Abstract
The invention discloses an anti-plugging system of a nozzle for a GGH (Gas-gas Heater) washing device. The anti-plugging system is composed of an anti-plugging reverse blower I, an anti-plugging reverse blower II, an anti-plugging reverse-blowing electrically operated valve, manually operated valves, one-way valves, an upper washing device, a lower washing device and nozzles; the upper washing device and the lower washing device respectively correspond to one set of the manually operated valve, the one-way valve and the nozzle; the nozzles, the washing devices, the one-way valves and the manually operated valves are sequentially connected in series through pipe fittings; the anti-plugging reverse-blowing electrically operated valve is respectively connected to the two manually operated valves through the pipe fittings; and the anti-plugging reverse blower I and the anti-plugging reverse blower II are connected to the anti-plugging reverse-blowing electrically operated valve through the pipe fittings. In the invention, the anti-plugging system of the nozzle for the GGH washing device can guarantee that the nozzle of the washing device is not plugged, thus the washing efficiency is improved.
Description
Technical field
The present invention relates to the anti-blocking system of a kind of nozzle, refer in particular to a kind of GGH cleaning device anti-blocking system of nozzle.
Background technology
When GGH is in operation and stops using, all be equipped with a cover cleaning device.Because the working environment of this equipment is relatively poor, contains more ash in the former flue gas, clean flue gas contains more gypsum impurity, so nozzle is easy to stop up, after the obstruction, needs to shut down, and manually pulls down nozzle cleaning or replacing.
Summary of the invention
The problem to be solved in the present invention is the deficiency that overcomes in the background technology, a kind of GGH cleaning device anti-blocking system of nozzle is provided, and this system purges under the situation about not putting into operation at cleaning device, the valve that system opens anti-blocking system automatically makes the air blowback to nozzle, prevents to stop up.
For addressing the above problem, the present invention takes following technical scheme:
The anti-blocking system of a kind of GGH cleaning device usefulness nozzle of the present invention is made up of anti-blocking back blowing machine I, anti-blocking back blowing machine II, anti-blocking blowback wind-powered electricity generation movable valve, hand-operated valve, check valve, last cleaning device, following cleaning device, nozzle; Each corresponding cover hand-operated valve, check valve and nozzle of last cleaning device and following cleaning device; Nozzle, cleaning device, check valve, hand-operated valve are cascaded with pipe fitting in order, and anti-blocking blowback electrically operated valve is connected to two hand-operated valves respectively by pipe fitting, and anti-blocking back blowing machine I, anti-blocking back blowing machine II are connected to anti-blocking blowback electrically operated valve by pipe fitting.
A kind of GGH cleaning device of the present invention can guarantee that with the anti-blocking system of nozzle the purging system nozzle does not stop up, and has improved cleaning performance.
Description of drawings
Fig. 1 is a framework schematic diagram of the present invention.
The specific embodiment
As shown in Figure 1, the anti-blocking system of a kind of GGH cleaning device usefulness nozzle of the present invention is made up of anti-blocking back blowing machine I, anti-blocking back blowing machine II, anti-blocking blowback wind-powered electricity generation movable valve, hand-operated valve, check valve, last cleaning device, following cleaning device, nozzle; Each corresponding cover hand-operated valve, check valve and nozzle of last cleaning device and following cleaning device; Nozzle, cleaning device, check valve, hand-operated valve are cascaded with pipe fitting in order, and anti-blocking blowback electrically operated valve is connected to two hand-operated valves respectively by pipe fitting, and anti-blocking back blowing machine I, anti-blocking back blowing machine II are connected to anti-blocking blowback electrically operated valve by pipe fitting.
Anti-blocking back blowing machine II is a standby fan.
