Abstract
The invention provides a slurry feeding device for coal water fuel or peat slurry boiler, installed on top of the boiler and composed of cooling air inlet cylinder, air inlet connection pipe, fire observing mirror, slurry inlet pipe, dredging hole with closed bolt, blowing-washing pipe, coal water fuel granulating pipe, etc. The coal water slurry or peat slurry washing/blowing pipe is arranged on the coal water fuel granulating pipe, the top end of the coal water fuel granulating pipe is made with a dredging hole for being convenient to dredge; the whole set of coal water fuel granulating pipe is arranged in the cooling air pipe (box); the fire observing mirror is arranged on the cooling air pipe (box) for observing the conditions of feeding and combusting as operating, and the slurry feeding device is directly connected with the slurry feeding pipeline and effectively solves the problems that the current coal water fuel or peat slurry combusting system is complex, the slurry gun is easy to block and burn out, the reliability is bad and the maintaining quantity is heavy.
Description
Technical field:
The invention belongs to a kind of water-coal-slurry or mud coal slurry boiler and give sizing device.
Background technology:
Water-coal-slurry or mud coal slurry are a kind of novel coal-based fluid clean fuels, it has can pipeline carries, stores advantages such as totally-enclosed, cheap, the energy-conservation and environment protecting of transportation is good, can be widely used in Industrial Boiler, civil boiler, Industrial Stoves and station boiler.Water-coal-slurry or mud coal slurry are as a kind of generation oil fuel, system complex, slurry rifle are easily stifled, uneven for slurry because flow inlet road and slurry rifle exist, poor combustion stability and efficiency of combustion is low, maintenance workload big, in the running to the problems such as reliability requirement height of boiler accessory machinery, limited the extensive use on industry and civil boiler of water-coal-slurry or mud coal slurry.
Summary of the invention:
The objective of the invention is to provide a kind of water-coal-slurry with mediation and refrigerating function or mud coal slurry boiler to sizing device.
Technical scheme of the present invention realizes by following manner.
A kind of is that the boiler of fuel is given sizing device with water-coal-slurry or mud coal slurry; be installed in the top of water-coal-slurry or mud coal slurry boiler, it is characterized in that constituting by parts such as cooling air air intake tube connector, flame-observing mirror, water-coal-slurry pulp-inlet pipe, the dredging hole that has blind bolt, purging scavenge pipe and water-coal-slurry granulating pipes.Water-coal-slurry or mud coal slurry are housed on the water-coal-slurry granulating pipe clean scavenging conduit (but water receiving or compressed air), dredging hole is left on the top of water-coal-slurry granulating pipe, with convenient mediation, should seal when operation; A whole set of water-coal-slurry granulating pipe places in cooling duct or the cool wind box; Flame-observing mirror is equipped with in inside or outside at cooling duct or cool wind box; burning when observing operation and give the slurry situation; this device directly is connected with the flow inlet road; by this device water-coal-slurry granulation pulping is dripped; burn in the combustion chamber of sending into boiler equably, the stability of boiler combustion and efficiency of combustion are improved.
Description of drawings:
Fig. 1 is the structural representation that has the mediation and the water-coal-slurry of refrigerating function or mud coal slurry boiler to sizing device according to provided by the present invention.
The specific embodiment:
In order further to disclose technical scheme of the present invention, be further elaborated below in conjunction with drawings and Examples.
As shown in Figure 1, this device mainly by cooling air air intake tube 1, cooling air air intake tube connector 2, flame-observing mirror 3, water-coal-slurry pulp-inlet pipe 4, have blind bolt dredging hole 5, purge scavenge pipe 6 and water-coal-slurry granulating pipe 7 constitutes, the water-coal-slurry that uses enters the water-coal-slurry granulating pipe through pulp-inlet pipe and is granulated into and drips a shape cluster of grains and fire burns; For preventing that the water-coal-slurry dehydration of being heated from solidify stopping up granulating pipe, be with a cooling air air intake tube (case) 1 in the outside of granulating pipe, the source of cooling air is the boiler air-supply.Water-coal-slurry granulating pipe 7 is biased in the cooling air air intake tube 1, its objective is to utilize the wind speed difference of same cross section cooling air in the air duct that water-coal-slurry granulation pulping is dripped, and also be the installation slot milling of flame-observing mirror simultaneously; Flame-observing mirror 3 is contained in the cooling air air intake tube, and eyeglass is made with quartz glass; On granulating pipe 7, be equipped with and purge scavenge pipe 6, so that boiler cleans or purges with anti-clogging after stopping using; Dredging hole (sealing with bolt during operation) also is housed at the top of water-coal-slurry granulating pipe, with mediation because other blockage problem former thereby granulating pipe that causes.
This device does not need giving of other to starch auxiliary device and filter plant, can directly be connected with water-coal-slurry or mud coal stock pump.This device does not have specific (special) requirements to the parameter of water-coal-slurry or mud coal slurry, its main feature is: give the slurry stable and uniform, flameholding, be difficult for stopping up and burning out, applied widelyly (be suitable for different grain size, concentration, ash, isoparametric water-coal-slurry of fugitive constituent or mud coal slurry) and system simple and reliable, be convenient to operation, solved present water-coal-slurry or mud coal slurry combustion slurry system complex effectively, the easily stifled easy burn-out of slurry rifle, poor reliability, the problem that maintenance workload is big can be widely used in industry, the water-coal-slurry of domestic use of water coal slurry or mud coal slurry boiler and oil burning boiler or mud coal slurry transformation.
Claims (4)
