In the utility model, the pressure in the hot-ring ammonia water tank 1 is effectively ensured by adopting the hot-ring ammonia water tank breather valve 8, and the dynamic balance of the hot-ring ammonia water in the hot-ring ammonia water tank 1 is ensured.
The utility model adopts the breathing valve 8 of the hot-ring ammonia water tank, which further protects the hot-ring ammonia water tank 1 due to the action of the breathing valve.
In the utility model, the hot ring ammonia water tank breather valve 8 is an existing mature product, and can be directly purchased and used in the market, and further description of the utility model will not be provided.
The reason why the hot ring ammonia water tank breather valve 8 is selected in the utility model is as follows: the breather valve is a valve which can ensure that the space of a storage tank (a hot ring ammonia water tank 1) is isolated from the atmosphere in a certain pressure range and can be communicated with (breathe) the atmosphere when the pressure range is exceeded or undershot. Its function is to prevent the tank from being damaged by overpressure or vacuum, and at the same time to reduce evaporation loss of the liquid. The breather valve can reduce the gas emission in the tank, thereby reducing the pollution to the atmosphere, and the storage tank can avoid damage caused by overpressure or instability caused by super vacuum, thereby playing a certain role in promoting safety and environmental protection.
In the utility model, the hot ring ammonia water tank breather valve 8 at least comprises a valve seat, a valve cover, a protective cover and two groups of opening and closing devices controlled by vacuum and pressure. The opening and closing device comprises a valve clack, a guide rod, a spring seat, a sealing ring and the like. When the pressure in the tank reaches the rated exhalation positive pressure, the pressure valve clack is opened, and vapor in the tank is discharged; when the vacuum degree in the tank reaches the rated suction negative pressure, the vacuum valve clack is opened, and air enters. The breather valve is a safe and energy-saving product for maintaining the air pressure balance of the storage tank and reducing the volatilization of the medium. The breather valve fully utilizes the pressure bearing capacity of the storage tank to reduce medium discharge, and the principle is that the weight of a positive and negative pressure valve disc is utilized to control the positive exhaust pressure and the negative suction pressure of the storage tank; when the medium is pumped out of the tank, the pressure of the upper gas space in the tank is reduced, and when the operation negative pressure of the breather valve is reached, the negative pressure valve disc of the breather valve is jacked up by the atmosphere outside the tank, so that the external gas enters the tank, the pressure in the tank is not reduced continuously, and the pressure in the tank and the pressure outside the tank are balanced, so that the safety device of the storage tank is protected. The storage tanks are all closed hot ring ammonia water tanks 1 in the utility model.
According to the utility model, through reasonably designing the radiator and the nozzle, the waste heat of the thermal circulation ammonia water with more impurities can be utilized, the corridor is heated, and the normal operation of the coal conveying belt in the winter corridor is ensured. The utility model has simple structure and simple flow, and can heat the belt corridor by utilizing waste heat which is originally lost to the environment under the condition that the main process and the heat balance in the original factory are not influenced, so that the temperature of the corridor is higher than 5 ℃, and the situation that the belt is not frozen in winter is ensured.
According to the utility model, the thermal circulation ammonia water is introduced into the plate heat exchanger, and the waste heat of the thermal circulation ammonia water is utilized to heat the coal conveying corridor in the factory, so that the problems that the coal conveying belt in the semi-coke enterprise in winter in cold areas is frozen and slipped, cannot be used normally and the like can be avoided. Because the coal contains moisture, part of the water is separated out on the belt in the transportation process of the coal conveying belt, and after the belt stops running, the moisture remained on the belt can freeze, so that the belt cannot be started. By adopting the device provided by the utility model, the coal conveying corridor is heated, so that the coal conveying belt is prevented from icing in the transportation process, and the problem that the belt cannot be started due to low temperature is solved.
The utility model adopts the totally-enclosed hot-ring ammonia water tank 1, the straight-through heat exchanger 4 with the overhaul hole, the nozzle 6 and the gas collecting tank 10 to utilize high-temperature gas in the gas collecting tank 10, and the hot-ring ammonia water tank 1 is provided with the hot-ring ammonia water tank breather valve 8 and the nitrogen sealing device, so that the nitrogen sealing device does not need external energy, can work in occasions without electricity and gas, is convenient, saves energy and reduces cost. The nitrogen sealing device is used for keeping the pressure of protective gas (generally nitrogen) at the top of the container constant so as to avoid direct contact between materials in the container and air, prevent the materials from volatilizing and being oxidized and ensure the safety of the container. In the utility model, the nitrogen sealing device and the hot ring ammonia water tank breather valve 8 are all existing mature products, can be directly purchased and used in the utility model, and will not be further described in the utility model.
