Description
Technical Field
The utility model relates to the field of sewage treatment, in particular to a cyclone three-phase separator suitable for a UASB reactor.
Background
UASB reactor principle: sewage water is uniformly introduced into the bottom of the reactor, and the sewage water passes upward through a sludge bed containing granular sludge or flocculent sludge. Anaerobic reactions occur during the process of contacting wastewater with sludge particles. Biogas (mainly methane and carbon dioxide) produced in an anaerobic state causes internal circulation. Some of the gas formed in the sludge layer adheres to the sludge particles and the gas, both adhering and not adhering, rises towards the top of the reactor. The sludge rising to the surface hits the bottom of the three-phase reactor gas emitter, causing deaeration of the sludge flocs with attached bubbles. The sludge particles will settle to the surface of the sludge bed after the release of the bubbles and the gas, both attached and unattached, is collected in the gas collection chamber of the three-phase separator at the top of the reactor.
The traditional three-phase separator is mostly arranged in parallel, and although the structure is simple, the mud-water separation condition is poor, two liquid flows which rise and fall simultaneously exist at a backflow seam, the mutual interference is caused, the sludge backflow is not smooth, the sludge leakage is serious, the UASB reactor needs to be periodically supplemented with the sludge, and the material resources and the labor cost are increased. The sludge returned by the traditional three-phase separator is settled back to the reaction zone by natural gravity, and can be combined with biogas bubbles again to rise to the three-phase separator in the settlement process, or rise to the three-phase separator by the action of local water force, so that the action of activated sludge is difficult to play. The phenomenon of local sludge deposition and dead zone which are easily caused by uneven distribution of settled sludge.
The conventional three-phase separator has the following drawbacks:
1. poor mud-water separation condition, serious mud leakage is caused, so that the UASB reactor needs to be periodically supplemented with mud, and material and labor costs are increased.
2. The sludge may be combined with biogas bubbles again in the sedimentation process to rise to the three-phase separator, so that the effect of the activated sludge is difficult to play.
3. And (3) a phenomenon of local deposition and dead zone of the sludge caused by uneven sludge distribution.
Disclosure of Invention
Accordingly, in order to solve the above-mentioned shortcomings, the present utility model herein provides a cyclone type three-phase separator suitable for use in a UASB reactor. The device overcomes the phenomenon of mud leakage of the traditional three-phase separator, and performs secondary distribution on the return mud, so that the mud can fully contact with the waste water from the bottom, and the phenomenon of local sedimentation and dead zone of the mud caused by uneven mud distribution is solved.
The utility model is realized in such a way that a cyclone three-phase separator suitable for a UASB reactor is constructed, which is characterized in that; the cyclone three-phase separator comprises a gas-water separation cover, guide vanes (1) are arranged around the gas-water separation cover, a sedimentation area is formed by an area surrounded by each guide vane, an air chamber (2) is formed by a lower area corresponding to the gas-water separation cover, and an exhaust hole (3) is formed in the gas-water separation cover, and each guide vane is partially overlapped.
The utility model has the following advantages: 1. the mud-water separation effect is optimized, the mud leakage condition is reduced, the mud supplementing amount is reduced, and the material and manpower costs are reduced. 2. The condition that the sludge is combined with biogas bubbles again to rise in the sedimentation process is avoided and reduced, and the effect of the activated sludge is fully exerted. 3. The secondary distribution is carried out on the returned sludge, so that the sludge is fully contacted with the wastewater from the bottom, and the phenomena of local sludge deposition and dead zone caused by uneven sludge distribution are solved.

The utility model provides a cyclone three-phase separator suitable for a UASB reactor through improvement, wherein the three-phase separator is a core component of the reactor, directly influences the gas, liquid and solid separation effect of the reactor, and can be used for high-concentration wastewater treatment engineering. As shown in the figure, the cyclone three-phase separator comprises a gas-water separation cover, guide vanes 1 are arranged around the gas-water separation cover, a sedimentation area is formed by an area surrounded by each guide vane, an air chamber 2 is formed by a lower area corresponding to the gas-water separation cover, an exhaust hole 3 is arranged on the gas-water separation cover, and each guide vane is partially overlapped. The device overcomes the phenomenon of mud leakage of the traditional three-phase separator, and performs secondary distribution on the return mud, so that the mud can fully contact with the waste water from the bottom, and the phenomenon of local sedimentation and dead zone of the mud caused by uneven mud distribution is solved.
The control principle of the utility model is as follows:
the guide vanes of the sedimentation zone are radially arranged around the gas-water separation cover, the sewage slightly rotates when passing through, and some gas formed by biogas (mainly methane and carbon dioxide) on the sludge layer adheres to sludge particles, and the adhered gas and the unattached gas rotate to rise to the top of the reactor. The sludge rising to the surface hits the bottom of the guide vane of the three-phase reactor, causing the sludge flocs attached with bubbles to be deaerated. The sludge particles are deposited on the surface of the sludge bed along with the rotation of the water flow after the release of the bubbles, and the gas which is attached and not attached is collected into a gas collection chamber of a three-phase separator at the top of the reactor.
