Description

The utility model relates to ventilation and air purification systems at catering facilities (emissions from barbecues, furnaces, tandoor, etc. equipment) for extinguishing sparks, cooling air, trapping soot and grease, protecting air ducts and chimneys from deposits of soot, grease and preventing fires.

The hydraulic filter is also used in any situations in which it is necessary to cool hot gases and / or air, to clean it of solid particles and / or aerosols, these can be waste and / or fuel burning furnaces, drying chambers, etc. equipment.

Modern technology has brought many benefits to the modern world, but also has led to countless problems. Air pollution, for example, one of the worst effects of modern technology, created a hole in the ozone layer of the atmosphere. In addition, automobile emissions, emissions from factories, as well as emissions from professional kitchens are extremely harmful to our health. This solution is aimed at solving one of the above problems.

The HYDROFILTER according to the patent of the Russian Federation No. 2616914 (priority date 04/06/2016, publ. 04/18/2017 Bull. No. 11) is known. A hydraulic filter containing at least an inlet and outlet pipe body, a water purification unit, a cooling unit, an inertial cleaning unit, a unit dehumidifiers, pump, pipes, valves, automatic control unit, characterized in that the housing is sealed, the inlet and outlet nozzles are located in the upper part of the housing, the water treatment unit contains at least one spray nozzle forming a water curtain, block cooling Denia is a wet maze located horizontally below the level of the water curtain, a water level sensor, a sludge discharge pipe, an overflow pipe, an inertial cleaning unit consists of a layer of water and an impermeable partition located above the water level, the air drainage unit is a dry maze, located horizontally above the outlet of the cleaned air, while in the case a passive protection system is made.

A significant disadvantage of this device is its high aerodynamic drag, in which the system is not possible in passive mode, i.e. in case of an emergency power outage or failure of the fan motor, smoke from the stoves will not be removed and will fall into the serviced room. In addition, there is a deterioration in operating efficiency as the filter mass (Rashig rings) is contaminated, which entails low cleaning efficiency and the reliability of the device as a whole. Also, the constant operation of the pump in dirty water circulating along the recirculation circuit leads to failure of the pump or to its pollution, which requires a major overhaul of the pump.

The purpose of the utility model is to reduce energy consumption, weight reduction, ease of installation, stability of the treatment device, improving the quality of air purification, improving the reliability of the system.

The technical solution is aimed at eliminating the above disadvantages and is achieved through a system of water-air centrifugal filters as part of a single device with a circulating water purification system.

The technical result of the claimed device is the creation of a centrifugal hydraulic filter with increased efficiency and reliability of the device as a whole, which has a higher, controlled degree of cooling and air purification, complete protection against the penetration of sparks and grease into the air ducts and protection of the ventilation system from fire.

The described hydraulic filter comprises a housing, an inlet and an outlet nozzle, a pre-treatment unit, a pre-cooling unit, a water-air centrifugal filter containing at least one nozzle, a water curtain, a droplet eliminator unit, a water tank, a water treatment unit, a pump and an automation control system the operation of the system, as well as the maintenance period.

The utility model is illustrated by diagrams.

In FIG. 1 schematically shows a cross section of a hydraulic filter (branch pipe to the top).

In FIG. 2 schematically shows a cross section of a hydraulic filter (nozzles to the side).

Where 1 - Filter housing; 2 - inlet pipe; 3- Pre-filter formed by a centrifugal labyrinth; 4 - Pre-cooling unit; 5 - Water centrifugal filter; 6 - water pan; 7 - droplet eliminator; 8 - drain pipe; 9 - outlet pipe; 10 - nozzle; 11 - tap direct water supply; 12 - water purification unit; 13 - pump; 14 - make-up valve; 15 - level sensor; 16 - automation system; 17 - discharge pipe skim water; 18 - water-air vortex flow

The hydraulic filter comprises a housing (1), at least an inlet and an outlet pipe (2) and (9) located in the upper part of the housing, can be connected both horizontally in FIG. 1 and vertically in FIG. 2. pre-cleaning unit (3) is a centrifugal labyrinth, which is an air grease trap. The pre-cooling unit (4) and the water-air centrifugal filter unit (5) is a vortex centrifugal separator and contains at least one spray nozzle (10) mounted on the end of the pipe, creating a swirling vortex stream of the water-air mixture. The droplet eliminator unit (7) is a labyrinth that serves to separate and condense moisture from the air, the water purification unit (12) consisting of a reservoir in which filter partitions are located, a pump (13), pipes, shut-off valves, a control and automation unit (16) , the level sensor (15) is used for recirculation and cleaning of the working fluid. Direct feed tap (11) is required to supply water during maintenance and an accident in the electrical part of the device.

The claimed device operates as follows.

Hot air enters the sealed housing (1) of the hydraulic filter through the inlet pipe (2) located in the upper part of the housing, and enters the first stage of air purification. The direction of the air flow at the entrance to the housing can be both horizontal (Fig. 1), and vertical from top to bottom (Fig. 2).

The first stage of cleaning is the passage of air through a labyrinth filter, which traps large particles. Further, air enters the second stage of purification.

The second stage of cleaning is the passage of air through the pre-cooling chamber (4) in which the air is cooled and swirls before entering the centrifugal filter. Then, the swirling air enters the water-air centrifugal filter in which the main cooling and heat-mass transfer (attenuation of sparks) with a swirling water occurs, as well as coagulation of small particles and their displacement to the walls of the centrifugal filter through which the particles are washed off into the pan. This process also contributes to the water curtain formed at the edges of the centrifugal filter. Contaminated water is drained from the pan into a water filter.

Further, the air stream passes through a droplet eliminator, in which moisture is separated and condensed. After the droplet eliminator, air leaves through the outlet pipe (9) in the upper part of the hydraulic filter housing, which can also be directed both to the side (Fig. 1) and up (Fig. 2)

The claimed device is new, since the entire set of features is unknown from the prior art described in the corresponding section of the description.

The claimed technical solution has an inventive step, since it does not explicitly follow from the prior art for a specialist. It is industrially applicable in relation to smoke removal and air purification systems in catering establishments.

As a result, we got a centrifugal hydraulic filter with a simplified design of a lower mass, with increased efficiency and reliability of the device as a whole, which has a higher, controlled degree of cooling and air purification, complete protection against the penetration of sparks and grease into the air ducts and protection of the ventilation system from fire.
