Abstract
The utility model relates to a dust-collector with a negative pressure regulator. The center of the upper part of a casing of the utility model is provided with a vertical separator plate dividing the right part and the left part of the upper part of the inner cavity of the casing into an inlet chamber and a clean air fog dividing chamber; the lower part of a central partition plate is provided with an S-shaped channel composed of an upper blade and a lower blade and communicated with the clean air fog dividing chamber; an overflow tank is arranged on the bottom of the outer wall of the clean air fog dividing chamber; the top part of an upper chamber of the overflow tank is provided with a pressure regulation pipe communicated with the clean air fog dividing chamber, and is provided with an automatic water level controller; the middle part of the pressure regulation pipe is provided with a negative pressure regulating valve whose opening size is variable. The utility model causes the negative pressure in the overflow tank to be regulated, therefore, the water level in the set is ensured to be balanced to the water level in the overflow tank to ensure the normal operation of the dust collector.
Description
The utility model relates to deduster, and concrete is a kind of deduster that is provided with negative pressure adjusting device.
Use the deduster unit to realize smoke abatement and dust control in fields such as Industrial Boiler, kilns, water level in the deduster unit is by spill box control, during downflow weir in water level exceeds spill box, water level automatic control device is closed automatically, and water just flows to water seal and discharged by overflow pipe.
Because the working site condition is different and other factor, the water level in the unit and the water level of spill box often can not keep balance, make the deduster cisco unity malfunction, influence dust removing effects.
The purpose of this utility model provides a kind of deduster that is provided with negative pressure adjusting device, makes the adjustable size of negative pressure in the spill box, thus the water level in the assurance unit and the balance of spill box water level, the operate as normal of assurance deduster.
The purpose of this utility model is achieved in that
A kind of deduster that is provided with negative pressure adjusting device, its structure comprises that one has the housing of funnel-shaped bottom portion, this housing center upper portion has vertical clapboard with a left side, housing inner chamber top, part on the right side and be divided into inlet plenum and pure qi (oxygen) branch fog chamber, the dusty gas inlet is arranged at inlet plenum top, fusiform blade and lower blade are arranged at the central baffle bottom, on being somebody's turn to do, serpentine channel connection pure qi (oxygen) branch fog chamber is arranged between the lower blade, the bottom surface of this blade is the water-filling waterline, be full of water in housing inner chamber that this waterline is following and the bottom infundibulate inner chamber, the bottom of this funnel inner chamber is provided with sewage draining valve and flushing valve, described pure qi (oxygen) divides the top of going up of fog chamber to be the pure qi (oxygen) outlet, its inwall is provided with the staggered water fender in some positions, its outer wall is by having a spill box, this spill box is divided into upper chamber and lower chambers by diaphragm plate, the upper chamber top has surge pipe to be communicated with pure qi (oxygen) branch fog chamber, and water level automatic control device is housed, the upper chamber bottom has the breather pipe of declivity to stretch in the water of lower housing portion infundibulate chamber, the diaphragm plate of described spill box is provided with the downflow weir of tubulose, and the last plane of this downflow weir is lower than the lower plane of also close water level automatic control device; The sidewall of this spill box lower chambers is provided with overflow pipe, the height of this overflow pipe is higher than the lower end of downflow weir and forms water seal in downflow weir, it is characterized in that: the valve that is equiped with the variable adjusting negative pressure of an openings of sizes at the middle part of the surge pipe of described connection spill box upper chamber and pure qi (oxygen) branch fog chamber.
The utility model has following actively useful effect:
This product is installed a control valve again with the surge pipe enlarged diameter, regulates vacuum magnitude in the spill box according to the different operating situation with valve, to guarantee the water level in the unit and the balance of spill box water level, makes the cleaner operate as normal.
Now in conjunction with the accompanying drawings:
