connected with each other by the screw bolts. The grate forms a cone shape. Each grate plate is respectively provided with an ash discharging and slag breaking ribs (8) which rotate anticlockwise, and both ends of each ash discharging and slag breaking rib protrude and form a Yuanbao shape. The grate plate of each layer is respectively provided with an inwards folding edge and an outwards folding edge. The outer circle of the grate plate of the fifth layer (5) and the outer circle of the base (6) both form a wave shape. The grate can improve the gas production rate, reduce consumption, decrease things which are brought out, reinforce the capability of breaking slag, and reduce the abrasion of equipment.

Description

The simple stationary gas producer fire grate
The utility model belongs to chemical mechanical equipment, is specifically related to a kind of simple stationary gas producer fire grate.
Up to the present, what the key part fire grate of 3.6 meters simple stationary gas producers of domestic Φ all used is the producer fire grate of the fifties USSR (Union of Soviet Socialist Republics) design, does not do big change.
3.6 meters simple stationary gas producers of a Φ were used for synthetic ammonia, the production of methanol feedstock gas surplus the existing whole nation had 40.According to production service condition for many years, the subject matter that this fire grate exists is as follows: (this fire grate specification: Φ 2900mm, H1325mm, draught area 1M 2, gross weight: 7.9 tons)
1, it is many to blow over the journey carry-over under the fire grate, every stove about 5-6 ton every day, the serious obstruction, wearing and tearing are the steel pipe of blowpipe road thickness 16mm down, and only using just galled half a year needs to repair or change, after use the thick cast-iron pipe of 30mm instead, life cycle is prolonged, increased investment cost; Simultaneously, carry-over makes gas making recirculating cooling water system ash many more, causes the water pump serious wear, and maintain and replace is frequent, and the settling tank ash quantity of slag is big, and scarfing cinder labour intensity is big.
2, this fire grate dreg-breaking performance is poor, causes the deslagging difficulty, and the bed gas distribution is inhomogeneous, slagging scorification easily, and often clinker is taken off in blowing out, needs switch-off to handle when serious.
3, because the structure design of this fire grate is unreasonable, cause draught area little, be difficult to improve gas production rate.
4, consume height, the coke return rate height, ash content carbon is up to about 20%.
In recent years, domestic improvement technology to 3.6 meters simple stationary gas producer fire grates of Φ:
The uniform distribution type of domestic-developed and spiral type fire grate use on 3 meters immovable bed Gas-making Furnace of Φ, though have than successful experience, test all has problems on 3.6 meters immovable bed Gas-making Furnace of Φ.
1, the subject matter of Uniform Distribution Grate existence is: three layers and four layers of obstruction of fire grate, and dreg-breaking performance does not strengthen, and consumes yet to reduce, and gas production rate does not have obviously to improve.
2, helicon fire grate, because of its design problem, 3.6 meters stoves of Φ are on probation does not succeed yet.
The purpose of this utility model is exactly at above-mentioned the deficiencies in the prior art, a kind of output that improves simple stationary gas producer is provided, reduces consuming, reduce carry-over, strengthen the dreg-breaking performance of fire grate, alleviate the simple stationary gas producer fire grate that equipment and pipe wear are equal to topic.
The purpose of this utility model can realize by following measure: the utility model is made up of grate plate and base, be connected with the layer 5 grate plate by bolt on the base, be connected with the 4th layer of grate plate by bolt on the layer 5 grate plate, be connected with the 3rd layer of grate plate by bolt on the 4th layer of grate plate, be connected with second layer grate plate by bolt on the 3rd layer of grate plate, connect crown cap by bolt on the second layer grate plate; Second layer grate plate is to the taper that is shaped as of layer 5 grate plate, the pitch angle of taper is 15 °-20 °, be equipped with the ash discharge rib-breaking rib that rotates by counterclockwise on every layer of grate plate, outstanding be " ingot-shaped " in ash discharge rib-breaking rib two ends, every layer of grate plate all are provided with inside and outside flanging and for increasing the taper hole of draught area; The even undaform that is made as of the cylindrical of layer 5 grate plate and base.
The boss that reaches Bolt Connection place between layer 5 grate plate and the base between above-mentioned every layer of grate plate all is located at the inner of rib camber line, and is provided with groove.
The utlity model has following advantage:
1, fire grate gas distribution Uniform Ventilation, it is smooth and easy to ventilate, and does not have latch up phenomenon;
2, break is strong, slagging rate height, and ash discharge is smooth and easy;
3, carry-over is few, reduce more than 70%;
4, gas production rate can improve more than 8%, and the steam rate of decomposition improves 5%, and coke return rate falls 5%;
5, maintenance, easy for installation.
