and the control system is used for deciding and controlling through a valve, and sending the waste gas treated by the cooling and dehydrating system into one path so as to treat the waste gas treated by the cooling and dehydrating system through the path.
The exhaust air supply system 110 includes, but is not limited to, organized and unstructured exhaust air supply fans in the food industry, the feed industry and the pharmaceutical (containing Chinese herbal medicine decoction pieces or western medicine decoction pieces) production industry, and the fans include axial fans and centrifugal fans configured in the existing production system, and also include axial fans and centrifugal fans introduced for balancing air volume and air pressure in environmental protection treatment. That is, the exhaust air delivery system 100 may be adapted for use in a variety of different applications, producing a variety of materials in a variety of functions, followed by filtration, purification, and the like.
The dust removing system 120 is connected with the exhaust air supply system 110, and the dust removing system 120 receives the exhaust air discharged by the exhaust air supply system 110 and reduces the dust degree thereof. In the dust removal system 120, dust acts as an important carrier for odor molecules, playing a critical role in the transmission and diffusion of odors, and therefore dust removal is required to reduce the concentration of odors. The dust removal system 120 is provided for the purpose of reducing dust in the emitted organized, non-organized exhaust gas; because the waste gas has the characteristics of high temperature, moisture and oil, the dust fall treatment is mainly carried out by adopting a pulse dust collector or a plastic-sintered plate (also called a sintering plate) dust collector of a water-repellent and oil-proof filter bag. The filter bag dust remover and the plastic plate dust remover are both provided with pulse blowing devices, and dust adhered on the filter bag and the plastic plate is cleaned regularly, so that the dust removing effect is ensured, and the good stability of operation is ensured. The dust remover and the air inlet pipeline are subjected to heat preservation treatment, so that condensate water is prevented from being generated, and the service life of the dust removal filter material is prolonged.
The cooling and dewatering system 130 is connected with the dust removing system 120. The cooling and dehydrating system 130 receives the exhaust gas discharged from the dust removing system 120 and performs cooling and dehydrating thereon. In the cooling and dehydrating system 130, since water molecules are also one of the important carriers of the odor molecules, and the high temperature can aggravate the spread and diffusion of the odor, it is necessary to cool and dehydrate the exhaust gas to further reduce the concentration of the odor. At the same time of cooling and dewatering, dust which cannot be removed by the dust removal system 120 is reduced, and the control and subsequent treatment of peculiar smell are decisive. The system mainly relates to equipment such as a heat exchanger, a water chiller, an evaporative condenser, a cooling tower, a transfer water tank, a water pump, a pipeline valve and the like.
The heat exchanger has the main functions of cooling and dehydrating the waste gas, and can adopt a gas-gas heat exchanger and a gas-liquid heat exchanger. The gas-gas heat exchanger uses ambient air as a cooling medium to cool the waste gas, mainly plays a role in pre-cooling, and the applicable temperature of the waste gas is higher than 60 ℃. The gas-liquid heat exchanger mainly uses the refrigerating fluid as a cooling medium to cool the waste gas, and can be used for pre-cooling and deep cooling treatment. The frozen liquid can be directly purchased into low-temperature liquid media such as ice water, liquid nitrogen and the like, and can also be prepared by equipment such as a chiller, an evaporative condenser or a cooling tower and the like. And outsourcing ice water and liquid nitrogen are conveyed to the heat exchanger through the pump valve to cool the waste gas and then are discharged, wherein the ice water can be used as production water, and the temperature of the liquid nitrogen is increased to be volatilized gas, so that the environment is not influenced. The prepared chilled water is conveyed to a heat exchanger through a water pump to cool the waste gas and then returns to a transfer water tank, and is cooled by a water chiller and recycled. Several methods for preparing chilled water are provided below:
Preparation method of chilled water 1:
adopts a water chiller (comprising a condenser), a spray tower, a water pump, a pipeline and other devices. The refrigerant (also referred to as "refrigerant") absorbs heat from the cooled liquid in the evaporator and evaporates into vapor, and the cooled liquid forms chilled water which cools the exhaust gas through the heat exchanger. The compressor continuously draws and compresses the generated vapor from the evaporator. The compressed high-temperature and high-pressure steam is sent to a condenser and then is discharged to water for heat condensation to form high-pressure liquid, the high-pressure liquid is reduced in pressure by a throttling mechanism and then enters an evaporator for vaporization again, and the heat of the cooled liquid is absorbed; the water after temperature rising is conveyed to a cooling tower through a water pump to cool and then returns to a condenser to cool the refrigerant, and the operation is repeated.
Preparation method 2 of chilled water:
adopts a water chiller (without a condenser), an evaporative condenser and other devices. The evaporative condenser integrates a shell-and-tube water-cooled condenser, a cooling tower, a circulating water pump, a water tank and a water pipeline. The superheated high-pressure refrigerant gas discharged from the compressor in the water chiller passes through a condensing calandria in the evaporative condenser, so that the high-temperature gaseous refrigerant exchanges heat with spray water and air outside the calandria to be recycled to the evaporator of the water chiller, the heat of the cooled liquid is absorbed and vaporized into steam again, and the cooled liquid forms chilled water to cool the waste gas through the heat exchanger. Compared with the traditional cooling tower, the evaporative condenser has the advantages of compact structure, small occupied area, light weight, few connecting pipelines, convenient installation and the like, and meanwhile, the power of the compressor is saved by at least 10 percent compared with other cooling tower/condenser systems, and the operation cost is lower.
The application of ice cold accumulation in cooling: in order to optimize the electricity consumption, the refrigerating capacity required by daily exhaust emission treatment is ensured by the preparation methods 1 and 2 of the chilled water for valley electricity and flat electricity at night and storing the chilled water in a large enough transfer water tank, so that the uninterrupted operation of an environmental protection system is ensured. The preparation methods 1 and 2 of the chilled water are controlled in an optimized mode, so that the preparation efficiency of the product is effectively improved.
The stack exhaust system 140 controls the exhaust treatment system 100 in a micro-negative pressure state as an exhaust gas discharge system. Further, the stack exhaust system 140 includes an exhaust stack, an induced draft fan, and a wind pressure sensor. The exhaust chimney, the sampling hole and the adoption of the platform are arranged to meet the requirements of the technical Specification for monitoring fixed source exhaust gas (HJT 397). The induced draft fan is mainly arranged for balancing the air quantity and the air pressure of the environment-friendly treatment system, so that the environment-friendly equipment can be ensured to effectively operate. The chimney discharge system 140 is provided with a wind pressure sensor and alarm feedback, monitors the wind pressure value on line and feeds back the regulating system in a micro negative pressure state.
As shown in fig. 2, 3 and 4, the first dust sensor 210 is connected to the dust removing system 120 and the cooling and dewatering system 130, and the first dust sensor 210 is used for monitoring the dust removing degree of the dust removing system 120 in real time. The first pressure sensor 220 is connected to the dust removing system 120, the first dust sensor 210 and the cooling and dewatering system 130, and the first pressure sensor 220 is used for monitoring the pressure of the dust removing system 120 in real time.

Meanwhile, a first dust sensor 210, a first pressure sensor 220 and alarm feedback are provided, the dust removal effect and the pressure difference condition are monitored in real time, and the feedback is timely carried out when a fault occurs.
The first temperature and humidity sensor 230 is connected to the cooling and dehydrating system 130, and the first temperature and humidity sensor 230 is used for detecting the temperature and humidity of the cooling and dehydrating system 130. The sewage treatment system 240 is connected with the cooling and dewatering system 130, and the sewage treatment system 240 is used for receiving the condensed sewage discharged by the cooling and dewatering system 130 and treating the condensed sewage until reaching the discharge standard. The temperature and humidity state of the biological filter bed system is monitored through the first temperature and humidity sensor 230, so that the biological strains are ensured to have higher biological activity under the proper temperature and humidity conditions, and the deodorizing efficiency is improved. Meanwhile, the working pressure of the system is monitored through the second pressure sensor 293 and alarm feedback, whether the packing system is collapse or not is monitored, and stable operation of the processing system and convenience in daily maintenance and management are ensured. In the sewage treatment system 240, the sewage removed in the cooling and dewatering system 130 is treated by sewage treatment equipment to reach the standard and then reused as production water or plant greening water, and is not discharged. Because the biodegradability of the wastewater is good, a treatment process of anaerobic fermentation and an activated sludge method is adopted. The treated sewage reaches the second-level emission standard of pollutant emission standard of urban sewage treatment plant (GB 18918-2002). The sewage treatment execution standard is as follows
The oxidation and deodorization system 250 is connected with the cooling and dehydration system 130, and the oxidation and deodorization system 250 comprises an ozone generator, a photocatalytic oxidation and deodorization device and a low-temperature plasma deodorization device and is used for sterilizing waste gas and harmful organisms of products in the cooling and dehydration system 130. Oxidation deodorization system: the oxidation deodorization system herein may employ one of an ozone deodorization device, a photocatalytic deodorization device, and a low-temperature plasma deodorization device.
An ozone generator: an apparatus for producing ozone gas (O3). Ozone is easy to decompose and inconvenient to store, so that the ozone needs to be prepared and used on site. There are three main forms, the first is a high voltage discharge type, the second is an ultraviolet irradiation type, and the third is an electrolysis type. The main control parameters include ozone generation amount, ozone concentration, discharge voltage, power, air treatment medium, etc. Ozone has extremely strong oxidizing power, the oxidation-reduction potential is inferior to that of fluorine, and organic or inorganic substances generating odor and other odors can be rapidly decomposed by virtue of the strong oxidizing property.
Photocatalytic oxidation deodorization equipment: when photons with the wavelength below 253.7nm are irradiated on the photocatalyst titanium dioxide particles under the irradiation of a UV ultraviolet light lamp, electrons of the catalyst in a valence band are excited by the photons, and transition to a conduction band to form free electrons. Titanium dioxide forms a positively charged hole in the valence band, thus forming an electron-hole pair. By utilizing the oxidation of the generated cavity and the reducing capability of free electrons, the titanium dioxide reacts with moisture H2O and O2 contacted with the surface to generate free radicals with extremely strong oxidizing power, and the free radicals can decompose and break functional bonds of all organic matters, change the structure of organic matter molecules in waste gas, change hydrogen (H) and carbon (C) contained in the waste gas into water and carbon dioxide, and degrade and purify organic waste gas and malodorous molecules.
Low temperature plasma deodorization equipment: in the high-frequency high-voltage electric field discharging process, electrons acquire energy from an electric field, the energy is converted into the internal energy or kinetic energy of pollutant molecules through inelastic collision, the molecules acquired energy are excited or ionized to form active groups, meanwhile, oxygen and moisture in the air can generate a large number of active groups such as nascent hydrogen, active oxygen and hydroxyl oxygen under the action of the high-energy electrons, and a series of complex physical and chemical reactions are initiated after the active groups collide with each other.

The malodorous gas is subjected to pretreatment processes such as dust removal, cooling and dehydration. Firstly, the odor is collected and conveyed to a humidifying and heat preserving system, and in a biological filter tank containing rich microorganisms, the odor passes through a filter bed composed of filter materials from bottom to top, and the odor gas is transferred to a water-microorganism mixed phase from a gas phase and is decomposed through the metabolism of microorganisms fixed on the filter materials. The microbial deodorization process is divided into three steps:

(2) The odor dissolved in the water is absorbed by the microorganism through the cell wall and the cell membrane of the microorganism, the odor insoluble in the water is firstly attached to the outside of the microorganism, and the extracellular enzyme secreted by the microorganism is decomposed into soluble substances and then permeates into the cells. The odor components in the liquid phase (or solid surface biological layer) are adsorbed and absorbed by microorganisms, and the odor components are transferred into the microorganisms from the water;
(3) Malodorous components entering the cells of the microorganism are used as nutrient substances to be oxidized, decomposed, assimilated and synthesized by the microorganism, and part of the generated metabolic products are dissolved in human liquid phase, part of the generated metabolic products are used as cell substances or cell metabolic energy sources, and the other part of the generated metabolic products (such as CO 2) are separated out into the air.

The automatic heating of the combustion equipment sends hot air into the saturated adsorbent through a fan, heats and 'evaporates' organic matters from the adsorbent, and the desorbed waste gas belongs to organic waste gas with high concentration, small air quantity and high temperature.

However, the time of each production stage is not fixed although regular, and may be performed simultaneously, and timing or manual switching may result in low accuracy, imprecise exhaust treatment, and insufficient intelligence. Thus:

Specific training may be to adopt techniques such as loss function, which will not be described in detail in this patent.

It should be noted that, the weight value of each path is set according to the average use cost of the corresponding path, for example, the higher the average use cost of one path is, the lower the weight value corresponding to the one path is. Mode 3 balances the cost of the fee processing and the cost of the path usage, thereby providing a solution for both.
The control system also acquires exhaust gas detection data of an outlet of the chimney discharge system and judges whether the exhaust gas treated by the current path reaches a preset standard.
